GAS-STOVE.

Specification of Letters Patent.

To all whom it may aoncem:

Be it known that I, CHARLES W. WIL.

LIAMS, citizen of the United States, residing at 3313 Jamaica avenue, Richmond Hill, Long Island, in the county of Queens and State of New York, have invented certain new and useful Improvements in Gas- Stoves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a stove of that type having gas burners and intended for cooking purposes, and broadly the object of the same is to so construct the stove that the products of combustion from one burner, whether it stands in its usual position'or be inverted, may be utilized first to cook something and then conveyed through a channel beneath the stove top to another opening (preferably also having its own burner, although the same need not be lighted at this time) through which said products pass out and may be utilized a second time. This general object I accomplish in a novel manner as explained in the following specification, together with details of construction and operat-ion'.

In'the' accompanying drawingsFigure 1 is a perspective view of my improved stove when constructed with a box-shaped base adapted to be placed upon a table or other support, and without an oven; Fig. 2 is a central longitudinal section on the line 22 of Fig. 1; Fig. 3 is a cross section on the line 33 of Fig. 1; Fig. 4'is a horizontal section on the line 4-4 of Fig. 2; Fig. 5 is an enlarged longitudinal section of my reversible burner, showing the manner in which it is swiveled into the inner end of the air mixing tube; Fig. 6 is a perspective detail of another form ofburner which may be employed; Fig. 7 is a front elevation of my improved stove when constructed with an oven and intended to stand upon its own legs.

The body of this improved stove is by preference made of sheet metal and rectangular in plan view, and while the drawings show its top as provided with only two openings, it may be made large enough for a greater number aswill be understood.

The numeral 1 designates the back of the body, 2 and 3 are the ends, and4 is the closed bottom. In the views on the first two sheets,

.manipulated. Butas the box-shaped structure thus built up has corner posts 5 with feet 6 adapted to rest upon a table top or other support, and the front 7 is hinged as at 8 and provided with a handle 9 by means of which it may be shown in Fig. 2,.the bottom is disposed so near the top of the stove (yet to be described) that there is no oven, although space remains Within the body whereby broiling or toasting may be done as will be understood.

I might here say that the structure shown in Fig. 7 is a modification only to the extent that the bottom 40 is spaced some distance farther beneath the stove top, the corners or posts 50 are longer, and the feet are replaced by the legs so that a gas range is produced; and if desired to warm the oven at the lower partof the body, a separate burner 70 may be used for that purpose as illustrated. Otherwise the structure in this modified form is the same as will be described herein.

The specific form of burners employed in this lmproved stove is also susceptible of considerable modification without departing from the spirit of my invention, but in the drawings I have shown a ring burner 10 having slotted gas-orifices 11 and a straight tubular shank 12 forming its inlet; and in Fig. 6 is shown a modified type of burner wherein what might be called its head is of considerably difierent shape and greater area, but it has the same tubular shank 12. Opposite the latter in whatever type of burner is employed I form an arm 13 having a notch 14 in its front end, the arm standing in line with the axis of said shank 12 but in a plane below the head for a purpose to be described below. The air mixer 15 is also of any suitable form, excepting that it must have a tubular outlet 16 which is of a size to closely surround the shank 12 so that the latter may be revolved therein'and can be removed therefrom when desired.

The valves 17 are preferably disposed at the back of the stove so that they do not interfere with the opening of the front door' 7, will not be accidentally struck by the operator, and will be out of the way of meddlesome children, and to their plugs are connected rods 18 which lead to handles 19 at one end of the stove where they maybe reached by the operator. It is to be understood that if the stove is built with four, six, or more openings and burners, the latter Patented Sept. 10, 1912.

- tion.

may be of this type or of any preferred type so long as they possess the shank 12 and the arm 13 for a purpose to be set out below, and thedetails of the devices for admitting air and gas are not essential to this inven- The top of this improved stove comprises a fiat plate 20 with a surrounding skirt 21 of a size to inclose the ends and sides and the corner posts, just inside of which is a depending flange 22 to which the upright members are connected in the usual or any preferred manner; and the plate 20 is pierced with openings 23 for griddles 231 as shown at the right of Fig. 1 or a rim 233 with radial ribs 232 as shown at the left thereof and 'by preference slightly larger than the ring-shaped burners as will beseen in Fig. 2. Around these openings and within the body of the stove there depends from I said top 20 a casting whose outline for a stove of the, size being described is shown in dotted lines in Fig. 1. The casting comprises a curved wall 25 nearly. surrounding each opening 23 and producing a hood, and parallel straight walls 26 connecting said curved walls so as to produce a channel connectingthe two hoods. The lattershould be sufficiently large to permit the burners to be rotated on their axes from the position shown at the left of Fig. 2 to that shown at the right thereof. Such rotation is eflected by letting down the front door 7 and inserting a suitable instrument within the notch 14 at the front end of the arm 13, and then twisting it so that the shank 12 is revolved within the tubular. outlet 16 from the air mixer and the burner passes from the full lined position shown in Fig.

