hereby declare the nature of this invention to be as follows:-
A contrivance for regulating by friction the speed of cycles, the essential feature
of which is that it secures the upward pressure of leather pads against the under
side of the rim of a cycle wheel by the downward movement of a rod attached
to the brake itself and to a lever which is attached to the cycle handle-bar. The
said rod and lever are the same as are in use upon the great majority of cycles,
and the invention is attached to the rod just above the rod-clip at the fork crown
by two hinge joints, is carried down the face of the fork-crown about an inch,
where it is hinged again, and carried to the forks one inch below the crown,
and attached thereto by hinged joints, from which it is carried to both sides of the
inner rim of the cycle wheel, where the leather-pads hang about an eighth of an
inch clear of the rim. The pads are brought into contact with the under side
of the rim of the wheel by pressing the handle of the lever attached to the handle-
bar against the said handle-bar. The invention can be applied to the back wheel
or wheels of a cycle by an adaptation of the rod.

Cycle Brake,
JOHN HARRISON, 309, Tong Street, Dudley Hill, Bradford, Cycle Maker, do
hereby declare the nature of this invention and in what manner the same is to be
performed, to be paricularly described and ascertained in and by the following
Statement:-
My invention relates to an improved cycle brake which has for its objects sim-
plicity of attachment and details of construction together with an effective fric-
tional contact with the metal rim of the wheel when put into action.
Its essential features consist in the usual down rod in front of the fork guided
at the bottom end and fitted with lugs projecting on each side of the rod near the
bottom end; a couple of short links attached to the said lugs; a couple of bent
levers articulating with the said links and bent in such a way that their extreme
ends may point against the inner surfaces of the wheel rim on either side of the
spokes, and pivoted on brackets fixed to the limbs of the front fork; rubber or

ends of the bent levers.
In the accompanying drawings Fig. 1 is a side view or elevation of the brake
as it appears fixed in position on the cycle.
Fig. 2 is a front view or elevation of the same and shows the wheel rim and tyre
in section.
Similar letters refer to similar parts in both views.
With reference to these drawings F is the down rod or tube worked by the usual
spoon lever on the handle bar, guided at its lower extremity by the bracket C.
Projecting on each side of the rod F are the lugs J to which are jointed
the links E by means of the pins G. The brackets Bare fixed to the limbs of the
fork in the usual way and are fitted in front with studs or screws I so as to form
centres on which bent levers D are pivoted, the letters D being jointed or articu-
lated at their upper ends with the links E by the pins H. Flat plates of metal A
are fitted or formed on the curved ends of the levers D parallel with the inner
surface of the wheel rim so as to present considerable area for the interposing
medium of rubber or other suitable material K, which is fixed to the faces of
the metal plates A, to act on the wheel rim when pressed thereto by the action
of the brake.
The operation of the brake is as follows:--When the rod F is depressed, the
ends of the short links E, at H, are expanded outwards taking with them the
upper ends of the bent levers D, which being pivoted at I swing their lower ends in
towards the rim at A, the resulting pressure at these points depending on the
amount of depression given to rod F. The parts are returned to their inoperative
positions by a suitable spring as will be well understood.
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. In a cycle brake the combination with the rod F, of links E, coupled thereto,
levers D pivoted on the frame of the cycle and coupled to links E and having at
their lower ends brake surfaces to bear against the rim of the cycle wheel when the
rod F is depressed, substantially as described.
2. The general arrangement, construction and combination of parts forming my
improved cycle brake substantially as described and shown herein with reference
to the accompanying drawings.
