page_text: I, FREDERICK JAMES BARNES, of 214, Queens Road, Battersea, in the County
of Surrey, Inventor, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in brakes for cycles and other vehicle
wheels.
In carrying my invention into practice, I construct a disc or friction wheel
with a centre hole to fit over the axle (screwed or otherwise) and a V shaped
periphery; this said disc or friction wheel is drilled with clearing holes for
the purpose of being bolted to the hub of a wheel. The brake is formed by
means of two semicircular ✓ shaped grooved jaws pivoted or loosely bolted
together at its extreme ends, for the purpose of griping the disc or friction
wheel by the operation of a brake handle. The brake handle is connected in
the usual way, by rods and joints, to the open ends of the two V shaped grooved
jaws by means of links or rods loosely pivoted together, in order to close or draw
together the open ends of the two jaws when applying the brake on the friction
wheel.
A suitable curved plate is attached to the fulcrum pin by means of a bolt
and nut, with the other end having a hole passing clear over the end of the
axle.

I, FREDERICK JAMES BARNES, of 214, Queens Road, Battersea, in the County
of Surrey, Inventor, 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:―
My invention relates to improvements in brakes for cycles and other vehicle
wheels.
And in order that my invention may be thoroughly understood, I now proceed
to describe the accompanying drawing thereof, reference being had to letters
and figures marked thereon.
Fig. 1, is a side elevation of the brake.
Fig. 2. is a front elevation of a part of the annaratus.

page_text: Fig. 3, is a front elevation of the disc or friction wheel.
Fig. 4, is the inside of one of the semicircular ✓ shaped jaws.
In carrying my invention into practice, I construct a disc or friction wheel a
with a centre hole 6 to fit over the axle (screwed or otherwise) and a V shaped
periphery a¹; this said disc or friction wheel a is drilled with clearing holes c
for the purpose of being bolted to the hub of a wheel. The brake is formed by
means of two semicircular V shaped grooved jaws a pivoted or loosely bolted
together at its extreme ends e, for the purpose of griping the disc or friction
wheel a by the operation of a brake handle. The brake handle is connected
in the usual way, by rods f and joints, to the open ends of the two V shaped
grooved jaws by means of links g or rods loosely pivoted together on a fulcrum
pin h which works in a slot i cut in the vertical curved plate j, in order to close
or draw together the open ends of the two jaws when applying the brake on
the friction wheel a.
A suitable curved plate ; is attached to the fulcrum pin h by means of a bolt
and nut, with the other end having a hole 7 passing clear over the end of the
axle.
The jaws dare grooved in the inside and in these grooves I insert a packing m
of wood or of any other suitable material. In the top of each of the jaws
I drill three holes n for the purpose of connecting the links g by bolts and nuts o
for adjusting the jaws d as the packing wears against the friction wheel. Each
link g is pivoted between the jaws 2 of the head r to which the rod f is screwed.
A loop e¹ to receive one of the forks is fixed to the vertical plate j by a bolt o¹.
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:-
The brake for cycles and other vehicle wheels constructed and arranged accord-
ing to the above full described specification and according to the accompanying
drawing.
