OIL BURNER FOR STOVES.

Application filed July 26, 1.921. Serial No. 48?,714.

To all whom it may concern Be it known that 1, WILLIAM H. 'BOZARTH,

the inner side of thejbu'rner; v

, Fig; 3-is a view similar to Fig. 2 'wi'tli the 7 base and oven heat-ingburner removed. i

resident of Vineland, inthe county of Cumberla n'd and State of New Jersey, citizen of the United States, have invented certain new and useful Improvements in Gil Burners for Stoves, of which the following is a specification.

My present invention relates to oil burners for stoves, and particularly to a burner structure to be fitted in the standard type of kitchen range or cook stove.

An object is to provide a burner which can be readily fitted in place in astove and which will heat the stove top and-also the oven after the manner intended in the use of coal, wood, or like fuel.

Another main object is to provide a burner and generator. structure which are so associated that the gas is discharged to a central manifold from which the gas passes to the two stove burners and to a burner supplying heat to the generator.

A further object is to provide a burner of this type which is so constructed that oil supplied to the burner is converted into gas which gas supplies'the flame.

A still further object is to so construct the parts that the supply of gas can be directed in full volume to either the burner heating the stove topfor the oven burner, or these burners can be operated together.

Another object is to provide for the supply of steam-with the gas to thus give a better mixture and guard against the formation of carbon, and to arrange for generation of the steam by utilizing heat resultant from the operation of the burner.

Yet another object lies in providing for a proper supply of steam andoil, controlled by a single valve, during the operation of the burner, and in arranging for the supply of oil alone for starting the burner.

Yet a further object resides in providing a gas discharge from the generatorv so arranged that any particles of extraneous matter will be held back and danger of clogging is thus obviated.

With these and other objects in view, which will be apparent from the drawing, specification and claims, this invention includes certain novel features of construction and combinations ofparts which will now be set forth.

In the drawings:

l The structure is supported onthe'two base or leg members 1' and 2, the oven heating burner 3' being mounted directly on theleg members and the topfb urner 41: being: carried. which is supported by.

bya gas manifold 5 the l eg'members.

The top burner consists ofthe two 'elo'ri-j;

gated burner sections 5 and 6 wh i'c h have the circular openings and seats 7 formed alone h n; I ength re e ve" e t ted burner d1sCSY8 of refractory material, screens 9 being l tin ed beneath the" was discs, and these discs being setto project above the top of the burner members. I

The oven heating'burner 3 consists of an elongated case having a plurality of op n,

ings "10in which the perforated burner d sc's t 1 1 are seated" after the manner. of the discs 8, screens being also provided beneath the.

discs 11. In use the burner meniber's 3, 5,;

and 6 are filled with gas. anfd'the screensbeg neath the burner discs screen this gas" as it passes to, the burners and at; theisame time prevent the flame from car'ryi rigjbacli to cause backfiring. The burner 3: is preferably made curved on itsouter andtopfedges, and the recesses 10 are so formedthat discs llare disposedat an angle, thisi are rangement being made to directthe flames outwardly at an angleand. to thus heat the oven at. the proper point. i

Between the sections'5. and 6 of. the top- I burner ess enerate t e 2 disposed, this tube. being of thin brass or. other" suit? able material and having a core therein f t ifs to carry the oil. A generating burner 14 is disposed beneath the generator tube 12 and is provided with the longitudinal burner slots 15, a central slot being preferably formed directly beneath the generator tube and a slot being provided on each side of the center so that the flame will strike and curl around or envelop the tube to heat all sides. Wicks 16 are provided for starting the generator.

At its discharge end generator tube 12 has a box 17 secured in place, this box being formed with a depending portion and having a central bafile wall 18 extending down from its top into this depending portion. The gas discharge opening 19 is on the opposite side of the baffle wall 18, and as this opening is extremely fine the volume of gas in box 17 is more or less quiet so that any particles will settle into the lower end where the gas passes beneath baflie wall 18, and thus danger of the discharge opening 19 or the burners being clogged is obviated.

