AIR-TIGHT HEATING-STOVE.
SPECIFICATION forming part of Letters Patent No. 635,566, dated October 24, 1899..
Application filed January 5, 1897. Serial No. 618,037. (No model.)
To aZZ whom, it natty concern:
Be it known that I, WILLIAM M. M LBURN, a citizen of the United States, residing at Harrison, in the county of Boone and State of Arkansas, have invented a certain new, useful, and valuable Improvement in Air-Tight Heating-Stoves, of which the following is a full, clear, and exact description.
This invention relates to air-tight heatingstoves, especially of the wood-burning variety; and it has for its object to efiect certain improvements in stoves of this character whereby a maximum amount of heat may be secured, while at the same time providing a construction in which the exposed portions of the stove-body are better protected from the heat, so as to greatly increase the durability or life of the stove.
To this end the invention primarily contemplates a novel construction of basketgrate that occupies substantially the entire interior area of the stove-body, and which by reason of its construction may be readily removed and replaced, and which provides means for holding the coals or embers not only in an elevated position above the bottom of the stove-body, but also out of contact with the sides.
A further object of the invention is to associatewith the novel form of grate improved means to assist in securing the grate sections or members against lateral or transverse separation and also providing for working the ashes out of the grate and causing the discharge of the latter into the ash-pan.
With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.
In the drawings, Figure 1 is a vertical longitudinal sectional View of an air-tight heatingstove embodying the specific improvements contemplated by the present invention. Fig. 2 is a top plan view of the sectional grate removed from the stove-body and showing the two sections or members of the grate slightly separated. Fig. 3 is a'detail in perspective of the sliding cover-plate for the dump-opening, which carries the transversely-alined series of raking-fingers. Fig. 4 is a vertical transverse sectional view of the stove. Fig. 5 is a front end view of the stove.
Referring to the accompanying drawings, the numeral 1 designates the upright stovebody, preferably constructed of sheet-iron and of the usual elliptical formation. The said stove-body is provided with a flat bottom and also with a flat top portion having the usual smoke-outlet 2 and the enlarged flanged fuel-inlet 3, which is normally closed by a suitable cover 4. These are the usual parts of the body of a wood-burningstove, and in the present invention the said body 1 has the interior Wall thereof provided with a lining of fire-brick 5, which extends from the flat bottom of the stove-body nearly the entire heightthereof to form proper protection for the sheet-metal wall of the body within the plane of the grate, which will be presently referred to.
In addition to the features described the elliptical stove-body 1 is provided at the front end thereof and contiguous to its bottom with an offstanding flared draft-hood 6, which may be fitted directly to the body or to the front door 7, mounted on the body, as shown in Fig. 5 of the drawings. The said offstanding draft-hood 6 is provided at its outer end with a perforated wall, upon whichis revolubly mounted a perforated damper-disk 8, whose openings are adapted to register and disaline with the corresponding openings in the outer end wall of the hood to provide for the proper regulation of the draft as the conditions of the fire may require. The flat bottom of the elliptical stove-body l is provided at a central point therein with a dump-opening 9, having at the side edges thereof the flanged guides 10, which slidablyv receive the side edges of the imperforate cover-plate l1, having at one end a handle-arm extension 19, projecting beyond the front of the stovebody, so as to be within easy reach to provide for sliding the said cover-plate 11 to close or cover the dump-opening 9. In addition to the front handle-arm extension 19 the imperforate sliding cover-plate 11 is further provided near the extreme inner end thereof with a transversely alined series of regularlyspaced and vertically-disposed raking-fingers 11, which fingers cooperate with the grate in a manner hereinafter explained.
