Patented Aug. 12, 1930 i JOSEPH D. FE HER, OF MIAMI, FLORIDA SOUND-RECORDING APPARATUS Application filed February 23,1926. Serial No. 90,130.

This invention relates to sound recording apparatus and it is an object of the invention to provide an apparatus of this kind wherein the operation isundercheck control and which provides an effective mechanism whereby a spoken messa e may be recorded upon a disc or record ank, the blank or disc being automatically discharged.

Another object of the invention is'to pro- 30 vide an apparatus of this kind operating under check control in an automatic manner to record and to deliver in the form of a record disc or the like, a message or other sound and which disc or record member is adapted 5 to be transmitted throu h the mails or otherwise transported whereby is obviated thenecessity of writing a letter or utilizing the services of a public stenographer as is now generally done by salesmen and other persons whose duties require them to travel and to make reports daily or at other periods of time.

' It is also an ob ect of the invention to prov vide an apparatus of this kind comprising a turn table having associated therewith a magazine for record blanks or discs, together with means under control of a coin or check for causing a disc record blank to be delivered from the magazine in proper position upon the turn table and to efiect the requis! its rotation of the table, and to bring a sound recording mechanism. in working contact with the record blank on the table.

An additional object of the invention is to provide an apparatus of this kind compriss5 ing a table adapted, under the influence of a coin or other check, to be rotated for a predetermined period of time together with automatic means functioning during the period the apparatus is in operation to properly po- 40 'sition a recording disc or other member upon the table and to bring a recording mechanism in requisite engagement with such disc or member and wherein the disc or recording member is automatically discharged or eject- 'ed when the apparatus becomes. inoperative. The invention. also has fora-an object to rovide an apparatus of this kind adapted to e placed in public places, such as hotel lobbies and the like, and which provides means 0 whereby a message or the like may be readily of the apparatus are caused to operate in proper sequence; '65

As disclosed in the accompanying drawings, C denotes a cabinet in which my recording apparatus is housed.

Above its lower end, the cabinet C is intersected by a horizontally disposed floor 1 95 upon which is mounted adjacent to the rear wall 2 of the cabinet an upstanding bracket 3 providing amounting for the lower end portion of a tubular shaft 4. 'This shaft 4 is upwardly and forwardly inclined and W9 the upper portion of the shaft 4 is disposed through and rotatably supported by a cross member 6 interposed between the side walls of the cabinet. The lower end portion of the shaft 4 has fixedthereto a gear 7 meshing with a gear 8 rotating with the larger gear 9 supported by the upstanding brackets 10 carried by the floor or partition 1. This gear '9 meshes with the pinion 11 constituting a hub for a larger gear 12 also rotatably supported by the brackets 10 and this gear 12 is in mesh with the pinion 14 carried by an end portion of the drive shaft 15 comprised in the motor M of an electrical type; When the motor M is energized, the shaft 4 will be caused to rotate at a predetermined speed.

The upper end portion ofthe shaft 4 is suitably affixed, as at 16, to the axial center of the turn table 17, said table being provided with a central opening 18 in continuation of the bore of the shaft 4. This table 17 is snugly received within an opening 19 provided in a runway B. This runway extends from the inner or discharge end portion of a magazine A to a delivery slot or opening 20 provided in the front wall 5 of the cabinet C at a point below the table 17. The runway or chute R is continued outwardly beyond the front wall 5 of the cabinet C by an apron 21 terminating in an upstanding flange 22. This flange 22 provides a stop for an ejected record blank.

The magazine A comprises a horizontally disposed semi-cylindrical trough suitably supported within the upper portion of the cabinet C and preferably adjacent to the front wall 5 by the arms 23 or otherwise. This magazine A is adapted to carry a plurality of discs D or blanks and which are adapted to be intermittently fed toward the upper or receiving end portion of the runway R.

As is particularly illustrated in Figures 3 and 4, the upper portion of the runway R is spaced from the adjacent end of the magazine A a distance substantially equal to the thickness of a disc D whereby the forward movement of the disc pack or cartridge is limited to permit only a single disc to be received at a time within the runway R for initial delivery upon the table 17.

