Thpinx43:remains-1imthiapositionfuntit `It will be understood that when one or more of the fingers 42 is in contact with corresponding fingers 40, the circuit through the relay 3|] is complete, and the switches 3| and 32 are closed so that the motor I6 remains in operation until all the pins 43 are in normal position, that is, the full line position shown in Fig. 2, and the switch I is thereafter opened by the arm I4, which occurs immediately after the playing of each record. The armature 45 is biased forwardly, or to the left, as viewed in Fig. 2, by a spring 41, which bears against the solenoid '24 and against a head 48 on the forward end of the armature 45. A stop 49 is provided against which the head 48 abuts in normal position of the armature 45.

In order to prevent displacement of the selector elements unless the displacing means is properly positioned relative to the elements, whereby actuation of elements may be made more readily and rapidly even when closely spaced to enable a large number of records to be selected, and when the displacing means may be moved rapidly by power means, there are provided means for preventing energization of solenoid 24 unless such proper positioning exists. The disc 34 is provided with a circumferential series of notches corresponding in number to the number of records; that is, in the case of the embodiment of the invention shown in Fig. 1, there are twenty notches. A spring pressed arm 66' carries a roller 61', which is adapted to remain in one of the notches on the disc 34, except when it is being turned by the handle I8. The solenoid 24 is located on the disc 34 so that the pin 44 is in alignment with one of the pins 43 in each position of the roller 61' within one of the notches in the disc 34. The arm 66 carries a projecting pin 68 which is adapted to hold the switch 23 open, except when the roller 61 is located in one of the notches of the disc 34. It will be understood that when a coin is inserted in the coin chute I1, a circuit is completed from ground, contact I9, contact 20, switch 23 which is closed only by the proper positioning of the roller 61 in one of the notches of the disc 34, solenoid 24, conductor 25, and secondary of the transformer 26, back to ground. Thus, the solenoid 24 is energized and the aligned pin 43 is moved rearwardly into the dotted line position in Fig. 2. 1

The shaft Ill carries a notched wheel 50 of insulating material, this wheel being provided with notches corresponding in number to the number of selections in the phonograph. This notched wheel cooperates with a pivoted arm 5I, which is biased towards it by ra-spring 52. The arm 5I carries a contact 53 which is adapted to engage a stationary Contact 54 each time that the nose 55 of the arm 5I moves into a notch in the wheel 50. The contact 54 is connected by a conductor 56 to one side of a solenoid 51 in the control unit. The other side of the solenoid 51 is grounded. The armature 58 of the solenoid 51 is connected to an escapement member 59 which is pivoted at 60. The escapement member 59 is biased towards its normal position shown in Fig. 1 by means of a spring 6I. The escapement member 59 is provided with detents 6I-and 62 which cooperate with a ratchet wheel 63 rigidly mounted on a shaft 64. This shaft 64 is mounted in axial alignment to the spindle 36 and carries at its end adjacent thev disc 31 an arm 65 of insulating material. When the solenoid 51 is energized, the detent 6I engages'one of the teeth of thel ratchet wheel 63 and moves-it one increment of a tooth space in the clockwise direction. When the solenoid 51 is de-energized, the spring 6I carries the detent 62 into engagement with one of the teeth of the ratchet wheel 63 and moves it the remainder of the tooth space. Thus, the ratchet wheel 63 is moved one tooth space in two separate increments, the shaft 64 being stationary for a definite short period between the two increments.

In order to effect the selection of a record when the movable member 65 is in cooperative relation to an actuated pin, means are provided for closing a control circuit when a pin is engaged. Preferably, but not necessarily, the arm 65 is provided with a circuit controlling dog 1I adapted upon engaging a pin to close a circuit between contacts 66 and 14. The arm 65 carries the contact 66 which is connected to a slip ring 61 mounted on the arm 65. The slip ring 61 is engaged by a brush 68, which is connected by a conductor 69 to an electromagnet 10. The other side of the electromagnet 10 is connected Vto the ungrounded side of the secondary of the transformer 26. A dog 1I is pivotally mounted on the arm 65. This dog is connected to the shaft 64 (which is grounded) and is normally biased by a spring 12 against a stop 13. The dog 1I is adapted to engage any of the pins 43 which have been displaced inwardly. When the dog 1I engages such an actuated pin 43, it is swung so as to bring the previously referred to contact 14 into engagement with the contact 66. The arm 65 is mounted on the shaft 64 sothat this contact is made when the ratchet wheel 63 receives its first increment of movement from the detent 6I. Consequently, the engagement between the contact 14 and 66 persists for the short, definite period previously mentioned. When this enr gagement is effective, the electromagnet 1D is energized and its armature is withdrawn from the latch II sothat this latch is released to engage a latch wheel 15 which is carried by the shaft I0. The detent 16 of the latch II consequently enters a notch in the latch wheel 15, thus holding the shaft I0 against further rotation. A member 11 on the phonograph engages the latch II at an intermediate point of the record changing cycle and re-engagesA the latch II with the armature of the magnet 10.

