SPECIFICATION forming part of Letters Applicatifn filed March To all whom it muy concern:
Be it known that I, CHARLES W. BLISS, ot' Wilmington, Delaware, have invented certain new and useful Improvements in Smelting- Furnaces; and I do hereby declare the following to be a full, clear, and exact. description of the same, reference being had to the annexed drawings, forming part hereof.
The nature of my invention will fully ap- [o pear from the following specication and claims.
In the drawings, Figure l is a vertical sectional view of my furnace on line z z ot' Fig. 3, showing the stennrboiler in the interior,
on linery y ot' Fig. 3; Fig. 3. a horizontal seetional View on theline x m of Fig. l; Fig. 4, a detached view ot'one of my tire-bricks, showin g a grooved or recessed back.
A is the top or root' of the furnace; A', the sides or walls thereof.
B B B are my tire-bricks, slightly converg- 'ing below toward the foot of my lire-brick grate-cone U G. These tire-bricks B B have spaces B B between them, and an annular space, B", between theirlower parts and the wall A.
B." B are projections to sustain the firebricks in place. The grate-bars C C have 3o spaces D D between them, and inclose a hol,
low conical Space below.
E is a tine or recess in the back of bricks B, communicating below with the annular space B" and openings K, and above with the open space inclosed by the cover or top A.
G is a feed opening or door; H, a steamboiler; H', a steam -conduit leading to an opening below to inject steam into the charge.
I is the foundation of the cone and iire- 4o brick chamber, also forming a metal chamber.
F is an opening from the inner space of the cone to remove the charge; J, an opening to remove the slag.
K are draft-holes.
The operation of my furnace is as follows: The fuel and charge are inserted through the door G, and are ignited below through door F. They lie upon and around the cone C. The charge is not piled in so as to lie above 5o the holes K, as it would Stop them up. The
hollow cone grate will thus be seen to project well up through the mass of the charge.
Patent No. 255,759, dated April 4, 1882. 30,1881. (No model.)
Draft is supplied through draft-holes O, as many of which may be used as are found necessary. Draft is thus maintained from every direction through slits B to the mass, and most perfect combustion and thorough 'and almost simultaneous' melting of the Whole charge is secured. The annular space B" may be used as a hot or cold air chamber, as jets 6o ot' either hot or cold air may be introduced thereto through the walls A at one or more points. Thesteam-boilerHisheated bytheheat of the furnace, or the steam may be carried from a boiler outsidethereot', or the boilerrmay be set 65 in one side of the walls of the furnace to be heated therefrom. The openings L M are for the combined oil and steam jets-L for the steam andM for the oil. The steam and oil unite after passing through these openings, and are then projected by the steam-pressure through one ot' the slits B', and then pass down through a slit, D, to the cone-chamber, beneath which oil burns with a tierce flame, and assists in the reduction of the mass.
The openings F and J are closed by means of clay during the reduction of the mass. Other shaped openings than those shown at D and B might be used, but I prefer those shown; andthe cone U might be altered in 8o shape, but I prefer this shape, as it is best calculated to sustain the weight of ore and carry the ame from beneath into the interior of the mass of ore. The molten metal passes from the chamber beneath the cone out through the orilice F when the furnace is empty.
What I claim as new is- 1. In combination with the exterior walls of the furnace, an interior brick lining, B, set away from the outer wall, whereby an aunu- 9o lar chamber, B, is left between the lining B and said exterior wall, and openings Bf extending from the bottom to near the top of the lining B, substantially as described.
2. In combination with the exterior walls of the furnace, an interior brick lining provided with graduallydecreasing openings extending from the bottom to near the top, substantially as specified. f
CHARLES BLISS.
