COOK-STOVE.

SPECIFICATION formingpart of Letters Patent No. 255,826, dated April 4, 1882,

Application filed December 20,1881.

'1' all whom'z't may concern Be it known that we, WILLIAM N. VINING,

of Southwick,Massachusetts, and EDWARD A.

QUESNEL, of St. Louis, Missouri, have jointly made a new and useful Improvement in Oil and Gas Cook-Stoves, of which the following is a full,clear, and exact description, reference being'had to the annexed drawings, making part of this specification, in which- Figure 1 is a view in perspective of a stove having the principal features of the improvement, the various doors of the construction being opened; Fig. 2, a detail upon an enlarged scale, being a view in perspective, showing I 5 the side plate of the detachable casin g at the front of the stove; Fig.3, a vertical longitudinal section of the stove; Fig. 4, a vertical transverse section taken on the line as so of Fig. 3; and Fig. 5, a detaiL-bein g a vertical section taken on the line 3 1 of Fig.

The same letters denote the same parts. The present invention has relation to the burners of the stove, the means used in supporting and inclosing them, and for supplying 2 5 air thereto; to the mode of directing the heatcurr'ents with relation to the heating of the oven; to the construction at the upper front of the stove, and to the movable rest immediately above the burners.

A represents a stove embodying the various improvements in question.

B B represent the burners or lamps used in heating the construction. One or more burners can be used, two or more being preferred. 5 They are so held in position in the stove as to cause the air used in supporting the combustion topass exclusively into the immediate vicinity of the burner-flames before passing into the combustion-chamber beyond or above, 40 and, saving such air-currents, no other air is admitted into the stove. The burners and the walls surrounding the burners are also so constructed as to insure a steady, strong, and sufficient air-current to the burners and to prevent any downward current to the burners. To these ends the burners B B are inclosed in casings C C, respectively, and the air-supply is admitted through apertures c c at or near (No model.)

the lower part of the casings, thenceconducted upward through flues c c, that contract at or toward their upper ends, and thence through openings d din a plate or diaphragm,D. The

admission of the air at c c is controlled by registers E E. 'The contraction in the flues c c is conveniently obtained by inclining the sides I) of the burners, as shown, and the openings cl (1 are in the immediate vicinity of, the burner-tubes b b, and preferably in the form of the slotted cones shown.

The casings C C are open attheir tops 0 c The burners B B are held in position in the casings by means of the projections b b resting upon the lugs or ledges c 0 upon the easings, and the latter in turn are properly supported in the stove, and the air entering the the stove properly directed, asfollows: The lower front of the stove is constructed to form and inclose a chamber, F, the top of which is the plate D, and the sides of which are shown at ff. The bottom f is made so as to admit air to the apertures cc. The sides may be in the form of doors, as shown at ff, Fig. 1,

to enable the casings to be reached and, with the burners, removed from the stove when desired. 7 5

The casings C C are provided with projections 0 c and the wallsf f \vithledgesf f The casingsare slippedinto thechamberE, the

projections 0 c bearing upon the ledgesf f The latter are inclined upward, as shown, the

effect of which is to cause the casings to rise in the chamber F as they are introduced therein and to bring the burner-tubes finally up into their proper positions beneath the plate D, as shown, and when thus in position the front ends of the casings are upheld by means of the books 0 c of the casings engaging in the eyesf The various parts of the chamber F and the casings C G are so relatively constructed as to prevent, when the casings 0 are in place, air from passing between the easings or either of them and the side wallor, walls of the chamber, the aim being to introduce the air into the stove at the bottom or lower end of and through the casings C C. 5 Hence the casings at the back come against the back of the chamber F, and at the sides against the ledgesf and at the front against the platef". Any other suitable means, however, may be employed for directing the incoming air in the manner described.

