I, ALBERT ERNEST JENKS, Manufacturer, Clyde House, Heath Town, Nr.
Wolverhampton, do hereby declare the nature of this invention to be as follows:-
The object of the invention is to provide a brake-guide which shall not require
a separate spring to keep the brake out of contact with the tyre.
This I do by making a flat steel spring of suitable length having lugs or ears at
cach end turned up and pierced with the necessary holes. One end of the spring
is secured to the plunger by means of a pin or rivet passed through the holes in
the ears at that end, and through the brake plunger which works between the
said ears.
The other end is secured either to the back part of the crown or prefer-
ably to a clip or band passing round the centre tube between the crown plates
having suitable lugs or ears to be secured by pins and nuts to the ears of the spring
as before mentioned. The spring is set preferably so as to have when at rest a
bearing against the underside of the crown. When in action the spring gives
way so as to allow of any pressure being put upon the brake and as the pressure is
withdrawn lifts up the brake until the spring is at rest against the crown.

A Combined Brake Guide and Spring for Cycles and similar Vehicles.
I, ALBERT ERNEST JENKS, of Clyde House, Heath Town, near Wolverhampton,
Manufacturer, 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 the invention is to provide a brake guide for a cycle or similar
vehicle which shall not require a separate spring to normally keep the brake out
of contact with the tyre.
,
This object is effected, according to this invention, by suitably constructing a
spring for the purpose and utilising it both as a brake guide and as a spring which
automatically acts in moving back the brake block from the tyre as the pressure
upon the block is released and which normally keeps the brake out of contact with
the tyre.
One end of the spring is fixed to the front fork, conveniently by fixing it to
the ears of a clip which encircles the barrel portion of the crown, or by fixing it
to a lug which projects at the back of the lower plate or flange of the crown; and
its other end is connected with the brake, conveniently to the brake plunger.

page_text: In order that the invention may be clearly understood, I will proceed to
describe, by way of example, practical applications of the same which are illus-
trated on the accompanying drawings.
Figure 1 illustrates, in perspective view, the spring and its connection with
a clip by which it is to be attached to a front fork, and shews also its connection
with the brake plunger. In this view, the parts only are shewn which are to be
connected with the cycle. Figure 2 illustrates, in side elevation, the modification
of the invention in which the hinder end of the spring is fixed to a lug which
projects from the lower plate or flange of the crown.
Referring first to the parts shewn by figure 1:
A is the clip which when fixed in place upon the machine surrounds the barrel
portion or tube of the crown of the front fork. B is the spring which is formed
at its hinder end with ears through which the pins c pass which are used in
fixing the clip in place. The pins e thus securely tighten the ears 6 of the spring
against the ears a of the clip, and also, of course, tighten the clip in place. The
ears of the spring stand up some distance, as shewn, above the spring plate or
strip to give them sufficient elasticity to ensure that they will be sprung in tightly
against the ears a as the pins c are tightened up. The forward end of the spring B
has formed therewith ears, as shewn; and this end is connected with the brake
plunger C by means of a pine which passes through the ears and through
the plunger. It will now be seen that the spring B acts both as a guide to the
plunger and as a spring to normally keep the brake block 1) clear of the tyre.
The spring B is set, preferably, so that it normally presses up against the under-
side of the fork crown which forms a stop to the upward movement of the spring
and forms consequently a stop also to the upward movement of the brake plunger.
The mud-guard fastener E may be fixed to the clip in the usual manner, as shewn.
Referring now to figure 2, which shews only as much of the modification as
differs from the arrangement shewn by figure 1:
The lower plate or flange f of the fork crown F is formed with a backward lug g,
and the hinder end of the spring B is fixed to this lug by means of a pin or pins h.
If a single pin only is used it should be of a shape in section which will prevent
the spring turning sideways. If two pins are used, they may be side by side, or
one behind the other.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim, is:
:―
1. A combined brake guide and spring, for a cycle or similar vehicle, which auto-
matically operates to move the brake clear of the tyre as the pressure upon the
brake block is released, and normally keeps the brake clear of the tyre, substantially
as described.
2. A combined brake guide and spring, for a cycle or similar vehicle, arranged
to pass between the underside of the fork crown and the top of the wheel tyre,
substantially as described.
3. A combined brake guide and spring, for a cycle or similar vehicle, formed at
its hinder end with ears for connection with a clip and formed at its forward end
for connection with the brake, substantially as described and shewn by figure 1.
4. A combined brake guide and spring, for a cycle or similar vehicle, formed at
its hinder end for connection direct with the fork crown, and formed at its forward
end for connection with the brake, substantially as described and shewn by figure 2.
Dated this 24th day of November 1897.
