HARRISON N. M. SMITH, OF PHILADELPHIA, PENNSYLVANIA.

IMPROVED SKATE.

Specification forming part of Letters Patent N0. 52.331, dated January 30, 1866.

To all whom t may concern:

Be itknown that I, HARRIsoN N. M. SMITH, of Philadelphia, in the county of Philadelphia and State ot' Pennsylvania, have invented an Improved Skate; and I do hereby declare th at the following is a full, clear, and exact description of the same, reference being had to the Iaccompanying drawings, and to the letters of reference marked thereon.

The nature of my invention consists individing a skate transversely into two parts, which are hinged together, and in using a sliding heel-pin.

To enable others to make and use my invention, I will proceed to describeits construction and operation.

On reference to the accompanying drawings, which form a part of this specication,Figure l is a plan view, and Iiig. 2 is an elevation sectioned at the heel;

Similar letters refer to similar parts in the two views.

A is a skate, divided transversely at the line a b, the two parts or portions being held together by the hinge c, attached to the Itreads B and O.

There are two runners, D and E, which lie in the same longitudinal plane perpendicular to the treads B and C, one being attached to each tread. It will be observed when the two treads are in the same right line the distance between the toe of the skate and the heel-pin d is greater than when they are placed at an angle to each other (Fig. '2, red lines) to preserve the same distance. Whether the treads are in the same right line or at an angle to each other, I use a sliding heel-pin, which in this case is constructed land arranged as follows: A slot or opening, @,is cut in the heel ot' thetread. Beneath this a plate, f,isattached. which is so slotted that its edgesgg shall project slightly over the edges ot' the opening e. A stand or collar, h, is formed on the bott-om ot' the heel-pin, from which projects the screw l. The stand h tsA snugly into the recess or opening aand rests upon the platej', the screw projecting sufficiently to screw on a nut, w, which keeps the pin from lifting, and at the same time allowing it to move freely longitudinally back and forth in the opening. The use of a heel-strap is entirely dispensed with.

I do not coniine myself to any particular deseripton ot' a heel-pin or any method of fastening it for carrying out my invention, as it will be seen thatit may be materially modified; but

What I claim as my invention, and desirefto secure by Letters Patent, is

l. A sliding heel-pin, for the purpose a herein shown and described.

2. The combination of the sliding heel-pin d and the hinge or joint c, as is herein shown and described.

In testimony thereofl I have hereunto signed my name to this specification in presence ot' two subscribing witnesses.

HARRISON N. M. SMITH.
