Figure 17 is a diagrammatic view illustrating various power operated members of my novel record shifting device together with, electrical control means and circuits associated therewith.

In order that the invention may be clearly understood, I have shown a portion of a phonograph cabinet or case A having side walls a and a shelf or partition a disposed in a horizontal plane intermediate the side walls a for supporting a motor B and a turntable C. The cabinet is also shown provided with a second wall or shelf a" arranged above the partition a for supporting a tone arm D in cooperative relation with the turntable C.

The motor B is preferably of the electric type and may be of any suitable construction. This motor as shown in Figure 1 is secured to the lower side of the shelf a and has the armature shaft b thereof journaled at its outer end in a suitable bracket I also secured to the shelf a". The turntable C has the shaft c thereof journaled in a suitable bearing support 2 secured to the upper portion of the shelf a and which is connected with the motor shaft b by a bevel gear 3 secured to the turntable shaft and a similar bevel gear 3' mounted on the motor shaft b.

The tone arm D having the reproducer d carried thereby, may be connected in any suitable manner with the usual amplifier, not shown, and may be operated in any suitable manner relative to the amplifier and supporting shelf a" to swing in the usual manner across the surface of a record E on the-turntable C for reproducing sound'from the record in the usual manner.

trated in the drawings comprises primarily a record magazine 4 secured to the cabinet A above the turntable C and preferably at the rear thereof, a record selector and carrier mechanism i'mounted in cooperative relation with the magazine and with the turntable C for movement relative to both of these members and a power operated means 6 actuated by the motor B for operating the selector and carrier mechanism.

The record magazine 4 as shown comprises a plurality of, in this instance, thirteen upright frames 8 composed of wire. secured to a pair of side rails 9 arranged one at either side of the wire frames and fixedlysecured to a respective side Wall aof the cabinet by brackets III as shown in Figures 1 and 15. The frames 8 are arranged in parallel relation with each other longitudinally of the rails 9 and are spaced apart a distance to readily receive a phonograph disc record therebetween.

The side rails 9 extend in parallel relation to each other from a position over the turntable rearwardly to a position at the rear of the magazine frames 8 for supporting the record selector and carrier mechanism 5 in cooperative relation with the frames 8. These side rails 9 are preferably in the form of channel members with the channeled sides thereof facing inwardly toward each other to form a track for supportably receiving wheels II rotatably connected to opposite sides of a carriage I2 mounted beneath the magazine frames 8 for movement longitudinally of the rails relative to said frames. This carriage I2 comprises two side members I3 to which the wheels II are secured and a horizontally disposed platform I! which connects the side members and extends in a horizontal plane beneath the magazine frames 8 in close proximity thereto.

This platform I4 is provided with an opening I5 which extends longitudinally thereof substantially midway between the sides of the carriage. The platform I4 is also provided with a pair of slots I 6, see Figure 15, arranged one on either side of the opening I5. These slots I6 extend outwardly from the corresponding side of opening I5 intermediate the ends thereof and in aligned relation with each other toward the respective longitudinal sides of the platform. These slots I6 are of slightly greater width and over all length than that of the largest record to be mounted in the magazine to receive the record therethrough. The slots I6 and the frames 8 are preferably arranged at a slight inclination to the. vertical as indicated in Figures 6, 8, and 16 so that when the record is supported by the frames the same will be maintained slightly inclined from the perpendicular toward the turntable. Each side wall of the slots I6 adjacent the opening I5 has the upper edge thereof beveled as at IE to permit a record when being returned to the magazine to readily move into contact with the upper surface of the platform I4 adjacent the opening I5 in a manner which will hereinafter be more apparent.

Secured to the carriage I2 to move therewith is a record guide means I8 which in this instance comprises a stationary track I9 and a movable track 20. The stationary track I! is substantially a U-shaped member having the transverse portiorl thereof arranged uppermost and connected by means of rearwardly extending arms 2| and a pendant support 22 to the rear end of the carriage I2 so that the arms as 23 extend These frames are of the slots IS. The greater portion of arms 23 extend downwardly from the transverse portion of the guide track in slightly diverging planes in substantially the same angle of inclination as .the frame member 8. The lower ends of the arms 23 terminate in a horizontal plane a relatively short distance above the turntable C and are slightly curved forwardly 'for assisting in guiding the record to a horizontal position over the turntable.

The movable guide track 20 is also a substantially U-shaped member having the side arms 24 thereof spaced apart adistance greater than the diameter of the turntable Cand less than the diameter of the smallest record to be played as illustrated in Figure 9. The free ends of the arms 24 are pivotally secured as at 25, Figures 6, 8, 9 and 14 to the carriage |2 one at either side of the stationary track 23 and opening l5 and with the forward edge thereof in alignment with the rear edges of the slots It. The arms 24 extend downwardly in substantially straight lines from the pivots 25 and then are curved forwardly so that when the upper portions thereof lie in a plane substantially parallel with the forward edges of the upper portion of the arms 23 the lower or forward portions 24. thereof will extend in substantially a horizontal plane above the turntable C as shown in Figure 6 and with the transverse portion .26 of the track positioned forwardly of the turntableas shown in Figure 9. It will now be seen that the movable track 20 may swing about the pivots 25 from a position with the lower portion 24 of the arms 24 located in a horizontal plane above the turntable as shown in Figure 6 when the rear or upper portion of the arms are in the transverse plane of the upper portions of the arms 23 to a position below said turntable as shown in Figure 7.

