P. Seeburg Corporation, Chicago, 111., a corporation of 11- linois Application October 11, 1943, Serial No. 505,776 21 Claims. (Cl. 177-353) This invention relates to selectors for automatic phonographs in which one or more recordings can be selected for playing seriatim.

One of the objects of the invention is to provide an improved selector which is adapted to control the selection of any of a large number of recordings.

A further object of the invention is to provide an improved phonograph selector arranged to be operated by a plurality of series of impulses, the numbers of the impulses in the two series determining the individual recording selected.

Our improved selector is particularly adapted for use with a dial arranged to transmit a desired number of impulses. This dial may be of conventional type and it may be located at any desired position remote from the phonograph.

While the specific embodiment of the invention hereinafter described is arranged for selecting any of one hundred recordings, this is a matter of convenience only, because the number of impulses-which the dial may be arranged to transmit can be varied at will. Thus, instead of employing a dial capable of transmitting ten different series of impulses, we may arrange a dial to transmit twenty-six or any other desired number of impulses, depending upon the number of selections which the phonograph is arranged to p ay.

It is to be noted that the invention is not intended to be limited to a dial. Any other selector control which can be operated to transmit two series of impulses can be used with the present selector.

In selectors operating with two series of impulses, it has not heretofore beenpossible to use these impulses to transfer a selector member to an individual position by movements in the same direction. Thus, if the selector is actuated to select recording No. 65, then in previous phonograph selectors of this general type a selector arm is located in the sixth row and at the fifth element of that row as a result of the first series of six impulses and the second series of five impulses.

One of the objects of the present invention is to provide an improved selector in which both series of impulses move the same element step by step in one direction. I

In the specific embodiment hereinafter described, I provide means for moving a single selector means first in large steps and then in small steps to correspond to tens and units. For this purpose we employe two separate mechanisms for stepping the tens and units.

to provide a new relation of the steppingmechanisms whereby the mechanisms may be returned in convenient manner to zero positions.

Other objects and capabilities of the invention will appear from the following description of preferred embodiments and the accompanying drawings in which:

Figure 1 is an elevational view, partly in section, through a selector embodying my invention;

Fig. 2 is a sectional plane/thereof, the section being taken on the line 2+2 of Fig. 1;

Fig. 3 is a diagrammatic perspective view of details involving the unit stepper;

Fig. 4 is a plan view of the tens stepper mechanism, this being a sectional view taken on the line 4-4 of Fig. 1;

Fig. 5 is a wiring diagram.

Referring to the drawings, and particularly Figs. 1 to 5 thereof, our improved. selector comprises an arcuate series of selector elements 20 slidably mounted ina stationary frame Al. Each selector element 20 corresponds to an individual recording and the upward displacement of V a selector element 20 starts the motor 22 of the phonograph, with the result that the recordchanging mechanism is put into operation and that individual record is played.

The record-selecting mechanism efiects the return of the displaced selector element 20 after a motor switch, in parallel with the switch elements associated with the selector elements 20, has been closed by the record-changing mechanism.

In copending application Serial No. 342,419, filed June 26, 1940, by Marion R. Winkler, there is shown a plurality of displaceable selector elements which operate and are controlled in the manner just described. In that application the selector elements were actuated from normal position by individual solenoids. In the present application a single element'mechanically displaces the desired selector element 20.

Thus, the phonograph motor 22 may be energized from a secondary 23 of a transformer, one

side of which is grounded and the other is connected to the motor 22. The other side of the motor 22 is connected to an insulated ring 24. Each selector element 20 carries a resilient switch arm 25 which is adapted to engage the ring 24 One of the objects of the present invention is when the selector element is moved upwardly into selecting position. It will be apparent from Fig. lthat when one or more selector elements 20 are thus moved upwardly, the circuit of the motor :12 is completed and the motor goes into operaon. I

A' switch 26 is arranged in parallel relation to the switch elements 24 and 26, the switch 26 being arranged to be momentarily opened at the.

nism of the phonograph so that the corresponding record is moved out for playing. After the drive of the disk 21 terminates. a returning member 26 is moved downwardly so as to return the arresting selector element. The motor 22 continues to operate since the switch 26 is closed until the record is played and the switch 26 is opened by the record-changing mechanism.

