An Improved Brake for Cycles, Tricycles, and the like.
I, JAMES STALEY, R.P.C. Brailes in the County of Warwick Hydraulic and Sanitary
Engineer do hereby declare the nature of this invention to be as follows :-
The Improved brake for cycles tricycles and the like has for its object to remove
the brake power from action on pneumatic or other tyres to a projecting rim attached
on to the inside of the crank axle wheel by a shoe made to press on the inside of the
said projecting rim, the said pressure is put on by a lever attached there two & with
the handle bar.

JAMES STALEY,
Brailes, Warwickshire,
I, JAMES STALEY, R.P.C., of Brailes in the County of Warwick, Hydraulic and
Sanitary Engineer, do hereby declare the nature of this invention and in what manner
the same is to be performed to he particularly described and ascertained in and by
the following statement:-
This invention relates to an improved brake for oycles and consists essentially of a
shoc adapted to be pressed against the inner edge of the rim of the sprocket wheel
nounted on the pedal crank axle, the object being to produce an efficient and light
brake.
I will now more particularly describe my invention making reference to the accom-
panying drawing in which
Fig. 1 is a broken view in side elevation showing the application of my brake-by
way of example to a rear driving safety bicycle and
Fig. 2 is a broken detail view in section on line X-X of Figure 1.
Throughout both views similar parts are marked with like letters of reference.
The usual sprocket wheel A mounted on the pedal crank axle X is so constructed as
to allow a bearing surface a to be provided on its inner edge or side. A shoe B of any
suitable length and section but preferably of the section shown in Figure 2 is provided
on its periphery or edge with a rubber or leather face b which is adapted to engage
with the bearing surface a of the sprocket wheel A when pressed into contact there-
with. The shoe B is carried and adapted to be operated by a lever C which is pivoted
at e to a snug D carried by the member X of the frame. The lever C may be of
any convenient shape or form depending greatly on the way in which it is to be
operated, the form shown on the drawing being particularly applicable when it is to

page_text: be operated by a rod or cord in tension carried up along the member X¹ to the
handle bar where it may terminate or be attached to any suitable form of operating
device.
A spring may be arranged in any suitable position in such a manner as to keep the
face of the shoe B from engaging with the surface a of the wheel A in its normal
or "off" position.
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 :-
1. A brake for cycles and the like consisting essentially of a shoe attached or pivotted
to the frame and adapted to be pressed into ongagement with a surface or edge formed
on the sprocket wheel mounted on the pedal crank axle.
2. A brake for cycles and the like constructed, arranged and adapted to be operated
substantially as herein before described and shown.