The means for operating the movable guide track 20 to bring the forward portions 24' of the side arms thereof from the position above the turntable C to a position below said turntable after described.

and return, comprises a pair of cams 28 mounted on a horizontally disposed cam shaft 29 which extends transversely through the cabinet A in a plane below the turntable C and at one side of the turntable shaft 0. This shaft 29 as shown in Figure 1 has the ends thereof journaled in suitable bearing supports 30 secured to a corresponding side wall a of the cabinet and which is rotated by the motor B in the manner herein- The carriage I2 is intermittently moved rela I tive to the magazine frames 8 to bring the slots I6 and the guide tracks l9 and 2|! into cooperative alignment with the chambers 8' between said frames as shown in Figures 6, 10 and 11 by the mechanism which will now be described. Secured to or made integral with the carriage I2 is a rack 32 which is positioned along one longitudinal side of the carriage'beneath the platform l4 as shown in Figures 1 and 10. This rack 32 is provided with at least as many teeth as there are record chambers 81in the magazine 4 and they are spaced apart a distance'substantially equal to the distance betweenadjacent chambers. Mounted beneath therack 32 is an operating pawl or detent 33 which is connected by a pin 34 to a supporting block or bracket 35 secured to the adjacent side wall a of the cabinet A. This pin 34 extends through an elongated slot 34' formed in the detent 33 intermediate the ends thereof. A spring 3G..connected with the forward end of the detent and with the'support a yieldingly end portion of the detent and limits the swinging movement of said detent produced by the spring 36. The rear end.'of the detent 33 ispivotally connected as at '33 with one arm of a bell-crank lever 33 which is secured by means of a pin 40 with the support 35. The pin '40 extends through an elongated slot 40' as shown in Figure 10 arranged below the pivot 38. The other arm as 39' of said bell-crank lever is connected with a spring 4| secured to the support 35 andwhich normally urges the outer end of the arm 39' upwardly This upward movement of the arm 39' is lTmited by a stop pin 42 secured to the support 35.

The bell-crank lever 39 is operatively connected with a cam follower 44 by means of .a link 45 pivotally connected at one end as at 46 to the arm 39 of the bell-crank lever intermediate the ends thereof. The other end of the link 45 is pivotally connected as at 41 with the cam follower 44 which in turn is pivotally secured as at 48 to a supporting bracket 49 mounted upon the shelf a at the rear of the cam shaft 29 as shown in Figure 6. The cam follower 44 in this instance is an L-shaped member with one leg 44' thereof extending upwardly from the pivot 48 through a slot 50 provided in a guide member 5| connected with the bracket 49. The cam follower 44 is maintained in operative engagement with a cam 53 by means of the spring 4| acting upon the lever 39'.

The cam 53 is secured to avertically disposed shaft 54 which is journaled in the bracket 49. The shaft 54 extends upwardly some distance above the cam 53 and has the upper end thereof secured to a bevel gear 55 which is in meshing engagement with a bevel gear 56 secured to a horizontally disposed stub shaft 51 which is journaled in a bracket 58 secured to the shelf or partition (1'. The shaft 51 is driven by the cam shaft 29 at one-half the speed of said cam shaft by means of a shaft Gli'journaled in a bracket 6| secured to the partition 1'. One end of the shaft 60 is connected with the shaft 51 by a relatively large bevel gear 62 secured to the latter shaft and a pinion 83 secured to the shaft 60. The other end of shaft 60 is connected with cam shaft 29 by a pair of bevel gears 64 as shown in Figure 13.

The cam 53 is of disc formation having a smooth peripheral edge with the exception of a slight cam indentation or recess 53' formed therein adapted to receive the adjacent portion of the cam follower 44 therein to effect rocking of said follower about its pivot 48. The cam 53 is pro-' vided with a switch actuating pin 35 which is secured thereto diametrically oppositethe recess 53'. This pin 66 projects below the adjacent portion of the 'cam 53 for engagement with one of the contact members 61 of a control switch 68- when the cam follower 44 is in engagement'with the slot 53 for opening said switch. Associated with the cam 53 is a second switch 69 arranged about the shaft 54 in right-angular relation with the switch 68. This switch 69 has one of the contact arms as 10 thereof projecting into the path of movement of the pin 66 to be moved thereby out of electrical connection with the other contact member as 10' of the switch These switches 63 and Glare actuated bythe pin 66 on the cam 53 for controlling the drive connection between the motor shaft 1) and the'cam shaft 29 in a manner and for a purpose which will hereinafter be described.

The means as shown in Figures 1 and 2 for operativel'y connecting the cam shaft 29 with the motor shaft 1) comprises a relatively large spur gear 12 secured to the cam shaft to rotate therewith, an idle gear 13 rotatably mounted upon a shaft 14 secured to the bracket I and a similar bracket I mounted on the wall or shelf a and a relatively small spur gear 15 mounted on the shaft 12.

