The phonograph apparatus illustrative of. the inventionis provided, as shown in Figures l and 2, with a suitable cabinet generally indicated by the reference character A, which 'may have a sound opening or grille B, a sight opening or window C, a selector control means aperture D, and a coin or other control means aperture E. As illustrated, the cabinet A may be divided into upper and lower compartments F and G respectively by a cabinet partition H. l

In the lower compartment a suitable speaker or sound converter I may be mounted adjacent the grille B and electrically connected with an amplifier J also in the lower compartment; The upper compartment is adapted to receive a chassis or frame, generally denoted by the reference character K, serving as mounting means for the.

phonograph apparatus'other than the speaker I and the amplier J which are operatively associated therewith. f

That chassis K comprises a supporting panel L, sometimes referred to in the art as a motor board, removably supported in the cabinet by any suitable means, and a substructure or frame suspended as at M from the supporting panel L and having a generally rectangular member N adjacent the panel L, spaced side members O and P depending from opposite sides of. the rectangular member N, and a bottom member Q connecting the lower ends of the side members O and P and thereby spaced from the rectangular member N. f

Generally speaking, the chassis 'K carries thereon, opposite or .in such position as to be visible through the sight opening C, record reproducing or playing means R, record storage or carrying means S including bearing or supporting means U for the record carrying means S, a turntable T, record selecting means V, and record delivery means W. The driving, controiling, and timing means and connections for and with the foregoing apparatus, are carried bythe chassis K below the supporting panel L.

It will be understood4 that the operation of a control member X (accessible through the aperture E), whether or not operating means Y (accessible through the aperture D) for the selector control means -is operated, will cause the record delivery means,A W to operate, whereby a record from the storage means S will be supdisc 39 axially of the spindle.

Z, and those'electrical impulses, after amplification Jby the amplifier J, are converted into sound by the speaker I.

The turntable T is of the reciprocable type,

and as indicated inFigure 13 is reciprocab'le be' `tween a non-playing position shown in broken..

lines and a playing position shown insfull lines, for cooperation with the record delivery means W to remove records from the record storage means S to playing position, and after the playing thereoi` to return the played record ;to the record storage means S. vIn other words, the reciprocable turntable and the record delivery means together provide record changing means for the phonograph of the invention.

That reciprocable turntable T is .carried on a shaft 3l which is slidably iournaled in a motor Aframe 32 of a turntable rotating motor that is slidaloly coupled, as schematically indicated at 34,. thereto :for rotating the shaft to rotate the turntable. The shaft 3l has an enlargement or head 35 at its lower end by means oi which the shaft may be reciprocated to move the turntable between a playing position with respect to the playing means R and the non-playing posi` tion illustrated in broken lines in Figure 13.

As will be understood, the playing means R includes -a needle 36. In playing a record the needle 35 engages it near its periphery and iol.

lows the sound track on the record toward the center, thus swinging the tone or playing arm R from a starting position to position over- 'hanging a central portion oi the record. Novel means are provided forautomatically returning the tone arm R' t0 its starting position as it cornpletes the playing of each record supplied thereto by the record delivery means W and the reciprocable turntable T. l

That novel tone arm return means comprises a -rotatable' spindle 31 journaled as at 38 in the chassis K and carrying at its upper end the tone or playing arm R. and at its lower end, loosely mounted thereon', a disc 39 having an annular serrated portion 4l on its upper surface, a notch or slot 42 in its peripheral wall 43, a radially' outwardly extending arm 44, and a depending lug or stud 45. That disc is held on the 'lower end of the spindle 31 by a retaining ring 46 secured on the end of the spindle to rotate therewith by any suitable securing means 41, and having a projection 48 extending radially therefrom suii'iciently to engage the depending stud 45 for a purpose appearing more fully hereinafter. l

p A substantially T-shaped driving member 49 with its vertical arm l5l embracing the spindle 31 above the disc 39 and secured to the spindle as shown in Figure 17, cooperates with the retaining ring 46 for preventing movement of the The T-shaped member 49 has oppositely extending arms 52 which overhang diametrically opposite portions of the annular serrated portion 4|. Loosely pivoted at the end of each arm 52 is a bell crank lever 53 withaI depending arm 54 having a knife edge 55, and with a laterally -projecting arm 56 spindle 31 in one direction (the direction caused by the tone arm swinging from a starting position toward the center of the record or turntable), 4the knife edges 55 have driving engagement with the serrated vportion 4| of the disc 39, but when the arms 52 swing ln the 'other direction (the direction caused bythe tone arm-returning to its starting position), the knife edges have sliding engagement with the serrated portion 4|.

