PROVISIONAL SPECIFICATION.
An Improved Brake for Velocipedes, Cabs, and other Road
Vehicles.
I, WILLIAM COLEY, of 38, Winson Green Road, Birmingham, County of Warwick
Lamp Maker, do hereby declare the nature of this invention to be as follows :-
This invention relates as hereinafter described to an improved brake for velocipedes,
cabs and other road vehicles and has for its object to provide a brake fitted with a
rotary roller for operating on the rubber tyre of a wheel, instead of the ordinary
pressure block thus greatly reducing the wear of the tyre caused by the pressure of
the metal or other solid brake block. By my improved brake the pressure on the
tyre is applied gradually and firmly thus preventing any sudden action to cause the
rider to be thrown. My invention consists essentially when applied to a bicycle in
providing the extreme end of the brake rod with a forked like end into which I fit an
anti-friction roller preferably of rubber shaped to fit partly around the wheel tyre so
as to clip the same and form a firm grip, I provide the said roller with a tubular
spindle held in position by metal plates one at each end thereof which are screwed or
rivetted to the said spindle into which I fit an ordinary spindle attaching the same to
the forked end of the brake rod by means of two nuts or other suitable means so as to
enable the roller rotating freely. I may in some cases furnish the roller with ball-
bearings so as to assist the rotary motion thereof. My improved brake is applicable
to any kind of vehicle where pneumatic or other tyres are used and may be fitted to
the ordinary brake fittings in any suitable manner.

Vehicles.
I, WILLIAM COLEY, of 38, Winson Green Road, Birmingham, in the County of
Warwick, Lamp 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 :—

tyre is applied gradually and firmly thus preventing any sudden action causing the
rider to be thrown. My invention consists essentially when applied to a bicycle in
providing the extreme end of the brake rod with a forked end, into which I fit an
anti-friction roller to fit partly around the wheel tyre so as to clip the same and form
a firm grip. I provide the said roller with a tubular spindle held in position by two
metal plates one at each end thereof screwed or rivetted to the said spindle into which
I fit an ordinary spindle attaching the same to the forked end of the brake rod by
nuts or the equivalent to enable the roller rotating freely. I may in some cases
furnish the roller with ball bearings to assist the rotary motion thereof.
My improved brake is applicable to any kind of vehicle where pneumatic or other
tyres are used and may be fitted to the ordinary brake fittings in any suitable
manner. I will proceed to describe my invention by reference to the accompanying
drawings the same letters of reference indicating similar parts throughout.
Figures 1 and 2 show respectively a front and side elevation of my improved brake
in position above the tyre of a machine.
Figures 3, 5, 6 and 7 are detail views. Figure 6 being a modification. The brake
rod F terminates into a forked end D into which is fitted the antrifriction roller A
composed of rubber or like material. The roller is provided with a tubular spindle C
shown separately at Fig. 5 being connected by two metal flanges B B screwed to fit
the ends of the tubular spindle F and connected to the roller A by pegs or
nails E as shown at Fig. 3. An ordinary spindle H also shown separately at Fig. 7
passes through the tubular spindle C2 through each end of the fork D being held
in position by screw nuts M M. Fig. 4 shows a modification in which the
ordinary ballbearings K K are let in the roller A as shown. Upon my improved
brake being applied by the ordinary brake lever the roller A takes gradual bearing
upon the tyre A and causes no sudden shock to the rider as in the use of brake-
blocks.
Having now particularly described & ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
1. A brake for velocipede wheels consisting of a roller rotating on a fixed axis so
arranged as to be operated either by a lever or the equivalent & retard & stop the
action thereof substantially as described & illustrated.
