I, JOHN GEORGE HARRISON of Noel Road, Edgbaston, near Birmingham, in the
County of Warwick, Manager of Works, do hereby declare the nature of said
invention for "IMPROVEMENTS IN THE MANUFACTURE OR PRODUCTION OF BRAKE
IRONWORK FOR WHEELED VEHICLES," to be as follows:-
My invention copsists in the improvements hereinafter described in the manu-
facture or production of brake iron-work for wheeled vehicles, the said improvements
having for their object the production of brake iron-work stamped out from the
solid, so as to greatly reduce the number of welds or shuts, and consequent risk of
fracture; thus in the slotted arrangement, the main body prop is made in one
piece-The wheel end of the main lever, and the inner end of the main lever, also
the socket eye between the two last named, in which the shank or spindle of the
main prop takes are made in one piece. The T mitred wheel flap which is shut
upon the end of the main lever is made in one piece,-also the slotted centre
arrangement which is welded upon the inner end of the main lever, is also made
in one piece.
In the crank centre arrangement (off side) the main prop, the wheel end of the
main lever, the inner end of the main lever and the T wheel flap are made the
same as before--The crank centre piece which is shut upon the inner end of
the main lever, is made in one piece with the bracket eye for carrying the short
end of the crank centre-The said cranked centre piece is produced by being partly
drawn and partly stamped.
The near side of the cranked centre arrangement is also partly drawn and partly
stamped as last described.
The rolling bar arrangement consists of a spindle reduced in diameter at one end,
and having a collar at the junctions of the parts of two diameters, and standing
perpendicular to the enlarged part a lever or spur is made therewith or attached
thereto by welding-The end of reduced diameter welded to a plain bar or when
made solid is drawn down while the end of larger diameter is welded to the
L wheel flap-The spindle of two diameters, its collar and the perpendicular lever
are stamped out of the solid, so is also the L wheel Hap shut upon one end; and
upon the collar of the spindle last named, a bearing for roller bar takes-This
bearing which may be straight or L formed-The handle piece with its eye, and

page_text: square or round hole within its side is also made in one piece-Also the handle arch
piece with its bossed eye centre, for carrying attachment bracket plate and spindle
is made in one piece, so is also the bracket plate and its spindle.
The body of the main prop herein before described is produced from a straight
piece of metal which is slit or divided partially down its middle in the direction of
its length, the split terminating in a slight enlargement-The sides of the divided
part is turned down at right angles so as to form the T or main body of the prop,
while the other or unslitted part is fashioned into the shank-The T wheel flap
and rolling bar and spur arch piece bracket flap hereinbefore described is produced
exactly in the same way, other than the mitred or other parts are fashioned to the
shape required, thus the metal in forming the L flap would be round to an angle-
The main lever and the inner end of the main lever and bossed eye bracket of both
the slotted centre and crank centre (off and near side) arrangements are produced
or fashioned by stamping out of the solid metal-The slotted centre piece on the
inner end of the main lever, or the cranked centre piece and the L wheel flap, and
the bearing for roller bar, whether straight or L form and the other parts before
named are made out of the solid metal by stamping and the several parts shut
together in their respective positions.
I wish it to be observed that although I bave described that the foregoing parts
are stamped solid from one piece of metal, yet the said parts may be made out of
more than one piece, although the main object of my invention is to reduce the
number of parts and to produce the parts by stamping them solid.
By my invention, the iron-work of brakes is made more safe, and less liable to
fracture or part when in use, as is so common with brake iron-work made by the
old method of manufacture.
Dated this sixteenth day of March 1885.

