determined by the operator when putting the.

machine into operation.

In accordance with the present invention I provide an individual token for each recording in the phonograph. The tokens may be in the form of flat members so that they can easily be stacked one on top of the other. Each token may bear a number or title of the \recordin which it controls. be dispensed from one end of the stack one at a time. The dispensing means is correlated with the phonograph so that it operates periodically to dispense a token. Each token carries individual phonograph controlling means so that on dispensing a. token from the stack it actuates the phonograph so that the phonograph plays the corresponding recording.

In a preferred form of phonograph the recording to be played is determined by a displaceable member which is individual to an individual recording. The phonograph motor is put into operation when one of the displaceable members is displaced and the phonograph mechanism then cooperates with the displaced member to move out the corresponding recording and play the same. The displaceabie member may be returned promptly after the selection of the recording is determined. On such return the phonograph motor does not cease to operate because before the return a switch for the motor I has been closed by the operation of the motor and it remains closed until the end of the reproduction. If at that time no other displaceable member is in displaced condition the phonograph motor stops but in the event that there is another displaced member the phonograph motor continues to operate until the corresponding recording has been reproduced.

My token dispensing mechanism is preferably correlated with the displaceable members in such manner that the token dispensing means is operative when no bar is displaced and is inoperative when a bar is displaced.

My stack of tokens is placed in a magazine which may, if desired, be provided with a main switch which renders the selector operable automatically. In the preferred embodiment of my invention each token is preferably provided with switch actuating means which cooperate with a switch during the dispensing operation to give to multiselective phono 7.01am (Ol. 117-3535 The tokens are arranged to p 2 two trains of electrical impulses. The trains are separated by a time interval. The number of impulses in each train determines "which actuqating member will be actuated. Thus token 05 may have means creating three impulses and means creating eight impulses. The token for recording. 48 has means for creating seven impulses and then twelve impulses. The impulse creating means may suitably be projections on the tokens which actuate a stationary switch during the dispensing operation.

The invention will readily be understood from the following description of a preferred embodiment thereof taken in conjunction with the accompanyingdrawing, in which:

Fig. 1 is a plan view of my dispensing mechanism: I

Fig. 2 is an elevational view of the dispensing mechanism shown in conjunction with a wiring diagram and necessary elements of the phonograph; and

Fig. 3 is a side elevation of my dispenser as viewed from the dispensing side, which is the righthand side of Figs. 1 and My improved selector may be associated with many existing phonographs .so that it is unnecessary to disclose full details of a complete phonograph mechanism. In Fig. 2 I have shown a phonograph motor l0 which is arranged to be put into operation by any one of a plurality of selector. bars II. There may, for example, be 100 bars ll each corresponding individually to an individual recording on the phonograph, When any bar II is displaced upwardly as viewed in Fig. 2 by an actuator l2 the bar makes contact with a conductive strip I3 which is connected to a relay M. The relay I4 is connected to the ungrounded end of the secondary of a transformer l5 sothat the relay I4 is energized by the upward displacement of any one of the bars ll closing normally open switch l6 and opening normally closed switch l1. One side of the switch I8 is connected to the ungrounded side of the transformer IS, the other side of this switch being connected to the ungrounded terminal of the motor III. A switch I8 is arranged in parallel with the switch I6 so that the motor I0 remains in operation as long as either switch It or switch i8 is closed. .Switch I8 is arranged to be opened momentarily during the recording changing cycle of the phonograph so that it is opened after the reproduction of each recording. When the switch I8 thus opens and no bar II is in upwardly actuated position the phonograph motor ceases to operate until the selector moves "imam v lcit,totherishtandtothelettindeflnitely. Near' abar ll upwardly. vided on the phonograph i'or cooperating with an actuated bar II to determine the recording to be reproduced and after the recording has thus been determined and after the switch II has closed, means II controlled by the phonograph returns the controlling bar II to its initial position.

The actuator i2 is associated with stepping mechanism l9 which iscontrolled by the two trains of impulses to locate the actuator l2 beneath the bar I I corresponding to any two trains.

Abutment means II arepro 1 verses .the motor 23, so that reciprocation would After such location. an electromagnet 42. controlled by the stepping mechanism 49 is energized to project last said bar ll upwardly. The phonograph and the stepping mechanism may suitably .be that described and claimed in co-pending Patents Nos. 2,382,487 and 2,382,489, issued August 14, 1945, to Mahlon W, Kenney and Herman G. Jensen or Patent No. 2,425,974 issued August 19, 1947, to Marion R. Winkler. The last mentioned patent discloses a plurality of selector elements which correspond to the selector bars ll, abutment means corresponding to the abutment means 50, a pin controlled by the phonograph corresponding to the present plunger ii for returning the actuated selector element, and a phonograph motor controlling switch, which corresponds to the present switch Hi. In the last mentioned patent the selector members were actuated by individual solenoids. In the present application the selector bars H are actuated mechanically by an actuator i2 as in the two patents first referred to. Other phonographs are known in which control or recording selection is determined by the actuation of one of a series of members each'corresponding individually to a. recording, and it is to be understood that my invention is equally applicable to all such phonov have enough thickness so that each token can readily be dispensed separately from a magazine 2|, The magazine 2| may suitably consist of an open top box in which a stack of the tokens may be placed as shown in Fig. 2. The stack may rest upon supporting members 23 which may serve as guides for a slide structure 24. The front and rear walls of the magazine 2| terminate above the supports 23 so that the upper portion of the slide structure 24 may enter the lower part of the magaizne and may dispense the lowermost token 29 to the right as viewed in Fig. 1. The slide structure 24 carries rack teeth 25 which cooperate with a pinion 26 driven by gear reduction mechanism 26 which is actuated by a reversible motor 28.

