Improvements in Horse Vehicle Brakes.
I, GEORGE HENRY CROKER, of 18, Bellevue Road, Seacombe, in the County of
Chester, Provender Dealer, do hereby declare the nature of this invention to be as
follows:-
This invention has special reference to brakes of horse vehicles called "floats,"
and other two wheeled vehicles.
This invention will be described as applied to an ordinary "float," i.e. a two
wheeled vehicle with a cranked axle, it being at the same time understood that it is
by simple modifications (and in some cases without modification) applicable to other
two wheeled vehicles. In this special application the brake is made in two parts,
each of which is hinged to, or in connection with a provision on the axle; whilst
the two halves are arranged around the hub or nave of the wheel and are adapted
to bear on and grip same when the brake is applied.
The two halves are caused to approach each other and so bear upon the hub of
the wheel or recede from each other when taking off the brake, by a right and left
hand screwed shaft in connection with same, or equivalent mechanism, said
mechanism being operated from the front or back or other convenient part of the
cart by a hand wheel or like device, said wheel being mounted in a suitable bearing
and connected with the actuating screw or other device through a loose joint con-
nection, to provide for the movement of the brake in relation to the wheel, caused
by the action of the spring of the vehicle to which the axle is fixed.
Suitable supports or bearings may be provided on the spring or axle to support
or carry the actuating screw.
The brake semi-circular hoops (and the hub of the wheel in some cases) may be
provided with suitable material to give the desired frictional effect and wearing
capacity.

Improvements in Horse Vehicle Brakes.
I, GEORGE HENRY CROKER, of 18 Bellevue Road, Seacombe, in the County of
Chester, Provender Dealer, do hereby declare the nature of this invention to be as
follows:-
This invention has special reference to brakes of horse vehicles called "floats,"
and other two wheeled vehicles.
This invention will be described as applied to an ordinary "float,” i.e. a two
wheeled vehicle with a cranked axle, it being at the same time understood that it
is by simple modifications (and in some cases without modification) applicable to
other two wheeled vehicles. In this special application the brake is made in two
parts each of which is hinged to, or in connection with a provision on the axle ;
whilst the two halves are arranged around the hub or nave of the wheel and are
adapted to bear on and grip same when the brake is applied.

page_text: .
The two halves are caused to approach each other and so bear upon the hub of
the wheel or recede from each other when taking off the brake, by a right and
left hand screwed shaft in connection with same, or equivalent mechanism, as a
lever, said mechanism being operated from the front or back or other convenient
part of the cart by a hand wheel or like device, said wheel being mounted on a
suitable bearing and connected with the actuating screw, or other device, through a
loose joint connection to provide for the movement of the brake in relation to the
wheel, caused by the action of the spring of the vehicle to which the axle
is fixed.
Suitable supports or bearings may be provided on the spring or axle to support
or carry the actuating means or device.
The brake semi-circular hoops (and the hub of the wheel in some cases) may
be provided with suitable material to give the desired frictional effect and wearing
capacity.
In the drawings illustrating this invention,
Figure 1 is a side elevation, and Figure 2 an end view, partly in section,
shewing a two wheeled cart, usually called a "float," provided with my
invention.
Figures 3 and 4 show the parts of the brake in detail, in side elevation and
cross section.
The brake shown in Figure 5 in elevation, is adapted to be operated by a screw
mechanism.
Figures 6 and 7 show in sectional elevation and back end view my invention
applied to a hansom cab.
Referring now to the drawings, and more particularly Figures 1 to 4, a is the
hub of a wheel of the cart; b is the axle tree, which, as will be seen, is a cranked
or bent one; c is one of the axles proper on which the wheels revolve; d is the
spring, mounted and resting on the elbow of the axle tree; and e are the brake
straps, with the frictional brake blocks e' on their inner sides.
The braking mechanism connected with the hub is wholly carried by the axle
tree, namely, the brake straps e are carried at their stationary or fixed part by a
pin f, carried on the upright part of the axle tree by a bracket f¹, whilst the
movable part to which the ends of the brake straps e are fastened, and through
which they are moved, is carried by a pin 9, carried in the bracket g¹ fixed on to
the upper side of the spring d. Thus by these means or construction the whole
brake mechanism is not affected by the movement of the body of the vehicle, and
when the axle or wheel moves up or down it moves with them.
The actuating device in Figures 1 to 4, and 6 and 7 is a lever h, having a
T head, to the ends of which the ends of the brake straps e are attached; the
fastening consisting of a pin e² passing through the ends of the straps-which are
gripped and come on both sides of the lever head-and through a hole, slotted and
making an easy fit, in the head, as shown. is a notched rack of ordinary form
with which the lever is made to engage, and by which it is held when the brake is
applied, in the ordinary way. j is a grooved metal ring on the hub of the wheel
on which the brake blocks bear when in action. To apply the brake the lever h
is pressed down, thereby causing the brake bands e to wrap round or about the hub
of the wheel, and bring the blocks e¹ on to the ring on the hub a.
In Figure 5, the two ends of the brake straps e are moved onto and off the hub
of the wheel by a right or left hand threaded rod h, the threads of which work in
nuts k, carried in and by the ends of said brake straps. This rod will be
worked from any convenient part of the vehicle by a wheel carried thereon, and
connected with it by rods or bars, having thereon any known suitable joints, by
which the movement between the body of the vehicle and the braking mechanism
may be provided for.
In the case of a hansom cab with my invention applied to it, shown in Figures 6
and 7, the moving parts connected with the brake strap ends, by which they are
operated, are carried by a rod or shaft g supported in the brackets g'-constituting

page_text: bearings thereto-fastened on the axle tree c. This shaft, g, serves the purpose of
the pins g, shown in and set forth with reference to Figures 1 to 4; as it carries
the actuating means or device of the brake straps. This device in this case is
divided, the heads or parts h', connected with the brake straps, being fixed on and
by the ends of the shaft g, and the lever or arm h being fixed on the shaft g, at a
point between the brackets g'. Both the brackets g' and flare carried on and by
the axle tree, the two being held thereon by plates and bolts k, which clamp the
flanges and 2 of said brackets to it, and also hold the spring, axle tree, and
brackets all together. The lever arm his operated by the driver of the vehicle by
his foot from the box 1, to which it is connected by a rod 12, with a head h³ on its
end. A spring m is used in most cases to lift the lever h, and take and hold the
straps e off the wheel hubs when the brake is not being used. The joints,
connections, or bearings of parts, wherein movement takes place through the
oscillations or vibrations of the body and axle and wheels, should be free, or so
made and formed, as to allow of such movement taking place without the straining
thereof.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a two wheeled horse vehicle, a brake comprising brake straps, supported
from the axle or axle tree, and passing round the sides of the hub wheel or wheels,
and an actuating device, as described, connected to the ends of said straps, and
carried by said axle or axle tree; arranged and operating substantially as herein
set forth and shown in the drawings.
2. The two wheeled horse vehicle brakes, having parts constructed, combined,
and operating, particularly as set forth with reference to and shown in Figures 1 to 4 ;
Figure 5; and Figures 6 and 7 respectively.
