Mitchell, Dallas, Tex., assignor to The Rudolph Wurlitzer Company, a corporationof Application August 12, 1937, Serial No. muss 23 Claims. (c1. 274-) This invention relates to certain new and useful improvements in automatic phonographs.

It has for one of its chief objects to provide a multi-selectivephonograph which is so designed 5 and constructed as to automatically play both sides of the records, that is, play the records pre-selected, whether or not the program-selec- "tions are on one side or the other of the records.- Another object of the invention is to provide 0 a phonographof this character having means for supporting a plurality of records in such a manner that they can be selectively projected to and from a record-play positionrand further, that they can be presented to play either oneside or the other of the record, in accordance with the selections made. I

A further object is to provide a phonograph having a simple and compact record holder or magazine together with positive and effective means for bodily shifting or tilting such magazine to present one side or the other of a given record selected for play.

A still further object is the provision of an automatic multi-selective phonograph adapted to play both sides of the records and including a tiltable record-carrier stack or magazine designed to project or swing the carriers to and from a record-play position, in combination with means for releasably latching the carriers against movement or displacement out of the stack during the bodily-tilting movement of the stack or magazine to pre-set the mechanism to play one side or another of the records in accordance with the selections made.

In its general organization, this automatic phonograph which is primarily designed to selectively play both sides of disk-records, comprises the usual turntable and reproducing unit, an oscillatory or swiveling record-carrier frame or reversible magazine disposed at one side of the turntable and having a stack or plurality of superposed record-carriers therein for individual projection therefrom into and out of a positionover the turntable for effecting the playing of the 20 records, means for simultaneously selecting in advance one or more record or program selections desired for play, means governed by said selecting means for selectively controlling the revers- I ing movement-of the record-carrier frame and the 25 projection ofthe carriers therefrom in accordance with the pre-selections made, means for elevating the turntable to lift a selected record 7 from its carrier into operative engagement with the reproducer, and power driven means for actuating the foregoing mechanisms in their proper cycle. of operations to automatically play Patent No. 2,002,236, dated May 21, 1935, whereina patron may preselect in advance a plurality of records desired to be played, from the program of records to be played as borne by. one side of the records, and thereafter, upon the deposit of the proper number of coins, the phonograph will operate automatically to play the desired records which were preselected. Specifically,-the phonograph disclosed in the Wilcox patent includes a plurality of record carriers disposed in stack-like fashion at one side of a vertically-reciprocable turntable and adapted, individually andselectiveo lyi to swing laterally fronia normallnoperative x pbsition a e ase i the turntable-- o erative *position hveri sw m the path of-"the turntable enableftlie glatter, 1 when' elevateda bring it into operative playing engagement with v the needle of the reproducer. Swingable about or control theelevation to which the selectormember is moved. When the preselected elevation is reached, in each instance, the'selector member is swung about its pivot to engage and swing the corresponding selected record-carrier to a position over the turntable, whereupon the turntable is raised to pick the selected record from its carrier and present it to playing position in contact with the reproducer-needle. v

In the present invention there is embodied a bodily-shiftable stack of records so as to selectively play the records on one side or the .other, the stack remaining in a given position or being automatically reversed as determined by whether the selections preselected for play are on one side orthe other of the record-disks.

By way of example, my invention has been shown in connection with a phonograph of the kind above referred to, l5 indicating the platform or supporting frame of the phonograph chassis, i6 the vertically reciprocable turntable, ll the reproducer or tone arm carrying the usual record-engaging needle, and iii a plurality of pivoted record-carriers normally disposed in stack-like fashion at one side of the turntable and adapted to beselectiveiy swung horizontally to a position over the turntable to play the record selected and to be returned to the stack after playing.

These carriers are pivoted in superposed relation on an upright post l3 disposed at one end of an oscillatory or reversible record-carrier frame 20 supported or swiveled at its diametrically opposite sides on horizontal trunnions 2|, 22 in corresponding brackets 23, 24, respectively. The carriers are preferably ring-shaped, as shown, and therecords 26 are supported at their marginal edges in corresponding upper or lower seats 26 formed therein, the arrangement of the carriers being such that the lower seat of one carrier is alined with and in opposing or communicating relation with the upper seat of a juxtaposed carrier, whereby, upon reversal of the carrier-frame from one position to another, the records resting in the upper seats of the carriers are reversed,

' side for side, and deposited by gravity into the may be detachably connected-to the records in by support the records at their center and eliminate distortion or warpage thereof. These plates any suitable manner, as by a threaded connection wherein one of the plates is provided. with a threaded stem 26 engaging the record-hole and thecompanionplatehssathreadedopeningll toreeeivesa'idstemtoth'erebyeilectuallyclamp bothplatestotheopposlteiaoesoftherecord. 'lheselectivemovementofthecarrierstoand iromapositionovertheturntableliiseiiected by a vertically and horizontally movable selector bar 30 mounted on a yoke 3| free to slide axially and turn about a depending guide post 32 and provided at its upper end with a coupling element 33 adapted to engage a notch 34 or the like in the hubs of the respective carriers, whereby to selectively swing them into and out of the carrierframe 20. The vertical adjustment of the selector bar to an elevation in couplingengagement with the carrier I8 containing a given record desired for play is selectively controlled by a cam 35 mounted on a selector shaft 36 and a lever 31 actuated by the cam and connected to the selector bar yoke 31. Theswinging of this selector bar to in turn move the carriers to a position over the turntable is effected by a cam 38 mounted on a cam shaft 39 and a lever 40 in bearing contact with the cam and connected by a link 4| with the selector bar, all in a manner similar to that disclosed in the Wilcox patent. Selector rods or buttons 42, corresponding in number to the recordselections, that is, two for each record, are provided for selecting the records desired for play and these buttons, in conjunction with a stop arm 42 on the selector shaft 36, govern the rotation of the latter to in turn govern the vertical adjustment of the selector bar 30. Motion is transmitted to the shafts 36, 39 and the turntable by an electric motor 43, all as fully set forth in said Wilcox patent.

