An Improvement applicable to the Pedals of Bicycles and other
Velocipedes.
1 CHARLES ALBERT CARR of Spring Street Post Office Bury in the Countyot
of Lancaster Shuttle Maker, do hereby declare the nature of this invention to be as
follows:-
This invention is applicable to the pedals of bicycles, tricycles, and other
velocipedes driven by the foot and the objects of the invention are to give a better
grip of the boot or shoe on the india rubber tread" of the pedal, to prevent the
same from becoming worn smooth which occasions slipping of the foot, and also to
renew the surface of the same when worn without having to renew the india rubber
tread itself.
The invention consists principally of a light steel or other metal plate made to
fit onto the face and around the edges of the india rubber tread "and roughened
on the working surface either by having holes pricked through from the back so
as to leave rough burrs like a bread grater, or made rough on the surface like a file,
or otherwise roughened so as to give a firm hold or grip to the shoe or boot of the
rider and prevent slipping of the foot.
These roughened plates may be applied to one or more surfaces of the india
rubber tread and bent round the edges so as to take a firm hold of the same or
they may be made like a square tube so as entirely to surround the india rubber.
tread and present four roughened surfaces to the foot."
If made to fit properly and closely to the form of the india rubber with slight
compression, they will not require any further fastening, but if preferred they may
be further secured by any suitable incans such for example as pins springs or clips,
or the ends may be bent over the ends of the "treads" and provided with a hole
through which the pedal pins pass.

COMPLETE SPECIFICATION.
An Improvement applicable to the Pedals of Bicycles and other
Velocipedes.
I CHARLES ALBERT CARR of Spring Street Post Office Bury in the County
of Lancaster, Shuttle Maker, 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: —
This invention is applicable to the pedals of bicycles, tricycles, and other
velocipedes driven by the foot and the objects of the invention are to give a better
grip of the boot or shoe on the india rubber or other elastic "tread" of the pedal,
to prevent the same from becoming worn smooth which occasions slipping of the
foot and also to renew the surface of the same when worn without having to renew
the india rubber or other tread itself.
In order that my invention may be clearly understood I have annexed hereto a
sheet of drawings illustrative thereof and have marked the same with figures and
letters of reference corresponding with those in the following description.
Fig. 1 is an elevation and Fig. 2 a plan view of one of my metal plates adapted
to the ordinary pedal of a bicycle.

page_text: Fig. 3 shews a sectional elevation of a pedal with the said plate applied thereto.
Figs. 4, 5 and 6 illustrate modifications hereafter described.
The invention consists principally of a light steel or other metal plate a
(Figs. 1 and 2) made to fit on the face and round the edges of the india rubber or
other tread and roughened on the working surface either by having holes
pricked through from the back so as to leave rough burrs like a bread grater as
shown or made rough on the surface like a file, or otherwise roughened so as to
give a firm hold or grip to the shoe or boot of the rider and prevent slipping of the
foot.
These roughened plates a may be applied to one or more surfaces of the india
rubber or other "tread" c and bent round or over the edges so as to take a firm
hold of the same (see Fig. 3) or they may be made like a square or rectangular
tube so as entirely to surround the india rubber or other tread and present four
roughened surfaces to the foot. I prefer to make the plate a curved slightly as
shewn at Fig. 1 so that when applied it will be sprung over the india rubber tread c
at each end, and assume a flat form and will adhere firmly thereto.
If made to fit properly and closely to the form of the india rubber with slight
compression, they will not require any further fastening, but if preferred they may
be further secured, by any suitable means such for example as pins springs or clips,
or the ends may be bent over the ends of the "treads and provided with a hole
through which the pedal pins pass.
In some cases I use four pedal pins d as shewn at Figs. 4, 5 and 6 and then
have a very thin covering of india rubber c (or none at all) over them.
A plate
may be sprung over the upper pair (or both pairs) of pins d as shewn at Fig. 6 or
the said plate or plates a may be so curled or bent at the ends a¹ see Fig. 5 that
the pins d must be passed through after the plate or plates a have been put in place,
and in this case the pins are fixed in position by nuts d¹ (see Fig. 4) instead of
rivet heads which can be used for pedals made as shewn on Fig. 6.
These modifications will form pedals of the rat trap type the usual serrated
plates being dispensed with and my improved appliance substituted therefor as
shewn.
It will be evident that although I have shewn the plate a as broad as the
ordinary pedal tread, it may be narrower or two narrow plates may be used side by
side.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is
The improvement applicable to the pedals of bicycles consisting of a roughened
plate or plates fastened over or round the tread of the pedal substantially as
herein before described and illustrated by the annexed drawing.
