DOMINIOUS BRIX, or GENESEO, ILLINOIS.

ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 308,744, dated December 2, 1884.

Application filed April 1, 1884. (No model.)

To all whom it may concern Be it known that I, DoMINIoUs BRIX, a cit-izen of the United States, and a resident of Geneseo, in the county of Henry and State ofIllinois, have invented certain new and useful Improve ments in Roller-Skates; and'I do hereby declare that the following is a full, clear,- and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, refer-- ence being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a side view of a roller-skate em bodying my improvements. Fig. 2 is a front view of the same, and Fig. 3 is a cross-section through line 00 0c in Fig. 1.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to roller-skates; and it consists in the improvements in the same which will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings, A denotes a roller-skate 'of any approved construction, having the usual rollers, B. I prefer to construct these rollers with a rubber tire slipped into a groove in the periphery of the rollers for the purpose of making them run noiselessly.

Fastened upon the front and back part of the skate, immediately in front of the front pair of rollers, and back of the hind pair of rollers, is a short metallic bar, D, the lower end of which has a cross-head, E, which may be pivoted and swiveled, at 0, upon the lower end of the bar. This cross-head is provided with a rubber roller, F, and, if desired, t his bar or pendant D may be made in two parts, one screwed into the other, so that the bar may be lengthened or shortened at will.

Fastened to opposite sides of the foot-plate are downwardly and outwardly projecting arms or outriggers G, at the lower ends of which are small rubber rollers H, so arranged that these rollers will project from a quarter tohalf an inch outside of the main rollers B, and lifted about one-fourth of an inch from the lioor or ground. It will be seen that the moment the ankle bends, so as to tiltthe skate sidewise, these rollers or Outriggers H will touch the floor, and thus prevent the ankle from being sprained by doubling over. It will also be seen that the front and rear brakebars, D, will prevent the skate from tipping over forward or backward, and that the operator can come to a sudden stop at any time simply by tipping his skate, so as to bring either one of the brakes into frictional contact with the floor.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. As an improvement in rollerskates, the Outriggers G G, placed on opposite sides of the foot-plate between the rollers, and provided with rollers at their outer ends, substanti ally as set forth.

2. As an improvement in roller-skates, the brakes consisting of the front and back bars or pendants, D D, having cross-heads E at their lower ends, provided with rollers F, sub stantially as set forth.

.3. As an improvement in roller-skates, the brakes consisting of the extensible front and back bars or pendants, D D, arranged respectively in front of and back of. the rollers B B, and provided with the hinged or swiveled cross-heads E, having frictional rollers F, substantially as and for the purpose shown and set forth.

4. The improved roller-skate herein shown and described,'providedwith the outriggers G, having rollers H, and having the front and back brakes, D, provided with cross-heads E, swiveled at C, and having friction-rollers F, the whole constructed and combined substantially as and for the purpose shown and specified.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.

DOMINICUS BRIX.
