PROVISIONAL SPECIFICATION.
Improvements in Braking Mechanism for the Wheels of Cycles
and other Vehicles.
We, ARTHUR LINDLEY, of 2, Royal Exchange Buildings, in the City of London,
Average Adjuster, and HEDLEY OLIVER, of St. Benet's Chambers, Fenchurch
Street, in the City of London, Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to brakes for cycles and other vehicles. and has for its
object the arrangement and construction of such a device in the combined form
of a band and shoe brake to act in a simple and effective compensating manner
whereby great retarding effort can be applied to the wheel upon which it acts
without any distorting influence upon the structure of the wheel and spokes as
a whole.
To carry our invention into effect we arrange upon the hub or other part of
the wheel a drum, with which a brake band of the ordinary form is adapted to
operate, one end of the band being attached fixedly to the machine while the
other is connected to the operating mechanism. We also arrange a pivotted arm
on the framework preferably on each side of the wheel so that a brake shoe carried
thereby can be made to press upon the periphery of the wheel, preferably upon
the rim or felloe rather than on the tyre in the case of pneumatic tyred wheels.
A tension device such as a flexible wire is led down from the operating
mechanism which is situated in a position convenient to the rider to the said brake
band and round a pulley carried thereby up again to the pivotted arm to which
it is attached in such a way that upon a tensional strain being set up in the wire
by the operating mechanism, the band will be pulled into contact with the brake
drum and at the same time the pivotted arm will be moved so as to bring the
brake shoe thereon into contact with the periphery of the wheel.
In this way we obtain a combined compensating retarding effort of the brake
band upon the drum carried by the wheel, and of the brake shoe or shoes upon
the periphery of the wheel by the single operation of a single tension cord or
wire.
Suitable riding pulleys or idlers are arranged on the frame of the cycle or
vehicle for altering the direction of lead of the tension cord or wire according to
circumstances or relative arrangement of the wheels with the frame of the
vehicle and the position of the operating device.
We may if desired fit a combined drum brake and shoe brake upon each side of
the wheel and the brake mechanism may be operated by a single tension cord
or wire.

We, ARTHUR LINDLEY, of 2, Royal Exchange Buildings, in the City of London,
Average Adjuster, and HEDLEY OLIVER, of St. Benet's Chambers, Fenchurch

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 brakes for cycles, and other vehicles, and has for, its
object the arrangement and construction of such a device in the combined form
of a band and shoe brake to act in a simple and effective compensating manner
whereby great retarding effort can be applied to the wheel upon which it acts
without any distorting influence upon the structure of the wheel and spokes as
a whole.
:
To carry our invention into effect we arrange upon the hub or other part of
the wheel a drum with which a brake band of the ordinary form is adapted to
operate, and to be tightened by the operating mechanism. We also arrange a
pivotted arm on the framework preferably on each side of the wheel so that a brake
shoe carried thereby can be made to press upon the periphery of the wheel, pre-
ferably upon the rim or felloc rather than on the tyre in the case of a pneumatic
tyred wheel.
A tension device such as a flexible wire is led down from the operating
mechanism which is situated in a position convenient to the rider, to the said brake
band and round a pulley carried thereby up again to the pivotted arm to which
it is attached in such a way that upon a tensional strain being set up in the wire
by the operating mechanism, the band will be pulled into contact with the brake
drum and at the same time the pivotted arm will be moved so as to bring the
brake shoe thereon into contact with periphery of the wheel.
In this way we obtain a combined compensating retarding effort of the brake
and upon the drum carried by the wheel, and of the brake shoe or shoes upon
the periphery of the wheel by the single operation of a single tension cord or
wire.
Suitable riding pulleys or idlers are arranged on the frame of the cycle or
vehicle for altering the direction of lead of the tension cord or wire according to
circumstances or relative arrangement of the wheels with the frame of the
vehicle and the position of the operating device.
In order that our invention may be the better understood we will now proceed to
describe it in relation to an ordinary safety bicycle as an example reference being
had to the letters and figures marked thereon. Like letters refer to like parts in
the various figures.
Figure 1, is a side elevation and
Figure 2, a plan of the rear wheel axle and part of the framing as far as the
cranks, showing the attachments being rim levers and axle and bell crank lever.
Figure 3 shows the steering handle with brake lever.
A is a drum cast on or properly secured to the side of the sprocket wheel a;
round the circumference of this drum is carried a steel strap a secured at ends 3
and e to the bell crank lever B; this lever is carried upon a pin C clamped on the
horizontal fork in such a manner that it can be moved towards the centre of the
wheel as required for effecting the driving chain adjustment and having a
spring sufficiently strong to return the lever B into normal position when the

page_text: pull on the brake is released. The upper end of the crank B carries a small
pulley free to revolve on its axis round which a wire c¹ is carried to connect it
with rim brake at X, the other end of the wire c¹ being carried round a pulley Y
on the frame and along the frame under the pulley Z up to the handles.
The rim brake is composed of two levers D and E centred on pins F and F¹
carried on the inside of the forks. The upper end of each of these two levers D
and E carry a brake shoe G shaped at circumference to fit the rim of wheel and
free to pivot upon pins f and f¹. The heads of these pins and the inner surface
of the shoes must be sufficient distance apart to allow the valve on the rim to pass.
A connecting band H is hinged to pins f and f¹ and is connected to a lever J
pivotted on the frame. A spring K is arranged to press against the lever J the
lower end of the spring being attached to the frame at L.
The lever J is carried down to X for the wire attachment, and may be made
adjustable as to its pivot to allow of the adjustment of the wheel for tightening
the chain.
It will be obvious that the action of the brake lever has a combined effort upon
the band and shoes, which results in a braking action being set up in both devices
simultaneously.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is:
1st. A combined braking device for the wheels of cycles or other vehicles con-
sisting of a band braking device, a rim braking device, and means for simul-
taneously operating same in a compensating manner, substantially as described.
2nd. In a combined braking device for the wheels of cycles or other vehicles,
a band brake and a rim brake in combination with a flexible cord wire or the like
adapted to operate round pulleys or the like carried by the levers of the braking
devices, go that the pulling of the cord or wire simultaneously operates the two
braking devices in a compensating manner, substantially as described.