From the foregoing it will be seen that the imperforate sliding cover-plate 11 controls the passage of ashes and cinders through the dump-opening 9 and into the detachable ashpan 12. The detachable ash-pan 12 is arranged beneath the bottom of the stove-body and is provided at its upper longitudinal side edges with flanges slidably engaging oppositely-arranged supportingguides 13, proj ected from the bottom of the stove-body, and said ash-pan 10 is preferably provided with a suitable handle at each end, wherebyit may be drawn from beneath the stove-body from either end thereof, as may be plainly seen from Fig. 1 of the drawings.
In the present invention the stove-body is designed to have arranged therein a grate of an approximately semi-oval form and consisting of the duplicate matching sections 14, which bisect the grate longitudinally thereof. The said semi-oval grate is nearly of the same length and width as the stove-body and is dished sufiiciently to form a large basket for the fuel, and each of the grate-sections 14: is provided at its top edge with a semi-elliptical rim portion, having at one end a terminal tongue 16 and at its opposite end the mortise or notch 15 to receive the tongue 16 of the other companion section. The terminal tongues and mortises 16 and 16 of the separate grate-sections 14 are arranged in opposite relation on the sections, so that when the latter are placed together the tongue 16 on one section will fit within the mortise or notch 15 within the other section, thereby securing a firm but readily-separable interlocking connection between the two sections of the grate, so as to positively prevent longitudinal separation thereof after having been placed within the stove-body.
The semi-elliptical rim portions of the gratesections 14 provide for separably interlocking the same in the manner explained, and each of the grate-sections is further provided with a series of curved downwardly-convergent grate-bars and with a plurality of spaced parallel longitudinal bottom grate-bars l8,between which latter bars project the upper end of the raking-fingers 11, carried by the sliding cover-plate 11. By reference to Fig. 4 of the drawings it will be seen that the raking-fingers 11 alternate with the longitudinal gratebars 18 of the grate-sections and by project ing through the spaces between these longitudinal bars provide means not only for relieving the fire from ashes, but also act in the capacity of retaining means for preventing transverse separation of the grate-sections after having been placed within the stove-body.
To provide for the proper support of the grate within the stove-body and in an elevated position above the bottom, each of the grate-sections is provided with pendent supporting-legs 17, extending below the bottom grate-bars and resting directly on the flat bottom of the body continuous with upper horizontal members, forming stops at opposite ends to limit the movement of the raking-fingers at the front and rear and whereby the grate is sustained not only in an elevated position above the stovebottom, but also out of contact with the side and end walls thereof; By reason of thus supporting the grate the draft of air is permitted to freely circulate through the grate not only from the bottom thereof, but also through the curving sidesthus insuring not only a proper draft for the fire, but at the same time preventing the intense heat of the fire within the grate from burning out the contiguous portions of the stove-body.
At one end of the bottom dump-opening 9 the stove-body has fitted to the bottom thereof an upwardly-projecting abutment-plate 20, which not only prevents the raking-fingers 11 from carrying the ashes into the front portion of the stove-body, but also serves to force the ashes between the fingers 11 and over the inner end of the plate 11 into the ash-pan 12. This operation occurs when the coverplate 11 is drawn forward to uncover the dump-opening 9,and at the same time the upper ends of the fingers 11 will rake the fire and liberate the ashes, so that the same may be dumped directly into the bottom ash-pan.
By reason of constructing the grate in the manner herein described it will be understood that the sections thereof may be readily in-' troduced into the stove-body through the fuel-inlet 3 when the stove-body is made without a door at its front end; but of course when the stove is equipped with a door 7 the opening covered by said door may be utilized for placing the grate in position or removing the same.
From the foregoing it is thought that the construction and many advantages of the herein-described improvements will be recognized by those skilled in the art, and it will be understood that changes in the form, proportion, size, and the minor details of construction within the scope of the appended claim may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is-
In a stove, the combination with the body having a fiat bottom provided with a dumpopening, of a sectional two-part basket-grate supported upon the bottom of the body in an elevated position, said grate consisting of too means to hold the sections against transverse :0 separation, substantially as set forth.
In testimony whereof I affix my signature in presence of two Witnesses.
