GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 464,295, dated December 1, 1891.

Application tiled July 14, 1891.

To all whom, t may concern.:

Be it known that I, VARREN L. CORT, of Flatbush, Kings county, and State of New York, have invented a new and useful Improvement in Gas-Stoves, of which the following is a specification.

My invention refers more particularly to gas-stoves used for heat-ing sad-irons, and relates to the burnerof the stove and to the supply-pipe by which the gas enters the latter.

In the drawings, Figure Lis a front elevation of the stove, showing my improvement on the same. Fig. 2 is a sectional side elevation. Fig. 3 is an enlarged sectional side view of the stop-cock and air-chamber and parts of the stove. Fig. 4 is a plan View of the lower part of the stove, showing the burners; and Fig. 5 is a sectional View ofV one of the burners through the line n: zr, Fig. 4.

Heretofore in the use of gas-stoves muc trouble has been caused by the stop-cock or valve which regulates the flow of the gas, and which is situated immediately outside of the frame of the stove, becoming heated and thus expanded, thereby interfering with the perfect action of the parts and frequently causing the stop-cock to stick, so as to be turned with difficulty. As will be seen in the construction shown in the drawings, the stop-cock e and its plug-casing e and the mixing-chamber c, in which the air and gas are mingled, are situated immediately in front and just outside of the stove, and when the latter is in operation the radiated heat from the burning gas and from the heated sad-iron, as well as the direct heat from contact with the burner, causes these parts to become very much heated. To prevent this and keep the stopcock and its adjacent parts cool, I employ a guard or detlector a. This, as shown in the drawings, consists of a strip of metal, preferably zinc or a metal having a low heat-conducting power, which is attached to the stove so as to project outward and encircle the miX-' ing-chamber and stop-cock, and thus prevent the rays of heat from striking these parts. In the particular construction and arrangement of the parts shown in the drawings the pipe or tube b, which communicates with the burner, is provided with a flange b', which Iits against the perforated lip or skirt Z of the main frame and is bolted through to the flange Serial No. 399,506. (No model.)

c of the mixing-chamber c on the outside of the main frame. Between thevlip or skirt lof the main frame and the iiange c of'the mixing-chamber is placed the liange a of the guard or defiector a in such a manner thatthe main part of the defiector projects outward over the mixing-chamber and stop-cock, and the whole is secured by the bolts d, passing through the flanges o', c', and band through the skirt or lip l. The several parts are thus securely fastened in position, so that the gas entering through the stop-cock and mingling with the air in the mixing-chamber entering through the holes c2 passes through the perforation in the skirt or lip Z of the frame and thence through the pipe or tubeb to theburner, and the deflector ct surrounds the mixingchamber and stop-cock and its plug-casing e and protects the same from the heat radiated from the burning gas and also from the mass of the heated sad-iron above. To protect these parts from the direct heat of the burner transmitted by the tube or pipe b, communicating with the burner, I interpose between the lip or skirt Z ofthe frame and the flange ct of the detlector awasher f, of asbestus or similar material, and place a similar washer h between the flanges o of the deiiector and c of the mixing-chamber. These washers effectually prevent all heat from passing from the pipe b to the mixing-chamber .and the stop-cock beyond. It may not be necessary under all circumstances to use both washers f and h; but either one may be used singly, as desired. As will thus be seen, the detlector o, surrounding, as it does, the stopcock and other parts and having the asbestus rings or washers f and h, etfectually protects those part-s from the radiated or deflected heat from the'gas-ame and also from the direct heat from the burner.

I do not wish to limit myself to this particular manner of securing the detlector, as it may be connected with the stove in a variety of ways, so as to be interposed between the parts to be protected and the heat from the iiame and the burner.

The burners are composed of two annular plates m m of metal, havin g'hori'zontal iian ges n n and arranged to it over each other, so as to inclose an interior space 0. The flanges n and n are clamped or fastened together by IOO bolts or screws n2, and between the two fianges 1s placed suitable packing, so as to form aperfectly-tight joint that will prevent the escape of the gas. The plates m and m extend u pwardly and inwardly, the outer plate m having a greater inclination than the innerplate, so that at the top the two plates approach close to each other, leaving only a narrow opening 0 between them, through which thergas passes and where it is ignited. The plates are oblong in form, so that when put together they forrn an oblong burner, as shown in Fig. 4, having a continuous opening or orifice o', and thus producing a continuous oblong llame, which heats every part of the sad-iron. The mingled gas and air enters the interior space 0 through the pipe Z), as described above.

In a burner formed ot' annular plates, as above described, there are no overhanging parts in the interior space to interfere with the free passage of the gas; but the gas or mingled air and gas passes rapidly through the interior space and out at the top, and, moreover, by reason of the annular plates inclinlng toward the top a large burner-chamber is obtained, which, with the i'nclining sides and narrow opening, concentrates the gas at the point where it is ignited, thus intensifying the heat. Furthermore, theinclination of the plates m and m allows of varyingthe size of the orifice or opening o', so as to regulate the size of the flame, as by increasing the distance between the flanges fn and 'n' by the packing the opening o may be increased at pleasure.

l. In a gas-stove, the detlector a, arranged and adapted to surround the stop-cock and its casing and connected tothe frame of the stove with the vrasherf, substantially as described.

2. In a gas-stove, the combination, with the main frame having an opening in the skirt or lip, of the tube b, having the ilange Z9', the mixing-chamber c, provided with the flange c', and the deector cl., substantially as described.

3. In a gas-stove, in combination, the burner formed by the annular plates m m', having` the Vcontinuous orifice o', tube b, provided with the flange b', bolted to the'inside of the perforated lip Z, mixing-chamber c, provided with flange c', bolted to the outside of the perforated lip, stop-cock e, casing e', and detlector (t, arranged to project outward from the stove and surround the chamber c and stop-cock e, substantially as described.
