IMPROVEMENTS IN FURNACES FOR SMELTING AND MELTING
Year: 1856

page_text: LETTERS PATENT to Joseph Deeley, of Mile End Road, in the County
of Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN FURNACES
FOR SMELTING AND MELTING."
Sealed the 29th May 1857, and dated the 3rd December 1856.
PROVISIONAL SPECIFICATION left by the said Joseph Decley at the
Office of the Commissioners of Patents, with his Petition, on the
3rd December 1856
I, JOSEPH DEELEY, of Mile End Road, in the County of Middlesex,
Engineer, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN FURNACES FOR SMELTING AND MELTING," to be as follows:-
My Invention consists in an improved form of grate, and in a new arrange-
ment of the flues in smelting and melting furnaces. And in melting furnaces it
also consists in feeding the metal to be melted and the coke or other fuol into
separate compartments, instead of mixing both in the same compartment as
now ordinarily done.
In melting furnaces, which I will first proceed to describe, I form them
either double or single, the double being merely a repetition of the parts of
the single furnace, one shaft or chimney being common to both. The grate
is mounted upon rollers which travel upon rails, and the side section of the

page_text: bottom of the grate represents a segment of a circle; the air enters through
the bottom of the grate through an opening in the brickwork of the furnace.
The coke or other fuel is fed through a door opening into a vertical chamber,
at the bottom of which the grate when in position for working is situated. In
a line with the vertical chamber at the bottom of the furnace is a trough
containing water, into which any fuel falls when the grate is drawn back. The
metal to be melted is fed into separate vertical chambers, which lead into one
or more receptacles at bottom, from which it is tapped out in the usual
manner. In front of the grate is a bridge, over which the products of com-
bustion pass and enter into, under, and amongst the metal, and finally enter a
Blue made in the chimney. The flue is bent so as to increase the surface
thereof through which the products have to travel, in order to diffuse and
maintain as much heat as possible, whereby a good draft is secured.
The parts which apply to the smelting furnace are the grate and flues in the
shaft or chimney.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Deeley in the Great Seal Patent Office on the
1st June 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
DEELEY, of Mile End Road, in the County of Middlesex, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of December, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Joseph Deeley, Her special licence that I, the said Joseph Deeley, my
executors, administrators, and assigns, or such others as I, the said Joseph
Deeley, my executors, administrators, and assigns, should at any time agree
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN FURNACES FOR
SMELTING AND MELTING," upon the condition (amongst others) that I, tho said
Joseph Deeley, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same

page_text: was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
NOW KNOW YE, that I, the said Joseph Deeley, do hereby declare
the naturo of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, reference being had to the Drawings hereunto annexed, that
is to say:
My Invention consists in an improved form of grate, and in a new arrange-
ment of the flues in smelting and melting furnaces; it also consists in feeding
the metal and coke or other fuel in one or more compartments, instead of one
only, as is ordinarily done.
In melting furnaces, which I will first proceed to describe, I form them either
double or single, the double being merely a repetition of the parts of a single
furnace, one shaft or chimney being common to both. The air enters through
grate bars fixed in the brickwork on each side of the furnace, and passes through
an opening in the brickwork into the fuel. The coke or other fuel and the
metal to be melted are fed into compartments or chambers, and when melted,
run into one receptacle at the bottom of the furnace, whence it is tapped out
in the usual manner. Each chamber is diminished in width at top above the
charging doors, so as to concentrate the heat at the top of the chambers.
The parts which apply to the smelting furnace are all precisely the same.
as the melting furnace, the only difference is, the chambers in the smelting
furnaces are considerably deeper.
The Drawings hereunto annexed represent the manner in which I carry my
Invention into effect.
Figure 1 is a side elevation, partly in section, of one of my improved double
furnaces; Figure 2 is an end elevation of the same; Figure 3 is a cross
section; Figure 4, a plan, partly in section; and Figure 5, a view, partly in
section, of the upper portion of the shaft or chimney. The same letters of
reference are applied to the same parts in the several Figures. The air enters
through the grate bars A, A, fixed in the brickwork B, B, on each side of the
furnace, and passes through an opening in the brickwork into the fuel, which
is fed with the metal to be melted into the chambers D, D, through the
charging doors D', D. When the metal is melted it runs into the receptacle
E at the bottom of the furnace, whence it is tapped out at F. Each chamber
is diminished at the top, as shewn at G, G, for the purpose before described.
The chambers may be worked either jointly or separately.
And having now described the nature of the said Invention, and in what

page_text: manner the same is to be performed, I declare that I claim the arrangement,
of smelting and melting furnaces in such manner that the. metal and fuel
may be supplied to separate chambers, and when melted, run into a single,
receptacle below, as herein-before described and represented in the Drawings
hereunto annexed.
manner the same is to be performed, I declare that I claim the arrangement,
of smelting and melting furnaces in such manner that the. metal and fuel
may be supplied to separate chambers, and when melted, run into a single
receptacle below, as herein-before described and represented in the Drawings
hereunto annexed.
In witness whereof, I, the. said Joseph Deeley, have hereunto. set my
hand and seal, this Thirtieth day of May, One thousand eight hundred
and fifty-seven.
