SMOKE-CONSUIVIING DEVICE FOR STOVES AND FURNACES.

Specification of Letters Patent.

Patented Oct. 10, 1905.

Application filed May 22,1905- Serial No. 261.596.

To alt whom it may concern.-

Be it known that I, DIEGO LANGE, a citizen of the United States, residing at La Crosse, in the county of La Orosse and State of Wisconsin, have invented certain new and useful Improvements in Smoke-Consuming Devices for Stoves and Furnaces, of which the following is a specification.

My invention relates to a smoke-consuming and fuel-saving device for stoves, furnaces, and the like.

The object of the invention is to provide a stove, furnace, or the like with a smoke-consuming chamber within the fire-pot or main combustion-chamber out of the way of the fuel-feed and having flues leading from its ends into the direct draft flue or pipe below a damper therein and also having a third flue leading upwardly from the middle through the stove or furnace into the main flue above the damper. This object I accomplish by the construction shown in the accompanying drawings, in which Figure 1 is a front "sectional view of a stove or furnace with my improvements applied. Fig. 2 is a sectional side elevation thereof, and Fig. 3 is a sectional rear elevation.

A designates the body of a stove or furnace of anysuitable form and construction, and A is the fire-pot, above which is the main combustion-chamber A while below the fire-pot is the ash-pit A The front of the stove is provided with a door a for the introduction of fuel, and a designates the ash-pit door.

B designates the direct smoke flue or pipe provided with a tight damper b.

C designates the smoke and gas consuming chamber, placed horizontally across the firepot and having downdraft flues or pipes O 0 leading from its ends out through the body of the stove and upwardly and inwardly over the top of the stove into the main or direct flue B below its damper b, and D designates a third or updraft flue or pipe leading upwardly from the middle of the chamber (land through the top of the stove into the main or direct flue or pipeB above its damper. These external tubes U C form radiators for heating the room. The chamber C is provided at the rear side of its middle portion with a star-wheel air-intake E, exposed through the rear side of the stove, and this air-intake also permits the chamber to be cleaned out when necessary.

It will be seen from the foregoing that when the damper 6 is open the draft will be directly upward through the main flue B, and this will be the case in starting the fire. \Vhen the damper is closed, however, the products of combustion will pass downwardly through the pipes or flues C G into the highly-heated chamber C, where everything of a combustible nature will be consumed, and the draft will then continue up through the flue or pipe D into the main flue B above the damper b. The air-inlet will be adjusted to allow the proper amount of air to enter chamber C to insure combustion.

The smoke-consuming chamber 0 and the lower end of the flue D are at the rear side of the combustion-chamber, and so directly below the main draft pipe or flue B or in the path of the ascending heat, where they will be heated the hottest. At the same time these parts are out of the way of the introduction of the fuel. That part of pipe D within the stove or furnace is practically a part of the chamber C, as it extends upwardly therefrom in the path of the hottest gases, which burn out any combustible matter that may have passed the chamber U proper. The inclination of flue or pipe D causes any dust or ashes to pass down within reach of the opening E. The improvements are equally applicable to woodstoves.

Having thus described my invention, what Ielaim, and desire to secure by Letters Patent,

1. The combination with a stove or furnace havinga main draft flue or pipe at the rear of its upper portion and provided with a damper, of a smoke-consuming chamber extending upwardly and forwardly from the rear of the main combustion-chamber across the path of the products of combustion and connected at its upper and lower ends above and below the damper for up and down drafts, and an air-inlet and cleaning-out section for the smoke-consuming chamber leading therefrom through rear wall of the stove or furnace and there provided with a valve.

2. The combination with a stove or furnace having a main draft flue provided with a damper, of a smoke-consuming chamber within the fire-space or combustion-chamber, downdraft-flees leading from the main flue, below its damper, exterior to the stove and into the ends of the said chamber, an updraft flue or pipe leading upwardly through the stove or furnace from the middle of the said chamber across the path of the products of I low the damper to said smoke-consuming" chamber, and an updraft-flue leading from said chamber back of the fuel-inlet across the path of the products of combustion, up to the main flue, above its damper.

In testimony whereof I afiix my signature in presence of two Witnesses.
