EDWIN CHESTERMAN, OF PHILADELPHIA, PENNSYLVANIA.

COMBINED RUNNER AND ROLLER SKATE.

SPECIFICATION forming part of Letters Patent No. 226,835, dated April 27, 1880.

Application filed January 5, 1880.

To all whom it may concern:

Be it known that I, EDWIN OHEs'rERMAN, of the city of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Combined Runner and Roller Skate, which improvement is fully set forth in the following specification and accompanying drawings.

The object of this invention is to convert an ordinary runner-skate into a roller-skate without removing the runner.

The invention consists of rollers and axles, one or more, adapted to be attached to a runner-skate without removing the runner; also, of roller-frames and rollers, one or more, and a clamp or clamps, by which said roller-frames may be fastened to or removed from the runner of a skate; also, of the combination, with a runner-skate, of axles and rollers, one or more, in such manner that said axles and rollers may be readily attached or detached without removing the runner from its frame and without impairing said runner for its primal use.

Referring to the drawings, Figure 1 is a perspective, showing a runner-skate with my invention attached. Fig. 2 is a vertical section of my invention. Fig. 3 is a modification of my invention, showing the axle pivoted to the clamp to facilitate a curved movement.

A represents an ordinary runner-skate. A is the sole-plate. B is a clamp, in the present case made with an axle or spindle, B, projecting on each side, which spindle is made hollow for the double purpose of diminishing its weight and to admit a screw by which the axles are attached to the skate A.

b is a collar formed on the axles. I) are holes for the linchpin, which will be hereinafter described. I) is a female screw formed in the hollow axle, and c is a screw by which the axle is clamped to the skate A.

G are rollers or wheels which revolve on the axles, and c are linchpins by which said rollers are held on the axles. These linchpins are made of the form shown, the distance between the two shoulders being a little less than the diameter of the axles. The two ends or points projecting toward each other from said shoulders are of a length equal to the thickness of the shell of the axle. When the roller is put on its axle and the linchpin sprung into its position said linchpin will press against the axle with force sufficient to hold its points in the holes and retain the rollers on said axles, and the hollow in the axles will be left unobstructed for the application of the proper tool to turn the set-screw, by which the axles B are attached to or detached from the skate A.

Fig. 3 shows the clamp and axle made in separate pieces. The clamp has a pivot ex tending downward, and the axle is enlarged and provided With a tubular bearing in the middle, so that the axle may turn on the pivot of the clamp to facilitate a curved movement If desired, a clamp may be extended upward from the axle and fastened to the edges of the sole-plate instead of to the runner; or the clamp may be formed with clips or hooks to fit over the top edge of the soleplate, in which case the clamp would be passed up over the runner to the top of the soleplate at its narrowest part, and then moved forward or backward to the wider parts, and when in the right position a set-screw would be tightened and the clamp, wit-h its axle and rollers, be firmly'attached to the sole-plate.

This and other modifications may be made without departing from the spirit of this invention.

It will be readily seen that the herein-described attachment may be applied to any ordinary runner-skate by simply tightening the set-screw, and removed by loosening said screw, and that no alteration is required in the runner-skate; neither is said skate in any way injured.

Having described my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. In combination with axles having rollers attached thereto, a clamp, B, and set-screw c, where by said axles may be readily fastened to or removed from the runner of a skate without removing it from the sole-plate or impairing its use as a runner, substantially as set forth.

In combination with the skate-runner A, a hollow axle, B, having clamp B, female screw b and set-screw c, with rollers (l attaehed to said axle, substantially as and for ing the runner from the sole-plate or impairthe purpose described. ing its use, substantially as and for the pur- 3.
