page_text: LETTERS PATENT to Paul Moore and Paul Moore the younger, of Birming-
ham, in the County of Warwick, Manufacturers, for the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF THE DIES OR DRAW PLATES
USED IN DRAWING WIRE AND TUBES, AND FOR OTHER SIMILAR PURPOSES."-
Partly a communication from abroad by J. J. Eagleton, of New York, in

Sealed the 13th March 1860, and dated the 20th January 1860.
PROVISIONAL SPECIFICATION left by the said Paul Moore and Paul
Moore the younger at the Office of the Commissioners of Patents, with
their Petition, on the 20th January 1860.
We, PAUL MOORE and PAUL MOORE the younger, of Birmingham, in the
County of Warwick, Manufacturers, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF THE DIES OR DRAW PLATES
USED IN DRAWING WIRE AND TUBES, AND FOR OTHER SIMILAR PURPOSES," to be as
follows, that is to say:-
This Invention consists in chill casting dies or draw plates of iron or steel
with plugs or mandrils of the requisite guages to form the holes inserted in the
ingot or mould. The die or draw plate is then chill cast round these plugs,
and thus by withdrawing the plugs after the casting is made, the holes are
formed. By this process, the inner surfaces of the holes are chilled, the holes
being formed whilst the die is in a heated state. The plugs, whether of iron
or steel, are accurately turned in a lathe before being used:

page_text: metal gained by chill casting, by this Invention we form the dies or apertures
simultaneously with the casting of the plate; we use plugs of iron or steel and
of the section and size or guage necessary for the shape and size or guage of
the wire or tube or other article we desire to produce, which plugs are accu-
rately turned in a lathe, if wire or tube or other article of a round section is
desired to be produced, but if a section other than round be required then
the plugs are made by hand, or by any other suitable manner, to produce the
shape desired so as to be perfectly true and uniform; and these plugs being
inserted through holes in the mould or ingot in which the draw plate is to be
cast pass through until their points reach home a short distance into the lid of
the mould as far as may be required, so as to perfect the face of the casting
