I, JAMES RILEY, General Manager to The Steel Company of Scotland, Limited,
of 150 Hope Street, Glasgow, in the County of Lanark, North Britain, Engineer,
do hereby declare the nature of my said invention for "IMPROVEMENTS IN THE
MANUFACTURE OF STEEL IN REGENERATIVE OPEN-HEARTH FURNACES,'
to be as
follows, that is to say :-
"
:
My said Invention has for its object to improve the manufacture of steel in
regenerative open-hearth furnaces; and it consists in cansing the air or the gas or
both the air and the gas to be projected into the reverberatory chamber with more
force than that ordinarily due to the draught, in order that the ignited gases may
act more energetically and expeditiouly on the materials in the furnace.
In carrying out my Invention instead of admitting the air into the valves and
passages under merely atmospheric pressure, I connect the valve casing to suitable
blowing or air forcing apparatus by which the air is made to enter the passages
with the desired pressure. And in a similar way I lead the combustible gas
through suitable blowing or forcing apparatus, so that it may have the desired
pressure when passing. through the passages and the regenerative chamber on its
way to the furnace or reverberatory chamber. The pressures of the air and gas
may be separately regulated and adjusted as may be found desirable in practice.

I JAMES RILEY General Manager to the Steel Company of Scotland Limited of
Glasgow in the County, of Lanark, North Britain, do hereby declare the nature of
my invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My said invention has for its object to improve the manufacture of steel in
regenerative open hearth furnaces; and it consists in causing the air or the gas or
both the air and the gas, to be projected into the reverberatory chamber with more
force than that ordinarily due to the draught, in order that the ignited gases may
act more energetically and expeditiously on the materials in the furnace.
In carrying out my invention instead of admitting the air into the valves
and passages under merely atmospheric pressure I connect the valve casing to
suitable blowing or air forcing apparatus by which the air is made to enter the
passages with the desired pressure above that of the atmosphere. And in a similar
way I lead the combustible gas through suitable blowing or forcing apparatus say
a Rook blower so that it may have the desired pressure when passing through the
passages and the regenerative chamber on its way to the furnace or reveratory
chamber. The pressures of the air and gas may be separately regulated and
adjusted as may be found desirable in practice.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed I declare that what
I claim is:
First. The improvements in the manufacture of steel in regenerative open hearth
furnaces substantially as herein setforth.
Second. In the manufacture of steel in open hearth regenerative furnaces causing
air or gas to enter the furnaces at a pressure above that of the atmosphere for the
purpose setforth.
Third. In the manufacture of steel in open hearth regenerative furnaces causing
air and gas to enter the furnace at a pressure above that of the atmosphere for the
purpose setforth.
