NOW KNOW YE, that we, the said George Hartshorne, the younger,
Daniel Grainger Ward, and William Woolley, do hereby declare the nature
of our said Invention, and..in what: manner the same is to be performed; to
be particularly described and ascertained in and by the following statement,
reference being had to the Drawings hereunto annexed; and to the letters
and figures marked thereon (that is to say):
A.
Our Invention refers to the manufacture of perforated iron or metal plates
or sheets used for granaries and other like purposes; and also in thinner
material and other metals for various uses, such as perforated blinds or lattice,
and in working our Invention, we proceed as follows:-We make two metal
plates, termed he and she plates; the he plate is furnished with a number of
pegs or projections standing up from its surface; the she plate is made with
a corresponding number of holes or sinkings. The plate or sheet of metal to
be pierced is then placed between. these plates, and all are enclosed between
two plain plates, one on the top and one underneath. The whole of these
plates are then passed between rolls, and by the pressure of the rolls the pegs
or projecting parts pierce the plate, and thus plates with a vast number of
perforations are rapidly and economically produced.
DESCRIPTION OF THE DRAWINGS.
Figure 1 represents a plan of the he plate; Figure 2 being a plan of the
she plate; and Figure 3 a section of all the plates combined, and as they
would appear after being passed through the rolls.
By a reference to these Drawings it will be seen that the he plate, Figure 1,
consists of a plate or bed, made by preference of iron, into which are securely
fixed steel tapered points in any number, and of any requisite size. The she
plate, Figure 2, is sunk with a corresponding number of perforations, so that
when a plate or sheet of metal (A, Figure 3,) is laid between the he and she
plates (X and Y) and the filling plate (B) is laid on the she plate, the
operation of rolling forces the points on the he plate through the plate or sheet
of metal into the perforations in the she plate, as shewn in the Drawing. The
several plates being separated, the perforated sheet or plate can be removed.
The lugs (C, C,) upon the she plate fit into corresponding indentations in the
edge of the he plate, and facilitate the separation of the parts. The form of
the he plate, shewn in the Drawing, requires only one filling plate, as at (b),

page_text: instead of one above and one below the perforating plates, as stated in our
Provisional Specification. It is unnecessary to describe the rolls we employ,
as any ordinary train of rolls. of sufficient strength will answer our purpose.
Having thus described the nature of our said Invention, and the manner
in which the same is to be performed, we claim the improvements in punching
or perforating plates or sheets of metal in the manner. described, and also the
perforating plates or apparatus in conjunction with the process of rolling to
be employed for this purpose, as herein more fully set forth and specified.
In witness whereof, we, the said George Hartshorne, the younger,
Daniel Grainger Ward, and William Woolley, have hereunto set our
hands and seals, this Eighteenth day of September, in the year of
our Lord One thousand eight hundred and sixty-two.
