GAS-RANGE.

Specification of Letters Patent. Pat t June 13, 191

Application filed February 17, 1914. Serial No. 819,273.

To all whom it may concern.-

Be it known that I, GUY B. CHILD, a citi- Zen of the'United States, residing at Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements in Gas-Ranges, of which the following is a specification, reference being had therein to the accompanying drawmg.

y gas ranges.

The object of my invention .is to provide a gas range having an air-inlet and exit so arranged and connected to the gas controlling valve that the opening and closing of the gas valve opens and closes the air-inlet and exit, whereby the heat of the oven is retained and at the same time providing means whereby the burners cannot be lighted without the inlet and exit openings being opened and thus avoiding any liability of explosion in the oven.

Another object of my invention is to provide means whereby the passage of the products of combustion are utilized for heating the oven and when the burner is extinguished the heat accumulated thereby is utilized in further cooking the articles in the oven and maintaining the oven at a high temperature.

A further object of my invention is to provide a simple, cheap and effective oven of this character having certain details of structure hereinafter more fully set forth.

In the accompanying drawing: Figure 1 is a perspective view of my improved oven, showing the valve and damper operating means and showing the burner and lower damper in dotted lines. tive view of the bottom of the oven, showing the relative position of the burner and the lower damper. Fig. 3 is a vertical transverse sectional view of Fig. 1 showing a fine oppositethe-upper damper. Fig. I is a horizontal transverse sectional view taken on the line 44, of Fig. 3, and showing the burner and the lower damper in dotted line.

In the ordinary gas range, it is necessary to have an air-inlet at the lower end of the oven to supply the proper amount of fresh air to the burner to cause combustion, and also to provide an exit opening at the upper end to allow the heated air and products of combustion to pass from the oven. In such ovens these'openings have been of such a invention relates to improvements m cause perfect combustion.

Fig. 2 is a perspecp stove on the inside of the door-'3, is a tube character that when the burners have been extinguished the oven is still supplied with the air and the heated air also passes from the oven. This allows the oven to become cool in a very short time and also allows the same amount of air to be supplied and discharged from the oven when the burners are running full, or only partially burning. This, as Wlll be readily understood, supplies the oven with more air than is necessary to cause the proper combustion and thus it takes more gas to heat the oven at the desired temperature than is the case with the device which I will now proceed to describe.

The oven 1 is of the usual rectangular form and supported by feet 2 and having at its forward side the door 3, which is located some distance above the bottom 4: of the oven and below the top 5. .All of this is of the usual construction and needs no further description. The bottom 4: of the oven is provided with a hinged damper 6, hinged by a horizontal pivot 7, the outerend of said pivot extending outwardly and having an offset portion 8 extending beyond the side 9 of the oven. The extreme outer end of the offset portion 8 of the pivot 7 is bifurcated, as indicated at 10, and to which the operating means is adapted to be connected, as hereinafter more fully described. a

Within the oven, above the opening 6, which is closed by the damper 6, is a burner 1%),1 which is of any desired form but prefera y which surrounds the opening 6 and whereby through the opening 6 the proper amount of air is supplied to the burner to Extending inwardly from the front of the 12 which is slightly inclined and extends adjacentthe burner 11 and has an enlarged portion 13, which is adapted to straddle the space between the tubes 14 and 15 of the burner and communicates with the gas-discharge opening 16 therein. By this structure it will be seen that in order'to light the burner it is only necessary to open the oven door and apply a match to the outer end of the tube. The gas in the tube 12 is ignited and travels down and ignites the two tubes 14 and 15 at one end and the flame then travels across and ignites the entire burner, all of which will be readily understood.

Above the burner 11, is a heavy-cast-metal plate 17 which has its rear edge spaced a distance from the rear wall 18 of the oven and leaving a space 19 for the products of combustion and heated air to pass upwardly =r into the oven proper 20. This plate 17 is closed by a damper 22, the pivot 23 of which extends outwardly beyond the side 9 of the oven and is provided with a laterally turned portion 2e. having its outer end bifurcated at 25. Extending transverse the oven, be-

, low the opening 21, is a heavy cast-metal plate 26 which divides the oven and forms a passage 27 across the upper end thereof. The forward end of the plate 26 does not extend to the front of the oven, thus leaving a space 28 through which the products of combustion and heated air pass into the passage 27 and out through the opening 21 and are discharged to the atmosphere. The products of combustion engaging both the lower and upper faces of the cast-metal plate 26, it will be seen that the same will become heated and when the oven is shut up this plate throws off its heat and keeps the oven hot for a great length of time. Surrounding the discharge opening 21 is a vertically disposed flue 29, which, if desired, can be connected to the chimney.

