HEATING-FURNACE.

SPECIFICATION forming part of Letters Patent No. 241,959, dated May 24, 1881.

Application filed March 7,1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN S. GARD, of Tremont City, in the county of Clarke and State of Ohio, have invented certain new and useful Improvements in Heating Furnaces and Stoves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to heating-furnaces and ventilatin g-stoves, the object ofthe same being to furnish convenient means of access for clearing away the soot and unconsumed products of combustion from between the hot-air chamber and the cylinder G surrounding the same; and it consists in certain details in construction and combinations of parts as will be hereinafter explained, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical section of my furnace or stove. Fig. 2 is a view with the'outer casing removed. Fig; 3 is a vertical section taken through the upper chamber; and Fig. 4 is a transverse vertical section through the line a: w of Fig. 1.

A represents the outer casing, which completely surrounds the internal parts, and is provided with the usual openings for the hotair pipes, smoke-pipe, and doors, and has, in addition thereto, openings on the sides for drawing the air from different parts of the house to be heated, and also capped holes a on the top thereof, for the purpose of cleaning the interior of the furnace or stove.

The ordinary ash-pit, with grate, rests immediately on the perforated bottom b of the outer casing, and is surmounted by a fire-bowl and bell-top, which compose the combustionchamber B, which is provided at its upper end with a perforated transverse annular flange, O, on'which the cylinder 0 rests, thereby forming a smoke-space between the cylinder 0 and the hot-air chamber, through which the smoke passes. The annular flange G is perforated at suitable distances apart for the passage of the cold-air pipes 11 which lead directly from the outer sides of the fire'cliamber or fromthe outer. air to the under side of and into the hotair chamber D.

The fire-box is provided with an opening for the introduction of fuel, which is connected to the outer casing by a neck, D 011 the outer end of which is secured the door I).

The cylinder 0 rests on the transverse annu' lar flange, and is continued upward and completely surrounds the hot-air chamberD, thereby forming an annular smoke-space between the outside of the hot-air chamber D and the inside of the cylinder 0. This cylinder is perforated on top, and has a smoke-pipe, 0, secured therein, and extends up through the hot air space between the outer casing and cylinder 0, and connects with the smoke-pipe which leads to the chimney.

The top or lid ofcylinder O is provided with openings cZhaving flanged shoulders, on which are secured removable caps 0 These openings can be of any desired size or number, and are placed over the annular smoke-space c, and are immediately under the openings at in the outer casing, thereby allowing access from the outside of the outer casing to the smokespace 0 into which can be inserted the brushes or scrapers used for the purpose of freeing the adjacent parts of the soot lodged thereon.

The hot-air chamber D is located inside of the cylinder 0 and over the fire-box, and is held in place by the cold-air pipes, which connect the hot-air chamber, from the bottom thereof, with the air-space surrounding the firebox, and also by the hot and cold air pipes extending from the sides thereof and through the sides of the cylinder 0 and outer casing,respectively. A smoke-flue, a extending throughout the entire length of the hot-air chamber and terminating above in the annular smoke-space c conveys part of the smoke away, while the rest passes around through the annular smokespace 0 and out through the smoke-pipe.

The hot-air chamber D is provided with two or more pipes, at, which pass through the outer casing, A, and intermediate casing, O, and connect with registers or pipes which lead to registers or openings in the floor or ceiling of the rooms above the furnace and draw the air down and mingle it with the cold air received from the pipes in the bottom of the hot-air chamber D. Hot-air pipes (0 connect the hotair chamber at or near its top with the outer hot-air space, from whence the air is taken by the pipes a which open into the top of easing A, and distributed throughout the building.

From the foregoing it will be seen that the cold air entering the furnace or stove from beneath it is heated to a considerable degree by passing up around the tire before entering the hot-air chamber, and alter entering the chamber is still further heated by the direct action of the fire on the bottom of the chamber and from the smoke-space surrounding the same.

The openings on the top of the cylinder 0 and outer casing offer convenient access to the smoke-chamber, and allow brushes or cleaners to beinserted thereinto for removing sooty deposits on the walls thereof. These openings may be provided with removable or hinged caps, as is desired.

I am aware that heating furnaces and stoves have been constructed with a heating-drum inclosed within an outer cylinder and the smoke caused to flow upwardly through a pipe extending through the drum, and the air to be conveyed from the drum through the openings in the outer cylinder, and hence I make no broad claim to such an arrangement of parts.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a heating furnace or stove, the combination, with the outer casing, A, provided with capped openings a, of the intermediate cylinder, G,provided with capped openings 0 and hot-air chamber 1), the openings at and c being arranged to permit of access to the smoke chamber between the hot-air chamber D and intermediate cylinder, 0, substantially as set forth.

2. In a heating-furnace, the combination, with the outer casing, A, provided with heatedair-discharge openings a of the intermediate casing,(), provided with smoke-flue c, hot-air chamber D, central smoke-flue, a, and pipes a a, substantially as set forth.

3. Inaheating-furnace,thecombination,with the outer casiu g, A, provided with dischargeopenings (0",01' the intermediate easing, (J, provided with smoke-flue c and hot-air chamber D, smoke-flue a and pipes a", a, and I)", substantially as set forth.

In testimony that I claim the lbregoing I have hereunto set my hand this 22d day of February, A. I). 1881.
