In the drawings there is shown, by way of illustration, a preferred form oi the invention. In this iorm the entire operating mechanism for rotating the turntable and manipulating the records and pickup arm is mounted upon a deck plate Iii which may be secured in a cabinet. not shown. in any well known manner. In Fig. 1 there is shown the playing turntable II, the storage magazine 32 containing therein a stack of records including small records It and larger records II. A record 3! ot the small size is shown during transier from the magazine to the turntable for playing.

Powerdricc An electric motor 36 (see Fig. 2) is supported upon the under-surface or the deck plate 30 and continuously drives a spindle 31 by means of gears, not shown, contained in a housing 88. The spindle 81 supports the turntable II in the usual manner. The motor 38 also drives a stub shaft It by means of other gears contained in the case 38. The shaft 39 has secured thereto a sprocket 40 which carries a sprocket chain ii for driving a sprocket II which runs ireely on a cam shaft 3. The cam shaft 43 has splined thereto a clutch 44 carrying teeth engaging .with similar teeth upon the hub of the sprocket 42. A compression spring 45 normally presses the clutch ll into engagement with the mating teeth and when the clutch is so engaged, the motor 36 drives the shaft ll. The cam shaft 43 is fitted with a pinion l6 driving a gear 41 mounted upon a second cam shaft It. The pinion l6 and gear 41 are proportioned to provide one revolution of shaft 48 for each two revolutions oi the shalt 43. The shaft 43 carries a plurality of cams, to be hereinafter described, which control the various movements which take place in a single recordchanging cycle including the moving of a record from the turntable to the magazine and the moving of the same or another record from the maganlne to the turntable. The shaft 43 makes one revolution for each such cycle of operation and may. therefore. be known as the "one-cycle" cam shaft. The shaft ll makes one revolution for each two cycles and operates mechanism which determines whether the same or a diilerent record is to be returned to the turntable for playing. This shaft, therefore, may be known as the "two-cycle" shaft.

Clutch operating mechanism The clutch 44 is placed into operative position by the momentary actuation of a solenoid 49. This actuation takes place automatically upon completion of the playing of a record and may be accomplished by any of several well known forms of apparatus-as for example, that shown in copending application of Ralph R. Erbe, Serial No. 10,441, flied March 11, 1935. The solenoid 49 is provided with a plunger 50 having thereon a shoulder ii against which there abuts a compression spring 52 normally urging the plunger to the right in Fig. 2. During playing of a record, the plunger is in the position shown in Fig. 20 and in that position a pin 53 pivotally mounted upon the plunger engages a groove 54 in the clutch member 44. Said pin rests against a hook-shaped lever 55 (see Fig. 11) which serves to hold the pin and the clutch member 44 in the disengaged position. The lever 55 is pivotally mounted at 56 upon a bracket 51 formed upon the undersurface of'the deck plate ill and is retained in position by a tension spring 58.

Upon actuation of the solenoid 49, the plunger is drawn to the left as shown in Fig. 2. The pin 53 is thereby withdrawn from its engagement with clutch 44 and lever 55 and is drawn by a tension spring 58 against a stop 60, the end of said pin resting against the upright portion of lever 55. The removal of the pin permits clutch 44 to move under the influence of spring 45 into operative engagement with the mating teeth and initiates the movement of the two cam shafts 43 and 48. During this movement, a cam 6i mounted upon the one-cycle cam shaft 43 engages the tip of lever 55 and moves the same to the left in Fig. 11 sufllciently far to permit the pin 53 to slip into its engagement with the groove 54, this movement being caused by the action of spring 52. At the completion of one revolution of shaft 43, the tip of lever 55 reaches a shoulder 62 on the cam ill and slips into the position shown in Fig. 11 under the influence of spring El. In this movement, the pin 53 is operated to withdraw the clutch element 44 from its operative position and thereby to stop the movement of the cam shafts 43 and 48.

