19 Claims. (Cl. 274-40) This invention relates to selectors for automatic phone-- graphs and particularly to phonographs which are arranged to play both sides of a plurality of records.

Such phonographs normally comprise two units, a magazine unit and a playing unit, one of which is movable into a plurality of positions, each position being individual to one record. g

A phonograph of this type is described and claimed in co-pending application Serial No. 75,100, filed February 8, 1949, by Edward F. Andrews, now U. S. Patent No. 2,581,345. In that phonograph, the magazine is stationary and a player unit orcarriage moves along the magazine and is arranged to be arrested effectively op-- posite any one of the records in the magazine which is removed therefrom by mechanism on the player arm for.

reproduction from one side, the other side, or both sides. For playing or scanning, the player. unit moves in one direction along the magazine and the scanning movement is interrupted when an electric circuit is completed between contacts on the player unit and stationary contacts. After the scanning operation, the player unit moves backwardly to its initial playing position without playing any records and the playing operation is resumed. In that machine, selections were made by means of a four-position lever or contact. Normally, the lever was in inoperative position, but it could be moved manually into a position to effect the playing of one side of a record, or into another posi ion to effect the playing of both sides of the corre sponding record, or intoanother position to effect the playing of the other side of the selected record.

The principal object or" he present invention is to provide a selector whereby selecting members, each individual to one side of each record, can be actuated into selecting position so that the scanning operation may be interrupted by a displaced selecting member or by two displaced selector members to effect the playing of one side, the other side or both sides of a selected record.

The invention is described herein in connection with the mechanism and illustrated in the aforesaid Andrewsapplication which is hereby included by reference. The present invention will therefore be described in relation to the novel selecting means including contacts and circuits and the illustration of the mechanism will be limited so as to illustrate such parts of the machine as cooperate with the switches in the new'selecting circuits.

The invention will readily be understood from the following description thereof, taken in conjunction withthe accompanying drawings, in which: 7

Fig. 6 is a fragmentary sectional elevation showing the manner in which other switches of the present invention are associated with'the mechanism;

Fig. 7 is a similar view partly in section showing the manner inwhich certain switchesof the present invention are mounted on the mechanism; and i Fig. 8 is another fragmentary view partly in. section showing the mannerin which switches of the present invention are associated with the mechanism.

Referring to the drawings, and. particularly to Fig. 2, it is to be noted that during the playing of a record, the switches P and S are both open, the. common pole being engaged by the screw 1098-on the record clampingarm see. The switch P is normally biassed to closed position. if the recordis not properly. positioned for the clamping ofa .recordin playing position, the switch. P is not open. On the other hand, if no recordis there to be clamped, the switch S closes. in both cases, as will hereinafter appear, thetrip relay is energized and the machine continues :its operation. Fig. 2 also shows the relation of the switches O and M; When the clutch 250 is disengaged, the switches O and .M are open. At all other times, that is, during record changing, scanning and return travelof the player unit, these switches are closed. These switches are suitablyactuated by anextension on the lever 276 which actuates the clutch 250.

'teferring to. Fig. .3, it is to be noted that during scanning, the switch W isclosed and the switch B is open. At all other times, these switches are'actuated into opposite relation by a pin carried by. a clutch operating. link 124;

Referring to Fig. 4, it .is to -be;noted that the switch ICis actuated by an extension on the arm 752 of the multi-armed lever 736. The switch IC is normally closed. When the machine is tripped,=the arm 7 52 opensthe switch EC and this switchis closed again t anintermediate point during the half cycle of the cams which results from the tripping of the machine.

Referring to Fig..5,.it .is to .be noted that the switch A is normally open. .The latch 796 is integral with an arm $22 which normally rests on a shoulder 8 24tofthe, switch operating lever 792. When the player arm swings the latch lever 796 at the end of the playing of arecord, the aim 822 moves off the step 824 and'the switch operating lever. 792swings in, counterclockwise direction, closing the SWitCiT'Ain the samemanner as the switcht790 was closedin the Andrews application.