The burner 11 is supplied with gas through the pipe 30, which is supported by the brackets 81, and said pipe carries the valve 32 through which'the air passes to the funnel-shaped member 33 and by means of which the burner is supplied with the proper amount of air and gas. The valve 32 is provided with a valve-stem 34 carrying a bifurcated arm 35 between which is pivotally connected a bar 36. This bar 36 extends upwardly and has its upper end screwthreaded into a socket 38, pivotally connected at 39 to thearm 39 of the member 40. This member 10, as shown in Fig. 1 of the drawing, is pivotally mounted upon the pivot 41, carried by the plate 42, said plate being riveted or bolted to the side 9 of the oven. The member 40 is provided with an arm 43 to which is pivotally connected the socket as and to which is screwed a rod 45, the lower end of which is pivotally connected between the bifurcated end 10 of the pivot of the lower damper 6.

The member 41-0 is provided with an up- 7 wardly inclined arm to to which is pivotally connected a socket and into which is screwed a-ro'd 458, and the outer end of the said rod is pivoted within the bifurcated end 25 of the pivot 23 of the chamber 22. The rods 36, 4:5 and 48, as heretofore described, have screw-threaded connections with the sockets 38, 44 and 47, whereby said rods may be adjusted so that the dampers and also the valve will be thrown the proper distance to open and close the same.

The plate 10 is provided with an outwardly extending operating arm a9, which is adapted to engage the segment 50, carried by the side 9 of the oven and whereby the lever is held in its adjusted position. By this segment it will be seen that the lever 19 and the plate -10 are held in any position so that the burner is closed, opened or partially opened and when in such a position the lower damper 6 and the upper damper 22 are in a corresponding position. The lever 49, as shown in Fig. 1 of the drawing, is in a position with the gas full open and the upper and lower dampers also open. lVhen the lever is swung down to the closed position, as indicated at the lower end of the segment 50, the gas will be entirely out off and the dampers 6 and 22. will be closed, whereby the oven is tightly closed and will retain its heat.

Vhen the gas is entirely cut off and the dampers 6 and 22 are closed, as heretofore described, it will be readily understood that there being no air supplied or discharged from the oven, the oven will be kept at a higher temperature for a greater length of time than is the case with the ovens now in use, in which air is supplied and discharged after the gas is cut ofi. The cast-metal plates 17 and 26 throw off considerable heat and greatly aid in maintaining the high temperature of the oven for a greater length of time.

Having thus described what I claim and ters Patent is:

1. The combination with an oven, of a burner therein, a gas controlling valve for the burner outside of and located at one side of the oven, the oven having an outlet opening at its top and an inlet opening at its bottom, pivoted dampers for the said openings having their pivots extending to the same side of the oven as the gas valve, an operating member composed of a plate pivoted to the same side of the oven as the gas valve, said plate having four integral arms extending radially therefrom in substantially the same vertical plane, two of said arms extending substantially horizontally therefrom and connected respectively my invention, desire to secure by Let- 'with the gas valve, and with the pivot of the lower damper, the other two arms extending upwardly, one of the upwardly extending arms being short and operatively connected with the pivot of the upper damper and the other upwardly extending arm elongated to form an operating handle, whereby the said arms and the operative connections are located at the same side of the oven and in substantially the same vertical plane.

2. The combination With an oven, of a burner therein, a gas controlling valve for the burner outside of and located at one side of the oven, the oven having an outlet opening at its top and an inlet opening at its bottom, pivoted dampers for the said openings having their pivots extended to the same side of the oven as the gas valve, and an operating member composed of a plate pivoted to the same side of the oven as the gas valve and extending in a vertical plane alongside of the outer side of the oven, the said plate having a plurality of integral Copies of thll patent may be obtained for five cents each, by addressing the laterally extending arms operatively connected respectively With the pivots of the two dampers and With the gas valve, and an operating handle for the plate extending substantially parallel the outer said side of the oven, whereby the said arms and operative connections are located at the same side of the oven and in substantially the same vertical plane.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
