` will enable others skilled in the art to which it pertains to make and use the saine, reference heilig had to the accompanying drawing, and to the letters of reference marked thereon, which form a part of this specification.

Figure l is a side view of a sled-runner having our improvement applied thereto, with a part of the securing-plate broken away. Fig. 1.

2 isa vertical transverse section, and Fig. 3 is a detached view of the anged skein.

The invention relates to thatclass ot' sleds or sleighs in which the runners are secured to axles, or to extensions of the bolsters formed into axles, in such manner that the runners can vibrate freely upon the axles, thus preventing the strain upon the parts which would otherwise be frequently produced in moving Overan irregular surface.

The invention is designed to vproduce a cheaper and Inore durable sled than has heretofore been made, and one which can be easily repaired.

1n the'drawings, A is the ruimer; B, the As these parts may be of any usual or approved construction, they need not be specifically described.

C is the post of the knee, or knee-post, as we usually prefer to call it, and is framed into the runner or secured thereto by means of an angle-iron or T-piece, or otherwise.

The skein is represented by Fig. 3. This`4l skein, in, combinationwith the knee-post C and rave B, forms the support for the axle. 1t (the skein) is made of iron, and is cast in one piece. It consists of a circular or tubular portion, C', provided at each end with flanges c c1, and upon 'the upper side with laterallyprojecting ears c2 c2. These earsare made,

by preference, of the same width as the rave B,- to which we usually secure the skein by means of rivets or small bolts.

The knee-post C'is of such size at its upper end that a semioircular seat can be cut in it to receive the lower part of the skein, and to till the entire space between the iianges c el of the lower half of'said skein. Thus when the runner A, rave B, kneepost O, and the-skein are drawn tightly together .by bolts D, `(see Fig. 1,) these parts nia-ke a very firm support for the axle. f"

.The axle :E tits accurately the inside ofthe sides, the outer faces of such portions ot' the bolts as enter the skein being rounded to tit I the skein. l

F is a circular plate or disk, `secured to the end ot' the axle. by nuts e2 e2 on the ends of Plate F is of such diameter as to confine the runner to the axle by engaging with the tlange c ofthe skein. A

1f found desirable, we propose to use a ring between the tlange cl of the skein and the shoulder formed on the axle, by rounding said axle to ft the inside of the skein. Such ring will materially' reduce the wearing of the i shoulder-of the axle, vwhich would otherwise result from the friction ofthe skein.

It will not ordinarily be found necessary to round the outer face of the bolt e, which is lof cated upon the upper side of the axle.

Having thus described our invention, what `we claim is- The tubularskein or box C, provided with the anges c cl and ears o2 e?, in combinationy with the knee-post C, having a circular seat, and fitting between the anges o c1, the axle E, plate F, bolts e e1,'tl1e runner A, rave `B, and bolts D D, all constructed and combined substantially as set forth. f 1

In testimony' that we claim the foregoing as our own We affix our signature in presence of two witnesses. f