It will be observed by referring to Figures 1 and 3 that the gear 15 is arranged in spaced. relation longitudinally of the shaft b to the gear member 3'. Furthermore, both of these gear members 15 and 3' are rotatably mounted upon the shaft b and have their adjacent surfaces provided with clutch elements 16 and TI respectively, which are adapted to be engaged by a clutch member 18 slidably mounted upon the shaft b intermediate the gear members 16 and 3'. This clutch member 18 is keyed to the shaft 1) as indicated in Figure 3 so as to rotate with said shaft and is moved longitudinally of said shaft to bring the same into and out of forked engagement with the clutch members 16 and l! by means of a forked arm 19. This arm 19 is pivotally connected interme diate its end as at 80 to a bracket 8|, Figure 1, secured to the lower surface of the shelf or wall a. The rear end portion of the arm 19 is composed of magnetizable metal and is mounted between a pair of electro- magnets 82 and 83 which may be secured in any suitable manner to the wall a in cooperative relation with the arm 19 for actuating said arm when energized.

It is thus seen that when the clutch member 18 is in engagement with the clutch element 16, the cam shaft 29 will be rotated by the motor shaft b through the medium of the gears 15, 13 and 12 while the turntable C may remain stationary. When the clutch 18 is moved into clutching engagement with the clutch element 11 the motor shaft b will be connected from the gear 15 and cam shaft 29 and will be operatively connected with the gear 3 and turntable shaft c. It will now be observed that while the turntable C is operated at a relatively high rate of speed by the motor B, the cam shaft 29 is operated at a much slower rateof speed depending upon the relative sizes of the gear member 15' and 12. Furthermore, it will be observed that the cam 53 for intermittently actuating the carriage i2 is rotated at one-half the speed of the cam shaft 29 so that the detent 33 is actuated to move the carriage one tooth space due to the engagement of the cam follower 44 with the cam recess 53' but once during two revolutions of the cam shaft. The manner in which the cam 53 effects the intermittent movement of the carriage will be readily understood by referring to Figures 10 and 11.

It will be observed by referring to Figure 10 that when the cam follower 44 is in registration with the cam recess 53 the spring 36 will maintain the forward end of the detent 33 in its lowermost position as determined by stop pin 31. At the same time the detent will be urged forwardly so as to maintain the pivotal pin 34 in engagement with the rear end of the slot 35. This action of the spring 36 upon the detent 33 also maintains the vertical leg of the bell-crank 39 in its uppermost position with the pivotal pin 49 positioned at the lower end of the slot 40. The spring is of sufficient tension to maintain the arm 39 in engagement with the stop pin 42 when the cam follower is in registration with the cam recess 53' and thereby urge the free end of the cam follower toward the cam into engagement therewith. As the cam 53 is rotated in the direction of the arrow X in Figure 12, the cam follower is rocked about its pivot 48 as the recess 53 is moved beyond the said follower. During the initial rocking movement of the cam follower 44 thus produced the vertical leg of the bell-crank 39 is drawn downwardly until the pin 40 is in engagement with the upper end of the recess 40' as shown by full lines in Figure 11 due to the spring 4| being stronger than the spring 36. This downward movement of the bell-crank lever 39 effects the forward swinging movement of the forward end of the detent 33 and brings the same into operative engagement with the tooth in the rack 32 aligned therewith. As the cam follower continues to be rocked about its'pivot 48 as the same moves from the cam recess 35 into contact with the peripheral surface of the cam, the bell-crank lever 39 will be rocked about the pin 40 as a pivot against the action of the spring 4|, that is, to the position indicated by broken lines in Figure 11. This rocking of the bell-crank lever 39 draws the detent 33 rearwardly a sufficient distance to move the rack 32 and therefore the carriage l2 rearwardly one tooth space.

It will now be observed that inasmuch as the cam follower '44 is maintained in the rocked position until the cam 53 has made substantially one complete revolution, the detent 33 will be maintained in holding engagement with the rack 32 and will thereby lock the carriage l2 against being moved relative to the magazine 4 until the detent 33 is again moved out of engagement with the rack 32 as the cam follower 44 again moves into the cam recess 53'. As said follower engages said recess the detent 33 will be moved out of engagement with the rack 32 and returned .shown the carriage provided with a lever 85 which is shown in Figure 15 secured to the forward edge portion of the platform I4 and extends laterally therefrom over the adjacent side rail 9 and through an elongated slot 86 provided in the adjacent side wall a of the cabinet A to the exterior of said cabinet. It will now be ap parent that as the carriage I2 is moved longitudinally of the supporting rails 9 whether manually through the medium of the lever 85 or by power means through the medium of the detent 33 and rack 32, the slots I 6 will be brought into successive alignment with the chambers 8 of the magazine 4. As the slots I6 thus register with each chamber 8, the record E contained in said chamber will be in position to pass downwardly through the slots l6 and onto the guide tracks l9 and 29, while the remaining records will be maintained in the chambers by the engagement of said records with the portions of the platform l4 extending along the sides of the opening l5.

