Specification of Letters Patent.

Patented May 25, 1915.

Application filed January 16, 1915. Serial No. 2,663.

To all whom it may concern Be it known that 1, Banner H. CAs'rLE, a citizen of the United States, residing at Quincy, in the county of Adams and State of Illinois, have invented new and useful Improvements in Heating-Stoves, of which the following is a specification.

My present invention pertains to heating stoves; and it contemplates the provision of a heating stove constructed with a View to assuring perfect combustion of fuel, the utilization of practically all of the heat value of the fuel, and the maintenance of a large body of air in close contact with the heat to promote the thorough heating of the air in an apartment.

With the foregoing in mind the invention will be fully understood from the following description and claims when the same are read in connection with the drawing, accompanying and forming part of this specification, in which the figure is a perspective view, partly in section and partly broken away, of a heating stove constructed in accordance with my invention.

My novel stove is provided with the usual ash pit 1, fire pot 2, and cylindrical body portion 3, superimposed on the firepot and provided with the conventional or any other suitable openings 4 and 5. At the upper en d of the fire pot- I prefer to employ a hollow annulus 6, communicating with the damper 5 and having a plurality of apertures 6 designed to supply fresh air to the fire in the pot 2 with a view to promoting the combustion of the fuel. This annulus, however, is not of the essence of my invention and it may therefore be omitted without involving departure from my claimed invention.

At 8 the stove body is provided with an outlet for smoke and other products of combustion, and it is also equipped with an interior hollow baffle or deflector 9. This hollow bafi'le or deflector fits tightly against the inner side of the body at opposite points, and is suitably connected to the body at the points 10 or at any other points compatible with the purpose of my invention. From a point below the outlet 8 to a suitable distance from the top of the body the hollow baffle or deflector is arranged in spaced relation to the wall of the body, this in order to afford a down flue 11 which constitutes an important part of my invention. Below the outlet 8 the battle or deflector 9 fits tight against the wall of the body around an opening 12 in said wall and through this opening the hollow baffle or deflector is connected with an exterior cold-air conduit 13. This conduit 13 extends downwardly to a point at the underside of the ash pit 1 and is there preferably, though not necessarily, provided with a contracted mouth 1%, designed to receive air from a point adjacent to the floor of the apartment. At its upper end the hollow baffle or deflector 9 merges into or is connected with an upwardly extending conduit 15 which extends through the top of 1the stove body and is open at its upper enc.

In the practical use of my novel stove, it will be manifest that in passing from the fire pot 2 to the outlet 8, the smoke, hot air and other products of combustion must first pass upwardly at one side of the hollow baflie or deflector, and then downwardly at the outer side of the upper portion of said baffle or deflector. From this it follows that the products of combustion are retained and circulated in the stove body with the result that the amount of heat radiated from the body is materially increased. It also follows that the conduct of the products of combustion first upwardly and then downwardly in immediate contact with the upper portion of the baffle or deflector as well as around and in immediate contact with the conduit 15 assures the thorough heating of the air that is carried upwardly through the conduit 13, the hollow baffle or deflector and the conduit 15, with the result that the efficiency of the stove is materially increased. It will further be noted that when combined with the hollow foraminous annulus or gas ring 6, the hollow baffle or deflector 9 assures perfeet combustion of all of the fuel before the same leaves the stove body, and consequently all of the heat value of the fuel is radiated from the stove body or else is utilized to heat the air that is conducted from the lower portion of the apartment through the baffle or deflector and back to the upper portion of the apartment.

Having described my invention, what I claim and desire to secure by Letters-Patcut, is:

1. In a stove, the combination of a body having an outlet for products of combustion at an intermediate point in its height and also having an opening located below said outlet, an exterior cold-air conduit connected with said opening and extending downwardly therefrom and open at its lower end,

a hollow baflle or deflector arranged in the body and having its vertical sides fitting tightly against and connected to the inner side of the body at opposite points and also having its lower portion fitted tight against the inner side of the body around the said opening thereof, and further having its upper portion spaced from the inner side of the body from a point below said outlet of the body to the upper end of the baflle or deflector; the interior of said baffle ordeflector being entirely isolated from the interior of the body, and a conduit communicatingwith the interior of the baflie or deflector and extending through the top of the body and open at its upper end.

2. In a stove, the combination of a body having an outlet for products of combustion at an intermediate point in its height and also having a cold-air inlet arranged below said outlet, a hollow baffle or deflector fixed in the body and communicating with said cold-air inlet and having its interior entirely isolated from the interior of the body and also having its upper portion arranged relatively to the wall of the body to form a down-flue that is closed at its sides and lower end and open at its upper end and leads to the outlet for products of combustion, and a conduit leading from the interior of the baffle or deflector through the wall of the body and open at its outer end.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