In .the mechanism illustrated, the disk 21 moves only in one direction, but our invention is not intended to be limited in this respect. Thus, the disk 21 may be arranged for oscillatory movements and it may be connected for example to the reciprocating carriage shown in application Serial No. 416,140, filed October 23, 1941, by Marion R. Winkler. The present invention is concerned primarily with means for displacing the selecting elements 20.

It will be understood that any desired number of the selector elements 26 may be projected upwardly, in which case the phonograph goes into operation to play the record corresponding to the first selector element 26 engaged by the abutment 26. After thisrecord has been played, the disk 21 resumes its movement and engages the next projected selector element 26 and so forth until all the corresponding records have been played and all the ,projected selector elements have been returned to initial position.

Means are provided for sesiliently holding the selector elements 26 in their normal and projected positions. Thus the frame 2| may include two spaced plates 26 through which the selector elements 26 extend. An annular coil teeth on the ratchet wheel 22. The ratchet wheel 22 is mounted for free rotation on a shaft 24 which is rotatably mounted in a frame 26 below the frame 2| and in axial alignment with the arcuate series of selector elements 26.

A selector arm 26 is pivotally mounted on the upper side-of the ratchet wheel 22. The arm 26 is pivotally mounted on a frame 21 which is secured to the upper side of the ratchet wheel 22 so that the arm 26 extends inagenerally radial or dimetrical relation to the ratchet wheel. The frame 21 may comprise a slotted guide member llaoastoretaintheselectorarmllinradialor diametric relation to the wheel 22 while permitting the arm pivot.

26 to swing upwardly about its.

In alignment with the shaft 24 the arm 36 is provided with an upwardly directed clevis member 26 which has a swivel connection to the armature 46 of a relay 4|. The relay 4| is rigidly mounted on the frame 2| and since the clevis member 29 is arranged in alignment with the shaft 24, it will readily be understood that the.

ratchet wheel 22, together with the arm 36, may rotate freely with reference to the solenoid 4|.

In each of its selecting positions the arm 26 is located beneath one of the selector elements 26 and consequently when the relay 4| is energized, the arm 26 moves upwardly and projects the aligned selector element 26 upwardly with the result that the honograph is set in operation in the manner previously described.

Above the ratchet wheel 32 a collar 46! is rigidly secured to the shaft 34. The collar 4 carries a pin 4 which abuts against a pin 42 carried by the rachet wheel 22. A grooved collar 42 is also rigidly mounted on the shaft 24. A coil spring 44 secured to the collar 42 and to the ratchet wheel 22 tends to keep the pin 42 in engagement with the pin 4| i while permitting the ratchet wheel 22-to be moved in the clockwise direction, as viewed in Fig. 2, to carry the pin 42 away from the pin 4| I.

An escapement wheel 46 is rigidly secured to the lower end of the shaft 24. A long coil spring 46, anchored to the grooved collar 43, extends around a roller 41 mounted on the frame 26 a d extends downwardly to a' suitable point of anchorage, which is shown on the motor 46 carried at the lower end of the frame 36. This spring is arranged so as to bias the shaft 24 in the clockwise direction as viewed in Fig. 2.

As will hereinafter be described, the motor 46 is arranged to drive the shaft 24 to an initial or normal position in which an abutment 49 on the escapement wheel 46 engages an abutment 62 on .the frame 26.

The escapement wheel 46 cooperates with an escapement 6| which is integral with the armsture of a relay 62. The relay 62 is rigidly carried by a vertical shaft 62 mounted on the frame 26 in alignment with the shaft 24'. Also rigidly mounted on the shaft 62 is a contact disk 64 which provides for the connections forthe may 62 and the switch 66 associated with that relay.

The shaft 62 freely carries a gear 66 which is located between two friction plates 61. A sprin 66 abuts against a collar 66 rigidly mounted on the shaft 62 and against apressure disk 66 located on the upper side of the upper friction plate 51. The lower friction plate 61 bears against a plate 6| rigidly mounted on the shaft 52. It will thus be seen that the gear 66 is operatively connected to the shaft 62 by means of an overload clutch which permits slippage of the gear 56 relative to the shaft 62 in the case of overload.

