12 Claims.
This invention relates to certain new and useful improvements in automatic selective phonographs.
It has for one of its objects to provide a selective phonograph which is so designed and constructed as to automatically play both sides 'of the record pre-selected for play.
Another object of the invention is to provide a phonograph of this character having means for supporting a plurality of-records in such a manner that they can be selectively moved to vand from a storing position .whereby they are projected to an automatically-adjustable mechanism that presents them to and from a record-play position and further that they can be presented to play either one side or the other of the record,
-in accordance with the selection made.
Other features of the invention reside in the construction and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

Similar characters of reference indicate corresponding parts throughout the several views'.v
In its general organization, this automaticl phonograph which is primarily designed to selecof the records, comprises a turntable which is adjustable vertically to and from a play position, a. reproducing unit, a shiftable record magazine disposed at one side of the turntable for adjustment to one or another of a plurality of selective positions, a record holder operable between the magazine and the turntable and adapted for combined vertical and swiveling movements to position one side or the other of therecord on the turntable for play, means interposed between the magazine and record holder for transferring the record from the magazine to the holder and vice versa, means for selecting in advance one or more records desired for play, means governed. by said selecting means for selectively controlling the swiveling of the recordV holder in accordance with the record selected, means for elevating the turntable to lift a selected record clear of the record holder into operative engagement'with the reproducer,` and power driven means for actuating the aforesaid mechanisms in their proper cycle of operation to automatically play the records selected, whether the record-selections chosen be on one side or the other of the records.
Referring now to the drawings, the numeral i5 indicates a supporting platform or frame upon which the working parts of the phonograph are mounted. The turntable I 6 is mounted on a veradjustable rotatablespindle l1 which extends below the platform and is feathered on a driven sleeve I8 connected by a worm wheel I9 and worm 2li withan electric motor 2i. The turntable runs constantly during such time as the l motor circuit is closed.
Disposed at one side ofA the turntable and adapted for selective horizontal `adjustment; is a record m'agazine 22 comprising upright, segmental-shaped partitions or plates 23 suitably record-receiving pockets 2l closed at their bottoms and outer sides by walls while their inner sides are open for the discharge and return of the records from and to the magazine as shown in Figures 1, 2 and 5. These partitions are secured at their lowerends to a yoke 26 which extends downwardly through an opening in the platform i5 and i's guided for horizontal movement in a bracket 25e depending from the underside of the platform.
The adjusting movements of the magazine to record selective positions, prior to transferring the records to a play position upon the turntable, is preferably constructed as follows:
Fixed to the sleeve it between the platform l5 and motor 2i is a pinion 2li which is oonstantly rotating as long as the motor circuit is closed. Adapted to be brought into and out vof engagement with this'pinion at predetermined times in the cycle of operations is a driven gear 25:8 journaled on a stud 2d mounted at one end of a horizontally-swinging lever Sil fulcrumed intermediate its ends on a vertical stub shaft 3i journaled in a depending bracket 32 xed to the platform The actuation of this lever into and out of an operative position is controlled at predetermined times by a pair of solenoids 3de.
and tdi as shown in Figure 6.
integral with the gear 2t is a pinion 33 which meshes constantly with a gear 3d fixed on the stub shaft @it immediately below the lever dil, as shown clearly in Figures 6 and l2. 0n the underside of or constituting a part of the gear 3d is a gear segment or arcuate rack 35 for intermittent engagement with a gear loosely mounted on a stud Sil also secured to the braclret 32. Adapted for coupling or clutching engagement with the gear 36 during a counter-clockwise movement thereof is a spring-pressed pawl 3d pivoted to Aan arm 38a applied to a notched ratchet wheel @d mounted below the gear 'dd on the stud 3l. Connectedto the ratchet wheel at it is a crank arm di which is in turn connected to the yoke E@ to impart a horizontal movement thereto. In clutching engagement with the 'has been selected.
