THEODGR J. STRUPP, 0F ELKTON, SOUTH DAKOTA.
SLED-RUNNER.
Application filed November 11, 1911.
To all whom it may concern:
Be it known that I, THEODOR J. STRUPP, of Elkton, Brookings county, South Dakota, have invented certain new and useful Improvements in Sled-Runners, of which the following is a specification.
The object of my invention is to provide a sled runner of simple, economical construction and one which will be light and durable.
A further object is to provide a runner having a shoe which can be easily and quickly applied to the runner or removed for substitution or repairs.
The invention consists generally in various constructions and combinations, all as hereinafter described. and particularly pointed out in the claim.
In the accompanying drawings forming part of this specification, Figure 1 is a side elevation of a sled runner embodying my invention, Fig. 2 is a rear View, Fig. 3 is a top view.
In the drawing, 2 represents the metal pipe or tubing which is bent upwardly in a suitable shape for a sled runner. This tubing is preferably oval shaped in cross section, with the sides flattened, the vertical axis being the longer, as shown in Fig. 2. In the forward. end of the tubing 2 is inserted and secured by suitable means a metal plug 3, said plug having a slot 4 which is adapted to receive the roller or cross bar of the sled pole. To the bottom of the tubing 2 is secured by bolts 5 or other suitable means a metal shoe 6, the upper surface of which is concave and adapted to fit the convex surface of the tubing 2. The forward end of the shoe is turned upwardly to conform to the curvature of the runner and fits snugly against the rounded under surface of the runner throughout the length of the shoe. 1 also prefer, as shown in Fig. 3, to make the shoe with a comparatively wide tread, tapering gradually from the bottom to the top of the shoe. The concave upper surface of the shoe provides for a broad bearing surface for the runner with a minimum of width, thereby offering less resistance to the passage of the runner and shoe through the snow, while the broad tread of Specification of Letters Patent.
Patented Jan. 7,1913.
Serial No. 659,738.
the shoe affords additional support for the runner under a heavy load.
On the top of the sled runner I secure by bolts or other suitable means a knee 7. Said knee is constructed preferably of one piece of iron or other suitable material, is con cave, and adapted to fit the convex surface of the tubing 2. The legs of the knee extend down on each side of the runner and serve to brace and stiffenit and at the same time a substantial support is provided for the knee and its load. The apex 8 of the knee is convex and is adapted to support a metal plate 9, which is secured to the knee 7 by means of a bolt 10 which. passes through the downwardly projecting flange 11. The plate 9 has a concave groove 1.2 so that it is adapted to fit over and rock upon the apex 8 of the knee 7, the plate being designed to support the cross bar of the sled which is bolted to it.
In various ways the details of construction may be modified without departing from the spirit of my invention.
I claim as my invention A sled runner composed of a flattened tube having upper and lower rounded surfaces and side surfaces parallel substantially with one another, a shoe having a concave upper surface and an upwardly turned forward end and adapted to fit snugly against the under surface of said runner, said shoe having a comparatively broad base that is wider than the minor diameter of said tube, bolts passing vertically through said shoe and said runner and securing them together, the flattened form of said runner allowing the use of larger tubing without increasing the width of the shoe or projecting the tubing beyond. the sides of the shoe, whereby there is less obstruction to the passage of the runner through the snow and a greater elevation is provided for the knee supporting surface of the runner.
In witness whereof, I have hereunto set my hand this 2nd day of Nov. 1911.
THEODOR J. STRUPP.