Referring to Fig. 6,.switches C, IC,-U and are shown operatively associated with the *lever 590. which controls the application of the stylus of the player arm'ontothe record and its removal therefrom. These switches are more clearly shown inFig. l. .Itmay be stated that during the-playing of a record, the lever. 590 is in an upward position and switches C and ,V are closed "as shown in Fig. 1 and switches U and SC are open. At the endsof the playing of a record, the lever-590 moves downward-ly to lift the stylus off the played record and switches STCiahd U close and switches -C and. V- open. I Duringa short time in either movement of the lever59tl, both switches C and SC are closed. e

Referringto Fig. .7, it-isto be noted'that the sector gear 412 which drives the record; transfer arm,.is provided with an extensionwhich actuates the switches- E, F, D, Y and AM' The switch AM is amuting-switchgwhichis open when a record is being-played andisclofsedwhen the transfer arm begins tomove down with the played record. It openstwhen the transfer arm is nearlyiallrthe way up. When the transfer arm hasmovedaup slightly, switch D closes and when it is about a quarter ofith e way up, switch Y; opens, and-switches E ,and F open. Itis to be noted that-E opensbefore F. Whenare d is almost three-quarters returned to the magazine, the last mentioned switches move to opposite position, F closing before E.

Referring to Fig. 8, it is to be noted that an extension on the slide bar 552, which moves the player arm from the left side of a record to the right side and vice-verse, actuates the switches X, RC, LC, RL and LL. When the player arm is on the right side of a record, as shown in Fig. 8, the switches X, LC and LL are open, and switches RC and RL are closed. When the slide bar 552 moves to its opposite position, the switches are in reverse relation.

Referring more particularly to Fig. 1, the motor 150 is a reversible synchronous motor of the capacitor type, energized from the usual 110 v. lines. One of these lines, for example 21, includes a switch 22 which is closed by a relay 23 so that the motor operates as long as the relay 23 is energized. The line 21 is connected to terminal 24 of the motor and to one side of each of the switches G and K. The other power line 25 is connected through a large capacitor 27 to the opposite terminal 28 of the motor. The power line 25 is also connected to one side of an auxiliary capacitor 29 and to one side of each of the switches H and I. The common pole of the switches G and H is connected to a third terminal of the motor 30 and the common pole of the switches J and K is connected to the opposite fourth pole 31 of the motor. The terminal 28 of the motor and the other side of the auxiliary capacitor 29 are connected to the switches Y and 0. When either of these switches is closed, the auxiliary capacitor 29 is connected in parallel with the capacitor 27 to increase the torque of the motor when the player unit is scanning, returning, or performing its record changing functions. As will hereinafter appear, one or both of the switches Y and O is closed except during the playing of a record when both are open.

In Fig. 1, the switches are shown in their position during the playing of the left side of a record. Switches G and I being closed and switches H and K being open, the line 21 is connected to the terminal 30 and the line 25 is connected to the terminal 31. The motor operates in the proper direction for the playing of a left side of a record. These switches are in the same position during scanning which requires operation of the motor in the same direction.

When the reversing relay 32 is energized, switches G and .T are opened and switches H and K are closed, connecting terminal 30 to the line 25 and connecting terminal 31 to the line 21 so that the direction of the motor is reversed for playing the right hand side of a record or for return travel of the carriage. The reversing switches are locked in reverse position in the same manner as the reversing switches of the aforesaid Andrews application.