ratchet Wheel S9 is a, spring-pressed retractable dog i2 mounted in'the bracket S2 and having an upstanding pin it thereon which is engaged by a cam plate de depending from the underside of the gear 3d and whose leading edge is in advance of the gear segment 35 during a clockwise movement. lt will be seen that, when the lever 3b is movedl in a direction so that the gear 23 is in mesh with the pinion 2l, motion is transmitted to the gear 3ft, its segment tiand cam plate Gili, the latter engaging the pin l of the dog di to disengage the dog from the ratchet wheel BQ to free the latter and gear 3G so that the leading end of the segment upon striking the arm Bda moves it and the pawl-engaged gear 36 a fraction of a revolution in a' counter-clockwise direction until the teeth of the segment engage such gear Se at which time the latter and thel ratchet wheel 39: are driven by such segment 35 to .operate the crank arm di and thereupon move the magazine 22 horizontally to a predetermined selected position. The cam plate lift is of such a length that during such movement of the magazine, it maintains the dog d2 disengaged from the ratchet wheel-3Q. At a predetermined time in this magazine-adjusting cycle, the cam plate dit envases other, one row of pins selectively controlling the presentation of the records on 'one side and the other row of pins selectively controlling the presentation of the record onr the opposite side. These pins are slidingly mounted forhorizontal movement in a block d6 secured to the bracket 26a as seen in Figure 5. At one end each pin has an enlarged head il and at the opposite end has a pinl which limits its movement to a projected selective position. The projecting movements of these pins to a select position is accomplished by a double-armed trip or actuating member l fixed adjacent the inner end of a longitudinally shiftable and oscillatory rod 5i mounted in bearing-brackets d2 as seenin Figure 6. At the outer end of the rod is a control knob 53 which is adapted to be grasped by the patron and shifted axially to bring its trip Imember t@ to a predetermined position opposite a given pair of selector pins t5, and then rocked in one direction or the other to project one or the other of the registering pins to a selective governing position. To insure the patron that he has actuated the correct selector pin, an escutcheon plate 55 is pro-` vided with notches 55 arranged in' two rows and numbered to correspond to the number of records in the magazine, the even numbers designating, say, the rear side of the record and the odd numbers the front side.of the record, viewing the magazine from the front side of Vthe phonograph. Connected to the rod and in operative relation with these notches is a double armed lever 5E which operates in the saine manner as the member 5@ and when one arm or the other of the lever enters a notch that record In the position shown in Figure 6, the eighth record in the magazine and the rear side thereof has been selected for play. Pivoted to a substantially U-shaped bar 5l carried by the magazine-bracket 2d and adapted to .rides off the dog-pin 63 and the dog d2 is autotravel therewith are upper and lower verticallyswinging dogs iid which are common to the companion upper and lower rows of selector pins de and which, at predetermined times during a selecting cycle, are adapted to engage one or u another of the projected pins during the forward travel of the magazine to arrest the latter in a select position. On the rearward movement of the magazine, these dogs are adapted to swing upwardly from contact with the pins and ride over them, a stop pin 59 being associated with each dogV to limit its downward swinging movement.
When the" magazine has been arrested in a selected position, means are provided for transferring that selected record to a.' record holder whereby it is deposited onto'the turntable for play. To this end, I provide a vertically-swinging transfer arm t@ pivoted at 6i adjacent the rear side of the platform IS and terminating at one end in a substantially U-shaped portion t2 which is adapted to register with one or another of the magazine-pockets 2d and eject the records therefrom, while its opposite end is adapted to eject a played recordv from the record holder for transfer back to the magazine, the record rolling by gravity-during itst@ common to allof `the pins and intermediate its endsv ord from the magazine by gravity is accomplished by a substantially L-shapedvertically swinging pick-up arm 64 in bearing contact with the arm 6.0 and fixed at 65 to one end of a rock shaft 66 journaled in the upper end of a hollow post 61 rising from the platfor-m adjacent the magazine 22. Fixed to the other end of the rock shaft is an arm 66 connected by a link 69 to the upper end of a vertically-shiftable pitman slidingly mounted within the post and operatively connected at its lower end to the outer end of a vertically-swinging lever 12 pivoted intermediate its ends `at 13 at a point below'the platform I5. 