The shaft 64 carries a vdisc 18 whereby the shaft may be brought into synchronized relation with the shaft I0. Thus, as shown in Fig. l, an arrow 19 on a stationary portion of the device indicates the position of the arm 65 with respect to the number of the recording shown on the disc 16. The latch II is adapted to engage the notch in the latch wheel 15 corresponding to record No. 6, and the arm 65 should be in the No. 6 position, as shown in Fig. l. If it is not in this position, it may be rotated thereinto by manual actuation in the counterclockwise direction. The disc 18 is, of course, normally enclosed by the housing of the control unit. A pointer 86 on the handle I8 indicates on the circular indicia strip 8 I (Fig. 5) the recording for which the solenoid 24 is adjusted. Stop means 84 are provided on the disc 34 and on the stationary part of the device: so that simple conductors may be connected to the solenoid 24 without danger of fracture.

The operation is as follows:

The handle I8 is rotated until its pointer 80 is in registry with the number of the recording which it is desired to select. The disc 34 is held in this position by the roller 61', and the switch :Maese 23lisf. closed,i but only, when the armature is prop-fi erly positionedr to move-la pinl A coin of ape' propriete' denomination is inserted in the; ooirr chute I1, and aV circuit is completed through: the solenoid` 241.50 lthat its armature 4'5 pushes the cor-'r responding pin 43 into selecting position, wh-i'eh7 is the-ldotted-'line positionLirlrFig.- 2v.- 'I-lf'ie engage--V ment of the arnrfizr with the arm 40oorr1plete'sltl'ie circuit through the relay' 3IF- and-1 the- Switches 3.15 and 32 arerclosed.

energization of either of these magnets initiates operation of the motor 48 and results in the removal of a record from the magazine to the turntable, or vice versa. When that particular operation is completed, the record changing mechanism returns the armature 248 and the bar 200 to neutral position, thus terminating the record changing operation.

The record magazine 29 moves to the left and to the right, being actuated by a pinion 68 which cooperates with an endless rack 11 on the magazine 29. When the magazine 29 stops, one of the records is located in alignment with the record transfer member |34', this member removing the record from the magazine and placingrit with a pre-determined side up, the particular side being turned up for reproduction depending on the direction in which the magazinel 29' is eprogressing.

Upon the magazine 29 I mount a notchedbar 260 which is adapted to cooperate with a switch 210. It will readily be understood that when the magazine 29' moves one record space with respect to the record transfer member |34', the switch 210 is closed. One side of the switch is connected to the ungrounded side of the secondary of the transformer 259. The otherside is connected to the solenoid 51 which moves the arm 65 step by step in the manner described in connection with Figs. 1 and 2. It will, of course, be understood that this step by step movement may be effected bymeans of a motor, for eX- ample, the motor 81, described in connection with the modification shown in Figs. 5, 6 and '7. When the dog 1| mounted on the arm 65 engages an actuated pin 43, contact 14 engages contact 66 and a circuit is completed through these contacts, ring 61, and brush 68 to the electromagnet 254, thus displacing the bar 200 to the left.

The pins 43 are actuated by means of the solenoid 24, which is connected to the ungrounded side of the secondaryy of the transformer 259 through a switch |30, which may be a coin actuated switch cr may be actuated manually.

The operation is as follows:

The switch I 9| is closed either manually or by means of coin control mechanism. The motor 35 is thus put into operation and the turntable is rotated continuously until the switch |I is again opened. It will be understood that this opening may be effected in known manner by the mechanism shown for this purpose in the Green patent referred to, or in any other suitable known Way.