The tone arm is returned to its starting position by aslidable arm 51 slidably secured as at 58 to the under side of the chassis member N anclyieldably held in retracted position vby a spring 59. That slidable arm carries an adjustable member" 6| engageable with the outwardly extending arm 44 for rotating the disc 39 in sueh a direction that the depending stud 45 drivingly engagesthe projection 48 and rotates it, and hence the retaining ring 46 which drives the tone 4arm toward its starting position. The direction of that rotation, it will be remembered, is such that there is driving-engagement between the knife edges 55 and the serrated portion 4| of the disc 39. For 'effecting such movement an operative lever 62 is pivoted as at '63 to the chassis K, and has one' end connected as at 64 to the slidable arm 51 and an end 65 by means 4of which the mechanism justl described may be operated.

Thus, as the tone arm swings under the action of the-record toward the central portion thereof, the projection 48 swinging with 'the tone arm spindle drivingly engages the depending stud 45, and the knife. edges 55 drivingly engage the serrated portion 4|, thereby causing the disc 39 and the T.shaped driving member 49 to rotate together with the in-swinging or playing tone arm.- If the record is of the type which terminates'wth a circular groove, the driving en gagement\ just described rotates the disc yuntil the needle 36 reaches the circular groove. If

the record terminates with the familiar eccentric groove, the tone arm is caused to oscillate. The oscillations ofthe tone arm are transmitted by the spindle 31 to the T-shaped driving member 49. Whenthe tone arm during such oscillations is moved toward the center of the record or turntable, the knife edges 55, coacting with the lserrated portion 4|, drive or rotate the disc 39, and when the tone arm is moved in the opposite direction the knife edges slide over the serrated portion 4|, the net result being rotation of the disc 39 intermittently a distance depend- `ing upon the throw of the eccentric finishing groove of the record. y

The v record storage means S is adapted to receive a plurality of phonograph lrecords which are individually supported and latched therein and which may be removed therefrom one at a time for playing. vAs illustrated, the record storage meanscomprises a plurality of ring-shaped record bearers or trays 66, each adapted to carry a record and having a mounting arm 61 projecting outwardly from its periphery. The mounting arm 61 has intermediate its ends an aperture 68 and at the outer end thereof an operating finger 69 and a latching slot 1|.

The apertures 68 permit loosely pivoting the trays 66 in aligned relationship or in stack on a rotatable spindle 12 secured to the chassis member N intermediate the ends of the spindle. The

operating fingersA 69 may be moved to swing the trays66 between positions of alignment with the Aturntable T and respectively coplanar positions in stack laterally removed from `the turntable.

To` provide supporting, bearing, and guiding surfaces for the swingable trays 66, a plurality o f bearing discs 13 having arcuate apertures 14 and peripheral shoulders or projections 15 and 16 are assembled on the spindle 12 in alternating relationship with the arms 61. The discs 13, together with a bottom disc 11, are held in assembled and spaced relationship on the spindle 12 by bolts 18 and spacers 19. f

In that manner a cylindrical bearing `hub is provided adjacent an arcuate aperture 8| in the chassis member L, and the aligned apertures 14 ofjthe several discs constitute an arcuate passage extending longitudinally of the hub. The aligned peripheral shoulders or projections 15 and 16 respectively dene the operating range of the operating fingers 69. The bottom disc 11 is of larger diameter than the discs 13 to provide an end flange for the hub assembly which 'has a portion 82 adjacent the aligned shoulders or projections 15 and a portion 83 adjacent the aligned shoulders'or projections 16, serving as selector limiting surfaces when the phonograph is operated without any selection having been made or upon the cancellation of previously made selections. 'e If desired, individual tray supporting means 84, as shown more particularly in Figures to 23, may be provided to supplement the bearing support afforded by the supporting means U. Two such supplemental supporting means may be provided to support the ring-shaped trays 66 at their peripheries diametrically opposite themounting arms 61 when the trays are in' stack and when any one of them is aligned with the y turntable, but since the supplemental tray supthe storage means S at aposition diametrically opposite the tray mounting means 61, and in the other case adjacent the turntable T at a position diametrically opposite the mounting arm 81 of any tray 66 aligned with the turntable T. Each arm 85 is provided with a plurality of transverse slots 88 so spaced and positioned that each will receivea linger or projection 89 o'n a tray 66. The slots 8.8 provide supporting surfaces 9| for the fingers 89 on spaced arms 92 which have enlargements pr beads 93 at the entrances of the slots to hold the fingers 89 therein but to permit the swinging of the individual trays 66 by the 4record delivery means W.

If desired, as shown in Figures 20 and 23, the

arm 85 adjacent the turntable T may be provided with an angularly disposed plate or strip member 94 having indicia 95 thereon opposite each slot 83 andvisible through` the sight opening C in the cabinet for indicating the selected vrecord which is aligned with the turntable.

'I'he trays 66 are releasably retained in their stack position laterally of the turntable by latching means 96vof yokelike construction, with its upper arm 91 and its lower arm 98 swiveled on one of the bolts 18 and extending therefrom to positions outwardlyV spaced from but registering with the aligned latching slots 1|, and with its connecting arm 99 extending into the passage provided in the bearing\hub by the aligned arcuate apertures 14. A spring Inl normally urges the latching means 96 towards. latching position in which the connecting arm 99 engages in the aligned latching slots 1| of the trays 66 in stack.

