I 0 aZZ whom it may concern.-

Be it known'that we, JOHN A. TOPLIFF, EDWARD S. ORoss, WILLIAM S. COX, and JOHN A. MOOOLLUM, citizens of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented a new and useful Improvement in Furnaces, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

Our invention relates to furnaces for heating public buildings, dwelling-houses, 8m, with hot air; and it consists of a furnace specially adapted for burning soft or bituminous coal in such manner as to secure a thorough consumption of the gases and smoke that are rapidly given Off by such coal, all as hereinafter described and claimed.

In the drawings, Figure 1 is a central ver tical section of ourimprovedfurnace, and Fig. 2 is a section on line 00 w of Fig. 1.

The furnace embraces a fuel-chamber, A, a combustion-chamber, B, located on the same level with chamber A, and aheatingdrum, O, locatedabove chambers A B and communieating with chamber B. The fuel'chamber is lined with fire-brick a and has a grate, D. D is a horizontal grate on alevel with draftdoor E and the flue F.

G is the ash-pit, through which air is supplied to the fuel from under the grate, as indicated by the arrows, and H isthe door opening into the fuel-chamber. The flue F at the rear end of the grate D consists of a flanged lining, i, which is bolted to the wall of chamber A and B. Within this flanged lining are built a series of fiues, four or more, according to the size of the furnace, out of fire-brick. Said Hues-are about one and a half or two inches in width, from eight to twelve inches in height, and from six to ten inches in depth. The Object of ,flue F is, first, to retain the coal in its place, and, second, to assist very materially in the combustion of smoke and gases when they (the flues) become thoroughly heated.

- ber B.

L indicates a flue leading from chamber A to chamber B above the fuel, and L is a valve located in said flue. When the door H is opened to supply fuel to chamber A,the valve L is first to be opened to prevent a backward draft through the door. The drum 0 is supported on the walls of the chambers A B, and communicates with chamber B by a flue, N. The drum I is provided also with a diaphragm, O, and it communicates with the pipe P,leading to a chimney. (Not shown.)

Q. indicates an air-space in which the airis heated, and R indicates pipes for conducting hot air to the rooms which are to be heated.

What we claim is A heating-furnace consisting, essentially, of the vertical fuel-chamber A, having the feeddoor H, the draft-door E, the horizontal grate D, in line with the draft-door, an ash-pit, the vertical combustion chamber B, the flanged. lining 2', connecting said chambers in line with the grate, the vertical fire-bricks therein, the flue L, valve L, the air-supply pipes J in the lower end of the combustion-chamber, the exit N, the horizontal drum or radiator O, and the outer surrounding casing, substantially as herein set forth.