The gear is connected by gear reduction means to the drive pinion 62 of the motor 46. V

gear 62. The gear 66 meshes with a large gear 66 which is rigidly connected to a gear 16 in mesh with the gear 66. The gears 62, 64 and 61, 66 are freely rotatable on a shaftdepending from the frameof the motor 46. The gears 66 and I6 are rigidly secured to another shaft mounted for free rotation on the frame of the motor 46.

The gear assembly 55, 88 is freely rotatable on the last-mentioned shaft.

The gear drive is arranged so that the shaft 53 is positively driven by the motor 48 in the counter-clockwise direction as viewed in Fig. 2.

When the motor 48 is thus put into operation,

the relay 52 is driven in the counterclockwise direction as viewed from above in Fig. 2 and the escapement 5| carries the escapement wheel 45 with it until the abutment 43 engages the abutment 50. As will hereinafter appear, the motor circuit is broken at about this time and any tendency of the motor to overrun is absorbed by the friction mounting of the gear 55.

The teeth on the escapement wheel 45 have a'spacing corresponding to ten spacings of the selector elements or ten tooth spacings on the ratchet wheel 33. It is to be noted that at the beginning of a selection operation, the relay 52 may have any of a plurality of positions with 20 respect to the escapement wheel 45. One position is shown in Fig. 4 but the escapement 5| may be in engagement with any tooth on the escapement wheel 45. In other words, the escapement 5| may have at the beginning of a selection operation its position in Fig. l or any other position one or more tooth spaces from its position in Fig, 4.

The switch 55 mounted on the frame of the relay 52 is arranged to close momentarily each time the relay 52 is energized, that is, each time a tens impulse is received.

The unit-stepping relay I0 is mounted on the frame 35. The armature H of this relay has pivoted thereon an actuating arm or detent I2. The arm 12 is held close to the back of the armature 1| by means of a. strap 13 carried in spaced relation to the" armature H. The arm 12 projects upwardly through an opening 14 in the relay frame to a position close to the teeth of the ratchet-wheel 33.

Each time that the relay I0 is energized the arm or detent. 12 moves into engagement with the ratchet wheel 33 and moves it one tooth space in the clockwise direction as viewed in Fig. 2. The pivotal mounting of the arm 12 on the armature 1| permits the detent to follow the arcuate movement of the ratchet wheel 33 during its engagement. a A holding dog 15, pivotally mounted on the frame of the relay I0, is arranged to engage the teeth of the ratchet wheel 33 so as to hold the ratchet wheel against counterclockwise movement during reception of the units impulses.

I Initially the holding dog 15 is latched out of engagement with the ratchet wheel 33 by means of a locking lever 16. The lever 13 is biassed into latching position by a spring 11. The dog 15 is biassed towards the ratchet wheel 33 by a spring 18. I

The dog 15 is moved into latching position by a lever 13 biassed out of engagement with the dog 15 by a spring 80. An arm 8|, rigidly secured to the collar 43 and consequently to the shaft 34, is arranged to engage the lever IS!v when the shaft 34 is in its normal position with the abutments 49 and 5B in engagement.

The arm 8|, in the initial or normal position of the selector, as shown in Fig. 2, engages an insulation member 82' so as to effect the closing of a switch 83 and the opening of switches 84 and 85. These switches are constituted by levers mounted on the frame of the relay III.

'Switch 83 is biassed open and switches 84 and 85 are biassed closed.

The armature 'll carries an arm 88 which extends from the rear side of the armature and is provided with a bent end which extends behind a pin 81 which projects downwardly from the latch 15. It will thus be seen that when the first units impulse is received, that is, the first impulse which energizes the relay 10, the arm 88 moves the latch 16 into unlatching position so that the dog 15 enters into cooperative engagement with the ratchet wheel 33 during the first units impulse.

Associated with the armature II is a switch 88 which closes momentarily during each units impulse. v 1

In order to facilitate understanding of the invention, a brief description of the operation of the mechanical parts thereof is now given: The first series of impulses are switched so that they energize the relay 52. the relay 52 the escapement 5| is actuated and consequently the shaft- 34 is moved in the clockwise direction as viewed in Fig. 2 a number of tens steps correspondingto the number of impulses received. In the specific embodiment disclosed in Figs. 1 to 5; the arm 35 is located twenty-two steps away from the first of the series of selector elements 20 regarded in the clockwise direction in Fig. 2. Incidentally, for this embodiment the dialling of the number 0 provides two impulses, the dialling of the number 1 provides three impulses, and so forth.

