of Steel and other Metals.
JAMES NOBLE Grosvenor Terrace Linthorpe Road Middlesbro on Tees Steel
Works Manager, do hereby declare the nature of this invention to be as
follows:-
(First) In building up the port divisional walls leading out of chambers & forming
gas & air ports, I form a cavity in each wall which is filled up with sand, thereby
avoiding all risk of Gas & air mixing before entering the furnace at mouth of ports
inside furnace.
(Secondly) At the level of floor line I form a pocket or receptacle at the end &
between each port divisional wall to catch the slag or melted brick work that runs from
the port end stopping this can be readly cleaned out at intervals & thus avoid the
choking up of ports in the manner that usually takes place in the ordinary arrangement
of Siemens Martin Regenerative furnaces.

I, JAMES NOBLE, of Grosvenor Terrace, Linthorpe Road; Middlesbrough, in the
County of York, Steel Works Manager, 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 :-
"
My invention relates to an improvement in the construction of the "Siemens
Regenerative Furnace used in the manufacture of steel and other metals; such
improvement consisting in a means for preventing the choking up of the gas and air
ports by melted slag and brickwork, which generally occurs in such furnaces, as
ordinarily constructed.
In the accompanying two sheets of drawings, Fig. 1 is a sectional plan of a
"Siemens" regenerative furnace, through the line X X in Fig. 2, and Fig. 2 is a
longitudinal sectional elevation of the same through the line Y Y in Fig. 1, shewing
my improvements applied thereto.
In the sectional plan, Fig. 1, the part on the left-hand of the transverse centre
line Z Z, represents a furnace with three ports, and the part on the right-hand, a
furnace with five ports.
Similar letters of reference denote similar parts throughout the drawings.
A is the bed of the furnace, B B &c., are the gas and air ports, and C the regenerative
chambers, D is the floor or platform level, E F &c. are slabs of fire clay or other
suitable material, one being placed or built into each gas and air port between the
division walls F on the floor level D, so that they form pockets H to catch the melted
slag and brickwork, which flows down from the port end stopping J, and thus avoid
choking up the ports. These pockets can readily be cleared out at intervals as
required.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. In a "Siemens" regenerative furnace for the manufacture of steel and other
metals, the pockets F in the gas and air ports for the purpose of catching the molten
slagand brickwork and preventing choking of the said ports, substantially as herein
set forth.
2. A "Siemens" regenerative furnace, constructed with pockets F, substantially as
and for the purposes herein shewn and described with reference to the accompanying
drawings.