'Ihe inner end ofthe lever 12 preferably terminates in an actuating portion 14 which bears against a cylindrical cam 15 constituting a part of a master cam 16 fixed to 'the lowerend of the stub-shaft 3|, as shown in Figures 3 and 4, and adapted to rotate with the gear 34. After the magazine 22 has been selectively positioned in the manner heretofore described, the cam 15 comes into operation to rock the lever 12 in a direction to elevate the pitman 10 and thence rock the pick-up arm 60 vertically into the registering magazine-pocket to eject the record therefrom and direct and transfer it by gravity to the record holder means presently' to be described. After the record is played, it is returned from the record holder means to the magazine by effecting a pivoting of the pick-up arm in the opposite direction which lifts the record from the holder means and causes it to roll by gravity to the magazine. l
l The record holder vmeans is operatively disposed between the turntable and the magazine and is designed to receive the selected records from the magazine and deposit them onto the turntable for playing on one side or the other in accordance with the selection made. To this end, the record holder is preferably in the form of a channel-shaped ring 11 pivoted to swing vertically to and from an operative position over the turntable, as well as to swivel or oscillate to present one side or the other of a record over the turntable, and having approximately half of its peripheral wall, or that portion opposite the magazine, cut away to form a slot or opening 16 for the passage of 'a record to and from the magazine. It may be stated here that the width of the record-receiving space' in the channeled ring is such that when the ring is operatively disposed over the turntable, and the latter is raised to its playing position, the record is free to revolve within the holder without contact .therewith, as shown in Figure 3. As shown in Figures 1 and 5, therecord-receiving ring 11 iswivelly supported at 19 at diametrically opposite sides and in the axial plane of the turntable in a vertically-swinging frame or carrier 90 fixed at its inner end to a horizontal shaft 8| journaled in suitable brackets 82 rising from the platform I5 to the rear of the turntable. This shaft is adapted to be driven through an arc of approximately 90 to and from a playing position over the turntable and for this purpose may be pro- Y vided with a chain and sprocket drive 99 connected to a shaft 64 which is adapted to be driven at predetermined times in 'one direction or the other through the -me'dium of Aa 'gear segment 86 and vertically-swinging rack I6 pivoted at 81 below the platform I6 and operatively connected above its pivot 69 having a roller 89 engagement with the periphery of a cam 90 mounted on the shaft 3| for shifting the actuating link in a directiony to turn the shaft kII clockwise, viewing Figures 3 and 4, to bring the record holder from the position shown in Figure 3 to the position shown in Figure 4. For the purpose of turning the shaft 02 in the opposite direction and swinging the holder from the position shown in Figure 4 to that shown in'Figure 3, a cam-groove 9| is provided on the cam 90 which is adapted to engage the roller 89 of the link 88 at a predetermined time in the cycle of movement of the cam. A spring 92 may be provided for resisting movement of the holder out of its normal upright position and a rest 93 may be provided to support the holder in its play position over the turntable.
' As lshown in Figures 1 and 5, the inner end of the pick-up arm terminates alongside the swiveled end of the carrier-frame 60 and its holder 11 and has a pin 6|)a thereon adapted to extend between such parts and through a notch 60b formed in said holder for engaging the peripheral edge of a record vand directing it onto the pick-up for return to the magazine.
When the record holder is swung downwardly over the turntable, the latter is below and spaced from the record, and means are provided for raising the turntable to a height whereby the record is picked up from supporting engagement with the holder-ring 11 and deposited on the turntable for play, with the record free to revolve within but out of contact with the holder. To this end the turntable-spindle I1 rests at its lower end on one varm of a vertically-movable bell crank 94 pivoted at 95 to a post 96 extending below the platform I5. The other arm of a bell crank is connected by a link 91 to one end of a horizontally-swinging tappet lever 98 pivoted at 99 to an arm |00 radiating from the post 96, the other end kof said tappet'lever engaging a pin |0| projecting from the underside of the master cam 16. It will be seen that upon rotation of the cam in a clockwise direction, viewing Figure 7, that the pin will encounter the tappet lever 98v and in turn, through the link 91 and bell crank 94, raise the turntable to its proper playing elevation, shown in Figure 3. A spring |02 connected to the bell crank acts as a cushion when the turntable is lowered.
