UNITED STATES PATENT OFFICE.

THOMAS H. HOSKINGS, OF DETROIT, MICHIGAN.

MACHINE FOB THE APPLICATION OF MAN-POWEB.

Specification of Letters Patent No. 32,369, dated May 21, 1861.

To all whom it may concern:

Be it known that I, Thomas H. Hoskings, of Detroit, in the county of Wayne and State of Michigan, have invented a new and 5 Improved Machine, which I denominate “ Hoskings’ Man-Power.” a machine which is intended to facilitate the application of the potver of a man to the production of rotary motion; and I do hereby declare that 10 the following is a full and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1, is a side view, and Fig. 2, a top 15 view of said machine.

The main wheel A of my improved manpower communicates its motion to the pulley G, on the shaft D', in the following manner, viz: The main wheel A, commu20 nicates its motion directly to the small wheel B, on the shaft B'; and the large wheel C, upon the shaft B', communicates its motion directly to the small wheel D, on the said shaft D'. Power is applied to the main 25 wheel A, of my improved man-power in the following manner, viz: The frame I, I, is suspended to the periphery of the main wheel A, by means of the curved arm H. which projects forward from its jointed con30 nection with the said frame and is made to take hold of the teeth of the said main wheel A, by means of the pawl k, which is jointed to the extremity of the said curved arm.

The shaft J, which is combined with the suspended frame I, I, carries the toothedwheels ,K, K, and L, which are so arranged thereupon that while the smaller central wheel L, gears into the teeth of the main 40 wheel A, the wheels K, K, rotate on each side of the face of said driving wheel. The said frame I, I, also carries the shaft N, in suitable 'bearings, which shaft carries two toothed wheels Μ, M, in such positions that they gear into the toothed-wheels K, K, on 45 the shaft J, and the said shaft N, also carries upon its extremities the hand driving wheels P, P. The said frame I, I, also has a platform Q, combined therewith in the manner represented in Fig. 1; which plat- 50 form is placed in such a position that a man standing thereupon can advantageously take hold of the driving wheels P, P. It will therefore be perceived that a man standing upon the platform Q, and exerting his com- 55 bined strength and weight upon the wheels ^p,^p, can elevate the frame I, I, to the position represented in Fig. 1, provided a proper amount of resistance is at the same time exerted by the pulley G; and then by continu- 60 ing to exert his strength, in connection with his weight·., the operator can retain the said frame I, I, in the aforesaid elevated position, and by so doing he will impart a steady and uniform amount of motion and power 65 to the pulley G, through the medium of the main wheel A, and the auxiliary wheels B, C and D.
