To all whom it 'nia/y concern.'

Be it known thatl, Ronnnr V. HOFFMAN,

a citizen of the United States, residing at Brenham, in the countjyof Washington and State of Texas, have invented a new and useful l-lydrocarbon-Burner, of which the following is a specification. This inviuition relates to hydrocarbon burnelsfanll more particularly to burners of that tvpnused fordomestic purposes, such as cooking and heating.

One of tlie\principal objects of the inventionis to provide a simple but effective systein of a novel nature that can be readily installed, and is easily understood and controlled.

A further object is to provide a burner in which steam is employed, to provide a steam generator that is automatic in its character, is heated by the burner, and yet protected from injurious action.\by thc flames therefrom, and will not require constant attention and regulation in order that the steam supplied to 'the burner may be properly proportioned to the fuel delivered.v

The preferred forni of construction is illustrated in the accompanying drawings, wherelIi t Figure l is a front elevation of the com plete apparatus showing' the saine applied to an ordinary kitchen range. Fig. 2 is a sectional view through 4the 'lire box showing the burner and associated parts. 3 is a horizontal sectional view showing said parts in top plan. Figl is an end view of the mechanism. Fig. 5 is a front elevation of the target andmui'ller. Fig. 6 is an end View of the same. lvlFig. 7 is a detail sectional View on the line 7.#7 oli' Fig. 5. Fig. 8 is a sectional view through the steam generator and regulating valve. Fig. 9 is a longitudinal sectional view through the burner. Fig. 10 Fig. 1l is a detail View of the spider located within the burner, and showing the inner nozzle therein.

Similar reference ,numerals designate corresponding parts in all the figures of the drawings. y

1n 4the embodiment disclosed, a burner is employed, comprising an outer casing 12, having an upstanding nipple 13 at one end,

and having a nozzle 14 threaded into itsother `end, said nozzle also constituting a clamp for a spider l5 that removably ttcd into the end of the casingin which the noztiguous to the front end of theeasing. The

rear end of the casing 12 is provided with a plug 19, cari' Ying a stuffing box 20, through which slidab y extends a cleaning rod 21, having an exposed knob 22. This cleaningr rod 22 extends longitudinally through the inner nozzle 16, and is movable through the discharge end thereof and into the discharge orifice of the nozzle 111.

The burner, as shown in Figs. 1-4 inclusive, is preferably located over the hearth 22*l of a stove, with the nozzle 14 projecting into the fire box 23 of said stove, and arranged within said lire' box in line with the discharge end of the burner, and disposed transversely thereof, is a steam generator 24. The steam generator, as clearly shown in Figs. 2 and 8, is in the form of a boxing, set at an inclination, the top and bottom walls being inclined, the end walls being preferably vertical. A steam conduit 25 extends from' the upper end of the generator 2-1, and is connected to the nipple 18 of the steam eonductingchannel 17 of' the burner. lnterposed between the steam generator24 and the discharge nozzle 14 is a target plate 26 that is clamped to the steam generator by clip bolts 27 that pass through said plate and surround the generator, thereby supporting the latter in its inclined. position. The front face of the target plate 26 that is opposed to the discharge nozzle 14 of the burner, is provided with outstanding mulller walls 2S disposed in spaced relation, and on opposite sides to the longitudinal axis of the burner, these niu'liler walls being oppositely and inwardly curved, as shown, and having inwardly extending flanges 29 ongtheirouter edges. The walls 2S are secure/'l to the plate in any suitable manner, as for instance, by brackets 30.

An oil reservoir 31, located at any desired place, either inside or outside the house, has a pipe 32 extending from its upper end and connected to the nipple 13 of the burner. Thus the interior of the outer casing 12 contained at all tinies.

stitutes an oil channel within which extends than the reservoir 31, and burner has water conduit 37 connected to its bottoni, said water conduit also being connected to the lower portion of the oil reservoir 31. A controlling valve 38 is located in the pipe 37.

Leading troni the pipe 37 is another pi )e that is connected to the lower end of the steam-generator 24, and has a controllingvalve 4() arranged therein. A casing 4l is also located in the pipe 39, and arranged therein, is a iloat 42 having a link connection l43 with one arm ot a bell crank 44, the other "arn'i of this bell crank lever being connected to a valve 45 'that controls the inlet of water to the casing 4l through the pipe 39. A steam ipe 46, connected to the upper yend of the inc ined generator 24, also has a connection with the upper end el the casing 41.

The valves 3S and 4() may be left open at all times, except during the filling of the oil or hydrocarbon reservoir 31, in which case, the valve 3S must be closed. It will be evident that if, the reservoir 31 is filled with oil or other hydrocarbon, and the reservoir 36 is filled with water, said water, if the pipes 37 and 39 are open, will passinto the lower portion olfA the reservoir 31, and through. the pipe 39 into the steam generator 24. 'l he level of the water in the latter is regulated by the float 42, but when said water reaches a predetermined level, the oat 42 will close the valve. 45. As soon as the level falls, the iloat '42 will also fall, thereby opening the valve 45, and rpermitting the inilow oi' water until the predetermined level is again reached. Thus, the said levell is automatically mainln starting the burner, the valve 31% is opened, and thus the water 'from the reservoir 3G will displace the oil in the r servoir 3l, and vtorce it through the pipe 32 to the burner. A. preliminary heating of the generator 24 is ell'ected by any suital'ile means, and 'as soon as steam is generated, the same will pass through the pipe 2.5, and the inner nozzle 16, thus drawing the oil withv it, and expelling it through the nozzle l5. li therefore, the expelled vapor is ignited., it will burn freely, and the llames will be projected against the target 26. Experience has demonstrated that the walls 2H will praetically eliminate the sound ordinarily caused bythe combustion ol the oil and steam, and moreover the target prevents the llames vfrom impinging against the generator 24, and

` thus injuring the same.

ltwill be evident ,that as soon as thel burner is in operation, the entire apparatus will operate automatically,"lior as fast as the water in the generator is changed into steam, lresh water will be supplied to the lower end of the generator. 'lhis is an exceedingly irnportant 'feature of' the invention, for in the inclined generator, the cold water is introduced at the bottom, and as the temperature rises, it will gradually rise to the top until turned into steam. i

From the foregoing, it is thought that the construction, operation, and many advan# tages of the herein described invention-will be apparentoto those skilled in the art, without further description, and it, will be understood that various changes in the size, shape,

proportion, and minorl'details of construc-V tion, may be resorted to without departing from the s )irit or sacrificing any of the advantages oi the invention.