Prior to the raising of the turntable I6 into a play position, the reproducer |03 is swung horizontally so that its needle is directly over the to an actuating link or rod at its free end disposed forsound groove of the record and then lowered onto the record for play. To this end, the reproducer or tone arm is pivoted at |04 toa horizontally-swinging bracket |06 supported on a sleeve |06 extending downwardly through a hollow post or standard |01 rising from the platform I 6. Engaging the tone arm forwardly of its pivot is a spindle |06 which is guided for vertical movement in the sleeve |06 and rests at its lower-end on the hub of a two armed adjustable member |09 supported at the outer end of a vertically-swinging rock lever ||0 pivoted intermediate its ends at III and having an upward-extending lug II2 at its inner end for engagement with a recess I|3 in the underside oi' the master cam 16. At a predetermined time in the rotation of the cam the rock lever ||0 is displaced vertically by reason ofthe lug ||2 entering into the recess III to in turn lower the spindle |08 from contact with the tone arm and allow itto drop by gravity onto` the record aboutl its pivot I 04 during a selecting cycle. During the playing of the record the cam 16 is at so that upon completion of a record-play a reversal of the movements just described takes place and when the cam is again rotated, the lever is rocked to normal position and the tone arm elevated clear ,of the record.
The horizontal movement of the tone arm, after play, to a normal non-play position at one side of the turntable immediately after the tone arm has been raised from contact with the record, is initiated by the master cam 76 through the medium of a depending lug Ilfl in contact with the cam and disposed at one end of a horizontallyswinging llever ||5 pivoted intermediate its ends at i I8 and having its other end engaging an abut- 1 ment bar IH extending between one arm H8 of the two-armed member |09 and a crank arm H9 fixed to the lower end of the sleeve |06, as shown in Figure 7.. After the record has completed play, the cam is set in motion as previously described to rock the lever ||5 in a direction so that its outer end engages the abutment bar and swings the tone arm to one side of the turntable. A leaf or fiat spring |20 disposed in the path of travel of the abutment bar I |1 serves to swing the tone arm into a play position over the .record immediately after the lever ||5 is actuated by the cam 'i6 away or free from contact with such bar.
Means are provided for controlling the swiveling movement of the record holder or ring 'il about its trunnions' to present one side or the other of the selected record into play position upon the turntable. The swiveling movement of the holder in one direction or the other takes place during the vertically-swinging movement of the holder toward and from the turntableand is through an arc of 180, being accomplished by a bevel gear |2| fixed to the inner holder-trunnion 'I9 and meshing with a like gear |22 constituting a part of a rock arm |23 freely mounted to turn on the shaft 8| and having a lug or shoulder ille at its free end for latching engagement with a laterally-swinging spring-urged pawl |25 pivoted to one end of a lever |26 fulcrum'ed intermediate its ends at |21. The other end of this lever is operatively associated with a pair of opposing solenoids |28 and i29 for shifting said lever into and out of latching engagement with the shoulder |24. When the solenoid |28 is selectively-energized to play one side of a given record, it actuates the lever b|26 in a direction to bring its pawl |25 into latching engagement with the lug lZt -of the arm |23, as shown in Figure 9. It will be seen that, when the arm |23 is held from rotation by the pawl |25, the bevel gear |2| carried by the holder will ride over the companion gear |22, during the lowering of the holder, to swivel the holder about its trunnions throughy an arc of 180, and thereby expose the chosen side of the record for play. When the arm |23 is unlatched from the 'lever |26, as when the companion solenoid |29 is energized when selecting the opposite side of the vrecord for play, said arm will turn with the shaft Si, thus performing no swiveling action to the record holder during its lowering and raising movements.
