ROLLER SKATE.

. Application: filed ly 12, magseaa Nd. 4as7a I I This invention relate's to roller skates and more particularly to what er. mounting I term a new rollfor the front and rear skate axles whereby a greater roller contact surface 1s permitted and also prevents side slipping as when turning corners at a rapid rate of speed.

1 One of the objects of invention is to I provide a front and rear axle of a roller skate with a double set of rollers, thus producing practically an eight wheel skate, 1n-

stead of the usual four wheel, so

that the inner rollers of each set and the outer rollers may travel at difierent rates of speed when turning'sharp corners during fancy skating.

or speed To enableothers skilled in the art to fully comprehend the invention that they underlying features of my may vembody the same in the various modifications in structure and relation contemplated,drawings depleting a preferred form have been annexed as a part of this disclosure and in such drawings, similar reference characters denotev corresponding parts throughout views, of which,

Referring now to the drawings Figure 2 is a front View, partly in section. Figure 3 is a modified form of roller.

It will be observ considerable length so the sides of the frame ers. Instead of using rollers for 5 to support or other materials and mounted on 8 so as'to provide d thatthe axle 8 is of as to extend beyond the rolla single set'or two the front and rear of the skate,

terations therein may be made. I therefore independently rotatable, tral,.common scone 15, which may be solid or split, and provided with ball bearings 16, to assist in the operation of the respec- It will be readily appreciated that when making a sharp turn, the outside roller 14 may rotate much faster than the inside roller and vat the same time, there 1s V afi'ordeda greater roller contact surface, with the floor or cement so asto prevent slipping. This is particularly useful during fancy skating and speed skating and since the rollers-1S, and 14, both at the front and rear of the skate, provide a wider contact surface, it also permits beginners skating more quickly. Of course, of the threaded shaft Sear-e provided with the usual nut and Washers17, 18for the obvious purpose. The shaft 8 may be threaded throughout its length or maybe slotted to receive suitable cones and bearings for proper cooperation on the shaft.

I have 1 shown -a slightly In Figure 3 modified form of the invention which pre vents the admission of foreign matter between the inner and outer rollers 19, 20, by groove 21, near the outer edges of the said rollers 19, 20. In this form of the invention it is preferable to construct the rollers '19, 20,01 steel with a suitable groove engaging flange and as above described the usual type of cones and bearings are pro vided' for the shaft are mounted, V

Having thus described my invention, what I claim as new and desire to'secure by United States Letters Patent is 1 1. In a roller skate, a frame, front and rear supporting axles, pendently revolvable rollers axles, cones .on the shaft for of rollers, and ball bearings cones uponfwhich the rollers revolve.

2. In a roller skate, a frame, rear supporting axles, double sets on each of said double sets of indeeach of the sets mounted in said front and of independently revolvable rollers on each of the said axles, outside bearings for each roller a bearing between each of the said rollers, and means formed on the adjacent faces of the rollers for preventing accumulation of dirt therebetween. c i
