To all whom it may concern.' 1

lBe it known that l, SIGMUND SGHLESINGER, a citizen of the United States, and resident of New York city, borough of Manhattan, in the county of New York and State of New lork, have 'invented certain new and useful Improvements in r1alking Machines, of

- ment of the sound arm from the mid-portion of the music record to one side thereof, as to a position beyond the Astartlng point of the needle over the record, with one movement of said handle for winding the spring,

and to return the arm to an approximate starting position of the needle on the record upon the return movement of said handle; another object of my invention is to cause the automatic placing of the needle upon the music record when the plate or disk carrying the record begins to rotate; a further object being to automatically control the brake for the spring motor according to the to-and-fro movement of said handle to automatically releasethe brake when the sound arm has been brought to the starting pcsition. l

Other features of my invention will be lmore fully hereinafter set forth and then pointed out in the claims.

The numeral 1 indicates a casing of a talking machine of any suitable construction having a cover '2 hinged thereto at 3 in any well known manner. a indicates the rotative dlsk or plate having felt-like material 5 to support the music record or disk 6 irl any well known manner. At .7 is a plate carried upon shelf or top 8 of .casing 1, which plate pivotally carries the sound arm 9 in any suitable manner, In the example illustrated the sound arm is jointed at 10 to the tubular sound conducting member 11.,

journalled upon plate 7, whereby the sound `arm may have vertical and lateral movementsxin a well known manner. Since the foregoing parts are generally of any well known type they need not be further described, and the details thereof may be varied while (zo-operative with my improvements hereinafter described.

motor by a to-and-'fro movement of a handle or crank arm 24 which simultaneously operates to raise and lower the cover 2. For such purpose handle 24 is secured upon a transverse shaft 25 journalled in the casing and provided with an internal rack segment 26 and an external rack segment 27. The' rack 26 is in mesh with a gear 28 loose on shaft 14 and provided Awith one or more springacting dogs 29 co-operative with a ratchet 30 secured on shaft 14 for rotating said shaft to the right where the handle 24 is rotated to the right (Figs. 4 and 5). Rack. 27 is in mesh with a gear 31 loose on shaft 14 and carrying one or more spring-acting dogs 32 cofoperative with a ratchet 33 secured on shaft 14 and havin its teeth extending vreversely to the teeth o ratchet 28, whereby upon the reverse movement of handle 24 and rack 27 (to the left in Fig. 5) the spring of the motor will be additionally wound and at the same time the cover 2 will be closed. The arrangement is such that movement of racks 26 and 27 once forward and back will suffice to wind the spring of.- the motor enough to operate the music recordto render any musical composition thereon. Shaft 25 is shown provided with a crank arm 34 pivotally connected with a link 35 pivoted to cover 2 at 36 and shown operative a he arrangement is such that when handle 24 is rotated "frm the lower dotted position (Fig. 4) upwardly to the right to partly wind the motor sprin the cover 2 will be raised by arm 34 and ink 35, and when the handle is moved reversely to further wind the motor spring the cover will be lowered. The cover can be raised and lowered by direct operation of the handto cause link 35 and arm 34 to rotate shaft 25 to cause simultaneous winding of the motor spring without requiring handle 24. The arm 34 and link 35 may be located outside of the casing instead of within it if preferred.

I provide means to swing the sound arm 9 vfron-1 the position over t-he record 6, where the music stopped playing, when shaft 25 is firstrotated to wind the motor spring with-the' raising of cover 2 and to move the sound arm reversely approximately to the y start-ing position of the needle on the record when said shaftiis rotated reversely. For such purposes I have illustrated the following means A vertically movable and rotative shaft 37 is journalled in bearings carried by the casing, a stop 38 on said shaft co-operating with bearin bracket 39 to limit descent of said shaft, 4ig. 5). Said shaft is shown located below the sound arm and provided with a laterally extendin crankarm 37 shown having a sector-like l(laterally disposed head or plate 40 adapted to cooperate with a corresponding plate 41 carried by sound arm 9, shown on the under side thereof, whereby when said shaft is raised and rotated in one direction the sound arm will be raised and correspondingly rotated to lift the needle et from the record 6 and swing the arm to one side thereof, and when said shaft is rotated reversely said arm will be moved back to place the needle over the record near its edge and said shaft will return and descend, A cam 42 is secured upon shaft 25 beneath the lower end of shaft 37 adapted, when shaft 25 is rotated to the right in Fig. 5, to engage and raise shaft 37 and when said shaft is rotated reversely cam 42 will lower shaft 37. Upon shaft 25 is securedv a cam 43 adapted to engage a disk 44 secured on shaft 37, whereby when shaft 25 is rotated to the right in Fig. 5 the cam 42 will first raise shaft 37 to cause plate 40 to engage plate 41, to tilt sound arm 9 upwardly to raise needle a from record 6, and thereupon cam 43 will engage disk 44 to rotate shaft 37 whereby its crank-arm 37 will swing sound arm 9 to carry the needle and the sound box b to one side of the record to permit its removal and the replacement of another record on plate 4.

