I, WILLIAM BAUCKHAM, of 1, Grove Villas, East India Road, Poplar, in the
County of London, Shipwright, do hereby declare the nature of this invention to
be as follows:
My invention relates to brakes for bicycles and other velocipedes and to that
kind of brake known as a band brake.
According to my invention instead of a hand of spring steel I make use of a
cord (preferably made of wire) which is passed around a suitably grooved wheel
and which is at one end secured to some fixed point whilst the other end is passed
under a guide pulley fixed near the said fixed end of the cord and then led to the
lever or other device for applying the said brake.
In practice the grooved wheel over which the cord passes is mounted on the
pedal axle, and it may advantageously be formed in one piece with the chain wheel
thereon and the cord which is at one end attached to the frame is at its other end
attached to a lever or the like on the handle bar so that the movement of the
said lever in the required direction serves to tighten the cord around the grooved
pulley.
Instead of fixing the grooved pulley to the pedal axle it may be fixed to the
driving wheel or upon an independent axle.
Improvements in Brakes for Cycles.
I, WILLIAM BAUCKHAM, of 1, Grove Villas, East India Road, Poplar, in the
County of London, Shipwright, 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:-
-
My invention relates to brakes for bicycles and other velocipedes and to that
kind of brake known as a band brake.
According to my invention, instead of a band of spring steel I make use of a
cord (preferably made of wire) which is passed around a suitably grooved wheel
and which is at one end secured to some fixed point whilst the other end is passed
under a guide pulley or its equivalent fixed near the said fixed end of the cord,
and then led to the lever or other device for applying the said brake.

page_text: In practice the grooved wheel over which the cord passes is mounted on the
pedal axle, and it may advantageously be formed in one piece with the chain wheel
thereon and the cord, which is at one end attached to the frame, is at its other end
attached to a lever or the like on the handle bar so that the movement of the
said lever in the required direction serves to tighten the cord around the grooved
pulley.
In the accompanying drawings,
Figure 1 is a side elevation of a bicycle having a brake made according to my
invention applied thereto :
Figure 2 is a front elevation of the steering head of the bicycle shewing the
brake lever and cord:
Figure 3 is a section on the line 3-3 Figure 1 looking in the direction of the
arrow in the said figure; and,
Figure 4 is a section on the line 4-4 Figure 2:
Figures 2, 3 and 4 are drawn to a larger scale than Figure 1.
a is the handle bar of the bicycle, 6 the steering head, c the bottom tube, d the
bottom bracket, e the chain wheel and f,f the two cranks mounted upon the crank
axle g which is supported in the bottom bracket; all these parts are of ordinary
construction.
h is my cord which, as above mentioned, is preferably made of wire, and i is the
grooved wheel which is preferably, as is shown in the drawing, rigidly secured to
or made in one with, the chain wheel e. One end of the cord his formed with
an eye which is passed over the end of a pin j fitted into a projecting arm ¹
bolted to the bottom tube c of the bicycle frame as shewn in Figures 1 and 3.
After passing around the grooved wheel the cord is passed through a stirrup or the
like k which is also secured to the pin ; and is then passed upwards through a
guide secured to the steering head of the bicycle, the said guide being pro-
vided with a pulley over which the cord passes, thence over a second guide
pulley m mounted in a clip m¹ secured to the handle bar a and thence to an eye n
formed in a screw n which is screwed into a lug o formed upon the brake lever p
pivoted at p to the usual clip q. One arm of the lever p is adapted to be
manipulated by the rider in the usual manner, whilst the other arm is forked at
its end as shown at 7 and engages with the cord h as shewn in Figure 2, so that
when the rider pulls the lever upwards in the usual manner the forked end of
the lever tightens the cord h upon the grooved wheel thereby braking the chain
wheel.
The brake can be regulated by adjusting the screw n¹ in the lug o.
Instead of fixing the grooved pulley to the pedal axle it may be fixed to the
driving wheel or upon an independent axle.
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 cycle brake comprising a cord (preferably made of wire) which passes
around a grooved wheel, one end of the said cord being secured to a fixed point
whilst the other passes under a guide pulley or its equivalent fixed near the said
fixed point and is then led to a lever or other device for applying the brake, sub-
stantially as herein before described.
2. The improved cycle brake hereinbefore described and illustrated in the
accompanying drawings.
