HORSE-RAKE.

SPECIFICATION forming part of Letters Patent No. 305,649, dated September 23, 18841.

Application filed October 27, 1883. (N0 model.) Patented in Canada December 11, 1883, No. 18,275.

To all whom it may concern.-

Be it known that I, WILLIAM SANDFIELD WILSON, of the village of Ayr, in the county of Waterloo, in the Province of Ontario, Canada, mechanic, have invented certain new and useful Improvements in Horse-Rakes; and I do hereby declare that the following is a full, clear, and exact description of the same.

. The invention relates to that class of horserakes in which the carrying wheels revolve freely on the axle, and to which axle the raketeeth are attached.

The object of the invention is to devise a simple and effectual friction dumping device, and to otherwise construct the machine 'so as to make it simple and effectual in its operation; and it consists, essentially, in loosely at taching to the end of the axle a flanged clamp adapted and arranged, in connection with a cap, to. clamp the inner and outer surfaces of a pulley-shaped hub formed on the carryingwheel, the said friction-clamp being operated by a rod journaled on the axle and operated by the dumping lever, as hereinafter more particularly explained. I

The peculiar plan of bracing the thills also forms a feature in my invention, as does also a plan for trussing the wooden axle, and other features which will be hereinafter more particularly explained.

Figure 1 is a perspective rear view of my improved horse-rake. Fig. 2 is a perspective view on an enlarged scale, showing in detail the end of the axle with the friction-clamp and parts connected. Fig. 3 is a perspective view showing the connection between the chill-frame and axle. Fig. l is a side elevation showing the seat attached to the axle. Fig. 5 is a perspective detail view showing the manner of bracing the thills, with their connection to the axle. Fig. 6 is a perspective detail view of the center casting for the bracing-rods of the thills, the dumping-lever, and whiffletree. Fig. 7 is a rear elevation of the axle, showing the truss-rod.

In the drawings, A are the carrying-wheels, and B the wooden axle. Each end of this axle is capped by a bracket, 0, which forms a protection for the end of the axle, and has an arm, D, extending from it to carry the rider-bar E. .This bracket 0 is provided with a projection,

off. Each wheel A has an inwardly-project- 6o ing hub, a, formed on it in what may be termed a pulley shape-that is to say, a rim having an inner and outer surface. This rinror pulley-shaped hub a forms a bearing-surface for the friction-clamp, which is formed in the 6 5 following manner: A flange, H, extends outwardly from the plate- I, and is adapted to fit the outer surface of the pulley-shaped hub (1 J is another flange attached to the plate I, on the side opposite to the flange H, and adapted to fit the inner surface of the pulleyshaped hub a. The plate I has an oblong hole made in it to fit over the boss F, and is sup ported and operated by the rod L, as hereinafter described. v

K is a friction-cap adapted to fit the outer surface of the pulleyshaped hub a; This friction-cap has an eye, b, through which the hooked end d of the rod L passes. This rod L has bearings near the center of the axle B, and in a hole made in the extension-piece M, which is attached to or forms part of the plate I. WVhen the wheel A is put in position, its pulley-shaped hub a passes between the cap K and flange J, while the other flange, H, is located nearly against the outer surface of the pulleyshaped hub a. Owing to the positions of the flanges H and J and the frictioncap K, and also the fact that the rod L and hook 01 support the plates I and K, respectively, the said flanges and cap are caused to approach each other, thus clamping the hub a when the rod L is rolled in its bearings. The motion of course need be but very slight, being merely sufficient to cause the clamps to 5 clasp or release the hub. The hole made through the extension-piece M of the plate I is slightly larger than the rod L, a set-screw, d, being employed for the purpose of reducing the size of thehole and forming a fulcrum- 109 point for the hooked rod L. The position of the fulcrum-point is thereby adjustable. I.