A latch operating stud |02 is provided on the them to the storage means, the record delivery means W comprises a swingable yoke |03 'xed on the spindle 12 to rotate therewith by means of an uper arm |04 secured as at |05 to the upper end of the spindle 12 and a lower arm |06 iixed to the lower end of the spindle 12. The arms |04 and|00 are connected" at their outer ends by a vertical yoke member |01 passing through the arcuate aperture 8| in the chassis member L and having an elongated aperture or slot |00 extending longitudinally of the yoke member |01 between the arms |04 and |06 and an elongated aperture or slot |09 extending longitudinally ofl the yoke member below the lower arm |06.

The upper arm |04 has a cam portion adjacent the spindle 12 and engageable with the operating stud |02 for releasing the record trays to permit swinging one of them to its position of alignment with the turntable. means H2 extending between the upper and lower arms |04 and |06 is swingable therewith 'in the arcuate passage provided by the aligned disc apertures 14 for engaging the operating finger 69 of any record tray While it is aligned with the turntable, and swinging that record tray to its position in stack.

The lower arm |06 has an operating portion or crank H3 for oscillating the rotatable spindle 12 and the yoke |03 rotatable therewith to cause the restoring means l |2 to swing the, record tray 66 from its position of alignment with the turn table to its position in the stack, yand for oscill/ating a selector finger or projection ||i4 on the selector V'with the vertical yoke member |01 to engage a record tray operating finger 69 between adjacent or successive discs 13 and to swing the record tray to a position of alignment with the turntable.`

That selector finger or projection ||4 forming a part of the selector V is slidable longitudinally of the yoke member |01 between the bottom disc 11 and a position above the top disc 13 (see Fig. 12). It is carried on a selector slide bar l5 slidably secured as at I6 outwardly adjacent the yoke member |01, and extends through the aperl ture |08 therein toward the cylindrical bearing hub a distance suiicient to engage any one of the tray operating ngers 69'whic-h may be at the same level therewith. The slide bar ||5 has an operating vlug ||1 near its lower end, as shown in Fig. 11, by means of which it may be raised to a position at which the projection or nger ||4 adjacent the aligned shoulders 15 will clear thev top disc 13 when the yoke |03 is vin the" full line -position shown in Fig. 5.

' As disclosed in my copending application, Serial No. 11,091, filed March 14, 1935, now United States Letters Patent #2,036,103, the slide bar I5 is held in that elevated position by means of a latch ||8 pivoted to theyoke member |01 as shown in Fig. 11. I That latch has a dogging or pawl portion |9 normally urged by a spring |2| `toward dogging engagement with a serratedr or toothed edge |22 of the slide bar.' An operating Restoring y y portion |23 of the latch H3 permits releasing it from latching engagement with the slide bar' H6.

With the slide bar thus elevated, the yoke |03 may be swung by the crank ||3 toward the aligned shoulders 16 or toward the broken line position shown in Fig. 5. When the yoke has reached a position such thatthe selector finger ||4 has passed beyond the aligned shoulders 16, the slide bar H5 may be 'released by operating the portion |23 of the latch IIB.v Upon releasing the slide bar in thatposition, it will gravitate so that the selector finger H4 is adjacent a. predetermined record tray operating finger 69 or to the limiting suriace83 of the bottom disc 41i, asl will presently be explained, the descent of the slide bar H5 being substantially silent and gradual, due to a dash pot device |24 connected thereto as at |26.

In order to predetermne or to select the position to which the slide bar H5 thus gravitates, the ront chassis member O is constructed as a dividing arm for a generally rectangular frame |26 integral with the chassis member' or dividing arm O. The frame |26 is provided at a side thereof with a plurality of vertically spaced arms or lugs |21 extending therefrom laterally toward the dividing arm O for pivotally carrying a plurality of spring-urged retaining pins |28.

Each of the pivoted pins |28 is urged axially thereof by a spring |23 to engagement in a notch |3| at the end of a selector-control arm |32 pivoted at its other endvbetween vertically spaced mounting lugs |33 projecting laterally and rearwardly from the opposite side;I of the frame |26, As disclosed in my copending application, Serial No. 11,092, filedA March 14, v1935, now United States Letters Patent #2,119,251, there are provided as many arms |32 as there are record`trays 66, and each arm is supported intermediate its ends by vertically spacedrearwardly extending lugs |34 on the dividing arm O. The selector control arms |32 are thus pivotally mounted at a level below the cylindrical tray supporting hub such that When the selector operating lug ||1 rests upon any arm |32 (Fig. 11), the selector i finger I4 will be at the same level as ione of the operating fingers 69 of the record trays 66.

