Lette/rs Patent No. 92,474, dated July 13, 1869.

IMPROVED HORSE-POWER,

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom it may concern Bc it known that we, CYRUs ROBERTS and J cnn A. THROP, of Three Riversin the county of St. Joseph, and State of Michigan, have invented certain new and useful Improvements in Horse-Powers, of lwhich the following is a full, clear, and exact description, reference being had to the accompanying drawings, which make part of this specitication, and in which- Figure l represents a plan or top view of a horsepower embracing our improvements, when staked in position for operation, and

Figure 2, a vertical longitudinal section of the same, at the line :u a: of fig. 1.

Our improvements are shown as applied to a mounted horse-power, or one which is placed upon wheels for convenience of transportation, but are equally applicable to a down power, the objects of our invention being accomplished in either class of machines, when in operation. 5

The improvements claimed under this patent consist- First, in a line-shaft, extending outward at the rear of the machine, and connected, hy a flexible coupling, with 'a tumbling-rod, mounted upon aframe hinged thereto, in such manner that the angle of the tumbling-rod with the line-shaft may be varied at pleasure, to answer the requirements of the work; and when not in operation, the frame maybe turned up, and used as a rack for supporting the levers, braces, 85C., of the horsepower, while being transported. Second,"iu the employment of diagonal braces, rml y connecting the bed-plate to the frame, the same being arranged iu the direction of the lstrain to which the former is subjected by the pull of the horses when operating the power, and serving to obviate liability of its working loose or becoming disconnected.

o rl`hird, in au improved method'ofstaking the machine to the gro -when in operation, whereby both lateral and end-. i of the same are prevented,and the power of the"'h"orses effectively exerted, without risk of altering its position, as hereinafter more fully set forth.

In the accompanying drawings, which show a con-I venient arrangement ot' parts for carrying out the objects of our invention, A represents the frame of lthe machine, which, for strength, and convenience of construction and-operation, is made in angular form, being narrowest at its front end. l

The frame A is supported upon the front and rear Aaxles B B1, which carry wheels B2, the front axle being pivoted to the frame by a king-bolt, b, so as to be turned in either direction while the machine is being moved from place to place.

The gearing oy which the'line-shaft is rotated is mounted in and supported by 'an annular metallic bedplate, O, which is firmly bolted to side sills or beams a, upon the frame. l

The bevel-wheel, which gears with the pinion upon the line-shaft, is alone represented, the remainder of the gearing, and the levers to which the horses are attached, not being compreheuded in the improvements herein claimed, and being liable to be differently constructed in different machines.

D represents the line-shaft, the front end of which is supported in a bearing, el, pivoted to a hanger, C, formed in a piece with or secured to the lower side of the-bed-plate. This shaft extends outward at the rear of the machine,and may be sct at any angle desired, its rear end Y being supported in a bearing within, above, or below the axle B1, as found most convenient.

In addition to being bolted to the frame, as before stated, the bed-plate C is further secured thereto by diagonal braces G2, arranged in the line of the strain exerted by the horses when operating the horse-power, they travelling in the direction of the arrows in fig. l. The braces C2 connect the bed-plate and frame rigidly 1 together, and effectually prevent the former from being loosened or displaced.

An angular frame, E, provided with a transverse bolster, El, is hinged to the rear of the machine, and may 'be turned up perpendicnlarly thereto, or set at any desired angle, its free end resting upon the ground or on a block of suitable height.

The frame E carries the tumbling-rod F, which is connected to a pivoted or flexible coupling, ll', upon the end of the line-shaft D, and has its rear end supported by the frame. The tumbling-rodis coupled to the shaft of the machinery to be driven, and, by means of the hinged frame and pivoted coupling described, can be readily adj usted to the height thereof, without altering the level of the bed-plate and frame A.

In order to maintain our horse-power ir'mly in position upon the ground, when ready for operation, and prevent it from being displaced by the movements vof the horses, the following devices are employed:

Sockets lt h1 are secured to the sides of the frame, contiguous to the front and rear axles respectively.

Braces or beams H are inserted in the sockets, having their opposite ends resting upon the ground, andy extending'in the direction oi' the'movemeut of the horses, as shown by the arrows, iig. 1.

Stakes l1,2 are irmly driven into the ground, againstl which the braces H bear whenthe strain of the horses is brought upon them.

Rods H1 are hooked to rings or staples upon the frame, and extending in opposite direction -to the braces, are connected, by chains-H2, passing around pins or rollers h thereon, to stakes h4, driven into the ground on opposite sides to the stakes h2.

By this arrangement, the four corners of thefranie are securely held, the tendency of the movements'of the horses being to push against 'the stakes hfiand pull upon stakes h*,while, by the relative positions of the braces, an effectual resistance is opposed to the displacement of the machine. l

Our improvements are free from complication, may be cheaply constructed, and when iu use, are found to accomplish, in a practical and effective manner, the objects of our invention. lVhat we cla-im as new, and desire to secure by Let-v ters Patent,is i

1. A line-shaft, extending outward at the rear of a horse-power, supported in a box or bearing below the bed-plate, and a bearing on the rear axle, substantially as described, and for the purpose of enabling the shaft' to be hung at any desired angle, as set forth.

2. A. hinged rear frame, :arryingr a tumbling-rod,

connected with the. line-shaft by a. pivoted coupling,
