CERTAIN IMPROVED MACHINES FOR CUTTING OR SHEARING IRON AND OTHER METALS, WHICH IMPROVEMENTS ARE APPLICABLE TO OTHER LIKE PURPOSES
Year: 1843

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
MURRAY GLADSTONE, of Swan Garden Iron Works, Wolverhampton, Iron
Master, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by
Her Letters Patent under the Great Seal of Great Britain bearing date
at Westminster, the Twenty-eighth day of December, in the seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Murray Gladstone, my exors, adñiors, and assigns, Her
especial licence, full power, sole privilege and authority, that I, the said Thomas
Murray Gladstone, my exors, adññors, and assigns, and such others as I, the
said Thomas Murray Gladstone, my exors, adiñors, or assigns, should at any
time agree with, and no others, from time to time and at all times there-
after, during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within that part of Her Majesty's United
Kingdom of Great Britain and Ireland called England, Her Dominion of
Wales, and the Town of Berwick-upon-Tweed, my Invention of "CERTAIN
IMPROVED MACHINES FOR CUTTING OR SHEARING IRON AND OTHER METALS, WHICH
IMPROVEMENTS ARE APPLICABLE TO OTHER LIKE PURPOSES;" in which said Letters
Patent there is contained a proviso that I, the said Thomas Murray Gladstone,
shall cause a particular description of the nature of my said Invention, and
in what manner the same is to be performed, under my hand and seal, to be
inrolled in Her Majesty's High Court of Chancery within six calendar.

page_text: months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being thereunto had, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Murray Gladstone, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are fully
ascertained and described in and by the following Specification thereof, refer-
ence being had to the Drawings hereunto annexed, that is to say:-
Figure 1 represents a front elevation of a double machine for cutting or
shearing iron and other metals of my improved construction; Figure 2 a back
elevation of the same; Figures 3 and 4 two end views; and Figure 6 a plan.
A is the bed plate; B is a main standard for the support of the axis of the
shear blade, which is cast of the same piece with the bed plate; C is a back
standard for the like purpose, which is in a separate piece from the bed plate
but dovetailed into and screwed down upon it. D is the shear blade, which
turns on an axis, supported by the two standards B and C, the heft or arm of
the blade passing down through an orifice in the bed plate to the crank E,
which connects it to the moving power. A view of this blade detached from
the rest of the machine is given in Figure 5. F is a cutting standard, placed
a little way in advance of the main standard B, and dovetailed into and screwed
down to the bed plate in the same manner as the back standard C. The shear
blade has two steel knife edges m¹ and n¹ screwed to it in front and behind
the former of which works against a similar knife edge m² screwed to the inner
face of the cutting standard F, and the latter against a similar knife edge n
screwed to the inner face of the main standard B. The sheet of iron or other
metal is first passed under the cutting edges m' and m² and moved along the
top of the standard F. As the cutting proceeds, the scrap, instead of curling up
as usual, is kept by the projecting piece p (tinted red) of the shear blade quite
flat, and when cut off it falls down through the space between the standards F
and B on to the delivery plate G. A thin strip of metal q, which is screwed to
the inner face of the stand F behind the knife edge m³, and raised a very little
way above the top of that standard, serves to keep the scrap, during the pro-
cess of cutting, separate from the sheet of metal from which it is detached. The
scrap is then (if required) passed crosswise under the cutting edges n' and n²,
in order to cut it into given lengths. II is a roller guide, supported on two
uprights, on which the scrap is rested as it is about to be passed under the
knife edges n¹ and 122, and I is a moveable stop by which the lengths into which
the scrap is to be cut are determined; this stop fitting by an eye on a bar pro-
jecting from the front of the standard F, and being fixed at any part of that bar

page_text: by the wedge pin w, and the scrap being pushed forward to it when passed
under the cutting edges n¹ and n³. The machine is represented in the
Drawings as being worked from below, but it may be readily modified so as to
be equally well worked from above or from either end. It may also be con-
structed with one set only of knife edges, as m¹, m³, or n¹, n²; and besides
cutting or shearing iron and other metals, it may be usefully applied in all
cases where metals have to be divided or pared by clipping.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that what I claim as improve-
ments in the before-described machine or machines are, firstly, the construction
of the shear blade with the projecting piece p; and, secondly, the addition of
the cutting standard F, placed at a short distance in advance of the main
standard B.
THO MURRAY (L.S.) GLADSTONE.
AND BE IT REMEMBERED, that on the Twentieth day of June, in the
year of our Lord 1844, the aforesaid Thomas Murray Gladstone came before
our said Lady the Queen in Her Chancery, and acknowledged the Specification
aforesaid, and all and every thing therein contained and specified, in form
above written. And also the Specification aforesaid was stamped according
to the tenor of the Statute made for that purpose.