Those selector control arms |32 or any one or moreof them may be individually swung in any for example, a plurality of selector buttons4 |35 `that are slidably held in individual passages |36 provided in the chassis member O at a. position registering with the selector operating aperture D in the cabinet. v

The outer end of each passage |36 has an internal shoulder |31 engageable by an external shoulder or flange |38 on the button therein to limit the movement of the button in one direction. Each button has a central bore or depression |39 notched or countersunk as at |4| to provide an internal shoulder |42 therein. The borev |39 of eachbutton is adapted to receive therein a stem |43 carrying'a spring |44 and having an operating head |45 which is engageable with one of the arms |32, the spring |44 encircling the stem be` tween the shoulder |42 andan abutment |46 on the stem adjacent the head |45. By that conf struction the buttons |35 are reciprocable in their respective passagesv |36, whereby the operating heads |45 Awill respectively engage the pivoted be automatically swung to their respective selectarms |32 and swing them about their pivots into lthe path of the operating lug ||1 as the latter gravitates with the slide bar ||5 in the manner described above.

A plurality of. selector .control arms |32 may ing positions in order that the records in the storage means S may be played successively. As illustrated, that is accomplished by a yoke-like 1'0 member |41 having an operating finger |48 connected to its upper arm |49, which in turn is pivoted as at |5| on the frame 26 and having its lower arm |52 pivotally secured to the lower part of the frame |26 so that its connecting member |53 spans the pivoted arms |32 between the lugs |21 and |34 and is engageable' with the f arms when they are in their non-selecting positions.

For automatically operating all of the arms as just described, a paw] |54 is pivoted as at |55 on the slide bar ||5 at such a position that when theslide bar gravitates until the selector nger I4 reaches the limiting portion 83 of the bottom disc 11 and swings with the record delivery means 25 W from the broken line position of Fig. 5 tothe selecting positions.

record delivery position shown in full lines in( Fig. 5, the pawl |54 engages the operating nger |48 and swings it in a direction to cause the connecting member |53to move the arms |32 to their The pawl |54 is resiliently urged toward a stop lug |56 by a spring |51 on the slide bar H5, as shown in Fig. 1l.

- Each arm |32 is provided with a cam surface |58 engageable by the operating lug l|1 when 35 it has been stopped by that particular arm in its downward movement and during the swinging of the record delivery means W, as just described, toward a record delivery position to cam the arm |32 back to its non-selecting position.

A cancellation button |59 constructed like the buttons |35, the parts of the button |59 corresponding with those of the buttons |35 respectively bearing the primed reference characters thereof, is adapted to move a cancellation yoke |6| pivoted as at |62 to the upper and lower members of the frame |26 and spanning the arms |32 at the corresponding sides thereof opposite those spanned'by the automatic multiselecting yoke |41 for moving any or all of the arms |32 from selecting to non-selecting position.

celing position.

A main dperating motor |64 is suspended, asv

A spring |63 secured at one end to the chassis member O and at its other end to'the upper arm of the pivoted .cancellation yoke resiliently and yieldably holds the yoke in its normally non-canshown at |65.' from the chassis member N and is drivingly coupled by a belt and pulley connector l |66 or other suitable drive connections with a worm |61 journaled in a chassis member |68 depending from the chassis member vN for driving"v cam means |69 -of substantially barrel-like or cylindrical conguration carried on a shaft '|1| journaled at its ends in the spaced chassis mem bers N andNQ, as shown best in Fig. 8.

That barrel-like cam means .|69 has at one'end 'thereof a worm wheel |12 driven by the worm |61, and an arcuate member |13 spaced from the 70 worm wheel |12' by a pair of helix-like upper rails |14 and |15 diverging from near the periphery of the worm wheel toward the arcuate member |13, and connecting the worm wheel with the arcuate member. Reinforcngbars or arms |16 extend 75 longitudinally of the barrel-like cam and connect lowerrails |11 and |18, extending from the worm wheel |12 in spaced and substantially parallel relationship with the rails |14 and |15 respectively to .below the arcuateY member 13, providing a cam slot or track |19 with an entrance or mouth |8|, a rise |82, a dwell |83, a fall |84, and an outlet |85. The upper surface of the worm wheel |12 is formed with an irregularly curved cam groove or track |86 and an upstanding selector release member |81, a stud or nger |88 being provided adjacent the release member |81, and a tone arm return stud or nger |89 being spaced from the stud |88 on the worm wheel and adapted/` to engage the operating lever for returning the tone arm'R to its starting position. To the lower end of thecam means |69 a disc or plate member |9| is secured, as shown in Figs. 7, 13, and 14, to rotate therewith, and is provided with a notch or slot |92 in its peripheral wall |93 and a stud or finger |94 depending from its lower face;

For operating the reciprocable turntable T and the selector V from the cam means |69, a slide member |95 is reciprocably secured to the rear` 'Ihe end of the arm |98 opposite the pivotal connection |99 is engageable by adjusting means 202 for adjustably urging the notched lug |91 to slidable engagement with the chassis member P. The slide member |95 is provided with a cam follower 293 projecting from its front face and receivable in the cam, track |19 for reciprocating theslide, member along the'rear chassis mem- `ber P.

