PROVISIONAL SPECIFICATION.
An Improved Brake for Cycles or other Vehicles.
I JOHN BLACK PEGDEN, of Central Cycle Works, Anlaby Road, Hull, in the
County of Yorkshire, do hereby declare the nature of this Invention, to be as
follows:-
The object of my invention is to provide a brake for cycles or other vehicles,
which brake shall be actuated by means of air, liquid, or by lever, and which shall
be quick of action, and also, is not required to be held by the hand all the time
it is on, as is the ordinary lever brake, at the same time nearly the whole brake
arrangement is hidden from view. I construct my invention as follows:-In
any part of the interior of the handle bar or steering tube of the machine,
I employ a piston, or ram, this acts upon the brake, and is actuated by air, or
liquid passing through a tube inside the handle bar, this tube runs along the
inside of the handle bar, from the handle or any other suitable part, and is there
connected to a small pump or bulb, the rider when wishing to apply the brake
simply presses the bulb or the pump on the handle, this admits air or forces the
water to the pump in the stem or steering tube, and forces the brake down,
thus causing it to operate, it is kept in use until relieved by means of a small
release valve, placed in any suitable position, almost the whole of the contrivance
being hidden from view.
In the lever arrangement a straight rod is passed down the inside of the stem
or steering tube, and connected to the brake, this keeps the brake mechanesm
entirely out of sight, the rod being actuated by means of a push let into the top
of the handle bar, or any other suitable means.

I, JOHN BLACK PEGDEN, Engineer, of Central Cycle Works, Analby Road, Hull,
in the County of York, 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 construction of my invention, is carried out as follows and consists of two
metal Cylinders the one hereafter called, the Hand Cylinder Fig. 1 and the other

page_text: hereafter called the Brake Cylinder Fig, 6, the Hand Cylinder Fig. 1 is fixed to
Handle bar of Cycle, and connected to brake cylinder 6, by a metal tube Fig. 4
which is passed inside the Handle bar,, and down through the head or stem of
cycle and near the lower end of said head or stem, the said bube Fig. 4 is con
nected to brake cylinder 6, the apparatus being so arranged that by the pressure
of the hand or closing of the fingers, the air, oil or like substance, is driven by
the piston of the Hand Cylinder down the metal connecting tube Fig. 4 and acts
upon the brake cylinder piston, and forces down the brake Fig. 8 until it comes
in contact with the tire Fig. 9, thereby retarding the progress of cycle or other
vehicle to which it may be attached, the piston rod of the hand cylinder (projects
from that part of the handle bar that is grasped by the hand) in a downward
direction, the end of said piston rod being fitted with finger grips Fig. 3, so
arranged that by the action of closing the hand the brake Fig. 8 is put into
instant use. The brake is released by loosening the grasp and allowing a spiral
spring Fig. 7 that is placed on the under side of brake piston, and between the
piston and the cylinder end, to force the piston upwards and into its normal
position, at the same time replacing the air, oil or like substance used for trans-
mitting power, further the aforesaid metal tube connecting the two cylinders,
so provided with a telescopic joint & gland, so arranged that the handle bar of
cycle may be raised or lowered, without altering the adjustment of the brake,
the hand cylinder is provided at its upper end, with a filling plug or screw Fig. 10
so that the air, oil or like substance employed may be replenished at will, the
upper part of the connecting tube, is made of very small bore, to prevent a too
sudden application of brake, as the air, oil or like substance can only be driven
through the said tube in small volume, thereby graduating the descent of brake.
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. The use of Hand Cylinder Fig. 1 at right angles to the Handle bar of cycle
and the finger grips Fig. 3 thereto attached, the cylinder Fig. 1 being passed
through the section of Handle bar.
2. The fixing of an internal connecting tube Fig. 4 between the two cylinders
of brake, the said tube having a telescopic Joint & Gland so arranged that the
Handle bar may be raised or lowered, or turned round in the socket, without
disturbing the adjustment of brake.
3. The extreme lightness of the device its imperishability it being composed
wholly of metal, excepting piston packings.
4. Simplicity of construction, and directness of action, and particularly the
small bore of connecting tube Fig. 4 to prevent to sudden application of brake,
Fig. 8.
