STOVE.

SPECIFICATION forming part of Leners Patent No. 706,589, dated August 12, 1902. Application iiled September 4, 1901. Serial No. 74,300. (No model.)

To a/ZZ whom it may concern:

Be it knownthat 1,-W1LLIAM NULL,a citi`4 zen of the United States, residing at Philoah, in the county of Putnam and State of Ves't Virginiaphave invent-ed aV new and Vuseful Stove, of which the following is a specification.

' This invention'relates to stoves, and is particularly designed to provide an improved cooking-stove, wherein the re-boX is located so as to effectually heat both the cooking-oven and the warming-oven and also disposed so as to form a convenient support for a watertank, and thereby to leave the top of the stove unobstructed for cooking vessels and the like. It is furthermore designed to employ a single damper for controlling the supply of heat for the two ovens and to have said damper l0- cated in position for convenient adjustment.

Another object is to provide for convert iently supplying fuel to the fire-box without removing the watertank therefrom and'also to provide an, improved grate-and ash-pan arrangementwherebythe grate may be conveniently removed whenever desired and is normally held against displacement by the ash-pan. s

With these and other objectsin view the present invention consists in the combination and arrangement of parts, as willbe hereinafter more fully described, Ishown in theaccompanying drawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure l is a perspective View of a stove constructed and arranged in accordance with the present invention.` Fig. 2 is a longitudinal `sectional view thereof. Fig. 3 is a detail sectional view taken longitndinally'through the fire-box. Fig. 4 is an enlarged detail sectional view taken transversely through the front of the fire-box. Fig. 5 is an enlarged detail sectional view taken through the damper-operating mechanism. Fig. 6 is a detail elevation of the means for 5o locking the damper.

Like characters of referencedesignate corv responding partsin all the figures of the drawings.'

In carrying out the present invention there is provided a substantially rectangular stove- 4body 1, whichhas anupper cooking-oven 2 and a lower warming-oven 3, said ovens being separated by a. space or 'lue formed between the bottom and top of 'the ovens, there being a plurality of longitudinal ribs 4:' located within said space or flue to stiften and strengthen the bottom and top plates. The warming-oven extends from the back to the front of the stove, while the cooking-oven is terminated short of said front and rear ends by means of the front and rear plates 5 and 6, respectively, and the top of the oven is formed by means of atop plate 7, located slightly below` the top of the stovetop,whereby a ue or V`heat-passageis provided that extends entirely around the cookingbven and also between the two ovens. The cooking-oven is provided with the I opposite hinged doors 9 and also with a removable rack 10,'tl1`at may be held on either of t'ne corresponding pair of flanges 10,formed Yin the front and rear Walls of the oven. rlhe .warming-ovenis also provided with doors 11,

one of-which has a plurality of draft-open ings which` arefcontrolled by means of a damper-slide 1.2, mounted upon the inner side of the door and having a handle 13 pro- `jeetedoutwardly through a longitudinal slot formed in the door.

The fire-box 11iE is supported upon a front extension of the bottom or base ot' the stove and has its top 15 located substantially in line with the bottom of the cooking-oven, and

-is"also provided with the usual stove-holes. It will herebe noted that the nre-box is projected in front of the stove and forms a support or seat for a water-tank 16, whereby the top of the stove is unobstructed and the 'water-tank receivesthe full benefltof` the fire. A suitable hinged shelf 17 is provided at one end of the top of the fire-box, so that the water-tank maybe moved outwardlyand partly supported by this shelf should it be desired to expose a greater portion of the top of the fire-box. Ordinarily the watertank will be somewhat shorter than the rebox in order that a portion of the top thereof Inay always be exposed for the support of` IOC ' mally closed by a suitable door 21.V

' rest upon the bottom of the fire-box.

such cooking utensils as may require an intense heat. f

Within the fire-.box there is provided a grate which consists of a slotted bottom 18, having opposite outwardly-directed longitudinal iianges or ribs 19, that are slidably received within corresponding grooves 20, formed in the front and back of the lire-box, the grate being insertible through a doorway provided at one end of the lire-box and nor- The bottom of the grate is also provided at its four corners with supporting-feet 22, which The grate also has-the front and rear longitudinal walls or sides 23 and 24, respectively, of which the front side is provided with a pluralityof openings 25, which register with corresponding openings 26, formed in the front of the fire-box, so as to supply air to the fire. The opposite ends of the grate are open and are normally closed by means of the opposite ends of the fire-box. The grate maybe readily shaken by opening the door 21 and applying a hooked poker through the adjacent slat in the bottom of the grate, and is also designed to remove-the grate in an endwise direction through the door.

