Improvements in or connected with Brakes for Velocipedes and
other similar Vehicles.
We CHARLES HART and EDWARD JULIANS HART both of The Royal Hotel
Great Yarmouth Gentlemen, 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 :-
Our invention relates to improvements in or connected with brakes, more
particularly intended for velocipedes, and has for its object to provide and arrange
a brake in such a manner that it shall not come into contact with the tyre of the
wheel as has hitherto been the case, but shall take effect upon suitably shaped
side projections formed on the rim of the wheel for that purpose, while it is of
simple construction and enables the rider to have thorough control over the
machine.
In carrying our invention into practical effect, the rim of the wheel is provided
with two projecting lips or flanges one on each side, while the end of the brake
rod is formed with, or carries a forked piece, the arms of which enter or engage
with the said projecting lips or flanges formed on the rim of the wheel, when
pressure is applied by means of the usual brake handle of pressure rod. By this
means all pressure upon the tyre itself is avoided and consequently the life of the
said tyre is considerably prolonged.
In order that our invention may be more fully understood, we will now proceed
to describe same with reference to the accompanying drawings, in which
Fig. 1 is a cross section through the top of a tyre and rim with the brake fork
in elevation and Fig. 2 a side elevation of same.
Fig. 3 is a cross section through a rim formed according to this invention
showing the lips or flanges and
Fig. 4 is a modification of the brake fork hereinafter more fully described.
According to this invention the end of the brake rod a is formed with or
carries a forked piece p the ends d, d', of which enter or bear upon the projecting
lips or flanges ff', formed upon the rim r of the wheel, when pressure is applied
by means of a brake handle or lever of ordinary construction.
In order to prevent any noise that might be produced if the metal of the brake
fork came into contact with the metal of the flanges and in order to give the fork a
better frictional grip upon same, the ends of it may be furnished as shown at
Fig. 4, with a covering or strip of india-rubber, leather or other suitable material i,
either turned round same as shown at a¹ and secured by means of small pins,
screws, cement or in any other suitable manner, or the ends of the forked arms
may be grooved as shown at b and the leather, india-rubber or the like let into
same, or it may be attached in any other manner that may be found more con-
venient, and further where leather, india-rubber or the like is not employed, the
ends of the fork, or the grooves in the rim or both may be roughened or serrated
in order to afford a better grip.
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 :-
1. The improvements in or connected with brakes for velocipedes and other
similar vehicles consisting of the rod a having forked piece the ends d, d¹, of

page_text: which may be furnished with leather, india-rubber, or other suitable material i or
not as desired, in combination with a rim r having lips or flanges f, f', substantially
as herein described and shown and for the purposes specified.
2. The improvements in or connected with brakes for velocipedes and other
similar vehicles, substantially as herein described and shown and for the purposes
specified.