In order to control the movement of the recnally ords through the slots I8 I have provided a pair of record carrier arms 88 which are'securedvat their forward ends to a shaft 89 journaled in the forward ends of the side rails 9 as illustrated in Figures 1, 6 and 15 so as to rotate with said shaft. These arms extend rearwardly from the shaft 89 in parallel spaced relation with each other and with each arm positioned-within the openingv I5 in close proximity with a respective side of said opening: The upper surface of thearms 88 when the arms are in their normal po-v sition within the opening I5, are arranged in a horizontal plane a slight distance above the lower corner of the beveled or chamfered portions I8 of the slots as shown in Figures 9, 14 and 16. It is thus seen that the record in alignment with the slotswill be maintained against movement through said slots by. arms 88. Furthermore arms 88 hold the record in a sufficient elevated position to enable the record to be movedupwardly by the chamfered portion I8 of the slots as the carriage is moved longitudirelative to said record in either direction and into engagement with the upper surface of the platform I4 adjacent the opening I5 whereby the record will be maintained in its normal position within the magazine t.

It will now be understood that the record E aligned ;,with the slots I8 and maintained against downward movement by the arms 88 will pass slots onto the tracks I9 and 28 upon downward swinging movement of thearms. This swinging movement of the arms 88 is produced by a cam 98 secured to the cam shaft 29 adjacent one end thereof. Cam

98 is operatively connected with the shaft 89 by a cam follower arm 9I which is rotatably -mounted upon a shaft 92, see Figure 6, positioned in a horizontal plane in front of the cam shaft 29 and which extends transversely through the cabinet A with the ends thereof secured ,in any suitable manner to the side walls a of said cabinet. This arm 9| extends rearwardly from the shaft 92 over the cam 98 into engagement with the periphery thereof and is yieldingly maintained in contact with said cam by a spring 98 connected with the free end of the arm and with the partition 11. The arm 9| ispivotally connected to one end of a link 95 which extends upwardly from said arm and has the upper end thereof pivotally connected to a rock arm 98 secured to one end of the shaft 89. As the record carrier arms 88,are thus moved downwardly from the uppermost position as illustrated by full lines in Figure 8 to their lower or outermost position as illustrated by broken lines in said figure; the record aligned with the slots I8 will follow said arms downwardly and be guided by the guide tracks I9 and 28 to a position over the tion on the movable forward edge of the record turntable 0 into engagement with the horizontal portions 24' of them'ovable guide track 28 as shown byv broken lines in Figure 6..

As the record approaches the horizontal po siguide member 28 arms 88 with-the record and the will engage a pair of record positioning fingers 98 arranged at the forward side of the turntable C." These guide fingers 98 are rotatably mounted on ahorizontally disposed shaft 99 which is secured to apair move out of contact of brackets I88 mounted on the partitiona at the forward side of the cam shaft 29 as illustrated in Figure 7. A similar pair of record positioning fingers side of the turntable C diametrically opposite I the record downwardly onto permitted by the action of the cams 28 upon the p A movable track 28 which permits the forward-por- These arms Ill normally I8I are positioned at the rear the positioning fingers 98. These rearwardly positioned fingers I8I are rotatably mounted on a shaft I82 secured to brackets I83 also mounted on the partition 0.. The fingers I8I are operatively connected with the fingers 98 by means of 5 a rod I84 which is connected at its forward end to an extension 98' of one of the fingers 98 projecting below the shaft 99. The other end of the rod I84 is pivotally connected with one of the fingers I8I. at a point abovethe shaft I82 so that the forwardly and rearwardly positioned fingers will simultaneously rock in a direction toward or from each other to bring them into and out of cooperative engagement with a record. a 7

As shown in Figures 1 and 7, the means for 15 operating these fingers 98 and IM comprises a cam I88 secured to the cam shaft 29. A cam follower pin or roller I81 adapted to engage the peripheral surface of the cam M5 is operatively connected with a rock arm 188 which has the forward end thereof rotatably mounted upon the shaft 92. This arm I88 extends rearwardly from the shaft 92 to some distance beyond the cam- I88 and has the inner or free end thereof connected to a spring I89 which is also connected with a rod II8 extending transversely through the case A, said rod having the ends thereof connected with the side walls a of the case by any suitable means. The rock arm I88 is operatively connectedpwith one of the rearwardly positioned fingers I8I by a link III pivotally connected with said arm at one end and having the other end pivotally connected to a pendant portion I8I' of one of said arms. The length of the rod I84 and the relation of the pivotal connections thereof with the fingers 98 and I8! relative to the pivotal shafts 99 and I82 is such that, when the fingers are in their outermost positions they will be spaced-apart at their upper ends a distance greater than the diameter of the largest record to be played.

The pivots 99 and I82 for the fingers 98 and IM are positioned at equal distances either side of the turntable shaft 0 so that as said fingers are moved inwardly toward each other the record engaged thereby will be brought into concentric relation with theturntable C. This movement of the fingers toward each other is produced by the spring. I89 through the medium of the arm I89 and link III when the cam follower I8! is in registration with the recess l88'vof the cam I88. It will therefore be seen that irrespective of the size of the record said record will be brought into concentric relation with the turntable C as the arm I88 is'released by the cam I88. continues to rotate the engagement of the wall of the recess I88 with camfollower I8! will rock the fingers 98 and IN outwardly in directions away from the turntable and thereby release said record and permit the same to moveinto engagement with the turntable C.