I .have spoken of only one rod, and have resimultaneously, a crank, e, is formed on the inner end of each rod. These cranks are connected to the horizontal lever f, which is pivoted or fulcrumed on the quadrant-brack et 9. The end of the horizontal lever f is connected by a chain, h, with a foot-lever, i, which is pivoted on the thill-framc, as indicated. By pressing on the foot-lever t the lever f acts against the cranks e, causing the rods L to rock in their bearings, and, as the'outer ends of these rods are connected, as described, to the friction-clamps, these latter are caused to clamp the hub a. It will of course be understood that the hooks d, formed upon the outer ends of the rods L, are bent in a reverse direction to each other, so that both clamps work simultaneously, notwithstanding the fact that the rod leading to one end of the axle rolls in an opposite direction to the rod leading to the other end of the axle.

N is atruss-rod extending from end to end of the axle B, immediately below its bottom edge, so as to form a support for the teeth 0,

' which are attached to the axle B, and extend plate I is made oblong, so that said plate may projection 0 onthe plate 0 by the nut n onmove when the clamps are being operated.

0 is a washer of sufficient size to prevent its passing through the slot in the plate I, and is held in bearing contact with the face of the the truss-rod N, on which the said washer is mounted. By this construction the space he tween the said washer and the plate 0 is greater than the thickness of the plateI, which is loosely confined between the two in such a manner as not to interfere with its adj ustabilit-y, but still prevent its lateral displacement.

In order to relieve the horse as much as possible from the weight of the driver, I arthe rake is being dumped. A'brace-irod, s,

having one end rigidly secured to the thills and the other to the support S, serves to stay the seat. This construction allows of the axle being rocked and the ,rake. dumped without changing the relative position. of the seat. In order to permit the axle B to rock in this manner, it is necessary that the thill-irons 1? should be set as shown in Figs. 3 and 5. In order to relieve these thill-irons P of the shock causedby the axle striking against them, and also to cause the said axle to recover itself quickly whiffletree T and the hand dumping-lever U, I provide a casting, V, which is shaped substantially as shown in Fig. 6. Y What I claim asmy invention is 1. In a horse-rake, the combination of the axle provided with spindles upon which the wheels revolve freely, a pulley-shaped hub formed on the inside of each wheel, a pendent plate movably connected to the axle and looselysurrounding the spindle, and having, two friction-flanges opposite to each other, one flange adapted to fit the outer surface of the pulleyhub and the other flange the inner surface thereof, and mechanism adapted to actuate the plate so as to press its flanges against the pulley-shaped hub, and thereby form a friction-connection between the wheel and axle, as and for the purpose herein specified.

2. In a horse-rake, the combination of the axle, the spindles, the wheels revolving freely thereon, the rake-teeth connected to said axle, a plate movably attached to the axle, and having two projecting friction-flanges formed on it to fit against the pulley-shaped hub of the wheel, as specified, and a curved cap adapted to fit the outer surface of the pulleyshaped hub, and located immediately over the flange fitting against the inner surface of the hub, and a crank-rod journaled in the plate and having its crank end attached to the cap in such a manner that by rocking the rod the cap and flange are caused to press against the IIO hub, substantially as and for the purpose 4. In a horse-rake, the combination of the wooden axle, the spindles secured thereto, the wheels revolving freely on said spindles, the rake-teeth attached to said axle, an iron bracket .fixed to each end of the axle, and provided with a boss forming part of the wheel-spindle, the flanged clamp supported by said boss, and

an arm extending from said bracket to support the end of the rider-bar, substantially as and for the purpose specified.

5. In a horse-rake, the friction dumping device consisting of a movable flanged clamp and a cap arranged to clamp the inner and outer surfaces of the pulley-shaped hub of the wheel, in combination with a rod journaled on the axle, and having on its inner end a crank connected to the dumping-lever, and on its outer end a hook upon which the clampingcap is suspended, substantially as and for the purpose specified.

6. In a horse-rake, the combination of the wooden axle, the spindles fixed thereto, the wheels revolving freely on said spindles, the rake-teeth secured to the axle, and a truss-rod extending from end to end of the axle on its bottom side and supporting the rake-teeth,
