To whomit may concern:

Be 1t known that I, HARRY CHIIJNGIRIAN,

a'citizen of Armenia, residing at Bridgeport, county of Fairfield, State of Connecticut, have invented a new anduseful Safety I (looking and Baking Stove, of which the following is a specification.

This invention relates to cook stoves, and

has for an object to provide an improved construction of stove for cooking purposes which may be closed when not in use to present a neat and attractive appearance, in

which during the cooking and baking operations the articles are entirely enclosed to conserve the heat and prevent escape of gases and odors, and in which means is provided to prevent manipulation of the gas burner valves by small children.

With the foregoing and other objects in view, I have devised the construction illustrated in the accompanying drawings, forming apart of this specification, similar reference characters being employed throughout the various figures to indicate corresponding elements. In these drawings,

Fig. 1 is a perspective view of a stove constructed according to my invention, the stove being closed.

Fig. 2 is a transverse section thereof. Fig. 3 is a partial longitudinal section and a partial fron't elevation.

Fig. 4 is a horizontal section substantially on line 4-4 of'Fig. 5. a

Fig. 5 is a transverse section through. the gas burner portion of the stove.

Fig. 6 is a detail view showing of mounting the flexible closure.

Fig. 7 is a detail showing of the means for mounting the flexible closure.

Fig. 8 is a transverse section of the upper part of the stove showing a different type of closure. 0 o

Fig. 9 is a detail showing of the means for one means mounting thetype of closure shown in Fig.

7 on an enlarged scale, and

Fig. 10 is a transverse section substantially on line 1010 of Fi' 9.

Referring to Figs. 1 to the stove oomprises'a bottom member 10, preferably of.

sheet metal, mounted on suitable supports, as the legs 11 of angle iron, the ends of tlie bottom member 10 being bent upon them- 7 selves, as shown at 12, for interlocking slidi g e g gement with similarly bent bottom edges 13'of upright end walls 14. The upright edges of these end walls are bent upon themselves, as shown at 15, for interlocking sliding engagement with similarly bent upright edges 16 and 17 of front and rear Walls 18 and 19 respectively. These walls form an enclosure or cabinet for the heating elements. Extending transversely of this cabinet is an upright wall 20 dividing the cabinet into two chambers 21 and 22. In the chamber 21 is mounted a grate 23 supported in any suitable mariner, as by mounting it on bars 24, and the sides of the chamber are protected by fire brick 25. At the rear of this chamber the rear wall 26 does not extend to the top wall or support 27 for the articles to be heated, some of which are indicated in outline at 28, but this rear wall is bent downwardly, as shown at 29, to .form a flue 30 .for products of combustion and a rear wall for the ashpit 31. Apipe 32 leads from the lower art of this flue 30 to the usual chimney, an the usual damper 33 is provided to controlthe draft. This damper is operated from the front of the stove by a handle 34 by turning the rod 35 having an arm 36 connected to the damper by a rod 37. A suitable damper 39 is also provided in the front 38,

and this front is preferably .hinged as .shown at 40. The usual lids 41 are provided in suitable openings in the top wall or support 27 over the fire box.

Inthe other chamber 22 are mounted fluid fuel burners 42, which may be for.

able-sliding shelves or supports 47 are provided in this oven for supporting the arti cles'to be heated. A flue 48 controlled by a damper 49 leads from this oven to the smoke pipe 32 to carry ofi the vapors or products of combustion. This damper is similar to the damper 33 and may be operated by the same type of mechanism from a handle 50 at the front of the stove.

Extending along the front of the top or support 27 is a chamber 51 in which the fuel supply pipe 52 for the burners 1s located, and branches lead from. the pi t the various burners controlled by the usual valves 53. Thes Valves are also located in this chamber 51 andthe top of this chamber is closed by a movable wall 54 hinged at its rear edge, as shown at 55. This wall is also provided with perforations 56 to allow entrance of air for the gas burners and also air for hard fuel fire. The pipe 52 is connected to any suitable source of supply by a pipe 57 which is preferably mounted in a space 58 at the outer end of the chamber 22 where it isprotected and is also out of sight. It may if preferred be covered with asbestos or other suitable fireproof material to protect it from the heat of the burners. It will be noted that in order to gain access to the gas control valves 53 the top wall 54 must be raised,as shown in Fig. 5.

The end walls 14 are extended a considerable distance above the top of the supporting wall 27, and they are connected at the rear of the stove by the upright rear wall 19, which also extends at a considerable distance above the top wall 27. The rear 7 wall 59 of the combustion chambers is spaced somewhat forwardly of the rear wall 19 to leave a space for the flexible closure 60. lihis closure is mounted to slide in suitable guides 61 carried by the end walls 14, and these guides extend from a point at the front of the stove above the top wall 54 upwardly, backwardly, and downwardly into the space 58, as shown in Figs. 2 and 5. lhe flexible closure is preferably of corrugated sheet metal, and in the corrugations of which are mounted rods 62 carrying at their ends rollers 63 running in the guides 61, these guides being preferably formed by a pair of rect'angular bars 64: secured to the end walls by any suitable means, such as rivets 65. At the front edge of the closure is a reenforcing bar 66 carrying suit-able handles 67 for manipulating the closure. By lifting on these handles the front edge of the closure may be raised and the closure brought to an upright position immediately in front of the rear wall 19 leaving the Whole top 'of the stove open for easy access to the articles supported on the top wall 27'. By pulling forwardly and downwardly on the handles' 67 this closure may be drawn to the position shown in Fig. 2 completely enclosing the top wall and the articles thereon in a chamber 68. This will tend to hold the heat about these articles, and will also prevent the escape of vapors and odors from articles being cooked in the room, a suitable flue '69 being provided leading from the upper portion of this chamber to the smoke pipe 32 and controlled by a suitable damper 70. It will be noted that when this flexible closure is in the position shown in Fig. 2, 01' closed position, that the reenforcing bar 66 forming the front .edge of the closure, rests upon the top of the top wall 54 effectively preventing the raising of this wall by small children so that they cannot reach the gas control valves 53.

If desired a warming oven 71 may be supported above this flexible closure by the rear and end walls, which may also be provided withv suitable doors 72. It will be apparent from an inspection of Fig. 2, that heat from the chamber 68 will have easy access to the bottom wall 73 of this oven by passing to the rear of the flexible closure.

In Figs. 8, 9 and 10,1 have shown a slightly different construction of flexible closure. In this case instead of being of corrugated sheet metal it is a plain sheet of flexible metal 74:, andin one of the bars 75 forming the guide 76 for this closure are mounted a plurality of anti-friction rollers 77 on suitable pins 78 upon which the closure runs. Otherwise the operation of this form is the same as in the first form.

It will be apparent from the foregoing description and from an inspection of the drawings that this stove will be neat and attractive in appearance, that when closed, as shown in Figs. 1 and 2, the various devices are all enclosed where they are protected from dirt and injury, that access may be easily had to the burners and the top plate by merely lifting on the handles 67 to move the flexible closure to a position in front of the rear wall 19, and that if desired the articles may be enclosed during the cooking operation to prevent waste of heat and also escape of odors into the room. When the closure is in the position shown in Figs. 1 and 2 access to the gas valve by small children is efleetively prevented.

Having thus set forth the nature of my invention, what ll claim is:
