PROVISIONAL SPECIFICATION.
An Improved Brake for Bicycles, Tricycles, and other Suitable Road
Vehicles.
We, WILLIAM LINNELL, of 30, Spring Street, Spring Bank, Hull, in the County
of Yorkshire, Accountant, and SAMPSON NEWMAN, of Laburnham House, King's
Heath, Birmingham, in the County of Warwickshire, Merchant, do hereby declare
the nature of this invention to be as follows:-
The object of our invention is to provide an improved brake for bicycles,
tricycles and other suitable road vehicles, by means of which there is no strain
on the wheels of the cycle or the like, and greater brake power can be obtained
than with the ordinary construction of brakes at present in use, and and with less
liability to accident.
Our invention consists in applying the brake to the pedal crank axle.
For the purpose of our invention we place the spoon or clip part forming the
brake within the tube of the bottom bracket which forms the bearing for the
pedal crank axle, the brake may be operated by means of an operating lever
articulated to the bottom bracket or other suitable part of the machine frame,
such lever being connected to the brake by means of a pin provided with a spiral
spring or the like, the operating lever being connected to a rod or rods which
may have quadrants or other connecting device to form the brake mechanism,
and may be worked by means of a grip attached to the handle bars of the machine
or by means of foot mechanism on the front pillar or other suitable part, or the
connections may be run to the saddle so that the rider can operate the brake by
leaning back or tilting the saddle; also if desired the brake may be locked when
the machine is left in the street or other place unattended, by means of a barrel
provided with a ratchet wheel and pawl or other arrangement mounted on the
front pillar or the handle bars, or in any other suitable position, a chain band or
the like having one of its ends attached to the brake rod and its other end to
the barrel, is employed, such chain or the like by being wound on to the barrel
pulls up the brake rod and so locks the brake the pawl engaging with the ratchet
wheel preventing it unwinding until released so that the machine may be left
unattended, being securely braked.

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: —

DESCRIPTION OF DRAWINGS.
Fig. 1 represents a side view of a safety bicycle with our improved brake
applied, the tube which takes the crank axle being shown in section.
Fig. 2 is a plan view of Fig. 1.
Fig. 3 represents a side elevation of part of a safety bicycle showing brake
fitted so as to be operated by depressing the saddle.
Fig. 4 represents a side view of part of a bicycle showing one method of
mounting brake so that it can be operated by the feet.
Fig. 5 is a sectional side view of tube for taking crank axle showing a modified
form of fixing brake.
Fig. 6 is an underside view of same, but with tube in full with the exception
of the hole for the ends of the brake to work in.
Fig. 7 is a sectional side view of tube and crank axle showing a brake having
one end a fixture inside the tube and the other end connected to the brake rod.
Fig. 8 represents an underside view of tube with brake in position and
Fig. 9 is an underside view of brake proper showing one end working within
the other.
Figs. 3 to 9, are drawn to a larger scale than the other views.
Our invention consists in applying the brake to the pedal crank axle.
For the purpose of our invention we place the spoon band or clip part forming
the brake A within the tube B of the bottom bracket C which forms the bearing
for the pedal crank axle D such band or clip fitting around the crank axle, which
may be enlarged if desired so as to form a larger surface for the brake to
encircle, an opening B₁ being made in the tube B to receive it, the brake A may
he operated by means of an operating lever E articulated to the bottom bracket C
or other suitable part of the machine frame, such lever being connected to the
brake A in any suitable manner, the operating lever E being connected to a
rod or rods F which may have quadrants, arms or other connecting device G to
form the brake mechanism, and may be worked by means of a grip H attached to
the handle bars J of the machine, a suitable joint H' being provided at the part
where the grip is connected to the arms G or in place of the grip it may be worked
by means of foot mechanism on the front pillar or other suitable part.
In this case the quadrants or arms G may form the foot rests, the rod or
rods F which run to the brake A may be connected to the front of the quadrant
or arms G the back parts of such arms forming projections for the rider to place
his feet upon, so that by depressing them the front parts are tilted up and pull
the brake rod or rods up, so putting the brake on.
The connections may be run to the saddle or seat K so that the rider can

page_text: operate the brake by leaning back or tilting the saddle in the two latter cases no
grip attached to the handle bar is required.
In place of employing a lever attached to the brake, the rod or rods F may be
connected to one end of the band which forms the brake, the other end of such
band bearing against the metal of one side of the hole B¹ in the tube in which
the brake is placed as shown at Figs. 5 and 6 or the band A may be fixed at one
of its ends to a point inside the tube B by means of screws or the like L and the
other end be connected to the brake rod or rods direct or by means of an inter-
mediate lever or pin E; a spring M being connected to the pin or lever E and to
the back stays or other suitable part of the frame for drawing such lever back
into its original position after the brake handle is released.
The band A which forms the brake may have a piece cut out of one end
preferably of the end A' fixed to the inside of the tube the other end A2 being
made to form a piece similar in shape to the opening or recess in the end A¹
formed by the cutting of a piece out of such end, the lever or pin E is attached
preferably to the end A2 and a slit B' is made in the tube in the direction of the
movement of the lever or pin, as the brake rod pulls this pin the brake is tightened
around the crank axle and grips it tightly the end A2 of the band A working
within the recessed end A¹. If two brake rods are employed they preferably
pass at either side of the diagonal pillar D¹ but if one rod only is employed it
may be duplicated at the part where it passes the diagonal pillar; or it may
pass through such pillar, holes being made therein, for it to pass in and out at.
The brake rod or rods may be made adjustable by means of a threaded end F¹
and nuts F provided preferably at the part where such rod or rods join the
brake lever or the brake itself when no lever is employed.
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. The application of a brake to the treadle crank axle of bicycles, tricycles, or
other suitable road vehicles, in the manner and for the purposes, substantially as
shown and described.
2. A brake for the treadle crank axles of bicycles, tricycles, or the like, con-
sisting of a spoon, band or clip A, rod or rods F, connecting quadrants or arms G,
with or without hand grip H, and with or without operating lever E, in the
manner and for the purposes, substantially as shown and described.
3. The combination of the parts to form a brake for the treadle crank axle of
safety bicycles or the like, substantially as described and shown in the accom-
panying specification and drawings.
