ROSSETER I. TOWLE, OF GUNNISON, COLORADO.

SAFETY-WHEEL FOR ROLLER-SKATES.

SPECIFICATION forming part of LcttersPatent No. 336,603, dated February 23, 1886,

(Modeh) To all whom it may concern:

Be it known that I, Rossnrna I. Town, of Gunnison, in the county of Gunnison and State of Go1orado, have invented a new and Improved Safety-Wheel for Roller-Skates, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved safety-wheel on the rear end of a roller skate to enable the skater to regain his equilibrium very easily and rapidly.

The invention consists in the combination, with a roller-skate,ot' prongs projecting downward from the rear end, and having a series of apertures for receiving a pin, a pin in one pair of apertures, and a roller mounted be: tween the prongs on the pin and having a series of eccentric apertures for receiving a locking-pin for locking the roller in place.

Reference is to be had to the accompanying drawings, forming part of this specification,

' in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a side View of a roller-skate provided with my improved safety-Wheel. Fig. 2 is a rear view of the same.

On the rear or heel end of the foot-plate A of the roller-skate a plate, B, is secured, from which two prongs, C, extend downward, and are then inclined downward and toward the rear, the lower parts, 0, of the prongs having a series of apertures,D,t'or receiving the ends of a pin, E, passed through the middle of the roller F between the said prongs. The pin E can be passed through the lower, middle, or upper apertures D, accordingly as the roller is to be held a greater or less distance above the floor. The roller F also has eccentric apertures H, through which apin, J, can be passed, the said pin being also passed through apertures D in the prongs,whereby the roller F is locked in place. When the roller is not to be locked, the pin J is held in apertures in the prongs O, near their upper ends. Adepts and experts need not have the roller F locked, as they are more experienced and can regain their equilibrium very easily. In case the skater is about to fall toward the rear, the roller F comes in contact with'the floor and enables the skater to regain his equilibrium. As the roller is free to tnrn,it does not act as a brake, and does not check the speed of the skater, which is of great importance, for if a person suddenly stopped in a crowded rink a number of other persons would also be stopped and considerable disorder would arise, and accidents might happen. as others would not check their speed at the same time. The roller F does not interfere with fancy or backward skating, as it is held sufficiently above the floor. Beginners lock the rollerF in place by means of the pin J, so that the roller acts as a brake and checks the speed of the skater as soon as it is brought in contact with the floor. As the-roller F has a series of apertures,H, it can be locked in different positions by the pin J, so that the same part of the rim will not always come in contact with the floor.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isa 1. The combination, with a roller-skate, of prongs projecting down from the rear end and having a series of apertures for receiving a pin, and of a roller mounted between the prongs on said pin, substantially as herein shown and described.

2. The combination, with a roller-skate, of prongs projecting down from the rear end and having a series of apertures, of a pin held in one pair of apertures, and of a roller mounted between the prongs on the said pin and having a series of eccentric apertures, substantially as herein shown and described.

3. The combination, with a roller-skate, of the prongs G, projecting downward from the rear end, the pin E in said prongs, the roller F on the pin, which roller has a series of eccentric apertures, and of the pin J, held in the prongs, substantially as herein shown and described.
