, D. DI CARLO. v SPRING CIITROLLEO NOISELESS MOTOR FOR OPERATING TALKING AND OTHER MACHINES.

APPLICATION FILED JUNE 26. 1917.

Toall whom t muy concern:

DONATO DI CARLO, OF PHILADELPHIA, PENNSYLVANA.

- sIfnING-Confrnolmn NoIsELEss Moron son OPERATING TALKING AND OTHER MACHINES. A

Be it known that I, DONATO subject of the King of Italy, (but who has de'- 'clared his intention of becomingacitizen of the United States,) and now residing at the city of- Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in SpringControlled Noiseless Motors for Operating Talking and other Machines, of which the following is a specificatlon.

My invention relates to a type of motor for the defined purposes, in whichvthe enor power is stored bythe moans of a colled spring; and inuzsuch connection my present invention relates to certain partic'l ,'ularfeatures in the constructive arrangement of the motor, embracing a iflat coil spring mounted ina stationary casing and horizontally positioned, one end being secured to a rotatable arbor keyed to a gear and 'which latter meshes with a pinion and is operated by a manually actuated horizontally 'arranged hand crank shaft, arranged to one side of the motor; the opposite end of the at coil spring being secured to the stationarycasing and with a vertical main driven shaft which is' controlled in its movement by means of a train of gears, constituting actuating mechanism lof the motor and=with a centrifugal governor in positive connection withsaid mechanism. The assembled arrangement lof the defined motor actuating mechanism is suchas to'be adapted for revolving a turntable located above a platform and the latter is provided with a shiftable stop device and with a speedA changer, which is adapted to be brought periodically into the path of ,the said governor, whereby is provided a practically noiseless motor for use especially for operating in a talking or otherv similar machine. f;

The particular features of novelty of the motor of my present application over Letters Patent ranted to me under date of July 5 25th, 1911,' o. 998,757 resides first, in the noiseless character thereof; second, in the horizontal arrangement of the motor with` its operating mechanism land in the simplifying of the same as designed, for especially adapting such motor for the operation of :a

talkm o'r similar machine; and third, to the 'inclosmg of the coiled leaf spring in a sta# tionary casing for winding and unwinding and wlth the actuatedl gearv and pinion mechspeeiacauon of Letters lraient.

` claimed.

The nature and scope of'my present invention will be more fully understood from the following description taken yin connection with the accompanying drawings forming part hereof, in which--.

Figure 1, is an inverted top or plan view of a motor and actuated mechanism mounted in a framing, embodying essential features of my invention and showing also the platform with the revoluble turntable and speed change device.

Fig. 2,' is an inverted vertical sectional view through the motor and actuated mechanism of the same.

Fig. 3, is a fragmentary plan view of the stopping andl speed change devices ofthe motor.

Fig. 4, is an end view," showing the structural arrangement of the speed change and stopping devices, and

Fig. 5, is a fragmentary sectional view. partly in elevation of the motor and its actuating mechanism.

Referring to the drawings a, is the incased fiat coil spring, onel end bolted to the casing al, and the other to a rotatable arbor a2, journaled in said casing and extending through the opposite end ofthe said casing and to which is keyed or otherwise secured Ation between the gears b* and c being the usual ratchet wheelV c3 and spring-controlled pawls a1, c2, permittin winding operation of the spring Without riving gear c. d, is a train of connected gears and pinions successively actuated by the gear c, and therewith the vertical main driven ball bearing shaft e, projecting `above 'thetop of the i skeleton framing as, and with a removable shaft e, for permitting of the rotating of" the same. At one corner of the platform f, is arranged a lever h, carrying a buifer k1, at the free end and a milled lock-bolt h2, for operatively controlling the said lever. The said lever is adapted to be shifted in substantially the arcvof a circle, to engage the perimeter of the revoluble turntable to stop o1' slow down its travel. TheA opposite Corner of the plaftorm f, is provided with a slanting or inclining lever' rod i, With a handle 1, at one end and buffer 2, at the yopposite end. This handle extends downward through a slot f2, in the said platform and is adapted by shlfting the handle either back or forth to` bring the buffer into either close proximity to or shift it some distance from the centrifugal governor j, to be thereby momentarily engaged. The governor y', is journaled in a bearing a, of the skeleton framing at It also is provided with a Worm d1, meshing with one of the pinions as d2, of the train of gear and pinion mechanism d, of the hereinbefore described motor, and actuated thereby, when the flat-coil spring a, is wound up as already explained, in any Well understood manner. The device just `explained is adapted to permit of the quick Y' change in thevspeed of travel of the turntable g, as may be required, in operations of I the talking machine for deriving the desired musical or other effects therefrom.

Having thus described the nature and objects of my invention What I claim asnew and desire to secure by Letters Patent is A spring controlled motor `for phonographs or the like, comprising a fixed casing, a fiat spring coiled in said casing, an j arbor rotatably -mounted in the caslng and having one end of the spring secured thereto, a Winding gear fixed to the, arbor and having beveled teeth, a Windingmeans cooperating with the beveled teeth of the y DONATO CARLO.