The switch 204 being in its normal closed position, as shown in'Fig. 4, the motor 48 also starts to operate, the result being that the-'pinion 68' moves the magazine 29' to the left and to the right. During this movement of themagazine, the switch 210 is closed periodically, and the arm 65 is rotated step by step as long as the movement of the magazine 29 continues. I'he operator locates the "solenoid in alignment with the selection whichhe desires to have played and then he closes the switch |30, energizing the solenoid 24 and moving the selected pin 43 inwardly. He may actuate as many pins 43 as he desires. v

The arm 65, moving step by step around the pins 43 in the manner previously described, moves the dog 1| into engagement with an actuated pin and it is swung so as to complete the circuit through the electromagnet 254. The bar 200 is thus moved to the left. This movement has '10 no effect on the switch 204',v but it does have the effect of releasing a clutch which controlsth'e movement of the magazine 29'. The displacement of the bar 200 to the left starts the operation of the record transfer -member |34 so that the record in alignment therewith whenv the magazine 29 stops vis removed and placed upon the turntable. When this record transfer movement is completed, the record transfer mechanism returns the bar 200' to its neutral or intermediate position. This movement of the bar 200 to the right causes the projection 2|0..to swing the switch 204' in the clockwise direction, as viewed in Fig. 4, thus terminating the operation of the motor 48 during the reproduction of a record. When the record is completed,l a switch controlled by the tone arm completes the circuit of the electromagnet 241 so that the bar 200- Iis moved to the right. This movement brings the projection 2|0 past the projection 21|' and the spring 206 throws the switch 204' to closed position, thus starting the motor 48. The displacement of the bar 200' to the right also engages-a clutch which puts the recordtransfer member |34 into operation to pick the record-01T the turntable and return it to its .place in the magazine. When this operation vis effected, the record changing mechanism. returns the bar 200' to its neutral or intermediate position, thus disengaging the aforesaid clutch. During the lastpart of this movement, the clutch which connects the motor 48' to the-pinion 68 is reengaged. If the switch |9| is maintained closed, the magazine will vresume its movement until the dog 1|v again encounters an' actuated button,- whereupon the magnet 254 will be energized and the cycle thus far described will be repeated. f

It is to be noted that there arel -twoseries of pins 43,- one series corresponding vto the left hand side of the records in the magazine, and the other series corresponding tothe right hand side of the records in the magazine. These series are separated by blank positions or spaces in which the arm moves when the contact member of the switch 210 `moves past the extreme projections on the bars 260. Consequently, the ratchet wheel 63 should havea number of teeth correspondingto double the number o1' records, plus two, for this type of reciprocating magazine. Y

In the embodiment of the invention shown in Figs. 5, 6 and. v7, theconstruction is generally similar to thatof lthe device shown in Figs 1 and 2, and similar reference numerals are applied to corresponding parts. In-this embodiment of the invention, the pinsl43- extend free- Ily-fi'hrough'openings in the -plate 31; Mounted upon-this plate', on the rear side thereof, is a stationary disc 85, with which the frustro-conical portion 46 of a pin is adapted to cooperate in the manner shown on the right hand side of Fig. 5, i. e., the plate latches the pin in actuated position.

This embodiment of the invention is arranged for'the control of forty recordings, and conse- 13 o1.' the disc 15 in selecting position, the relay 30 remains energized through switches 3| and I5. At the end of the playing of the last recording, the finger I4 opens the switch I5 and the machine stops.

In Figs. 9 and 9A there is illustrated a further embodiment of a selector element operating means provided with means for preventing operation thereof to actuate an element unless the operating means is properly located to the element. In this embodiment the operating member is movable manually both to select and to operate elements, but it should be understood that it could be operated otherwise .and from remote points, if desired.

The selector pins 43 are cooperatively associated with a latching plate 31 secured as to a stationary bushing supporting also the contact iingers 40 and 42, and a plate I3I provided for a purpose to be set forth in detail shortly. 'Ihe contacts 40 and 42 are insulated from eachother, and contacts 40 and 42 are likewise insulated from the supporting structure, as heretofore s et forth.

The pin selecting and operating means, indicated generally by reference character |32 includes a rotatable and axially movable shaft |33 supported by bushing |30. This shaft is biased to an outer normal position by spring |34 bearum When the knob is pushed in the selected pin 43 is moved by the reduced end I3'I of a stud |38 secured to the outer end of a radially extending arm |39 secured to the collar |35 so that it rotates and moves axially with shaft |33.