In orderthat fuel may be supplied to the grate without removing the water-tank from the top of the lire-box, an opening 27is formed in the front of the lire-box and is closed by means of a door 29, which is located upon the outer side of the fire-box and hinged at its lower edge, there being a suitable latch or fastening 30, located at the upper edge of the door, so as to normally lock the latter. At opposite sides of the fuel-opening there is provided the upright plates 31, which are suitably secured or formed integrally with the front of the fire-box and having their outer edges inclined upwardly and outwardly and provided with inwardly-di rected longitudinal ribs or flanges 32. The door 29 fits between these plates and is limited in its outward movement by means of the flanges 32, so that when the door is opened it cooperates with the opposite plates 3l to form a chute or hopper for convenience in introducing the fuel to the fire-box. 1

Beneath the grate there is located an ashpan 33, which has its outer end projected through an opening 34, formed in the front of the fire-box, the outer edge of the pan being provided with a plurality of notches or recesses 35, which communicate with the interior of the pan. The notched frontedge of the ash-pan is normally projected beyond the front of the lire-box, and upon this edge there is mounted an endwise-slidable damper-plate 36, which is provided at its inner edge with a plurality of notches 37 to register with the notches in the pan to provide passages for conveying air into the lire-box and beneath the grate. When the ash-pan is in place, it iits snugly between the legs of the grate, and

damper to an intermediate position between the horizontal and upright fines the products of combustion may pass entirely around the cooking-oven, and by adjusting the damper to close the upright flue all of the heat and products of combustion may be directed .between the two ovens, so as to apply more heat to the warming-oven, land by closing the vhorizontal i'lue all of the heat and products of combustion will pass upwardly and over the top of the cooking-oven and iinally out through the smoke-pipe of the stove without having any eiect upon the warming-oven.

To provide for the convenient adjustment of the damper, one of the journals thereof is projected beyond one side of the stove, as indicated at 39, and upon this projected journal portion a slidable sleeve 40 is mounted, said sleeve being provided at its outer end with a crank-handle 41 and at its inner end with a lateral ratchet finger or projection 42 for cooperation with an arcuate rack 43, applied to the adjacent side of the stove. Within the sleeve Athere is provided a suitable spring 44, which bears in opposite directions against the sleeve and the journal, so as to yieldably hold the sleeve at its inward limit with the finger or projection 42 in yieldable engagement with the rack, so that by manipulation of the crank-handle the damper may be readily adjusted and the ratchet-finger will work over the rack and finally lock the damper at the completion of the adjustment thereof; also, the damper may thereby be held at a plurality of adjustable positions, so as to vary the size of the opening between the fire-box and the two lines.

What I claim is- 1. In a cooking-stove, the combination of a lower heating-oven, a cooking-oven located above the same and havinga flue surrounding the top, bottom and opposite ends of the cooking-oven, the top of the heating-oven and the bottom of the cooking-oven forming the walls of the flue portion between the two ovens, and the bottom of the lower oven being formed by the bottom of the stove, a tire-box projected in front of the heating-oven and having its top located below the main top of the stove and above the top of the lower oven to form a seat or support for a water-tank, the back of the fire-box being terminated substantially at the top of the lower oven, whereby a direct communication is had between the hre-box and IOO IIO

the flue or space between the two ovens, and a vertically-swinging damper pivoted substantially at the intersection of the inner edges of the front and bottom flue portions and capable of swinging vertically toward the ire-box to open and close the lower end of the vertical flue and the front end of the horizontal fine, whereby either of these fines may be Wholly closed.

2. In a stove, the combination with a rebox, of an endwise-removable grate having legs, and an ash pan inserted through an opening in the front of the fire-box and lying snugly between the legs to prevent accidental displacement of the grate.

3. In a stove, the combination with a firebox having draft-openings formed in the front thereof, and a door at one end, of a grate insertible through the door and having draftopenings corresponding to the similar openings in the fire-box, and an ash-pan removably inserted through an opening in the front of the fire-box and having its outer end normallyprojected externally of the lire-box, and a slidable damper mounted upon the projected portion of the ash-pan.

In testimony that I claim the foregoing as my own I have hereto afxed my signature in the presence Vof two witnesses.

WILLIAM I-I. NULL.
