IMPROVEMENT IN HOR$E-PQWERS.

Specification forming part of Letters Patent No. 1 15,4973, dated December 9, 1873; application filcd November 1, 1 73.

To all whom it may concern Be it known that I, DANIEL WoonnURY, of the city of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Horse-Powers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same.

My improvement relates to mounted horse powers, and, in general principle, is similar to other patents heretofore issued to me. The invention consists in the construction and arrangement of parts as hereinafter described.

In the drawings, Figure 1 is a plan. Fig. 2 is an elevation. Figs. 3 to 15, inclusive, are detail views.

A is the main frame, attached to an axle or bolster, B, which may either be mounted on wheels 0 G, as shown in Fig. 2, or on a sled, O, as shown in Fig. 13. The main frame is at tached well forward on the axle, so as to bring the preponderance of weight in front, and it is braced and stayed by straps a a, bolted on the under side of the mainframe, and encircling the body of the axle, as shown in Figs. 2 and 11. D is the traveling frame, pivoted at b b to the under side of the main frame, or to arms thereof, just in front of the axle, instead of to the cross-piece of the main frame back of the axle, as has heretofore been done. The pivotal point is thus so far forward that the axle can extend out full length for the attachment of the wheels, and the leveling-frame can be made much shorter than usual, not extending much.

forward of the machine itself, thus allowing the tumbling-rod to pass freely over it, instead of under it, as formerly. The leveling-frame is used as the support for the machine in trans portation, being raised for that purpose, and resting on front wheels. E is the rim, and F the bull-wheel or main driving-gear, of the machine, which are cast in one piece. These parts revolve upon the .main frame, and the bull-wheel gives motion to two pinions, l 1, on an inclined shaft, 0, Fig. 2, which extends One of these pinions wheel, by which the same motion is imparted to shaft 0. A stationary pinion, 3, is located at the rear of the machine, under the pinion 1 and beneath the bull-wheel, for the purpose of balancing the gears and preserving the engagement. The teeth on the upper side of the bull-wheel are longer than those on the under side, so as to allow the proper play of the bullwhe'el and prevent any disengagement under long wear. The journals of the pinion 3 rest'in a box, 0, Fig. 11, that is supported by a basebar, f, at the bottom. A clamp, g, rests against the rear of the box. By this means the said box may be adjusted higher or lower, and clamped at any desired position, and the parts f 9 being made of wood, they will break under heavy strain, and thereby prevent injury to the gearing. This obviates difficulty from one cog striking upon another. G, Figs. 1 and 5, is a covering ring or cap, which fits over the bull-wheel. H H, Figs. 1 and 5, are two guide blocks or slides, which rest upon the ends of the arm 2' of the main frame. Each has a fork, is, which embraces the inner edge of the bullwheel. They are made adjustable lengthwise by means of keys ll, which are driven into sockets in the bar 17,- and said blocks are fixed at any position byscrews and slots m m on top. Each block H has a lip, 10 which laps down over the arm 1 on the side reverse to the motion of the bull-wheel, the arrangement being such as to allow the arm i to extend all the way out.

The object of this arrangement is to keep the bull-wheel in place, both vertically and laterally, against the strain which occurs in operation, or if the cogs slip. The blocks can be tightened to any. desired degree by driving the keys, and the fork embracing the bullwheel prevents any escape of the latter, although allowing it a free revolving motion.

