PROVISIONAL SPECIFICATION.
Improvements in Pedals for Velocipedes.
We, JAMES EDGAR BAXTER of Leyland, near Preston, in the County of
Lancashire, Manager, and PHILIP LOUIS RENOUr of Stoke near Coventry, in
the County of Warwick, Manager do hereby declare the nature of this invention
to be as follows:-
The object of this invention is to provide for sufficient cushion between the rigid
frame of the pedal and the shoe of the rider, and to prevent the shoe from slipping
over the pedal when exerting pressure. For this purpose the pedal stretchers are
provided with soft rubber, and sometimes hold pairs of inflated balls or tubes.
Sometimes this rubber is provided with a series of sharp steel projections which
will effectually prevent any slipping of the shoe. These are preferably formed by
piercing, stamping, punching, or otherwise shaping sheet metal into a zigzag or
other suitable shape, the pointed edges of the metal being turned upwards, and the
central part being moulded or otherwise fixed to the pedal rubbers.
The rubbers may be per orated or recessed so as to be lightened and form
cushioning air chambers.
Sometimes we use detachable plates or shells furnished with two or more rows of
teeth, and mounted each on one pedal bar only, so as to adapt themselves readily
to the shape of the sole when under pressure.

COMPLETE SPECIFICATION.
Improvements in Pedals for Velocipedes.
We, JAMES EDGAR BAXTER, of Leyland, near Preston, in the County of
Lancashire, Manager, and PHILIP LOUIS RENOUF, of Stoke near Coventry in the
County of Warwick, Manager, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of this invention is to provide for sufficient cushion between the rigid
frame of the pedal and the shoe of the rider, and to prevent the shoe from slipping
over the pedal when exerting pressure.
In order that our invention may be clearly understood we have annexed the
accompanying sheet of drawings.
The first part of our invention is illustrated at Fig. 1 which is a transverse
section of a pedal stretcher A provided with inflated balls or tubes B, B'. These
balls or tubes B, B' are lined with canvas a, a¹ and are filled with air under
pressure, the said canvas a, a¹ restraining the air chamber from undue expansion.
The air tubes B B' which take the place of the ordinary pedal rubbers are secured
onto the stretchers A by any suitable means and the said stretchers A may be
rivetted, screwed or bolted to the ordinary side plates of a pedal.
The second part of our invention is illustrated at Fig. 2 which is a longitudinal
view of a rubber pedal bar C provided with a series of sharp steel projections b, bl
for effectually preventing any slipping of the shoe. These projections bare
preferably formed by piercing, stamping, punching or otherwise shaping sheet metal
into a zigzag or other suitable shape, the pointed edges of the metal being turned
upwards (as clearly shewn at Fig. 3 which is a cross section of Fig. 2) and the

page_text: central part being moulded with or otherwise fixed to the pedal rubber so that the
Faid projections b, are isolated from the stretches of the pedal by a cushion
layer of rubber or other elastic or soft material. The rubber bars C may be
perforated or recessed as at c so as to be lightened and form cushioning air
chambers.
We may when desired use detachable plates or shells furnished with two or more
rows of teeth, and mounted each on one pedal bar only so as to adapt themselves
readily to the shape of the sole when under pressure.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
:-
Firstly-A pedal bar formed by a cushioning chamber containing air under
compression and restrained from undue expansion by canvas substantially as
described.
Secondly-Inserting a serrated metal plate or plates or other projections in a
pedal bar in such a manner that they are isolated from the stretchers by a cushioning
layer of rubber or other elastic or soft material.
Thirdly-A pedal rubber provided with metal projections in the manner and
for the purpose substantially as shewn and described.