26V is connected to one side of the relay 32. Its other side is connected during scanning and playing by the switch 33 of the reversing switch 34 to a normally open switch RA, a normally closed switch LA and through switches B and E to ground. Consequently, energization of the reversing relay 32 for the playing of the right side of a record requires switch RA to be closed, switch LA to be closed and switches B and E to be closed. E is closed during scanning, being closed when a played record is about three-quarters of the way back into the magazine and remaining closed until another record is moved up about a quarter of the way from its position in the magazine. The switch B is open during scanning. Consequently, during scanning, the reversing relay 32 cannot be energized. The switch RA and also the normally open switches RB and RT are closed when the right side relay 35 is energized. The normally closed switch LA is opened and the normally open switches LB and LT are closed when the left side relay 36 is energized. During play and scanning, a switch 37 of the reversing switch assembly is closed and supplies 26V to one side of the right side relay 35, the left side relay 36 and the trip relay 38. At the end of the scanning, the reversing switch 34 is thrown so as to open the switches 37 and 33 and close the switch 39. Closing the switch 39 grounds the right side of the reversing relay 32 so that it is energized and the motor is reversed to move the carriage back to normal initial position. During this return of the carriage, the switch 37 being open, the trip relay 38 and the right and left side relays 35 and 36 cannot be energized. At the end of the return movement of the carriage, the reversing switch assembly is returned to its condition shown in Fig. 1, deenergizing the relay 32 so that the motor reverses and drives the carriage in the opposite or scanning direction.

The other side of the right side relay 35 is connected to one pole of the switch RB and to a contact 40 on a slider block 41 which moves with the carriage. The other side of the left side relay is connected to one pole of the switch LB and to a contact 42 carried by the slider block 41. The slider block 41 moves over two sets of grounded armatures 43 and 44. In normal condition, the armatures 43 and 44 are out of the path of the

contacts

40 and 42, but when one or more of them is displaced into actuated condition, it is engaged by its

appropriate contact

40 or 42. The armatures 43 and 44 are arranged in opposite pairs and these pairs have the same spacing as the record spaces in the magazine. One armature 43 of a pair corresponds to the right side of a record and the opposite armature 44 corresponds to the left side of the same record. If one of the armatures 44- is in actuated position, then it is engaged during scanning by the contact 42 and the left side relay 36 is energized, its circuit being completed through the closed switch 37, the relay 36, contact 42 and actuated armature 44 to ground. The energization of the left side relay 36 opens the switch LA and closes the switch LB and LT. The closing of the switch LT completes a circuit from ground, switch W, which is closed during scanning, line 45, trip relay 38 and switch 37 to 26V supply. Consequently, the trip relay 38 is energized arresting the scanning drive and moving the corresponding record up for playing. The carriage is properly located for the playing of the left side of the record in the manner described in the Andrews application referred to. The closing of the switch LB completes a holding circuit for the relay 36 as follows: 26V, switch 37, left side relay 36, switch LB, switch F to ground. Switch F is closed during scanning and it opens after the record has been lifted up about a quarter of its travel. When that occurs, the relay 36 drops out. It is to be noted that after the contact 42 engages the grounded actuated armature 44, the contact moves clear of this armature slightly as the carriage comes to a rest and is positioned accurately for cooperation with the I selected record. This positions the plunger of a solenoid 46 on the carriage 41 in alignment with the arresting armature 44. A similar solenoid 47 is arranged for cooperation with the armatures 43. The solenoids 46 and 47 are connected to a switch SC, connected to a switch C, and connected to a switch IC to ground. The

other side of the solenoid 46 is connected to a switch LC and the other side of the solenoid 47 is connected to one side of a switch RC. The common pole of the switches LC and RC is connected to the 26V supply. When the player arm is in position for the playing of the left side of a record, the switches X, RC, LC, RL and LL are in the position shown in Fig. 1. Consequently, during the playing of a left hand record, 26V is supplied to a lamp 48 to illuminate it. The switch LC applies 26V to the solenoid 46 and this solenoid therefore becomes energized to return the actuated armature 44 to its normal position when switches SC. C and IC are closed. During scanning, the switch SC is closed, switch C is open, switch U is closed and switch V is open. As the player arm is applied to the record,

