ROLLER SKATE.

Application filed December 6, 1921. Serial No. 520,412.

To all whom it wwy concern:

Be it known that I, Fmonmon B. Srnoss, a citizen of the United States of America, residing at Churchville, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Roller Skates, of which the following is a specification.

The object of this invention is to provide a new and improved type of roller skates.

This and other objects of this invention will be fully illustrated in the drawing, described in the specification and pointed out in the claim at the end thereof.

In the accompanying drawing:

Figure 1 is a front elevation of the roller skate for; the left foot.

Figure 2 is a side elevation of this roller skate. V

Figure 3 is a top plan view of the roller skate.

Figure 4 is a detail view of a portion of the roller skate.

' i In the several figures of the drawing like reference numerals indicate like parts.

The

to the shoe and practically form a part thereof. The control of these roller skates is, therefore, solely dependent on the skill of the operator in the movement of the feet and the balancing of his bodywith relation thereto. i

In the present invention another controllingelement is added with which it is possible to stop the wheels of the roller skates at will by means of a movement of the leg of the operator.

The construction of the roller skates embodying this additional controlling means comprises a. wheel 1 which is mounted on the outside of the foot support 2. The foot support is made up of the upright 3 having the horizontal bracket 4 bent out at the bottom thereof to provide a small platform thereon for the heel of the operator to rest thereon.

At a short distance above the lower end of the upright 3 is fastened the angular brace 5 which projects forwardly thereof and has the platform 6 bent out in a hori- 'zontal plane therefrom. The front of the foot of the operator is adapted to rest on the additional platform formed at the front of the upright. The outer end of the platform 6 is braced from the upright 3 by the without undue friction type of roller skates that are being used at the present time are rigidly fastened brace 7 which extends from the flange 8 I turned up at the outer end of the platform t3 to a suit-able point on the upright 3 leaving room for-the foot of the operator to pass under it and rest on the platform 6.

The pivot pin 9 on which the wheel 1 is mounted to rotate is carried on the angular brace 5, suitable ball bearings being provlded thereon to make the wheel rotate in its bearings. Extending rearwardly from the upright 3 is the bracket 10. The bracket has a fork 11 formed at the end thereof in which the idle wheel- 12 is mounted to,rotate. The wheel 12 is adapted to partially support the upright 3, and hold it in its upright position.

Also fastened to the fork 11 and projecting up therefrom is the brake band 13. This band curves forwardly and over hangs a portion of the top of the wheel 1. At a point intermediate of the brake band 13 is provided a lug to which the link 14 is attached. This link is connected to the rearwardly projecting bracket 10 by means of the turnbuckle 15 for the purpose of operating the brake therewith. As illustrated in the figures, the fork 11 formed at the rear end of the bracket 10 is made flexible on the bracket by twisting the bars forming the fork at 16 and 17 to ,make the end of the fork resilient on the end of the bracket. This is for a purpose that will presently appear.

The foot of the operator is placed on the platforms 4 and 6 with the leg of the operator placed adjacent to and parallel with the upright 3. The strap 18 provided at the upper end of the upright 3 is then fastened around the leg of the operator who thus has the roller skate securely fastened to his leg. It will be understood of course that a similar roller skate is fastened to the right leg of the operator to enable him to skate in the manner similar to that practicedwith the old style roller skates.

The skates can be stopped individually by applying the brakes on the wheel 1. This is done by rocking the upright slightly to the rear around the pivot pin 9. The fork 11 carrying the wheel 12 is slightly bent for this purpose and this is made possible. by the resiliency thereof as heretofore pointed out. In bending the bracket 10 the link connection between it and the brake band 13 operates to bend the brake band and forces the outer and free end of the brake band of This stops against the tire of the wheel at the top therethe wheel and prevents any further rotation of the wheel until the brake band is released by allowing the upright 3 to swing back to its vertical position. The movement of the upright 3 necessary for the purpose of applying the brake is Very slight as indicated in the dotted line position shown in Figures 2 and 4.

I claim: 1

A roller skate, comprising an upright, a platform mounted at the lower end of said upright, a stud supported by said upright and projecting away from said platform, a wheel mounted to rotate on said stud, a flexible bracket extending rearwardly between said wheel and said platform, a. secsecond wheel, said brake band being curved to overhang a portion of the first of said wheels, with the free end thereof, a link connection between the free end of said brake band and said bracket, said link connection operating to bend the free end of said brake band and bring it in contact with the periphery of the first of said wheels when bending said bracket by means of said upright. 1

In testimony whereof I afiix my signature.

FREDERICK B. sPnoss.
