JOSEPH WESTWOOD and ROBERT BAILLIE, both of the London Yard, Poplar, in the

"
AND PUNCHING VERTICAL AND HORIZONTAL HOLES IN STEEL AND IRON PLATES
FOR RAILWAY SLEEPERS,"
Our invention has for its object the stamping or bending of plates or sleepers and
afterwards punching vertical and horizontal holes in railway sleepers by one and
the same machine.
For this purpose the machine consists of a pair of cast iron blocks or stampers
of the form required to produce the sleepers, the upper block being concave and the
lower one convex. The upper block contains or carries punches adapted to punch
the vertical holes in the upper part of the sleeper, and it has also punches to punch
horizontal holes through the sides of the same.
The punches for acting on the upper part of the sleeper are brought in contact
with the fixed or immoveable head of the machine in order to produce the
punching as required.
The punches for acting on the sides of the sleeper are worked by means of
two arms being fixed at the outer ends to lugs on the head of the machine, and
the operation of punching is effected by the vertical movement of the blocks or
stampers.

page_text: The lower block contains all the dies and passages cored out to receive the burrs
which can fall through as required.
The operation of the parts in combination is as follows:-First the plate to form
the sleeper is bent to the shape required, then the lower block is caused to descend,
when the plate to be dished is inserted between the blocks. The two blocks are
then pressed one into the other with the plate between them to which they are
thereby caused to give the form required, a further movement of the blocks brings
the top punches in contact with the plate and punches the holes vertically in the
upper part thereof, and by the same movement the side punches are forced through
the plate and punch the side holes horizontally therein.

AND PUNCHING VERTICAL AND HORIZONTAL HOLES IN STEEL AND IRON PLATES
FOR RAILWAY SLEEPERS
"
Our Invention of "Improvements in Machines for stamping and punching
vertical and horizontal holes in steel and iron plates for railway sleepers" relates
to a machine for stamping and punching vertical and horizontal holes at one
operation or in one and the same machine, and consists of a pair of cast iron blocks
with an arrangement of rods and punches in connection with an ordinary hydraulic
press the lower block being in connection with the hydraulic ram and the upper
block in connection with the cross head of the machine. The vertical and hori-
zontal punches are contained in the upper block and are caused to perform the
punching either when the plate is stamped or afterwards.
The mode of operation is as follows. The blocks are separated by the ram
being at the bottom of the cylinder, the iron or steel plate is made red hot (or it
may be cold) and placed on the top of the lower block when it is forced into the
top block by hydraulic pressure and the plate is stamped thereby; and when the
punching is required to be performed after the stamping the pressure is relieved
for the purpose of withdrawing a forked rod which had been inserted between the
top block and the upper cross head the pressure is then continued which brings
the vertical punches in contact with the fixed or stationary cross head and punches
the vertical holes and at the same time the horizontal punches are caused to punch
the horizontal holes by means of the rods connected therewith one end of each
being fixed to the top block. The stamping and punching having been performed
the pressure is relieved and the lower block descends bringing down with it two.
rods which pass through the upper block and force the stamped plate off the upper
punches. The blocks are shewn for stamping what are called bowl or pot sleepers
for railway rails but they can be varied in form for other purposes where stamping
and punching vertical and horizontal holes are required.
Having thus stated the nature of our Invention we will proceed to describe
more particularly in what manner the same is to be performed by reference to
the accompanying drawing, in which are represented the parts of the machine
above referred to
Fig 1 is an elevation of the machine and section of the stamping and punching
blocks; Fig: 2 a section taken through the line A'. B. and Fig: 3 a section taken
through the line C¹. D'.
The machine for giving the required pressure for stamping and punching
consists of a top and bottom cross head A and B and columns C and D and
hydraulic cylinder E as usual in hydraulic presses. The lower cast iron block G
intended to give form to the plate is fixed on the top of the casting K similar to
the top and bottom cross-head and rests on the ram of the hydraulic cylinder E
the columns answer as guides to ensure a vertical movement of the parts as
required. The lower block G has steel dies let in as shewn.
The upper cast iron block H also intended to give form to the plate, is mounted
ou four bolts attached to the underside of the cross-head (but not fixed thereto) it

page_text: having a motion in a vertical direction to produce the punching when the long
forked rod I is withdrawn from between the top block and the under side of the
cross-head The vertical steel punches a. a. a. a are loose in the upper block and
can only perform their office when the forked rod I is withdrawn.
The horizontal steel punches b. b. are connected to fixed pins on the underside
of the cross-head by the arms J. J. The said punches receive their motion from
the change of position of the arms J. J. caused by the upward movement of the
block H after the forked rod I is withdrawn. But these punches may be worked
by any other suitable means in substitution for the arms J. J.
In order to ensure the plate coming off the vertical punches two rods L. L. fixed
by means of rods or a frame to the casting K pass down through the upper block
and as the ram descends the rods L. L. force the stamped plate off the punches.
The hooked levers M. M. are for the purpose of keeping the blocks G and H.
together while the forked rod I is withdrawn The forked rod I is suspended by a
chain to any convenient part of the building so as to be readily withdrawn and
inserted between the upper block and the cross-head.
The mode of operation is as follows:-The parts of the machine are in the
positions shown in Fig: 1 with the hooked levers M M raised in the dotted
position M¹; when the iron or steel plate (either red hot or cold) is inserted, it
being brought up to four guide pieces N. N. N. N to ensure its being central, when
the pressure is applied and the plate is then stamped, and the parts of the machine
are caused to assume the positions shown by Fig: 2; the hooked levers are then
moved down into the position shewn at M M so as to ensure the holding of the two
blocks G and H together while the pressure is suspended momentarily in order to
admit of the lever I being withdrawn; the pressure is then continued which
brings the blocks G and H up against the cross-head and performs the vertical
and horizontal punching-Or the stamping and punching may be performed
simultaneously in which case the lever I would be dispensed with.
The downward movement of the ram causes the horizontal punches to be
withdrawn and brings down the rods L L and forces the plate off the vertical
punches.
The burrs punched out of the plate pass through holes in the lower block G, and
down through holes in the casting K (shewn by dotted lines in Fig: 1) where they
drop down clear of the hydraulic cylinder E.
Having thus described the nature of our said Invention and in what manner
the same is to be performed we hereby declare that we do not claim as of our
Invention any of the parts above described except when used in combination as
and for the purpose or purposes described. But what we do claim as of our
Invention is: The combination of parts forming or constituting a machine for
stamping and punching vertical and horizontal holes in railway sleepers or plates
at one operation or in one and the same machine in the manner substantially as
herein before described.
In witness whereof we the said Joseph Westwood and Robert Baillie have.
