Improvements in the Brakes of Cycles and other Vehicles.
We, JOHN JAMES MENNELL of 4, Standish Street, Burnley, in the County of
Lancaster, Athletic Outfitter, METHUSELAH BROOKS, of Bridge End Whalley, in the
said County, Engineer, and FRANK RICHMOND, of 12 Standish Street, Burnley afore-
said, Engineer and Patent Agent, do hereby declare the nature of this invention to
be as follows:-
This invention has reference to the brakes of cycles, and other vehicles, and is
particularly designed to prevent the wear and tear of the tyres through frictional
contact, as is now the case with the ordinary fixed or rigid brake.
In carrying our invention into effect we mount so as to be capable of revolving on
two, three or more rollers, an endless band of leather, indiarubber, canvas, or other
strong, flexible and durable material. These rollers are mounted in a suitably formed
brake shoe, and are preferably made to revolve loosely on bolts or studs passed through
them, and secured by nuts to the brake shoe, or the rollers may be formed with pins
or pivots, and revolve in centres bored in the brake shoe or otherwise.
The plunger rod of the brake may be of the usual construction, and the brake shoe
may be fixed direct to it, or it may he formed with an extension with hinge
extremities by which it is secured to the fork crown of the machine. The plunger,
in this instance, may be also jointed to the shoe.
The invention may be modified in the form of a foot brake. A clip round the frame
head of the machine firmly holds in position a small plunger rod formed with a knob
end which limits its movement at the top, and is so acted upon by a spiral spring as
to raise the brake shoe, and endless band out of position. The brake is applied by
foot pressure on two arms, which extend from the short plunger rod, and which may
also serve as foot rests.

We, JOHN, JAMES MENNELL of 4, Standish Street Burnley, in the County of
Lancaster, Athletic Outfitter, METHUSELAH BROOKS, of Bridge End, Whalley, in the
said County, Engineer, and FRANK RICHMOND, of 12 Standish Street, Burnley afore-
said, Engineer and Patent Agent, 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 has reference to the brakes of cycles and other vehicles and is
particularly designed to prevent the wear and tear of the tyres through frictional
contact, as is now the case with the ordinary fixed or rigid brake.
In carrying our invention into effect, we mount so as to be capable of revolving on
two three or more rollers, an endless band of leather, indiarubber, canvas, or other
strong, flexible and durable material. These rollers are mounted in a, suitably formed
brake shoe, and are preferably made to revolve loosely on bolts or studs passed through
them, and secured by nuts to the brake shoe, or the rollers may be formed with pins
or pivots and revolve in centres bored in the brake shoe or otherwise.
The plunger rod of the brake may be of the usual construction, and the brake shoe
may be fixed direct to it, or it may be formed with an extension with hinge
extremities by which it is secured. to the fork crown of the machine. The plunger
in this instance may be also jointed to the shoe.
The invention may be modified in the form of a foot brake. A clip round the frame
head of the machine firmly holds in position a small plunger rod formed with a knob
end which limits its movement at the top, and is so acted upon by a spiral spring as
to raise the brake shoe, and endless band out of position. The brake is applied by
foot pressure on two arms, which extend from the short plunger rod, and which may
also serve as foot rests.
In the accompanying drawings, Fig. 1 is a detached view of a brake shoe constructed
in accordance with our invention. A is the brake shoe, which may be lightly
constructed of steel, aluminium, or other suitable metal. It is formed with side
flanges to receive bolts or pins B, C and D. On these pins or bolts are mounted
rollers of metal, or hard wood or other substance E, F and G, and around these rollers
is carried an endless band H of rubber, leather or other frictional material. If made
of rubber, it may be moulded with or have embedded in it an inner lining of canvas
so as to strengthen it, and prevent it from stretching.
The plunger rod J fits by a screw thread into the socket K, and the pin L retains.
them in position. When the plunger rod J is depressed in the usual manner, it
forces the endless band H on the tyre. The endless band H by this means revolves,
and whilst offering considerable frictional resistance to the movement of the bicycle
wheel has not the slightest tendancy to injure the tyre.
The centre roller F may be slightly higher than its two neighbours, so that the
endless band H becomes slightly depressed by the tyre before motion is transmitted
to said roller F.
The screw bolts B, C and D are formed with square shoulders near their heads,
which enter square holes in the brake shoe. They extend to the flange on the opposite
side of the brake shoe, and are securely held by nuts formed with grooves so as to be
fastened by either a screw driver or a wrench. The bolt G is provided with adjusting
slot P so as to tighten the rubber band H, if desired.
Fig. 2 shews a modification of our invention consisting of a hinged extension M,
which may be secured to the back portion of the fork crown. At the top of the brake
shoe are lugs O, which are attached by a pin or bolt to the brake plunger.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The improved arrangement and construction of brake shoe, having an endless
band of leather, rubber or other material H, mounted to revolve on two or more
rollers E, (F), G when in contact with the tyre, substantially as described and
illustrated in Figs. 1 and 2.
