PROVISIONAL SPECIFICATION.
Improvements in Brakes for Cycles and other Vehicles.
I, GILBERT WHEATON BADDELEY, of 2, Molyneux Place, Morice Town, Devon-
port, Engine Fitter and Erector, do hereby declare the nature of this invention
to be as follows:-
My invention relates to improvements in brakes for cycles and other vehicles,
and the object to provide a brake which can be applied with unfailing certainty
of effect. In carrying my invention into practice, I proceed in or in about the
following manner. Each end of the wheel hub is made with a (preferably) disc
like surface, provided with an outwardly projecting rim or flange. Each end of
the axle has a screw thread of rapid pitch. Screwing on each threaded end of
the axle is the boss of a brake disc, the brake disc fitting closely within the pro-
jecting rim or flange on the end of the hub, but in such manner that when in their
normal position, the opposing surfaces will not be in contact with each other.
The bosses of the brake disc are held by the ends of the arms of the usual fork
of the machine.
To each screwed end of the axle is attached a downwardly pointing crank, to
the pin of which is attached one end of a connecting rod. Each of these con-
necting rods extends from the pin to the opposite ends of a cross bar some little
distance below the handle bar, a rod connecting this cross bar with the brake
lever, one end of which is pivotted to the handle bar, the other end being within
grasp of the rider so as to be readily pressed up for applying the brake.

the brake, the rider presses upwards the free end of the brake lever, this action
raises the rods extending to the cranks on the wheel axle, and causes a partial
rotation of the latter. The action of the screw thread on the female threads on
the inside of the brake disc bosses, causes the brake discs to come in contact with
the hub discs and so brake the wheel. The thread at one end of the axle is of
course right handed, and that at the other end left handed. The axle may be
tubular for a part or the whole of its length to ensure lightness.

Improvements in Brakes for Cycles and other Vehicles.
I, GILBERT WHEATON BADDELEY, of 2, Molyneaux Place, Morice Town, Devon-
port, Engine Fitter and Erector, 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 improvements in brakes for cycles and other vehicles
and the object is to provide a brake which can be applied with unfailing certainty
of effect. In carrying my invention into effect I proceed in or in about the

page_text: following manner making reference to the accompanying sheet of drawings in
which Fig. 1 is a part sectional front view and Fig. 2 a side view of hub only.
Although the drawings and description apply only to the brake in connection
with a cycle, I do not confine it to that one class of vehicle as by suitable modifica-
tion it can be applied to vehicles of other kinds. Each end of the hub a is made
with a (preferably) disc-like surface b, provided with an outwardly projecting
rim or flange c. At the ends of the axle are the screw threads d of rapid pitch,
one right handed and the other left handed. Screwing on the threaded ends of
the axle are the bosses e of the brake discs f, which fit closely but freely within
the rim c. In their normal position b and f are not in contact with each other.
Each disc is provided with a dovetailed ring groove in which are held blocks
of hard wood or other suitable material.g, which when the brake is out of use are
away from b. The bosses e are held by, but free to move longitudinally in, bear-
ings at the ends of the arms of the fork h of the machine and each boss has a
feather to prevent the boss turning round in the bearings at the end of h. To
each screwed end of the axle is attached a downwardly pointing crank ; to the pin
of which is attached one end of a connecting rod k, the connecting rods being
joined by a cross bar / some little distance below the handle-bar m, a rod n con-
necting with the brake lever o one end of which is pivotted to m as at p, the
other end being within grasp of the rider so as to be readily pressed up when the
brake is to be applied and a spring 7 may be provided to keep the free end of o
downwards. To apply the brake the rider presses upwards the free end of
this raises the rods k, which by acting on the cranks ; cause a partial rotation of
the screws d, and d working inside the female threads of the bosses e cause the
discs to come into contact with b and so brake the wheel. The axle may be
tubular for a part or the whole of its length to ensure lightness.
and
I do not confine myself to the precise shapes, relative proportions or dispositions
of parts as shown in the drawings or described in the above specification as any or
all of them may be considerably varied to suit the circumstances of each case or
vehicle to which the invention may be applied and this without departure from the
essential features.
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. Improvements in brakes for cycles and other vehicles, the said improvements
consisting essentially in providing the hub of the wheel with disc like ends and
the ends of the axle of the wheel with right and left handed screw threads on
which threads are screwed the bosses of brake discs which can be brought into con-
tact with the ends of the hub as and when required by more or less rotating the
screwed ends of the axle, which movement of the screwed ends is brought about
by connecting rods acting on cranks attached to the axle ends, the said rods being
connected by a cross bar which can be raised or lowered by a brake lever adjacent
to the handle bar of the vehicle, the bosses of the brake discs being carried and
free to move longitudinally but not rotate, in suitable bearings at the ends of the
fork carrying the axle, the whole substantially as described in the above specifica-
tion and exemplified in the accompanying drawings.
2. Improved vehicle brakes constructed substantially as described in the above
specification and exemplified in the accompanying drawings.
