PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Brass Wire or other Soft
Metallic Wire.
I, BENJAMIN MOUNTAIN, of Castleford, in the County of York, Nail Manufacturer,
do hereby declare the nature of this invention to be as follows:-
:-
I cast in the brass ring form, preferably in revolving moulds, then place it in a
ring mill and it is reduced in section but enlarged in diameter, it is then cut spirally
the required thickness, and by this means greater length and weight of brass wire can
be obtained than by the present process.
Dated this 21st day of July 1890.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Brass Wire or other Soft
Metallic Wire.
I, BENJAMIN MOUNTAIN, of Castleford, in the County of York, Nail Manufacturer,
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 :-
I cast the brass or other soft metal in ring form in revolving moulds, then place
it in a
"ring mill" where it is reduced in section by rolling but enlarged in
diameter, each ring is then cut spirally in one length the required thickness,
the wire is then drawn to the sizes required in the ordinary wire drawing
machinery.
By this means greater length and weight of brass and other soft metallic wire can
be obtained than by the process now in use; for hitherto has been necessary to cast
the metal in ingots or straight pieces, and to reduce such by ordinary rolling or
drawing.
DESCRIPTION OF DRAWINGS.
Fig. 1, is a sectional side view of my improved apparatus employed for moulding
or casting the metal in ring form.
Fig. 2, is an end elevation, looking at the front of the revolving mould, with guide
trough in section.
A is a revolving mould (carried upon a suitable shaft) and having the loose plate B
which is secured to the said mould by means of bolts C and cotters D, or by other
suitable means, so that it can be easily taken off, or sufficiently removed, in order
to take out the metal ring, and can be easily replaced for moulding the next
ring.
E is a guide trough into which the molten metal (to which is added a little salt) is
poured and from which it runs into the mould through the opening F in the plate B.
The plate B may be hinged or pivotted as preferred.
The mould is revolved at a speed of about 700 revolutions per minute, the
centrifugal force keeping the molten metal equally distributed around the mould
and quickly cooling it; preparatory to pouring in the molten metal the mould is lined
with ground charcoal and oil to prevent the metal sticking.

Having now particularly described and ascertained the nature of my said inven-
ion, and in what manner the same is to be performed, I declare that what I
laim is :-
1. The manufacture of brass or other soft metallic wire, in the manner and for the
purposes such as shown and described.
2. The use and employment of revolving moulds A. with front plates B for forming
rings of brass or other soft metal for the manufacture of metallic wire in the manner
and for the purposes such as shown and described.
