The invention will first be described in connection vviththe accompanyingdrarvings,

One ofthe barrels 5 carriesva spurgeari Whiclnthrough al usual gear train iFigfl, rotates f an arbor? vvhiclr projects upward through the to fboard Fig. 2 Fi the under side of Whichfthe plate `1 is secured plate'l and through `a motor ndicated :in dotted lines) to in vany .desired manner. i The upperfendfyof theearbor 7 yis adapted tocarry aI disci-like "turntable l(not shown),; on which a record disc is supported. The arbor 7 `is rotated Uby they unwinding of the springs inthe barrels, it being-understood that the shaft 3 is'normally stationary during the unvvinding fthespring in thefbarrel y5, and rotated I by. the unvvindingiof the spring intheibarrel 4..` :It-Will also be understood that the usual- V'governing mechanism may be placed be# v:tween thespring barrels'and the arbor 7 which holdsthe drum stationary during the Winding of` thel motor.

`The top/plate 1 has thiclrene'dfportion U8 in which afrecess 9. The bottom v10 '-off.the1re'cess is provided with a cylindrical opening-11 thereinin axial alignment vvith fth'espring barrels 4I and 5;' i 1 aLoosely-.carried on'the shaft 3, Iandmlisy.posed `Within the recess v9, isayvorm yvvheel 12 provided `With avr hub 13 Vvvhich cooperates fivithithe' openingll to center the shaft Bin Vthe opening. The hubfrests upon apad onl the upper end ofthe spring barrel 4. l

The yhub is .provided lwithr tvvo diametrieallyf disposed, axially extending

pins

.which are adapted to cooperate `With avp'air from the endof thelsprin'g Ibarrely y4, as shown. A screvv ,16 carried inthep'late' 1 prevents Aremoval from' the shaft .3 of 4the Sworrn Wheel.

Aforithereception of the usual Winding crank :(not shown) i The shaft '17 extends through the recess 9 and carries a Worm 18'1inemesh vvithfthe -vvorrn Wheel '12. When thefplate 1 is secured to thennder sideo'fthev .motor fboard,l as lisy common', the recess Will be .closediand dustkand dirt. vvillbezprevented of'similarly disposed' pinsk:15, l15projecting projeetsover thevtop of the Worin Wheel. and

Vrwvinding shaft 17 is journaledito the i `plate -1 :and projects outwardly to v'one side i rfrom entering thelrfccess. @'IheWinding4 shaft 17 is provided with the usual awl and ratchet mechanism for preventing aclrward rotation of the spring.

The operation of the device is as follows: In winding the motor the operator turns the f shaft 17, thereby communicating motion to the worin-wheel 12 rthrough the worm 18 thereby rotating the worm-wheel 12 and causing the lugs 14 on the hub 18 to engage the lugs 15 on the top of the barrel `4,

thereby rotating the barrel 4, the barrel 5 remaining stationary by reason of its interlocking with the table-operating gearing andthe usual brake mechanism in machines of this sort.. rlhe barrel 4 being thus rotated, and the barrel 5 remaining stationary,

the rotation of the barrel 4 by means of the connection of the springv therein with the shaft 3, the shaft 3 will be rotated with the barrel, and thereby effect the winding of the spring in the barrel 5. When the spring in the barrel' has been sufficiently rotated to fully compress the spring therein, the shaft 3 will become stationary,l and the further rotation of the barrel 4 will wind the spring in said barrel 4. Vhen the Vspringin barrel 4 is wound to its fullest extent the o erator `releases the windinoq 3 shaft, which is prevented from backwardy rotation by the usual. pawl and ratchet mechanism. TWhen the usual brake mechanism of the machine is released, the unwinding of the springs will cause the

lugs

14 and 15, upon the backward movement of Athe worin-wheel 12, to come into engagement, and thus 'hold the barrel 4 stationary and permit the spring in the barrel 5 to unwind, and rotate the talking machine table, andas soon as the spring in barrel 5 unwinds to its fullest extent, the spring vin the barrel 4' will unwind and rotate the shaft 3 and thereby rotate barrel 5 through its connection with the shaft by the spring therein, and further rotate the turn-table of v lthe machine, through the gearing 6 carried by the barrel. 5. f

IVhile I have illustrated my invention in connection with a talking machine motor, I wish it distinctly understood that the same is not to be so limited.

It is obvious from the foregoing descripl tion that I have constructed a very novel and til) it understood that my invention is not confined to the particular' form of apparatus herein shown and described, the same being merely illustrative, and that the invention can be carried out in other ways without departing from the spirit of my invention, and, therefore, I claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means of which objects of my invention are attained, and the new results accomplished, as herein set forth, as it is obvious that. the particular embodiment herein shown and described is only one of many that can be employed to attain these objects and accomplish these results.
