STOVE.

Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed February 21, 1906. Serial No. 802,237.

To all whom it may concern:

Be'it known that I, MELVIN DECKER, a citizen of the United States, residing at Vicksburg, in the county of Kalamazoo and State of Michigan, have invented new and useful Improvements in Stoves, of which the following is a specification.

My invention relates to stoves, and more particularly a construction to permit the use of bituminous fuel without smoke and waste.

To this end the invention consists in an arrangement of parts whereby the products of combustion are caused to draw down or pass through the burning fuel before escaping through the exit-flue, so that all soot and other heavy matter is thoroughly burned out and thick smoke and soot avoided.

In the accompanying drawings, Figure 1 is a vertical section through the stove and my attachment. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1.

Referring specifically to the drawings, 5 denotes the body of an ordinary cylindrical stove, having a base 6, which is supported on suitable legs 7. The grate is indicated at 8 and the ash-pit at 9, the latter having a door 10 for removal of the ashes, &c. The exitflue is indicated at 1 1.

Within the stove above the grate is arranged a fuel-feeding drum or magazine 12, extending downwardly from the top of the stove. The top of the magazine is open to permit the introduction of the fuel through an opening 13 in the top of the stove. A lid 14 or other suitable closure for the magazine is provided. The bottom of the magazine is spaced from the grate and fits closely against the back of the stove, as at 15, for a purpose to be stated. The magazine is preferably made conical, the smaller end being at the top, so that the fuel will not clog therein and will feed freely.

At 16 is indicated an air-feeding pipe which extends downwardly from the top of the stove and enters the magazine near the lower end thereof, as at 17. The outer end of the pipe 16 can be provided with a damper 18 to control the supply of air to the magazine. Above the entrance of the pipe 16 into the magazine the latter is surrounded by a jacket 19. The lower end of the jacket is left open, but its top end is closed by extending it inwardly against the magazine. The

jacket forms a dead-air space around the magazine above the air-inlet 17, which is for a purpose to be hereinafter described.

When the stove is in use, combustion of the fuel takes place within the magazine 12 as far up as the entrance of the ipe 16, so that the draft passes downward y through the mass of incandescent fuel on the grate and in the magazine below the entrance of the pipe 16 before escaping out of the exit-flue. This causes all soot and heavy matter to be entirely burned out and makes the stove practically smokeless as well as economical. The amount of air fed to the magazine is regulated by the damper 18. The jacket 19 me vents the flames from striking the magazine, which, together with the dead-air space heretofore referred to, protects the magazine from becoming excessively heated above the entrance of the air-supply pipe, whereby combustion in the magazine above said entrance is prevented. By fitting the bottom of the magazine closely against the back of the stove the smoke and gases are prevented from escaping directly from the back of the magazine, but are forced out into the front of the stove. The heat is thus evenly distributed throughout the stove and the heating capacity thereof increased. The products of combustion pass down through the burning mass of fuel and out under the front side of the magazine and thence up the front of the stove and around the jacket to the fiue 11. The air-feeding pipe 16 is in the path of the hot products of combustion, which heats the air before it is supplied to the fuel. This materially assists combustion.

The parts herein described can be readily fitted to any ordinary cylindrical stove and permit the use of any grade of bituminous coal, from slack to domestic.

I claim In a stove, in combination, a magazine in the body thereof, and fitting at its lower end against the back of the stove; an exit-flue at the back of the stove adjacent the top of the magazine, whereby the products of combustion are forced to rise at the front part of the stove and to pass around the upper portion of the-magazine to the exit-flue; an air-feeding pipe which extends downwardly from the top of the stove between the magazine and the front of the stove through the path of the products of combustion, and entering the name to this specification in the presence of magazine near the lower end thereof, Wheretwo subscribing Witnesses. by the air is heated before bein delivered to the magazine; and a jacket arou nd the maga- MELVIN DECKER 5 zine above the entrance of the aforesaid air- Witnesses:

feeding pipe. J ENNIE GARDINER, In testimony whereof I have signed my TYRRELL RAYNER.