During the selecting cycle of operations, that is, the adjusting movement of the record magazine 22 to a given record-selecting position, the transfer of the selected record from the magazine l'to the holder-ring 1l, the deposit of the record in the'holder-ring to a position over the turntable to play one side or the other of the record, the elevating movement of the turntable It into en gagement with the record to be played; and the horizontal and vertically-swinging movement o agences thel tone arm into playing engagement with the starting groove of the recordthe gear train and cam elements are in driving engagement with the motor-pinion 2i so that the several parts of the record-selecting mechanism are automatically actuated in predetermined sequence. 'when these various parts are in readiness to play the selected record, then the gear train and cam elements areautomatically disconnected from driving engagement with the motor-pinion and remain -at rest during the playing of the record. After the playing of the record has been completed, then means are provided, which are governed by the tone arm, for again automatically connecting the gear train and cam elements into driving engagement with the motor-pinion tov cause a reversal "of the cycle of operations for returning the played record to the magazine and restoring the other parts to initial position, after which the same cycle of operations is continued for playing the next selected record. The automatic clutching anclunclutching of the gear train and cam mechanism of the record-changing mechanism at predetermined times may be controlled electrically by means which are preferphonograph, and in this connection the switch l' may be manually operated or it may be coincontrolled in any approved manner. The solenoid 30a and the solenoid bb are adapted to be energized at predetermined times to automatically shift the lever 3 in one direction or the other to bring the gear t@ into or out of driving engagement with the motor-pinion 2l and foi-this purpose the solenoid :ita which governs the shifting of the lever 3i) in a direction to engage the gear 28 with the pinion 27 is controlled by switches E33 and i3d, respectively, the switch i355` having one of its terminals connected by a wire 35 with one endy of the coil of the solenoid Sita, the other end of such coil being connected by a -wire |35 with the lead wire 39, while the other terminal of said switch |33 is connected by a wire i3? with one of the blades i3@ of the switch i3d. This last-named switch includes aV movable biade 539 operatively .associated with the companion solenoid 30h, and an intermediate xed blade it which is connected to the lead |33 Leading from the blade |39 oi the switch |3-3 is a wire Mii which is connected to one of the terminals of an associated switch id?, a companion terminal thereof being connected by a wire M3 with one end oi the coil of the solenoid 331), the other end of the coil of the latter being connected to the wire iBE vleading to the lead wire 93B. The respective movable blades i3d, |39 of the switch i3d are con spectively, with the intermediate element i60 of said switch i3d.' When the phonograph is in playing position, the lever i'is in the position shown in Figure 8, with the gear 2S out oi' driving engagement with the motor-pinion 27| and the switch-blade it@V in contact with the switch blade |40, while the companion switch-blade |39 is open so that the circuit of the solenoid 30a is ready to be closed when the switch |33 included.
in the circuit thereof is closed. This switch |33 is normally open and is adapted to be closed when the tone arm |03 reaches the end of play of a record through the medium oi' a 'horizontallyswingingarm |41 which turns with the horizontally swinging movement of the tone arm and which is provided at its outer end with a projection |48 disposed in the path of the switch |33 so that when the tone arm reaches its inward position, said projection will close the switch |33 and thereby complete the circuit which will effect the energization of the solenoid 30a and automatically cause the lever 30 to be rocked to the position shown in Figure 13, and wherein the gear 28 is in driving engagement with the motor-pinion 2`| to thereby cause the operation of the record Y changing mechanism to restore the played'record back tothe magazine as well as to eiect the movement of the tone arm outwardly to aposition at one side of the turntable. In this position of the lever 30, the switch-controlling element |44 has caused the switch-blade |38 to be opened and the companion switch-blade |39 to be moved in switch-closing engagement with the switch terminal |40 to partly prepare the circuit ofthe companion solenoid h engagement with the next record selected for play. The complete establishment of the circuit for rendering the solenoid 30h operative to actuate the lever 30 in the direction to disengage the gear 28 from the motor-pinion 2'| the switch |42 is closed. The closing of this switch is controlled during the vertical movement of the tone arm onto the record, and for this purposethe two-armed member |09 has an arm |49 which is adapted to register and overlie the upper terminal of the switch |42 when the tone arm is in proper register with the starting groove of the for closing when the tone arm has been again brought into playing takes place whenv j position to unlatch record, so that when the tone arm is caused to be lowered by the cam-governed lever ||0, said arm other of a record for play includes a switch unit which is carried by the magazine 22 and which in one of two positions governing the selective side of the record to be played controls the closing of the circuit including the solenoid |28 to play such side of the record selected, and