In order to prevent operation of mechanism to move a pin unless the stud is properly aligned with a pin 43, the plate |3I, located between the stud and pins, is provided with a series of apertures |40 of a diameter slightly larger than the reduced end |31 of stud |38. Consequently, the knob cannot be pushed in unless the stud is correctly aligned relative to the pin. As heretofore indicated, this construction enables pins to be placed close to each other and get operated easily and quickly and without damage as a result of jamming or the like.

The making of selections is further facilitated by providing the apertures with countersunk portions I40A adapted to receive the adjacent end of a positioning element |4| slidably carried by the stud |318 and biased toward the plate I 3| by a spring I4IA located in its interior. This construction makes the apparatus substantially selfcentering.

In the embodiment shown in Figs. 1 and 8, I may dispense with the holding circuit provided by switches I and 3| and maintain'the motor switch 32 closed by mechanical means. Thus, as shown in Fig. 10, the armature of the electromagnet 30 is carried by a pivoted latch member |42 which is biased away from the magnet by a spring |43. It may be well to note again that the elements shown in Fig. l0 may be substituted for those portions of Figs. l and 8 enclosed in the dash lines.

The contacts constituting the switch 32 are carried by two pivotally mounted arms |44 and |45. These arms are biased toward make position by a spring |46. The arm |45 is biased by a stronger spring |41 toward a cam |48. The

cam |48 is mounted on the cam shaft I2. The arm |44 is adapted to cooperate with the latch |42.

When the magnet 30 is energized by engagement between the arms 40 and 42 of the embodiment of Fig. 1 or by closing of the switch I I4 in the embodiment of Fig. 8, the latch |42 is moved away from the arm |44 so that the switch 32 is yclosed and the motor is placed in operation.

If a plurality of pins 43 are actuated, then the magnet 30 remains energized during all the corresponding plays except the last play. During the record changing cycle between successive plays, the arms |44 and |45 are oscillated without, however, separating the contacts constituting the switch 32. When the shaft I2 is at rest during the playing of a record, the arm |45 rests against the highest point of the cam |48 and the arm 44 is beyond the detent of the latch |42.

During the last record changing cycle, that is, the cycle which brings out the last record for playing, the shaft I2 rotates in a clockwise direction so that the yarm |45 moves off the high point of the cam |48 and the arm |44 follows it, since the magnet 30 is still energized. When the lastv pin 43 is discharged, the magnet 30 is deenergized and the latch |42 moves downwardly under the influence of the spring I 43.

At the completion of the record changing cycle, the highest point of the cam |48 is in engagement with the arm |45 and the arm |44 is moved thereby past the detent of the latch |42. During the playing of the last record, the arm |45 is engaged by the highest point of the cam |48. At the end of the playing of the last record, the shaft I2 starts to rotate and the arm |45 drops off the highest point of the cam |48 into contact 'with the lowest point of this cam while arm |44 is restrained by the latch, thus separating the contacts constituting the switch 32 as shown in Fig. 10.

In the embodiment shown in Fig. l1, which like the apparatus shown in Fig. 10 may be substituted for those portions of Figs. l and 8 blocked olf in the dash lines, a collar |49 is mounted on the shaft I2. This collar is provided with a peripheral recess |50 which is adapted to receive a projection I 5| on a pivotally mounted arm |52. This arm is biased by a spring |53 which tends to bring the projection |52 into the recess |50. 'Ihe arm |52 carries the armature of the magnet 30 which is adapted to raise the arm and to bring the projection I5I out of the recess |50.

The switch 32 is constituted by a contact on the arm |52 and a contact on a resilient arm |54. When the magnet 30 is energized, the switch 32 is maintained closed, and consequently, a plurality of records may be played without lmovement of the arm |52.

During the record changing cycle for the playing of the last selected record, the pin 43 being returned to normal position, the electromagnet 30 is deenergized. At this time, the projection |5| engages the periphery of the collar |49 and the switch 32 is maintained closed until after the last record is played.

When the last record is played, the record changing cycle again comes into operation and the cam shaft I2 starts to rotate. Immediately after this rotation begins, the recess |50 is brought into alignment with the projection |5| and the arm |52 is moved away from the magnet 30, thus opening the motor switch 32.

It will be understood that the operation is in -all respects similar to that described above in atrasos connection with Figs. 1 and 18, with Athe exception that the holding circuit, including switches 3| and l5, is dispensed with, the switch `32 being Y.held closed mechanically after the electromagnet 3B is deenergized and until the last record is played, whereupon the motor IG stops.
