Improvements in Brakes for Cycles or Velocipedes.
I THOMAS CROWTHER, of Fernbank Drive, Bingley, in the County of York,
Draper, do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in brakes for cycles or velocipedes, and
its object is to provide a bruke of simple construction which may be readily
applied with any suitable pressure and which will remain on when once
applied until again taken off by the rider.
"
For this purpose I arrange the brake to be applied by a cam, an eccentric or
its equivalent which may be mounted in front of the handle bar or in any other
convenient position. The periphery of the cam or its equivalent may be arranged
to bear upon the usual brake rod so as to depress it when the eccentric is turned.
A spring is provided to lift the brake rod when the cam is moved in the reverse
direction to take off the brake. A lever is fixed to or formed on the cam by
which it may be turned and the cam may be formed with serrations or notches
to engage the rod and prevent the position of the cam being changed by the
vibration of the machine.

Improvements in Brakes for Cycles or Velocipedes.
I, THOMAS CROWTHER, of Fernbank Drive, Bingley, in the County of York,
Draper, 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:-

Figure 1, in the accompanying drawing represents a front view of a portion of
a handle bar with my improvements applied to it.

is omitted in the latter figure.
The cam
Figure 4, is a similar view to Figure 1 illustrating an arrangement in which a
lever is introduced between the cam and the brake rod in order to bring the cam
and cam lever closer to the handle. Figure 5, is a plan view of the same.
The handle bar A and the brake rod B, may be of any ordinary form. In
Figures 1, 2 and 3 an upward extension C is formed on the rod guide D upon
which the cam E is pivoted by the bolt F. The edge of the cam bears upon the
top of the brake rod B and is made with serrations or notches E fitting the top
of the rod. A lever E3 projects from the cam above the handle bar and to force
the rod B down to apply the brake this lever is more or less depressed thereby
turning the cam and forcing the brake rod downwards.
In Figures 4 and 5 the cam E is pivoted by the screw F to the clip G fixed to
the handle bar A and the lever E projects below the handle A A lever II
coupled to the top of the brake rod B is pivoted by the screw J to the clip K
fixed to the handle bar and its outer end projects over the cam E. This end of
the lever has a projection H2 to engage the notches E2. It will be evident that
raising the lever 3 will depress the end of the lever I coupled to the brake rod B
and apply the brake.
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. Cycle brake applying mechanism consisting of a serrated cam or eccentric
provided with an operating lever and adapted and arranged to engage the brake
rod, substantially, as herein shown and described.
2. Cycle brake applying mechanism consisting of-a-serrated cam or eccentric
provided with an operating lever and adapted and arranged to engage a lever or
its equivalent intermediately located between said cam and the brake rod, sub-
stantially as herein shown and described.