Pickup arm elevating and lowerina mechanism The first operation performed by the movement I of the one-cycle cam shaft 43 is the elevation of the stylus from the record. In Figs. 1 and 18 the pickup arm BI is shown. The arm. carries the usual pickup mechanism 84 and stylus 65 for engaging the record for reproduction. The arm BI is pivotally mounted at 86 upon a bushing 61 which is mounted for pivotal horizontal movement on the deck plate 38. On the undersurface oi the arm 83 there is provided a plate 88 beneath which there is located a vertical pin 89 slidably mounted in the deck plate (Figs. 7 and 18) The lower end of the pin 69 rests upon an adjustable stud Hl carried on one end of a lever H, said lever being pivotally mounted upon a bracket I2 secured to the undersurface of the deck plate II. The opposite end of lever H is provided with a pointed cam follower ll following a cam 14 carried upon the one-cycle cam shaft 48.

The shape of the cam 14 is such that the follower lt is pressed downwardly as soon as the rotation of shaft 43 commences. The pin II is thus pressed upwardly to elevate the stylus from the record. For this purpose, the plate 68 is sumciently elongated so that it may rest upon the pin 69 in either the innermost or outermost positions of the stylus. Due to the shape of cam 14, the stylus remains elevated throughout the remainder of the record-changing cycle and is lowered into position upon the record at the completion of said cycle. It will be noticed from Fig. '7 that in the lowering of the stylus, the pin 69 drops out of engagement with the plate 68 so that there is no frictional engagement therewith during the playing of a record.

Record elevating mechanism After the stylus has been raised, the next operation performed by the rotation of the one-cycle cam shaft 43 is the elevation of the record just played from the turntable to clear the centering pin formed by the upper end of the spindle 31. This is accomplished by means of a pair of elevators 15 positioned upon opposite sides of the turntable 3| (see Figs. 1 and 8). Said elevators are provided with side guides I6, properly spaced to include a record of the larger size, and with an upper surface 11 adapted to support records of this size. They are also provided with a lower surface 18 for supporting the smaller size records, the boundary between the surfaces 11 and 18 being properly spaced to provide guides for the latter size of record.

The elevators 15 are mounted upon spindles l9 vertically slidabie in the deck plate 3|] and are also provided with guide pins 80 sliding through other openings in said deck plate. The lower ends of the spindles I9 rest upon adjustable studs Bi carried upon levers 82 which are pivotally mounted upon brackets 83 formed upon the lower surface of the deck plate 30. The levers 82 rest upon earns 84 carried by the one-cycle cam shaft 43. Said cams are provided with fiat spaces 85 upon which the levers 82 rest during the playing of a record. In this position, the elevators are whereupon the elevators are again lowered by' the cams to place the record upon the turntable for playing. The elevators reach their lowermost position simultaneously with the completion of a single revolution of the one-cycle cam shaft 43.

Mechanism for moving records from the elevators to the magazine The movement of the records from the elevators to the magazine is accomplished by an arm 86 (see Fig. l.) The return movement of the records from the magazine to the elevators, a detailed description of which is given under a later subhead, is accomplished by an arm 81. The arm I8 is mounted upon the upper end of a pin 88 pivotally mounted in the deck plate III while the arm 81 is pivotally mounted for vertical movement upon a pin It similarly mounted upon said deck plate. Each of said pins 88 and 88 has secured thereto at its lower end an arm 90, said arms supporting a slide 9| having slotted openings 82 embracing the pins 88 and 88 which, therefore, serve as guides permitting horizontal sliding movement of the slide ii. The arms 90 are provided with pins ll sliding in slotted openings 94 in the slide II. By this construction it will be apparent that movement of the slide ii to the right will move the levers 86 and I! in unison in the same direction while a movement of the slide ii to the left will move said arms to the left.

The slide BI is provided with a yoke-shaped depending member 98, best seen in elevation in Figs. 3 to 6, inclusive, and in section in Fig. 10. Sold member 8! is provided with inturned flanges 96 and 91 adapted to engage a cam 98 carried by the one-cycle cam shaft ll. This cam is so shaped that it engages the flange 88 and moves the slide to the right at the proper time to bring the end of arm 86 into engagement with a record which has just been elevated from the turntable and to move the record to the magazine. In this movement the record is guided, if it is a large size record, by the guides III, and, if a small size record, by the guides formed by the boundaries between the surfaces I1 and I8. Upon leaving the elevators IS. the records are guided by members 9 which are formed in substantially the same manner as the elevators and, similarly, provide guides for both sizes of records.