page_text: Improvements in the Manufacture or Production of Certain
Parts of Brake Ironwork for Wheeled Vehicles.
I, JOHN GEORGE HARRISON of Noel Road, Edgbaston near Birmingham, in the
County of Warwick Manager of Works, do hereby declare the nature of said
invention for "IMPROVEMENTS IN THE MANUFACTURE OR PRODUCTION OF CERTAIN
PARTS OF BRAKE IRONWORK FOR WHEELED VEHICLES," and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement:-
My invention consists in the improvements hereinafter described in the manu-
facture or production of certain parts of brake iron work for wheeled vehicles, the
said improvements having for their object the production of brake ironwork
stamped out from the solid, so as to greatly reduce the number of welds or shuts,
and consequent risk of fracture; thus in the slotted centre arrangement, the main
body prop is made in one piece. The wheel end of the main lever, and the inner
end of the said main lever, also the socket eye between the two last named, in
which the shank or spindle of the main prop takes, are made in one piece. The
T mitred wheel flap, which is shut upon one end of the main lever, is made
in one piece, also the slotted centre arrangement, which is welded upon the inner
end of the main lever, is also made in one piece.
In the crank centre arrangement; (offside) the main prop, the wheel end of the
main lever, the inner of the main lever, and the T wheel flap are all made the same
way as before described. The crank centre piece, which is shut upon the inner
end of the main lever, is made in one piece with the bossed eye for carrying the
short end of the crank centre.
The said cranked centre piece is produced, by being partly drawn and partly
stamped.
The near side of the cranked centre arrangement is also partly drawn and partly
stamped as last described.
The rolling bar arrangement consists of a spindle reduced in diameter at one end,
and having a collar at the junctions of the parts of two diameters; and standing
perpendicular to the enlarged part, a lever or spur is made therewith, or attached
thereto by welding. The end of reduced diameter is welded to a plain bar, or
when made solid is drawn down; while the end of larger diameter is welded to
the L wheel flap. The spindle of two diameters, its collar, and the perpendicular
arm are stamped out of the solid; so also is the wheel flap shut upon one end;
and upon the collar of the spindle last named, a bearing for roller bar takes. This
bearing may be straight or L formed.
The handle piece with its eye, and square or round hole within its side, is also
made in one piece. Also the handle arch piece with its bossed eye centre, for
carrying attachment bracket plate, and spindle, is made in one piece.
The body of the main prop hereinbefore described, is produced from a straight
piece of metal, which is slit or divided partially down its middle in the direction
of its length, the split terminating in a slight enlargement. The sides of the

page_text: divided part are turned down at right angles so as to form the T or main body of
the prop, while the other or unslitted part fashioned into the shank. The
Twheel flap, and rolling bar and spur handle arch piece bracket flap hereinbefore
. described, are produced exactly in the same way, other than the mitred or other
parts are fashioned to the shape required. The metal in forming the L flap would
be round to an angle. The main lever and the inner end of the main lever and
bossed eye bracket, of both the slotted centre, and crank centre (off and near side)
arrangements are produced or fashioned by stamping out of the solid metal. The
slotted centre piece on the inner end of the main lever or the cranked centre piece
and the wheel flap, and the bearing for roller bar, whether straight or L form
and the other parts before named are made out of the solid metal by stamping and
the several parts shut together in their respective positions.
I wish it to be observed that although I have described that the foregoing parts
are stamped solid from one piece of metal, yet the said parts may be made out of
more than one piece, although the main object of my invention is to reduce the
number of parts, and to produce the parts by stamping them solid.
By my invention, the iron work of brakes is made more safe, and less liable to
fracture or part when in use, as is common with brake ironwork made by the
old method of manufacture.
I will now proceed to describe with reference to the accompanying Drawings,
the manner in which the same is to be performed.
Figure 1 represents in front elevation, the offside slotted centre action or
arrangement, which is fashioned by part drawing and part stamping, produced
from the blank figure 2, which is shown in side elevation figure 3. This blank is
shaped from a flat strip of of metal of the breadth of the broader part, and
reduced in breadth at the shank part, by roughly stamping; which roughly
stamped blank is afterwards finished and the slotted centre arrangement figure 1
thereby produced.
Figures 4 and 5 represent in front and side elevations, the near side of the
slotted centre arrangement, also produced from the blank like unto figure 5.
This said near side is shut or welded upon the offside lever.
The eyes or piercings in the expanded parts may be either slotted or simple holes
of any required shape.
Figure 6 represents in side elevation the T or main body prop produced from a
bar or rod of iron which is partially split longitudinally and the arms or divided
parts produced thereby, are turned down at right angles to the prop or shank part;
that is, a bar or rod is taken and partially slit longitudinally, as represented in
figure 7, the said slit or split terminating in an enlargement which prevents the
split extending itself, on the turning down of the arms or divided sides. Figure 8
shows how the arms are opened out before the final flattening, the whole of the
fashioning is produced other than the slitting, by partly drawing and partly
stamping.
Figure 9 shows the wheel end of the main lever, produced from a hooked end
blank figure 10, a portion of which is shown in elevation figure 11. This hooked
or turned end is slit or divided crosswise, to a suitable distance up the body of the
turned or hooked part; which said slit terminates in an enlargement as before
described with respect to figure 7. The sides of the slit part are then opened out
and flattened down, producing the wheel end or cross piece at right angles to the
stem, as shown at figure 12; the blank figure 12 is then operated upon by
stamping tools, which shape or form it into a finished, mitred T or wheel flap
figure 9.
Figure 13 represents the main lever produced by stamping from the roughly
stamped and fashioned blank figure 14; that is, a rough blank figure 14, partly
stamped and partly drawn and then operated upon by stamping tools, which is
fashioned and shaped into the finished main lever figure 13 with a bossed eye, at
or about its middle, the hole of which is made to receive the shank of the main
body prop figure 6.

