VVELOCIPEDE-TREADLEQ SPECIFICATION forming part of Letters Patent 1%. 533,867, dated February 12, 1895.

Application filed December 22,1898. serum. 494,427. (No man Be it known that I, ALBERT B. ems, of

I the city and conntyof Worcester and State of Massachusetts, have invented certain new and useful Improvements in Velocipede-Pedals; and I do hereby declare that the followmg is a full, clear, and exact description thereof, reference being had to the accompanying drawings, forming apart of this speci fication, in which-' Figure 1 represents a plan of my improved pedal. Fig. 2 is a side view; Fig. 3, a bottom View, and Fig. f an end view thereof. 7 Fig. 5

is a central, transverse section through the pedal. .Fig. 6 is a perspective view of the metal holding-plate of'one of the detachable foot-rests of the pedal, hereinafter described.

. Fig. 7 is an end view of one ofv said detachplying said'removable foot-rests, as will be able foot-rests, with its holding-plate secured hereinafter more fully set forth.

In order that others may better understand the nature and purpose of my said invention, I will now proceed to describe it more in detail. v

-With the exception of the aforesaid detach 'able foot-rests, the rat-trap pedal shown, is of well known construction, and, therefore, re-

quires only a general description'in connec-' tion with said improvement. It is provided with the usual, central spindle A, end-plates B B, sleeve 0, arranged over said spindle betrap plates E E, extending between the outer ends of the end plates and serving as foot rests for the pedal when used as a rat-trap pedal without my improved, cushioned, detachable foot-rests Said foot-rests F F, may be made of any suitable shape or material. I prefer,however, to make them of rubber, and with their top surfaces a, fiat and roughened, as is shown in the drawings, so that the feet of the velocipede rider may more perfectly fit and adhere thereto. Each foot rest is provided with two inwardly projecting,

parallel plates 1) b, arranged just far enough fastened in position after adjustment by means of short bolts 0, and nuts d,'saidbolts being passed transversely through suitable openings bE in the plates 1) b and E, respectively, as is shown in the drawings. Said parallel plates 12 b project at right angles from a horizontal, tubular bodyf, and both the plates and body are preferably made integral,from a single piece of sheet metal, of the proper size and-shape to produce said parts when bent into substantially the shapes shown in Fig. 7. The tubular partf, and a portion of the base or inner ends of the parallel plates 1) b are embedded in the elastic foot-rests F F in casting the latter, and are thereby securely fastened therein, as is fully shown in the drawings. To facilitate fastening said tubular bodies in'the foot-rests, they may be provided with a series of holes f for the material from which said foot-rests. are cast to enter, and thereby more securely hold the metal part in position.

If desired, the body f may be made flattened in the form of a double plate f as is shown in Fig. 8. e

In applying the detachable foot-rests to convert an ordinary rat-trap pedal into a cushioned pedal, the rider has but simply to slip the holding-plates b I) over the outer edges of the rat-trap plates E E, then pass the transverse bolts 0 through the openings 1) E in said plates, and turn the nuts d thereon; and the removal of said foot-rests, it is obvious,

. may be performed with equal facility by reversing said operation. tween said plates, dust-caps D D, and rat- Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In rat-trap, and similar pedals for velocipedes, detachable foot-rests, adapted to be applied to the rat'trap plates, and. having parallel holding plates projecting therefrom,

adapted to be fitted to said rat-trapplates,.

and means for fastening said holding plates to the rat-trap plates,substantially as and for the purpose set forth.

2. In rat-trap and similar pedals, the detachable foot-rests F F adapted to be applied to the rat-trap plates, in combination with an irregular shaped, metal holding plate fastened thereto, by embedding a portion thereof in said foot-rest, and consisting of the central body f and parallel plates 11 b projecting at right angles therefrom, and means for fastening said parallel plates to the rat-trap plates, substantially as and for the purpose 'set forth.

3. A detachable foot rest for rattrap pedals having a clamp shaped to receive a rat-trap plate, and faced with rubber, and means for