At the time of delivery of a record to the magazine, the latter may be either in the position shown in Fig. 4 or in that shown in Fig. 5. In the position shown in Fig. 4, the end of arm 88 enters the confines oi the magazine beneath the portion IIII thereof so that the record is placed well within the magazine. Similarly, with the magazine In the Fig. 5 position, the arm' enters the confines thereof through a notch Ill shown only in Fig. 12. During the latter part of this movement, a downwardly extending portion III! of the slide II (see Figs. 2'and 19) engases the end cf'a spring-pressed stud Ill slidably mounted on a boss I!!! on the bottom of the deck plate and in so doing, compresses a spring I". At the completion of said movement. a shoulder ,III'I onthe cam 90 reaches the end of the flange 86 (see Fig. 4! whereupon the slide '9I is permitted to move slightly to the left under the influence of spring III. and thus promptly removes the end of lever 88 out of the confines oi' the magazine to permit manipulation of the magazine hereinafter described.

Magazine manipulating mechanism The record storage magazine is shown in perspective in Fig. 12 and consists of a frame having side walls I" about three of its sides, a cross plate I" forming with a lag III a support for a group of records when the-magazine is in the horizontal position shown in Fig. 12; a pair of end plates III andapair of partition plates 2. The magazine is fitted with a pair oi trunnions H3, one of which is pivotally connected to. links H4 and Illfsee Figs. 1, 2 and 15). The link I is pivotally mounted on an upstanding bracket H8 carried by the deck plate I and the link I" is pivotally connected to one end of a lever III which in turn is pivotally connected to a bracket illsecuredtotheundersnrface'ofthedeck plate ii. The lever II'I rests upon a cam Iii-carried by the two-cycle cam shaft ll.

'lhesecondofthetrunnions'iiIissimilarly' plvotaliy mounted on links III and III. The link I" is pivotally attached at its other end to a bracket I22 carried upon the W surface of thedeckplateandthelink lliispivotallyoonnectedtoalever I28 pivotallymounted on a bracket Iflsecured'to the \mdermrfoee of said deck plate. The lever I23 rests upon a cam III carried upon the two-cycle cam shaft 48, said cam being similar to cm Hi. This construction supports the record magazine upon the cams HO and III and it is obvious that the rotation of the two-cycle cam shaft 48 may raise and lower the magazine. To counterbalance a portion of the weight of the magazine, there is provided a tension spring Ill secured at one end to the deck plate II and at the other end'to a downwardly extending portion III of the lever I II. A similar spring may be attached to the lever I23 if necessary.

During the playing of a record. the magazine stands in the position shown in Fig. 6 with the group of records 3! in a vertical position resting upon the side walls II. of the magazine. During the receipt of a record from the turntable. the magazine is moved to a horizontal position as shown in Figs. 4 and 5 with the closed side of the side walls toward the turntable. During the removal of the record from the magazine for playing. the magazine assumes the position shown in Fig. 3 with the open side toward the turntable. The mechanism for tilting the magazine to the several positions includes a crank arm in mounted upon the one-cycle cam shaft ll and having its outer end pivotaily connected to a link I28. The opposite end of the link I" is pivotally connected to a cam plate III which is in turn pivotally mounted upon a pivot pin Iii, which also serves to connect the links III and I. A T-shaped member I" is secured upon one of the trunnions H3 and carries a roller III eng in the edge of the cam plate I30. The cam plate also carries pins I adapted to engage the head portions of pletion of playing of a record, moves the cam plate ill to the position shown in Figs. 4 and 5, Inwhich position the roller lllis raised by the cam plate to move the magazine to the horizontal record-receiving position. After the recelpt of the record, further rotation of cam shaft It moves cam plate Ill toward the position shown in Fig. 3. In this movement one of the pins Ill strikes the head of the T-shaped member In as the roller III reachu the recess I". It thereby tilts the T-shaped member and insures that the roller enters the recess to return the magazine to the vertical position. This movementicontinues beyond this position, however. to the position shown hills. 3 in which the roller ilihas ridden onto the lefthand portion of the plate Ill, cousins the magazine to the horizontal podtion for removal of a record there- The completion of the rotation of cam Itwillbeseenthattheflltingofthemagazine durirtherecelptandremovalofarecordiscon theone-cyclecamshaftllwhilethe I88 between the plates I II and H2 is at the level of the guide members 88 and thus the returning record is placed in that compartment. The remainder of the records stored in the magazine are in the larger compartment I81 between plates I88 and H2. In the reversal of the magazine to the Fig. 3 position, the record in compartment I88 is supported by lugs I88 and is brought into the uppermost position in the magazine. Since the arm 81 which removes records from the magazine always takes the uppermost record, as will be hereinafter described, the same record is returned to the turntable for playing in the reversed position.

