ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 321,980, dated July 14-, 1885.-

(No model.)

To all whom, it may concern:

Be it known that we, ALVA L. KITSELMAN and DAVIS M. KITSELMAN, citizens of the United States, residing at Ridgeville, in the county of Randolph and State of Indiana,have invented a new and useful Improvement in Boller-Skates,of which the followingis a specification, reference being had to the accompanying drawings.

Our invention relates to roller-skates; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims.

In the drawings, Figure 1 is a view in perspective of a roller-skate embodying our improvements. Fig. 2 is a detail perspective view of one of the spiders which furnish the bearings for the journals of the wheel-hangers. Fig. 3 is a detail perspective view of one of the spiders and wheel-hangers, the wheels having been removed. Fig. 4 is a view in perspective of one of the wheel-hangers detached from the spider. Fig. 5 is a detail perspective view of one of the rubber cushions, washers,and screws for connecting the wheel-hanger and spider and regulating the tension, and so graduate it as to adapt the skates to and render them suitable for heavier or lighter persons.

Referring by letter to the accompanying drawings, A designates the sole of the skate. The spiders, wheel-hangers, &C., in this construotion for both the front and the rear 01' the sole are similar in construction. They are attached to the sole in the same manner, but in reverse positions. A description of one set of parts will therefore suffice for both.

B designates a small casting or spider, provided with four attaching-lugs made integral therewith, a downwardly-curved arm, 0, having a bearing, 0, near its lower end, and two bearing lugs, D D, projecting downwardly from the end of the casting opposite the curved arm 0. The cast-ing B is also provided with a screw-hole, E, at the upper end of the curved arm'O.

The wheel-hanger F consists of an inclined elongated plate, F, having a short transverse slot, F, and a hanger-frame, F depending from near the lower end of said inclined plate The inclined elongated and transversely slotted plate F is provided on its ends with journals G G. The journal G has its bearing in the lower end of the curved arm 0, and the journal G has its bearing between the lugs D D of the casting B. A rubber cushion, H, provided with a central hole, rests against the under face of the slotted plate F, and is held in place by a screw, I, passed up through a washer, J, of metal through the hole in the rubber cushion, then through the slot F and into the screw-hole E in the casting B. By tightening or loosening the screw I the tension may he graduated to adapt the skates to heavier or lighter persons, as may be desired.

In place of the washer J, the screw I may have an enlarged flat head, which will serve the same purpose, and will lessen the number of parts. Metal washers are interposed between the wheels and the hanger, and also between the linchpins and wheels. By this construction the hanger F carrying the wheels will be allowed a free oscillating or sidewise motion on its journals, and the rubber cushion held beneath the hanger will be alternately depressed on opposite sides by the movement of the wheel-hanger. In this manner the action of the skate is rendered much easier and of greater comfort to the wearer.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent of the United States, is

1. In a roller-skate, the combination, with the casting B, having the downwardly-extending arm C, having an opening, and the downwardly-extending lugs D, of the plate F, hav ing the journals at its ends, and the slot F, the hanger-frame F an elastic cushion hearing against the under side of plate F, and a screw, I, having its end passing through the elastic cushion and engaging an opening in casting B, as set forth.

2. The combination,with the casting B,having the curved arm C and bearing-lugs D D, of the wheel-hanger having the transverselyslotted plate F, the hanger-frame F, a rubber cushion, and a tension-screw passing through the opening in plate F and through the rubber cushion, and a metal disk or washer on the screw between the head of the same and the elastic cushion.

3. In a roller-skate, the combination, with In testiinony'that we claim the foregoing as the casting or spider having a downwardlyour own we have hereto affixed onrsignatures extending arin andapair of lugs, 01 the hanger in presence of two witnesses. carrying the wheels or rollers and having one 5 of its journals fitted in the arm and the other ALVA L. KITSELMAN.

resting between the lngs,a rubber enshiolnand DAVIS M. KITSELMAN. means, substantially as described, for holding the latter against the underside of the hanger \Vitnesses: and for holding said hanger in its bearings, J AMES MeANALLY,
