STOVE.

SPECIFICATION forming part Of Letters Patent N0. 628,272, dated July 4, 1899 Application filed January 24, 1898. Serial No. 667,782. (No model.)

To aZZ whom, it 11110.3 concern.-

Be it known that 1, JOHN P. LYNOTT, of the city of Louisiana, Pike county, State of Hissouri, have invented certain new and useful Improvements in Stoves, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates generally to stoves, and more particularly to a heating stove of the downdraft variety; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, and claimed.

Figure 1 is a rear elevation of a stove constructed in accordance with my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical sectional view taken approximately on the line 3 3 of Fig. 1. Fig. 4 is an enlarged vertical sectional view taken approximately on the line 4 4 of Fig. 2. Fig. 5 is a view in perspective of a specially-formed box of which I make use in my improved stove and which Iterm the draft and damper box. Fig. 6 is a plan view of the body portion of the stove, showing the f u el-inlet and the draft-openings.

Referring by numerals to the accompanying drawings, 1 indicates the base of my improved stove, which is oval in plan View, and said base is provided with the cast bottom plate 2 and cast top plate 3. The body or drum 4 of my improved stove extends upwardly from the top side of the front portion of the top plate 3, said body or drum being provided with a suitable top plate 5, in the center of which is a fuel-inlet 6, closed by the pivoted plate 7, and in said top plate 5 is also formed a series of draft-openings S, which are adapted to be shut or closed by the sliding damper 9. Located in the lower end of the body 4 is the grate 10, and immediately above said grate is the fire-box 11. Formed in the body 4 of the stove at a point slightly below the upper end of the fire-box 11 is a continuous row of draft-apertures 11. Formed in the top plate 3 immediately behind the body 4 is an oval opening 12, which is bounded by the upwardly-projecting flange 13. Formed in the bottom plate 2 below the opening 12 is a pair of air-inlets 14, the same being bounded by the upwardly-extending flanges 15,formed integral with the bottom plate 2.

16 indicates a rectangular sheet-metal draft and damper box, the edge of the open rear end being provided with the integral flange '17, through which flange passes the rivets or screws, whereby said draft and damper box is securely fixed to the rear side of the upper end of the body 4, there being a rectangular opening 18, formed in the upper end of said body 4, that coincides with the open rear end of said box 16. Formed in the bottom of this box 16 is a rectangular opening 19. Formed integral with and projecting laterally from the lower edges of the sides of the box 16 are flanges 20, and formed integral with and projecting downwardly from the under side of this flange 20 and from the under side of the box 16 is an oval flange 21, which is identical in size and form with the upwardly-projecting flange 13. The lower end of the oval sheet-metal cylinder 22 is located upon the upwardly-projecting flange 13, while the upper end of said cylinder 22 is located upon thedownwardly-projectingflange21. Formed through the flanges 20, inside the space bounded by the ends of the flange 21, are openings 23, the under side of their edges being bounded by the downwardly-projecting flanges 24.

Suitable sheet-metal tubes 25 have their lower ends located upon the upwardly-projecting flanges 15 of the bottom plate 2, and the upper ends of these tubes 25 are located upon the flanges 24.

26 indicates a damper which is pivoted transversely in the bottom of the box 16 at a point immediately in front of the opening 19 in the bottom of said box, and when said damper is turned upwardly it will close the opening 18. hen said damper 26 is turned downwardly, it will close the opening 19 in the bottom of the draft-box 16.

111 the operation of my improved stove when the fire is first kindled therein the damper 26 is turned downwardly, so as to close the opening 19. The smoke, flame, and products of combustion from the fire will now pass upwardly through the upper end of the body 4 of the 'stove, out through the opening 18, through the draft box 16, and upwardly through the pipe that leads from the top of said draft-box to the flue; When the newlykindled fire is well started and it is desired to manipulate said stove so as to heat the air in which said stove is located, the damper26 is turned upwardly, so as to allow free passage from the opening 19, and this movement of the damper closes the opening 18. The damper 9 in the top of the stove is now manipulated, so as to allow the required amount of draft to pass through the draft-openings 8, and said draft will pass downwardly through the fire, as indicated by the arrows, from thence through the grate 10 into the oval body 1, from thence upwardly through the oval cylinder 22, through the opening 19 in the bottom of the draft-box, through said draft-box, and from thence out through the length of pipe to the flue. This draft is greatly assisted by the draft that enters the apertures 11 in the body of the stove 4 and mingles with the first-mentioneddraft immediately beneath the grate 10. As fresh fuel is passed to the interior of the body of the stove through the fuel-opening 6 it will be consumed by the fire within the fire-box 11 and the smoke, gases, and other products of combustion will pass downwardly through the fire and bed of coals which has been formed upon the grate 10, and said smoke and other products of combustion will thereby be consumed and only the White smoke or certain unconsumable gases, together with the heat from the fire, will pass upwardly through the oval cylinder 22 and draft-box 16. As said heat passes upwardly'through the oval cylinder22 the tubes 25 within said cylinder will become very thoroughly heated, and therefore the air which is taken from beneath the stove and which passes upwardly through said tubes 25 will become very thoroughly heated and will be passed out through the openings 23 in the flanges 20 in said heated condition.

The draft to the fire within the fire-box 11 is regulated by manipulating the damper 9 and by also manipulating the damper 26, it

only being necessary to turn said damper 2G downwardly to close the opening from the damper-box to the oval cylinder 22, and thus the oval cylinder 22 ceases to be a heatingdrum.

Thus it will be seen how I have constructed a very eflicient heating-stove, one which is simple in construction and requires but very little attention and which stove very readily and completely consumes the products of combustion arising from the newly-fed fuel.

I claim- In a stove of the class described, the com bination with the oval base 1, the cylindrical body t mounted upon said base, in the upper' end of the rear side of which body is formedan opening, the cylinder 22 extending upwardly from the rear end of the oval base and the tubes 25 extending upwardly from the body of said stove-base through the cylinder 22, of the removable draft-box 16 arranged against the rear side of the oval body of the stove over the opening therein, in the top and bottom of which box are formed alined openings, the flanges 20 formed intogral with and extending laterally from the lower edges of the sides of said box, in which flanges'are formed openings, the upper end of the oval cylinder engaging against the under side of said flanges 20 and the upper ends of the tubes 25 communicating with the openings in said flanges, and the damper 26 pivotally arranged in the lower forward corner of the draft-box and adapted to close the opening in the bottom of said draft-box or the opening in the rear upper side of the stove.- body, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.
