To all 'whom it may concern:

Be it known that I, HARRY A. SMITH, a

citizen ofthe United States, residing at Columbus, Sta e of Ohio, have invented newand useful Improvements in Attachments for Phonographs, of which the following is f a specification. V-

This invention relates to phonographs, the object of the invention being to provide -mechanism whereby a plurality of records may be advanced to and movedaway from the playing or reproducing position and successfully operated in connection With the reproducer, the mechanism being entirelyl automatic and motion being imparted to the various elements of the mechanism from a single source Aof power which, inthe preferred embodiment of -the invention, consists of a spring motor contained Within the housing creasing of the apparatus and forming a part of the mechanism as a whole, the power generated by such motor being utilized to intermittently advance the records to and from the reproducing position, and also to clutch and release the records successively and alsol to actuate the repro-` ducer 'back and forth during its operative or the View beingitaken looking toward the ends of the cylindrical records. Fig. 2 is a vertical section Italien at right.. angles to Fig. l. Fig. 3 is a plan view of the record reproducing portion of the apparatus.

The machine comprises a boX or casing A in Which a portion of the mechanism is contained and upon Which the remainder of the mechanism is mounted, said casing bei ing shown as comprising atop .1 and bottom 2 and sides and ends Mounted in suitable hangers 4 connected to the 'underside ofthetop l are two sets of sprocket Wheel shafts fand 6 each of which carries a pair of sprocket Wheels 7 and 8 around which run parallel chains or l record carriers 9, said chains being provided at opposite points and at suitable tervals .with varcuate holders 10 upon which the cylindrical records 11 a're mounted as shown in Figs. 1, 2 and 3. As shown in F ig.

1 the chains togetherwith the records carried thereby travel in a rectangular path Within aguard 12, the ends of which eX- tend upward through openings in the top ofthe casing as shown, .which casing is also provided With apertures in the top thereof.

through which the records llpass during the` movement of the carrying chains.

The mechanism for actuating the chains and imparting intermittent movement thereto and to the records carried thereby comprises an initial spring operated arbor 13 to Which is connected a suitablepovverspring- 14. one end of which is connected to a part of the frame as shown at 15. The Winding mechanism comprises pawl and ratchet members 16 and 17 respectively for holding the shaft after the spring is wound thereon, and said arbor is squared as shown at 18 to receive a suitable Winding vkey like the key of any ordinary clock mechanism. On the saine arbor 13 there is mounted a spur gear Wheel 19 which meshes with .a pinion 20 on a counter-shaft 21 on Which is another large spur gear Wheel 2 2 which meshes with a pinion 23 on another counter-shaft 24 having also fast thereon another Vspur gear Wheel 25. The wheel 25 meshes with a spur gear Wheel 26 fast on a--cam shaft 27, all of said shafts being mounted irrsitable bearings Within .the casing A.

Fast on the cam shaft 27 is a cam 28 having an abrupt radial shoulder 29 as shown in Fig. 1 While coperating with said cam 1s one arm 30 of a cam lever, which arm 30 is preferably fprovided with a roller 31 at :theA

end thereo whichy operates against the peripheral face 32 of t e cam 28.

The other arm 33 of the cam lever has'pivotally coni nected thereto a reciprocatory bar 34 to the opposite end of which is connected a contractile spring 35 the opposite end of .which is connected at '36 to a post 37 extending downward fromthe top 1 'of the casing.y I

The bar 34Cv carries a pawl13`8whch engages the teeth of a ratchet wheel 39 which is fast i on a centrallyjarranged chain actuating shaft/10, said shaft being provided with. op-

positely arranged sprocket wheels 41 Whichl i 'engage at their upper sides with the sprocket chains 9 hereinabove referred to. Bymeans of the mechanism above described', 1t 'v'vill A' l The reproducer 42 is carried by a pivoted i beiob'served that in each complete'revolution' of the wheel'26, an intermittent throw l or movement is imparted to` the shaft 40 and the sprocket wheels 41 and consequently to the chains 9. In this way, the recordsare moved forward with a step-by-step motion, the records being carried successively to the point of reproduction and then successively v moved onward beyond said point. lne po- 10 sitioir or point of reproduction -is shown best in Fig.A 1- in which 42 designates the reproducer beneath which one Aof the records lis located while in the reproducing position.v

arm 43 whichis fulcrumed on a rod 44 supl ported by a frame 45 extending from thetop 1 ofthe casing upward as shown in` l, The reproducing arm 43 is provided with. a

