PROVISIONAL SPECIFICATION.
Improvements in and relating to Brakes for Velocipedes.
I ADOLPHE CLÉMENT of 20 Rue Brunel, Paris, Cycle Manufacturer, do hereby
declare the nature of this invention to be as follows:-
-
My invention relates to an improved brake for the wheels of cycles, and it
consists of a pair of square or other polysided blocks mounted in a frame in such a
manner that when they are brought into contact with the tyre of the wheel the tyre
is not forced bodily down into the rim but is rather squeezed laterally, thereby
avoiding the possibility of cutting the tyre on the edges of the rim. My improved
brake may be applied to either, or both, or all the wheels of a cycle, and it may be
operated by a hand lever or by any other suitable device.
The brake rod is carried in one or more suitable guides so that it has a direct
action on the wheel. On the end of the rod is formed or fixed a double forked
frame, the lateral forks forming a longitudinal fork. In each of the lateral forks is
mounted a brake block, which is preferably square but may be of any other polysided
form. These blocks are mounted on axial pins so that they are free to rotate in
the lateral forks and so adapt themselves to the shape of the tyre, on which
they bear on the sides, the two adjacent faces of the blocks forming a V shaped
recess.
In the accompanying drawing
Figure 1 is a view in front elevation of my improved brake showing its action
on a "solid" tyre.
Figure 2 is a view in side elevation of the brake, and
Figures 3 and 4 are views in front elevation of my improved brake showing its
action on a "cushion" and "pneumatic" tyre respectively.
Throughout these views similar parts are marked with like letters of reference.
A designates the brake rod. B designates the double forked frame. CC designate
the brake blocks which are shown of a square section. b, b, desiguate the bolts
or pins on which the brake blocks are mounted, and X designates the tyre of the
wheel.

COMPLETE SPECIFICATION.
Improvements in and relating to Brakes for Velocipedes.
I ADOLPHE CLEMENT of 20 Rue Brunel, Paris, Cycle Manufacturer, 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 an improved brake for the wheels of cycles, and it
consists of a pair of square or other polysided blocks mounted in a frame in such
a manner that when they are brought into contact with the tyre of the wheel the
tyre is not forced bodily down into the rim but is rather squeezed laterally, thereby
avoiding the possibility of cutting the tyre on the edges of the rim. My improved
brake may be applied to either, both, or all of the wheels of a cycle and it may be
operated by a hand lever or by any other suitable device.
The brake rod is carried in one or more suitable guides so that it has a direct
го

page_text: action on the wheel. On the end of this rod is formed or fixed a double forked
frame in which are mounted a pair of blocks which are preferably square but may
be of any other polysided form. These blocks are mounted on axial pins so that
they are free to rotate or rock in the double forked frame and so adapt themselves
to the shape of the tyre, on which they bear at the sides, the two adjacent faces
of the blocks forming a V-shaped brake block capable of adapting itself to the
shape of the tyre.
Referring to the drawing filed with the Provisional Specification,
Figure 1 is a view in front elevation of my improved brake showing its action
on a solid tyre.
Figure 2 is a view in side elevation of the brake, and
Figures 3 and 4 are views in front elevation of my improved brake showing its
action on a cushion and pneumatic tyre respectively.
Throughout these views similar parts are marked with like letters of reference.
A designates the brake rod. B designates the double forked frame. C, C, designate
the brake blocks which are shown of a square section. b, b, designate the bolts
or pins carried by the frame B and on which the brake blocks are mounted so as
to rock or rotate freely thereon. ✗ designates the tyre of the wheel.
It will be understood that the blocks C may be of any other polysided form and
that they may be of any desired length. The frame B may also be of any other
convenient or desired shape than that shown, so long as it is adapted to carry the
two blocks in such a manner that they will act or operate in the manner illustrated
by the accompanying drawing.
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. The improved construction of brake for velocipedes, as set forth.
2. A brake for velocipedes consisting of two polysided blocks mounted loosely
on pins or axles carried by a frame adapted to be brought into contact with the
periphery of a wheel, as hereinbefore described and illustrated by the accompanying
drawing.
3. A brake for velocipedes consisting of two square or other polysided blocks
mounted in a frame in such a manner, with respect to the wheel-with the periphery
of which the brake is adapted to engage--that the said blocks can accommodate
themselves to the size and shape of the tyre, as set forth.
Dated this 13th day of December 1892.