simultaneously and otlf t Switches V and C close and switches U and SC open. For a brief'time both switches C and SC are closed and at this time switch IC is closed so that the solenoid 46 is energized to return the arresting actuated armature 44 to its normal position. Switch IC opens immediately each time the trip relay 38 is energized and closes at an intermediate portion of the half cycle of the cams initiated by the trip relay. Consequently, it is closed when the switches C and SC are both closed momentarily as the player arm is being applied to the left side of the selected record. At the 'end of the'playing of the record, switch A is closed momentarily completing the circuit ground, switch A, line 49, switch V, line 50, trip relay 38, switch 37 to 26V. The switch IC is immediately opened and promptly thereafter as the player arm is being lifted off the record, the switch SC closes. But the solenoid 46' is not again energized because switches C and SCare both closed momentarily dur ing the early part of the half cycle operation of the cams and before switch IC has been closed again. The record is returned to the magazine and the scanning by the playing unit is resumed.

If the next armature in actuated position is one of the right side armatures 43, then the engagement of the actuated armature 43 by the contact 49 completes a circuit from ground, armature 43, contact 443, right side relay 3S, switch 37 and 26V. The right side relay being energized, closes the switches RA, RB and RT. The closing of the switch RT completes a circuit from ground, switch RT, switch W, closed during scanning, line 45, trip relay 38, switch 37 to 26V. Thus, the trip relay is immediately energized and the player unit is arrested for proper cooperation with the record corresponding to the arresting armature 43. Switch W immediately opens and switch B closes. relay 32 is now energized by the following circuit, 26V, relay 32, switch 33, switch RA, switch LA,line Si, switch B and switch E. Switch E opens before switch F and after the selected record has been moved up about a quarter of the way. Consequently, the circuit is completed to ground, immediately B closes and immediately after the trip relay 38 is energized. Switch RB completes a holding circuit for the right side relay 35 as follows: 26V, switch 37, right side relay 35, switch RB and switch U to ground or switch X to ground. This holding circuit remains established until both the switches X and U open. The motor being driven in the direction to play the right side of a record, the player arm is moved across to the right side of the record and the player arm shift bar opens the switches X, LC and LL and closes the switches RC and RL. This applies the 6V to the lamp 52 and connects the 26V supply to the solenoid 47 to condition it for actuation to return the arresting armature 42 to normal position. The switch U is opened as the stylus is being applied to the record, thus breaking the holding circuit for the relay 35 which drops out. The reversing relay 32 is deenergized, but the reversing switches G, H, I and K are mechanically locked to drive the motor in the right side playing direction in the manner described in the aforesaid Andrews application.

C closes and the following cancel circuit is completed: 26V, switch RC, cancel solenoid 47, switch SC, switch C and switch IC to ground. As previously noted, the switch IC opened on the energization of the triprelay and closed during the ensuing half cycle off-the cams so that it is in closed condition at the moment that both switches C and SC were closed. This cancel circuit is interrupted by the opening of the switch SC as the stylus is being applied to the right side of the record.

When opposite armatures 43 and 44 areactuated calling for the playing of both sides of a single reicor'dh'en during scanning, both contacts a The reversing 3" game "RA is closed, switch LA is open.

lays 35 and 36 are energized. The trip relay is actuated broken by the opening of the switch W. The reversing relay 32 is not at this time energized because while switch The cams go into their cycle to play the left side of the record and this playing is completed before the reversing relay 32 is energized. The left side relay is locked up through the circuit 26V, switch 37, left side relay 36, switch LB and switch to ground. The right side relay 35 is locked up through the circuit 26V, switch 37, relay 35, switch RB and switch U to ground. It is to be noted that the switch 'X'is open since the player arm last played the right side "of a record. The motor being driven in the direction applied to the record. The lamp 48 is illuminated and 26V is applied to the solenoid 46 to condition it for the return of the displaced arresting armature 44 to its nor- :malposition. The solenoid 46 is energized as the stylus is being applied to the left side of the record, the switch C closing and completing the cancel circuit through the switches C, SC and IC. As noted before, the switch IC is closed during the latter portion of the half cycle of the Iii) As the stylus is being applied on the record to be played, the switch closed at all times except during scanning.

