Year: 1873

page_text: LETTERS PATENT to Lawrance. Beesley, William Beesley, and James
Beesley, all of Barrow-in-Furness, in the County of Lancaster, Boiler
Makers, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
PUNCHING AND SHEARING METALS AND CROPPING ANGLE IRON.”“”
Sealed the 9th April 1874, and dated the 28th October 1873.
PROVISIONAL SPECIFICATION left by the said Lawrance Beesley,
William Beesley, and James Beesley at the Office of the Com-
missioners of Patents, with their Petition, on the 28th October 1878.
We, LAWRANCE BEESLEY, WILLIAM BEESLEY, and James BEESLEY,
all of Barrow-in-Furness, in the County of Lancaster, Boiler Makers,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR PUNCHING AND SHEARING METALS AND CROPPING ANGLE IRON," to
be as follows:-
1
This Invention has for its object improvements in machinery for
punching and shearing metals and cropping angle iron, and relates
firstly to the use of a Ț shaped lever having a partially rotating motion
on a suitable shaft or pivots in the upper part of the main body or

page_text: casting of the machine, the necessary motion being communicated to the
said lever at or near the lower end of its vertical arm through the medium
of a cam, eccentric, or other suitable device actuated by means of gearing
arranged at the lower part of the main body or casting of the machine.
The necessary punches or moving shears are carried by the horizontal
arms of the lever. By this arrangement a light machine of great
strength is produced, and we are enabled not only to increase the size of
gap
but also to very considerably reduce the depth of arm or portion of
casting overhanging each gap, thereby materially increasing the working
facilities of the machine.
Our Invention further relates to the use when necessary in combina-
tion with the above lever of arrangements for cropping angle iron. For
this purpose we employ a moving cutter or cutters connected to and
deriving motion from the vertical part of the lever, and provided with
suitable guides so as to cut against a fixed die or dies, or the lever may
be formed above its fulcrum with an extension or part provided with a
suitable moving cutter or cutters arranged to cut against a die or dies
attached to the upper portion of the main casting of the machine.
In machines intended to be used for punching only or for shearing
only we may in some cases substitute an inverted L shaped lever for the
T shaped lever above described, such inverted L shaped lever being
actuated at or near the lower end of its vertical part.
When such machines are intended to be used also for cropping angle
iron we provide the inverted L shaped lever with arrangements for that
purpose similar to those already described with reference to the T shaped
lever.

after the date of the said Letters Patent.
NOW KNOW YE, that I, the said James Beesley, on behalf of the
said Lawrance Beesley and William Beesley, and for myself, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by
the following statement thereof, and the Drawings therein referred to
(that is to say) :-
This Invention has for its object improvements in machinery for
punching and shearing metals and cropping angle iron, and relates
firstly to the use of a T shaped lever having a partially rotating motion
on a suitable shaft or pivots in the upper part of the main body or
casting of the machine, the necessary motion being communicated to
the said lever at or near the lower end of its vertical arm through the
medium of a cam, eccentric, or other suitable device, actuated by means
of gearing arranged at the lower part of the main body or casting of the
machine.
.

page_text: strength is produced, and we are enabled not only to increase the size of
gap but also to very considerably reduce the depth of arm or portion
of casting overhanging each gap, thereby materially increasing the
working facilities of the machine.
· Our Invention further relates to the use when necessary in combina-
tion with the above lever of arrangements for cropping angle iron. For
this purpose we employ a moving cutter or cutters connected to and
deriving motion from the vertical part of the lever, and provided with
suitable guides so as to cut against a fixed die or dies, or the lever
may be formed above its fulcrum with an extension or part provided
with a suitable moving cutter or cutters arranged to cut against a die
or dies attached to the upper portion of the main casting of the
machine.
In machines intended to be used for punching only or for shearing
only we may in some cases substitute an inverted L shaped lever for the 1
Ṭ shaped lever above described, such inverted L shaped lever being
actuated at or near the lower end of its vertical part.
When such machines are intended to be used also for cropping angle
iron we provide the inverted shaped lever with arrangements for that
purpose similar to those already described with reference to the T shaped a
lever.
Such being the nature of our Invention, we will proceed to describe
the manner of carrying the same into practical effect with reference to
the accompanying Drawings, in which Fig. 1 is a sectional elevation of
our improved machine as made with a T shaped lever for punching and a
shearing metals and cropping angle iron; Fig. 2 is a sectional plan in
the line A, B, of Fig. 1 with the T lever removed; Fig. 3 is an elevation
of the punching end of the machine; Fig. 4 is an elevation of the
shearing end of the machine; Fig. 5 is a vertical section of the angle
iron cropping arrangement taken in the line C, D, of Fig. 1; Fig. 6 is a
a horizontal section thereof taken in the line E, F, of Fig. 1.
Fig. 7 is a side elevation of one of the links for connecting the sliding
block of the angle iron cutter to the T lever for effecting the return
stroke.
a is the main frame or casting of the machine formed with two gaps, a
and the thou fau aliasing
With the main