pon the lower part of -the sound box is pivotally carried a rockable member or segment 45 shown pivotally supported upon a tubular extension 46 from the sound box through which the needle holding screw c operates (Fig. 6). The sound box b may be of any suitable or usual construction. The lower edge 45 of member 45 is curved to rest uponandco-operate with plate 4 or the felt thereon, said member 45 being of such length from its pivot as to rest upon said felt and temporarily retain the needle a raised from record 6. Member 45 has a pinion 47 in mesh with a rack 43 at the ower end of an arm 49 pivotally supported at 5() upon the sound box. The up )er projecting end 49"L of arm 49 has anguiarly related surfaces 49", 49, adapted to co-operate with a spring 51, secured at 52 upon the sound box. When member 45 is in the position shown in Figs. 4 and 6 it will rest upon felt 5 retaining the needle above record 6, but when plate 4 commences to rotate with the record, member 45 will be rotated by said plate and pinion 47 will operate rack 48 and arm 49 to cause spring 51 to snap upon surface 492 to cause arm 49 and rack 4S to in turn operate member 45 suiiciently far to' finally raise it from felt 5 above the plane of record 6 so that needle a4 may descend thereon, (Fig. 5), for the production of music as usual. When the playing has ceased the sound arm and box b will be over the mid-portion of the record, as usual, and member 45 will be raised from the record, as stated, and in order automatically to cause member 45 to assume the starting position (Figs. 4 and 6), I provide an inclined projection 53, shown supported by shelf 8, in

narrati position to engage projection 49d ol arm 49,

to tilt said arm to cause rack 48 to operate pinion 47 to restore member 45 from the music playing position oit Fig. 5 to the starting position ot Fig. 4.A 1llhen the sound arm is next moved toward record 6 during the rotation ot' shaft 25 to the lett in Fig. 5, the l lower part of member 45 will engage the edge oi record 6, but crank arm 37El will continue to rotate, the plate 40 then sliding under late l41, and cams 42, 43 will release sli-att 3 to permit it to descend when shaft 25 comes to rest.

To automatically control the brake devices for the record ll provide the following means :--A curved rack 54 is carried by an arm 55 that is secured to the tubular member 11 and extends beneath plate 7 (Fig. 5), which rack is'in mesh with a pinion 56 whose shait 56a is secured to a ratchet Wheel 57. Said shaft is jour-` nalled on an arm` 58, shown comprising two spaced members9 (Fig. 5), Whlch arm is pivoted at 59 to a bracket 69 below plate 7 and supportedby the casing. The' free ends ot' the, members of arm 58 are rigidly connected by a spacer 58a, (Fig. 7). A spring 61, vshown carried'by bracket .60 and bearing against arm 58, normally retains pinion 56 in mesh With rack 54, and. permits said arm to move laterally for unmeshing oi' said pinion and rack. (Fig. 2). A spring pressed pa'wl 62 is pivotally carried by .a crank arm 63 pivotally supported at 64 upon a late 65 shown also supporting bracket 60, Fig. 1 and 2), which pawl co-operates with ratchet wheel 57 to rotate the latter and pinion 56. An eccentric 66 secured on shaft 23 is rotated with plate 4 and record 6 and actuates arm 63 toI cause pawl 62' to operate ratchet 57 and pinion 56. A spring pressed back stop pawl 67 coeoperates with ratchet 57 to resist its reverse rotation. A lever 68 is pivotally supported at 69 and has a projecting end portion. 68a to engage the adjacent end of arm 58 to retain pinion 56 in mesh with rack 54, when brake member 20 is released from disk 16 (Fig. 1), said projection engaging the opposite side ot said end oi' arm 58 when the brake is applied, (Fig. 2). The lever 68 has a downward projection 68h at the end opposite projection 68EL (which projection 68b may pass through a hole in plate 8), the projection 68b being adapted to engage the lever 21 to shift member 20 to disk'f 16 when projection 68a is over arm 20 (Fig. 2) to retain the brake applied. A spring 70 cooperates with lever .68 to move its projection.