page_text: The left hand end of the said main lever is shut upon the end of the mitred
wheel or T flap figure 9, and the right hand end is shut or welded upon the inner
end of the crank centre arrangement of the main lever figure 15. This said
figure 15 which is called the long end of the crank centre (which is shut upon the
near side of the main lever as stated) is produced from the roughly formed blank
figure 16, fashioned by partly drawing and partly stamping. Thus the blank
figure 16 is operated upon by stamping tools and fashioned into the crank centre
arrangement figure 15 with its bossed eyes, one at its end, and the other at or
about its middle.
Figure 17 shows the short end of the cranked centre action, fashioned and
stamped from the blank figure 18. This short end of cranked centre action is shut
upon the end of the offside main lever figure 13 which then constitutes the offside
lever.
Figure 19 shows an L shaped wheel flap which is shut upon the right hand end
of the main lever for another kind of vehicle to which figure 9 is applicable. The
said figure 19 is produced from a roughly formed blank figure 20 produced from a
bar turned hook wise at its end, which turned end is fashioned into the L wheel
end by stamping, and made all in one piece.
Figure 21 is the rolling bar arrangement which consists of a spindle reduced in
diameter at one end, and having a collar or enlargement at the junction of the
parts of dissimilar diameters, and that part which is of smaller diameter, is provided
with a spur which stands perpendicular to the axis of the bar. This rolling bar is
produced from a blank or bar of iron which is first roughly produced, by combined
processes of drawing and stamping, and slit partially down its middle, leaving the
one side with more metal than that of the other. The side a with less metal as
represented in figure 22, forms the spur b, while the side c forms the bar & which is
produced as aforesaid by partially splitting the bar longitudinally, and then turning
the part a at right angles to the part c when the whole is operated upon by dies
worked in a stamp, which fashion the roughly formed blank into the rolling bar
figure 21. Figure 23 is a side elevation of figure 22.
The spur end of the spindle d is welded to the end of the L wheel flap figure 19.
The other side of the rolling bar may if necessary be welded below the collar to
another bar instead of stamping the whole length.
Figure 24 represents in front elevation, and figure 25 in side elevation, a handle
piece made according to my invention, stamped from the blank figure 26. Thus
the bossed eye and the shank of the handle piece, is stamped out from the said
roughly shaped blank figure 26.
Figure 27 is an attachment bracket stamped from the roughly formed blank
figure 28.
The eye of this attachment bracket fits upon the collar of the handle arch piece
figure 29, which said figure 29 of which figure 30 is a plan, is fashioned from a bar
of iron which is first shaped by stamping and then partially slit down its middle,
as represented in figure 31. The sides of the split or divided part of the roughly
formed blank are then turned down at right angles to the shank as shown in plan
and side elevation figures 32 and 33. Thus a roughly formed stamped blank is
split or divided, and then turned down to form the top or T part, when the whole
is subsequently operated upon by stamping expedients and fashioned into the
handle arch piece figure 29.
Figure 34 represents the bearing bracket for roller bar made according to my
invention and formed by stamping, and fashioned from the roughly formed blank
figure 35. The eye of this bearing fits on the boss next to the collar on the rolling
bar figure 21 while a shank is bolted to the underside of the body of a carriage.
The stamping of the parts of brake iron work herein before described, is effected
between half dies or shaping tools of the counter-part of the blanks or work to be
fashioned or formed.
I wish it to be understood that the whole of the brake ironwork hereinbefore
described and illustrated arc respectively stamped, drawn and produced solid from

page_text: one piece of metal, thereby minimising the liability to fracture, from the fact of
being made from one piece of metal.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
Making or producing the parts of brake iron-work solid or from one piece of
metal without shuts or welds, by the processes of stamping, slitting and subsequent
restamping for final shaping; or by the combined processes of drawing down,
stamping, slitting and subsequent restamping for final shaping. Each process, or
the combination of processes as set forth, being conducted and carried out in the
manner, substantially as described and illustrated.
