Year: 1885

Carriage Builder and Job Master do bereby declare the nature of the said invention
for "IMPROVEMENTS IN CARRIAGE BRAKES to be as follows
1
My Invention relates to improvements in brakes for carriages and it has for its
object to enable the brake block to be readily adjusted towards the wheel tyre to
compensate for wear of the block and to be easily replaced when worn out and also
to enable them to be adjusted laterally in case the brake blocks are for any reason
out of truth with the wheel tyre
The Invention consists in securing the brake block to the usual Ṭ shaped lever
of the brake by means of a holder within which the block is clamped and which is
itself secured to the T lever by bolts passing through slots so as to admit of the
desired adjustments the holder itself being expansible if desired to admit blocks of
various sizes or having a hinged side or sides to allow of the block being easily
inserted
The block holder 18 preferably made in two parts each cheek or jaw being
carried by a back plate and the two back plates overlapping one another and being
slotted transversely to receive the bolts securing the two parts to the T lever with
the desired facility for lateral adjustment.
The two back plates can also slide over one another to admit blocks of
different sizes,
If it is not desired to admit of this variation of width the two cheeks or jaws
would be attached to the same back plate one cheek being hinged thereto to
facilitate placing the block in the holder The cheeks or jaws of the holder are
also slotted transversely to receive balts passing through the block from side
to aide the inner sides of the jaws being of extra thickness at the points where
the slots are situated and the block if of hard material being recessed at the
corresponding points
An end piece is provided at one or both ends to enclose the vacant space left
behind the block when it is adjusted for wear and keep out dirt.

page_text: I GEORGE OSBORNE of 135, London Road, Southborough in the County of Kent,
Carriage Builder, and Job-Master, 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
My Invention relates to improvements in Brakes for Carriages, and it has for its
object to enable the brake-block to be readily adjusted towards the wheel-tyre, to
compensate for wear of the block, and to be easily replaced when worn out, and
also to enable it to be adjusted laterally in case the brake block 18 out of truth
with the wheel-tyre The Invention consists in securing the brake block to the
usual Tended lever of the brake by means of a holder which may be expansible,
if desired, to admit blocks of various widths and which is so mounted as to admit
of the desired adjustments
Reference is to be had to the accompanying drawings forming part of this
Specification, wherein Figure 1 is a side elevation, Figure 2 a rear elevation
partly broken away, Figure 3 a plan, and Figure 4 a horizontal section on
line 1-1. Figure 1 of my improved brake-block attachment, Figure 5 is a
front view of the holder with the brake-block removed, and showing the holder
expanded and Figures 6 and 7 show a side elevation and plan, of a modification
The same letters of reference indicate similar parts in all the Figures
The block-holder is made of iron, and preferably in two separate parts a bas
shown, forming cheeks or jaws between which the brake-block c is clamped The
cheeks or jaws, ab are carried by back plates a¹ 61 which overlap one another,
and are slotted at d to receive the bolts e which secure the two parts a b to
the Tended lever ƒ The slots d are oblong in the transverse direction, to enable
the width between the cheeks to be altered, to suit blocks of different widths and
also to admit of the entire holder being adjusted laterally upon the lever f, to suit
the position of the wheel The side-cheeks a b of the holder also have transverse
slots g to receive bolts h which pass through holes in the block c from side to side
The oblong form of these slots g enables the block c to be adjusted for wear
inner sides of the cheeks a bare preferably made of extra thickness at the points
where the slots are situated, and the block c, if of hard material is correspondingly
recessed One of the cheeks a is provided with an end piece at one, or both,
ends to conceal the gap left behind the block c when it is adjusted for wear, and
to keep out dirt Figures 6 and 7 show a modification, in which no provision 18
made for varying the width of the block c In this case the cheek a is attached to
a back plate a¹ as before, and the other cheek b 18 hinged to the same plate
at b* to facilitate placing the block in the holder In other respects, the mode of
fixing the block in the holder and of securing the latter to the brake-lever fare
the same as before described The block c may be of cast iron, hard wood, india
rubber, or composition of india rubber and other materials as now used
The

page_text: 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 carriage brake, the combination with the brake-block, and with the
brake lever, of a block holder having transversely slotted sides and back, for
bolting the block in the holder and the holder to the brake lever, with the necessary
freedom for adjustment for wear and otherwise, substantially as described and
shown in the drawings.
2 A carriage brake-block-holder, constructed of two separate parts, each com-
posed of a side cheek and back plate, both tranversely slotted for bolting to the
block and brake-lever, as shown and described, and for the purposes specified
3 A carriage brake-block holder constructed of one fixed cheek, and back plate,
and one hinged cheek, all slotted for bolting to the block and brake-lever, as
described and shown in the drawings,
