w 557 PIIVIQ Patented Dec. 18, 1945 OFFICE AUTOIVIATIO PHONOGRAPH Mahlon W. Kenney, Oak Park, Ill., assignor to J. P. Seeburg Corporation, Chicago, 111., a corporation of Illinois Application November 4, 1944, Serial No. 561,987

18 Claims. (Cl. 177- -353) This invention relates to automatic phonographs and particularly to multiselective automatic phonegraphs having a plurality of recordings available for selections by the operator.

One of the objects of the present invention is to provide an improved multiselective phonograph in which the operator can select a plurality of recordings to be reproduced in the order in which the selection is made.

In copending application Ser. No. 524,232, filed February 28, 1944, by Mahlon W. Kenney and Hugh H. Davis, there is described and claimed a chronologically selective phonograph having an elongated member such as a tape upon which a plurality of selections are stored in the form of perforations made in the longitudinal direction of the tape. The number of perforations is individual to each selection. In the machine of the application referred to each selection consisted of two separate trains of perforation. In the normal, operation of that machine a plurality of selecting signals were applied to the tape and the phonograph was put into operation to take the signals from the tape and to play the corresponding recordings in their order on the tape. After the reproduction of each recording,

another signal was taken from the tape and so forth until all selections were taken from the tape and the corresponding recordings reproduced. The matter of storing the portion of the tape carrying a large number of signals presents considerable difllculty when a large program is preselected.

The principal object of the present invention is to provide a phonograph in which the signals are recorded upon a broad tape in the transverse direction of the tape so that a large number of selecting signals may be accommodated in a relatively short length of tape, obviating the diiilculties presented by the narrow tape in which the signals are applied in the longitudinal direction of the tape.

Other objects, advantages, and capabilities of the invention will appear from the following descrlption of a preferred embodiment thereof taken in conjunction with the accompanying drawings, in which Fig. 1 is a diagrammatic view and wiring diagram of the phonograph;

Fig. 2 is a perspective view of the signal printing or punching mechanism and the paper stepping mechanism;

Fig. 3 is a perspective viewof the signal pickup mechanism and the tape takeup roll; and

Fig.4 is a fragmentary elevation, partly in section of the feed screw of the pickup mechanism. In the embodiment of the invention described and illustrated the selecting signals are created ated to select recordings from 00 to 99. If the No. 0 is dialed three impulses are created, if the No. 1 is dialed 4 impulses are created and if No. 9 is dialed 12 impulses are created. When the dial is thus actuated the printing or punching mechanism ll applies 3, 4 or 12 space perforations in the transverse direction upon a broad tape l2. After each punching operation the tape I2 is fed to the right as viewed in Fig. 1 a short distance by the paper feed mechanism l3 so that the various trains of perforations are spaced in the 1ongitudinal direction of the tape. The tape I 2 may be paper tape of the type used in adding machines and may be approximately two or three inches wide, the machine being preferabl adapted to take a standard tape which can be purchased in rolls. After two trains of perforations, corresponding to an individual recording, have been applied to the tape the motor It goes into operation to feed the tape to the right as viewed in Fig. 1 until the first train of impulses is brought into cooperative relation with the signal pickup mechanism I5. The tape [2 then stops and the mechanism [-5 picks up the first train of impulses and supplies the same to the stepping mechanism IS. The stepping mechanism l6 and the associated elements may be substantially similar to those described in copending application Ser. No. 505,776, filed October 11, 1943, by Mahlon W. Kenney and Herman G. Jensen, or the copending application Ser. No. 561,986 Case 6) filed by the same applicants on November 4, 1944. These elements will therefore be very briefly described herein. The stepping mechanism IS on its first actuation carries an actuator IT a correspondingnumber-of large steps from its initial position. The second operation of the stepping means l6 carries the actuator l1 around a corresponding number of small steps. The actuator I1 is arranged to cooperate with any of one hundred selector bars l8 which are arranged in arcuate or circular path. The bars l8 are equally spaced and the large steps of the stepbrings the actuator the motor 22 puts the selecting mechanism of the phonograph into operation and closes a switch 23 in parailelwith the switch 2| so that the motor 22 remains in operation until the selected recording has been completely reproduced and the switch 23 is again open, notwithstanding that the switch 2| may be opened before the complete reproduction oi the recording, as will hereinaiter be more fully described. -The record changing mechanism drives a disc 24" through at least one revolution so'that a projection 25 thereon enases the bar. l8 which is upwardly displaced.

