CADWALLADER M. RAYMOND, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO SAMUEL It. RAYMOND, OF SAME PLACE.

ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 313,622, dated March 10, 1885.

Application filed October 13, 1883.

To all whom, it may concern.-

Be it known that I, CADWALLADER M. RAYMOND, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Roller Skates, of which the following is a specification.

My invention relates to an improvement in extensible roller-skates; and it consists in cer- IO tain details of construction hereinafter fully set forth, whereby I am enabled to readily adjust and secure the skate to the boot or shoe of the skater, and to attain other special advantages.

Referring to the accompanying drawings, Figure 1 is a side elevation of askate embodying my invention. Fig. 2 is a top or plan view of the same. Fig. 3 is a bottom view. Fig. 4 is a vertical section of the hanger and elastic cushion. Fig. 5 is a transverse section of the same. Fig. 6 represents the clas tic or rubber cushion.

A B are respectively the toe and heel plates, composed of thin metal plate. The toe-plate A curves downward at a point marked d, and in the downwardly-bent portion is a slot of a width and length sufficient to allow the forward narrow portion of the heel-plate B to pass freely through from theupper to the under side of plate A, thus preventing any lateral motion, and admitting of an adjustable longitudinal movement of the two plates.

From the slot at d the narrow portion of the toe-plate A extends along the under side of the heel-plate B, through a slot formed by a recess, m, in the bearing-plate L, (see Fig. 5,)

and the rear portion of the heel-plate. The

front narrow portion of the heel-plate B passes forward through a slot between the under side of the toe-plate and the bearing-plate I, which is similar to that at the heel. It will be seen that the narrow ends of the toe and heel plates overlap respectively andconstantly the front and rear sets of rollers.

04 a are clamps connected to the forward part of the toe-plates, and are arranged to be adjusted to the width of sole of the boot or shoe to hold the same firmly.

b I) are clamps forming a portion of the heelplate. They are cut or stamped out at the (No model.)

same time with the heel-plate, and then bent upward, as shown, so as to hold the boot or shoe heel in place. A hole is made in said clamps for the purpose of attaching a strap when required.

A is a button or knob on the under side of plateA, for theattachment ofa toe-strap when necessary.

In the heelplate B .is an elongated slot or opening, (shown partiallyin dotted linesin Fig. 2,) the forward portion of such opening being narrower than the rear portion. To the upper side of the narrow portion of the heelplate 13 and in front of the elongated slot is pivoted,at D, a bent lever, O, and at the bent portion of" said lever is pivoted,at F, a fiat bar,

E. At the rear end of the bar E is ahole, through which passes a screw-bolt, G, which latter also passes through an opening in the heel-plate, and through one of a series of holes, 0, in the extension of the toe-plate A, and is secured by a nut, I. To the rear end of the bar E is also secured by the screw-bolt G a slotted plate, which turns upward and forms the clamp H, which is made to bear against the front of the heel of the boot or shoe. The clam pplate H,being slotted,is capable of being adjusted to the size of the heel, and is held to the plate A by the nut I and screw-bolt G.

In Fig. 2 the lever 0, bar E, and clamp H are shown as in a closed position by full lines and in an open position by dotted lines.

o is a teat or projection on the heel-plate B, to limit the backward movement of lever C.

When the skate is to be used, the proper length is first fixed by the adjustment of the toe and heel plates, so as to bring the clamps in proper position at the toe and heel of the boot or shoe, the lever O and bar E being in 0 an open position. The boot or shoe being then placed upon the skate, the lever O is drawn backward, a bent portion at the outer end beingmade to bear against the edge of the heel-plate 13, thus drawing the heel and toe 5 portions together, and causing the clamps to bind firmly on the heel and toe portions of the sole of the boot or shoe. The lever O is prevented from opening outward by means of its connection at the bent portion with the bar E, I00

so that the greater the force exerted against the lever O by the bar E the more firmly it will be held in position.

In drawing the heel and toe portions together, when the sole and heel of the boot or shoe are fitted in the several clamps, the sole will be contracted longitudinally, and thus cause the shank to rise or increase its curvature, and thus form a firm bearing and support for the hollow of the foot and for the instep, and thus conduce greatly to the comfort of the skater.

It is obvious that other devices may be employed to draw the heel and toe plates together for the purpose of fastening the skate to the bootas, for instance, a screw-threaded lug may be attached to eachplate, and a rod passed through said lugs having right and left screw-threads and suitable means for turning said rod; hence I do not confine myself to the lever device shown for drawing the plates together, as any means that will perform that function is within the scope and spirit of my invention, this part of which consists in fastening the skate to the bootby contracting the skate longitudinally.

To the under side of the toe and heel plates are secured the plates L L, carrying the inclined brackets M and N, to the lower ends of which are attached, by means of a pin, It, the hangers Q. in which are journaled the axles of the rollers K K. The pin It passes through a tubular passage, P, in the hanger Q, the upper portion of said passage or tube projecting above the upper end of the bracket, as indicated in Fig. 5.

Between the under side of the plate L and the upper side of the hanger Q is interposed a block of india-rubber,O, oftlie form shown in Fig. 6. In the upper side of said rubber block is a recess or cavity, which fits upon a teat or projection, Z, on the under side of plate L, and on the under side of the rubber block is a groove,which fits over the projecting portion of the tube 1?, by which means the rubber block is held firmly in position when the parts are secured together. The parts are shown as separated in Fig. 4..

I do not wish to be understood asclaiming herein the combination of the frameL, hanger Q, and spring 0, the same being specifically embraced in my application No. 139,181, filed J uly 30, 1884.

What I claim as my invention is 1. In a roller-skate, alongitudinally-adjustable heel and toe plate lapped together, the end of one plate passing through a transverse slot in the other plate, as and for the purpose set forth.

2. In a roller-skate, alongitudinally-adjustable heel and toe plate lapped together and the end of one plate passing through a transverse slot in the other plate, in combination with a lever connected with both plates, and adapted to lengthen or contract the skate by drawing said plates longitudinally, as and for the purpose set forth.

3. In a roller-skate, a fastening which consists of an adjustable toe-clamp and an adj ustable heel-clamp, connected, respectively, with longitudinally-adj ustable toe and heel plates, in combination with a lever or its equivalent for contracting or expanding the skate longitudinally and fastening the clamps to the boot,

as and for the purpose described.

4. The recessed plates L L, in combination with the heel and toe plates A B, the rubber block 0, and hanger Q. substantially as and for the purpose specified.

5. The toe-plate A,constructed with a curved portion and a slot, as shown. at d, in combination with the heel-plate B, as and for the purpose set forth.

6. In a longitudinally adjustable rollerskate, a fastening consisting of a lever pivoted to the heel-plate, in combination with a bar pivoted at one end to the toe-plate and at the other end to the lever, whereby the heel and toe plates are drawn together and the boot is clamped between the heel and the toe clamps, as and for the purpose set forth.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.
