ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 308,025, dated November 11, 188%.

Application filed May 8, 188-1. (No model.)

To aZZ whom it may concern.-

Be it known that I, CHARLES II. WHITE, of Malden, in the county of Middlesex and Commonwealth of Massachusetts, have invented new and useful Improvements inRoller-Skates, of which the following is a specification.

My invention relates to that class known as rollerskates, and has for its object extreme simplicity of construction, combined with strength and great durability.

My invention consists, in general, in the means I use whereby I am enabled to obtain both a vertical and lateral elasticity for the foot-support, and particularly in the improved form and material in which the roller-frame and truck-frame are made, and, further, in the spring and improved clamp. The roller-frames are so connected to the hanger-frames that they are easily detachable.

Hitherto in roller-skates the elasticity of the foot-support has been best obtained by means of an elastic cushion or its equivalent, generally placed between a foot-standard, or a pressure-plate therein, and the upper surface of a truck-frame.

My invention enables me to entirely do away with any elastic cushion or other mechanism, and yet attain all the elasticity necessary for the performer to describe all the various evolutions desired while accomplishing dextrous and complicated movements.

In the accompanying drawings, Figure l is an elevation, with one of the front wheels removed, of my improved roller-skate. Fig. 2 is a detail sectional View of the same on line 00 m. Fig. 3 is a perspective view of the hangerframe or bearings. Fig. 4 is a perspective view of the truck-frame or roller-frame.

Similar letters of referenceindicate corresponding parts.

The foot support or standard is designated by the letter A, to which may be attached heel and toe straps or clamps, as desired. The footsupport may be composed of anysuitablematerial. I preferably, however, make it of struck-up sheet-steel.

B is ahanger-frame, firmly secured by screws to the foot-standard, and provided with bearings or coupling-ears b b for the spring D.

- clampto be opened.

0 is a truck or roller frame, provided with a bearing, 0, for the roller-axle, and socket d for the spring-rod D. h

Both the hanger and roller frame I preferably make of struck-up steel. I make the hangerframe and roller-frame the same for both the toe and heel of the footstandard. These parts are thus interchangeable.

The spring D, I preferably make of steel of the sectionalhshape to fit the socket d of the truck-frame, and of the general form shown; but I do not limit myself to this shape or form, as this red or torsion-spring could be round and nearly straight, in which case, however, it would not be so eifectual in its action.

My improved clamp is composed of the two sections E E Each sectionis firmly secured by a screw, 8, to the footstandard. This screw passes through an oblong slot in its section and allows the clamp to be moved in the line of the slot to and away from the center of the standard. A point or catch, 1), on the end of the sections E E is arranged to connect with sockets t, and hold firmly the sections of the clamp after the foot is inserted and the sections are pushed together. The pins 6 e are an integral part of the sections E E, and move with the sections in the slots in the footstandard, as shown. point p out of the socket, where it is held by the spring action of the socket, and allow the shown and described, has no rough surface to abrade the foot-covering, and while being very simple in operation is yet very effective in service.

In the construction a hanger-frame, B, is first secured-to the toe and heel of the standard, and both ends of the spring D, having been inserted through the socket d of a rollerframe, are sprung into position in the bearings of the hanger-frame, as shown in Fig. 1.

The peculiar construction and material of the hanger-frame and roller-frame, and the manner of their combination with the spring D, all unite to give a vertical elasticity. The spring D causes both the foot-standard and the roller-frames always quickly to assume a horizontal position when either has received a lat- They serve to raise the.

This clamp so made, as

eral motion by the movements of the performer. Any lateral movement of the stand ard or roller-frame operates to twist the spring D, the automatic resistance of which causes it to resume its normal position and produce the desired result.

' My improved skate is shown with four rollers; but I do not limit myself to any particular number.

I am aware that I am not the first to use a torsional spring in a parlor-skate; and I do not broadly claim this as my invention. It has been used for the purpose of keeping couplingbars in roller-skates on a line with each other and the central line of the skate. I know, however, of no roller-skate which has a torsional spring combined, as described, with a hanger-frame and roller-frame.

I believe I am the first to so use a torsional spring,whereby I obtain both a vertical and lateral elasticity from the foot-standard.

\Vhat I claim as my invention is- 1. In a roller-skate, the combination of the torsional spring D. with the roller-frame (land hanger-frame B, substantially as described ,and 2 5 for the purpose set forth.

2. In a roller-skate, a hanger-frame consisting of the plate B, provided with the pierced ear b and slotted ear b, to receive the spring D, substantially as described.

3. In a roller-skate, a roller-frame, 0, provided with the socket d for the spring D, and