One terminal orthe motor 28 is connected to the power line 29. The other power line .30 is arranged to be connected by switches hereinafter described to a reversing switch 3| which is conneoted by lines 32 and 33 to the motor. when the arm 34 of the switch 3| is in the full line position shown in Fig. 2.the motor is conditioned to drive the pinion 26 in clockwise direction as viewed in Fig. 2. Switch 3| may suitably be a toggle switch so that its arm 34 is snapped into the full line position shown in Fig. 2 by an abutment 35 on the slide structure 24 and is adapted to be snapped into the dotted line position shown in Fig. 2 by a projection 33'carried by the slide structure 24. It is to' be understood that it the circuit or the motor 28 were held closed the slide structure 24 would reciprocate to the right, to the continue indefinitely unless the motor-circuit is opened. Just when or an instant before the projection 3B throws the switch arm 34 into its full line position the projection 38 opens the switch 31 which is biased to closing condition. The pro-,

jections 33 and 33 are located so that the slide structure 24 is provided with a complete dispensing movement when moving to the right as viewed in Fig. 2 and is cleared irom the stack ot'tokens 23 in the magazine 2| during the lefthand movement of the slide structure 24. One side of the switch 31 is connected to the power line 30. The other side of the switch 31 is connected to the switch 3| and to one side of the switch H. The power line 30 and the other side of the switch I] are connected to a control switch 38. The switch 33 is preferably arranged so that it is closed by one or more tokens 20 located in the magazine 2 I. If desired the switch 33 may be arranged for manual actuation. As shown one of the leaves or the switch 38 carries an insulating pin 39 which projects upwardly through an opening 40 inone of the supports 23. One or more tokens 20 in the magazine depresses the pin 39 so as to close the switch 38. Each token 29 is provided with a longitudinal recess 4| in which are located two series or cam projections 42 and 43. These two series of projections are separated by a'space 44 so that two separate trains of ime pulses are provided for the actuation of the stepping mechanism [9. Each projection 42 is arranged to cooperate with an insulating pin 45 of a switch 48 so that this switch is closed once for each projection 42 or 43 passing out of the magazine 2|. The-switch 45 is connected by wires 41 to the stepping mechanism l9.

Each token 20 bears indicia 43 which indicates the individual recording to which it corresponds. Thus with a machine for 1.00 recordings the tokens may bear numbers from 00 to 99. The indicia 48 may include the title of the recording ,and other data. Token 05 may be provided with a train of three projections 42 and a train 01 eight projections 43, token 19 may have four projections 42 and twelve projections 43, and token 92 may have twelve projections 42 and five projections 43, to adapt the tokens for use with stepping mechanism shown in the aforesaid Kenney and Jensen applications. Adjacent the dispensing outlet of the magazine I provided a small table 49 to maintain the token being dispensed in substantially horizontal position until it is completely dispensed. The token may fall from this table into a suitable receptacle (not shown); V

The operation is as follows:

The operator selects the tokens corresponding to the recordings which he desires to reproduce. He stacks the selected tokens in the .order which he desires the recordings to be reproduced. 1

switch 88. Since the phonograph is out of operation no bar H is in its upward position and I consequently the motor 8| is put into operation.

its circuit being power line 88, closed switch 88, closed switch i'l, reversing switch 8|, and power line 28. The pinion 28 is driven in clockwise direction as viewed in Fig. 2 and the slide structure is moved to the right to dispense the lowermost token 20. It is to be noted that the initial movement of the slide structure 24' to the right closes the switch 81 and consequently the motor 8| continues to operate to cause the slide mechanism 24 to execute a complete reciprocating movement notwithstanding that during this movement the switch 88 or thevswitch I! may open. During the dispensing movement of the lowermost token two trains of impulses are communicated by the switch 48 to the stepping mechanism 19. These two trains result in the location of the actuator |2- beneath the pin ll corresponding to the dispensing token and the upward displacement of the actuator l2 by the electromagnet 52 to move this corresponding bar ll upwardly. The upward displacement of the bar ll opens the switch I! so that the motor 28 cannot initiate its operation while the pin II is up. Upward displacement of the pin ll closes the switch 18 so that the motor In goes into operation closing the switch I8 and carrying the abutment 58 into engagement with the displaced bar II to move the corresponding record on to the turntable andeffect its playing. After the selection is determined by engagement of the abutment 58 with the actuated bar H, the member 8| returns said bar II to its initial position and the phonograph motor l operates to reproduce the recording. Before this recording is completed the return of the pin ll allows the switch I! to closeand the motor 28 is now rendered'operative to dispense the next token 28 to control the actuation of the stepping mechanism l9 to displace the pin ll corresponding tothe next selected recording. This pin ll remains in actuated position until the first recording is completely reproduced and the phonograph has gone through its record changing cycle and returned the second actuated pin ll. whereupon the third token from the bottom is dispensed. This operation is repeated until all the tokens 20 are dispensed. During the dispensing of the last token the switch 38 opens but the switch 31 being closed the motor 28 continues in operation until its full reciprocation is completed. Thereafter the motor. 3| is rendered inoperative until another stack of tokens 28 is placed in the magazine 2|.
