IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 120,678, dated November 7, 1871; reissueNo. 5,226, dated January 7, 1873 reissue No. 6,978, dated March '7,

1876; application filed February 12, 1876.

To all. whom it may concern Be it known that I, HEMPHILL Tipton, in the county of Tipton, State of Tennessee, formerly of Shelby Station, in the county of Shelby and State of Tennessee, have invented a new and Improved Horse-Power; and do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, in which-- Figure 1 represents a side elevation of my invention, showing the wheel in a horizontal position. Fig. 2 is a vertical transverse sectional representation, showing the wheel in an inclined position. Fig.3 is a representation of my invention in horizontal section, taken on the plane of line as m, Fig. 1.

This invention has relation to certain improvements in horse'powers; and it consists in the novel arrangement of the draitrope, windlass, and rope, in connection with the frame of the horse-power, and in he construction and novel arrangement of the wheelrimming and braces, all substantially as hereinafter more fully described.

A in the drawing represents the power wheel of my improved horse-power. B is the shaft upon which it'is mounted. The lower end of this shaft has ajournal, which rests. in a step, a, which is secured in the bed of the supporting-frame G. The upper end of the shaft has a gudgeon-plate, B, the journal of which turns in a movable cross piece, I), which is held between longitudinal This gudgeoi-i-plate has a shank, Z, which is driven into the end of the shaft, bringing the gudgeon-plate close down to the latter, allowing it to be fastened by four spikes driven into the shaft through holes in the plates. Other holes in the plate near its edge, receive the ends of the oblique wheel-brace rodsO, which are secured to the gudgeonplate by means of nuts turned on their ends, as shown. The gudgeon-plate and braces thus tend to mutually support each other.

When the wheel is in a horizontal position it can be used as a tread-wheel, its surface being properly floored for that purpose.

When the flooring is removed the wheel can be used as a draft-wheel by hitching the SMITH,

7 animal to its radial arms 6 e. The periphof cry of the wheel A is toothed, and meshes into the teeth of a pinion, that is mounted upon a vertical shaft, D.

In whatever manner the wheel A may be revolvedit will impart rotary motion to the shaft D, and thence to the machinery with which it is connected.

The wheel has a rim, A, made of planks, bent to the circle of the wheel. or toothed segments are bolted to this rim. The shaft has its bearings in aframe, E, which is, at g, pivoted to the frame 0.

When the wheel A is to be inclined the cross-piece b is'shifted in the beams (1 into the position shown in Fig. 2. The frame E is then also swung to the side and locked by wedges h, so that the shafts B and D will be parallel. for the reception of the several positions.

The wheel can thus be used either inclined or horizontally, and in the latter position either as a tread-wheel or draft-wheel. When used as a tread-wheel the rope F is stretched along the frame G, and connected with a Windlass, G, which may have, a ratchet and pawl, to be prevented from unwinding. The horses are hitched to this rope, the Windlass serving to equalize their power.

In connection with the rope, I may use weights H, suspended at the corners of the frame 0. The horses are hitched to these weights, and their breast-straps connected with the rope. Their power will be increased the more they draw on the weights while treading on the wheel.

This arrangement of rope and weights serves properly to control the animals during action, and dispense with the driver.

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

1. The draft-rope F and Windlass G applied to the frame 0 of a horse-power, substantially as and for the purpose specified.

-2. The draft-weight H applied to the horsepower, in combination with the rope F, as specified.

3. The horse-power wheel A, having the bent wood rim A, with the teeth bolted thereto, substantially as described.

The shaft 13, having the gudgeon-plate B, the journal of which turns in a movable cross-piece, b, adjustable in the notched longitudinal pieces (Z d, in combination with the pivoted frame E, substantially as described, and for the purpose set forth.

In testimony that I claim the-above I havehereunto subscribed my name in the presenct oftwo witnesses.

HEMPHILL SMITH.
