Improvements in Brake Levers for use on Cycles and similar Road
Vehicles,
I, CHRISTOPER HARCOURT SHACKLOCK, of The Ashes, Wolverhampton, in the
County of Stafford, Cycle Works Manager, do hereby declare the nature of this
invention to be as follows:-
The invention has for its object the production of an upward motion, when
a rim brake or other brake demanding a direct upward pull is to be fitted.
In carrying out this invention I take an ordinary brake lever, which I cut
in two pieces at the part generally used to provide the fulcrum, the two cut ends
are then shaped to any suitable design-preferably angled-as shown at C Fig. 1
of the accompanying drawings, other shapes are equally applicable, of which
two are shown in Figs. 3 and 4.
To carry this lever I construct a clip, similar to the one ordinarily used but
made wider to allow room for two pins, upon one of which each piece of the lever
is hinged, thus providing two fulcrums. Upon raising the longer or outer part
of the lever A Fig. 1, the shaped end presses upon its fellow B Fig. 1, and
causes it to take the upward motion desired, on being released, a spring carries
lever back to its normal position.
In the form shown at Fig. 3, the lever is cut through at right angles, a hole
is then drilled through the cut portion, and a roller of suitable size is inserted.
The downward motion exerted on this roller by raising the outer portion of the
lever, causes a corresponding motion in the other part.

I, CHRISTOPHER HARCOURT SHACKLOCK, of The Ashes, Wolverhampton, in the
County of Stafford, Cycle Works Manager, do hereby declare the nature of this
[Price 8d.]

page_text: invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
_
This invention has for its object the production of the upward motion required
where a rim brake or other brake demanding a direct upward pull is to be
fitted.
In carrying out this invention I take an ordinary brake lever which I cut
into two pieces at the part generally made use of to provide the fulcrum. The
two cut ends I shape to any suitable design preferably angled as shewn at C
Fig. 1 of the drawings left with the Provisional Specification, other shapes are
equally applicable of which two are shewn in Figures 3 and 4.
To carry this lever I construct a clip (as ordinarily used to attach lever to
cycle handle bar) wide enough to allow room for two pins upon one of which
each piece of the lever is hinged, thus making two fulcrums. Upon raising the
longer or outer part of the lever A. Fig. 1. the shaped end presses upon its fellow B
Fig. 1 and causes it to take the upward motion desired-on being released a
spring carries the lever back to its normal position.
In the form shewn at Fig. 3 the lever cut through at right angles, a hole
is then drilled through the cut portion, and a roller of suitable size is inserted.
The downward pressure exerted on this roller by-raising the outer portion of
the lever causes a-corresponding upward motion of the other part.
In the-drawings-left with the Provisional Specification:-
--
Fig. 1, is a side elevation shewing lever clipped to handle bar. A is the outer
-or-longer-part of lever, B is the short part which carries the brake mechanism,
C&C, the two shaped ends of lever, D & D the two pins upon-which-tlie-lever-
hinges, E is the clip which holds the lever in place, G is the spring which carries
lever back to its normal position, when not in use Fig. 2 is a side elevation
shewing lever in action.
Fig. 3 is a modification carrying roller F.
Fig. 4 shows another modification in the shape of the ends of the lever.
Like letters denote like parts in each drawing.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:
1. The formation of a compound brake lever to resemble a single lever, for
use on cycles and similar road vehicles, by means of double fulcrum provided in
a single clip, substantially as hereinbefore described.
2. The formation of a divided lever to provide the upward motion required
by a rim brake, by an upward pressure on the free end of lever substantially as
herein before described.
3. The formation of a single clip to provide the double fulcrum necessary to
give the upward action required, substantially as herein before described.
4. The modification in the shape of the fulcrum ends of lever as shewn in the
drawings left with Provisional Specification Figs. 3 and 4 and as hereinbefore
described.