which is operatively disposed for actuation to the other of its selective governing positions `by one or another of the projected selector pins 45 in a given row, say, the lower row, so that `when such switch unit is actuated by contact with a projected selectorpin in the lower row it will automatically shift the switch tov such other position to control the circuit of the solenoid |29 to insure the playing of the record on the other side selected. 'I'his switch unit may be in the form oi' a mercury switch which is pivoted for verticallyswinging movement lengthwise of the y.row o! selector pins tothe depending yoke 26 o! the magazine 22, and which terminates at its upper end in a trip arm |6| arranged to engage any projected selector pin in the lower row oi pins for rocking the switch unit from one normal switchl to the terminal |62 i companion solenoid 5 closing position to the other switch-closing position. A spring |52 connected to the switch arm |5| normally urges the switch |50 to a position for energizing the solenoid |28, while in its other or pin-tripped position it closes a circuit to the |29. As shown in .Figure 13 of the. drawings, the normally closed switch contacts A of the mercury switch are included in a circuit including a wire |53 leading from one of the contacts and connected to one end of the coil of the solenoid |28 and a wire |54 connected to one of the terminals ofA a transformer |55, the other terminal thereof being connected by a wire |56 to the companion switch contact. One terminal of the other set of switch contacts B of the mercury switch is connected to the transformerconnected wire |56 having a branch |51 leading to one end of the coil of the companion solenoid |29, the other end of such coil being connected by the wire |54 with the companion .switch terminal. Normally the mercury switch is held by the spring |52 in a position closed across the contacts A wherein the circuit is completed through the solenoid |28 to effect the latching of the lever |26 with the gear-arm |23-so as to compel a swiveling movement to the record holder ring during the record-selecting operation so as to play the front side of the record, that is, the side of the record which faces the patron when standing at the front of the machine (Figure 2). The playing of the records on the front side is governed by the top row of selector pins, the trip arm |5| of the switch |50 clearing such row of pins. When any one of the lower row of selector pins is projected, they are in the path oi travel of the trip arm of the mercury magazine is arrested at a selectivev station the switch is tripped to the position shown in Figure 13, wherein the switch is closed across the contacts B to effect the energization of the solenoid |29 and accordingly shift the lever |26 to a it from the gear-arm |23 and allow the holder-ring to merely swing downwardly without a swiveling action to present the rear side of the record, that is, the side of the record facing away from the patron when standing at the frontof the machine.
. At a. predetermined time in the cycle of recordchanging operations, say, at the end of play of a given record, a meansis provided for cancelling the selector pin companion to that played record.
. r this purpose, u pair of upper and lower cancelling solenoids |58 and |59 are mounted on the depending magazine-yoke 26 and are disposed common to and in opposing relation to the companion rows of selector pins 45, so that upon the energlzation of a given'solenoid its plunger causes the retraction or restoration of the alined selector pin to its initial non-selecting position. One end of the coil of' the upper solenoid |58 is connected by a wire |60 with the transformer |55 while the other end of such coil is connected by a wire |6| of a normally open switch, such terminal being selective travel of the selector pin actuating member 50, the other terminal |63 of such switch being borne by the top portion of said actuating member to eilfect the closing of this switch when the selector rod 5| is rocked to the right viewing Figures 5 and 13. The movable switch terminal I 63 is connected by a' wire |64 to one terminal of a normally-open second switch |65, the other terminal thereof being connected by a wire |66 with the transformer. The lower solenoid |59 has one end of its coil connected by a wire |61 to the switch so that when the disposed along the path of transformer 55 while the other end of the coil is connected by a wire 63 to one terminal oi the switchai. `The latter is disposed adjacent the cam lo and at a predetermined time after the playing of a record,a pin its on this cam encounters and momentarily closes this switch it to close the-circuit of the solenoids i@ and ld to eiect the lcancelling operation. When the selector rod i's s et with its pin-actuating member 5t rocked to the right, as when selecting the front side of a record for play, the alining selector pin 45 is not only projected to a select position but the switch 162, |83 is closed to. place the cancelling circuit including the solenoid ld in readiness to be completely established by the closing of the switch it.