Supposing the number 3" is. dialled first, then v the relay 52 receives five impulses and the arm 35 is brought to a position below the twentyninth of the series of selector elements 2|] regarded in the clockwise direction on Fig. 2. This displacement of the arm 36 results from the displacement ofthe shaft 34 under the influence of the spring 48, the escapement 5| being energized five times. The elements 19, 15 and 16 were initially in their positions shown in Fig. 2. 0n the first impulse the arm- 8| moved away from the lever 19 and from the insulating member 82. Consequently, the switches .83, and 35 moved to the reverse positions from that shown in Fig. 2 on the first impulse. The holding dog 15 remains latched out by its engagement with the latch member 15.

The second series of impulses is arranged to energize the relay 10, once for each impulse. The first units impulse moves the latch 15 to unlatching position so that the dog 15 engages the teeth to the rachet wheel 33. Each energization of the relay 10, moves the rachet wheel 33 one tooth in the clockwise direction as viewed in Fig. 2. During the reception of the units impulses the shaft 34 remains stationary and the rachet wheel 33 is moved against the tension of the spring 44 carrying the pin 42 away from pin 4| l. 7

If the second impulse is caused by moving the dial to the 5 position, seven impulses are transmitted and the arm 36 is moved from the twentyninth to the thirty-sixth selector element 20.

Since the first selector element corresponds to .to No. 35) upwardly. Thereafter the motor 48 is put into operation and it moves the shaft 34 back to initial position with the stops 49 and 50 in engagement.

On each energization of At the time this engagement occurs. the arm i engages the piece of insulation 02 and opens the switch 00, whereupon the motor ceases to be energized. At the same time, the arm 0| swings the lever into engagement with the dog 10 so that this dog is operatively disengaged from the rachet wheel 00 and is latched out automatically by the latch 10. The disengagement oi the dog from the rachet wheel 00 enables the spring 00 to turn the rachet wheel I; back to initial position which is defined bythe engagement of the pin 02 with the pin H I.

It is to be noted that when the motor 40 thus operates, it carries the escapement I in the counter-clockwise direction five steps from its original position shown in Fig. 4. During successive selections the rachet ii is moved in counterclockwise direction a certain number of tens steps corresponding to the number of the tens impulses in the selection last made.

Referring now to Fig. 5, the manually operable dial 00 cooperates with the switch 00 so that on the manual action of the dial the switch 00 remains open and when the dial is released to resume normal position, the switch 90 is closed a number oi times, depending upon the displacement of the dial. One side oi the dial 00 is grounded, the other being connected-through a limiting. resistor (suitably 10,000 ohms) to the grid of a gas tube II. This tube may suitably be a 205i tube, the grid of which is connected I is connected to one side of the relay 5!. The

other sides oi the relays 02 and 10 are connected to the high side of the secondary ll of the power transformer 00. The other side of the secondary.

84 is grounded. The high side of the transformer 00 is connected to the plate of the tube Si by a by-pass condenser 00. switch 00 is connected to the common pole of the two switches 0H and 02. One side 01 the switch [I is grounded, the other being connected to one side 01' the relay 00. The other side or the relay is connected to a source of 200 volts D. C. This source is also connected to one side oi the relay 91 and through a limiting resistor 00 (suitably 100 ohms) to one side of a normally open switch 00 controlled by the relay 01. associated with the relay 91 is a normally closed switch I00. The common pole of the two switches 00 and-i00is connected through a condenser III to ground. The other side of the switch I00 is connected to a relay I02 which controls the normally open switches I03 and I04.

Two sides of the switches I00 and I04 are connected together to the high side of the secondary I00 oi the transformer 05 and to normally open switches I06 and I01 controlled by relay I00. The other side of the switch I01 is connected to the motor 40, the other side of this motor being grounded. The other side oi the switch I00 is connected to the other side of the relay I00 and to the other side of the switch I04.

The other side of the.

Also

to the relay 0i, the other side of which is grounded. Relays 03 and 01 are slow-release relays so that they may remain energized dur-- ing th reception of decades impulses and units impulses, respectively.