, This engagement arrests thedisc 24 which is frictionally driven. The arrested position of the disc 24 determines the recording which is reproduced by the phonograph.- After the recording has been determined the electromagnet 28 is automatically energized momentarily so that the plunger 21 adjacent the abutment 25 is moved downwardly to return the arresting bar |8 to its normal position. The relay 20 is deener d but the phonograph motor-22 continuesto operate since the switch 23 is closed. In the event that the operator has made at leasttwo selections the pickup mechanism is goes into operation to displace the bar l8 corresponding to the second selection. -When any bar I8 is displaced the pickup mechanism is rendered inoperative. Thus the normal operation or the phonograph is that L a recording is being reproduced and the bar 18 for the next recording is displaced. The remaining selection signalsare stored in the tape between the punching. mechanism II and the pickup mechanism l5. Normally the portion oi the tape bearing the signals may accommodate itself in-a depending loop as shown in dot and dash lines at'28 in Fig. 1. Since a large number of selections may be recorded on a relatively short piece of tap the accommodation of the loop 28 is very easily provided. Since the tape is quite broad a large loop 28 can be accommodated without any tendency to snarling.

= The supply of tape is in the form of a roll 29 rotatably mounted on a spindle 30. A'brake 3| bears against the roll so as to keep the paper taut. The tape |2 pwses from the roll through guides 32 on the punching mechanism, through feed rolls 33 o! the paper feed mechanism l3 between the contacts 34 and 35 of the pickup mechanism I! to the takeup drum 38 which is driven in clockwise direction as viewed in Fig. l by a motor |4 through suitable gear reduction.

l'dler rolls are provided for guiding the paper at intermediate points.

Power is supplied to the unit by the primary 3'! of a transformer 88. A secondary 39 of the transformer provides filament current to two grid controlled thyratron tubes 80 and GI. A secondary i2 is connected to the plate of the "thyratron" as and to the solenoid d3 which operates the punching mechanism. The other side of this solenoid is grounded as is the cathode of the thyratron til. A secondary 33 supplies A. 0. current to the line 85. A secondary 55 supplies current to the filament cathode of the push pull rectifying tube 41. The anodes oi the tubes 41 V are connected to the ends of the secondary 48, the center tap oi. which is grounded through a limiting resistor 43. The output of the rectifier 41 is filtered by the filter 50 and the direct current is supplied to the line The secondary 52 is connected to the stepping unit It by a line 58 .and to the plate of the .thyratron 4|. The other line st connectedto the stepping unit l6 isl grounded as is the cathode of the thyratron" 4 The dial it operates the impulse switch 55.

this switch is grounded and the other One side of is connected to the control grid of the thyratron 48. This grid is negatively-blessed bya line 55 through suitable limiting resistors. When the dial is operated and released the switch 55 closes a corresponding number of times eiiectually grounding the control grid of the thyratron 40 with the result that a corresponding number of actuating impulses is supplied to the solenoid 43. During the repeated energization of the solenoid 43 the switch 51 is repeatedly closed. One side of this switch is grounded, its other side being connected. to the slow release relay 58 which is also connected to the D. C. line 5 I. Consequently the relay 58 remains energized during the reception of a train of impulses by the sole- One contact of the switch 53 is connected to the D. C. line 5|. When the relay 58 isenergized the movable pole oi the switch 58 engages this contact. This movable pole is connected to a relatively large condenser 8| the other side of which is grounded. Consequently when the relay v 58 is energized the condenser 8| is connected to the D. C. line 5| and is charged. When the relay 58 is de'energized at the end or a train of impulses the movable pole engages the other contact-oi the switch 58 which is connected to the relay 82 so that the condenser is discharged through the relay 82, the other side of which is grounded. It may be'here noted that during creation of. impulses by the dial l8 the switch to is open and the electromagnet 83 is deenergized.

' The discharge of the condenser 8| through the relay 82 closes the switches 54 and 85. One side of each of these switches is connected to the A, C.

line 45. The other side of the switch- 84 isconnected'to the reset magnet 88 of the punching unit II and to the paper feed magnet 81. The other sides of these'magnets are grounded. The

other side of the switch 65 is connected to the electromagnet 58. the other side of which is grounded. The armature of the electromagnet 88 cooperates with a toothed counting wheel Hi. This armature extends through a window "so that its movement is limited to efiectthe displacement of the counting wheel no one tooth in the counterclockwise direction as viewed in Fig. l. A spring pressed detent 12 holds the wheel in in the position into which it is actuated.

