Q 27 I k IV/T/YISJEJ UNITED STATES PA COAL-STOVE.
Specification forming part of Letters Patent No. 22,643, dated January 18, 1859; Antedated November 24, 1858.
To all whom it may concern:
Be it known that I, RENSSELAER D. GRANGER, of the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Coal-Stoves; and I do hereby declare the.
combusion of gases, a great portion of which,
even in professed gas-consuming stoves, passes off unconsumed to the chimney. This end is accomplished by jets of air, passing directly onto the fire through the perforations of the above mentioned chamber, which can be temporarily moved from its postion, on the introduction of the requisite supplies of fuel, or when the fire is so thoroughly ignited as to present no gases for combustion. 1'
In order to enable others to make and use my invention, I will now proceed to describe its construction and operation.
On reference to the accompanying drawing, which forms a part of this specification: Figure 1, is a sectional view of my improved gas-consuming coal stove. Fig. 2, a sectional plan on the line 1, 2, (Fig. 1) of the stove inverted. Fig. 3, an inverted plan, showing a modification of my invention.
A is the body or casing of the stove, B the cover of the same, C the ash pit, D the firepot, E the grate, F the fire door, and G the pipe to the chimney.
II is a chamber of less diameter than the interior of the stove, and from each side of this chamber projects a hollow trunnion a, each trunnion passing through the side of the casing and communicating with an air passage J, which terminates a short distance from the top of the ash boX, and there communicates with the interior air. The latter, passing upward, has no exit but through the perforations on the under side of the chamber H, which is situated as near to the fire as possible.
The fuel being ignited, heat is instantly imparted to the chamber H and its hollow trunnions a, as well as to the passages J J, up which the air rushes, and is ejected, in a heated state, through the perforations at the bottom of the chamber, onto the products of combustion, the unconsumed gases of which are ignited by being brought into contact with the jets of heated air, and pass up in the form of a flame to the chimney.
Heated air has heretofore been brought into contact with the products of combustion in stoves, but, for the most part, at such disadvantageous points, that the effect desired has never been thoroughly attained. By placing the chamber I-I central with the firepot and as near to the fuel as possible, the products of combustion are dispersed, directed from the center of the stove, and thereby thoroughly exposed to the jets of heated air from the perforations of the chamber. Moreover, in other contrivances having the same objects in view, the arrangements for heating the air have been so situated that no gas-consuming effect can take place until the fuel has been ignited for a length of time, during which, those gases which are generated from new supplies of fuel, have passed off unconsumed to the chimney.
As the chamber H becomes heated the moment the fire is lighted, the above defect must be obviated. It will be observed, that one of the hollow trunnions is furnished on the outside with a handle 2', by means of which the chamber may be partially turned, thus allowing the requisite supplies of fuel to be passed through the door F.
In the modified improvement illustrated in Fig. 3, the trunnions a are placed at the back edge of the chamber, so that, when the latter is raised, more room is presented for the introduction of the fuel, than when the trunnions are central with the chamber.
IVhen the fire has burned to a bright red heat, the jets of heated air become unnecessary, as no further gases are presented for ignition. The chamber may, therefore, be turned up, so as to remove it as far as possible from the injurious action of the fire. hen this has been done, the air heated in the chamber, passes through the perforations into the upper portion of the stove, thus adding to the heat of the latter.
It is evident that the form of the perforated chamber may be modified and that different means of changing its position may be adopted, without claiming the precise form of chamber illustrated therefor or the precise mode of hanging it to the interior of the stove.
I claim and desire to secure by Letters Patent Hanging within the stove and immediately above the fire a perforated chamber H,