68EL toward arm 58. As the sound arm 9 traverses the record 6 during playing the rack 54 operates with pinion 56 and pawl 62 operates with ratchet 57. needle enters the linal usual circular groove inthe record near its centre the sound arm When the no longer traverses the record but the continued rotation of eccentric |66 with the record causes pavvl 62 to continue to rotate ratchet 57 and pinion 56, whereupon the latter rotating .and operating on the then stationary rack 54 rides on and out of the atter and causes arm 58 to be moved outwardly until it slips past the'end oi projection 68 which passes over said arm, (Fig. 2), finally unmeshing pinion 56 from rack 54, whereupon spring 70 causes lever 68 to move lever 21 causing the latter to operate brake member 20 to engage disk 16 to applythe brake and stop the rotation ot the re ord and other parts. When the brake is to be released tor starting the operation oit a record the lever 68 is tilted (from the positlon of Fig. 2 to the position of Fig. 1) to release arm 58 to permit its movement 'by sprlng 61 to cause re-engagement of pinion 56 with rack 54 and removal of member 26 from brake disk 16. For such purpose ll' provlde a lever 71 pivotall supported at 72 and having a projection 1LL near one end to engageand tilt lever 68. 'lhe lever 71 has a depending extension 71", operative through a hole in plate 8, (Fig. 7), for operation by a cam or member 73 secured on shaft 25. Said cam is adapted to operate lever extension 71b when moving in one direction but not in the reversedirection. Extension 71b is shown provided at its lower end with a nger 74 pivotally connected thereto at 75 and having a stop shoulder 74a normally held against a corresponding stop 71c onextension 71b by a spring 76 that connects said finger with said extension, (Figs. 7 and 8). Finger 74 is free to swing to the side opposite sa1d stops. A spring 77 connecting lever 71 with shelf 8 (or other abutment)normally draws lever 71 against a stop 78 which may be on shelf 8 (Fig. 2). Cam 73 is of such shape and dimension that when shaft 25 is rotated in the direction of arrow a: in Fig. 5 to wind the spring of the motor, the cam 73 will pass finger 74 on its right hand side andtilt it to the left in Fig. 9 without disturbing the brake set against the moton spring tension, and on the return stroke ol said shaft and cam the latter will engage linger 74 on its left hand side (Fig. 9), and will pass beyond said linger with the ciect of swinging lever 71 on its pivot 72 to cause its projectlon 71aL to operate lever .68 to release brake member 20 from disk 16 and to release arm 58, whereupon spring 61 will cause said arm to move to mesh pinion 56 with rack 54, and arm 58 will engage projection 68a to retain. lever 68 and spring 21a will operate lever 21 to move brake member 2O from disk 16 to retain the brake released.

llt will be understood from what has been stated that each time shaft 25 is rotated a be raised, the motor spring will be wound, the sound arm will be released and moved outwardly from the record and return and released at starting position 'and the bra-ke will be released after having been automatically set at the termination of the renderin of a composition by the record and need e. My improvements simplify the use of talking machines since all that the user has to do is to rotate shaft 25 in one direction for a partial revolution, remove and replace a record, and return said shaft to the normal position.

Since shaft 25 can be rotated forth and back by the raising and lowering of the cover 2 it will be understood that such operation of said shaft and cover can be utiing the motor spring may be dispensed with,

and other features of my invention utilized with a motor arranged to have its spring wound in a well known manner, or an electric motor may be used instead of a spring motor.
