IMPROVEMENT IN MACHINE FOR APPLYING ANIMAL POWER.

'alge Stimuli atenta it iu tlgrst trttat Qttoit mit mating pat tf tigt time TO ALL PERSONS T O WHO THESE PRESENTS SHALL COME:

Be it known that I, JONATHAN DnAnBonN, of Seabrook, in the county of Rockingham, and State of New Hampshire, have invented an improved Machine for Applying Animal Power to the production of useful effects; and I do hereby declare the same to be fully described iu the following specification, and represented in the accompanying drawings, of whichi i Figure 1 is a top view.

Figure 2 a vertical section; and

Figure 3, an end elevation of my said invention.

In such drawings, A denotes a shaft inclined to the horizon,'and having its journals a duly supported in boxes or bearings, sustained by a frame, B. On this shaft, and at right angles to and concentric with it, is fixed a circular platform orwheel, C, provided with a circular fence or fender, D, raised on it, concentri'cally with the shaft. Eucompassng the wheel C, and elevatcdon the top hoard or platform, e, ot' the frame B, is a circular guard, E, provided witlra gateway or opening, F, leading through its lowest part. Projecting from the guard E, and fixed to it at its middle, is an auxiliary platform, G, which extends' over the fender D, and covers it at a short distance from it. The shaft A runs through a hole, 7L, made through the platform G. Such platform is also supported by means of a hanger, z', extended down from the cross-giri; c of the frame B. If desirable, the wheel may have a series of friction-wheels, Z-l l, applied to journals projecting from its periphery, s'uch wheels being to run on the platform c, or a circular railing fixed thereon. Below the platform e the shaft A has a bcvelled gear, H, fixed on it to engage with a bvelled pinion, I, fixed on akshaft, K. To this shaft'any mechanism may be applied for transferringrotary motion of the shaft to any mechanical object, whether such he a circular saw, as shown at L, or any other. The mechanism so applied for effecting the rotation of the saw being two sprocket-wheels, M N, and an endless chain, O, one wheel being-fixed on the saw-shaft P, and

the other on the shaft K. I When one or more persons or animals may attempt to walk upon and up the wheel- C, on either side of `the shaft, that is, oneither of the spaces R S, the wheel will b e put in revolution, as the gravitatingpower of the person or persons, animal or animals, as the case may be, will cause thewheel to revolve and put the shaft in revolution. The platform G is to support a personwhilethe wheel may be revolving, for, when the velocity of the wheel may be too great, t'he person can jump ofi' the wheel and upon the platform, or sit down thereon.

I claim the combination and arrangement of the inclined shaft A, the wheel C, the guard E, and the platform G. v l

I also claim the combination of the shaft A, the wheel C, the guard E, the fender D, and the platform G.

I also claim the combination of the bevelled gears H I, the shaft K, the shaftA, the wheel C, the guard E, and the platform G, the whole being arranged and so as to operate as specified. p
