Brakes for Free Wheel Motor and other Cycles.
WILLIAM GEORGE ARTHUR, 126, Lordship Lane, East Dulwich, London, S.E.,
Engineer, do hereby declare the nature of this invention to be as follows:-
A brake for free wheel motor and other cycles," this invention consists
of an adjustable or fixed attatchment to bottom bracket to which is hinged or
pivoted a lever shaped to receive the heel forward and above crank axle. The
pressure to be applied on one end with the heel of boot without removing the
foot from the pedal the power is then transmitted to the other end of said lever
to this end of lever is hinged a rod, and at other end of rod is hinged a lever
carrying a rubber block at lower end for brake contact and at upper end works
rim brake.

Brakes for Free Wheel Motor and other Cycles.
I, WILLIAM GEORGE ARTHUR, 126, Lordship Lane, East Dulwich, London, S.E.,
Engineer, 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, reference being had to the accompanying
drawings:-
This invention relates to brakes for free wheel motor and other cycles and
consists of an adjustable or fixed attachment to bottom bracket to which is
hinged or pivotted at X a lever a shaped to allow the pressure to be applied on
one end A with the heel of the boot without removing the foot from the pedal;
the power is then transmitted to the other end B of the said lever a. To this
end B of lever a is hinged a rod band at the other end of the rod b is hinged
at C a lever c carrying a rubber block at lower end for tyre contact and at
the upper end works a rim (or band) brake c. A coiled or other spring or
equivalent may be arranged, preferably at X, to throw the brake out of gear
when not in action. The clip or the like by which the brake levers are
pivotally suspended at X or C may be detachably connected or brazed to either
the bottom bracket, back fork or other part of the cycle or motor.
It will be seen that the connecting rod is divided and telescopic and the
brake therefore adjustable by a screw f, nut or equivalent to accommodate
varying distances between the crank axle and back wheel centres, though I
prefer to construct each brake, lever and rods to standard dimensions.
In some cases moreover I simplify the arrangement shewn and described with

page_text: reference to Figure 1 and dispense altogether with the rod b, the iever a being
proportionately lengthened and the cranked end or other arm serving as the
brake lever c, Figure 2.
Furthermore, when applying my invention to a cycle or motor wherein it is
preferred to employ a band or like brake on the hub of the back wheel I may
substitute same in lieu of the rim brake at e whilst still employing the tyre
brake d, or, I may dispense with the latter also, prolong or lengthen the
adjustable connecting rod b. and attach the rear extremity to the band brake
of the back wheel hub which arrangement may be more suitable with free wheel
motors.
I do not confine myself to the precise details of construction described and
shewn as same may be varied as and when required without departing from
the principle or characteristic features of my invention, viz.:-The production
of a brake for free wheel cycles and motors to be operated by the heel of the
rider without removing the foot from the pedal, the levers, rods, cranks, or con-
nections permitting the employment of either a tyre, rim or hub brake according
to circumstances and requirements.
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:
In cycles, motors, or the like the combination with a "free wheel" of a back
wheel brake either tyre, rim, or hub to be operated by the heel of the rider
without removing the foot from the pedal in the manner and by the means
substantially as herein before fully set forth and shewn and for the purposes
specified.