' The gas settling and discharge box is fitted in an opening 20 provided in an air box 21, which air box is open at 22 to the atmosphere. A curved gas supply pipe 23 is connected to open into the air box in line with the gas discharge opening 19 of box The pipe 23 is curved downwardly and inwardly and is connected with the manifold 5 so that gas generated in tube 12 and mixed with air in box 21 is supplied and discharged directly into the manifold.

This manifold, as best shown in Figs. 5 and'7, has branches 24 and 25 which lead to and connect with the two portions 5 and 6 of the top burner 4, a branch'26 which connects with the oven burner 3, and a branch 27 which leads to the generator burner 14. By this arrangement the manifold has connection to supply gas to each of the burners. The generator burner 14 will be kept in full flame continuously during the use of the burner, and any control of the gas supply at this point will be accomplished through manipulation and regulation of the oil supply, however it is desirable that provision be made for directing and varying the flow of gas to the burners 5, 6, and 8, and with this in mind I provide butterfly valves 28, 29, and 30 in the branches 24, 25, and 26. As shown in Fig. 7 these valves are to be set in such a. manner that when valves 28 and 29 are open valve 30 will be closed, and the reverse, an intermediate position being calculated to give a full flow through all of the branches. To accomplish this manipulation of the valves 1 provide operating arms 31, 32, and 33 upon the valve stems, with a push rod 34 connectmasses ed to operate the valves 28 and 29 and a link 35 coupling valve 30 to be moved therewith. it has been found by repeated and exhaustive tests that a butterfly valve gives excellent results in this connection as the operation is single and there is no objection to leakage which will maintain a small flame at the burner when the valve is closed. Other valve structure and operating mechanism might however be used in accomplishing this result. I I

While the box 17 will catch foreign matter, a blow-off valve 36 might be connected in the bottom of the manifold for blowing ofi condensation. Also any type of safetyvalve might be provided in the steam pipe 39 to guard against excessive pressure.

While this burner will operate etficiently and economically upon oil being supplied to the generator, it has been found advantageous to maintain a supply of steam as this accomplishes a better gas mixture and prevents formation of carbon. During the operation of the burner hot gas is supplied to the generator burner 14, and a coil 37 l is arranged within the case of the burner 14 to generate steam. Water is supplied through a pipe 38 to the coil 37, and the steam is discharged through a steam pipe pipe 41 with generator tube 12, and this valve casing has a needle valve 42 controlling the main passage thereof. Oil and steam. branches 43 and 44 communicate with the main passage, opening through the seat of valve 42. Connection is made through an oil pipe 45 from a suitable oil supply, and the steam pipe 39 connects with passage 44. By this arrangement the flow of oil and steam will be simultaneously controlled and the proper proportions will be maintained, it of course being understood that valves can be introduced in pipes 39 and 45, or at other suitable points where adjustments may be desired or necessary.

In starting operation of the burner oil only will be supplied to the generator tube, and for starting this oil may be supplied through a branch 46 leading to the main passage of the valve casing, an oil pipe 47 being connected with the passage, and a needle valve 48 controlling the flow of oil therethrough.

In the use of my improved structure the burner will be fitted in the fire box of an oridnary type of kitchen range or cook stove, with push rod 34 extending through one of the draft slots and pipe 44 run into the burner through any suitable opening. In starting the burner a volatile liquid is poured onto the wicks 16 and when the generator tube 12 is properly heated valve 48 is opened to supply oil from pipe 47. Gas is generated and is supplied to burner 14, and also to burners 3, 5 and 6. As the A valve casing 40 is connected by a heated gas flows into the casing of burner 14 around coil 37 steam is generated therein, and when the proper heat is attained valve 42 is opened and valve 48 is closed. Steam and oil are then supplied through pipe 41 to generator tube 12 and the burner is continued in operation. By manipulation of I push rod 34: the butterfly valves 28 and 29,

as a pair, and valve are shifted as hereinbefore described to give a full supply of gas to either the top or the oven burner, or to leave the passages open to both.

WVhile, in the foregoing, I have described specific embodiments, and have mentioned only certain possible modifications, it will be appreciated that in practice I do not limit myself to such specific details as herein set forth, but may resort to any practical modifications falling within the scope of the invention as defined in the appended claims.