When two or more burners and casings are used in the stove the casings are separated by a suitable plate, f having the ledges f Perforated diaphragms c are extended across the casings, at or near the upper end thereof, for the purpose partly of subdividing the ascending the air-current and partly to prevent any accidental descent of the flames upon the oil-reservoirs b beneath. The oil is supplied to the reservoirs at b The heated currents and products of combustion pass from the burners into the chamber Gr, in the roof gof which are openings gg, similar to those in a cooking-stove top, and for a similar purpose.

Achamber, H, can be inclosed above the plate 9 by means of a casing, H, the latter being removable from the stove. The casing is composed of the side plates, h h, thelid h, and the doors k W, and it is preferably held in place by means of the lugs 7L3, engaging in the sockets h. In the doors h and at other points, if desired, of the casing there are registers h The noticeable feature of the chamber G is its extension upward for a considerable distance above the outlet 2' into the fine I. The latter extends beneath the oven J, thence upward at the farther side of the oven at I, and thence above the oven at 1 From the lastnamed flue, 1 the heated currents are conducted through the oven, entering the latter, say, atj, thence traversing the oven to the outletj, and thence into the flue K. From this point the heat-currents may be conducted eitherthrough the chamber H, and out finally through openings, such as in the registers h, or, when the casing H is not upon the stove, to the outerair through the outletkor through the flue K upward to above the flue 1 into an extension, K, and to the escape K according to the manner in which for the time being it is desired to apply the heat, whether to the chamber H, more especially, or to the oven J, or to the upper part of the construction above the oven. To enable the currents to be thus directed there are dampers, valves, or registers at all the various openings, ijj 7c It -that is, the passage 1' may be closed by the damper i, the passage j by the damper j, the passage by the damper f, and the passage by the damper k. There also may be a damper to close the flue K when the'escape is through the passage lo.

There are boiler-holes K in the top of the flue K, and a Water-reservoir, L, maybe used, -asshown. M represents a rest for the purpose of supporting cooking-utensils immediately in the vicinity of the burners. It is furnished with a handle, on, and when it'is to be used it is drawn out of the flue I and into the chamber G above the burner. When not needed it is slid back, as shown in Fig. 3, above the damper 'i, into the flue I.

An additional feature of the construction is the hearth N, which is extended around the front of the stovejustabove the level of the burners.

When it is desired to use only the front part of the stove the damper i is closed, or partly closed-that is, the damper may be tightly closed and the heated currents passed through the openings g g, the chamber H, and register k to the outer air, or, when the chamber H is not used, directly to the outer air through the openings g, and in passing through the latter openings a sufficient exit may often in practice be obtained from the loose fitting of the cooking-utensils in the openings g, or the damper 2" may be partially opened and the draft--obtained by allowing the currents to pass into the lines I I 1 oven J, and flues K K.

The advantage obtained from extending the chamber G above the outletw' is that the products of combustion are retained longer in the immediate vicinity of the burners and are accumulated inthe upper part of the chamber,-enabling them to be reheated and to become more thoroughly consumed before passing into the flue I.

When it is intended to use the oven J the heat currents are directed especially in that direction, the damper i being opened, the openings g closed, and the currents. taking the course indicated by the arrows in Fig. 3, passing into the oven at the inlet j, thence across the oven to the outlet 3', and thence into the flue K. By suitably operating the dampers 9' the heat-currents can be retarded in the lines I l I or oven J, so as to more effectively heat the latter. From the flue K the currents may be either to the open air or to the chamber H through the opening k or through the flues K K K or in both of the last-named directions, as indicated by the arrows in Fig. 3. All of the various dampers named are suitably furnished with rods k to enable them to be operated from without the stove. The heatcurrents may also pass from the flue 1 directly through the opening k to without the stove. Thelast-named opening maybe closed by a suitable damper, as shown, when not in use.

We claim- 1. The combination of the burner B, the easing 0, and the chamber F, substantially as described.

2. The combination of the chamber F, the ledges f f the casing G, the projections'e c, the hook c and eye f, substantially as described.