I is one of the sweeps by which the power is applied. Four or five are generally used. K is a brace-arm, pivoted to the sweep at a, and resting at the inner end against a bearing, 0, secured to the rim of the bull-wheel. The end of the brace-arm is made angular or rounded, to fit the angular or rounded space between the bearing and the rim, and it is provided with an iron shoe to prevent injury and insure proper strength. A shank, p, rests in a socket of the brace-arm, having a longitudinal play, Fig. 6, and the end of the shank is provided with a hook, q,

purpose of a fulcrum.

that engages with an eye, 1*, on the under side of the bearing 0. This arrangement allows the engaging of the hook and eye, and the proper play of the shank p, in straightening the brace-arm back to engage with the sweep. When the pressure of the sweep is applied against the brace-arm, the strainis all expended on its end resting against the bearing, and none comes on the hook and eye, the latter being employed only for connecting and holding the parts in place, and holding it in place when the strain is reversed, or the horses hold back. J L are outrigs or stake-bars, attached to the sides of the machine and staked to the ground, to resist the strain and keep the machine in place. Their inner ends have sockets, which fit upon bearings s s on the front and rear of the main frame. Their outer ends meet at an angle, and are secured together by a socket, t, of the part L, which fits upon a horn, a, of the bar J. The outer end of the bar J has a staking-socket, '27. M is a standard, and N a share or stay-bar. The standard is attached at the bottom to a cross-piece of the leveling-frame, and its top extends up through a slotted plate, 20, which rests on top of the supporting-bars 00 a; of the main frame. The share is made to rest on the ground, and passes up through a similar plate, 2. The standard and share are both provided with a series of holes, a a, through which pass pins resting under the plates to hold up the main frame. The standard is employed for sustaining the main frame while the leveling-frame rests upon the ground in operation. The share is employed for sustaining the main frame while the leveling-frame is being elevated for the purposes of transportation, or to let the main frame down upon the leveling-frame. In such case the share is fixed in position, and the standard released, and the leveling-frame can then be raised. WVhen a sled is used, the share may, in some instances, rest upon the front cross-bar of the sled, and

hold up the leveling-frame at such a height as not to interfere with the tongue of the sled. O is a reach, consisting of a straight bar with lugs b N, and a cross-piece, 0 at the rear. In Fig. 3 it is shown attached to the end of the leveling-frame by means of a pin, (1 with the cross-piece 0 resting on top, and serving the In this condition the, reach serves to attach the front end of the ma chine to the front or rear axle of a common wagon, or to the wagon itself, for transportation, in such case bringing the leveling-frame up sufficiently to run clear ofobstructions, but allow the gears to run low. hen the machine is mounted on a sled, the reach may be reversed, as in Fig. 4, and stand upward, forming a foot-board. The driver sits upon a seat, 1, attached to a cross-bar, f which is sustained by standards g which fit on the bearings 0 0. The crossbar f, in connection with another cross -bar, 11 on the rear of the machine, serves as the support for the levers when detached for transportation. The reach may also be used beneath the machine, being screwed or otherwise secured to the under side of the axle, its rear end projecting back, and the cross-piece 0 resting on the ground, while the front end projects forward, and is connected to the hook 7L2 of the share, the latter being drawn up tight and secured by the pin to the plate 2. The reach, in this case, serves to give a broader bearing beneath the machine, and a support back ofthe axle, to obviate tipping, as the power is applied on different sides of the machine.

Q, Figs. 1 and 12, is afriction-brake, hingedor otherwise attached at i to the main frame, in position to receive the foot of the operator. It has a curved bearing, k which extends downward at right angles, or nearly so, and rests against the inner periphery of the rim of the spur-gear 2, or against any other part of said gear. A spring, 8 rests under said brake, so as to remove the contact when it is not in use. By pressing upon the long arm of the brake, the operator can check the motion at any time. It R are the boxes in which the shaft 0 runs. They are made convex or rounding on the four sides, so as to adapt themselves to the position of the shaft at all times, and prevent binding or strain,

