WILLIAM A. sorrow, on NEW YORK, N. Y.

ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 249,556, dated November 15, 1881.

7 Application filed March 3,1881.' (No model.)

To all whom it may concern Be it known that I, WILLIAM A. SUTTON, of the city, county, and State of New York, have invented certain new and useful Improvements in Roller-Skates, of which the following is a specification.

This invention has reference to an improved construction of parlor-skates by which -the roller-frames are cushioned in a simple manner at the inclined parts of their bracket-plates, so as to be returned to the center by the action of the cushion whenever the side pressure is discontinued.

The invention consists of a skate provided with bracket-plates, to the inclined parts of which the roller-supporting frame is pivoted. Between a transverse and a central lip of the step-shaped front portion of the roller-supporting frame is interposed a rubber cushion, which returns the rollers into line with the axis of the skate when there is no side pressure exerted thereon.

In the aecom pan yin g drawings, Figurel represents a side elevation of my improvedparlor-skate. Fig. 2 is a detail vertical longitudinal section of the same; and Figs. 3 and 4 are perspective views, respectively, of the rollersupporting frame and bracket-plate.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents the sole-plate of my improved parlor-skate, which is made of wood or other suitable material.

To the under side of the sole-plate A are at tached, near the front end and at the rear end, angular bracket-plates B B, to the downwardlyinclined portions of which the roller-support- Each frame 0 carries two rollers, which turn loosely on a transverse connecting-shaft of the frame 0, and which are separated by an intermediate At the apex of the angle formed by the horizontal and downwardly-incliued portions of each bracket-plate is arranged a transverse lip, a, at right angles, or nearly so, portion of the bracket-plate,

which projects to the inclined and which serves,

a in connection with a step-shaped front portion,

O, of the roller-supportin g a rubber cushion, roller supporting frame 0, to support E. The inner edge of the frames 0 G is made arelip of each bracket-plate I shaped, and provided at the central part witl an upward-projecting lip, b, that engages tht middle portion of the rubber cushion E. Th1 center lip, b, serves for centralizing the roller: when there is no pressure on them, while thi arc-shaped front edge admits the ready turn ing of the roller-frames on their pivots. Thr cushioning rubber plate E is firmly retainec' by the transverse lip a of the bracket-plate the stepped portion 0 of the rubber-support ing frame, and the central lip, b, of the same. these parts formingakind of box,within which the rubber cushion is inclosed, so that it cannot play loose or get detached therefrom.

If necessary, a new rubber cushion may be put in at anytime by simply detaching the roller-supporting frame from the bracket-plate by unloosening the screw pivot and replacing the roller-frame when the new cushion is put in. As each part of the skate, the bracketplates with their lips,the step-shaped rollersupporting frames with the central lip, are cast and finished separately, they are readily assembled on the sole-plate and form a yielding, durable, and reliably-workin g roller-skate for general use.

It will be seen from the above description that the transverse part of the roller-bearing frame 0 is in contactwith the lower side of the inclined part of the bracket B, thus affording a firm and positive bearing of the said frame and preventing wabbling thereof when the skate is in use.

It will also be seen that in addition to the advantages above stated I locate the rubber cushion well back of the pivot which connects the roller-frame to'the bracket, thus affording a long leverage, which enables me to use a small block of rubber in it will be seen by reference to Figs. 1, 2, and 3, is below the plane of the top side of the roller-frame. l

I am aware that it is not new to interpose' pieces of india-rubber between the roller-frame or caster and an inclined bracket to which said frame or caster is pivoted, and therefore I do not claim this feature when broadly considered.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. For a roller-skate wherein an india-rubber block is used between the roller-frame and.

the pocket (3, which,

bracket, the angular bracket B, constructed with the transverse lip a, located at the angle formed by the horizontal and downwardly-inclined portions of said bracket, substantially as described.

2. For a roller-skate wherein an india-rubber block is used between the roller-frame and bracket, the frame 0, constructed with the transverse elongated depressed pocket 0 and the retaining-lip b, substantially as described.

3. The angular bracket B, constructed with the lip a1, and the roller-bearing frame 0, constructed with the depressed pocket 0 and transverse lip or shoulder b, in combination with the rubber cushion, substantially as described.

. 4. For a roller-skate, the bracket B, con structed with the transverse lip or shoulder a,

in combinationwith the roller-frame O, bearing directly against the inclined. portion of 20 said bracket and pivoted thereto, and having a rubber cushion located in rear of the axis of the pivot, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence 25 of two witnesses, this 26th day of February, 1881.