The disks or blanks are shifted longitudinally along the trough A by means of a follower 24 which is approximately circular in form and has an arm 25 which is supported by a slide 26 which is grooved or channeled to receive guide rails 28 mounted within the cabinet C. Thus the follower 24 is supported for movement toward or from the discharge end of the mazagine A. Y

The arm 25 above the follower 24 but below the block 26 has secured thereto an end portion of a. flexible member 29 which extends inwardly above the magazine A and over a guide pulley 30 positioned above the receiving end of the runway R. The member 29 ex tends downwardly from this pulley 30 and is wrapped around a pulley 31 suitably supported for rotation. The member 29 extends downwardly from this pulley 31 and to its free or lower extremity has secured thereto and suspended thereby a weighted member This weighted member 32 operates to automatically effect the desired movement of the follower 24 toward the discharge end of the magazine A to effect the desired discharge from the magazine of a disc D. This movement of the follower 24 is effected intermittently and, as herein disclosed, the desired operation is accomplished by having fixed to an end portion of the pulley 31 a ratchet wheel 33 which is positioned between the arms 34 of an anchor escapement 35. This escapement 35 is supported for swinging movement, as at 36, and is provided at its pivoted portion with the extended arm 37 which is adapted to be swung at predetermined intervals to effect the requisite oscillation of the anchor escapement 35 whereby the desired intermittent movement of the follower 24 is permitted under the influence of the weighted member 32. It is believed to be obvious that the pulley 31 is normally held against rotation by contact of one of the arms 34 with the ratchet 33 but which is normally urged toward such ratchet by the weight of the arm 37. How-' ever, to further assure intermittent movement of the arm 37 the expansible spring 38 is provided contacting with the arm 37 from above andtheextentofmovementofthearm37 in such direction is limited by contact with the adjustable stop 39. This stop 39, as herein disclosed, comprises a shank threaded through a foot 40 carried by an end portion of a rod 41 extending downwardlyfrom a supporting bracket 42. The expansible member 38 hereinbefore refered to is interposed between the arm 37 and the support 42.

Movement of the arm 37 in the opposite direction is accomplished, as herein disclosed, by the electro-magnet 43 depending from the bracket 42 and which is interposed in an operating circuit comprising the conductors a and b in connection with a suitable source E of electrical energy. In communication with the chute 46 above the contact members 44 and 45 is a coin slot 47 provided in the front wall 5 of the cabinet C. The contact member 45 is supported for swinging movement in a direction toward and from the contact memher 44 and is normally held in close proximity to the contactmember 44 by the normally extened core 48 associated with the solenoid 49. As particularly illustrated in Figure 2, the contact members 44 and 45 extend down wardly and convergently but are at all times in spacedrelationbut when a coin or other meductors a and 5 resulting in the energizing of the magnet 43 with the resultant delivery of a disc lD upon the runway R.

Also interposed betweenthe conductors a and b is an electr c-magnet 51 depending from a cross strip 52 suitably supported within the cabinet 0 at a pointbelow the lower portion of the table 17. The magnet 51 is simultaneously energized with the magnet 43 and when energized the magnet 51 imposes upward movement to the rod 53 slidably disposed through the cross strip 52 and a further cross strip 54 suitably supported below the strip 52. The portion of the rod 53 above the cross strip 52 is enlarged to rovide a head 53 said head 53 having contact with the cross strip or member 52 from above to limit the downward movement of the rod 53. Extending upwardly from the head 53 are the normally separated spring contacts 55 which, when the head 53' is in its lowermost position, are below the upper surface of. the

table 17 in order to Older no hindrance or obstruction to the passage of a disc D from the table 17 for delivery or discharge through theopening 20.

These contacts 55 are carried upon an arouate stop or record blank rest 56 and project beyond the middle of this rest or stop 56. The ends of this rest are provided with outstanding lugs 99 and, as shown in Figure 5, the floor of the runway, which is cut out to receive the turntable 17, is also out out to permit the outward movement or retraction of these lugs 99 and of the pair of contacts 55, these contacts being disposed at the middle of the arcuate support 56, When the rod 53 is in its projected positiomthese contacts 55 are projected beyond the face of the turntable 1?, as are the lugs 99, so that as the disk or record blank D travels downwardly along the runway R, the disk will be stopped when superimposed upon and concentric with the turntable.-

As a disc D comes in contact with, the vuppermost contact member 55 it will force the contact members against each other closing a circuit through the shunt line 0 interposed between the conductors a and ,5. interposed in this line 0 is ,an electro-ma net 57 sup: ported by the upper portion of t e bracket-3. -When energized, the electro-magnet 57 imparts upward movement to a rod 58 disposed through the tubular shaft 4 and when in its osition b a retractile spring 60 interposed etween t e lower end of the rod 58 and an outstanding arm 61 carried by the bracket 3.

