Improvements in Brakes for Omnibuses, Vans, and Carriages.
SAMUEL CHANDLER, Senr., Engineer, SAMUEL CHANDLER, Junr., Engineer, &
JOSIAH CHANDLER, Engineers, of The Central Works, Kennington Oval,
London, S.E., do hereby declare the nature of this invention to be as follows:-
We provide a hollow shoe or recepticul for attachment to the ordinary leaver
rods generaly actuated by the foot of the driver-into this shoe or recepticul which
is made of iron or other suitable material is placed a block of suitable wood or
other material for contact with the tyre, into and through the bock of the shoe
is inserted one or more adjusting screws to be used for the purpose of forcing for-
ward the breaking block which works into & out from the shoe telescopicully,
which when in position is fixed so by a screw from the side of the shoe or in any
other convenient place. This invention overcomes the clumsy method & the
frequency of constantly packing & making up adopted on the old system, as the
wear & tear occassioned by contact with the tyre is mechanicully taken up in a
few minutes by the adjusting screw forcing the breaking block forward. Of course
a strip of iron is advantageously placed between the end or ends of the screws and
the block to prevent the screw entering the block when the same is in action
against the tyre.

SAMUEL CHANDLER, Senr., Engineer, SAMUEL CHANDLER, Junr., Engineer, and
JOSIAH CHANDLER, Engineer, of The Central Works, Kennington Oval,
London, S.E., 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:-
We provide a hollow shoe or receptacle for attachment to the ordinary lever
rod generally actuated by the foot of the driver into this shoe or receptacle which
is made of any suitable metal is placed a block of wood or other material for con-
tact with the tyre of the wheel when operated by the driver into and through the
back of the shoe are inserted one or more adjusting screws these screws are for
the purpose of forcing forward the breaking block which works into and out from
TDO37

page_text: the shoe telescopically which when in position is fixed so by a screw from the side
of the shoe. This invention overcome and is intended to supersede the present
clumsy method and the frequency of packing and making up adopted on the
old system as the wear and tear occasioned by contact with the tyre is mechanically
taken up by forcing forward the block by the aforsaid adjusting screws.
A. strip
of metal is placed between the back of the block and the adjusting screw to pre-
vent the screw entering the block by constant pressure from use.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawings.
Figure 1 is a plan of the back of the shoe.
Figure 2 is a side elevation.
Figure 3 is a view of the front.
Figure 4 is an end elevation and Figure 5 is a sectional elevation.
Similar letters of reference indicate corresponding parts in the several figures.
a is the shoe or receptacle into which the block of wood or other material b is
fitted projecting as shewn beyond the face. c are the adjusting screws which operate
against the block when found necessary to force it forward. The screw d is then
screwed in in orderd to secure the block in position the plate e and the screws f are
intended to secure the shoe on to the lever when in slot 9.
Having now particularly described and assertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is;-
1. A break shoc, the block of which shall fit in telescopically capable of being
forced forward by the adjusting screws.
2. In the shoe adjusting screws solely for the purpose of readily forcing the
block into position.
3. For the shoe a screw at the side to fasten block into position when set sub-
stantially as described by reference to the drawings.
