SLED.

SPECIFICATION forming part of Letters Patent No. 364,046, dated May 31,1887.

Application filed March 3l, 1887. Serial No..233,190. (Model.) 4

To LZZ whom t may concern:

Be it known that l, VILLIAM SCHAU, of Newaygo, in the count-y of N ewaygo and State ot' Michigan, have invented certain new and useful Improvements in Sleds, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying dra\vings,which form part of this specification.

My invention relates to an improvement in sleds; and it consists in, rst, the combination of the runner, the knees secured rigidly thereto, the cross beam which connects the knees together, the braces which are secured to the under side ofthe cross-beam, and the rods which are connected both to the cross-beam and the runners, and which pass down through the knees and the braces; second, the arrangement and combination of parts, which will be more fully described hereinafter.

Figurel is a side elevation of asled to which my invention is applied. Fig. 2 is a rear elevation of the same. Fig. 3 is a plan View. Fig. 4 is a vertical section taken down through the cross-bar.

A represents the runners, and B the knees secured rigidly to the runners, and have openings through their tops for the rods C, connected to the under side'of the cross-beam D and the top of the ruimer, to pass through; These rods are held in place by the runners and cross-beams, their lower ends beingv held in sockets in the tops of the runners and their upper ends in sockets in the under side of the cross-beams. two shoulders, G, which limitthe distance that the brace and the crossfbeam shall move The braces H, which are secured at both of their upper ends to the underside of the cross-beam D by means of the bolts I, eX- tend downward through the knees and are provided with openings at their lower ends for the rod C to pass through. The braces are loosely connected to the under side of the crossbar by the bolts I, extend at right angles to the knees, and have a limitedvertical movement upon the rods C, which is limited by the shoulders G. As the rod C is loosely connected at its ends to both the runner and the cross- These knees are These rods C are provided withbar, andas the braces H are loosely connected to the under side of the cross-bar and to the rod C, a flexible connection is formed between the runners and the cross-bar, so that one runner can have a more or less independent movement of the other. These runners are connected together at their front ends by the crossbar J, to which the tongue is secured, and eX- tending from this cross-bar back to the front edge of the cross-beam D are the brace-rods L, which are loosely connected at both ends. The runners always move together inthe same direction, but, being loosely connected together to the cross-beam, each one can twist and give, when passing over obstructions and inequalities in the road, independently ofthe other.

The bolster N is pivoted upon the top of the cross-beam D by means of the king-bolt O. Secured to the rear side of this bolster N is the reach P, which is also secured to the top of the circle R. This circle R is made from a ilat piece of iron, which is turned up upon edge and secured to the bolster by means of the braces S, which extend up over the top of the bolster, as shown. Upon the top of the crossbeam Dare secured the two bearing-plates T, upon which the lower edge ofthe circle bears, and which plates protect the beam D from wear. This circle, being rigidly secured both to the reach and the bolster, keeps the bolster in a horizontal position with the sled, which makes the sled less liable to tip thanany now in use. This circle, being made of tire-iron and bent the same as fora tire, is brought edgewise under the bolster, as shown. At that point where the reach P is secured to the circle the iron is bent down so as to it the'under side of the reach and yet leave the lower portion of the circle perfectly dat. By means of devices here shown and-described `for connecting the cross-beam to the runners three bearings are formed upon each runner, so as to lessen the liability to break the shoe, andthe bearings are so made thatdescribed my invention, I

1. The combination of the runner, the knees secured rigidly thereto, the beains, the rods which connect the beams andrunners together, and the brace which is connected to the under side of the beam, extends at an angle to the knee, and has the connecting rod to pass through its lower end, substantially as shown.

2. The combination of the runners, the knees rigidly secured thereto, the braces extending at right angles to the knees, the crossbeam, the rods which connect the cross-bearn and the runners together, and which pass through both the braces and the knees, connecting-rod J, which unites the front ends of the runners together, and the brace-rods L, substantially as described.

3. The combination ofthe cross-beam l), the bolster N pvoted thereon, the reach P, the circle R, the braces S, which secure the bol-I ster and the circle together, and the bearingplates T, placed upon the top ofthe cross-beam, the circle being placed upon edge and secured rigidly both to the bolster and the reach, substantially as set forth.

In testimony whereof I ax my signature in 25 presence of two witnesses.

WILLIAM SCHAU.
