PROVISIONAL SPECIFICATION.
Improvement in Sledges.
We, ROBERT HARVY JORDAN, and EWING MCCLEARY, both of Jefferson,
Greene County, Pennsylvania, U.S.A., Farmers, do hereby declare the nature of
this invention to be as follows:-
This invention relates to sledges; and the invention has for its object to make
the shoes thereof capable of being easily renewed when worn.
The runners of the sledge (usually made of soft iron,) are made with a dove-tail
groove on the underside and along their whole length.
Suitable rectangular blocks having tenons are fitted in the groove of each runner
and adjacent to each other.
The blocks are preferably made of hard steel, so that when in place they form a
continuous hard shoe.

COMPLETE SPECIFICATION.
Improvement in Sledges.
We ROBERT HARVY JORDAN and EWING MCCLEARY, both of Jefferson,
Greene County Pennsylvania, U.S.A. Farmers, do hereby declare the nature of
this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
Our invention relates to sleds, and its object is to obtain a runner-shoe or sole
which shall be simple in construction, durable, and capable of being easily and
cheaply repaired.
When sled-shoes are made of hard steel, they are very liable to break in cold
weather, being more or less brittle and unable to stand sudden strains or shocks.
But if made of softer and tougher steel, they rapidly wear out and require frequent
renewal.
Our invention aims to unite in one structure the good qualities of both kinds of
shoes. The invention consists in a shoe composed of short sections of hard steel,
placed close together, and suitably fastened to the runner.
Fig. 1 is a side elevation, partly in section of a bob-sled equipped with our
improved shoe.
Fig. 2 is a bottom plan view of a runner embodying our invention.
Fig. 3 is a transverse section thereof.
Fig. 4 shows the rear stop block.
Fig. 5 is a perspective view of a shoe section.
The invention is applicable to sleds and sleighs of all kinds.
A represents the wooden runner. To the bottom of this we secure a plurality
of short metallic sections B preferably made of cast steel or case hardened steel,
and preferably all of the same width and thickness, so as to present, when grouped,
a smooth even lower surface.
The advantage of this method of construction is that when any portion of the
shoe becomes worn or damaged, it can be replaced at a minimum cost by removing
the worn or damaged section and inserting a new one.
Various ways of attaching the sections to the runners suggest themselves. We
prefer however the one shown.

page_text: Bolted firmly to the bottom of the runners A is a strip of metal C, preferably
soft, tough steel, having a dove tail groove c in its under side.
The upper end of each shoe section has a dove tail tenon b adapted to fit snugly
into the groove c.
The front end of the strip C abuts against a steel block D
curved to fit the front of the runner, & serving both as a bumper, and as a front
stop to the sections B. The latter are slid into the groove c until it is nearly filled.
Then the rear stop block E is slid in and bolted in place, holding all the sections
firmly together.
The tough strip C prevents the shoe from breaking completely in two, while the
hard sections B resist wear.
Should any section become broken or badly worn, it can easily be removed by
taking out the rear block E and sliding out the sections.
Among other advantages, possessed by this shoe is that of running easily over
bare spots in the road.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
1. A sled-shoc consisting of a plurality of short sections secured to the runner,
substantially as described.
2. A sled-shoe consisting of a plurality of short sections of hard steel secured to
a strip of tougher metal, substantially as described.
3. A sled-shoe consisting of a strip of metal having a dove tail groove and a
plurality of sections having dove-tail tenons fitting into said groove, substantially
as described.
4. A sled-shoe consisting of a strip of tough metal having a dove-tail groove,
and a plurality of short sections of hard metal, each having a tenon fitting said
groove, substantially as described.
5. The combination with the sled runner, of the strip C. having dove tail
groove c, the sections B having tenons & fitting said groove, the block D, and the
stop E, substantially as described.
