MOTOR.

SPECIFICATION forming part of Letters Patent No. 235,880, dated December 28, 1880. Application filed November 26, 1880. (No model.)

To all whom tt may concern:

Be it known that I, BENJAMIN P. KIMBALL, of Elmore, in the county of Ottawa and State of Ohio, have invented certain new and useful Improvements in Motors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled. in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure l is a side elevation of a motor embodying my improvements. Fig. 2 is a rear elevation and Fig. 3 is a vertical longitudinal section, showing one side of the frame removed.

This invention has relation to a motor for driving a fan or sewing-machine or the like and it consists in the improved features of construction and combination hereinafter fully described, and particularly pointed out in the claim.

Referring by letter to the drawings, A designates the frame for supporting the operative mechanism, and B the floor or base to which it is secured. O designates the winding-shaft, and G the power-spring, coiled around it and secured at one end to the same. The other end of the coil-spring is secured to a cross-bar, D, of the frame A.

Upon the shaft 0 is secured a gear-wheel, E, having a ratchet, F, spring G, and detent H, for detaining the spring when wound.

Above the winding-shaft G is a second shaft, 1, provided with a trundle-wheel,J, and a gearwheel, J. The gearwheel E engages with the trundle-wheel J.

wheel, Q, upon a shaft, R,in rear and below the same. This last shaft carries a fly-wheel or balance-wheel, T, and is provided at one end with a crank-arm, U, connected by a pitman, V, to an oscillating lever, W, carrying a fan, X, or connected to a sewing-machine in any suitable manner.

Z designates the key by which the mainspring is wound, and Z is the guard for the oscillating lever W.

The operation of the motor is as follows: The spring U is wound upon the shaft O by means of the key Z, and the retractile power a of the same causes the gear-wheel E to rotate the shaft I through the trundle-wheel J and the gears on this and the other shafts communicate, through their respective trundles, to-

the crank-arm and pitman to the oscillating lever, which operates the fan or sewing-machine to which it is connected. Power may be increased by employing two springs or increasing the strength of the one shown.

The device is simple and inexpensive, and its advantages are obvious.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is

In a motor, the combination of the windingshaft 0, provided with the gear E and ratchet F, spring 0, and detent H, the shaft I, having trundle J and spur-gear J, the shaft 1K, having trundle L and spur-gear M, shaft N, trundle O, and spur-gear 1, shaft R, trundle-wheel Q, and balance-wheel T, crank-arm U, pitman V, and oscillating lever W, constructed and operating substantially as and for the purposes set forth.

In testimony that 1 claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

BENJAMIN P. KIMBALL.