E opens before the switch F. The switch LA closes, but 1 the reversing relay 32 is not energized because its ener- 'gizaticn requires both switches B and E to be closed. The swi ch E closes when the transfer arm is about threers back towards the magazine. When switch E is 'thus closed, the circuit of the reversing relay 32 is completed so that the motor starts working in the opposite direction and the record is returned to the player unit for the playing of its right side. The reversing switches G, H, J and K are mechanically locked up as previously described and the machine operates to play the right side of the record and return it to the magazine. The right side relay 35 becomes deenergized after the reversing relay 32 has thus been deenergized, by the opening of both the switches U and X. Switch X is opened when the player arm is moved to the right side of the record and the switch U is opened just before the stylus is applied to the record. Before both these events have taken place, the reversing relay 32 has been energized and the reversing switch is mechanically locked up for playing the right side of the record. After the playing of the record is completed on both sides and is returned to the magazine, the mechanical lock on the reversing switches is removed just as the machine goes into scan so that the direction of the motor is reversed and scanning occurs in the proper direction.

The armatures 43 and 44 are arranged to be attracted into actuated or selecting position by electromagnets 53, there being one electromagnet 53 for each armature. Each electromagnet 53 may be individually energized to effect the playing of the corresponding individual side of a record. As many electromagnets may be energized as desired to effect the playing of a sequence of recordings. Suitable means for energizing any desired number of electromagnets 53 are shown and describedin patent application Serial No. 127,458, filed November 15, 1 949 by Albinus G. Bodohyiiow'U-SPatent' No: ,'624,'795,-and patent applications SerialE'N'os.117,389, ow USf Patbaris '1949,res ctive1y: 'rhe'e e I g t re ppetite rdws' otra'rrsa esmite teeth magnets being directed inwardly towards the armatures 43 and 44. The upper member 55 of the frame 54 is a strip of insulation provided with openings 56 through which the upper ends of the armatures 43 and 44 project. On its underside, the strip 55 carries two metal bars 57 which are connected by a conductor 58 to one side of the play control relay 23 and to the ungrounded side of the switch D. 26V is applied to the other side of the play control relay 23 so that when the switch D is closed or one of the strips 57 is grounded, the motor is in operation. Between the two armatures is located a strip of metal 59 which is of slightly greater thickness than the bars 57. The armatures 53 and 44 are shouldered to provide supports for metal washers 60. The lower ends of the armatures 4-3 and 44 are reduced and received in openings in the bottom of the frame 54. Individual springs 61 on each armature engage the bottom of the frame 54 and also shoulders on the armatures so that these armatures are biassed upwardly. When one of the armatures is in non-actuated postion, as shown on the right hand side of Fig. 1, its washer rests solely against the strip 59. While an armature has been moved to actuated position by its electromagnet 53, as shown on the left hand side of Fig. 1, its washer projects across one of the bars 57 and the strip 59. The strip 59 is grounded so that when any one of the armatures is in actuated position, the line 58 is grounded, the play control relay 23 is energized and the switch 22 is closed, putting the motor into operation to scan and play a selected record or records.

The switch D is biassed so that it is opened only when the transfer arm is returned nearly all the way and the returned record is in its normal position in the magazine. The switch D is closed during the playing of a record. As long as any armature 43 or 44 is in actuated position, the motor remains in operation. When the last selected record is on the turntable elements and about to be played, the last displaced armature is returned to inoperative position, but the switch D being closed, the motor continues to operate to play the last recording and when this last recording is played and its record is returned to the magazine, the switch D opens, the play control relay 23 is deenergized and the switch 22 opens. The machine remains out of operation until one of the electromagnets 53 is energized, again energizing the play control relay 23.

The slider block 421 is carried by the player unit and rides on slide 62 mounted on the upper member 55 of the frame 54. The lamp 4% is illuminated when the left side of a record is being played and the lamp 52 when the right side of a record is being played. These lamps are carried by the player unit and cooperate with individual sets of windows which bear indicia such as A1, A2, B3, C9, which identify the recording being played. These windows are similar to those designated 1056 in the aforesaid Andrews application.
