To all 2'0 7mm it may concern:

Be it known that 'I, GEORGE IV. How'ns,a citizen 'o'f the United States, residin at 'Dowagiac, county of Cass, State of lVIichigan, have inventedcertain new and useful Improvements in Combination Solid-Fuel and Gas Ranges or Cooking-Stoves, of which the following is a specification.

combination solid fuel and gas ranges or cooking stoves. I

The main'ob-jects of this invention are:

First, to provide in a combination solid fuel and gas range or cooking stove an impro'i ed oven structi'ire which is very effectively heated either by solid fuel, such as coalfo'r wood or by gas.

4 Second, to provide an improved combination solid fuel and gas range or stove which may be conveniently converted from one to the other. I

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification. I The invention is clearly defined and pointed out in the claims. I I

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing, forming a part of this specification, in which:

Fi ure I is a'detail front perspective view of a structure embodying the features of'my invention, with the oven adjusted to be heated by solid fuel.

I Fig. II is a front perspective view of my improved stove adjusted to heat the oven by as.

I Fig. III is a perspective view of the base of my improved stove showing the support for the burner plate and burner when'not in use, the support being released and the burner plate in position as discharged therefrom. I I

Fig. IV is a perspective View of the base with the burner plate supported therein.

Fig. V is an enlarged detail vertical section one line corresponding to line 5-5 of Fig. IV, showing the-latch for the burner plate support. I I

Fig. V1 .is enlarged detail vertical section on aline corresponding to line 6-6 of Fig. V, with "the burner in position in the oven, the burner coupling being shown in operative position by dotted lines and 1n reti'acte'd position by full lines, the operating mechanism being shown in full lines.

Fig. VII is an enlarged detail section through the'burnerand burner plate and the gascoupling, showing the coupling in operative relation to the burner. Th s inventlon relates to improvements in I "Fig. VIII is a detail bottom view of the air damper and its operatin connection. I In the drawing similar re 'erenc'e characters refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the'ends of the section lines.

Referring to the drawing, 1 designates the stove body generally and Q the base which is provided with legs 3. I desire to point out that I have not, in the accompanying drawing, attempted to maintain the relative proportion of the parts, nor have I attempted to show strnctural features of the'body proper nor the joints or connections 'for'i t s several parts, as snch details will be readily understood by those skilled in the art to which my invention relates. I I I The "oven 4L in the structure illustrated is positionedasis "common practice. The firepot and ashpit are at the left hand but, as thesedetails form no part of this invention, I have not illustrated them herein. The flue from "the firepotextends over the top of the oven, downwardly at 3 and under the oven at 4:, this flue arrangement "being wellknown in the art. I I I The bottom 5 of the oven is provided with a central opening 6. The bottom 7 of the flue has an opening '8 alined with the opening'6. An air flue 9 in the heating 'fiue'conmeets these openings 6 and I8. The'botto'm of the oven forms the top wall of the heating fine.

A the heating flue and has a vertical delivery portion 11 disposed centrally of the air flue 9. Below the air fine is a damper box 12 having damper openings 13 controlled by gas delivery pipe 10 is arranged under 0 the damper I l pivoted at 15. The burner 16 is mounted on the under {side of the burner plate 17 which is removably mounted in theoven so as to supp'ortthe burner in a spaced relation to the bottom of the oven and the burner plate with its ,'edges in a spaced relation "to the walls of the even-.-

In the structure illustrated the burner plate is supported by thearms 18 which engage the shelf ledges 19 of the oven. The burner is preferably mounted for limited vertical movement, being mounted, in the structure illustrated, on the headed pins 20 which engage lugs 21 on the burner.

The burner has lugs 22 which limit its movement toward the plate. The burner,

in the structure illustrated, has a central crossportion 23 with a chamberor passage therein communicating with the chambered 'andalso the burner being loosely mounted may be lifted by and partially supported on the coupling member, thus insuring a perfect connection and also accommodating-for irregularities in manufacture and any war ing or displacement of the parts that mig t occur 1n use. I j V V The opening 6 is provided with a removable cover or closure 28. The gas coupling member, in the structure illustrated, is actuated by the lever 29 which is pivoted at 30 and slotted at 31 to receive a pin 32 on the collar 33 of the coupling member, the collar being threaded upon the coupling member to provide forconvenient adjustment of the coupling member. a

The actuating lever 34 is. pivotedat 35, the

pivots

30 and 35 being preferably mounted on the gas supply pipe 10 and connected with the lever 29 by a ball and socket connection shown conventionally at. 36.

The damper 14 is connected by the link 37 to an arm 38-on the lever 34, so that by the actuation of the lever the damper is opened and closed and also-the burner is connectedand disconnected with the gas supply. 7 The gas delivery pipe 10 is, in the structure illustrated, a Bunsen tube, the gas being delivered thereto by the-pipe 39 con: trolled by the valve 40. This valve, which is located atthe rear of the stove, has an actuating shaft or rod 41 extending'to the front of the stove and provided with a handpiece and index 42 which not only indicates when the valye is its closed position, but also the degree of opening of the valve. To insureconnection to the burner when the valve is opened the shaft 41 is provided with a crank 42 which engages a slot 43 in a bar 44'connected at its lower end to theend of thelever 34 and slidably supported at its upper end. With this arrangement the valve cannot be opened without the gas couranged on this rack in an inverted position and the rack swung up to the position shown in Figs. IV and V, so that it is entirely concealed and out of the way. A push on the latch 47, with'the foot releases the rack so that its front end drops down as shown in Fig. UT and the burner plate slides out under the base andv can be readily picked up and shoved into the oven.

For convenience in lighting theburner I provide a pilot 48, the front end of which projects through a flange 49 on the front ed e of the burner plate.

My improved combination solid fuel and gas stove is very efficient both when used with solid fuel and when used with gas. The structure is easily adapted forthe use of either fuel. I have illustrated and described my improvements in one, form in which I have embodied the same for the market. I have not attempted to illustrate or describe other .embodiments or adaptations as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, isz.
