Improvements in Brakes for Bicycles and the like.
Year: 1897

page_text: We GEORGE HENRY RICHMOND and JOSEPH CROWTHER both of 5 Derby Street
Moss Side Manchester in the county of Lancaster Engineers do hereby declare the
nature of this invention to be as follows :-
In carrying out our invention we mount through the handle bar stem a spindle
terminating at its upper extremity in a screw thread for the purpose of engaging
with an adjusting nut as hereinafter described.
The lower end of this spindle we connect in any suitable manner to the brake
block or blocks such block or blocks being designed to engage against the rim of
the wheel or against a disc or discs mounted upon the wheel. Upon a fulcrum mounted
upon the handle bar we further arrange a lever to engage with the adjusting
nut hereinbefore described and this lever we then divide and continue along the
handle bar and terminate underneath each handle. It will now be seen that upon the
lever being lifted such lever will engage with the adjusting nut and so lift the spindle
and cause the block or blocks to come into contact with the rim of the wheel or with
the disc or discs and by this means a very powerful brake to such wheel is ensured.
Dated this 21st day of January 1897.

Improvements in Brakes for Bicycles and the like.
We GEORGE HENRY RICHMOND and JOSEPH CROWTHER both of 5 Derby Street
Moss Side Manchester in the county of Lancaster Engineers 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 stateinent :-
In carrying out our invention we mount through the handle bar stem a spindle
terminating at the upper extremity in a screw thread for the purpose of engaging
with an adjusting nut as .hereinafter described the lower end of this spindle we
connect in any suitable manner to the brake block or blocks such block or blocks
being designed to engage against the rim of the wheel or upon a disc mounted
upon the wheel or against any moving part desirable. The adjusting nut is
provided with a groove into which groove take two pins, which pins are secured into
a sleeve surrounding the händle bar stem, the nut is further continued upwards and
through the upper surface of the handle bar and is terminated in a suitable knob,
Branching from the sleeve above described are two levers one extending under each
handle or on one side and depending from the handle bar we may arrange a fulcrum

continued and terminating underneath the handle. It will now be seen that upon
the lever or levers being lifted the sleeve will be raised up. the stem, and cause the
pins to raise the nut, and so lift the spindle when the blocks will be brought to bear
upon the rim of the wheel or other moving part to which they may be applied. 5
And in order that our invention may be more rapidly understood and carried into
effect we have hereunto annexed a sheet of drawings which we will now proceed to
describe with the assistance of the Figs and letters marked thereon, like letters being
used in all views to denote like parts.
Figs 1 and 2 are sectional views showing two methods of applying our 1
invention.
Fig 3 is a sectional plan to more clearly illustrate the pins and
Fig 4 is a plan of the brake blocks as applied to the rim of a wheel.
In figs and 2 A is the handle bar from which is depending the stem B through
which stem B is mounted the spindle C terminating at its upper end in a screw
thread D for the purpose of engaging with the adjusting nut E the lower end
of this spindle C we connect in any suitable manner with the brake block or blocks F
such block or blocks being designed to engage against the rim G of the wheel or
upon a disc mounted upon the wheel or against any moving part desirable. The
adjusting nut E is provided with a groove H into which groove H take two pins I 2
which pins I are secured into the sleeve J surrounding the handle bar stem B and
are arranged to pass through the slots K formed in the stem B for the purpose of allowing
movement to the sleeve J and pins I the nut E is further continued upwards and
through the upper surface of the handle bar A and is terminated in a suitable
knob L. Branching from the sleeve J above described are two levers M and N one
extending underneath each handle, Or on one side and depending from the handle
bar we may arrange a fulcrum O to engage with one of the levers M or N branching
from the sleeve the other lever being continued and terminated underneath the handle.
It will now be seen by referance to Fig I that upon the levers M and N being
lifted, the spindle C will be raised and so cause the blocks F to engage against the
rim G or by referance to Fig 2 it will be seen that upon the lever N being raised the
lever M will work upon its fulcrum and the same result will take place. The
adjusting nut E is provided for taking up the wear upon the brake blocks F and als
for the purpose of applying the brake and leaving it on the wheel whilst descending
long declines, and by this means the hands are greatly releived. Although we have
only illustrated our invention as applicable to the rim of the wheel of a bicycle or
the like it will be obvious that it may be applied to any moving part of a bicycle or
the like and instead of blocks, bands or anyother contrivance may be used for
forming frictional contact.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
Firstly. In combination the nut E spindle C pins I sleeve J levers M and N and
or fulcrum O as and for the purposes hereinbefore described and illustrated on the
accompanying drawing.
Secondly. The combination and arrangement of mechanism as and for the
purposes hereinbefore described and illustrated on the accompanying drawing.