For operating the head 35 of the turntable shaft 3|, whereby to move the turntable T to and from a' playing position, the slide member |95 is provided with a laterally projecting arm 204 which is reciprocable with the slide member and which has a portion 205 engageable under the head 35 and a bifurcated portion 206 spaced from the portion 205 lby anl upstanding arm 201 and engageable aboutthe shaft 3| above the head 35 whereby positively to drive the shaft against the turntable T inv both directions of its reciprocable movement.-

Projecting from the opposite side of the slide member |95 an arm 208, reciprocable therewith, extends slightly arcuately about but spaced from the barrel-like cam means |69, and is adapted to engage the operating lug ||1 of the selector slide bar ||5 when the swingable yoke |03 is in the position shown in`full lines in Fig. 5. Thus, as the slide member |95 is raised by the cam track |19-and itsfollower 203, the slide bar ||5 is raised to a position in which the selector linger or projection ||4 clears the upper bearing disc follower 203 rides in'the dwell |83 of the cam.

member |95, and hence the arms 204 and 208, to

' remain in their upper or raised positions. Further rotation of the barrel-like cam means |69 causes the fall |84 of the cam track |10, by its action on the follower 203, to lower the arms 204 and 208, thus lowering the turntable, thel follower 203 passes out( of the outlet |85 from the cam track |12, whereupon the irregular cam.

groove |85 on the worm wheel |12 operates a cam follower 209 on the arm or crank H2 to swing the spindle l2 in such a direction as to move the swingable yoke |03 carrying the selector finger |04 toward the broken line position shown in Fig. 5. That cam groove |06, in thus swinging the cam follower 209, moves it toward a substantially "dead center position 2|`|-of the cam groove.. -At that position a cam portion 2|2 on the lower arm |05 of the swingable yoke |03 is engaged by the stud |58 on the worm wheel |72 and is cammed in a direction to rotate thespindle l2, and with it the crank M3, until the cam fol- Ilower 209 on the crank H3 passes that dead center position 2H of the groove |05 and enters a communicating portion of the cam groove for resuming the operation of the swingable yoke |033 f by the cam groove |05.4

During that engagement between the stud |58 and the cam portion 2|2, the cam portion lll on the upper arm |04 of the swingable yoke |03 engages the latch operating stud |02 and operates the latching means 95 to release the record carriers 55. Further rotation of the cam |652 brings the swingable yoke itt/to the broken line position shown in Fig. 5, at which position the upstanding selector release member |82 on the worm wheel |22 engages the latch |23 and opcrates it to release the slide bar H5. At that time the selector nger |1113 has swung beyond the aligned shoulders or projections 'it so that the slide bar can gravitate silently until it is arrested by its operating lug 'i il engaging on the topmost selectorcontrol arm |22, which has previouslyI been moved to a selecting position by one ofthe buttons |25.

When the selector slide bar H5 is arrested in its downward movement by engagement between the operating lug iii' and a selector control arm |32 in its selecting position (see Fig. 8), the selector finger il@ is adjacent the operating finger 59 of fthe-tray 55 carrying the record corresponding tothe operated button |35. The cam groove |26 now acts on the follower 229 and through the crank H3 to reverse the direction of rotation of the spindle '|2 wherebyl to swing the yoke |03 back toward its record delivery position shown in full lines in Fig. 5. During that swinging of the yoke |03 the selector vfinger H4 engages the operating finger 69 and swings the selected tray 66 to its position of alignment with the 'turntable T, the spring |0| returning the the cam portion clears the latch operating Y stud |02 for holding the other trays 66 in. stack.

On the face of the slide member |95, opposite vthe cam follower 203, is a pair of spaced studs 2|3 and 2|4 whichpass through an elongated aperture or slot 2|5 in-the rear chassis member P and an elongated aperture or slot 2|6 in a reciprocable separator 2|1 which is held on the studs 2I3 and 214 adjacent the chassis member memberZ P by any suitable retainingmeans 2 8, and which extends upward and through an aperture 2|9 in the chassis member L betweenk the record storage means S and the turntable T. That separator 2H is arranged to reciprocate with ythe slide member by a connector 22|, preferably resilient, extending between the stud 2|3 and an anchorage 222 at the lower end of the separator 2H.

When the selected record has been moved to its position of alignment with the turntable T, as just described, further rotation of the barrel-like cam |50 causes the entrance |8| of the cam track |19 to receive the cam follower 203 on the slide member |05. During the raising of the turntable Tin the operation of the selector operating lug Il by the slide member arms 202 and 205 respectively, virtue of its connection with the slidemember |95 to a position between the storage means S and the tray 55 aligned with the turntable, whereby positively to separate the aligned tray from the storage means and to hold the aligned tray in alignment with the turntable.

If desired, as illustrated in Figs. 1, 2, and 3, the phonograph of the present invention may be controlled by coin or token operated mechanism, in which event the control means X will include a4 reciprocable coin receiver 223 which, when pushed in (Figs. l and 2) is adapted to deliver a the separator 2|`| is raised by` coin to a coin chute or slide 222 for operating a switch arm 225 pivoted as at 225 and having one end extending into the coin chute 224, its other end carrying a switch contacting surface 22? associated with a switch contact 220.