In its normal position an abutment 13 on the wheel in engages a stationary abutment 14. An abutment -15 on the wheel in normally holds a switch 18 open. When the wheel lois displaced noid 43. The relay 58 controls the two Way switch 59 and the normally closed switch 80. v

the transversedirection of the tape. The screw I2I is provided with a helical groove I22 which is engaged by a. tooth- I23 slidablymounted on the carriage H8. The tooth I23 isbiassed towards the screw I2I by a spring I24. .An upwardly directed arm I25 integral with the tooth I23 controls the switch 81 which is mounted on the carriage H8. When the tooth I23 is in the groove I22 the switch 81 is closed. The upperend of the arm I25 carries a recess I26. A dog I21 pivotally mounted on the carriage H8 is adapted to enter the recess I28 under the influence of its spring I28 when the tooth I23 is moved radially away from the screw I2 I. When the tooth is thus moved radially away from the screw I2I the switch 81 is opened and it is locked open by the dog I21. The radial movement of the tooth I23 is efiected at the end of the inward traverse of the frame II8 by the cam-shaped portion I29 of the groove I22 best shown in Fig. 4'. At the end of the traverse of the carriage II8 the tooth I23 rises on the camshaped portion I28, the switch 81 is opened and the tooth I23 is located out of the groove I22. The carriage I I8 is biassed towards its initial position by means of a spring I38 so that when the tooth I23 islatched out by the dog I21 the carriage I I8 returns to its initial position. The carrlage II8 carries an electromagnet I3I which is adapted, when energized, to attract the tail of the dog I21. One side of the magnet is connected to the AC line 45. The other side of themagnet is connected to a contact I38 which is adapted to The contacts I36 and I 31 are in alignment with the contacts 34 and 35 in the longitudinal direction of the tape and they are located to the right of the contacts nine times and the relay 58 remains energized.

Consequently when the contacts 34 and 35 are scanning a row of per- While the relay 58 is energized the switch 88.

The switches 84 and 85 close momentarily with the result that the magnets 88, 81 and 88 are momentarily energized. The wheelv 18 is moved one tooth in the counterclockwise direction. mechanism are raised from the ratchet wheel I82 so that the spring I85 returns the carriage 88 to its initial position. The energization of the mag! net 61 moves the tape at the punching mechanism II one step to the right as viewed in Fig. 1. The switch 16 remains open since the wheel 18 has merely moved one tooth in the counterclockwise direction.

When the operator dials the No. 4 the same operation is repeated and seven perforations are madeacross the tape. In this case the second energization of the relay 88 moves the wheel 18 the second tooth in the counterclockwise direction as viewed in Fig. 1 closing the switch 18. When the switch 18 closes the circuit of the motor I4 is completed and the electromagnet 63 is energized. The motor I4 consequently drives the takeup roll 36 but the screw I2! is not driven because the electromagnet 84 is not'energized. The

- circuit of the motor is completed through switch 16, switch 88, motor I4 to A. C. line The circuit of the magnet 83 is completed through switch 18, switch 88, switch 8I, switch 60, electromagnet 83, switch 83 to A. C. line 45. The paper is consequently driven to the right as viewed in Fig. 1 until the first perforation of the first train permits engagement between contacts 34 and 35. This engagement energizes the relay 88 through the closed switch 81 closing the contacts 89 and 88 and energizing the relay SI. This opens the switch IN and closes the switch 86 energizing the magnet 84 and deenergizing the magnet 83. Deenergization of the magnet 83 ar- 5 rests the drive of the roll 38 so that the paper the electromagnet I 3| is energized and the dog I21 unlatches the tooth I23 so that it is biassed towards the screw I2I. When the screw I2I is tape is stationary with the contacts 34 and 35 engaged through the first perforation of the first train. The circuit of the motor I4. is maintained and since the magnet 84 is energized the screw I2I is driven and the carriage H8 i moved in again put into rotation the tooth I23 drops into the groove I22 and the switch 81 is again closed so that the circuit of the contacts 34 and 35 is conditioned for cooperation with the next row of perforations.

The screw I2I is driven from the motor I4 by means of a sprocket chain I32 and a friction clultch I33. The screw I2I rigidly carries a toothed wheel I34 which is normally engaged by a dog I35 to prevent rotation of the screw. The tail of the dog I35 is arranged to be attracted by the electromagnet 84 mounted on the fram I28 so that when this electromagnet is energized and the motor I4 is in operation the screw IN is driven.

