Improvements in Brakes for Velocipedes and other Vehicles.
WILLIAM MONK WHITE, 2, Marnock Road, Crofton Park, London, S.E., Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention consists of the ordinary plunger rod the bottom of which has a
forked piece let in, which can be connected by a crossbar for strength, & a pair of
pear or egg shaped arms or rods which are hung on a stud passing through the
fork crown, at the bottom of which shoes are fitted into which rubber, felt, leather
or other suitable material can be fitted to come into contact with the rim or tyre.
The aforesaid arms are worked by studs fixed at the ends of the aforesaid forked
pieces & passing through slots cut in the aforesaid arms causing them to close in
upon the rim or tyre & so stopping the rotary action of the wheel.
Dated this 24th day of June 1898.

I, WILLIAM MONK WILTE, of 2, Marnock Road, Crofton Park, London, in the
County of Middlesex, Engineer, do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement;-
This invention relates to improvements in brakes for velocipedes and other
vehicles and has for its object to construct a simple and effective brake which may
operate either on the tyre or on the rim of a wheel.
According to this invention a brake operating rod forked at one end is arranged
to slide vertically in a manner similar to the rods usually employed for this pur-
pose. The upper end of this forked rod is in some well known manner adjustably
connected to the brake operating hand lever, the arms of the fork being connected
to two brake-levers pivotted at their ends on a stud carried by the crown-piece.
By the endwise movement of the brake operating rod, the brake-levers can be
caused to close upon and grip the tyre or rim of the wheel, the ends of the brake-
levers being provided with pads or blocks of suitable braking material, such as
leather, felt or the like.
In the accompanying drawings Figure 1 is a perspective view of the improved
brake detached from a machine.

page_text: Figure 2 is a front elevation of the brake shown in position on a bicycle, the
parts of the machine being shown in dotted lines.
Like letters indicate like parts throughout the drawings.
The brake operating rod A is forked as at A', the ends of the arms of the fork
being provided with studs A which pass through slots B₁ formed in two brake-
fevers B. The latter are pivotted at one end on a stud C which is carried on a
bracket D provided with a clip or clamp D₁ for attaching it to the head tube or
crown-piece of a cycle. The ends of the studs A are screw-threaded and carry
nuts which retain the studs in the slots B. The levers B carry at their free ends
pads or blocks E of leather, felt or other suitable material. These pads are prefer-
ably arranged so that they can be readily slid in or out of the shoes 13 to allow
of renewal when necessary.
On the outer end of the stud C is mounted a bracket which serves as a guide
for the brake operating rod A and as an abutment against which lies one end of
the spring G for raising the brake out of operation.
The brake operating rod A is provided at its upper end with a clamp or clip H
for connecting it to the rod J which is carried by the end of the brake hand lever
in the usual way.
The clamp D is preferably placed around the portion of the head tube which
lies between the crown-plates or where the construction of the crown will not
admit of this, it may be attached above the crown. The portion of this clamp
which lies towards the rear may conveniently be provided with a tongue D³ for
the attachment of the mud-gear.
As will be seen the whole brake may be readily attached or detached without
affecting other parts of the machine.
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 brake the combination with a forked operating rod A A¹ of brake-
levers B B B pivotted on a pin common to both and so connected to the fork of
the operating rod that movement of the latter closes them and grips the rim or
tyre of the wheel substantially as described.
2. The complete brake substantially as described and illustrated in the accom-
panying drawings.
