CLARENCE R..GRAHA1VI, OF NEVTARK, CALIFORNIA.

T 0 all whom it may concern:

Be it known that I, CLARENCE R. GRA- HAM, a citizen of the United States, and a resident of Newark, county of Almeda, and State of California, have invented a new and useful Combined Gas and Coal Range, of which the following is a specification.

My invention relates to improvements in cooking stoves.

Since the general adoption of gas stoves for cooking purposes, it has been the practice to attach coal and wood burning stove.

or side of the gas stove and some means of.

attachment is employed to secure the stoves togetherso as to bring the fronts and cooking topsthereof into proper relation. If the gas stove hasan oven vent p pe, such pipe is, extended over and acrossthe tops of' the stoves and joined to the stove pipe of the heater, both pipes being plalnly vlslble.

In instances where the heater has a gas,

kindling or trash burning burner, apipe connection thereto from the gas stove must be made.

In all, the advantages and conveniences attending the use of a combined stove of the above type made up of separate stove units, are nearly eclipsed by certain disadvantages and objections such as, first, the provision of eight stove legs, six of whlch are bunched at one end of the combined structure, which makes sweeping diflicult, are unsightly, take up too much floor space, and render the structure cumbersome, second, the exposure ofboth stove and oven vent pipes and the extension of the oven Vent plpe over and across the cooking tops, which adds to the unsightliness and space consumptlon of the combined structure, and third, the necessity ofma'tching thelstove units as to size so as to dispose the fronts'and cooking tops in proper position, which means that a large number of attachment units or heaters of different styles and sizes must be made in order to beapplicable to the many kinds and sizes of gas stoves. The result of this last objection is that many misfit heaters are at COMBINED ens AND COAL RANGE.

Specification of Letters Patent. Patented :Allg. 24 1920 Application filed September 15, 1919. Serial No. 323,823.

tached and the tops and fronts of the gas stove and heater are not flush and cannot to removethe. hereinbefore noted objections and disadvantages in combinedstoves of the V kind hereinbefore discussed, by providing a combined gas and coal stove or range con structed in one single, compact, relatively small unit and which is more durable, or namental in appearance, simple as to construction, less expensive and takes up less room than stoves made up by attaching a kitchen heater to a gas stove.

Another object of my invention is to provide acombined gas and coal range of the character described, in which the frame elements are so constructed and arranged that, oven, broiler and warming chambers, gas burners, a coal and wood fire box, warming shelves, cooking tops for the burners and fire box, and other stove elements, may be compactly arrangedandrelated in a manner most convenient for their individual or collective use, and so that a saving in space and material is provided. Y j Y A further object is to provide a stove of the character described in which the stove pipe and oven vent pipe are arranged so that the vent pipe is entirely concealed, and the stove pipe is partly concealed and disposed in an inconspicuous and out-of-theway position.

The invention possesses other features of advantage, some of'which, with the foregoing, will be set forth in the following de scription of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. it is to be understood that I do not limit myself to the showing made by the said drawings and description as I may adopt variations of the preferred form within the scope of my invention as set forth in the claims.

Referring to the drawings:

Figure 1 is a perspective view of a combined gas and coal range constructed in accordance with my invention.

Fig. 2 is a rear elevation of the range showing the arrangement of stove and oven vent pipes.

In construction my invention comprises a preferably horizontal rectangular bottom stove frame 1 which consists of side bars 2 joined at their ends to end bars 3 and 4 and supported at the joined ends by legs 5, 6, 7 and 8.

A horizontal cooking top frame 9, of pref erably rectilinear outline, and comprising side bars 10 and 11 joined to end bars 12 and 13, is mounted in superposed preferablyparallel relation to the bottom. frame 1. The frame 9 is of preferably the same width as and ofsubstantially two-thirds the length ofthe frame. 1, and is arranged with: the bar 12 at the outeinend thereof, directly over and secured. to. the wall 15 and bar 13 atthe Abottom wall 17. is secured to the bottomframel and closes inner end of .the.frame 9.

that pprtion of the-space between the frame bars of the. bottom frame, that is located under the frame 9.- These walls 14, 15,16 and 17 siipport the frames in position.

