page_text: I, HARRY HUGH EVANS, of 61, Swansea Terrace, Cardiff, in the County of
Glamorgan, Fitters' Assistant, do hereby declare the nature of this invention to
be as follows:-
The object of this invention is to provide a more effective method of retarding
the motion of bicycles, than has hitherto been employed.
The invention can be applied to almost any kind of bicycle, either of the lady's
or gentleman's type.
My invention consists of a small apparatus that can be very quickly attached
to the machine and can be supplied complete, so that by the mere application of
a pair of bolts or studs and nuts, it can be attached to the machine in a very brief
space of time, and as quickly removed when so desired.
My apparatus consists of a clamp or small bracket which is preferably clipped
around the steering fork of the bicycle, the usual form of fork having a convenient
round neck between the ridged plates or collars situated at the top end of the fork,
and around this my bracket may be clipped and held firmly by means of the
screws or studs before mentioned.
This bracket has a jaw projecting slightly downwards and to the rear of the
steering fork, engaging with this jaw, is a horse-shoe shaped claw, one end being
pivoted in the jaw which is fixed to the steering fork.
'
This claw is capable of a vertical movement only and is held normally upwards
away from the tyre by means of a suitable spring, one end of which is attached
to the claw and the other to a lug formed upon the top part of the fixed jaw.
Between the extreme ends of the claw transversely is mounted a roller.
To the sides of the claw I attach outwardly projecting arms or foot-rests which
are roughened upon their surface, these being for the purpose of receiving the.
thrust from the rider's feet.
'Pressure with the foot or feet upon these projecting pins presses down the
brake roller against the pull of the spring on to the tyre, consequently applies.
the brake. On removing the feet the spring returns the roller to its normal
position.
The roller may be made of india-rubber or any other material, and is prefer-
ably made with the middle convex, with a convex ridge at each end.
Upon the ends of the roller, I prefer placing metallic washers, so that the sides
of the washers shall come into contact with the inside surfaces of the claw. These
washers have a tubular projection upon one side which enters the end of the.
roller, and the rollers are preferably secured to the washers and tubular ends by
an adhesive material or they may be left free if necessary or desired.
A small lug may be formed upon the jaw for attaching a mud-guard, if,
required.

page_text: Improvements in Brakes for Cycles.
I, HARRY HUGH EVANS, of 61, Swansea Terrace, Cardiff, in the County of
Glamorgan; Fitters' Assistant, 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 a more effective method of retarding
the motion of cycles, than has hitherto been employed.
:
The invention can be applied to almost any kind of cycle, either of the lady's
or gentleman's type.
I will now proceed to describe my invention, as applied to a bicycle, with the
aid of the accompanying drawings, in which:-
Figure 1 represents in side elevation the front portion of a bicycle fitted with
my improved brake.
Figure 2 is a side elevation of the brake itself shown detached and drawn to
a larger scale.
Figure 3 is a plan of the brake shown in Figure 2.
Figure 4 is a sectional plan of the brake the section being taken through the
.roller.
Figure 5 is a transverse section through the roller bush and spindle.
Like reference letters denote the same parts throughout.
My invention consists of a small apparatus that can be very quickly attached
to the machine and can be supplied complete, so that by the mere application of
a pair of bolts or studs and nuts, it can be attached to the machine in a very
brief space of time, and as quickly removed when so desired.
My brake apparatus consists of a clamp or small bracket a which is preferably
clipped around the steering fork 6 of the bicycle, and fixed by means of the bolts
or studs d, before mentioned; the usual form of fork having a convenient
round neck between the ridged plates or collars c, c¹ situated at the top end of the
fork, and around this my bracket may be clipped.
This clip may be made in any convenient form so as to adapt itself to the shape
of the various fork heads in use, and I therefore do not confine myself to the
method of attachment herein shown, as it is obvious that this form of clip can
only be used on forks that have a round part at the head between the collars
€,
c¹.
This bracket a has a jaw e projecting a short distance downwards at the rear
of the steering fork. Engaging with this jaw, is a horseshoe-shaped claw f, one
end g of which is pivoted in the jaw e which is fixed to the steering fork.
This claw is capable of vertical movement only on the hinge pin h and is held.
normally upwards away from the tyre by means of a suitable spring i one end
of which is attached to the claw fat f' and the other to a lug / formed upon the
top part of the fixed jaw e.
Between the extreme ends of the claw f, transversely, is mounted a roller r
fixed firmly on sleeves n which are rotatably mounted on the spindle p secured.
between the outer ends of the claw by the nut p¹.
This roller may be made of india-rubber or any other material, and is prefer-
ably made with the middle portion convexed as shown and with a convex ridge
or flange m at each end.
Upon the ends of the roller, I prefer placing metallic washers n, so that the
sides of the washers shall come into contact with the inside surfaces of the claw f.
These washers have a tubular projection n¹ upon one side which enters the end
of the roller and the latter is preferably secured to the washers and tubular exten-
4

page_text: sions thereof by an adhesive material, but they may be left free if necessary or
desired. The points n² of these bushes or cylindrical sleeves n' are preferably
conically formed in order that when the roller r is pressed inwards it will have
the effect of forcing the bushes outwards or asunder causing the flanges or
washers n to rub with more or less friction against the inner faces of the claw or
frame f, thus assisting in retarding the motion of the road-wheel.
To the sides of the claw f are rigidly attached outwardly-projecting arms or
foot-rests which are preferably roughened, serrated or toothed upon their sur-
face, as shown at k, these being for the purpose of receiving the thrust from the
rider's feet when applying the brake.
A small lug m may be formed upon the jaw for attaching a mud-guard if
required.
-
Pressure with the foot or feet upon these projecting pins presses down the brake
roller against the pull of the spring i, on to the tyre, and consequently applies
the brake. On removing the feet the spring returns the roller to its normal
position away from the tyre.
Having now particularly described and 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 a cycle wheel, consisting of a frame carrying a roller at one
end and being hinged or pivoted on a horizontal pin at its other end to a clamp
adapted to be fastened rigidly upon the steering fork of the road-wheel, a spring
connecting said frame with said clamp, and foot-rests connected rigidly to the
hinged frame, substantially as described and set forth.
2. A brake for a cycle wheel, consisting of a frame carrying a roller at one end
and being hinged or pivoted at the other end to a clamp adapted to be fastened
rigidly upon the steering fork of the road-wheel, a spring connecting said frame
with said clamp, foot-rests connected rigidly to the hinged frame and means for
attaching a mud-guard to the clamp, substantially as described and set forth.
3. The combination with a steering fork of a cycle, of the brake consisting
of a clamp rigidly secured to the said fork, a frame hinged to said clamp, an
anti-friction roller mounted in said frame, a spring connecting the frame with
the clamp, foot-rests on the frame and means on the clamp for attaching a mud-
guard, all combined and co-operating substantially as described and set forth.