This movement of 9 the turntable C- is tion of said track to move downwardly simultaneously with the engagement of the fingers 98 1 and IM with 'therecord.

The records E are removed from the turntable C by means of a pair of record lifting or reversing arms Ill positioned one at either side of the 70 turntable C as illustrated in FiguresB and 9.

extend from a posi-d tion in front of the turntable to a position at the rear thereof and are mountedv to swing intermediate the arms of the movable track 28. 15

As the cam The rear end portions II 4' of the arms II 4 extend upwardly at substantially right-angles to the remaining portions thereof and are secured to a shaft II 5 which is disposed in a horizontal plane at the rear of the turntable C intermediate said turntable and the lower ends of the arms 23 of the stationary track I3. The shaft H5 is rotatably supported in the upper ends of a pair of brackets II6 secured to the partition a.

It will now be understood that as the arms I I4 swing upwardly a record. contained on the turntable C will first be lifted from said turntable and as the arms proceed in their upward movement the rear edge of the record will engage the portions II4 of the arms so that the record will be lifted thereby to a plane above the turntable with the lower edge of the record positioned above the path of movement of the outer or free ends of the record carrying arms 88. The arms II4 are swung to a position slightly beyond the vertical so'that the upper end portion of the record carrier thereby will swing by gravity rearwardly relative to the turntable into engagement with the stationary guide track I9 asthe arms II4 approach the extreme upper position of their movement as illustrated by broken lines in Figure 8.

It will thus be seen that the record in moving from the turntable C to the inclined position in engagement with the stationary guide track I8 will be positioned with the opposite side thereof facing forwardly from that when the record was moved downwardly from the magazine.

It therefore follows that when the record is again moved onto the turntable the opposite or reverse side thereof will be facing upwardly in position to be played. The means for operating the record reversing arms II4 comprises a cam II8 secured to the cam shaft 28 as shown in Figures 1 and 8. This cam II8 engages a cam follower H9 in the form of a pin or roller which is operatively connected witha rock arm I20. This rock arm has the forward end thereof rotatably mounted upon the shaft 92 and extends rearwardly from said shaft to a considerable distance at the rear of the shaft 23. The cam follower I I9 is yieldingly maintained in engagement with the peripheral surface of the cam II8 by spring I2I which has one end connected with the free end of the arms I and the other end thereof secured to the rod I I0. The arm I20 is operatively connected with the arms II4 by a link I22 pivotally connected with the arm I20 intermediate the spring I2I and the cam follower H9. The other end of the link I22 is pivotally connected with a crank arm I23 secured to or made integral with one of the record reversing arms II4 to project 'rearwardly, from the shaft I I5.

Associated with the carriage I2 is a manually operated control means which is adapted to coact with the means for operating the record carrier arms 88 and the record reversing arms II4 whereby any one or number of the records contained in the magazine 4 may be played either on one side or on both sides. This control mechanism, as illustrated in Figures 4, 5 and 15, comprises a plurality of, in this instance, 12 contact control arms I25, one for each magazine compartment 8'. These contact control arms are composed of brass or the like and are rotatably mounted upon a shaft I26 as shown in Figures 4 and 5 in electrical contact there with. This shaft I23 is secured at its ends in supporting plates I21 which are secured to the lower side of one of the side rails 8 by brackets I28. The supporting plates I21 and shaft I26 are electrically by spacing sleeves I30 mounted upon the shaft I26 intermediate adjacent arms and spring members I3I mounted between the outermost arms and the adjacent supporting plates I21.-

It will now be understood that the co-action of the spring I3I and spacing sleeves I30 will frictionally maintain the contact arms I in predetermined rotary positions relative to the shaft I26. The sleeves I are constructed to maintain the adjacent arms I25 spaced from each other a distance equal to the distance adjacent compartments 8' of the magazine 4 are spaced from each other. Mounted upon the carriage I2 is a spring contact member I33 which is secured to said carriage in insulated spaced relation therewith and in predetermined relation with the slots I6 by any suitable means. This spring contact member I33 as illustrated in Figure 4 extends downwardly beneath the carriage into the horizontal plane of the shaft I26 and has the lower end thereof formed arcuate as at I33 for contacting with the inner end of each of the arms I25 when the slots I 6 are in registration with a corresponding record chamber 8'. The arms I 25 are constructed in such a manner that when moved to a position inclined to the horizontal as illustrated by broken lines in Figure 4 they will be out of the path of movement of the contact member I33. The contact member I33 extends upwardly along one side of the carriage I2 and has the upper end thereof connected to a contact plate I35 which extends longitudinally of the carriage along the upper face thereof a distance equal to or 'greater than the longitudinal movement of the carriage and which is secured to said carriage in insulated spaced relation therewith.

