To all it may concern:

Be it known that I}, BENJAMIN FRANKLIN SPENCER, a citizen of'the United States, and

formerly a resident of Atlanta, in thecopnty of Fulton and State of Georgia, but now residing in the city of Los Angeles, State of California, have lnvented certain new and useful Improvements in Roller-Skates, of which the following "is a specification.

My invention relates to roller skates, and the purpose of the invention is the provision of a skate in which the'foot plate and clamping plates as well as the supporting brackets for the wheel are formed from a single sheet of metal, thus permitting the stamping ofthe same and .thereby materially reducing the cost of manufacture.

It is also a purpose of my invention to provide a roller skate in which the clampmg members are positioned to effectively embrace the foot for securely retaining the 'skate thereupon. j

I will describe one form of roller skate embodying my invention, and will then point out the novel features thereof in The brackets C and C being bent inwardly,

claims. v

In the acompanylng drawings Figure 1 is a View showing in phantom a shoe havin skate embo ying my invention;

F1g. 2 is a view, showing in front elevation the skate shown in Fig. 1;

I Flg. 3 1s a vertical sectional view through the wheel and supporting brackets; Fig. 4 is a view, showing the body of the skate as it is stamped from a single piece of metal and before it is bent into the forms shown in Fi land 2.

Similar reierence characters refer to similar parts in each of the several views.

Referring specifically. to' the drawings,

and particularly to Fig. 4, F designates a arms A and A which constitute the toe clamp of the skate; At the rear-end of the foot plate, it is provided with an upwardly extending extension E at the free end of which latter is carried a pairof forwardly applie thereto one form of Specification of Letters Patent. Patented Mar. 1, 1921.- Application filed January 23, 1920. SerialNo. states. A"

and upwardly curved arms B and B which constitute the ankle clamp of the skate. Depending from and formed integral with the foot plate are a pair of brackets C and C which are curved inwardly, as clearly'shown in Fig. 2 and are formed with o enings 15, as shown in Fig. 4 through which an axle D extends, as clearly shown in Fig. 3; Arranged between the free ends of the brackets C and C and surrounding the axle D is a wheel W, while interposed between the hub of the wheel and the axle is a bearing sleeve S which loosely embraces the axle so that the wheel W can be'freely rotated upon the latter. I

By reference to Figs. 1 and 2, it will be seen that the 'curvatureo'f the arms comprising the angle clamps and toe clamp are such that they securely embrace the same and thereby "effectively maintain the skate in applied position upon thefoot. As these clamps are formed lntegral with the foot plate F, it is obvious that the employment of securing devices of various characters as in the usual form of skate 1s ellmmated.

festly permits of the rapid making of the skate at a minimum cost as compared to oller skates of the usual-construction. Although I have herein shown and described only one form of roller skate embodying my invention, it is to be understood that various, changes and modifications may be resorted to without departing from the spirit of the invention and the spirit and scripe of the appended claims.

aving thus described my invention, I

claim 1. A roller skate comprising, a body formed of a single sheet of metal comprising, a foot plate, armsextending upwardly and, inwardly of said plate adjacent the forward end.th ereof and adapted to engage thetoe portion of the foot, an extension on the rear end of the plate, ankle embracing arms on the 'free end of saidextensiomsaid arms extending forwardly, inwardly and upwardly with respect to said plate, and brackets' depending from said plate intermediate its ends, and a wheel journaled in 5 said brackets.

2. A roller skate comprisin a wheel supported foot plate, a pair 0 substantially rigid arms arranged on the body for clampingly engaging the toe portion of a foot, and a second pair of substantially rigid 10 arms on the body and arranged to embrace the ankle and to normally prevent displacement of the foot from the first pair of arms.
