Description

ALBERT WALSTEAD CHESTERMAN, OF SPARKHILL, ENGLAND.
CYCLE PEDAL-PLATE.
Specification of Letters Patent. Application filed June 6,1905. Serial No. 263,963.
Patented May 8, 1906.
I To all whom it may concern:
Be it known that I, ALBERT WALSTEAD CHESTERMAN, tool-maker, a subject of His Majesty the King of Great Britain and Ire.- land, residing at 6 Durham road, Sparkhill, Birmingham, England, have invented new and useful Improvements in Cycle Pedal- Ilates, of which the following is a specification. a
This invention has reference to cycle pedalplates which are commonly known as rattrap and are usually made with a row of teeth on each edge. In course of time, however, these teeth wear off and then in order to obtain a firm grip of the foot on the pedal it is necessary to use toe-clips, which, as is well known, are troublesome and dangerous. The object of this invention is to provide a pedalplate with the teeth so constructed that they will not wear off, other parts of the pedal.
My invention is applicable to all kinds of pedal-plates irrespective of the particular shape of the pedal with which they are used.
I will describe my invention by referring to the accompanying drawings, on which- Figure 1 is a general view of a rat-trap cycle-pedal with the edal-plates constructed in accordance with t 's invention. Fig. 2 is a side elevation of one of the pedal-plates separately. Fig. 3 is a cross-section of the same on line X X of Fig. 2, and Fig. 4 is a lan of the same.
The same reference-letters indicate the same or corresponding parts in all the figures.
In carrying out this invention each of the cycle pedal-plates a a are cut out of sheetsteel or other suitable sheet metal with one, two, three, or more half-round lugs or projections b, which are turned at ri ht angles to the face of the plate a, and in hoIes which are drilled or pierced in these lugs or projections b I insert hard-steel spikes c, which are pointed but will last as long as the and of conical form and stand outwardly, as shown on my drawings, so as to stick into the sole of the cyclists boot or shoe. As these spikes are made of a pointed conical form, as shown, they stick into the sole of the cyclists boot or shoe immediately it is placed on the pedal and render it impossible for the sole to slip on the pedal, thus effectually preventing the s ikes from wearing away.
I d that two spikes at a short distance apart on one edge of the pedal-plate and one central spike on the opposite edge of the same, as shown on my drawings, answers well in practice, as the two spikes on one pedal-plate will then be under the wide part of the riders boot or shoe and the one spike of the other pedal-plate will be under the toe part of his boot or shoe. It is to be understood, however, that more or less than three spikes on each pedal-plate may be used, if desired. I make no claim in respect of any part of the pedal except the pedal-plates constructed with the conical as above described. The spikes are secured in the holes in the lugs 12 by any convenient means, as by each spike being made with a smaller shank d, Fig. 3, which is driven into the hole in the lug b.
What I claim as my invention, and desire to secure by Letters Patent, is-
A cycle pedal-plate provided at its edges with lugs or projections turned at right angles to the plate and with hard-steel conical spikes fixed in holes in said lugs to engage in the sole of the cyclists boot or shoe, substantially as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
ALBERT WA'LSTEAD CHESTERMAN.