When the second side of the record has been played and the record is again returned to the magazine, cams H8 and I25 on the two-cycle cam shaft have made a half revolution and are now in the position shown in Fig. 5, permitting the magazine to drop sufllciently low for the record to pass over the side wall I88 thereof and to be deposited upon the group of records in the magazine compartment I81. In the next reversal of the magazine to the Fig. 3 position, the record just played becomes the lowermost one in the group and a new record is removed from the top of the group for playing.

Mechanism for removing records from the magazine The removal of records from the magazine is accomplished by means of arm 81. This arm is provided with a side extension I88 adapted to rest upon the top of the uppermost record in the magazine and with a downward extension 8 adapted to engage the edge of said record. During the movement of the slide 8| to the right, the arm 81 is raised about its pivotal mounting upon the pin 88 to clear the magazine. This is accomplished by means'of a member Ill mounted for vertical movement in the deck plate 38 and having an arcuate portion I82 upon which the arm 81 may rest. The member III is provided with arms I88 embracing the pin 88 to prevent the member from rotating. The lower end of the member Ill is supported upon an adjustable stud I (Fig. 13) carried on the end of a lever Ill which is pivotally mounted on the bracket I28 and which rests on a camv I48 carried by the onecycle cam shaft 43. When a record has been returned to the magazine with the arm 81 upraised to clear the magazine and the magazine has been reversed to the Fig. 3 position, the cam I88 acts to lower the arm 81 to permit the same to rest upon the uppermost record in the magazine, whether said record is in the small compartment I88 or in the larger compartment I81. At this time the cam 88 is in the position shown in Fig. 3 and further rotation thereof brings the same into engagement with the flange 81 to commence movement of the slide 8| to the left. This movement moves the arm 81 to the left carrying the topmost record from the magazine.

Mechanism for centering records of difierent sizes on the turntable It is obvious that for records of different sizes the travel of the arm 81 toward the turntable must be variable in order to provide accurate centering of the record over the pin 31. This is accomplished by providing on the cam shaft 48 a cam II! which may be moved along said shaft into and out of position to engage the flange 81. This cam has the operating portion thereof of greater radius than the corresponding portion of cam 88. When cam I" is in the operative position engaging flange 81, it controls the movement of the slide 8| to cause the arm 81 to travel the proper distance to center the smaller size of record. When the cam I" is withdrawn to the position shown in Figs. 9 and 10, it does not engage the flange 81 and the movement of arm 81 is then controlled by cam 88 to center the larger size of record.

For controlling the movement of cam I" on the shaft 88 there is provided a roller I48 mounted upon a lever arm I48 pivotally mounted by means of a small pin ,Iill upon a larger pin l8l carried upon a bracket I52 supported on the undersurface of the deck plate 88. The roller I48 is so positioned that it may be engaged and pressed backward to the position shown in Fig. 9 by the larger size of record but will not be engaged by the smaller records. The said roller is held in proper position by a tension spring I58. When the roller is pressed outwardly to the Fig. 9 position, the lever I48 engages the upper end of a lever I which is also pivotaliy mounted on the pin iii. The lower end of said lever engages a groove I88 in the hub of the cam I41. The cam I" is slidably mounted upon the shaft 48 and is prevented from rotating thereon by a pin I58 mounted upon the cam 88 and passing through a suitable opening in the cam I". Said cam may, therefore, be considered as splined to shaft 88.