Mounted upon the side rail 3 which carries the contact arm I25 is a yielding contact member I36 which is secured to said rail in insulated spaced relation therewith and extends inwardly therefrom over the adjacent edge of the carriage I2 into sliding contact with the plate I35 for electrically maintaining said plate and the spring contact member I33 in electrical connection with a source of potential during the reciprocating movement of the carriage.

The operation of the apparatus will now be readily understood by referring to Figure 17 of the drawings in connection with the remaining figures thereof. Electrical energy is obtained from conductors I40 and MI connected with any suitable source of potential. The positive conductor as I 40 is provided with a manually operated control switch I42 and when said switch is closed current is supplied by wire I43 to the motor B which is maintained in operation for driving the shafts b and clutch member 18. At the beginning of the operation of playing one or more of a series of records contained in the magazine 4, the clutch I8 will be in engagement with the clutch element 16 and the tone arm D will be in the inoperative position at one side of the turntable C as illustrated in Figure 8, so that when the switch I42 is closed the cam shaft 20 will be operated by the motor B. Prior to the closing of switch I42 the carriage which will then be released by the detent 33 as shown in Figure 10, may be first operated by hand by means of the handle 85 to bring the slots I6 into predetermined relation with the first record desired to be played.

In this instance the carriage is so positioned that the slots I6 are positioned one space in advance of the record to be played.

It will now be apparent that during the initial operation of the motor B and shaft b the cam 53 operated by the cam shaft 29 will actuate the cam follower 44 to first bring the detent 33 into engagement with the rack 32 and then move the carriage one tooth space rearwardly in the manner hereinbefore described and thereby bring the slots I6 into cooperative alignment with the selected record. As the carriage is thus moved into cooperative relation with the selected record the cam 90 will have been moved from the position shown in Figure 6 in the direction indicated by the arrow Y to bring the forward portion thereof into contact with the cam follower arm 9i. As the cam 90 continuesto rotate it will rock the arm 9| from the position shown by full lines in Figure 6 to the position indicated by broken lines in said figure. During this movement of the arm 9| the record carrying arms 88 will be moved. downwardly about the axis of the shaft 89, thereby permitting the record inalignment with the slots I6 and which rests upon the arms 88, 'to move downwardly. The record is guided -in itsdownward movement by the co-action of the arms 88 and guide tracks I 9 and 20. to nearly a horizontal position, as indicated by broken lines in Figure 6, over the turntable C and into engagement with the forwardly located record positioning fingers '98.

During the initial rotation of the cani shaft 29 it will be understood that the movable guide track 20 will be maintained in it's normal uppermost position by the cams 25. Prior to the engagement of the record with the fingers 98 the record operating arms 88 will have moved forwardly out of engagement with'the record, due to a slowing up in the movement of the record as it assumes the horizontal position. As the record moves into engagement with the fingers 98 it will pass beyond the lower end of the stationary guide track I9 so that it will then be entirely supported by said fingers and the movable guide track 20.

The fingers 98 are so related to the turntable C when in their outermost inoperative positions that the record engaging said fingers will be maintained thereby with the center thereof positioned in advance of the center of the turntable C.

As the record E engages the fingers 98 the movable guide track 20 is permitted to commence the downward swinging movement thereof by the cams 28. At about the time the track 2|! begins the downward movement or shortly thereafter the arm N18 is released by the registration ofthe cam recess I06 in the cam I06 with thecam follower Ill'I. As thearm I08 is thus released the spring I59 actuatesv said arm to produce move-' ment of the fingers 98, and IM toward each other and will bring them into engagement with the adjacent peripheral edge of the record irrespective of whether a ten inch record or a twelve inch record is being positioned upon the. turntable' It will be observed that during the movement of the fingers toward eachother; the record will be brought into concentric relation with, the turntable. C due to the flngers88 and IIII being moved toward each, other with a uniform movement and also to the fact that the fingers'of each pair engage the record at equal distances either side of the vertical plane passing through.

the'c'enter' of'the turntable longitudinally of the tracks I9 and 20. At about the time the fingers have thus brought the record into concentric reof switch I50 due to a control element or lug connectedwith the tone arm .being moved out of 45 lation with the turntable C the movable track 20 will be in substantially the plane of the upper face of the table during its downward movement. The fingers 98 and IIII are thenmoved outwardly to release the record by'the engagement of the cam I05 with the cam follower II'I'I thereby placing the record upon the turntable in concentric relation therewith and with the usual centering pin as c" of the turntable engaging in ,the center hole of the record. After the record has 10 been thus placed upon the turntable C the movable track is permitted to swing to a position below the turntable as illustrated by full lines in Figure '7. During this movement of the record positioning members, the cam shaft 29 will hav"e 15 been rotated 180 at which time aswitch control pin or member I2 connected with the gear 12 mounted on the cam shaft will engage a contact member I44 of a normally open switch I45 and close said switch. This switch is connected by 0 a wire I46 with the electro-magnet 82 and positive conductor I40. It will thus be seen that as soon as the switch I45 is closed a circuit is completed through the electro-magnet B2, switch I45, wire I41, wire I48 and thence through the normally closed switch 69, wire I49 and a second normally closed switch I50 andwire I5l to the negative conductor MI. The electro-magnet 82 is thereby energized which effects themovement of the clutch member I8 out of engagement with the clutch element 16,

needle carried thereby inengagement with the record on the turntable by any suitable means. The movement of .the tone arm D into operative engagement with the record effects the opening cooperative engagement with one of the contact arms as I of the switch I50 thereby opening the circuit associated with the electro-magnet 82 and causing said electro-magnet to be deenergized. 50

