proved burner and heater.*

Claims.—(1.) In the improved burner and heater specified,
in combination, the tube having its lower end shaped with a
lip projection with the pipe coiled around said tube and ends
of said tube shaped one to fit into any suitable form of reser-
voir and the other end to fit into a chamber, said chamber
bored to allow the oil or feed to pass from the reservoir
through the coiled pipe when ends are fitted to the small hole
provided in top of said chamber, with nipple fitted into under-
part of said chamber, gland screwed on to said nipple and
suitably packed, and rod with disc or wheel on its lower end
screwed into inner part of said chamber so that the fine or
needle point of said rod can be made to project into and
through said small hole or be withdrawn therefrom, all for
the purposes set forth, substantially as described and illus-
trated. (2.) In the improved burner and heater specified,
the tube having its lower end shaped with a lip projection
and fitted centrally to the pipe coiled around said tube, said
coiled pipe having its ends connected respectively to a reser-
voir and the chamber, for the purpose set forth, substantially
as described and illustrated. (3.) In the improved burner
and heater specified, the pipe coiled around the tube and
having its ends connected respectively to a reservoir and the
chamber, for the purpose set forth, substantially as described
and illustrated. (4.) In the improved burner and heater
specified, the chamber bored for the coiled pipe to fit therein
on its upper side and bored for the nipple to fit therein on its
under-side, with a bore made at right angles to and connect-
ing said two bores, and with said nipple-bore prolonged to a
small outlet-hole on the upper side of chamber, the nipple
screwed into said bore, the gland centrally packed with as-
bestos or other suitable packing screwed on to said nipple,
the rod having its upper end shaped with a needle or fine
point and its lower end mounted with a wheel or disc, said
rod screw-threaded to engage and work in reciprocal screw-
thread made within said prolonged nipple-bore and to pass
through said packed gland and nipple so as to engage and
close small outlet-hole or to disengage therefrom so as to
leave it the small outlet-hole open, for the purpose set
forth, substantially as described and illustrated. (5.) The
general construction, arrangement, and combination of the
different parts specified, for the purpose set forth, substan-
tially as described and illustrated.

No. 16963.—9th September, 1903.—MONTAGUE MOORE, of
408, Collins Street, Melbourne, Victoria, Mining Agent, and
THOMAS JAMES HESKETT, of 86, Donald Street, Bruns-
wick, Victoria, Engineer. Improvements in the treatment
of ore for the manufacture of iron and steel.*

Claims.—(1.) Our improved process of treating ferruginous
ore for the manufacture of iron and steel therefrom, consist-
ing in concentrating and separating such ore, subjecting it to
the action of heat and then to the reducing action of carbonic-
oxide or hydrocarbon gas, and finally passing it without com-
ing in contact with an oxidizing atmosphere into a Siemens
or other gas-furnace, where it is fused and “balled up” as
wrought iron or converted into steel, substantially as
described and explained. (2.) Our improved process of
treating ferruginous ore for the manufacture of iron and steel
therefrom, consisting in concentrating and separating such
ore, subjecting it whilst passing through a chamber to the
action of heat produced by the combustion of waste carbonic-
oxide or hydrocarbon gas issuing from another chamber with
air, and subsequently to the progressive reducing action of
such gas or gases alone whilst passing through said latter
chamber, and finally passing it without coming into contact
with an oxidizing atmosphere into a Siemens or other gas-
furnace, where it is fused and “balled up” as wrought iron
or converted into steel, substantially as described and ex-
plained. (3.) In a process of treating ferruginous ore for the
manufacture of iron and steel, in which the ore after being
heated in one chamber is subjected to the action of hydro-
carbon gas in another chamber, conveying a portion of such
gas from the upper portion of such chamber to a Siemens
or other gas-furnace for the purpose of heating it, substan-
tially as described and explained. (4.) The combination
with a tower A, the upper portion of *which constitutes a
heating-chamber A¹ and the lower a deoxidizing-chamber A²,
of a Siemens or other gas-furnace H and an inclined passage
D connecting the base of such tower with the top of said
furnace, substantially as described and explained, and as
illustrated in Fig. 1 of the drawings. (5.) The combination
with the deoxidizing-chamber A² of air-inlets D³, means for
regulating the supply of air thereto, pipe E, and valve F, sub-
stantially as described and explained, and as illustrated in
Figs. 1 and 4 of the drawings. (6.) The combination with
the passage G, leading to an opening in the top of the gas-
furnace H, of valve I, gaspipe J, and firebrick valve K, sub-
stantially as described and explained, and as illustrated in
Figs. 1 and 4 of the drawings. (7.) The combination with a
vertical deoxidizing-chamber A², passage G, and Siemens fur-
nace H, of a revolving cylindrical heating-chamber A¹ set at
an angle thereto, substantially as described and explained,
and as illustrated in Fig. 4 of the drawings. (8.) The com-
bination of a gas-furnace H, a revolving cylindrical heating-
chamber A¹, a revolving cylindrical deoxidizing-chamber A²,
each chamber being set at an angle, and a vertical chamber R
connecting the lower end of the former chamber with the
upper end of the latter chamber, said vertical chamber R
being provided with air-inlets D³, and said chamber A² with
means such as J for supplying gas thereto, substantially as de-
scribed and explained, and as illustrated in Fig. 7 of the
drawings. (9.) The combination with the deoxidizing-cham-
ber A² of the means for controlling the supply of ore to such
chamber and for withdrawing the surplus gas therefrom,
substantially as described and explained, and as illustrated in
Fig. 7 of the drawings.
