We CHARLES MONTAGUE LINLEY, Cycle Manufacturer, and THE WHIPPET CYCLE
SYNDICATE LIMITED, both of 57 High Street, Clapham, in the County of Surrey,
do hereby declare the nature of this invention to be as follows:-
This invention relates to cycle brakes, the object being to fix the brake in its
operative position so that it may act as a cycle lock to prevent the machine from
being surreptitiously removed.
In carrying out the invention which may be applied to brakes of various
descriptions such as a plunger, band etc, we prefer to screw-thread the plunger
or equivalent rod and upon this to place a wing nut or the like so arranged that
it can be screwed against the lamp bracket or an equivalent fixed portion of the
machine thus obtaining a purchase by which the brake would be applied and by
screwing the nut sufficiently tight it would be firmly held upon the wheel. The
nut may e arranged to operate with either pull or push rods and may if desired
be prevented from turning by placing a padlock through it. One or more nuts
or equivalent stops may be used to limit the movement of the nut.
Instead of a nut a cam or equivalent device may be used and euer this or the
nut may be arranged so as to be used not merely for locking the brake hard on,
but for holding it with any required pressure upon the wheel so as to relieve the
hand of the rider when descending long hills. In the case of a cam this may be
effected by providing the cam with a handle or extension adapted to engage with
a spring or spring-controlled rack so as to hold it in the required position or the
handle of the cam may be the spring.

Improvements in or relating to Cycle Brakes.
We, CHARLES MONTAGUE LINLEY, Cycle Manufacturer, and THE WHIPPET CYCLE
SYNDICATE LIMITED both of 57 High Street, Clapham, in the County of Surrey,
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:-
This invention relates to an improved brake for cycles and consists of so con-
structing the same as to enable it to be fixed in its operative position so as to act

page_text: as a cycle lock to prevent the machine from being ridden, by any other than the
owner.
The invention is applicable to various descriptions of brakes and comprises means
such as a nut or its equivalent by which the plunger rod of the brake can be forced
up or down so as to press or pull the brake into operation. The plunger is
screw-threaded to receive the said 'nut which latter is arranged to bear upon the
lamp bracket or other fixed part of the machine
In the case of a "push-down" rod for operating the brake as in the ordinary
form of brake bearing in the tyre the nut would be arranged to bear on the under-
side of say the lamp bracket while with a "pull up" type of brake rod such as is
used with a band brake or with a brake acting upon the rim of the wheel the nut
would be arranged to bear on the upper surface of the bracket so that on screwing
the said nut down the brake rod would be raised and the brake applied.
In either case the nut or the brake rod or gear can be provided with an opening
or openings which will correspond with an opening in the lamp bracket or other
fixed, part of the machine when the brake is screwed up or down as the case may
be, so that a pad-lock or other similar device may be applied to lock the brake
in its operative position, and so effectually secure the machine.
Instead of a nut and screw a cam or its equivalent may be employed the cam
being provided with a lover or extension by which it can be partially rotated so as
to apply the brake.
A spring rack can be arranged to hold the lever when so moved and it can be
arranged to not only secure the brake in its "hard on " position but in other inter-
mediate positions so as to partially apply the brake and relieve the hand of the
rider when the cycle is descending a hill.
In the accompanying drawings,
Fig. 1 represents in side elevation sufficient of a head tube and "push down"
brake gear to illustrate this invention which is shown applied thereto
Fig. 2 is a section on the lines 2-2 of Fig. 1,
Fig. 3 is a view similar to Fig. 1 but with the invention adapted to a "pull up
brake and
Fig. 4 is a side view showing a cam arrangement by which the brake can be
operated.
Like letters indicate like parts throughout the drawings.
Referring to Figs. 1 and 2 the brake rod A is provided with a screwed part A',
and passes up through a clearance or opening in the lamp bracket B in the usual
manner so as to be able normally to move endwise there through with freedom. A
nut C which may be provided with a milled edge or otherwise arranged to be readily
turned is screwed on to the part A' and bears against the under side of the lamp
bracket B. The nut C will not interfere with the ordinary action of the brake
but when it is screwed up along the rod A the latter will be forced down and the
brake applied. The nut C can be fixed with a lock nut C or it can be provided
with an opening C (see Fig. 2) through which the arm of a pad-lock D is placed.
When the nut is screwed up the arm of the pad-lock also passes through an
opening B in the lamp bracket by which the brake will be secured in its
"hard-on" position and the machine rendered incapable of being ridden.
Fig. 3 shows the invention applied to a "pull-up" brake its operation being
similar to that already described with the difference that the brake rod A is
raised to apply the brake so that the nut C bears on the upper surface of the
lamp bracket.
In Fig. 4 a cam C3 takes the place of the nut the cam being secured to a shaft
or stud mounted in a bearing B³ secured to the lamp bracket B.
The cam C3 bears on a collar A2 on the brake rod A so that when the cam is
partially rotated the rod is depressed and the brake applied to the tyre with more
or less pressure.
A rack E is secured to the head tube or other suitable part of the machine and
is made sufficiently springy to enable the operating lever C which is secured to

page_text: and operates the cam C3 to pass the teeth at the upper end of the rack and yet be
retained thereby in any desired position to which it may be adjusted to keep the
brake band on.
Two or more teeth are provided to enable the movement of the brake to be varied
as may be desired.
Instead of the rack being springy the lever itself may consist of a spring arm
which will engage with the teeth cf the rack. It will be understood that the
rack E is placed at sufficient distance from the frame of the cycle to avoid fouling
the same in steering and the cam being attached to the lamp bracket will permit
the brake rod to be independently actuated when desired by the ordinary brake
lever. A pad-lock in this case as in the foregoing may be employed to lock the
brake in its "hard-on" position the arm of the said pad-lock either passing through
the lever and rack or through the cam when in its extreme position.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is:-
1. In a cycle the combination with a brake-plunger such as a screw or cam
adjusting device therefor of a pad-lock or its equivalent for the purpose described.
2. In a cycle the combination with the steering head and a brake-plunger such
as A of a screw adjusting-device for the latter substantially as and for the purpose
described and illustrated in Figure 1 or Figure 3 of the accompanying drawings.
3. In a cycle the combination with the steering-head and a brake plunger such
as A of a cam adjusting-device for the latter substantially as and for the purpose
described.
