PROVISIONAL SPECIFICATION.
Improvements in Brakes for Cycles and like Vehicles.
I, THOMAS CRANMER EWBANK, Sedgebrook Rectory, Grantham, Clerk in Holy
Orders, do hereby declare the nature of this invention to be as follows:-
Each brake block is made of wood, indiarubber, leather, metal or other suitable
material fixed or hinged to the lower end of a bent lever rocking on an axle secured
to the cycle framing. The upper end of the lever projects above the saddle and
terminates in a pad for male riders, or a curved back rest for female riders, the
upper end of the lever may be hinged or jointed above the axle to fold downwards.
Where a mud guard is employed the block is suitably connected to a fork ended
lever to pass each side of the mud guard and hold the block between it and the
tyre. A male rider pressing upon the handles of the vehicles will move his body
backward to press the brake block on the tyre, a female rider throws herself back
so that her hips or waist operates the brake.

I, THOMAS CRANMER EWBANK, of Sedgebrook Rectory, Grantham, Clerk in Holy
Orders, 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 relates to improvements in brake mechanism for cycles or like
vehicles, and it has for its object to provide mechanism for this purpose, which may
be readily operated by a movement of the body of the rider.
The invention will be best understood by reference to the accompanying drawings
in which
Fig. 1. is a side elevation showing a spoon or block brake constructed according
to my invention, applied to a safety bicycle.
Fig. 2. is a side elevation showing my invention applied to a band brake applied
to the back wheel hub of a safety bicycle.
Fig. 3. is a side elevation showing my invention applied to a brake which acts
on the rim or the sides of the tyre of the back wheel.
Fig. 4. is a cross section taken on line XX of Fig. 3.
Like letters indicate like parts throughout the drawings.
In carrying out this invention the brake spoon or block A (see Fig. 1.) is mounted
on the lower end B¹ of a lever B which latter is pivotted on a transverse axle C
Price 8d1

page_text: secured by clips D or other convenient means to the back legs E of the frame of
the bicycle.
The upper part B2 of the lever B is carried up behind the seat or saddle F to a
suitable height, and its free end is provided with a pad or curved rest G, the
position of which is preferably arranged immediately above and behind the seat or
saddle F as shown.
The part B of the lever B may be formed in two parts, one of which telescopes
within the other as shown, in order that the height of the rest G may be adjusted
relatively to the seat or saddle F.
:
The brake is applied either by the rider moving backwards on the seat or saddle,
and pushing against the rest G with his back, or by a backward movement from
the hips.
For the latter movement the rest may be adjusted in a higher position, relatively
to the saddle, than that shown.
The brake spoon or block A is preferably connected to the end B¹ of the lever B,
by a hinged or knuckle joint A! which will allow of a limited amount of movement,
in order that the block A may adjust itself to the periphery of the wheel. The
lever B is returned to its normal position by a spring B.
When mudguards H are employed the brake spoon or block A is placed between
the said guard and the wheel and the end B of the lever B works in a slot formed
therein, or the lever may be formed with a forked end, the two parts of which are
carried round the edges of the mudguard.
'
In order that the position of the rest G may be adjusted to suit any change in
the position of the seat or saddle F either towards the back or front, the parts B¹ B²
may be formed independently of each other and be hinged together on the axle C,
so that they may be angularly adjusted relatively to each other, suitable provision
being made for securing one part to the other.
In the band brake arrangement shown in Fig. 2. the lower end B₁ of the lever B
is carried forward as shown and is connected by a connecting rod J to the lever J¹
of. a band brake acting on the hub of the back wheel. The band brake may be
of any well known construction and arrangement.
In the rim brake arrangement shown in Fig. 3. and 4., the end B¹ of the lever B
engages in the slotted ends K¹ of two bell-crank levers K, which levers are pivotted
on pins or axles M secured.to or formed integrally with the clips D which carry
the axle C of the main lever B. The lower ends K of the levers K are provided
with preferably leather faced blocks N between which the rim L or the tyre is
gripped when the end B¹ of the lever B is raised.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is:-
-
(1.) In a brake for a cycle or like vehicle arranging the free end of a brake
operating lever such as B in such a position relatively to the seat or saddle F that
said lever may be moved and the brake applied by a movement of the body of the
rider substantially as described.
(2.) In a brake for a cycle or like vehicle the combination with a brake spoon or
block such as A of an operating lever such as B3, B4, 132, the free end 13 of which is
arranged near and is adjustable relatively to the seat or saddle F substantially
as and for the purpose described.
(3.) In a brake for a cycle or like vehicle the combination with rim brake levers
such as K of an operating lever such as B, 131, B2, the free end B2 of which is
arranged near and is adjustable relatively to the seat or saddle F substantially as
and for the purpose described.
(4.) In a brake for a cycle or like vehicle the combination with a band brake or
other frictional device of an operating lever such as B, B1, B2, the free end B2 of
which is arranged near and is adjustable relatively to the seat or saddle F sub-
stantially as and for the purpose described.

page_text: (5.) The combination and arrangement of parts comprising the several complete
brakes for cycles or like vehicles substantially as described and illustrated in the
accompanying drawings.
