PEDAL FOR VELOCIPEDES.

SPECIFICATION forming part of Letters Patent No. 327,786, datedOctober 6, 1885.

Application filed August 31, 1885.

To all whom it may concern.-

Be it known that 1, CHARLES H. Games, a citizen of the United States, residing at Worcester, in the county of Vv'orcester and State of Massachusetts, have invented certain new and useful Improvements in Crank-Pedals for Bicycles; and I declare the following to be a description of my said invention, sufficiently full, clear, and exact to enable others skilled 1c in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

The object of my present invention is to pro- I 5 vide a pedal for use upon the cranks of bicycles which will give a secure hold for the sole of the boot or shoe and obviate any liability of the foot slipping on the pedal when forcing the machine, as when racing or in other performances requiring more than ordinary ex ertion of force or quickness of movement 5 also, to provide a pedal of the class named which can be manufactured with practical facility and at reasonable cost, and that will be serv- 2 5 iceable, efficient, and durable for use.

My invention consists in a pedal constructed with spur-sections or toothed washers introduced between plain supporting-sections or rubber cylinders on the foot-bars, said Wash ers projecting slightly above the surface of the intervening section to engage the sole of the boot or shoe, as more fully hereinafter eX- plained.

In the drawings, Figure 1 is a plan view of one of my improved pedals for bicycles. Fig.

2 is a vertical section at line at m, Fig. 1. Fig.

3 shows side and section of the spurred washer, and Figs. 4 and 5 show modifications in the form of the spurred washer.

In reference to parts, A denotes the crank arm of the bicycle, B the center supporting sleeve that turns on the crank-pin B, and C the cross-bars or side plates of the pedal, all of which parts maybe of any suitable form or 5 of ordinary well-known construction@ The supports or bearing-bars upon which the foot rests, are in accordance with my invention constructed in the following manner, viz: The rods D D, which extend from one of the plates 0 to the other, are made rectangular, (or of other irregular section,) with round ends that pass through said plates, and are fit- Serial No. 175,707. (No model.)

ted with clamping devices or nuts ddfor clamping the parts firmly together. Upon these rods D are arranged a number of plain tubular cylindrical sections, E, having supported between the ends thereof thin metal washers I, the edges of which are provided with teeth or spurs t, that project beyond the surface of the sections, thus making a foot-bar having annular rows of projections that give a grip for the sole of the shoe, so that it cannot slip on the pedal.

The sections E are preferably formed of rubber, so as to be elastic; but wood, leather, or other suitable material may be used, if desired. The spurred washers are made of metal preferably of sheet-steelthree thirty-seconds of an inch (more or less) in thickness, punched out in proper form, with the spurs or teeth t slightly blunted at the ends, and with an eye or hole, 6, formed through their center to fit the form of the rod D, so as to be non-rotative thereon.

The series of sections E and washers I are made of such size as to fill the space and be ,firmly clamped between the side plates, C,

when the nuts (1 are screwed up, so that the disks or washers will be supported laterally by the sections E in the manner illustrated.

The spur-washers are preferably made circular; but, if desired, could be of rectangular form, as in Fig. 5; or they can be made, as in Fig. 4, with spurs or points on one side only, the other side being plain, as at m. This latter shape will produce a pedal that has spurs one side to be used as a racing-pedal, and a plain bearing when used the other side up for ordinary running.

The rods D may be square, as in Fig. 3, or round with fins at its side, as in Fig. 4, or hexagonal, as in Fig. 5, or of other equivalent shape that will hold the spurred disks in place. In case the points become worn off the washer I can be removed and replaced at one quarterturn in relation to the rod D. This will bring a new set of points into wearing position.

The relative lengths of the plain sections E can be varied from that herein shown, so that the washers will stand more or less near together, as desired, and a greater or less number of said washers I can be used 011 the bars. If desired, the elastic sections E might be made of nearly the same diameter as the wash ers, so that the spurs would not project to any great extent beyond their surface, except when pressure was brought to bear on the elastic sections E sufficient to compress them away from said points. The sections E may be round or other shape to correspond with the style of pedal, and their surface may be smooth or corrugated, as preferred.

With this improved pedal the spurs or an nular rows of points are presented to the sole of the shoe in such manner that a'secure hold is obtained, so that the footcannot slip in any direction on the pedal, while at the same time the removal or lifting of the foot from the pedal is in no way interfered with. This will be readily appreciated by any person conversant with the operation of bicycles in racing and exhibition performances.

What I claim as of my invention, and desire to secure by Letters Patent, is

CHARLES H. GATES.