In the present invention the selector buttons 42 are arranged in an annular row with, say, the odd-numbered buttons representing the selections on one side of the records and the evennumbered buttons representing the selections on the opposite sides of the records. so that when' certain selections have been chosen by the push buttons, an actuating means will be rendered operative or inoperative to effect the reversal or non-reversal of the carrier-frame 20. While any suitable means may be employed for reversing the carrier-frame, I provide a vertically-reciprocating rack bar 44 suitably guided on the chassis and meshing with a gear 46 applied to the inner trunnion 2i of suchframe. Motion may be selectively transmitted to this rack bar in one direction, say, upwardly, by a cam 46 mounted on .the cam shaft 39 and a cooperating lever 41 having a laterally displaceable coupling or clutching head 46 at'its free end for engagement with a roller 43 or the like applied to the lower end of the rackbar. initial position may be efiected by a spring 60 applied-to the lower end of the rack bar. The displacement of the coupling head 46 on the rack bar actuating lever is selectively governed from the push buttons and cooperating selector shaft 36, the latter having a disk or wheel 5| thereon having on its face an annular row of protuberances 62 and intervening low spots or depressions 63, and corresponding, respectively, to the odd-numbered and even-numbered push buttons. These protuberances and depressions act to control a shiftable lever 64 pivoted intermediate its ends at 66 and having one end in operative engagement with the face of the wheel 6| and its other end in abutting engagement with the coupling head 48 which is pivoted at 66 to .the lever 41 to rock transversely'thereof into or out of operative engagement with the rack bar roller 43. When this lever 64, by reason of a preselected positionof Restoration of the carrier-frame to its the wheel ll determined by a selected push but- 1 ton, registers with a protuberance on that wheel, it acts to displace and hold the coupling head 43 ontoftheplane oftherack-bar roller 40, sothat when thelever 41 is actuated, it will merely swing idly past the roller without transmitting motion to the rack bar and hence noreversal of the carrier-frame will take place. However, when such lever 54 registers with a depression on the wheel, the coupling head will be shifted into the plane of the roller 49 and motion transmitted to the rack bar to in turn rock the carrier-frame and reverse its position to expose the selection desired on a given record face up preparatory to swinging that carrier with its record to a position over the turntable. A spring 51 connected to the displaceable coupling head tends constantly to urge the latter into the plane of the rack bar roller.

During the oscillating movement of the carrier frame 20, the selector bar 3'0 is free to be displaced thereby into and ut of its normal upright or operating-position and for this purpose is pivoted at its lower end at 58 to the yoke 3| while 'a spring 62 applied thereto constantly urges it to seek a normal operative position for coupling engagement with the carriers l8.

When the carrier-frame 20 is swiveled from its normal position for playing, say, the top sides of the records, to its reversed position for playing the bottom or opposite sides of the records, it swings in a clockwise direction viewing Figure 4, due to the actuating upstroke of the rack bar 44, and is releasably latched in such reversed position by said dog and being adapted for tripping engage-' ment at its opposite end with a pin 66 applied to the lever 40 which effects the swinging of the selector bar 30 to. in turn swing the carriers into and out of the swiveling stack-frame. This releasing action takes place at the end of the return stroke of the lever 40 in returning the carrier of the played record back tothe stack, so the moment the dog 63 is released, the carrier-frame oscillates in a counter-clockwise direction under the tension of the spring 50.to its normal position and isarrested and held in that position by companion stops 61, 68 applied to theframe 20 and bracket 23, respectively.

The free end of the carrier-frame 20 diametrically opposite the carrier-pivot It! includes a carrier-sustaining member or block 69 having transverse ways or notches 10 therein with which the adjoining. edges of the' carriers engage when in position within the frame, as shown in Figures 3 and 5. During the swiveling movements of the frame, -it is necessary to hold the carriers l8 against swinging outwardly therefrom, and for this purpose I provide releasable latch plates 'Il having escapement notches 12 to opposite sides of the block 69, said'notches registering with the block-notches 10 in the normal and reversed positions of the carrler-frame to permit the selected withdrawal of thecarriers, and the latch-plate being shiftable to. positions out of register 'with thoseblock-notches during the swiveling of the frame. A spring 13 is associated with each latchplate for urging it in a direction against a stop 14 wherein the escapement notches 12 are out of register with those of the block 69. Movement of each latch-plate against the resistance of its the latch-plates functions when the frame is' swung in a clockwise direction to latch the recordcarriers against displacement and the companion latch plate functions when the frame is swung in a counter-clockwise direction.