' and by the tube 16 alone, I preferably support the latter by some form of bracket 160 which may be led upward and connected as at 161 with the stove top,'or wlnch'may itself find other support. It is obvlous that when the front 7 is open and the operator deslres to employ someother form of burner, as for instance that shown in F1 6, she may withdraw the ring burner of Fig. 5 b rotating and as it were unscrewin 1t wit in the tube 16, and after it is with rawn shecan re lace it by the shank 12 of some other type 0 burner as for instance that shown in Fig.

6, and set. the latter either side up. The

. where. If trappe necessity for a variety of griddles will now be apparent. When a closed griddle is employed (made either all in one piece or in a number of rings as shown in Fig. 1) the heat rising from a burner at the right of the stove as seen in Fig. 2 will follow the line indicated by the arrows and will ascend into the hood from which it will pass across the channel to the hood at the left of the stove, whence it will pass out through the open grating there illustrated; and this will occur whether the burner at the right of the stove is set upright or inverted. In either event, the user gets the advantage of the heat twice, once where it is used either to heat this closed griddle or to broil as shown in the drawings, and a second time where it finds its outlet through the open lid or grating at the left of the stove; and therefore the burner herein shown at the left need not be lighted at this time. If it were not for the channel, the heat rising from either burner which is lighted would be spread out within the entire area of the stove body, heating all its upright parts as well as those portions of its top which are not used for cooking.

The fiat griddle shown at the right of Figs. 1 and 2 is made up of a series of rings 231 which are nested into each other. When all are used the bottom of a receptacle resting thereon is of course to an extent protected from the direct heatwhich reaches it only through the material of the griddle itself, but the heat trap ed by the hood is passed across beneath t e top of the stove along the channel 26 and out through the other griddle hole. When it is desired to apply more'heat to the utensil placed over this griddle, its center is removed, and if the size of the utensil will permit the innermost ring is removed;- but care should be taken not to remove so many rings as to permit any of the heat to escape from beneath the utensil if the heat is to be employed again at the other side of the stove. The skeleton griddle or grating-shown at the left of Figs. 1 and 2 is made up of a series of raised radial ribs 232 mounted upon a rim 233 which fits accurately within the stove-hole 23 and has an opening 234 through its center. When a utensil is placed upon this griddle or grating as seen in Fig. 2, the heat rising from within the stove is forced by the rim 233' to and toward the center passes up through the opening 234 directly against the bottom of the utensil, whence it passes radially outward along the same between the several ribs 232. The necessity for a iddle of this character in a stove of this kind will now be apparent. As the same has no hole for outlet of the :products of combustion into the chimney,

all heat must escape out the stove top someat the right by a closed I but when the burner griddle or a large utensil sitting over the griddle hole there,-the heat flows to the left and is used a second time heating the utensil at this point, but must find some escape; and the fact that the ribs 232 hold the utensils spaced above the rim 233 becomes important because it pfoduces openings through which the products of combustion -may passoutalthough they are utilized a second time in the act of doing Another detail of construction which may be employed with advantage is that the burner 10 by preference has a surrounding integral flange 100. When this burner stands upright as seen at the left of Fig. 2, the flange of course has no influence upon the flames issuing through the openings 11; is inverted as seen at the right of Fig. 2, the flames issuing through the gas orifices 11 are spread by this flange 100 so that their efliciency is increased without the necessity for using a large burner which would consume much gas. However, the flange should not be of greater diameter than the circular wall 25 of the hood above this burner, because the heat rising from the latter must be trapped in a manner explained above.

What is claimed as new is:

1. In a gas stove, the combination with the stove. top having a plurality of openings, depending walls around such aopenings forming hoods, and walls forming a channel connecting said hoods; of a burner located beneath each. opening and comprising a ring-shaped head having orifices in one ace and a surrounding radial flange whose cir-' cumference is less than that of the wall of the hood above'it, and means for supporting said burner head either side up.

2. In a gas stove, the combination with the stove top having a plurality of openings, depending walls around such openlngs forming hoods, and walls forming a channel connecting said hoods; of a burner located beneath each 0 ening and comprising a ring-shaped head having orifices in one face, a surrounding radial flan e whose circumference is less than that o the wall of the hood above it, and a tubular shank projecting radially from said head, a mixer having a tubular outlet in which said shank a hood; of a source of gas supply, an air mixer connected therewith and having a tubular outlet projecting into the rear of the stove body, a burner disposed beneath said opening in the stove top and having a tubular shank swivelly mounted in the outlet from said mixer, an arm projecting forward from said burner and having a notch in its frontend, and a door in the front of the stove-body which when opened gives access to said notch.

4. In a gas stove, the combination with the'body having a plurality of openings in its top, closed and open-work lids therefor, and a wall depending from said stove top and forming a hood around each opening except at one side thereof and a channel connecting the open sides of said hoods; of a source of gas supply, air mixers connected therewith and each having a tubular outlet projecting into the rear of the stove body, a burner disposed beneath each opening in the stove top and having a tubular shank swivelly mounted in the outlet from one of said mixers, an arm projecting forward from said burner and having an irregular front end, and a door in the front of the stove body which when opened gives access to said arm, the lower edge of said wall being sufficiently elevated above the axis of rotation of the burners to permit the latter to be set either side up.
