UNITED STATES ADAM M. FRIEND, OF RAWLINS, IVYOMING TERRITORY.

MANLlAL MOTOR.

SPECIFICATION forming part of Letters Patent No. 364,406,

dated June 7,1887.

Application filed May-11, 1886. Serial No. 201,884. (Model) To all whom it may concern.-

Be it known that I, ADAM M. FRIEND, of Rawlins, in the county of Carbon, \Vyoming Territory, have invented a new and useful Improvement in Manual Motors, of which the following is a specification.

The invention is a combined hand and foot power motor, for use for driving printing presses or other light stationary machinery; also for propelling vehicles of various kinds. It is so constructed that both the weight and strength of the operatormay be applied and utilized for propulsive effect.

The invention is fully described hereinafter, and the features of patcntable novelty indicated in the claims.

In ihedrawings, Figurel is aside view with one of the sides of the frame detached. Fig. 2 is a plan view, the levers being,however, not in exactly the same position as in Fig. 1. Fig. 3 is a detail view showing an alternative position of one of the hand.- levers and its pawl.

In the frame F are j ournaled three horizontal shafts, Nos.1 2 3. No. 1 is the drivingsliaft; No.3, the shaft from which power is taken off, and No. 2 is the intermediate or power-transmitting shaft. On the shaft 1 is fixed a driving-gear, G, which meshes with a pinion, I, on shaft 2, and a gear, G, on thelatter in turn meshes with a pinion, P, on shaft 3. In this arrangement of shafts and gears there is of course no novel feature.

The operator of this motor bestrides scat S, so that his feet rest on and work the two treadlelevers T, while he grasps the two hand-levers II. These two sets of levers are jonrnaled loosely on shaft 1, there being one treadle-lever and one hand lever on each side of the driving-gear G. In theforks of the levers is a cogwheel or ratchet, R, whichis fixed on shaft 1. Each hand-lever H has a pawl, 19, that is pivoted in its fork, the latter being of sufficient length, relatively, to allow said pawl to swing through it, so that the lever may be worked either way to rotate the gear G in either direction. The alternative position of the pawl is shown in Fig. 3. The free or working end of the pawl 19 is made fiat, so that right-angular shoulders are provided to engage the teeth of wheel R. The treadle-levers T also have pawls p pivoted in their forks, and adapted to likewise engage the toothed wheels It. Footlevers f are pivoted in the outer ends of treadlelevers T, and the part of them that projects above the pivot serves as a foot block or rest, and the longer arm below acts on the pawl 11 to raise it into engagement with the wheel R.

Tosupport each treadlc T in position to be conveniently reached by the feet of the operator, also to raise'it after each depression, I employ a spiral spring, 8, which is pendent from a rocker, 7, pivoted on seat S. Obviously, when nopressure is applied to foot-leversf, the pawls 1) will hang down out of action, and the hand-levers II may be used alone to operate the motor; or one treadleT may be used alone, or one hand-lever and treadle may be used together, or both trcadles and both hand levers, as preferred or required. Thus the operator may applylittleforce, or as much as he is capable of, according to conditions. It will be noted that when he pulls on ahandlever, H, he will naturally press downward with his foot on a treadle-lever, thus applying force with both, and to a greater degree than would be otherwise possible. In brief, both the weight and strength of the operator are utilized in direct application of force to the motor.

As before intimated, the pawls of handlevers H may be swung over the shaft 1 and the levers worked from a seat (not shown) placed on that side. Other trcadles may be also provided on the side opposite that where the seat is shown located.

Vhat I claim is- 1. In a mechanical motor, the combination of a freely-vibrating hand-lever and a treadle having pawls, as shown,with a toothed wheel, and a rotatable shaft on which the toothed wheel is fixed and from which shaft power is transmitted, as set forth.

. 2. In a mechanical motor, the combination, with a drivingshaft, 1, having toothed wheels R fixed thereon, of the hand-levers H and treadlelevers T, having pawls adapted to en gage said wheels, and means for supportingsaid treadle-levers, as shown and described.

The combination, with the driving-shaft 1, having toothed wheels R fixed thereon, of hand-levers H, which are hung loosely on said shaft and constructed with forks embracing said wheels, and the pawls which are pivoted in said forks and made of the length specified, whereby the levers are adapted to be reversed for the purpose of working the motor in the reverse direction, as set forth.

4. The combination, with a shaft and toothed IO wheel, of the treadleleve r T, a pawl and footlever,f, pivoted thereto, the latter being arranged as specified, whereby it is adapted to raise the pawlinto engagement with said wheel when pressure is applied to the foot-lever, as shown and described.