That control switch is electrically connected )in series with a suitable source of electrical energy diagrammatically indicated by the reference numeral 222, and an electromagnet 23|,

4Vby electrical conductors 232, 233,' and 23d. Thus,

235 pivoted intermediate its ends as at 235 and having at opposite ends ratchet operating teeth' 231' and 232. The pawl 235 is normally urged byv a spring 230 away from the magnet 23|. In that position the tooth 237 engages between adjacent teeth 26| of a ratchet 242 rotatably mounted as at 243 on the chassis member Q, and the tooth 238 is spaced from the tooth 237 a distance such that when the magnet is energiz'ed, the tooth 230 engages a ratchet tooth and cams or rotates the ratchet l242 slightly, Thus, when the magnet is deenergized and the spring 229 swings the 'pawl 235 from uthe magnet, the

tooth 23| engages a ratchet tooth and cams the ratchet 242 a distance sufficient to make the combined rotation of the 4ratchet by both of the teeth 237| and 238 equal the distance between adjacent or succeeding ratchet notches The ratchet 242 has a 'switch operating stud 244 depending therefrom which normally engages a switch arm 245 ofwa switch 246, mounted as shown in Fig. 14 on the chassis member Q, to hold a pair of switch contacts 241 (Fig. 3) open against the action of a resiliently urged switch 248 engaged by the switch arm 245. Thus, when a coin or token operates the switch arm. 225 to energize the magnet 23|, and the pawl tooth 231, under the action of the magnet 23|, disengages the ratchet 242, the resiliently urged switch member 248 operates the switch arm 245 to close the contacts 241 and to rotate the ratchet 242 one notch. Each subsequent coin or token operating the switch arm 225 to energize the magnet 23| before the ratchet is returned to its normal position, will result in the operation of the ratchet 242 by the pawl teeth 231 and 238 one additional notch in the same direction as produced by the resiliently urged switch member 248.

When the switch contacts 241-are thus closed, an electrical circuit is completed from a diagrammatically illustrated source 249 of electrical' energy through conductors 25|, 252, and

253, the turntable motor 33, conductors 254 and 255, the contacts 241 and conductors 256 and 251, back to the source of energy 249, thus energizing the turntable motor 33 and starting the turntable to rotate..

The closing of the switch contacts 241 also completes an electrical circuit through a switch 258 mounted on the chassis member Q adjacent the disc |9| secured to the lower end of the barrel cam |69. That switch has a switch arm 259 and switch contacts 26| which are normally held closed by thev engagement between the peripheral disc wall |93 and the switch arm 259 against the action of a resiliently urged switch member 262. The switch 258 is electrically connected to the main motor |64 by conductors 263 and.264, and that motor and switch are.connected in parallel with the turntable motor 33 by conductors 265 and 266. lThus, the motor |64 is also energized when the control device X is operated.

When the motor |64 is so energized, the record selector means 'V and the record delivery means W arevelevated as shown in Fig. 4, and are just to the left of their position shown in broken lines in Fig. 5. All of the trays 66 are in stack. The turntable is in its lower or non-playing position,

and the playing arm is at its starting position.'

The energized motor |64 rotates the barrel cam means |69 by means of the worm |31 and the worm Wheel |12, causing the cam track |66. by its actionon the cam follower 209 carried on the crank H3, to swing the record delivery ,means W to its broken line position in Fig. 5, whereupon the selector release ymember |81 on the worm wheel |12 operates the slide bar latch ||8 to cause the latch pawl H 9 to disengage the toothed edge |22 of the selector or slide bar I 5.

`When soreleased, theselector or 'slide bar |-|5 gravitates until the operating lug ||1 engages 'that selector control arm |32 or the uppermost selector control arm |32, which may have been .moved to the selecting position or positions (Figs.

descent of theselecto or slide bar ||5, to swing the tray 66 bearing the selected record to a posiltion of alignment with the turntable T.

After the tray 66'bearing the selected record reaches its position of alignment Iwith the tuntable T, the barrel cam means |69 continues rotating, causing the entrance |8| and the rise |82 of the cam track |19 to engage the cam follower 203 for raising the slide member |95. As thev slide member |95 is thus raised, the turntable reciprocating arm 204 of the slide member elevates the rotating turntable through the ringshaped'itray 66' aligned therewith to take the selected record therefrom and to present it to the playing arm R for playing. I

It will be seen that while the slide member |95 is thus raising the turntable, it is also raising both the selector or slide bar by the arm 268 engaging the operating lug ||1 and the separator 2|1 connected to the slide member by the spring 22|. The rotating turntable, the selector or slide bar ||5, and the separator 2|1,

are elevated in that manner until the turntablev .tion outside of the storage means S. When the rotating turntable reaches its playing position, the disc |9| secured at the lower end of the cam means |69 to rotate therewith has rotated to a position at which its notch |92 is in registration with the switch arm 259 of the switch 258, which is then opened by the resiliently urged switch member 262 urging the switch arm into the notch |92. Thus, thev circuit of the main motor |64 is interrupted or opened and the motor is stopped, stopping the rotation of the barrel cam means E69 while the turntable T is in. its raised or playing position. It will be observed, however, that the circuit including the turntable motor 33 and the switch 246 remains closed so that the motor 33 continues rotating turntable T. At that position the cam follower 203 rests in the dwell i83.of the cam track |19 to support the turntable arm 204 in its raised position, thereby providing supporting means for the rotating turntable while it is in its playing position.

