GILES H. CROSBY, OF ROME, OHIO.

IMPROVEMENT IN SLElGHS.

Specification forming part of Letters Patent No. l 54,847, dated September 8, 1874; application filed July 2l, 1873.

To all whom it may concern:

Be it known that I, GILEs H. CROSBY, of Rome, in the county of Ashtabula and State of Ohio, have invented new and useful Improvements on Sleds, of which the following is a full, clear, and complete description, reference being had to the accompanying drawings, making part of the same.

Figure l is a plan view of thel sled. Fig. 2 is a side view. Fig. 3l is a view of the rear end. Figs. 4 and 5 are detached sections.

Like letters of reference refer to like parts in the several views.

rIhis invention relates to a sled; and the first object thereof is the construction of the runners'of wrought or cast iron, steel, or of wood and, secondly, the attachment of the runners to the sled by means of a free joint, whereby is obtained to said runners a vertical vbratory movement.

Of the above-speciiied'invention the following is a description in detail. j

The sled referred to is of that classy popularly known as bob-sled, and of which A A represent the runners; B, the beams to which they are attached 5 C, the bolster, and D the rails or reaches, whereby the front and hind parts are connected to each other. The runners, as aforesaid, are made of iron, and, in detail of parts, consist of the runner E, Figs. l and 3, to the under side of which is secured the shoe F, forming an under rib. On the upper side of the runner is a web, G, the peculiar shape of which and its several parts will be understood by the inspection of Fig. 2.

y Said runners, composed of the several parts described, are made of rolled iron or steel, or of ordinary cast-iron.

In order to attach said runners to the sledbeam in the manner alluded to, there is formed on each side of the web Gr an angular flange, H H', Fig. 3. The apex of the angle forms an eye,through which passes the axial bolt a, and which eye also constitutes a section of the joint and knee of the sled-runner. The corresponding part of the joint consists of a stay, I, between the ears c of which is fitted the apex of the. angular flange referred to, as shown in Fig. 3, through which and the eye of the flange the bolt passes, thereby forming a jointed connection of the runner to the beam. Said stay isbolted to the under side of the beam, as shown in Fig. 2, in which it will be seen that the plate of the stay is provided with two flanges, d, between which the lower sides of the beams are held, as shown in Figs. 2 and 3, thereby making its connection to the beams more secure.

For the iron runners A referred to may be substituted wooden ones, of which Figs. 4 and 5 represent a detached runner. In order to attach the wooden runner J to the beam, a stay, K, Fig. 1, is secured to the ruimer. which, in its construction, closely resembles the stay I. The runner-stay J is fitted and secured to the beam with a pivotal bolt, in the same manner as the iron runners are.

The bolster is attached to the front beam by a king-bolt.v Said -bolt and the rub-plate are in one piece. The head of the bolt is oblong in shape, and which is made to fit in ahole in the corresponding rub-plate on the upper side of the beam. Said hole is lengthwise the beam, whereas the head of the bolt is transversely therewith. Hence, to allow the head of the bolt to enter the hole in the plate, the beam is brought around to a position at right angle tothe bolster, which, when the bolster and the beam are again parallel, the bolt-head cannot pull out.

I-am aware that the shoe or rib F has been known and used by others before me. Hence, I disclaim the same; but what distinguishes my invention are the improvements herein claimed.

What I claim as my invention, and desire to secure by Letters Patent. is-

l. The runners A A, provided with angular lian ges H H, the apex forming an eye for the admission ofthe axial bolt a, in combination with the stay I, to form a jointed connection of the sleigh beam and runner and beam B, substantially as and for the purpose set forth.

2. The wooden runner J and stay K, in combination with the stay I and sled-beam B, as and for the purpose set forth.
