G. W. THOMPSON! SLEIGH RUNNER, No. 323,234. Patented July 28, 1885.

GEORGE \V. THOMPSON, OF SI-IIOKSHINNY, PENNSYLVANIA.

SLEIGH-RUNNER.

SPECIFICATION forming part of Letters Patent No. 323,234, dated July 28, 1885.

Application filed June 1, 1885. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. THOMPSON, of Shickshinny, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Sleigh-Rum ners; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in sleigh-runners; and it consists in the combi nation of the runner, a suitable clamping device which is connected thereto, and a castiron shoe which is connected to the runner by means of the clamp, as will be more fully described hereinafter.

The object of my invention is to connect a cast-iron shoe to a wooden runner by means of a clamp which is so constructed that when the shoe is worn out it can readily be removed and replaced by another.

The accompanying drawing represents aperspective of a portion of a runner embodying my invention.

Arepresents an ordinary wooden runner; B, the clamp, which is connected thereto by screws or rivets; and'O, acast-iron shoe, which is connected to the runner by means of the clamp. The upper portion of this clamp is so shaped as to receive the lower edge of the wooden runner, as shown, and the lower portion of the clamp has its edges or sides D thickened and made dove-shaped, as shown, so as to catch in correspondingly-shaped recesses I, which are formed in opposite edges of the shoe. This clamp will be made of steel or any other suitable material, and will serve to brace and strengthen both the runner and the shoe. The thickness 0 of metal serves to separate the runner from the shoe, and to unite the two sides of the clamp together in a single piece.

WVhen the shoe, which is to be made of castiron, is worn out or broken, it can be readily removed from the clamp and another one inserted in its place.

The cast-iron shoe is used in preference to a steel one, because the iron does not stick to stones and dry earth to the same extent as steel, and is not so liable to break as steel. In case the shoe should break while held in position by means of the clamp here shown, the shoe will not separate or become detached from the runner, but will be held in place, and can continue to be used untilan opportunity is afforded to replace it by another.

I am aware that the runner of a sleigh has been grooved so as to allow either a shoe or rollers to be attached thereto, and this I disclaim. Myinvention differs from thisin using a separate and distinct clamp for the purpose of securing the shoe to the runner, and which clamp and shoe can be readily detached from the runner at any time.

Having thus described my invention, I claim- The combination of the runner A, a clamp which is removably applied thereto, and the shoe, the upper edge of the shoe being clamped between the lower edges of the clamp, substantially as shown.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE WV. THOMPSON.