The record on the turntable is now played in the usual manner after which the tone arm D may bereturned to itsinitial inoperative position manually or by a suitable power operating means not shown.' During the movement of the tone arm D to the inoperative position thereof and before said tone arm reaches said inoperative posi tion,- a normally open switch I54 is momentarily closed by the engagement of a switch operating member I56, also connected with the tone arm D, with one of the contact members as I54 of said switch. It will be'understood that the member I 55, as shown in Figure 17, will move outwardly beyond contact member I54 as the tone arm D moves toward the center of the record on turn- 5' wire I55to 'the switch I54 'and thence through wire I5I to the negative conductor MI. The electro-magnet 83 thereby energized will effect, movement of the clutch member I8 out of en- '7 gagement with the clutch element 11 and into the contact member I44 of the switch I45 per-- mitting said latter switch to open and thus maintaining the electro-magnet 82 de-energized until the gear 12 is rotated three hundred sixty degrees.

As .soon as the cam shaft 29 is thus connected with the drive shaft b the record reversing arms II4 will be actuated by the engagement of the cam III) with the cam follower II9 to produce upward swinging movement of said arms. During this swinging movement of the arms II4 the record will be liftedfrom the turntable and brought into engagement with the stationary guide track I9 as illustrated by broken lines in Figure 8. During this upward swinging movement of the arms I I4 the arms 88 are moved rearwardly toward the record so that as the record engages the stationary track the record carrying arms 88 will engage the lower edge of said record, lift the record'from the arms H4 and move the same upwardly through the slots I6 into the compartment 8 of the magazine 4 previously occupied by said record. As the record is thus returned to the magazine 4 the switch control member 12 will be in its initial position,

\ switch I45 will remain open, the clutch 18 will remain in engagement with the clutch element 16 and the cam shaft 29 will continue to be operated by the drive shaft 2).

.It will now be observed that during this movement of the record operating mechanism to bring the record from the magazine onto the turntable and to return said record to the magazine, the cam shaft 29 will have rotated one complete revolution while the cam 53 will have rotated but one-half of a revolution. It therefore follows that asthe record returns to the magazine the cam recess 53 of the cam 53 will be positioned diametrically opposite the cam follower 44 so that the detent 33 will remainin engagement with the rack 32 and maintain the carriage against movement relative to the magazine 4. The slots I6 are thus maintained in cooperative alignment with the record just returned to the magazine as the cam shaft 29 begins its second revolution. During this movement of the cam shaft 29 during its second revolution the record previously positioned on the turntable will again be returned to said turntable in the manner hereinbefore described by the downward swinging movement of the arms 89, the operation of the positioning fingers 98 and HH and the downward swinging movement of the movable track 20.

As the record is thus brought into cooperative engagement with the-turntable C the second time the cam shaft 29 will have completed 180 of its second revolution while the cam 53 will have been rotated another quarter of a'revolution or atotal of two hundred seventy degrees from the start. It will thus be seen that the cam follower 44 will remain in contact with the peripheral surface of the cam 53 while the switch operating pin 66 connected with cam 53 will have moved from the position illustrated in Figure 17, diametrically opposite the cam follower 44, threefourths of a revolution into engagement with the tion thereof, the switch I45 will be closed in the manner hereinbefore described. Inasmuch as the switch 69 is then in the open position the electro-magnet 82 will remain de-energized providing the circuit through said electro-magnet is not closed by the co-action of the contact arm I25 corresponding to the record compartment 8' from which the record on the turntable was received and the contact member I 33 or by a manually operated switch I58 in the manner presently described.

When the electro-magnet 82 is thus maintained de-energized it will be obvious that the cam shaft 29 will continue to be operated by the drive shaft 1) so that instead of the record being permitted to remain on the turntable it is immediately lifted from the turntable by the action of the arms H4 and then returned to the compartment 8' previously occupied thereby in the magazine 4 by the record carrier arms 88. It will be observed that as the record is returned the second time to the magazine 4 said record will be again inverted by the action of the arms II 4 so that said record will be arranged with the sides thereof in the initial position initially maintained thereby.

As the first record E is thus returned to the magazine the second time the cam shaft 29 will have completed two complete revolutions since the beginning of the operation of the machine while the cam 53 will have completed one revolution. The cam follower 44- will therefore be in registration with the cam recess 53' so that the detent 33 will be brought out of holding engagement with the rack 32 by the co-action of the springs 36 and 4| upon the detent 33 and bellcrank lever 39. When the rack 32 is thus re leased the carriage is free to be manually operated as desired to bring the slots I6 into predetermined relation with any of the records contained in the magazine 4 so that as the record operating mechanism is again actuated a second ceeding the one previously engaged thereby andv then to move the carriage rearwardly one tooth space to bring the slots I6 into cooperative alignment with the next succeeding record in the magazine 4. As the slots I6 are thus brought into cooperative relation with the .next succeeding record this record will be brought into playing position upon the turntable C in the manner hereinbefore described for the first record for playing. -.After this second record has been played it willthen be automaticallyreturned to the magazine with the sides thereof facing in the reverse order from that previously occupied thereby. After this secondrecord has been returned to the magazine it is immediately moved from said magazine back onto the turntable after which the record may be immediately returned to the 1 2,148,250 magazine if it is not desired to'play the same on the opposite side, from that previously played or it may be caused to remain upon said turntable to be played as desired.

