JOSEPH REPETTI, OF BUENA VISTA, NEV JERSEY.

MOTOR.

SPECIFICATION forming part of Letters Patent No. 451,249, dated Apri1 28, 1891.

Application filed August 16, 1890. Serial No. 362,204. (No model.)

To all whom, it may concern.-

Be it known that I, JOSEPH REPETTI, a citizen of the United States, residing at Buena Vista township, in the county of Atlantic and State of New Jersey, have invented a new and useful Improvement in Motors, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to improvements in motors; and it consists, first, of means, substantially as described, connecting the motorwinding mechanism and the motor and permitting the operation of the former without the operation or continuous winding of the latter; second, of the combination of parts hereinafter set forth.

Figure 1 represents a partly side and a partly 1ongitudinally-sectional view of the mechanism embracing my invention. Fig. 2 represents an end view of the same. Fig. 3 represents a modification of the mechanism for operating the winding-shaft.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a spring-motor, and B a rotatable wheel connected with mechanism operating therewith.

O designates a rotary shaft having an angular opening at one end for the insertion of the angular end D of the shaft 1) of the motor-spring, said shaft 0 having its other end suitably journaled in an upright E.

Rigidly secured to the shaft C is a disk F, and mounted on the said shaft is a gear-wheel G, which meshes with and receives rotary motion from a pinion H on a rotary shaft J, which is operated by the action of any suitable winding device connected therewith.

To bind the wheel G to the shaft 0, so that the latter will rotate therewith and thus wind the spring of the motorA and yet permit the free rotation of the wheel on the shaft when the spring is wound up, the hub of the wheel is loosely mounted on the shaft and a fiat portion K thereof is placed against the disk F and forced against the same by means of a collar L, spiral spring M, and nut N, the latter working on a screw-threaded portion of the shaft 0. A jam-nut P secures the nut N in place. It will be seen that as long as the spring of the motor is free to wind its shaft, owing to the frictional contact of the disk F and wheel G, will rotate with the shaft 0 when the latter is rotating; but when the spring is wound up so that its shaft will no longer rotate the wheel G will slip on the disk F, so that it will rotate'on the shaft 0, thus permitting the rotation of the shaft J and the operation of the motor which may be used without disconnecting the motor from the said shaft.

If the winding mechanism and the motor were rigidly connected, the continued rotation of the rotatable wheel B when the spring is wound would necessitate a breaking of the parts, as is readily understood.

Instead of the pinion H and gear-wheel G for communicating motion to the shaft O, the mechanism shown in Fig. 3 maybe employed. A pulley R is mounted on an independent winding-shaft and has a link S eccentrically connected therewith and with a lever T, mounted on the hub of a ratchet-wheel U, which is mounted on the shaft 0, the said lever carrying a spring-pressed pawlengaging the teeth of the said ratchet-wheel and intermittent-1y rotating it and the shaft. By means of the mechanism thus described an intermittent motion is changed into a continuous motion.

The motor-spring V has one of its ends secured to its shaft D and the other end to the drum V, which communicates motion to the gearing \/V of the said motor. By thus arranging and connecting the parts the motor may operate during the time of its winding.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A motor having a spring and a shaft, a winding mechanism therefor having a shaft with a friction-disk thereon, and a gear-wheel loosely mounted on said second-named shaft in contact with said friction-disk, and mechanism, substantially as described, for rotating said gear-wheel, said parts being combined substantially as stated.

2. A motor having a coiled spring with a winding-shaft, in combination with a rotatable shaft connected with said winding-shaft, a friction-disk secured to said rotatable shaft, a winding mechanism having a shaft with a pinion thereon, a wheel with hub loosely mounted on said rotatable shaft and meshing with the said pinion, and a spring bearing against the said wheel, substantially as described.

3. A motor having a shaft for the spring 5 thereof, in combination with a shaft having a gear-Wheel mounted thereon, said gear-wheel being adapted to be moved into frictional contact with a disk rigidly secured to said last-named shaft, thelatter shaft being adapt- [0 ed to rotate with the shaft of the motor, sub-,

stantially as described.

4:. A motor having a shaft with a second shaft inline with the first shaft and adapted to rotate therewith, a friction-disk on said 15 second shaft, a rotary gear-wheel loosely mounted on said second shaft and in contact