` In the playing position of the turntable, the needle 36 engages the sound track on the record rotating with the turntable to play the record. The needle following the record sound track causes the tone arm R to swing toward the center of the record. When the needle 36 reaches the end of the sound track, the tone arm has swung toward the center of the record and has vcontact member'283 secured on an insulator 284 supported by a switch 268 secured as at 269 (Fig. 16) to the chassis member L adjacent the lower end of the spindle 31 (Fig. 6). That contact member 283 is electrically connected by a conductor 285 to the pick-up Z, and when it contacts with the depending stud 45 which is grounded to the chassis K, the pick-up Z is short-circuited so that the electrical impulses therefrom are not delivered to the amplier J for amplication and subsequent conversion into sound by the speaker'I. It will be seen that this muting of the pick-up Z will effectively pre-vent amplifier h when the needle'36 reaches the end of the recorded sound on the record.

At the end of the sound track, whetherl it terminates in a circular groove or an eccentric groove, as explained above, the knife edges 55 move or drive the disc 39 on the tone arm spindle 31 to such a position that the notch 42 is in gaging the switch arm 261. When the notch 42 43 of` the disc 39 registers with the switch army 261,v the resiliently urged switch member 212 urges the switch arm into the notch, thereby closing the switch contacts 21|. i

The closing of the contacts 21| closes an electrical circuit from the source 269 of electrical inthe peripheral wall energy to the main motor |641 by way of the conductors 25|, 252, and 265, through the motor 164 to the switch 266 by way of the conductor 264 and a conductor 213 (Fig. 3), through the,

switch contacts 21| to a ,conductor 211i, and therefrom back to the energy source 269 by way of the conductors 256 and 251. In that manner, upon the completion of the playing of va record, the main motor E64 is restarted for resuming the driving of the' barrel cam means |69, thus causing the peripheral wall |9111 of ythe disc |93 at the lower end of the cam means |69 to close the switch contacts 261 of the switch `When the cam means 169 is restarted, the dwell |83 of the cam track |19 leads the cam follower 263 in the fall 184, which causes the lowering of the slide member and hence the separator 211, the turntable reciprocating arm 264 and theselector operating arm 2118, the selector or slide bar 11S-being retained in its elevatedV position (Figs. 4, 5, and 12) by the latch pawl i119 engaging the toothed edge |22. w In moving toward its lower position, the turntable reciprocating arm 2M brings its bifurcated portion 20d against the operating enlargement 35 at the lower end of the turntable shaft 3| to lower the turntable. The turntable is thus moved away from lits playingposition downwardly toward a loweror non-,playing position shown in broken lines in Fig. 13. The turntable in its downward movement passes through the held in alignment there- 211, and leaves the played ring-shaped tray 66 with by the separator record inthe tray. v

During the. descent or' the turntable T and the separaton2l1, the tone arm return stud |89 on the lworm wheel |12 engages vthe operating end 66 ofthe lever 62 and swings the lever to move theslidable arm 61 against the action of the spring 59 in a direction to return Vthe tone arm to its startingfposition, thus rotating the disc c3&1 sothat the switch arm261 no longer engages in the notch 42 but is engaged by the peripheral wall 43 of the disc to hold the switch contacts 217i open. and so that the depending stud 4,5 disengages the contact. member-283 to remove the short-circuit from the pick-up Z. Opening the switch contacts 21| as just described does not stop the main motor |64 because the'peripheral wall |93 of the disc |9| rotating with the cam means |69, has, as already .thewitch 25s.

vAfter the turntable T has'deposited the played record in the tray 66in the pathA 0f the turntable, the irregular cam track |86 on the worm wheel |12 swings the record delivery means W andsthe selector means V carried thereby from thef record delivery position shown in full lines Ytoward the broken line position shown in Fig. 5.

4record delivery means W and the selector means means available for delivery notches from its normal position,

During that movement of the record delivery means and selector means, the restoring means Y H2 engages the operating finger 69 of the tray 66 bearing Vthe played record, and swings it with the played record back toward the stack or stor- 5 age means S. .s

Just before the record delivery means W reaches its broken line position of Fig. 5, the stud |88 adjacent the selector release member |81 on the worm wheel |12 engages the cam portion 212 on the lower arm |66 of the record delivery means, and cams the rotatable spindle 12 and the operating crank H3 until the fdead center portion 2 Il of the irregularly curved cam track |36 leadsthe cam follower 269 into a driving portion of the cam track |86, whereby the driving portion of the cam track |86 acting on the cam follower 229, and the stud |36 acting on the cam portion 212, cooperate to swing the V to the broken line position of Fig. 5.l Toward the end of the swinging movement of the record delivery means as just described, the cam portion lil on the arm |04 engages the latch operating stud i112 and operates the tray latching 96 to unlatch the trays 66 in the storage means S, whereby any .one of them Vwill be l to the path of the turntable T by the record'delivery means W.