If it is desired to playthe record on the second side this maybe accomplished by the operator moving the contact arm I corresponding to t the record selected to the horizontal position so that as the carriage is moved to bririg the slot I6 thereof into cooperative alignment with the compartment 8' from which the record to be played was'obtained, the circuit throughwire I41 will be closed by the engagement of said contact arm with the contact member I33 mounted on the carriage I2. I

When the switch I45 is closed by member 12 the circuit through the electro-magnet '82 will be completed although the switch 69 is maintained in the open position. This is due to the current passing from the conductor I40 through the magnet 82 and then from the wire I46 and switch I45 to the wire I41 after which the current passes through the wire I60, contact member I36, plate I35, contact member I38 to the contact arm I25 and thence through the shaft I28 to wire IGI, to wire I49, switch I50 and wire I5I to the negative conductor I4l. As the electro-magnet 82- is thus energized the clutch member 18 will be moved out of engagement with the clutch element I6 into engagement with the clutch element TI, thereby disconnecting the cam shaft 29 with the motor B and connecting the turntable shaft c with said motor for operating the turntable. As

theturntable is thus being operated by the motor B the tone arm may again be brought into engagement with'the record thereon for playing. After the record has been played said record may be automatically returned to the compartment of the magazine previously-occupied thereby by the operation of the record lifting or reversing arm I H4 andrecord carrying arms I88 hi the manner hereinbefore described.

As the second record is thus brought into the magazine compartment the second'time the carriage I2 will again be released by the detent 33 so that said carriage is free to be manually operated if it is desired. to effect the playing'of other than the next succeeding record. If the records in the magazine are to be played in succession the carriage I2 is only automatically moved rearwardly one magazine chamber space as each record is .placed into the magazine the second time.

It will now be understood that during the operation of the machine or during the playing of a record, any one of the records in the magazine 4 may be rearranged as to the :order thereof or replaced by another record. Furthermore, any previous setting of any one of the contact control arms or any number thereof may be changed whereby a record contained in the magazine or on the turntable or any number of records contained in the magazine may be caused to be played on one or on both sides as desired. when it is desired to play all of the records contained in the magazine on both sides the operator may set the machine by two methods to automatically accomplish this result. One, by moving all of the contact control arms I25 to the horizontal operative position so that they will be successively engaged by the contact member I33 as the carriage is brought into successive registration with the records in the magazine.

atone end with the wire I41 and at the other end with the wire IGI. When the switch I58 is,

thus'cl'osed the electro-magnet 82 will be energized each time the switch I45 is closed as the record is positioned upon the turntable C, irrespective of whether switch 69 is closed or open, so that the motor B will be. disconnected from the cam shaft 29 and operatively connected with the turntable C for rotating said turntable.

when the switch I58 is thus closed and the switch 69 is opened by the member 66, current will pass from the positive conductor I40 through the electro-magnet 82, wire I46, switch I45, wire M1, to the wire I59 and thence through, the switch I58 to the wire ISI and back to the negative conductor I through the wire I49, switch I50 and wire I5I. I

In addition to the above described mechanism and the operation thereof, I have provided a switch 68 which has one contact member as 61 thereof electrically connected with the positive conductor I40 at one side of the switch I42 by an extension I40 of said conductor. The other contact member as 81 of the switch 68 is, con-" nected by a wire I63 with the positive conductor I40 at the opposite side of the switch I42. This switch 88 as indicated in Figures 12 and 17 is mounted in such relation to the .cam 53 that the switch operating member 68 connected with said cam will maintain the switch in the open position only when the cam recess 53 is in reg istration with the cam follower 44. It will thus be seen that after the record changing apparatus is caused to operate by the closing of switch I42 the current for said operating mechanism will continue to be supplied thereto although the manually controlled switch I42 is open until such time as the switch 68 is again opened by the member 86 which will-not occur until the cam 53 has completed itseycle of movement. This results in each record being returned to its allotted compartment in the magazine the second time before the machine ceases to operate, even though the switch I42 is opened at any time between theiirst removal of a record from the magazine and the replacement thereof in the magazine the second time.

It therefore follows that when the record,

changing apparatus is rendered inoperative both '.of the switches 88. and I42 will be in the open position at which time all of the records will be in the magazine and they will be arranged with the sides thereof in the same order as when manually placed therein.

- Although I have shown and particularly described the preferred embodimentof my invention, I do not wish to be limited to the exact construction shown, as various changes both in the form and relation of the parts thereof may readily be made without departing from; the spirit of the invention as set forth in the appended claims.
