Improvements in Brakes suitable for Cycles, Motor Cars, and other
Vehicles.
EDWARD REILLY, of 19, Relf Road, East Dulwich, in the County of Surrey,
Printer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is the construction of brake suitable to be applied
to the hub or boss of a wheel say a cycle wheel and is constructed and applied
in the following manner;
On the face of the smaller chain wheel and therefore on the rear wheel of the
cycle I form a circular rim the edge of which forms one surface of the brake.
On the axis of this wheel I apply a disc having a similar rim formed on it.
This disc is capable of being sliden along the axis and so bringing the two rims
into contact. This I do by a suitably formed cam which turns on the axis of
the wheel and is actuated by means of a lever or other suitable appliance. The
surfaces of both rims I form angular so that when pressed together they may
tend to draw more closely into contact and they may also be clothed if desired
with leather or other suitable material.
By these means a very efficient and powerful brake is formed which may be
applied to the hub of the wheel of any vehicle.
Dated this Twentieth day of April 1898.
COMPLETE SPECIFICATION.
Improvements in Brakes suitable for Cycles, Motor Cars, and other
Vehicles.
I, EDWARD REILLY, of 19, Relf Road, East Dulwich, 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:—
The object of this invention is the construction of a brake suitable to be
applied to the hub or boss of a wheel of any vehicle say a cycle wheel.
The drawings hereunto annexed shew its construction and the manner in which
I prefer to apply it.
Figure 1 is a section of the brake shewing also the hub and small chain wheel
of a bicycle. Figure 2 is a face view of the fixed disc shewing the leather ring.
Figure 3 is a face view of the moveable disc, Figure 4 is a back view of the
same. Figures 5 and 6 are views at right angles to each other of the lever for

page_text: actuating the brake. Figures 7 and 8 are views of the sleeve on which parts of
the brake are mounted.
In Figure 1 I have shewn the brake as applied to the opposite end of the axis
on which the small chain wheel is carried and this is the position in which I
now prefer to apply it although it might be applied to the same end of the axis
and will act equally well.
In these figures a is the rear spindle of a bicycle on which is mounted the hub b
and small chain wheel c as usual.
Firmly secured to the hub is the disc d formed as shewn and having an inclined
surface clothed with leather d¹. e is a sleeve carried by the spindle and formed
at its inner end with two projections el e¹ these when the sleeve is in place fit
into the fork of the frame carrying the back wheel and this prevents the sleeve
turning on the axle, the sleeve is also formed with a flat face e² on each side.
The sleeve. when in place on the spindle carries the moveable part f of the
brake formed as shewn and having on it the boss f¹ the face of which is formed
with inclined cam surfaces and also with flat faces f f on the interior of the
boss similar to those on the sleeve e. g is the lever by which the brake is
nctuated it is carried by the sleeve e and is formed with a boss g¹ the face of
which has similar cam surfaces to those on the boss of the moveable part f.
h is a spring tending to hold the fixed and moveable parts of the brake apart.
A cord or rod is attached to the lever g and is led to any suitable part of the
machine say to the handle bar. i is a nut and washer holding the parts firmly
in place.
The continuation a¹ of the spindle a serves as a step as usual.
The action is as follows:-Upon pulling on the cord the cam surfaces on the
boss of the lever g act on the cam surfaces on the moveable part f causing them
to separate, the inclined part f3 is then pressed firmly against the leather ring d
and this acts as a brake to the rear wheel by reason of the moveable part f
being unable to revolve therewith.
The lever g
is able to turn about the sleeve but the sleeve e is unable to turn
about the spindle by reason of the projections e¹ entering the fork of the frame
carrying the rear wheel and the moveable part of the brake is also unable to
turn by reason of the flat faces e on the sleeve with which the flat faces fa fa
on the interior of the boss f¹ engage. f f are gaps in the rim of the moveable
part for parts of the frame of an ordinary bicycle to pass through.
Although I have shewn this brake as applied to the hub of the wheel of a
bicycle it is equally applicable to the wheels of other vehicles such for example
as motor cars.
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:
The construction of brakes for use on wheeled vehicles substantially as shewn
and described.
