FRANK SVEETLYAND, OF ANGOLA, NEW YORK.

BICYCLE-PEDAL.

SPECIFICATION forming part of Letters Patent No. 473,030, dated April 19, 1892.

` Application filed February 10, 1892. Serial No. 420,995. (No model.)

To aZZ whom it may con/cern,.-

Be it known that I, FRANK SwEETLAND, a citizen of the United States, residing at Angola, in the county of Erie and State of New York, have invented a new and useful Bicycle-Pedal, of which the following is a specification.

My invention relates to improvements in pedals for bicycles, tricycles, and the like; and the objects in view are to provide apedal that will provide a good footing or purchase for the rider, that will be light and adapted to all the various machines being manufactured, and whose rubber portions may be readily removed and replaced when worn.

Vith the above objects in view the invention consists in certainfeatures of construction hereinafterspeciiied,and particularly pointed out in the claims. n

Referring to the drawings, Figure l is a perspective view of a pedal embodying my invention. Fig. 2 is a longitudinal section. Fig. 3 is a transverse section. Fig. 4 is a detail of the box or frame. Fig. 5 is a detail of one of the clamping-plates.

Like numerals of reference indicate like parts in all the figures of the drawings.

`l denotes the usual crank, from which projects the crank-pin 2, and the same may be tapered or not, or adapted for ball-bearings, as desired.

3 designates a box or frame formed of metal and rectangular in cross-section, the same being preferably oblong in plan. This box may have its upper side or both of its sides flat, as shown in full lines, or concave, as indicated by dotted lines. The box is hollow in order to secure lightness, and has passed longitudinally through its center a thimble or bearing-sleeve 4, which fits and is adapted to rotate upon the pin 2 between the shoulders 5, with which the pin is provided near its inner end or butt. At its ends the box is provided with oppositely-curved guards 6. At opposite sides of the box rubber pads 7 are appliedfthe same having their outer surfaces corrugated or otherwise roughened, as is usual. These pads, if the box is plain, are preferably counter-sunken toward their centers, or, in other words, thickened near their edges, as shown; though if the box is curved,

as shown by dotted lines in Fig. 3, the pads will be flat or plain. The pads are slightly wider than the box, so that their edges extend down slightly over the sides of the box, and the pads may be cemented in their positions, as will be obvious. To the opposite sides of the box clamping-plates 8 are applied, the same equaling in length the pads and the box and havingY their opposite longitudinal edges inwardly bent to form clamping-flanges 9. These flanges take between the corrugations of the pads or may be sunken into the soft rubber, from which they are made, through the medium of pairs of screws 10, passed through openings in the clampinglplates, in which the heads of the screws are countersunk, and .into threaded perforations 11, formed in the box. Thus the edges of the pads are left exposed, and yet the pads them- 7o selves-securely clamped in proper position.

From this description it will be seen thatI provide a pedal designed for use upon bicycles of the various styles as well as upon tricycles, the pedals being so formed as to t the ball of the foot, providing a secure purchase throughout the width of the pedal, and

insuring freedom of motion for the foot of the operator when driving the cranks. As will be obvious, by simply removingthe clamping-plates 8 new pads may be substituted for those Worn, and when in position slipping of the rubber will be avoided. It Will be seen that the pedal is constructed of very few parts, all of which are light and simple and well calculated for the strains to which they are subjected during riding.

Having described my invention, what I claim is Y Y l. In a pedal, the combination, with the crank and its pin, of a hollow box mounted loosely on the pin, opposite independent rubber pads mounted at opposite sides of the box, clamping-plates overlapping the edges of the pads, and screws passed through thel plates and into the edges of the box, substantially as specified.

2. In a pedal, the combination, with the crank and 'its pin, of a hollow box mounted revolnbly upon the latter, oppositeindependent rubber pads concaved and applied to the opposite sides of the box, opposite clampingedges inwardly turned to engage the pads,` and screws passed through the plates andinto the edges of the box, substantially as speeied.

In testimony that I claim the foregoing as t 5 my own I have hereto affixed my signature in the presence of two witnesses.

FRANK swEE'rLAND.
