SLEIGH.

SPECIFICATION forming part of Letters Patent No. 558,556, dated April 21, 1896.

Application tiled October 4,1895. Serial No. 564,590. (No model.)

T0 all whom, it may concern:

Be it known that LWILLIAM L. HAAG, a citizen of the United States, and a resident of Lansing, in the county of Ingham and State of Michigan, have invented new and useful Improvements in Sleighs; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

My invention is related to that class of sleighs termed bobesleighs or carriagerunners.7 Its object is to connect the bolster or carriage-axle to the knee of the sleigh by a clamp solidly attached to the bolster or axle and movable on the knee instead of a clamp which is a part of the knee and movable on the axle.

It consists of a knee so constructed that it forms a semicircular rest for the bolster,which has a clamp solidly attached to it, through which the curved portion of the knee passes, and in which it moves forward or backward as the runner is thrown up or down in passing over the inequalities of the road, and in the peculiar construction and arrangement of the several parts, as hereinafter more particularly set forth and claimed.

Figure 1 is a perspective view of my sleighknee or carriage-runner. Fig. 2 is a section through the upper part of the knee and the bolster on the line a; :c in Fig. 1. Fig. 3 is a section through the support of the outer end of the bolster on the line fy g/ in Fig. l. Fig. 4t is a perspective view of the semicylindrical block attached to the under side of the bolster. Fig. 5 is a perspective view of the retaining-block on the under side of the semicircular top of the knee, showing the recess for the knee and for the block attached to the bolster. Fig. 6 is a plan view of the retaining-block, showing the block on the under side of the bolster resting on its recess.

In the drawings, A represents the runner provided with the usual shoe a.

A is a brace or rave connected to the front end of the runner and extending back to the front leg of the knee, to which it is securely riveted or bolted.

B B are the front and back legs of the knees some distance apart on the runners, inclined toward each other, so as to be but a short distance apart at the top. These legs are prolonged in the feet b b, provided with iianges to embrace the runner, and are securely fastened to the runner by bolts passing through the feet b Z9 and the runner and shoe.

B is a bar of the same width as the knee, fastened at its central point to the runner, at the middle point between two feet of the knee, having its two ends turned upward as braces to the two legs B B of the knee to which they are firmly riveted. This construction makes the knee strong enough to carry a heavy burden and to resist great strain either forward or backward.

The upper or central part of the knee is bent downward between the two legs in a semicircle to form the curve B2, on which the axle or bolster C rocks.

D is a semicylindrical block fastened to the under side of the axle or bolster C near its outer end. The axle or bolster is of the ordinary construction, except the block D ,which takes the place of the usual bearing for the hub. The upper or flat face of the block D is in contact with the axle and the rounded or lower face bearing on the curved part B2 of the knee.

Recesses d d d d are cut in the block D at each of its four corners,forming the shoulders d d d d' and d? d2 cpd?. These shoulders rest against the bolts e on the clips E, which pass through the recesses d and the perforations f5 in the retaining -block under the curved top of the knees.

The arms or projections di cl3 on the block D are flat on their under side with square ends and rest on a flat shoulder at the end of the recess f in the retaining-block F and against the wall or end of the recess.

The arms or projections d4 d4 do not entirely cover the sides of the curved recess f, but leave an opening between the bearingblock D and the retaining-block F for the reception of the curved top B2 of the knee, which supports the axle or bolster.

F is the retaining-block under the curved top B2 of the knee attached to the axle or bolster by the bolts e at the ends of the clips E,passing through the perforationsf. A con- IOO cave recess f is formed in the upper side of the block, having the same curvature as the under side of the semicircular top of the knee. At the ends of this recess a curved ledge or shoulder f2 is cut, having the same curvature as the under side of the bearing-block D, which rests upon it, leaving a space or opening between the under side of the bearingbloek and the concave recess f of the proper size and form to receive the curved top B2 of the knee. The dotted outline of the upper part of the knee in Fig. 2 of the drawings shows the extent of the play of the knee on the axle or bolster.

Another shoulder f3 is cut above the shoulder f2 in both ends of the recess, having a iiat straight surface and side for reception of the arm cl3 cl3 of the bearing-block D. The end walls of the recess f, engaging with the ends of the bearing-block D, prevent any lateral play of the knee on the axle or bolster.

Gis a semieylindrical block or saddle on the top of the axle for the purpose of obtaining a longer bearing for the clips E, which straddle the block and axle, and the ends pass down through the recesses d CZ on the bearing-block and the perforations]c5 through the block F, where they are secured by screws and nuts. lt is evident that this block G may be entirely omitted if the bolster is large enough to afford suflieient bearing for the clips.

H I-I are two braces or arms projecting outward from the lower part of the front and back legs of the knee and inclining toward each other at about the same inclination as the inclination of the legs of the knees. The

downwardly-projecting curved plate 7L and the flat plate 7L above the curved plate h are firmly attached to the outer upper ends of the arms H H in a horizontal position by bolts or rivets. These two plates form a semitubular socket, having its axis in a straight line with the axis of the bolster or axle of the sleigh. The outer end of the axle or bolster C is rounded to engage with this socket, and is provided with the collar C to prevent end play of the socket on the axle. These braces or arms thus connected with the outer end of the axle or bolster prevent any lateral motion of the runner either inwardly or outwardly, while leaving it free to work backward or forward as it passes over the inequalities of the road.

That I claim as my invention is- 1. The combination of a sleigh-knee, having a downwardly-curved upper end, with a block through which the downwardly-curved upper end of the knee passes firmly attached to the bolster, and the bolster above the knee, all substantially as described.

2. The combination of the downwardlycurved upper portion B2, of the knee, with the retaining-block E, through which the downwardly-curved portion of the knee passes irmly attached to the bolster, and the bolster above the knee, all substantially as described.

3. The combination of the knee having a curved top which rocks on the bolster, the bolster convex on its lower side to rest on the curved top of the knee, and the retainingblock through which the curved top of the knee passes iirnily attached to the bolster, all substantially as described.

4E. The combination of the knee having a curved upper end with a bolster resting on the curved upper end of the knee, a retaining-block under the curved part of the knee iirmly attached to the bolster, the arms extending froin the knee supporting the socket, and the socket for the reception of the end of the bolster, all substantially as described.
