Be it known that I, M. A. RICHARDSON, of Sherman, inthe county of Chautauqua, and State of New York,

.have invented a certain new and useful Improvement in Horse-Powers; nndI do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, Imaking partei' this specification.

Figure 1 is a side elevation of my apparatus, applied to a building.

Figure 2 an inside elevation.

Figure 3 a'plan of the gearing turned'bottom upward.v

Figure el a view of the turning-shaft and forked sweep.

Like letters of reference indicate corresponding parts in allthe'gures.

My invention consists in thel application of the powerto't-ho side of a building, in such a manner that the outer ond of the supporting-beam is iiexible, or ,capable Aof being raised, to allow the driving-shaft tobe removed nt pleasure; it also consists in the construction and arrangement of the inner or crank-end of the apparatus for transferring the power;` it further consists in a cord passing from the inside of the building outward,down Ward through an eye in the main spurfwhcel and top ofthe driving-sl1aft, and thence connecting with a belt passing around the horses belly, whereby a spur may-bc applied to the'horse fromthe inside, to quickenv his motion, without the necessity of an extra attendant.

In the drawings, Aiindicates the main beam or arm, attached to the side of a. building, so as to have a degreeof vertical movement or spring,gus indicated in red lines in fig. 1. With the outer'end of this beam connects an angular horizontal brace, C, and a vertical brace, B, the latter having a slot and screw, a b., which allow the verticalmovement of the beam, as aforesaid. The outer end of the beam sustains a set of gearing, D GF H, from which a shaft, I, transfers the power ter the inside4 of the building.

The bearing of spur-wheel D is provided with a square eye or socket, d, in which hsets one end oftdrivngshaft or spindle E, the opposite end being stepped in bearingf, in the groundL l A sweep, P, for attaching 'the horse, is secured to the shaft by means of forks or branches, t t, and screws, s s, by which means the sweep can be tightened, so that when turned up (red lines, tig. 1,) it'will retain itsposi tion, out of th'e way, when not in use.

The great advantage of this construction consists in so connecting and attaching the beam A, that it can be' raised, as in red lines, to allow the shaft E to be removed.

As this power is intended to be connected with some building, this arrangement is very essential, since it is frequently necessary to drive a team' near the building, under the beam, especially if it be anl out-house 4or barn. The forming of the socket rl in spur-wheel D, allows this to be effected with the greatest facility.

At the same time that the beam is thus capable of rising, it is firmly stayed by the Aangular verticalv and' horizontal braces B- C, so that it cannot be racked bythe strain.x 4

This arrangement of attaching the power to thevside of the building, so that the drivingshaft may be I applied or removed at pleasure, I believe to be original with myself.

The inner end ofthe shaft I has a pulley, J, and also a crank-eruit, If, held in place by nut and washer rj), which allows the crank-arm, at any time, to be removed, for the use of the pulley alone. i

'lhc crank-arm has, at one end, a wrist-pin, Lfwhich rests in slot g of rock-lever M, pivoted at u', and it has, in the centre, an adjusting-slot or holes, m, for varying thelength ofthe operating-end, and at the opposite extremity it has a slot, n, in which rests a eounterbalancna-weight,o. I i l By this arrangement -the leverage of the crank can be adjusted at pleasure, by one movement of the cranks arm out or in, und the counterbalance-weight also adjusted in the same manner. lWhen it is desired not te use the crank, but employ the pulley, the former is removed with great ease,- and the setting of the nut up close and tight against the end of the pulley, ixes it firm in place. By this arrangement either a crank or pulley is secured to the end of the shaft I, to impart'motion either separately or in conjunction, in the simplest and most effective manner. l

The employment of the nut and washer rp, enables me to so gauge the power of the crank as to avoid any breakage by an undue degree of resistance; for by screwing up to the desired degree, if the resistance is greater than a given amount, the crank will turn back upon the shaft I, free of the holding-screw'. This also `enables me to raise or lower the rock-lever, as may be desired, for instance, in ehurns, toadjust the height of the dasher, as' shown in the drawing. I i i A cord, g,'passes outward from-the inside of the building, through a thimble, 7c, thence to the extremity of beam A, and down 'through socket cl of spur-gear D, thence' through a central hole, c, in top'of drivingshaft E, and nally comes 'out through the side of the shaft. At this pointl is interposed a swivel, h, when a continuatiomj, passes on and connects with a belt passing around the belly ofthe horse, said belt having any suitable spur, to prick the horse when the cord is drawn taut.

By this means the operator, standing inside the building, can apply the'spur at any timeto the horse outside, saving the necessity of a second person for the purpose.

The passing of the cord through the central eye of the driving-shaft, prevents'any winding of the cord upon said shaft, and the employment'of swivel L obviates or compensates for all twisting of the cord. Therefore this peculiar arrangement insures a constant spur to the horseas he passes the circle, without winding or twistingan effect that can be produced by no other arrangement within' my knowledge.

WhatIclaim as my invention, and desire to secure by Letters Patent, is

1. 'lhe projecting beam A, supporting the gearing D G F H, and stayed by braces B C, in combination.

with the removable driving-shaft E, resting in square-socket d of the spur-wheel, and supporting the forked sweep P, the whole being specially-arranged for allowing the displacement ofthe said driving-shaft, as herein set forth. 2. The cord g, passing centrally through the top of the driving-shaft, and having a swivel, L, beneath, to prevent twisting, when combined with a belt passing around the horses belly, in the manner and for the purpose specified.

3. The special construction and .arrangement of the apparatus,` as a whole, consisting of projecting beam A, braces B O, gearing D G F H, removable shaft E, forked sweep P, pulley J, crank K, and the-spurring-cord g, operatingin the manner and for the purpose specified.

In witness4 whereof, I have hereunto signed my name in the presence of two subscribing witnesses.

M. A. RICHARDSON. Witnesses:

ALBERT Huisnr, i .R. DRAKE.