- lever extension 46 which extends under a 35 screw 47 andis also provided .withanothercomparatively quick return of the repro-f` ducer and 'it will also be observed thatl the lever 46 is provided with a nutv segment 54 whichengages the under side of the feed nut segment 55v which engages the upper screw is fed lengthwise of the revolving recments thereof may be thrown into engagement with their'respective screwsat a time. When the reproducer 42 is moved downward to its' operative position, the nut segment 54 is raised into threaded engagement with the screw 47. and as the latter revolves the feed ord. `When the reproducer 42 is elevated out of contact with the record, the nut segi vidual record ment A.54 ismoved downward out of operative engagement with the' feed screw 47 while the nut segment 55 is moved down; wad-y into'. the operative"relationI to the return screw-48, the latter operating to return' the' reproducer 42 quickly to. its initial lor-v clutches being'of a'. size adapting them to enterthe op osite lendsof the hollow cylindrical recor as best illustrated. in Figs. 24

"aiid 3,'the driving cone56 being mounted o n a bracket arm extending 5 6 designating the The, cones'5'6. and -57.a11e.in` thenature of friction" the shaft 53 which is provided. with a pulother pulley 60 mounted faston shaft 6l .on which isalso Vfast a spur a spur gear wheel 62 which is driven y the spur gear vwheel 19 above described thus providing for imparting rotary mot-ion to the record. The tension cone Aor clutch member 57 1s ment 'of the records by means of an expansionspring -63 which is coiled around the shaft or spindle 64'on which the cone 57 is mounted, said spring" beinginterposed between the hub 65 of the cone and the bearing 66' in which the outer end of said spin-I dle 64 is journaled. The outer periphery of the cone 57 is grooved to receive a band 68 which tits loosely therein and is engaged by the arms of a shipping fork 68 which is Vfulcrumed at 69 on the casing, said fork being provided with a lever arm or extension -70 to'which is connected one end of a link 71" the opposite vend of which is connected to one arm of a clutch lever 72 fulcrumed intermediate its ends at 73 on a bracket hanger lextending downward from the top of the casing as clearly shown in Fig.- 2. At the side opposite the lever 72 there is arranged another lever 74 whichisl connectedl by a link 75-with a record throw-off lever 7 6 which is fulcrumed-intermediate its ends at 77 on the top of the casing, the upper end of said lever being ada ted to strike against the adjacent end of e record and move said record out of engagement with the driving cone 5.6. .The levers 72 and 74 are p connected by a rod 78 whereby both of said side) of the return screw 48. The lever 46 -is l v-soiientthat one side only of the nut Aseg- 40.

evers are simultaneously operated. The rod 7 8' is shifted by means of a cam lever 7 9 which is fulcrumed intermediateits ends by means of a pivot or.bolt 80 connected with down from the top of the casing. One end of said cam lever carries a roller 81 which works a ainst a lateral cam face 82 on the cam4 28 a ove referred to, said cambeing provided with a peripheral cam face 32'and a lateral ca i face 82. The lever 79 is actedupon by the .cam face- 82, which operatesv to shift the connecting vrod len 'hwifsel and thereby simultaneously'rock t e levers 72 and 74, one of said levers'as previously stated, controlling the tension cone orclutch 57 while the other lever controls the device bywhich the record is moved'out .of engagement with the driving cone 56;-

The levers 72 and 74 are mountedl on rock y shafts 73 and 83 and said shafts are provided with short crank arms 84 -and 85 hich connect with a .three-sided lifting frame com rising the two-sided bars 86 and the top horizontally connecting bar 87 which vvforms a guide rail -upon which 'the free end ofthegreproducer bar 43 travels, said arm being. greeted lor notched as shownI at 88 .to

.ley58 receiving adriving belt i9 from anpressed yieldingly toward the path of moveietf t said rail as shown in Fig. -.1 when the reproducerlis in operative contact with theunderlying record. 89 designates a retract# ing spring which operates to hold the roller 81 in engagement with the lateral face 82 of the cam, said spring havin one end connected to the cam lever 79 an the oppositeend connected to the post 37.

After winding up the spring lland'setvting the mechanism in motion, the power of said spring is utilized to drive the main gear.

l 26 and thereby impart motion to thecam28 which in. turn operates the bar 34Cy and pawl 38 to impart intermittent rotary movement to the sprocket chains 9 which carry the records. When a record reaches the reproducing position, the power of the-spring 14 is shifted to the mechanism for clutching the record which is then engaged by the cone above referred to and elevated slightly olf. theholders after which it is taken. up and .driven by the cone 5 6 to whichmoti'on 1s imparted by the main spring 14,-. The power of the spring is also-utilized to 'drive'fthe feed and return screws 4 7 and 48 withthe'leiect that the repro'ducer 42 is moved back and forth across the peripher ofthe cylindrical' record in a manner simi ar to phonographs now in common use. Thus the entire mech' yanism of the machine hereinabove described is automatic, requiring no attention on the part of the operator after primarily wind- -rng the spring 14, the machine operating to ord, an endless series of records, means for imparting intermittent movement to said ,series of records operating to successively arrest the movement of the records in reproducing position, a reproducer feed screw, a return screw, and a lever forming an extension 'of the reprodueer arm, and being :tulorumed between the reproducer and said screws, said lever extending to one side of the feed' screw and to the opposite side of the return screw and being provided with nut screw one at a time.`
