CHARLES A. HAMMEL, OF LOS ANGELES, CALIFORNIA.

HYDROCARBON-BURNER.

Application nled October 9, 1916. Serial No. 124,834.

To all 'whom it may concern.'

Be it known that I, CHARLES A. HAMMi-n., a citizen of the United States of America, residing at Los Angeles, in the county of Los Angeles, State of California, have invented' new and useful Improvements in Hydrocarbon-Burners, of which the followin is a specification. y

is invention relates to that class of hydrocarbon burners in which oil is moved through a burner head by means of steam or air under premure and commingled therewith, and pertains es ecially to improvements in my invention ydrocarbon burners disclosed in United States Letters Patent 748,862, January 5th, 1904.

The objects of my invention are to improve the construction, whereby the burner may be quickly reassembled, after having been taken apart for any purpose; and to provide a construction whereby the-dura ilit 4of theburner is increased.

' I ave found that in reassembling burners of the ty e.disclosed in the Letters Patent above refldrred to, the mechanics often fail to exactly aline the several parts, thereby causing incorrect distribution of the oil in the mixing; chamber, with a consequent unbalancing of the llame. Due to the small di' mensions of some of the steam passages -lead-` ing from the e ualizing chamber to the mixchamber, ight displacement will cause umlalancing. `To the endthat correctalinement in asombling may be secured, I have provided means for insuring correct pos1' tion of the parte, with respect to each other.

I have also provided means' for straining the steam to prevent impurities from pass straining the steam and separating therefrom foreign matter and the water of condensation.

I accomplish these objects by means of the embodiment of my invention, illustrated 1n the accompanying drawings, in which:

2 is a central, vertical longitudinal section of the burner head.

Fig. 3 is a view looking upwardly of the upper part of the head.

1g. 4 is a plan view of the base of the head.

Fig. 5 is a front view of the upper rear portion of the head. 0 Referring more particularly-to the drawing, the burner head is comprised of a base 6 upon which is mounted a rear part 7 and a tip part 8.

Base 6 is provided with a lon 'tudinally extendin steam inlet bore 9 t readed at the end or receiving a steam pipe. A port 10 communicates with said bore and opens through the top of said base. The forward end o the bore is reduced in' diameter and a condensation ort 11 communicates with the upper part o the base at the forward end. A recess is formed in the top face ofthe base for the reception of a. wear plate 12. Below the wear plate a. recess 13 is countersunk. the latter flaring laterally from the 'condensationthport 11 and being of relatively small The upper rear part 7 of the head has an equalizing chamber 14 foi-med in the lower face. T he chamber is formed with an inclined wall 16' at the forward end,'thereby forming extensionsy 15 and 17. Leading from the'equalizii'i chamber are threeducts e outerV ducts .15 and 17 communicate with the extensions 15' and 17', converge and are high and narrowg' they disehar steam-on lines which will intersect each ot er in 'the mixing chamber and thereby thoroughly mix and commingle steam and oil. A cylindrical strainer 18 of perforate material is placed in equalzing chamber 14` above port 10. Above the equalizing chamber and extending 'longitudinally of the head orton 7, is a'n oil supply inlet 19 .suitably threaded at the end to receive an oil supply pipe. An oil duct 20 of 'reduced diameter communicates with inlet 19 'and is4 directed downwardly toward the lower Fface to a point above steam duct 16 and between ducts 15 and 17. Fixed to the head o ion 7 is a dowel pin 21, which projects i tly from the front face and is inclined thereto.

The tip part 8 is provided with amixing chamber 22 which flares outwardl j' Its smaller dimension is equal to the istance between the outenwall of ducts 15 and 17. When in position, the rear of chamber 22 should exactly register with ducts l5 and il', so that the side walls exactlyr register with the steam ducts. A Haring passage is therelfy formed in which the steam and oil is mixed, and in which there are no projections or recesses to unbalance the distribution of steam and oil in the chamber. Such construction I have found necessary for an cllicient working of the head. Channels are formed at the upper portion of the equalizing chamber for the reception of wear plate 23. A recess is formed on the rear base of the tip 8 to receive the projecting dowel pin 2l. To hold wear plate 23 in position, a set-screw 2l is provided.

fr T he head is Iassembled by mounting head part 7 upon base 6 and securing it thereto by means of bolts 25. Wear plate 12 is then placed in position, and tip 8 placed on basf` G. Bolts 26 are then tightened up securing tip 8 to the base. As the bolts 26 are tightened the tip is alined with respect to the base, so that the side Walls of the mixingchamber and ducts 15 and 17 exactly regster.- This is a very important feature of my invention. I have found that unsatisfactory `and inefficient operation of the old type of burner without the dowel pin, after having been taken apart for repairing or cleaning, was due to a failure of the mechanic to properly align the tip 8 and rear portion 7 in reassembling the burner. A displacement of one sixty-fourth of an inch from true alinement will materially decrease the efficiency of the burner and result in unsatisfactory operation. With my improvement, it is impossible for the burner to be reassembled without perfect alinement of the steam ducts and mixing chamber.

Water of condensation enters port 9 with the steam and collects in the well formed below port 10, and is forced forwardly through the condensation port 11, spread in recess 13, and discharged out at the forward end of the head below the ame. Any boiler scale, dirt or foreign matter in the steam is caught by strainer 18, and is prevented from passing out through the mixing chamber. In this way the life of wear plates 12 and 23 is increased, and the 1liability of clogging decreased. These factors allmaterially add to the eliciency and satisfactory operation of the burner head. On disassembling the burner for cleaning and renewal, perfect alinement in reassembling is assured and therefore. ellirfent and satisfactory opera- 'liat l claim is: l. A burner comprising a base having a steam inlet. a lateral portion communicating.r therewith. :mil a condensation port at the 0nd thereof; :i part h:|\ ing a steam ellnaliy.- ing' chumiu-r. steam ilnrl communicating i thercwiiii. and an oil duri: :i `strainer disposed in said rqualiaing chamber to catch foreign matter entering said lateral port; a tip having a mixing chamber communicating with said steam and oil ducts; and a dowel pin disposed between said part and said tip insuring alinement of said ducts and said mixing chamber.
