SLED-KNEE.

Patented Oct. 13, 1908.

Application filed July 30, 1904. Serial No. 218,878.

T 0 all whom it may concern:

Be it known that I, ROBERT SLEETH WELLS, a citizen of the United States, residing at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Sled-Knees, of which the following is a specification.

My invention, While adapted to use on any kind of sleighs, is preferably designed for use in that kind of sleigh known as a bob sled for drawing loads, and the object of my invention is to produce a sled knee of great strength and durability, and that may be cheaply constructed.

Referring to the drawings, Figure 1 is a view of a sled in which my knee is employed. Fig. 2 is a plan view of the preferred construction looking from the top down. Fig. 3 is a similar view from the bottom looking upward. Fig. 4 is a view from the outside of the sled on a line parallel with the beam. Fig. 6 is a similar view from the inside, and Fig. 5 a view from the rear. Figs. 2 and 3 show modified forms of the foot.

Similar letters refer to similar parts throughout the different views.

My sled knee is preferably formed from a single piece of stamped metal, but may be made of cast or malleable metal without departing from the spirit of my invention. It is composed of an exterior plate L having flanges M bent at substantially right angles to the body L except that near the upper part of the flanges M, namely at the point E, they are bent inward to form ledges, as shown in Figs. 2 and 6, for the beam D of the sled to rest upon. At the lower extremity, the side flanges are preferably bent outward as at F, and secured by bolts to the runners as shown in Fig. 1, a bolt or rivet also passing through the piece G at S to lend additional strength. If desired, however, for different styles of runners, the piece G may be either dispensed with entirely, as shown in Fig. 3, or bent outward as in Fig. 2. The flanges M are preferably widened at the top, as shown in Fig. 5, to give additional stiffness.

The flanges M by their peculiar construo tion with the ledges E not only serve to support the body of the sled and carry the load, but also act as braces against the effects of side-wise slipping of the sled runner, and by constructing the device wholly as shown in the drawings a knee is produced of great strength, beauty and durability which is nevertheless very economical in construc tion.

I claim as my invention 1. The combination in a sled knee of a metallic body and stiffening flanges, substantially at right angles thereto, said flanges being offset adjacent their upper ends to form a beam supporting ledge, substantially as described.

2. The combination in a sled knee of a metallic body and stiffening flanges, substantially at right angles thereto having portions thereof offset to form a beam supporting ledge and supporting feet, substantially as.

described.

3. The combination in a sled knee of a metallic body, stiffening flanges, substantially at right angles thereto, an offset portion forming a beam supporting ledge having suporting feet, and means for securing said lfnee to a sled runner or beam, substantially as described.

4. A sled knee formed of an integral structure comprising an upright body portion and stiffening flanges extending longitudinally thereof at substantially right angles, the flanges having offset portions adjacent their pplper ends constituting a beam supporting 5 A sled knee formed of an integral structure comprising an upright body portion and oppositely disposed stiffening flanges extending longitudinally of the edges thereof at substantially right angles thereto, the flanges having offset portions adjacent their upper ends constituting a beam supporting ledge, and offset portions at their lower ends constituting supporting feet.

6. A sled knee formed of an integral structure comprising an upright body portion and oppositely disposed stifiening flanges extending longitudinally of the edges thereof at substantially right angles thereto, the flanges being relatively wide at their upper ends and having oflset portions at said upper ends constituting a beam supporting ledge, and also having offset portions adjacent their lower ends constituting supporting feet adapted to be secured to the runner.

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

ROBERT SLEETH WELLS.
