Improvements relating to Cycle Brakes.

page_text: Improvements relating to Cycle Brakes.
I, JOSEF ECKART, of Traunstein, in the Empire of Germany, Engineer, do
hereby declare the nature of this invention to be as follows:-
The present invention relates to cycle brakes whose rods are arranged inside
the steering head and concerns the special construction of the devices for setting
and releasing of the brake.
The tubularly extensible brake rod passes along the axis of the steering post
and is guided by a collar therein and the fork crown. It is pushed upwards
by a helical spring consequently the brake block is always lifted.
The upper part of the brake rod is formed of a tube in which a ratchet dog is
arranged, turning on a pivot and pressed outwards by a spring so that its teeth
project from a lateral slot in the tube above an oblique part of the collar
aforesaid.
The top of the brake rod is pivoted to a sliding and rocking block provided
on its outside with a handle, on its inside of a tappet acting against the dog.
When the brake is to be brought into action it is pushed downwards by the
handle.
The dog slides hereby through the collar and is prevented from rising again by
one of its teeth engaging under the collar.
In order to put on the brake very strongly when pushed down as far as possible
can be turned laterally so that it is caught under a pin. It can then be
turned further like a lever by means of which the desired pressure can be got
without difficulty.
To release the brake one pushes the handle straight hereby the tappet releases
the dog free and the spring returns the brake rod.

Improvements relating to Cycle Brakes.
I, JOSEF ECKART, of Traunstein, in the Empire of Germany, 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
statementi:-
The present invention relates to cycle brakes whose rods are arranged inside

page_text: the steering head and concerns the special construction of the devices for setting
and releasing the brake.
The annexed drawing illustrates this invention, Fig. 1 being a longitudinal
section of the steering head, with the afore said device. Fig. 2 a similar view of
part of the same with brake in action and Fig. 3 an exterior view of the steering
bar or part of the same with the handle operating the brake.
The tubularly extensible brake rod a 6 passes along the axis of the steering post
and is guided by a collar d therein and the fork crown e. It is pushed upwards by
a helical spring f consequently the brake block g is always lifted when the brake
is out of action. The upper part a of the brake rod is formed of a tube in which
a ratchet pawl h is arranged, turning on a pivot and pressed outwards by a
spring so that its teeth project from a lateral slot in the tube a in line with an
oblique part of the collar aforesaid.
The top of the brake rod is pivoted at n to a sliding and rocking block m
provided on its outside with a handle o, on its inside with a tappet p acting against
the pawl h.
When the brake is to be brought into action it is pushed downwards by the
handle o. The pawl h slides downwards through the collar d and is prevented
from rising again by one of its teeth engaging under the collar.
In order to put on the break very strongly when pushed down as far as possible
by direct push its handle o can be turned laterally so that its shorter arm abuts
under a pin (Fig. 3). Its longer arm can then be turned further like a lever
acting against the pin r as a fulcrum by means of which the desired pressure can
be got without difficulty.
To release the brake the handle is pushed straight or in other words slightly
lifted, the tappet then withdraws the pawl and the spring returns the brake rod.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that what
I claim is:-
1. A cycle brake, the rod of which is mounted within the steering head, said rod
having a pawl adapted to engage under an abutment to hold the brake in
operative position and having an exterior handle extending from a slot in the
handle bar or otherwise adapted to be pressed down to bring the brake into
operative position and when raised adapted to rotate so as to withdraw the pawl
and suffer the brake to rise.
2. In the brake described in Claim 1 the construction of the handle so that it
may also be rotated in another plane so that one of its arms may be brought
under a lateral abutment and the other arm then serves as a lever for bringing the
brake more forcibly into action.
3. The construction of the cycle brake with setting and releasing devices as ‹
herein described and illustrated in the annexed drawings.
