FICATION
The Construction of a Chamber or Receiver to be Coupled to Existing
Blast Furnaces for Smelting Iron from the Ore, and also to New
Furnaces.
I WILLIAM HUTCHINSON of 66 Elizabeth Street, Salford Manchester, in the County
of Lancaster, Engineer do hereby declare the nature of this invention to be as
follows:-
My invention relates principally to the construction of what are called chambers or
receivers to be attached to the present strong hot air blast furnaces for the
manufacture of pig iron. I place the chamber or receiver just below the level of
the bottom of the furnace, which will cause the metal & slag to flow to the chamber
or receiver & thereby the strong hot air blast passing from the furnace through the
passage which couples the chamber or receiver to the furnace, which has the effect
of purifying and toughening of the pig iron, when the chamber is sufficiently filled
with metal, there being a spout attached to the chamber or receiver for tapping out
the metal to be run into which I relate a special pig iron bed, which is provided to
receive the metal to be cast into pigs. A chain creeper or elevator is provided for
removing the pigs; when the meta! is sufficiently set it is then put on the creeper or
elevator & conveyed into trucks or piled into stacks as may be required.
The chamber or receiver is provided with a chimney or an upright boiler with
chimney passing through it for the escape of sulphurous gases from the iron in the
process of purifying.
In the chamber or receiver there will be an overflow for the slag to run from the
top of the iron, from each side of the chamber or receiver.
The passage which couples the furnace & chamber together will be made in two
halves, so as to be repaired whenever required. The advantage in this process is,
there is no metal or slag remains in the furnace, therefore there is a better flow of
metal from the furnace, which prevents the term of scaffolding also a greater quantity
of iron is melted with less quantity of coke.

COMPLETE SPECIFICATION..
The Construction of a Chamber or Receiver to be Coupled to Existing
Blast Furnaces for Smelting Iron from the Ore, and also to New
Furnaces.
1, WILLIAM HUTCHINSON, of 66, Elizabeth Street, Salford, Manchester, in the
County of Lancaster, 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 :-
This invention relates to the construction of a chamber or receiver to be coupled to
existing blast furnaces for smelting iron from the ore, and also to new furnaces.

page_text: And in order that my invention may be more fully understood I have caused to be
appended hereunto one sheet of drawings marked with letters of reference indicating
like parts in the various figures.
Fig. 1 is a vertical cross section, Fig. 2 a plan of a blast furnace constructed
or provided with my improvements, and Fig. 3 a detached view showing a
modification thereof.
a is a blast furnace, the chamber or receiver coupled thereto, c the pig bed,
d a creeper and e a truck.
In carrying out my invention and referring to Figs. 1 & 2, I combine or couple
with the blast furnace a, which is of the usual construction, a chamber b, serving to
receive the metal previous to it being run into the pig bed c. The bottom of this
chamber or receiver is arranged below the level of the bottom of the furnace a and
a channel between the same, slightly declining from the bottom of the furnace a
through which channel the metal and slag is allowed to flow into the chamber or
receiver b. During the flow into the latter the metal carries with it a strong hot air
blast which has the effect of purifying and toughening the pig iron. The channel fis
formed in balves, the top half being rendered removable so as to facilitate repairs
wlien required. The chamber or receiver b is formed with a chimney through
which chimney the sulphurous gases evolving from the metal during the process of
purifying can escape. In the side of the chamber or receiver b are formed
openings through which the slag on the surface of the metal in the chamber or
receiver can overflow or may be racked out. The chamber or receiver b is also
formed with a spout 6 which when tapped conveys the metal into the bed e where
it is cast into pigs. After the metal in the said bed has sufficiently set, the pigs cast,
are placed onto the creeper d and thereby conveyed into the truck e or from whence
they can be piled into stacks as may be required.
A modification of my invention consists in forming around the chamber or receiver
chimney b', see Fig. 3, a boiler g whereby water may be heated and steam generated
for various uses.
The great advantage derived from my improved blast furnace described, is that
no metal or slag remain in the furnace and thus a better flow of metal is obtained
which prevents what is technically known as "scaffolding" and whereby a greater
quantity of metal can be smelted with less quantity of coke than heretofore has
been the case.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim, is―
1st. In combination with a furnace for smelting iron from the ore, a chamber
connected or coupled thereto by means of a channel f and adapted to receive the metal
from the furnace a previous to it being run into the pig bed c, all substantially
as and for the purpose set forth.
2nd. The chamber or receiver, specified in the preceding claim, formed with a
chimney for the escape of the sulphurous gases, all substantially as set forth.
3rd. The general construction and arrangement of parts constituting my
improvements operating substantially as and for the purpose set forth.
Dated this 7th day of December 1896.