The operation will now be amplified with reference to Fig. 5 and with reference to the previous description of the mechanical parts of the selector. Actuation oi the dial 00 results in the closing of the switch 00 five times. Each time the switch is closed, the voltage of the grid of the tube 8i becomes substantially zero and the tube flashes. The first flash of the tube supplies plate current from secondary 8|, relay 10, and normally closed switch 00. After the first impulse switch 83 is opened and switches 04 and are closed, the first energization oi the relay 10 closes the switch 00 and completes the circuit of the relay 00 so that switch 02 closes and switch 9 opens. Relay 93, being a slow-opening relay, maintains these switches in the conditions mentioned during the reception of the tens impulses. The second'and subsequent tens impulses pass plate current from secondary 00 through relay 10, closed switch 82 and closed switch 84. The relay 10 thus receives five impulses and the arm 30 is moved to a position beneath the twenty- -ninth selector element 20 (No. 28). On the termination of the tens impulses the relay 0! becomes deenergizecl, the switch 02 opens and the switch I closes, switch 03 remains open and switches 04 and 80 remain closed.

For the second or units impulses. the dial is operated with the aid of the opening corresponding to 5," and consequently the switch is closed seven times. The plate circuit is completed through closed switch 80, closed switch I, relay I2 and secondary 04. On the first units impulse, the relay 01 closes switch 00 and open switch I00. This condition persists during the reception of the units impulses and the condenser MI is charged at 200 volts D. C. Each unit impulse energizing the relay 10 moves the ratchet wheel one tooth in the clockwise direction as viewed in Fig. 2, that is, a total of seven teeth, so that the arm 30 is brought beneath the twenty-sixth selector element 20 (No. 35). At the end of the second series of impulses, relay 01 becomes deenergized, switch 00 opens, and switch I00 closes. The condenser IOI then discharges throughthe relay I02, energizing this relay and closing switches I00, I00. The closing oi the switch I00 completes a circuit from secondary I00 through relay II so that the arm 00 is moved upwardly to project selector element 20 (No. 35) upward to selecting position.

The momentary closing oi the switch i00 energizes relay I00 through the closed switch 00. The energization oi the relay I00closes switches I00 and I01. The closing of the switch I01 completes the circuit of the motor 40 so that the same starts to operate to return the shaft 00 towards.

its initial, position wherethe abutmcnts ll and I0 engage. The closing of the switch I00 maintains the relay I00 energized through the circuit I00, I00, I00 and closed switch 80.

When the motor 00 has driven the shaft 00 almost back of its normal position, the arm II misses the piece oi insulation 02 and opens the switch 00. At the same time the arm 0i turns the lever 10 in clockwise direction as viewed in Fig. 2, moving the dog 10 clear oi the ratchet The other side or the switch III is connected 75 wheel 00. This ratchet wheel is now rotated in counterciockwisedirection as viewed in Fig.2

by" the spring 44 until the pin 42 hits against the pin ll l.

The movement of the dog 15 by the pivoted lever I9 results in the automatic latching out of the dog 15 as shown in Fig. 2 and the dog 15 remains in this latched-out position until the first units .energization of the next selection operation again energizes the relay 10.

It will be understood that any desired selector elements 20 and any desired plurality thereof can be projected upwardly by a sequence of double actuations of the dial 89.

It may here be remarked that if the No. is dialled twice, the arm 36 is advanced twentytwo steps, so that the first of the selector elements 20 (No. 00) is projected upwardly. It is preferred to have at least two impulses to prevent the selector from responding to accidental impulses onthe line. Accidental impulses will ordinarily not have the time relation necessary for maintaining the relay 93 or relay 91 energized.

No selection can be made by two accidental impulses. It requires two pairs of at least two impulses with the proper time relation to effect actuation of any selector element 20. It will of course be understood that we may use a greater number of fdead impulses. Thus we may arrange the mechanism so that the dialling of 00 gives two series of three, four or more impulses to bring the arm 36 into alignment with the first selector element 20 (No. 00)

It will of course be understood that the dial 89 may be located at any suitable position remote from the restof the mechanism herein described. The line connecting the switch 90 to the limiting resistor may be of any desired length and this line is consequently shown broken in the drawings.

Although the invention has been described in connection with specific details of a preferred embodiment thereof, it must be understood that such details are not intended to be limitative of the invention except in so far as set forth in the accompanying claims.
