PROVISIONAL SPECIFICATION.
Improved Vehicle Brake.
We, HENRY DRAPPER, of 16 Union Street, Borough, in the County of Surrey,
Carman and Contractor, and JOSEPH GRAY, of 41 Darrell Road, East Dulwich,
in the County of Surrey, Wheelwright, do hereby declare the nature of this
invention to be as follows:-
Our invention has for its object an improved brake of simple construction and in
which the shoe may be re-adjusted as its surface is worn away and so arranged
that the end of the grain, when a wooden shoe is used, faces the wheel tyre.
In carrying this invention into practical effect we mount in suitable slides or
roller guides on the bottom of the vehicle on one or both sides thereof, a rod or
slide of square or other section and of a size and length proportional to the size
and weight of the vehicle. One end of this rod or slide has projecting from its
inner side an arm against which works one end of a lever suitably pivoted to the
underside of the vehicle body and connected at its opposite end by a chain, or the
like, to a pedal or lever in the front of the vehicle.
From the same end, but opposite or outside of said rod or slide project two other
arms or a bracket to the ends or face of which is bolted or otherwise secured a
rectangular metal frame. Through this frame slides a flat rectangular block of
wood or other suitable material forming the brake shoe which when suitably
adjusted is secured in position by one or more bolts passing through one or a row
of holes in said wood or other block and the sides of the frame.
To normally retain the side in such a position that the shoe so held is out of
contact with the tyre of the wheel, a V spring is secured to the bottom of the
vehicle body so that the free ends thereof rest against the end of the rod or slide
and a fixed bolt or block respectively.
When the vehicle has already been fitted with a lever having secured on one end
thereof a block and shoe of the ordinary construction, it will be perfectly understood
that the latter may be replaced by a block and shoe constructed according to our
invention.

COMPLETE SPECIFICATION.
Improved Vehicle Brake.
We, HENRY Drapper, of 16 Union Street, Borough, in the County of Surrey,
Carman and Contractor, and JOSEPH GRAY, of 41 Darrell Road, East Dulwich,
in the County of Surrey, Wheelwright, 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 :-
Our invention has for its object an improved brake of simple construction and in
which the shoe may be readjusted as its surface is worn away and so arranged that
the end of the grain, when a wooden shoe is used, faces the wheel tyre.
In carrying this invention into practical effect we mount in suitable slides or
Price Ra]

page_text: roller guides on the bottom of the vehicle at one or both sides thereof or on a
board attached thereto, a rod or slide of square or other section and of a size and
length proportional to the size and weight of the vehicle. This rod or slide has
projecting from its inner side an arm against which works one end of a lever
suitably pivoted to the underside of the vehicle body of the board attached thereto
and connected at its opposite end by a rod, chain or the like, to a pedal or lever in
the front of the vehicle.
(
From the front end of said rod or slide project two other arms or a bracket to
the ends or face of which is bolted or otherwise secured a rectangular metal frame.
Through this frame slides a flat rectangular block of wood or other suitable
material forming the brake shoe which when suitably adjusted is secured in position
by a bolt passing through one of a row of holes in said wood or other block and
through the sides of the frame.
To normally retain the slide in such a position that the shoe is out of contact
with the tyre of the wheel, a V spring is secured to the bottom of the vehicle
body or the board secured thereto, so that the free ends thereof rest against the
projection on the inner side of the rod or slide and a fixed bolt or block
respectively.
And in order that this invention may be more fully understood and carried
into practice we will now proceed to describe the same with reference to the
accompanying drawings, of which
Fig. 1 is a perspective view of the underside of a brake constructed and operated
according to our invention; and Fig. 2 an elevation of the opposite side to the
brake block and shoe to that shown in Fig. 1.
The bar a is mounted to slide longitudinally in guides b c attached to the plate d
secured either directly to the underside of the vehicle or to a board e bolted or
otherwise attached thereto. The front end of this bar a has two arms a' formed
on it and to these the brake block is adjustably secured whilst at one side of said
bar a projecting lug a² is provided against which works one end of a lever f
suitably pivoted either to the underside of the vehicle or to the board e and having
its free end connected by a rod, wire rope, chain or the like to a treadle or other
lever situated at the front or other convenient part of the vehicle.
The movement of the bar a is facilitated by rollers g g one mounted in back end
of said bar and one end in the guide b and it is normally held in a position so that
the brake shoe is out of contact with the wheel tyre by a V spring / secured at
its apex to a plate attached to the underside of the vehicle or to the board e
and having its ends resting respectively against the lug a² and a stop d' on the plate d.
The brake block consists of a frame constructed of an oblong plate m bent to
an U form and an oblong plate n connected together and to the arms a' by screws m¹
mitred on the ends of the plate m, and passing through openings in the plate n and
arms a¹, and nuts o. Through this frame slides a flat rectangular block P of wood
or other material forming the brake shoe which when suitably adjusted is secured
in position by a bolt a passing through one of a row or rows of holes in said block
and through holes in the plates m and n. The brake shoe may thus be adjusted as
it is worn away whilst the brake block may also be adjusted in a direction parallel
to the wheel axis as is often found desirable when the latter has been re-shod by
the insertion or withdrawal of washers between the plate m and arms a¹ on the
screws m¹.
When the vehicle has already been fitted with a lever having secured on one end
thereof a block and shoe of the ordinary construction, it will be perfectly understood
that these latter may be replaced by a block and shoe constructed according to our
invention.
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 :-
•
(4) A vehicle brake consisting essentially of a longitudinally slidino har a

page_text: carrying a brake block and shoe, a lever f and spring such as h arranged and
operating substantially as described and illustrated in the accompanying drawings.
(2) In a vehicle brake a brake block, in the form of an open frame, constructed
of two plates m, n connected together and to the brake arm or lever by screw
5 threaded bolts secured to and projecting from the ends of the plate m and nuts as
and for the purpose described and illustrated in the accompanying drawings.
(3) In a vehicle brake a brake shoe formed of a block of wood or other material
having one or more rows of holes formed therethrough as and for the purpose
described.
