SLED.

SPECIFICATION forming part of Letters Patent No. 311,126, dated February 3, 1885.

Application filed September 10, 1884. (No model.)

To all whom it may concern:

Be it known that I, PATRICK H. GUMMINs, of Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Sleds; and I do hereby declare that the following is a full, clear, and exact description thereof. reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

The object I have in view is to provide means whereby the shoes of a sled may be easily, quickly, and securely attached to the runner; and to these ends my invention consists, first, in constructing the shoes either circular or semicircular in cross section, and the bottom of the runner with either convexity or concavity in cross-section, in which or upon which the shoes are laid; and, secondly, in turning theshoes at both ends so as to embrace the rear and forward ends of the runners, all as will be more fully understood from the following description, when taken in connection with the annexed drawings, in which Figure l is a perspective of the sled, and Figs. 2 and 3 crosssections of the runner and shoe.

Similar letters of reference indicate corresponding parts.

A A represent the runners; B B, the supports; 0 O, the raves; D D, the cross-bars;

E E, the shoes, and a a bolts through the runners.

The construction of the sled is or maybe that in general use, and hence I need not enter into the details thereof. The shoes are round rod iron or steel of suitable diameter, and are jsufficiently long to admit of their being turned over the rear and front ends of the runner, as seen in Fig. 1. Each runner is formed along its bottom with a semicircular groove, in which the shoes are placed. These grooves should be about one-half the diameter of the shoes, thus exposing a sufficient surface of the latter to protect the former from wear. It will be observed that the rear top portion of the runners are also grooved out to receive the ends of the shoes, which are bent forward and forced down in said grooves.

grooves are made in the forward ends of the runners and raves, where they unite, and the shoes are likewise bent rearward therein, thus effectually bracing and clamping said parts Similar l together, while at the same time dispensing with the necessity of screws or bolts to fasten the shoes to the runners.

It is obvious that instead of employing rodiron for shoes and grooving the runner, as described, I may just reverse this construction by having the runner convex on this under side, and the upper portion of the shoes concave, as seen in Fig. 3. -In either event the effect will be the same in dispensing with other means of fastening for the shoes. The front and'rear ends of the shoe E are turned over the runner, and either embedded there in, as in the case where the round rods are used, or made to hug the convex surface in the case where concave shoes are used. By these means the shoe is self-retaining, as set forth. The rivets or bolts, with their washers, which are applied to the runners near their ends, are designed to prevent the ends of the runners from splitting vertically when subjected to great lateral strain. These rivets or bolts re-enforce the runners at those points where the shoes are overturned and locked, and are very important features of my invention.

I am aware that sleds have been provided with round iron shoes seated into grooves made in the runner, and secured on top of the latter, at the ends thereof, by means of rivets. I do not therefore claim such devices.

What I claim,therefore, and desire to secure by Letters Patent, is-

l. The combination, with a sled-runner formed substantially as described, of a selfholding shoe adapted to fit the top and bottom edges of the runner, and having its ends overturned and locked thereto, as specified.

2. The combination, with a sled-runner formed substantially as described, of a shoe having overturned ends and adapted to fit the top and bottom edges of the runner, and the reenforcing rivets or bolts, substantially as specified.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

PATRICK H. oUMMINs.