The operation will now be described in case that the operator dials two numbers corresponding to a definite recording such as No. 64. The operator dials 8 and when he releases the dial the switch closes nine times. The thyraltron 48 flashes nine times and the solenoid 43 is energized nine times The punch 31 punches nine equally spaced holes in a line across the tape I2. During these nine punching operations the switch 51 closes the transverse direction of the paper so that the relay 88 is energized nine times. The closing of the switch 88 nine times causes the thyratron H to flash nine times and nine stepping impulses 55 are supplied to the stepping mechanism I8 mov- 5 has made its full travel and has returned to its initial positionl When the carriage I I8 has made its full travel across the paper the switch 81 is locked open and during the return movement of the carriage II8 the circuit of the relay 88 is open 7 and no impulses are transmitted to or'by the thyratron 8L The return of the carriage I I8 to its normal position opens the switches 82 and 85 and closes the switch 88. The electromagnet 84 is deenergized so that the drive of the screw I2I is ter- The dogs ml and I84 of the punching minated. The circuit of the motor I! through the closed switches 16 and 80 is maintained so that the motor continues to operate. The electromagnet 63 is energized so that the drum 36 is driven. The movement of the paper tape brings the first of the train of perforations just scanned by the contacts 34 and 35 into alignment with the contacts I36 and I3! so that the electromagnet I3! is energized releasing the dog I21 and closing the switch 81. Continued movement of the paper tape brings the next train of perforations, that is the seven perforations, into alignment with the contacts 34 and 35 with the result that the drive of the paper is terminated by the deenergization of the magnet 63 and the screw I2l is driven owing to the energization of the electromagnet 84. Consequently seven impulses are supplied to the stepping mechanism l6 and the actuator I! is located below the bar I l 8 corresponding to selection No. 64. The electromagnets 19 and 8 are thereupon energized with the result that the correspondingbar I8 is actuated and the switch 16 is opened thus terminating the operation of the motor Id. The phonograph motor 22 is put into operation bythe closing of the switch 2| and the phonograph operates until the recording is completely reproduced and the switch 23 is opened. As has been heretofore explained the electromagnet 26 returns the actuated bar l8 to its normal position and the actuator Il returns to its initial position.

If the operator dials up two selections by four operations of the dial Ill, four rows of perforations are applied transversely of the broad tape l2. At the end of the second dialing the switch 16 closes and the motor l4 starts drawing the paper tape to the right as viewed in Fig. 1 until the first row of perforations becomes aligned with the contacts 34 and 35. In the event that the third dialing is made while the tape is moving the drive of the tape is interrupted by the opening of the switch 60 so that the tape is always at rest during a punching operation. After the dialing the movement of the tape by the motor 14 is resumed until the first row of perforations is aligned with the contacts 34 and 35, whereupon the drive of the paper is terminated and the screw I2! is put into operation to transmit the corresponding number of impulses to the stepping mechanism IS. The tape moves again to bring the second row of perforations into alignment with the contacts 34 and 35 and again the corresponding number of impulses is transmitted to the stepping mechanism H6. The electromagnets l9 and 18 are then energized and the corresponding bar I8 is displaced so that the motor 22 is put into operation to reproduce the first selected recording. Displacement of the bar l8 energized the relay 20 so that the switch 80 is opened and the circuits of the motor l4 and the relay 63 are broken. Consequently the drive of the pickup roller 36 is terminated as long as a pin I6 is displaced. It is to be noted that the energization of the magnet 16 does not open the switch 16 since the wheel 10 has been displaced four teeth in the counterclockwise direction by the four dialing operations. When the first selection has been determined the corresponding bar I8 is returned to its initial position, the switch 80 closes and the motor I is put into operation to pick up signals from the two trains corresponding to the second selection with the result that the bar l8 corresponding to the second selection is displaced. The wheel I0 is moved back two teeth when the second bar I8 is displaced so that the motor I is rendered inoperative. After the first recording is reproduced the abutment 25 on the disc 21 cooperates with the displaced bar to determine the second recording and this bar is returned to its normal position. The phonograph motor 22 continues to operate until the second selected recording is fully reproduced whereupon the operation of the phonograph is completely terminated by the opening of the switch 23.

If the operator makes a larger number of selections, for example five, by dialing ten times, the operation is the same except that the switch 16 does not become closed until the five corresponding bars 18 have been displaced. A typical operating condition is that when the second selection is being reproduced the bar I6 of the third selection is displaced and the wheel 16 is four teeth away from its position for closing the switch 16. Consequently the phonograph operates to play the five recordings in the order in which the selections were made.

Thus the stepping mechanism 16 may be arranged for operation with one train of impulses and in this case the counter 10 is arranged so that one toothmovement from normal position closes the switch 16. The relay I8 is modified so that it returns the wheel one tooth on each actuation.

In the case three trains of impulses are employedf the stepper I6 must require three trains to make a selection. The relay 18 must return the wheel 10 three teeth each time it is energized, and the switch 16 must be arranged so that it will not close until the wheel 10 has been moved three teeth from normal positionby three energize.- tions of the relay 68.