Arranged between .the alined ends of the frames1and 9. and preferably. occupy ng substantially one-third of the. space between the frames is a fire box 18 for burning wood,

coal and similar fuel. A'fire box. door 19 of the usual type is mounted to open and close. on the front of the stove in the. ordinary manner. holes therein closed bylidsfl21 is mounted in the frame. 95 and closes the upper side of,

the fire box. Abar 22 joined at its end to the bars 10 and llioftheframe 9 extends acrosscthe; frame and with thebars 10, 11.

and '12.supports the cooking top-, in. the ordinary manner. The fire box interior may beof any .desired standard. firebox construction and it is. not thought :necessary to illustratetor-describe the detail construction of the box. I I

A vertical partition. wall 23 secured to the side frame bars of the frames 1 and 9, and engaging the bottom wall, divides the space occupied .by the fire box. from the rest of thespace between the frames and defines withthe-walls 15, 16-and 17 a warming chamber ,24 which is open along the frontside thereof to permit of access thereto.v

Mounted justbelow the frame 9 within the confines of said frame are a plurality of gas burners 25 of I standard construction. These burners aresupported inthe usual mannenon pipes .26 leading thereto from a gaspipe 27. connectedto. a supplyline, not shown, which pipe 27 extends alongthe front of the stove, being supported'in brackets'28. The ordinary valves 29-are provided forthe pipes26:v Agrated cooking top 30 of the ordinary construction-is supported .inthe frame 9 by the bars 10, 11, 13 and 22 of said A cooking-top 20=having two frame. The top 30 is arranged to lie substantially flush; witlnthebars 10, 11, 12, and 22 and the top 20, so cooking utensils may' b'e-conveniently and easily moved or slid from one top to the other. A drip pan 81 is mounted in the chamber 24 beneath the.

burners A stove element 32 is mounted on the bottom frame 1 on the end thereofioppositethe firebox and is connected to'theinner end of the frame. 9 and extends above, the. frame.

This element is divided horizontally, in,,a.

plane aliningwith theplane of :the. frame. 9,-

by a wall33 and forms a bake oven .34 in,

the upper. portion thereofand.abroiling. chamber in the. lower part.

illustrated and described... Both .the oven and the broiling .cha-mb'er have downwardly openingdoors 36 on the frontsides thereoff The wall 16. may. be considered as arwall :of.

th'ebroiling chamber. andthewall .15 joins with therear wall 37 ,of said. chamber. where? as the outer wall 38 of said chamber.-ma.y--

extend upwardly to form. the. corresponding wall 39. of theoven. A wa ll 40 extending as V 211001113111115117101'1- ofthe wall 16 constitutes the. innerv side. wall of the oven, and a. wall .41.

secured to-the-walls Y39 and 40 and to. 'aitop wall 42constitutes the rear wall of the oven- The top wallefthe. oven ser ves .as a ,shelf.

and has an extension. 43. which proj BCtSzOYGl the cookingtops 20 and 30'to a point in line 7 with the end. .of the,v frame. 9 and'serves. as. a

shelf. Aibracket 44 supports the outerend of this extension.-

An uprightwvalh .45 issecured-to thewalls 15 and 41 and extends above the frame9fortheentire length thereof. This wall extends above-theshelf or extension 43 fonthelength of-.said.shelf andupper wall 42, is secured to said extension .and supports. the. bracket 44. Substantially all.of the wallsofthe stove are permanently. connected and. secured or-engage. one. another so. that :the entire structure isri'gidand strong, some of the. -walls servingas closures for separate.

parts of the. stoves at some time. Like the.

walls, the. stove elementsare. all interconnected and arranged to economize in space and to.be.read-ily accessible as well.

An ovenvent pipe. 46. is. connected with the oven 34and chamber-.35 in anysuitable Suitable. gas burners are arrangedwithin the. ovenand broiler elements in this stove. element, not shown, and asthese constructions .are well. known-and standardized. they need not be.

the pipe 47, the latter being connected with a chimney or flue, not shown. Thus, the vent pipe is entirely hidden from view from the front of the stove and the stove or flue pipe is partly hidden. A gas, kindlingburner 49 may be extended into the fire box from the pipe 27 which pipe extends in front of the fire box.

I claim:

1. A combined gas and coal range having a bottom structure with corner legs, a firebox in one end of the bottom, a top for said box, superposed baking and broiling ovens on the other end of said bottom and spaced horizontally from the fire-box to provide a chamber having an open front and a closed back therebetween, a set of gas burners arranged at the top of said chamber, a plane grating coplanar with the said top and above the gas burners, a drip pan below the burners and forming a top for said chamber between the said box and said ovens, one of the ovens being below and the other above the plane of said burners, and a gas service pipe extending along the front of top structure and having a kindling burner to the fire-box.

2. A combined gas and coal range having a bottom structure with corner legs, a firebox on one end of the bottom, a top for said box, superposed baking and broiling ovens on the other end of said bottom and spaced horizontally from the fire-box to provide a chamber having an open front and a closed back therebetween, a set of gas burners arranged at the top of said chamber, a plane grating coplanar with the said top and above the gas burners, and a drip pan below the burners and forming a top for said chamber between the said box and said ovens, one of the ovens being below and the other above the plane of said burners.

In testimony whereof I have hereunto set my hand at Niles, California, this 5th day of September, 1919.
