UNirnn STATES WILBER F. CORNELIUS, OF MUNOIE, INDIANA.

ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 240,970, dated May 3, 1881.

Application filed March 14, 1881. (Model) To all whom it may concern Be it known that I, WILBER F. CORNELIUS, a citizen of theUnited States, residing at Muncie, in the county of Delaware and State of Indiana, have invented certain new and useful Improvements in Roller-Skates and I do hereby declare the following to be afull,clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked there on, which form a part of this specification, in which Figure 1 is a top view. Fig. 2 is a side view. Fig. 3 is a longitudinal vertical section. Fig. 4 is a perspective view of the hanger. Fig.5 is a perspective view of the two parts composing the front socket,in'which the hanger is seated. Fig. 6 is a perspective view of one of the sections of the toe-clamp.

A is a compound stock or foot-rest, composed of an upper plate, B, of malleable iron or other suitable material for receiving the required form,and a lower or bottom plate,(J, of elastic material, preferably-of steel, (although some of the elastic hard woods may be used,) for giving the required strength and elasticity with the minimum weight of material.

Near the front end of the plate B a recess is made across the plate, for the reception of the two toe-clamps D E for holding the front end of the skate to the shoe. These toe-clamps are angle-pieces of metal,as shown in Fig.6 of the drawings forming a part of this specification, the outer end being provided with a flange extending upward and curved inward, forming a lip, F, for creasinginto and holding onto the sole of the shoe. Near the outer end,beneath the flange of each toe-clamp, is a button, G, for the attachment of straps,to be passed over the toe of the shoe when desired. The clamps D E have about one-half of their breadth cut away from the inner side for about two-thirds of their length from the inner end, and have their inner edges notched, so that when they are in position,as shown in Fig.1 of the drawings, they will lap, and the notches will register and receive the pin H, thereby effecting the necessary adjustment. The pin H is an extension of an elastic bar, the end of which extends back under the plate B, and when the skate is in use is secured in its place by the weight of the foot.

To the back end of the plate B a heel-guard,

J, is placed, having an inclination sufficient to force the shoe forward between the toe-clamps upon the pressure of the heel upon the upper inner side.

In order to secure the requisite strength and wear in a skate takes place,) I have devised and adopted a truck of peculiar construction. This truck is composed of a plate, cushion, hanger, and thimble, and the necessary screws for holding the truck to the foot-rest, so constructed and arranged that by loosening the front screw the thimble may be raised, as shown in dotted lines of Fig. 3 of the drawings, and the post removed from its socket and the rubber readjusted or replaced.

To the bottom plate, (1, a combined socketand 7 spring cushion-plate,l, is secured in a suitable position near the toe. This cushionplate is of peculiar construction, being made longitudinally adjustable for a suitable distance by means of slotted ears K, one on each side and So one at the front end, through which screws pass into the plates 3 and O, holding the cushionplate securely in place.

The socket L, in which the spindle M of the hanger N is seated, is set at an angle of about forty-five degrees to the plane of the plate 0, and composed of part of the plate I, and extends above the surface, forming a flange for receiving the thimble 0, which closes in the post and extends to the front slot, and is held 0 down in place by the screw that holds the plate. This thimble has a lug on its under side for en gaging with the lug P of the post for the purpose of holding the post in place.

Just back of the socket L the plate I has a 5 recess, Q, for the reception of the spring cushion or bolster 1t, which may be of any suitable material or form, but preferably of rubber, and a cylinder whose length shall be about three times its diameter.

The post M is set on the crossbar of the hanger N at an angle of about forty five degrees from the perpendicular, so that the arms S S S S of the hanger N will project almost straight downward. This manner of seating the spindle of the hanger gives the desired curve movement upon pressure of the foot to either side. Opposite the post the hanger has a flange, T, in which is fitted a curved plate, M, and through which a set-screw, IV, passes, for adjusting the pressure upon the spring It. The four arms of the hanger N bear upon the axle X, upon which the rollers revolve. In cast in g the hanger the bearings for the axlein the two outer arms are cast open to the end, with straight sides, so that only the two inner arms have to be drilled to receive the axle. One end of the axle is cut square to fit one of the open bearings, so as to prevent the turning of the axle; and this arm of the hanger is provided with a lug, V, through which the linchpin Y passes, to prevent the endwise movement of the axle.

For the purpose of facilitating description, I have confined my description and letters of reference thus far to the front truck. The one under the heel differs from the one under the toe in no essential feature except this, that the lugs K at the toe have slots for adjustment, while no provision is made for adjustment at the heel, it not being necessary.

Having thus described my invention, I claim- 1. A compound stock or foot-rest for rollerskates, composed of a plate, B, of malleable iron, and a plate, 0, of steel, united substantially as shown and described.

2. An adjustable toe clamp composed of clamps D E, lips F F, and spring-pin H,-substantially as shown and described.

3. A cushion-seat for a hanger, composed of plate I, provided with a recess, Q, and the hanger N, provided with a flange, T, plate U, and adj usti n gscrew W, substantially as shown and described.

4. A socketfor the spindle of aroller-slrate, consisting of a plate, I, and thimble 0, substantially as shown and described.

5. A hanger for a roller-skate, provided with a spindle having a lug, P, and a flange, T, sub stantially as shown and described.

6. In a roller-skate, the combination of a hanger, N, having arms S S S S, and an axle, X, the outer arms of the hanger being open, with straight sides to fit the straight sides of the axle and prevent its rotation, substantially as shown and described.

7. In a roller-skate, the combination of a hanger provided with a lug, V, with an axle, X, and linchpin Y, substantially as shown and described.

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