UNITED STATES PATENT OErueEc CHARLESA E. MAGARTHY, OF FORSYTH, GEORGIA.

IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent No. 201,807, dated March 26, 1878; Reissue No. 8,366, dated To all whom it may concern:

Be it known that I, CHARLES E. MAGAR- THY, of Forsyth, in the county of Monroe and State of Georgia, have invented a new and Improved Horse-Power; and I do hereby de clare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming part of this specification, in which the ligure is a side view of the horse-power with the frame in vertical section.

The object of my invention is to provide a cheap and simple form of horse-power, such as niayreadily be constructed upon plantations for thrashing or grinding grain or ginning cotton.

To this end my invention consists in arranging a horizontal band-wheel on the kingpost, a tension-pulley, a speedpulley, and an endless-rope belt in such relation that while two of the wheels or pulleys are in the same plane and distend the belt, the third is located between the other two in a plane at right angles thereto, and has one side of the belt wrapped entirely around its periphery.

As the best illustration of my invention, A represents the frame-work of the horsefpower, in which is arranged, in suitable bearin gs, the vertical king-post B, carrying one or more levers, C, to which the draft-connection of the team is applied. At a suitable height above the lever is firmly fixed to the king-post a large horizontal band-wheel, D, having upon its periphery a groove to receive the endlessrope belt. E is said belt, which is wrapped once around the kin g-post wheel D, and is then extended around a Speedpulley, F, on one side and a tension-pulley, G, upon the other. The said speed-pulley F is located upon a shaft, H, carrying a band-pulley, I, designed to receive the band connecting with the gin, thrasher, or mill. The tension-pulley Gr is journaled in a swinging frame, J, pivoted at the top to the frame-work by means of a slot and bolt, and is strained to tighten the belt by means of a weight, L, connected to the said swinging frame by a cord, K, which passes over a roller, M, xed in a frame, N.

The advantages of this arrangement of horsepower are to be found in its cheapness, sim- August 13, 1878 application tiled July 15, 1878.

plicity, and absence ot' noise. The endless-rope belt, also, while costing notv more than onesixth as much as a rubber band, possesses the further advantage, in this peculiar arrangement of parts, of transmitting power from one band-wheel to another, at right angles thereto, without the objectionable twisting of the band and the tendency of the same to run oi the wheel.

I am aware ot; the fact that an endless-rope belt has been heretofore driven by a series of radial reel-arms having forks at their extremities to receive the belt, which reel-arms were arranged in a similar relation to a tension and speed pulley, as in my invention. The reelarms in such relation are objectionable, however, for the reason that they have a tendency to throw the rope first to one side, and then to the other, of the pulley to which it is t'ed, thus necessitating an intermediate guide-pulley to cause the rope to be fed in a straight line to the pulley receiving it from the reel. It' there is any sag or looseness in the rope, also, which is not taken up by the tension-pulley, the seating of the rope in the forks of the reel is uncertain. By using a main pulley or Amaster-wheel having a continuous circular periphery and lan ge it will be seen that the intermediate pulley may be arranged tangentially to the rope passing from the pulleys at the opposite ends, and the rope is paid out from the master-wheel at a tangent and in a true and unvarying line to the pulley to which it is fed, thus dispensing with intermediate guidepulleys, and also avoiding the throwing of the rope rst to one side and then the other, as occurs when fed directly from the reel-arms. I therefore only claim the combination described, when the master-wheel has a continuous circular periphery and ange, and when the intermediate pulley (which is at right angles to the end pulleys) is tangential to the side of the belt extended from the two end pulleys.

Having thus described my invention, what I claim as new is The improved horse-power, consisting of the combination of an endless-rope belt, a tensionpulley, a speed-pulley, and a horizontal pula ley or band wheel ony the hingpost, having a continuous periphery and flange, two of said two pulleys, substantially as shown and depulleys being in the same plane and distendscribed.
