I GAS-BELL FOR FURNACES."

SPECIFICATION forming part of Letters Patent No. 735,421, dated August 4, 1903. Application filed January-27, 1903. Serial No. 140.687. (No model.)

To all whom, it may concern: I

Be it known that I, EMIL R. STASGH, a cit i zen of theUnited States, residipg at Corning,

in the county of Steuben, State of New York, have invented certain new and-useful Improvements in Gas-Bells for Furnaces, of which the following is a specification, reference being bad therein to the accompanying drawings.

Thisinvention relates to a gas-bell for furj naces, and particularly toa construction of parts adapted to be suspended in the center of the fire-box to occupy a portion of thecoalspace and to burn the gases from the center of a body of coal.

Theinvention has for an object to provide a mixing chamber suspended abovethe grate having openings adapted to permit the en= trance therein of the gases from the body of the coal, wherethey will be mixed with air and burned at'the upper portion of the chamber.

A further object of the invention is to com-.

bine with this chamber a Water-heating re ceptacle, so that the ignited gases,in connection withthe furnace-fire, assist in heating the water.

Other and further objects andadvantages:

of the invention will be hereinafter set forth and the novel features thereof defined by the any form of furnace, but for the purpose of illustration is herein-shown in connection with a hot-airfurnace of substantially the construction shown in my prior patent, No. 489,994, dated January 17, I893.-

The letter A designates a fire-box having the grate-bars A at the lower portion thereof and the ash-'pitA beneaththe bars. Above the fire-box a dome A is provided, and circumferentially thereto hot-air flues A extend through the dome to be heated by the products of combustion. A suitable ash-door A is provided to the ash-pit'and a feeding-door A at the dome portion, while extending from the dome is a smoke-flue A communicating with a smoke-pipe A said line being provided with a damper A, by which the products of combustion may be directed downward into the radiating-chamber A from which they may escape by a flue A into the smoke-pipe A This flue is also provided with a check-draft dam per A, while the furnace itself is suitably inclosed within a hotso as to effect a compression of the fuel within the chamber and form a jet adaptedto be ignited at that point. As shown in Fig. 1, this chamber occupies the center of the fuelspace and is suspended above the grate-bars, so as to permit a free operation of the same and also to receive air between the bars from the ash-pit. The fuel extends around the lower portion of the chamber and the openings O therein, so that the gas generated in the center of the body of the fuel by the heat is admitted into the chamber and there mixed with the air from the bottom of the chamber, from whence the mixed fluids escape through the openings 0 where, they are ignited and burn above the body of the fuel,thi s tending to heat the dome containing the hot-air fines to a' greater extent than by the fuel alone. If so desired, a water-receptacle D may be provided above the top of the mixing-chamber and has communicating therewith an inletpipe D and an outlet D extendingdownward from the dome A to which they are affixed for the purpose of suspending the bell above the grate-bars. These pipes may extend to any desired point Where thewater is to be used, and the location of the receptacle directly above the burner-openings 0 causes the receptacle to be heated by the gas-flame from these openings and provide a rapid and desirable method of heating water by utilizing the gasesfrom the fuel.

The operation of the invention will be apparent from the foregoing description, and it will be seen that the suspension of the gaschamber above the grate-bars in the center of the fire-box economizes in the amount of fuel required, the center of the body of which is frequently of very little use for heating purposes, particularly where it is desired to heat the exterior Walls of the fire-box to the greatest extent. Furthermore, this chamber relieves the fuel of the liberated gases which are therein mixed with air and burned to increase the heating capacity of the furnace and also to prevent the escape thereof into the hot-air flues, which occurs if any loose joint-s exist. Furthermore, the arrangement of the water-receptacle relative to the burneropenings provides for the heating of water within the furnace when desired, and these openings carry a heating-flame upward above the main body of the fuel, which materially increases the temperature of the dome proportionate to the amount of fuel used.

It will be obvious that changes may be made in the details of construction and configuration of the several parts hereinbefore described and that the invention may be applied to any desired form of furnace without departing from the spirit thereof as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to .secure by Letters Patent, is-

portion and with burner openings at the upper portion of the chamber within the fire-box. 2. In a furnace and in combination with the grate thereof, a mixing-chamber comprising a cylindrical body having an open lower end supported adjacent to the grate and provided with elongated inlet-openings at its lower portion and tapered burner-openings at the upper portion thereof.

3. In a device of the class described, a furnace, a mixing-chamber supported above the grate thereof and provided with gas inlet openings at its lower portion and burneropenings at the upper portion thereof, a water-receptacle disposed at the upper portion of the mixing-chamber above said burneropenings, and inlet and discharge pipes for said receptacle.

4. In a device of the class described, afurnace, a mixing-chamber supported above the grate thereof and provided with gas-inlet openings at its lower portion and burneropenings at the upper portion thereof, a water-receptacle disposed at the upper portion of the mixing-chamber above said burneropenings, and inlet and discharge pipes for said receptacle said pipes being secured to the dome of the furnace to suspend the mixing-chamber therein.

5. A gas-bell comprising a cylindrical body having a mixing-chamber open at its lower end and provided with inlet and outlet openings in the Wall thereof, and a Water-receptacle disposed within the upper portion of said body above said outlet-openings.

In testimony whereof I affix my signature in presence of two witnesses.

EMIL R. STASGH.