Just as the record swinging means W reaches the broken line position shown in Fig. 5, the depending stud on the disc |91 at the lower end of the cam means |69 engages a cam portion 215 on a reciprocable arm 216, slidably mounted as at 211 on the chassis member Q, and urges the reciprocablel arm 216 in a direction to energize a spring 218 which returns the reciprocable arm to its normalposition after the stud |911 is rotated with the disc |91 sufficiently to disengage the cam portion 215. During that return movement of the reciprocable'arm 216, a pawl ortooth 219 on the arm engages the ratchet 2652 and rotates it in a direction opposite to that caused by the resiliently urged switch member' 248 and the electromagnet 23| suiiciently to return the ratchet stud 2112 to its engagement with the switch arm 245 if the control means X has been operated only once or to play only one record, thus opening the switch 2&6 and disconnecting or opening the circuit including the parallel connected motors 33 and it. Ii, however, the .control means X has been successively `operated to call for the playing or" more than one record, so that the resiliently urged switch member 248 and the together rotated the ratchet 242 a pluralityy of the return 242 by the pawl or tooth playing of rotation of the ratchet 219 will be. intermittent after the each record until all of the records called for by 61 th'e control means X have been played, whereupon the pawl or tooth 219 engages the ratchet 242 after the playing of the last of said records and rotates it sufficiently to return the ratchet stud 244 to its engagement with the switch arm 6 245, thereby opening the switch 246 and disconnecting or openingthe circuit including the parallel connected motors 33 and |64.

If the control means X is now operated, the

turntablevin its llower position (see broken linel 7 position of Fig. V13) will again begin to rotate as describedV above, and the motor |64 will resume the rotation of the barrel cam means |69, causing the selector release member |81 on the worm wheel |12 to engage the operating portion |23 of 7 electromagnet `231` have 5g 2,159,883 `the selector'or slide bar latch 8 and to cam it Imay havebeen moved to the selecting position by operation of one or more of the buttons |35 or until the selector finger |I4 engages the limiting portion 83 of the bottom disc 11. a

When the operating lug is arrested by/ a selector control arm |32, the selectonlnger is adj.' :ent the' operatinglnger 69 of a tray 66 bea ing the record corresponding to the operated selector control arm |32 or its operating button |35, so that when the record delivery means W is swung in a record delivering direction, that selected tray 66 Will be swung to theposition of alignment over the turntable.

'I'he foregoing cycle may be repeated, and lthe next lower selector control arm |32 in the selecting position (whether or not it be the control arm |32 next adjacent the one previously operated) will serve to limit the selecting position of the selector finger ||4 until all of the selected records have been played unless meanwhile the selection or selections have been cancelled by operation oi the cancellation button |59.

If the control means X is operated Without any selection having been made, and no selection is madelbeforethe selector or slide-bar ||5 reaches its lower position (i. e., where the selector finger H4 engages the limiting portion 83 of the bottom disc Tl), the vpaWl |54 at that level of the bar H5, when the bar is swung -in a record delivering direction, will engage 'the operating finger |48 on the multiselecting yoke-like member |41 and will causeall or a plurality of the selector control arms |32 to be moved to their selecting positions.' During that movement of the record delivering means W, the recordselecting finger ||4 engages an operating nger 28|, which as .shown in Fig. 19 -is connected by a pin 282 to the operating iinger 69 next above, which is the operating linger for and integral with the last or lowermost tray 66 lin the storage means S. Thus, when no selection is made, on operation of the control means 'X the novel phonograph automatically selects a record and adjusts itself to play av plurality.` of records in seriatim.

It Will be seen from the foregoing that a coin or token, or a plurality of coins or tokens successively, may be inserted in the coin receiver 223 and the control means X operated before or after the selector V is operated by the buttons |35 to select thenumber of records equaling. the number of coinsv or tokens used or the number of times the control means X ris operated. The novel phonograph of the-present invention then proceeds automatically to play the selected record or records one at a; time, and ifmore than one record has been selected to change the records upon completion of each record until all of the selected records have been played.

The multi-selecting yoke-like member cooperates with the selector V not only to assure the selection and playing of one record when the control means X is .operated once Without any selection being made, but also to adjust the selector control arms |32lso that a plurality of records may next be automatically selected for playing in seriatim if thecontrol means X is subsequently operated before the cancellation button is operated and without any further manual selections being made.

An important feature of the present invention is the various constructional arrangements such as those just summarized above for rendering the phonograph fool-proof and to assure its operation to reproduce a record for every operation of the control means X.
