a s ecification.

s invention relates to hydrocarbon burners and has for its object to provide a comparatively simple and thoroughly-efficient. device of this character in which the. oil from a supply reservoir is fed under pressure into a steam chamber and converted into hydrocarbon gas for delivery to the burner.

A further object of the invention 1s to provide a hydrocarbon burner includlng a boiler, operatively connected with a source of water supply, and having asteam chamber sup orted thereon and disposed 1n the path 0 the flame from the burner, the steam from the boiler being discharged into said chamber at a oint' above the intake of theifuel pipe W ereby to 'volatil 1ze' the oil and prevent the surplus 011 or drippings from entering the boller. D

A-further object is to provide an 011 pan disposed beneath the burner and fed from the' fuel supply pipe, said pan forming, in efiect, a pilot burner. and serving to automatically light the main burner 1n case the supply of gas to the mam burner 1s interrupted or suddenly cut-01f and then permittin to flow again.

further objectis to provide a burner which will produce a maximum amount of heat with little if any'smoke or objectionable odor.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

Other and incidental objects will appear as the description proceeds. In the drawings wherein'I have illustrated the preferred embodiment of the invention, and wherein similar reference characters designate corresponding parts throughout the several views: a I

Corresponding and like parts are re ferred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved hydrocarbon burner form-- ing the subject-matter of the present inventlon comprlses a fiat substantially rectangular boiler 5, hollow inthe center, as indicated at 6, and including side members 7 and end members 8, said -members being preferably square in cross-section, as best shown in Fig. 1 of the drawings. 1 Disposed abovethe boiler 5 and preferably formed integral therewith is a tubular member 9 which extends longitudinally of the boiler directly above the opening 6 and is preferably centered With respect thereto, said tubular member having its opposite ends curved or rounded at 10 and its interior unobstructed to form a steam chamber 11. One end of the tubular member 9 is provided with a nipple 12 in which is seated the adjacent, end of a fuel pipe 13, the opposite end of the fuel pipe 13 being spaced longitudinally from the adjacent wall of the steam chamber to form a mixing chamber 14. Connected with the outer end of the pipe 13 at the nipple 12 is a fuel supplypipe 15 which extends Within an oil tank or reservoir 16, the quantity of oil fed into the steam generator being controlled by a valve 17. Extending transversely across one of the end members 8 of the boiler is a partition 18 and communicating with the interior of the boiler on one side of the partition is a Water supply pipe 19 extending to a supply tank or reservoir 20, there being a valve 21, similar I in construction to the valve 17, disposed above the tank 20 and by means of which the quantity of water fed to the boiler may be controlled at will. The tanks 16 and 20 are connected by a pipe 22 from which extends a central pipe 23 leading to an. air pump, not shown, whereby the fuel. and water may be fed to the boiler at all times "under pressure. A suitable gage 24 is inserted in one of the tanks, preferably the oil tank 16 for determlnmg the exact pressure of the airwithin said tanks.

The am from the boiler is fed into-thechamber 11 through a 'short "pi e or conductor 25 which is curved to con cm to the Ecurvature of the ad'acent end'wall of 1 top of the steam chamber directly above the.

fuel pipe 13 whereby the fuel the tubular member and discharges at the carbon gas for delivery to the burner, indi- "cated at 26. By having the mouth of the conductor arranged above the pipe 13 liability of any surplus oil or drlppings is effectually eliminate The burner 26 is disposed in a horizontal plane and is connected with the steam chamber 11 at a point" spaced from and directly in advance of the pipe-1'3 through,

adjacent end of the fuel the medium of a pipe sec on 27 threaded intoan opening 28 in the tubular member 9,

as shown. Disposed beneath the boiler and preferably extending the entire length thereof is an oil pan 29' adapted to contain cmders, slag, broken fire-brick or other refractory material and intov which oil is fed through a branch'pipe'30 connected with the 1 main fuel supply pi e 15, there being a 'valve 31 in the brane pipe 30-for controlling the quantity of oil deliveredto the pan 29 at will. The flame from the oil pan 29 not only serves as an additional means for heating the boiler but also forms, in effect, a pilot burner for automatically lighting the gas 'at the main burner 26 should the flow of gas to the mainburner 26 be sud-' denly interrupted or cut-ofl and then permitted to flow again. The tubular member 46 9 being disposed above the opening 6 in the boiler is directly in the path of the flame from the,..burner so that the steam chamber is maintained at the desired temperature at all times and inasmuch as the oil pipe 13 is disposed within the steam chamber, the tubular member 9 acts as, 'a housing therefor and prevents the flame from coming in direct contact therewith.

In operation the valve 31 is partially opened so as to permit a, small quantity of oil to drip into the pan 29 which oil'is then lighted, after which the valve 21 is opened and the water permitted to circulate within the boiler. The heat from the oil pan will enerate steam in the boiler 5 which steam ows upwardly through the conductor 25 and is discharged into the chamber v1'1 around the fuel pipe 13. The valve 17 is then adj usted-to permit the desired quantity of oil to flow throu h the steam chamber 11. s the Oll passesthrough the pipe 13 it becomes heated and is volatllized and as the gas issues from the end of the pipe 13 it commingles with the steam in the mixingchamber and is converted into hydrocarbon gas, which gas passes through pipe 15 into the ing - from the pipe 13 flowlng back into the boiler Y 15 I cause the steam to swee generate steam 'in' the boiler,

the ipe 27 a; the busier 2e and 'is i aaea by t e flame from the pan 29. As the burner 26 is dis from said burner will be 'directly'lon 'tudiml of the boiler and not only heat t e side and and members of the boiler, but the heat from the flamewill pass upwardly throu h the central opening 6 and superheat t e d in a. horlzontal plane the flame any oilthrough the pipe 13 until fast .asit enters the mixing chamber and the oil vapor through the pipe 27 to the ame. By avoidmg the use of the pipe 13 and burner 26 to the danger of oil carbonizing or caking in the pipe 13 before being surround and heated by steam, 1s reduced to a minimum and there 1s I no danger of any sediment or deposits forming in said 'ipe or in the mixing chamber 14 that will ave to be removed by the steam when it is finally generated and becomes active.

While the boiler 7 is shown substantially rectangular in shape it will, of course, be understood that the boiler may be of any other desired shape and that the tubular member 9 instead-of being formed integral with the boller maybe made separately and subsequently bolted or otherwlse attached to the boiler iffound desirable or necessary in the actual practice of the invention. In-

asmuch as the oil passing through the pipe 13 is constantly heated by the steam inthe chamber 11, said oil will not have a tendency to cake or stick within the pipe 13 so as'to leavedeposits of carbon therein and thus cause the burner to smoke and give off a disagreeable odor. It will here be noted that owing to the curvature of the conductor 25, the steam passing there'through will strike the upper wall of the tubular member 9 and thence be deflected downwardly around the fuel pipe 13 and forwardly in the direction of the mixing chamber 1 so that not only' is the fuel in the pipe 18 "maintained at the proper temperature, but a thorough. intermixing of the steam and oil gas is effected in the mixing chamber 14 rior to its delivery to the main burner. he device is extremely simple in construction and may be manufactured and placed on the coilnlparatively smal cost.