In the operation of this portion of the device, the passage of a large size record toward the turntable presses the roller I48 outwardly and, through the lever I54, moves the cam I" out of its operating position, thus permitting the travel to be controlled by the smaller cam 88. After the return of the record to the magazine and before the removal of the next record, a cam surface I81 on the hub of cam Il'l engages a. pin I88 carried by the bracket I88 and returns the cam Ill to its operative position. If the next record moved to the magazine is the smaller size record, the cam remains in that position and controlsthan the flange 81 so that it cannot be engaged by cam I41. Thus the return of records of either size to the magazine is controlled by cam 88.

Mechanism for horizontal movement of pickup arm The return of the pickup arm to the starting point for the two sizes of records is accomplished by the left-hand movement of the slide 8! and is, therefore, under the control of cam 88 when the large size record is moved to the turntable and under control of cam I" when the smaller size record is moved to the turntable. For this purpose. there is mounted on the lower end of the bushing 81 a clamp Ill having a lever arm I88 and a pin "I carried thereby. The lever arm I88 projects into the path of a downwardly turned portion I88 of the slide II and is engaged thereby in the right-hand movement of said slide at the beginning of the record-changing cycle. This movement swings the pickup arm to the left in Fig. l to a point beyond the starting point of either the large or mail record.

At the return of the slide 8| toward the end of the record-changing cycle, the pin I is struck by a spring-pressed stud I88 mounted upon a downwardly turned portion Ill of the slide 8|.

If the record being transferred is a large size record, the cam 98 limits the travel of the slide to bring a pit or hollow I65 in the plate 68 into engagement with the upper end of the stem 60. This pit is so placed that the stylus, when lowcred, will accurately engage the large size record at its starting point. It the record being transferred is a small size record, the slide moves further to the left under control of cam Ill and moves the pickup arm sufliciently to bring a second pit iBB into engagement with the end of the stem 89. In this position, the pickup arm is accurately lowered to the starting point of the smaller size record.

Power equalizing device It will be noticed that the trunnions III on the magazine are not located at the center of gravity of the magazine and the records therein. For this reason, the movement of the magazine from its vertical position to a horizontal position requires a relatively large force, whereas the movement from the horizontal to the vertical might be accomplished by gravity. To equalize the forces involved and to assist the motor in raising the magazine there is provided mechanism shown in Figs. 16 and 1'7 and also appearing in Fig. 2. r This mechanism includes a cam l8! mounted upon the one-cycle cam shaft 43 and engaging a lever I68 pivotally mounted upon a bracket I69 secured to the undersuriace of the deck plate 30. The opposite end of the lever is connected to a heavy tension-spring Ilil secured to the undersurface of the deck plate 30.

The upper suriace of the lever IE8 is provided with a notch ill andsaid lever has secured to one side thereof a plate 112 forming a continuation of the upper surface in the region of said notch. The com IBI has one end thereof formed with a recess I13 which permits the end oi the com to enter the notch Ill, the remainder oi the carzn being of sufiiclent width to engage the plate In the playing position of the mechanism, the recessed end of the cam engages notch I'll as shown in Figs. 16 and 1'7 and thus holds the record-changing mechanism against undesired movement while the clutch 14 is disengaged. Upon the commencement oi rotation, the end of the cam leaves the notch and the lever I68 is pressed against the portion ill of the cam by spring no. This portion of the cam is so shaped that the spring pressure tends to rotate the shaft 43 in the direction in which itis already moving and thus assists the motor in raising the mags zinc from the vertical to the horizontal position. when this position has been reached and the magazine again moves toward the vertical p051- tion, the portion I15 of the cam is riding on the lever I68 and the plate I12, forcing the same downwardly, extending the spring Ill and impeding the rotation of shalt ll. The opposite point I16 oi the cam reaches the lever I" as the magazine again reaches the vertical position but since this point is the full width oi the earn, it

does not enter the-notch H l. During the succeeding movement of the magazine to the horizontal record-removing position, portion I" of the com acts to assist the raising of the magazine and during the next downward movement thereof, portion I18 retards said movement. Thus, at each movement of the magazine from horizontal to vertical, a certain amount of energy is stored in the spring illl and is later returned to this system to assist in the subsequent movement from vertical to horizontal.