-It is also to be vunderstood that the rod 53 a second finger 67 carried by the foot 59 momentarily closes a switch 68 interposed in the circuit 6 also in multiple with the circuit comprising the conductors a and 0. Also interposed in the circuit e is an electro-magnet 69 which, when energized, releases a latch 70 from the upper portion of a horizontally swinging frame F permitting the stylus of the sound box 71 to come into proper engagement with the peri heral portion of the disc Dupon the table 1 The frame F has its lower portion pivot-- ally connected, as at 72, with the partition or fioorl and the sound box "Z1 is operatively engaged with the threaded portion 73 of the shaft 74,. This shaft 7% is rotatably supported by the side members 7 5 comprised in the frame F and one end portion of the shaft 7% is in driven connection by the gear train 76 carried by one of the side members '2 5 with a drive gear 77 carried by the shaft 78. This shaft '38 is rotatably supported by the lower portion of said side member 7 5 and the supplemental frame -member Y9. This member (9 is in parallelism with the side member 2' 5 just referred to and provides additional support for the gear train 7 6 and the adjacent end portion of the shaft T i, The

gear f '1 is constantly in mesh with the gear 80 keyed to the adjacent end portion of the shaft 15 for rotation therewith but having movement lengthwise thereof. A face of the gear 80 is provided with a clutch member 81 which interlocks with the clutch member 82 fixed to the shaft 15 when the frame F swings downwardly toward the table 17 whereby the shaft Wl is caused to rotate in a direction to move the sound box "(1 inwardly or vtoward the center or" the table 17 or more particularly the disc D superimposed thereon. "W hen the frame H which carries the gear 77 is swung outwardly, the clutch member 81 will disengage itself from the clutch member 82 under the influence oi the spring 83 carried by the hub portion of the gear 80 and having contact at the axial center of the adjacent this spring, therefore, acts to retract the gear 80 and the clutch member 81 in a direction away from the clutch member 82. When the frame F is swung outward, the gear wheel 77 will be retracted in a direction away from the motor M and the spring 83 will cause the gear wheel'80 to follow the gear wheel 77 in its outward movement until the clutch teeth on the member 81 disengage from the clutch teeth 82, thus disconnecting the wheel 77 from the motor.

Extending outwardly from the front wall 5 of the cabinet C is the mouth piece 84 which is in requisite communication with the sound box 71 through the medium of the interposed .flexible tube 85.

- over the applied disc D, a wedge member 86 enters between the side member 75 of the frame F remote from the gear train 76 and a fixed member 87 herein disclosed as suitably positioned within the cabinet C. This results in an upward or lifting movement being imparted to the frame F, bringing the stylus of the sound box 71 free of contact with the disc D on the table 17 and causing the latch 70 to engage the upper portion of said frame to again hold the same in inoperative position. As the frame F is raised or swung upwardly it tightens the endless cord or belt 88 dis osed around the pulley 90 fixed to the shaft 4 and also around a pulley 91 arranged to one side of and at the axial center of a larger pulley 92., This pulley 92 is rotatably supported by a swinging bracket 93 and is 'indriven connection through the medium of posed in the same general directionas the arm 86 is a second elongated arm 96. This arm 96 at its outer or free end portion is provided with a depending finger 97 which 0 crates to momentarily close a switch 98 a out the time the sound box 71 is returnedto its outermost or normal position.

' The closing of the switch 98 results in the energizing of the solenoid 49 retracting the core 48 and thus permitting the coin or check 50 between the contact members44 and 45 to free therefrom and thereby rendering the machine entirely inoperative until a further coin or check is deposited in the chute. The switch 98 is interposed in the circuit for the solenoid 49, said circuit being also in multiple withdthe circuit aiforded by the conductors a an '6.

, When the circuit is broken by release of the coin or check 50, the rod 58 is retracted as'is also the arm 53, thus releasing the disc B superimposed upon the table 17 and permitting the same to travel downwardly along the lower portion of the runway R and be discharged or ejected upon the apron 21 through the opening 20 in the front wall 5 of the cabinet C.

To further facilitate the functioning of the stop member 56, the extremities thereof are provided with the upstanding lugs 99. (See-Figure 7.)

A suitable pointer or indicator 100 is carried by the sound box 71 and is extended for visual access through the slot 101 in the front wall 5 of the cabinet C so that the person using the apparatus may readily determine wlhendthe recording operation will be comete p In order to facilitate the proper placement of a disc upon the table 17, I dispose transversely across the runway R immediately above the opening 19 a guide bar or strip 102 the under surface of which is preferably round in cross section upwardly from below, said bar 102 being spaced from the body portion of the runway R a distance slightly in excess of the thickness of a disc D. It will be seen that with this construction a single initial actuation consisting of the deposit of a coin in the coin slot 47 will cause the automatic delivery of a record blank to the chute or runway R, will cause the stoppage of this blank upon the turntable 17 and cause the projection of the rod 58 into engagement with the blank to center the same, that simultaneously-the motor will be energized, the latch holding the recording sound box ofii of the record blank will be released so as to bring the recording apparatus into engagement with the record blank, and simultaneously the recording apparatus will be caused to travel transversely across the blank toward the center thereof. When it reaches the center, the recording sound box will be automatically lifted from the blank and returned to its initial position and this will cause the breaking of a circuit to the motor and all the parts will be in their initial positions ready to record upon a new record blank. The operation of the device from the time that a coin is deposited in the coin slot until the time when the record blank has been delivered with the record thereon is entirely automatic.
