GAS-BURNING APPLIANCE FOR STOVE-OVENS.

No. 866,143. Specification of Letters Patent.

Application tiled August 8,1906. Serial No. 329.674.

Patented Sept. 17', 1907.

To all whom it may concern:

Be it known that I, WILLIAM H. KIRK, a citizen oi the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Gas- Burning Appliances for Stove-Ovens; and I do hereby 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.

My invention has for its object to provide an improved gas burning device for the ovens of ordinary wood or coal burning cooking stoves or ranges, whereby gas may be used as fuel to bake within such ovens, and to the above ends the invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

The invention applied to the oven of an ordinary cook stove or range is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views.

Referring to the drawings, Figure l. is a view partly in side elevation and partly in vertical section, showing the oven and surrounding flame chamber ol' an `ordinary cooking stove or range. Fig. 2 vis a view partly in plan and partly in horizontal section on the line x2 x2 of Fig. l, some parts being broken away; and Fig. 8 is a bottom plan view showing the gas-burning appliance in bottom plan view and removed from the stove.

The numeral l indicates the body of an ordinary cooking stove or range, the numeral 2 indicates the oven thereof, and the numeral 3 indicates the flame chamber which surrounds the said oven.

In the preferred application of the improved gas depending legs 14. that rest directly upon the bottom of the oven by nutted bolts lln passed through said plate l1 and a strip llh underlying said grate 13, and the grate 13 is, in turn, directly secured to the said twyer pipes by wires l5. To prevent the central portion of the deflecting sheet of asbestos 1G is interposed between the grate 13 and the under surface of the said plate ll, as shown in Figs. l and 3. It will thus be seen that the twyer' pipes l0, the deflecting plate ll and the grate 13 are so connected that they may be together removed from the stove and together applied within the oven thereof. The connection between the inner end oi the sleeve 4 and the sleeve receiving socket or coupling sleeve 8 is made by moving the latter toward the right with renected from the sleeve 4 by a reverse movement of the said twyer pipes. To prevent external separation oi the said parts 4 and 8 when the burner is attached, a stop clip or arm 17 is adjustably secured to the left hand edge of the detlecting plate ll, as shown, by means of a short nutted bolt 18 that works through a slot 19 in said clip and is passed through the said deiiecting plate. A suitable valve (not shown) should be applied in the pipe 7 for turning on and shutting off the supply of gas,

When the burner attachment is applied and is in use, the burning products of combustion `from the twyer pipes affords an upward passage into the oven only in the vicinity of the marginal portions of the deflecting plate l1, to-wit, either through the perforations l2 or around the edges oi said plate, and thus all articles placed on the intermediate portion of the defieeting plate are protected to the extent that they will not be burned when the stove is properly regulated. A very considerable amount of heat will, however, be radiated upward through the central portion of the said defiecting plate.

extended through perlorations in one of the walls ofthe oven and in the adjacent wall of the stove, and is secured in position by nuts 5, as best shown in Fig. l. To the outer end of the sleeve 4 is attached an air regulating damper 6 of the usual or any suitable construction, and into this damper which leads from any suitable source of gas supply under pressure. The inner end of the sleeve 4 is slightly tapered to adapt it to be inserted into a correspondingly tapered seat formed in a coupling sleeve 8.

suiiicient ordinary stove into the surrounding flame chamber or draft passage to carry ofi the products ot combustion. Oi course, if desired a draft flue might be provided lor that purpose.

The device described is of small cost and in practice has been found highly efficient for the piu-poses had in view. Furthermore, when'desired the gas burning appliance may be quickly detached and removed from the stove, and when desired may be very quickly applied thereto.

What I claim is:

A heat deliecting plate ll overlies the twyer pipes l0 and extends nearly but not quite over the entire lower surface of the oven and con range, of a gas burningl appliance for the oven tl1ereof,` comprising a gas conducting` sleeve extended through thewalls of the oven and the adjacent wall of the stove, a twyer detachabiy coupled to the inner end of said sleeve,

to its four edges. As shown, the deflecting cured to a skeleton frame work or grate 13 plate is sewhich has plate ll from becoming too hot, a

l. The combination with an ordinary cooking stove ordefiecting plate overlying said twyer Walls of and a rectangular and spaced at its four edges apart from the four the oven, substantially as described. l

2. The combination with an ordinary cooking stove or range, of a gas burning appliance for the oven thereof, comprising a gas conducting sleeve extending through one of the Walls of said oven and the adjacent wall of the stove and having a tapered inner end, a pair of connected twyer pipes having a socket fitting the tapered inner end of said sleeve, and a deecting plate overlying said twyer pipes, substantially as described.

3. 'lhe combination with an ordinary cooking stove or range, of a gas burning appliance for the oven thereof, comprising a sleeve extending through one Wall of the presence WILLIAM H. KIRK. Witnesses:
