BENJAMIN F. MOOARTY AND RICHARD E. LINDSAY, OF SEALE, ALABAMA.

HORSE-POWER.

SPECIFICATION forming part of Letters Patent No. 239,181, dated March 22, 1881.

Application filed December 14, 1880 (No model.)

.To all whom it may concern:

Be it known that we, BENJAMIN F. MG- OARTY and RICHARD E. LINDSAY, both of Scale, in the county of Russell and State of Alabama, have invented a new and useful Improvement in Horse-Powers, of which the followingis a specification.

Figure 1, Sheet 1, is a plan view of the improvement, shown as applied to the frame of a gin-house. Fig. 2, Sheet 1, is a side elevation. Fig. 3, Sheet 2, is a side elevation of the frame that carries the gear-wheel shaft and drive-pulley. Fig. 4, Sheet 2, is an end elevation of the frame; and Fig. 5, Sheet 2, is a plan View of a part of the frame.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish horse-powers designed especially for driving cotton-gins, but which can be used with advantage for various other purposes, and which shall be so constructed that they can be built upon the drive-wheels of ordinary horse-powers.

In the accompanying drawings, A. repre sents the posts of a frame of a gin-house.

B are the beams, and O are the sleepers, that support the floor of the gin-room.

D is a block firmly beddedin the ground at the center of the ground-floor.

To the block D is attached a step or socket, E, to receive the pivot formed upon or attached to the lower end of the shaft F, the upper end of which, or a pivot formed upon or attached to the said upper end, revolves in a hearin g, I), attached to the sleepers 0.

To the upper part of the shaft Fare attached radial arms G, which are strengthened in position by the inclined braces H. The upper ends of the braces H are attached to the outer parts of the arms G, and the lower ends of the said braces are attached to the shaft F.

To the upper sides of the outer ends of the arms G is attached a rim, I.

As thus far described the construction is the same as that of an ordinary drive-wheel for a horse-power, except that the ordinary drive-wheel has gear-teeth upon its rim.

To the shaft F, just above the arms G, are attached the inner ends of asecond series of arms, J, of about twice the length of the said arms G.

The middle parts of the arms J rest upon the rim I, and their outer parts are strengthened by the inclined braces K. The upper ends of the braces K are attached to the outer parts of the arms J, and the lower ends of the said braces are attached to the shaft F a little below the lower ends of the braces H.

To the upper side of the outer ends of the arms J is attached a rim, L, to the outer edge of which are attached toothed segments M, forming a gear-wheel. By this construction a large and strong drive-wheel is produced, which has the further advantage that it can be formed from an ordinary drive-wheel by applying to the said ordinary wheel the long arms J, the long braces K, and thelarge rim L.

To the lower part of the shaft F are attached the inner ends of the sweeps N, to the outer ends of which the horses are attached.

To the shaft F, at a little distance from the inner ends of the sweeps N, are attached the inner ends of auxiliary sweeps O, which thus project at an angle with the sweeps N. The

. outer ends of the sweeps N O are connected by a bar, P, as shown in Fig, 1. With this construction the horses of each span are hitched to the sweeps N O, the one in front of the other, so that both horses will travel the same distance, and will thus do the same amount of work.

The teeth of the gearwvheel M mesh into the teeth of the small gear-wheel Q placed upon the vertical shaft R. The teeth of the gearwheel Q are made about three times as long as the teeth of the segments M, and the said gear-wheel Q is secured to the shaftRby keys or other suitable means, so that the gearwheel Q can be adjusted upon the shaft R to give at least three different bearing-places to receive wear from the teeth of the segments M. The gear-wheel Q can be reversed upon the shaft It to expose the other sides of the teeth to wear. The segments M can also be detached and reversed to expose the other sides of their teeth to wear. With this construction the gear-wheels M Q will last much longer than gear-wheels constructed in the ordinary manner. The upper part of the shaft R revolves in bearings formed in or attached to the top and bottom bars of an upright frame, S, the bottom bar of which is secured to the sleepers O by bolts or other suitable means. The lower end of the shaftR revolves in a step or socket attached to or formed in the cross-bar of the hanging frame or stirrup 5 T, the upper ends of the side bars of which which are attached to the bottom bar of the frame S.

To the shaft R, between the bottom and top bars of the frame S, is attached a large pulley or band-wheel,U, around which passes a band,

V. The band V also passes around the pulley W of the gin or other machinery to be driven. The band V also passes around a pulley or roller, X, to guide the said band into I 5 proper position to pass to the pulley W. The

guide-pulley X is pivoted to the top and bottom bars of a frame or sash, Y. The top and bottom bars of the sash Y rest in notches in the adjacent sides of the arms Z attached to the bottom and top bars of the frame S. The notches in the arms Z are made longer than the thickness of the sash Y, and the said sash is secured in place by wedges a driven into the said notches along the top and bottom bars of the said sash Y, so thatthe sash Y,

and with it the guide-pulley X, can be adjusted as the relative positions of the pulley U W may require, to cause the band V to run' even and smooth.

Having thus described our invention, we 0 claim as new and desire to secure by Letters Patent- 1. The combination, with the shaft F, of the arms G, braces H K, rim I, arms J, rim L, and toothed segments M, as shown and described, 3 5 to form an attachment applicable to the driving-wheel of cotton-gin horse-powers.

2. In a horse-power, the combination, with the upright frame S, that carries the shaft R, and the sash Y, that carries the guide-pulley 40 X, of the arms Z, having notches upon their adjacent sides, and the wedges a, substantially as herein shown and described, whereby the guide-pulley can be adjusted as the direction of the band may require, as set forth.
