SLED-KNEE.

Specification of Letters Patent.

Patented Oct. 16, 1906.

Application filed February 24. 1906. Serial No. 302,813.

To all whom, it may concern:

Be it known that I, WILLARD-S. MoKU- SICK, a citizen of the United States of America, and a resident of Denmark, county of Oxford, State of Maine, have invented certain new and useful Im rovements'in Sled- Knees, of which the fol owing is a full and clear specification, reference being had to the accompanying drawings, in which Figure 1 is a detail perspective view of my improved device, and Fig. 2 is a perspective view showing its application to a sled.

The object of this invention is to provide an exceedingly strong, simple, and durable device for connecting the runner to the crossbar in such a manner that heavy loads may be borne by the cross-bars of the sled without undue strains upon the parts, as more fully hereinafter set forth.

The s ecial improvement lies in constructing the mee of a single plate of sheet iron or steel bent upon itself to form a closed substantially triangular loo The top plate of the loop fits against and sup orts the crossbar and is provided with ho es for the passage of the securing bolts or screws. The lower end of the loop is flattened, so as to bear squarely upon the upper edge of the runner.

To the accomplishment of this object and such others as may hereinafter appear the invention consists of the parts and combination of arts hereinafter fully described, and particu arly pointed out in the appended claim, reference being had to the accompanying drawings, forming a part of this specification, in which the same reference characters designate like parts throughout both views.

The top plate a extends laterally beyond the loop I) in order to give a broad support to the cross-bar c. This lateral projection of the top plate extends inward. The plate from which the knee is formed is substantially the same width throughout, and its opposite edges are provided with notches d, which when the plate is bent into shape are coincident with each other in a vertical plane. In these notches lie the vertical bolts or pins 6, which secure the cross-bar and the knee f to the runner, these bolts or pins engaging not only the notches in the edges of the knee, but also in notches in the side edges of the cross-bar. One end of the plate is welded to the underside of the top, as shown at g, and inclines upwardly and inwardly to form a stiff brace.

What I claim, and desire to secure by Letters Patent, is y In combination with a sled-runner and a cross-bar, a kneestructure consisting of a plate bent into a substantially triangular shape and having a top plate extended laterally and adapted to support the cross-bar and a bottom plate adapted to rest on the runner and an upwardly and inwardly inclined brace, the opposite edges of the top plate and the bottom plate being coincidently notched, and pins or bolts fastened in the runner and en aging said notches.

In testimony w ereof I hereunto afiix my signature, in the presence of two witnesses, this 3d day of January, 1906.

WILLARD S. McKUSIOK.
