dispense with the present system of sawing.
The said appliance is a cast or solid steel block referred to in drawing as Fig. 1
with a recess on the surface to take a hard steel cutter referred to as 2 B, which
is secured to the block by screw bolts marked 2 C.
The punch or cutter is fitted and secured in the working part of the said
punching or shearing machine.

WILLIAM WALLACE HUNTER, Merchant, Regent Street, New Swindon, Wilts,
WILLIAM MATTHEW MITCHELL, Ship Builder, 199, Luton Road, Chatham, Kent,
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:-
The said appliance is a tool that can be used with any punching or shearing
machine for cutting iron or steel bars of any bevel to any bevel, in order to
dispense with the present system of sawing.

page_text: The said appliance is a solid, or cast steel block 3 ins. deep 4 ins. wide 6 ins.
long with a flange each side 1½ ins. wide with 4 holes one at each corner which is
for fixing the block to the machine when in use. The block (1) on drawings filed
with the Provisional Specification 4 ins. from the end shown at the top of Fig. (1)
it rises 2 ins. above the flange and inclines to the centre of the block as shown on
block (1) Fig. 3 and then lengthens so that the centre of the block is 4 ins.
long, being in. longer than the side portion. The centre of this block from of
an inch from the edge is a recess in. deep cut level, in which is fitted in two
pieces joining at the top of recess a hard steel cutter, which is secured to the
block by means of four screws one at each corner. In the centre of this cutter
is another recess, commencing 2 ins. from the end shown at the top of 2 B, Fig. 1.
and continuing the whole length of the cutter, it is in. wide at the surface
and 2 ins. deep widening from in. on the surface to ins. at the bottom see
block (1) Fig. 3, 21). From the 4 ins. given as the length of this part of the
block, it rises from the flange in. and 1½ ins. wide tapering to in. at the centre,
then to make the block the full length, viz. 6 ins. it rises again
from the flange 2 ins. and in. wide widening to 1 ins. at the centre,
this portion of the block has a flat surface see block (1) Fig. 3, 2 E. There is a
cavity formed by a continuation of the widest part of the centre recess ins. from
the bottom of its extreme depth of 2-ins straight through the lower end of
Fig. for the waste iron to pass from. The block is then fastened to a punching
or shearing machine. The iron is laid across the centre recess in an horizontal
position at the angle required.
The punch hereafter described is brought to bear upon the iron and is forced
through into the centre recess cutting out a piece the size of the punch which
falls out at lower end of Fig. 1. The punch is a piece of hard steel with a blade
2 ins. wide and in. thick and 2 in. long the top of the blade runs into a round
piece of steel 1 in. in diameter and extends for 2 ins. at this point it is turned
down to 1 in. forming a sholder and made yet another 2 in. longer so that it can
be fitted into the machine in which it is to be used.

Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is :-
-
1. In appliances for cutting zede, tees or angle bars to the required bevel, the
employment of a block having a recess in connection with angular openings in com-
bination with a cutting tool or punch for the purpose of enabling the desired zeds,
tees or angle bars to be cut to the required bevel, substantially as described and
illustrated herein and for the purpose set forth.