page_text: casting a is a wrought-iron T shaped lever d working on a shaft or pin e
supported by the casting a. The horizontal arm d¹ of the lever enters a
slot in a slide e*, which is provided with a cam worked by a lever on
the outer end of its spindle for throwing the slide in and out of opera-
tion. The spindle passes through a slot in the casting a.
The cam and
slide are shewn in position for punching. The punch 9 is secured in
the boss on the end of the slide e* by set screws (Fig. 3); i is the
guard secured by a screw k; 1, the female die; and m, the hole in the
main frame for the burrs to pass through; n, is a slotted slide worked.
by the horizontal arm d³ of the T shaped lever, and has secured to it by
countersunk screws the top cutter o of the shears, whose bottom blade
or cutter p is secured to the main casting a by bolts with countersunk
heads; q is the sliding block of the angle iron cropping apparatus, which
is thrown in and out of operation by a cam r (shewn out of gear in
Fig. 1), which is worked by a spindle ¹ actuated by a lever outside the
main casting; 8, 81, are two spindles or small gudgeons, the one s passing
through the vertical arm of the lever d, and the other s¹ through the
sliding block q. These spindles at each of their ends are formed with
bearings and suitable collars, and the two spindles are connected together
at the respective sides of the block q by links or straps, as shewn at
Fig. 7, thus connecting the sliding block to the T shaped lever to effect"
the return stoke. The links or straps are slotted at one end so as to
allow the spindle s to work (when the cam r is out of gear) without '
actuating the sliding block; is the top blade secured to the sliding
block q by suitable screws, and is the bottom blade, which is inserted
in a recess formed in the main casting, and secured thereto by suitable
bolts not shown. The links work in the spaces shewn at w in Fig. 5.
u, u¹, are loose doors suitably secured to the main casting a. On removing
these doors access is readily obtained to the sliding block links and other
parts of the cropping apparatus for repairing or other purposes. Suitable
facings are made on the doors and main casting for the sliding block to
work against. The main casting is formed to receive the doors as shewn.
The lower end of the vertical arm of the T shaped lever d is formed with
a slot fitted with a sliding block x, actuated by an eccentric pin y, which
works in the block as shewn. This pin receives motion through suitable
gearing, as shewn, from a shaft y¹ provided with a fly wheel z and fast
and loose pulleys.
.
When constructing machines according to our Invention to be wond

page_text: casting with only one gap, and the lever d with only one horizontal arm,
thus converting it into an inverted L shaped lever, whose horizontal arm
is provided with arrangements for punching or for shearing, as the case
may be. This arrangement will be readily understood without farther
description.
In some cases where it is desired the angle cropping arrangement may
be formed above the slide n worked by the horizontal arm, one blade
being attached to the slide n and the other carried in the main frame by
a suitable arrangement, the angle iron being cropped upwards.
And having now described the nature of the said Invention, and in
what manner the same is to be performed, we hereby declare that we do
not claim any of the several parts above described or referred to when
taken separately or used otherwise than in combination with a T shaped
or an inverted L shaped lever, and we declare our improvements to
consist in and that we claim constructing machines for punehing and
shearing metals and cropping angle iron in which the punching, shearing,
and cropping tools are worked by a Ṭ shaped or an inverted L shaped
lever having a partially rotating motion on a suitable shaft or pivots in
the upper part of the main body or casting of the machine, the necessary
motion being communicated to the said lever at or near the lower end of
its vertical arm, substantially as described and illustrated in the accom-
panying Drawings.
In witness whereof, I, the said James Beesley, have hereunto set
my hand and seal, this Twenty-fourth day of April, in the year
