the pan, which has two holes, one top & one at bottom drilled through from side

COMPLETE SPECIFICATION.
An Improved Adjustable Brake-block Pan or Holder.
ALFRED HOPTON 126 Euston Road London Coach Ironmonger 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 is for the purpose of holding brake blocks of various sizes in pans
having one or both sides movable so that either one side or both sides may be screwed
up or adjusted to the block & hold it in position, thus avoiding the risk of breaking
the blocks by driving, and the trouble caused by fitting blocks to the pans.
Further the cost of a back & stem, in addition to the pan, are saved by making the
back (or part to which the pan is usually bolted) with stem & back of pan in one
piece.
Fig. 1 represents the brake pan, the back being taper, & the outer flap or wing
fixed & the inside flap or wing movable. On the inside edge of the back are two
screws top & bottom. The inside flap or wing is adjustable to the thickness or shape
of the back of the block by the two nuts on the screws C. The back of the block D
could be made square or tapered, in the latter case the wider part at the top, so
that it will hold the ordinary tapered back or the square blocks as may be used. My
brake block pan is with the stem at back can be made either in cast, stamped or
forged metal, the movable flap or wing being cast.
Figure 2 represents the pan with both flaps or wings E removable, the bolts F
passing through the back top & bottom as shewn, to adjust the flap to hold a block of
any required size. In this case the two side flaps would be cast & the back with stem
made of forged, stamped or cast metal.
Figure 3 shows the back view of the pan G & stem H. This stem can be altered
to any shape & made to connect on the spindle of the brake, working in any required
position.
Figure 4 represents the adjustable brake pan with the block I fitted.
Having now particularly described & ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
1st. A brake pan with one wing movable to hold various shapes of brake blocks,
tapered or square, with or without dovetail backs & adjustable by screws to various
widths of blocks.

page_text: 2nd. An adjustable brake pan with the two wings movable so as to be adjusted in
like manner.
3rd. A brake pan with adjustable wing or wings with back & stem in one piece or
with stem separate.
