PROVISIONAL SPECIFICATION.
An Improved Stop or Brake for Vehicle Wheels.
I, FREDERIC HUGHES, of 20, Paget Road, West Dulwich, London, Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to an improved stop or brake for vehicle wheels and the
object is to provide a simple, promptly applicable and effective article of the kind
for use on all kinds of wheeled vehicles. In carrying my invention into
effect I proceed in or in about the following manner. I attach to the hub of the
wheel a sprocket-wheel and to the body or frame of the vehicle I pivot a lever,
to one end of which is pivotted a shoe having in it holes (preferably somewhat
slotted), the said holes being so distanced from one another as to fit over some of
the sprockets of the sprocket-wheel. I so arrange that the weight of the shoe
will keep the shoe with its holes encircling some of the sprockets already
mentioned and so prevent the wheel from turning. The shoe can be lifted from
the sprocket-wheel, to release the wheel, by any suitable means operated in any
suitable manner, as by a rod or arrangement of levers operated from the drivers
seat or by the handles employed in moving the vehicle. In the case of a cab the
lever may be so pivotted and the rod so attached thereto that on the driver taking
his seat the shoe will be lifted from the sprocket-wheel and on his leaving his seat
the weight of the shoe will cause it again to descend on to the sprocket-wheel
and so brake the vehicle-wheel. Suitable means may be provided for fixing
the shoe in or out of its active position as and when required.

COMPLETE SPECIFICATION.
An Improved Stop or Brake for Vehicle Wheels.
I, FREDERIC HUGHES, of 20, Paget Road, West Dulwich, London, 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 follow-
ing statement:-
My invention relates to an improved stop or brake for vehicle wheels and the
object is to provide a simple promptly applicable and effective article of the
kind for use on all kinds of wheeled vehicles. In carrying my invention into
effect I proceed in or in about the following manner making reference to the
accompanying drawings of which Fig. 1 is a side view of the brake, Fig. 2 being
a side view of an arrangement for making the application of the brake automatic
I attach to or alongside of the hub a of the wheel b a sprocket wheel c and to the
body or frame of the vehicle I pivot a lever d, to one end of which is pivotted a
shoe e having in it holes or indentations f (somewhat elongated) the said holes
or indentations being so distanced from one another as to fit over some of the
sprockets of the wheel c. I so arrange that the weight of the shoe e will keep
some of its holes or indentations in engagement with the sprockets
and so prevent the wheel from turning. The shoe e can
be lifted from

page_text: the sprocket wheel to release the wheel by any suitable means operated
in any suitable manner as by a rod or arrangement of levers operated from
the driving seat or by the handles employed in moving the vehicles as would
be the case with a perambulator for instance. The application or removal of
the brake might be effected in the case of a cab or other vehicle by the driver
taking or leaving his seat and a simple arrangement of the kind is shown by
Fig.
of the accompanying drawings wherein the hinged seat is kept clevated
by a spring such as in which position the rod is drawn up and causes the
shoe e to be put over the sprocket wheel thus braking the wheel. When the
driver takes his seat his weight overcomes the spring and the hitherto elevated
part is depressed and with it the rod i thus raising the shoe e and so releasing
the wheel. If an automatic motion is not required the rod i may be arranged
to revolve in a socket pivotted at the free end of the shoe lever d. The upper
end of the rod would then be arranged to slide in a split socket in such manner
that when the rod is raised a pin projecting therefrom will pass along the slit
in the socket and so soon as it has passed out of it at the upper end of the socket
the rod can be rotated so as to bring the pin to rest on the top of the socket.
The
end of the rod i may also be "racked" and raised and lowered by the action of a
toothed quadrant gearing in the rack. Again in some cases the brake might
be arranged so as to be applicable by a person standing on the ground instead of
or in addition to, the provision for its application from the driver's seat. With
perambulators and the like the handle might be so pivotted as to apply the brake
by depressing or raising them and such movement may be controlled by a spring.
In all cases when a spring is employed whether for raising the drivers seat or for
any equivalent purpose a suitably placed weight may be substituted and further
the rod is by no means necessary in all cases as direct movement of the end
of the lever d may be employed for putting on the brake.
I do not confine myself to the precise shapes or arrangements of parts shown in
the drawing as variations are possible therein without departure from the essential
features of the invention.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-
:-
1. The method of braking vehicle wheels by the application of a perforated
or indented shoe to the sprockets of a wheel having its axis coincident with that
of the vehicle wheel substantially as described in the above specification and
exemplified by the accompanying drawings.
2. In an improved stop or brake for vehicle wheels the, combination of a
sprocket wheel placed axially coincident with the hub of the vehicle wheel, a
perforated or indented shoe to engage with the said sprocket wheel, a lever to
which is pivotted the said shoe and means whereby the said lever can be auto-
matically or otherwise operated so as to put the said shoe in or out of engagement
with the said sprocket wheel, the whole substantially as described in the above
specification and exemplified by the accompanying drawings.
3. In stops or brakes for vehicle wheels such as are the subject matter of the
above claims 1 and 2 the method of operating the brake automatically the
action of a spring or weighted driver's seat, substantially as described in the above
specification and exemplified by the accompanying drawings.
4. The improvements in stops or brakes for vehicle wheels provided for and
operating substantially as described in the above specification and exemplified
by the accompanying drawings.
