Letters Patent No. 108,917, dated Novemberl, 1870.
mpnovsmznr m SLElGH-RUNNERS.
The Schedule referred to in these Letters Patent-and making part of the sam.
To all whom it may concern Be it known that I, J OI-IN LOGAN, of Waterloo, in
the county of Black Hawk and State of Iowa, have invented a new and valuable Improvement in Sled- Itunners; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawing is a side view of my invention. I
Figure 2 is a central vertical longitudinal section of the sam e.' Figure 3 is a top view of the runner.
Fi ure 4 is a bottom view, showing the steel shoe.
Figure 5 indicates the manner of applying and letting in the chilliiu casting'the runner. a
My invention relates to-cast-iron runners for sleds, and consists mainly in the construction and novel arrangement of devices whereby such cast-iron runners are shod with steel in a simple and durable manner.
The letter A represents the body of a east-iron runner.
a represents the steel shoe, tbrked and dovetailed at each end. The shoe is sprung into place, and when in position is prevented from coming out at the ends by the dovetailcd'joint, theforked shape of which enables it also to operate in the prevention of any sidewise movement.
The shoe is permanently secured to the runner with tapered bolts b b and nuts 0 c, for convenience in the application of which the openings 1: o are made in the cast runner below the knees B B.
The tapering form oi the bolts 7) b operates to prevent their becoming loose as the steel shoe wears awa D rcpresents the top of the knee, to which is bolted the beam and rav r To the lugs z 5, cast on 'eachside of the front end of the runner, is bolted-the end of the rave, which is inortised to receive the projection a.
On the inner side of the runner, under the plate or knee-cap D, are the braces e 0, between which rests the end of the cross-beam. i The knees B B are still further strengthened by the braces l 1, connecting the upper part of the knee-oneach side with the upper edge of the sled-runner.
In the cast body of my runner lightness has been obtained by economy in the. use of metal, strength being preserved by the flanches m m, which bound the runner and knees on the inside and outside edges.
.In casting the runner a chill, s, which expands as the hot-metal is poured on its upper face, is let into the runner at each end to the depth of one-eighth of an inch or more.
The letter a designates the bearing for one end of"
