Nickel, and Cobalt, or their Compounds.
We, JOHN CAMERON, of 99 King Edward Road, South Hackney, in the County of
Middlesex, Chemist, and ALEXANDER MAXWELL GRANT, of 24 Witch Road, Kil-
marnock, in the County of Ayr, Engineer, do hereby declare the nature of this
Invention to be as follows, that is to say :-
Our said Invention has for its object to improve the construction of converters
or furnaces for treating molten metals with air or gases and to render such apparatus
advantageously applicable for purifying silver, copper, nickel, and cobalt, such
metals being in the condition in which they are obtained by primary smelting
operations.
In carrying out our Invention the converter is made in two parts, the lower part
being fixed to a ring supported by means of trunnions through one of which the
air blast passes and from which it is led by a pipe into an air space extending over
the entire bottom of the converter. The bottom air space is enclosed by an outer
iron shell which can be removed to give access to the buyeres, and the space serves
to prevent overheating of the converter bottom. The upper part of the converter is
made in a separate iron shell having an angle-iron flange round its lower edge to be
secured by bolts to a similar angle-iron flange riveted to the shell of the lower part
of the converter. The shape of the upper part of the converter may be varied but
it is by preference made with a contracted throat concentric with the axis of the
converter. The construction of the converter in two parts facilitates the application
and renewal of the lining.

Improvements in Converters or Furnaces for Treating Silver, Copper,
Nickel, and Cobalt, or their Compounds.
We, JOHN CAMERON, of 99 King Edward Road, South Hackney, in the County of
Middlesex, Chomist, and ALEXANDER MAXWELL GRANT, of 24 Witch Road, Kilmar-
nock, in the county of Ayr, Engineer, 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, that is to say :-
Our said Invention has for its object to improve the construction of converters or
furnaces for treating molten metals with air or gases, and to render-such-apparatus-
advantageously applicable for purifying silver, copper, nickel, and cobalt, such
metals being in the condition in which they are obtained by primary smelting
operations.
We, hereunto append two sheets of explanatory drawings to be hereinafter referred
to in describing our improved apparatus, figures, 1, and 2, on sheet, 1, being
sectional side and front elevations, showing the converter in connection with the
cupola from which it receives the metal or metallic compound to be treated. Figures,
3, and 4, on sheet, 2, are an enlarged elevation and an enlarged vertical section of the
In these drawings the same reference letters are used to mark the same

converter.
In carrying out our Invention the converter is made in two parts, A, B, the lower
part, B, being fixed to an iron ring, C, supported by means of trunnions, D, E,
through one, D, of which the blast of air or gas passes, and from which it is led by
an elbow pipe, F, into an air space, G, extending over the entire bottom of the
converter. The bottom air space, G, is enclosed by an outer iron shell, H, which
can be removed to give access to the tuyere holes and the air space also serves to
prevent overheating of the bottom part, B, of the converter.
The blast passes
through an outer box, J, fixed to the air-space shell, H, which is continuous across
the top of the box, J, but is perforated with holes for the passage of the blast.
The box, J, and perforated part of the shell, H, serve to distribute the blast uniformly,
or in whatever way is in practice found best, instead of its being concentrated on
any one part. The tuyere holes, K, are shown as converging towards the interior of
the converter; but they may be disposed in any way that may be found
advantageous, the improved construction facilitating any alterations that may be
desired. Thus, on removing the bottom shell, H, some tuyere holes, K, may be
plugged and others unplugged.
The upper part, A, of the converter is made in a separate iron shell having an
angle-iron flange, L, round its lower edge to be secured by bolts to an annular
plate, M, fixed by means of riveted angle iron, N, to the iron shell of the lower
part, B, of the converter. The shape of the upper part, A, of the converter may be
varied, but it is by preference made, as shown, with a contracted throat concentric
with the axis of. the converter. The construction of the converter in two parts
facilitates the application and renewal of the lining.

page_text: The arrangement of the converter in relation to the cupola, P', and other parts, as
shown in figures, 1, and 2, is convenient for the purpose for which the apparatus is
specially designed. The converter, A B, is set on a platform or terrace, Q, at a
sufficiently low level to receive the molten metal from the cupola, P, when inclined
with its mouth as indicated by the dotted lines, R; whilst at a still lower level, S,
there is a line of rails for trucks, one, T, of which is shown in figure, 1. The truck, T,
carries a mould or moulds suitable for the casting of the purified metal in the
form of horizontal bars or pigs. For the casting operation the converter is inclined
with its mouth down as indicated by the dotted lines, U.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
Constructing converters or furnaces for treating silver, copper, nickel, and cobalt,
in the improved manner substantially as hereinbefore described.