which would occur if they were straight-sided and fitted closely in place. The cap P, which fits over the rear box, rests loosely, so as not to bind the box. The outer ends are provided with cylindrical projections m Fig. 9, which fit into corresponding sockets of the pinions 1 1. B y this means the boxes are made longer, so that an equal bearing comes on both ends, and undue binding and strain are avoided, and the shaft can be made stronger. This also insures more even wear on the ends of the boxes. The boxes are made in two parts, a 0 the first, preferably, of metal and babbitted, and the last, preferably, of wood, fittin into the other, as shown in Fig. 10, which is an end view. The opening in the part a is large enough for the shaft to be inserted laterally, and the part 0 closes the space around the shaft. The part 02 receives the great wear, while the part 0 allows the pinion to be taken off or replaced, and facilitates the keying of the pinion and the removing the same for repairs. It also .makes the box stronger. At the inner end the parts may be secured together by a vertical pin. 12 is an oilgroove. S is a Windlass, mounted in bearings on top of the main frame, and employed for drawing up loads of any kind. A shifting-clutch may be connected with its shaft and arranged to shift the motion by reversing a lever or otherwise. At the outer end of the shaft is a spur-gear, 4, which engages with the bull-wheel, and transfers motion to the windlass. The clutch may be so arranged as to allow the gear 4 to run loose when not desired to give motion to the windlass. A is a hanger hinged on the under side of the main frame, supporting a pulley, m The winding rope from the Windlass passes down around the pulley, and thence extends to the load to he moved. To a bail at the lower end of the hanger is attached a stay-cord, o staked to the ground. This hanger and pulley can be turned up against the frame to be out of the way in transportation, and, being hinged, it will yield so as to prevent twist upon the frame. T is one of the couplings of the tumbling-rod. The shafts have the ordinary forks g (1 that of one part being made of less diameter than the other. They are secured by the ordinary cross-pins 1 1' and an encircling ring or shield, 2 surrounds the whole. One end of each pin fits in a socket bored through one side of the ring, and partially through the other side, and when in place the end of the pin resting in the open end of the socket is covered by a cap, t which is fastened in place in any desired manner.

The arrangement above described is a convenient and cheap means of securing the pins, and is also such that the ends of the forks of the rods cannot wear together, which is a great difliculty in the old style of coupling. The ends always remain clear of each other under all degrees of wear.

U is a jack for transferring motion from the power.v It consists of a frame, V, staked to the ground at a distance beyond the path of the horses. In this is pivoted, at j, a block, \V, and to this block is pivoted, by a bolt and nut, a a standard, X. The pivots of the parts W and X are at right angles to each other. The tu mblin g-rod passes through suitable bearings in the standard X, and has a bevel-gear, 6, upon its outer end. Into this gear meshes a bevel-pinion, 5, on a shaft, 0 which extends vertically through bearings of the standard. On the upper end of the shaft is a band-pulley, 3 Beneath the pulley is a ring, Z, which turns freely upon a suitable seat at the upper end of the standard. The ring is held in any given position by a clamp, 10 tightened by a set-screw. On one side of the, ring is afixed bearing, J which holds a loose pulley, a. The band, as it comes onto the main pulley Y, passes over the small pulley (1. which acts as a guide to keep the band in place, and the small pulley can be turned to any position by the -adjustment of the ring-Z, as before described, thereby allowing the band to run in any direction. is a segment-guide, pivoted at the lower end to a plate, b that has a series of holes, as shown in Fig. 2. The upper end of the segment passes through a slot in the standard X, and the latter is held to it at any position by a set-screw, e

By the arrangement above described, the standard X, with its pulleys Y a, can be turned to any incline, either upon the joints 7 or 10 and these two adjustments are at right angles to each other. The position is fixed at any adjustment by the nut a and set-screw c, as before described. The plate b allows the adjustment on the pivot 20 to take place by changing the pivot of the end of the segment to different holes in the said plate.

When the machine is mounted on a sled, I

make the front cross-piece of the sled removable from its sockets, to allow the tumblingrod to pass down in the proper direction.

Having thus described my invention, what I claim as new is- 1. In a mounted horse-power, such as shown and described, the leveling-frame D, Windlass S, outrigs J L, slides H H, and brake Q, combined with the main frame A, to operate in the manner and for the purpose specified.
