Specification of Letters Patent.

Patented Aug.. 1?, MM5.

Application'led February 25, 1913. Serial No. 750,511.v

To all whom it may concern zen of thenited States, residing at Los Angeles, inthe county of Los Angeles and State of California, have invented certain new and useful Improvements in Oil-Burners, of which the following is a specification.

This invention relates to improvements 1n oil burners, and particularly to such as are adaptedrfor use in boiler or other furnaces.

It is an object of the invention to provide a burner which may be used with merely a gravity feed of oil suiiicient to cause the same to iiow through the pipesto the burner.

It is a further object of the invention to provide a burner having a nozzle capable of delivering steam in sheet form and also de livering oil thereto so as to be effectively atomized exteriorly of the nozzle.

It is a still further object of the invention to provide an oil burner with an atomizing nozzle which is capable of being swung to one side or to the other for centering the flame or directing it to'any part of a fire box.

In the accompanying drawing, Figure 1 is a side elevation of the improved burner, the oil and steam feed pipes thereforalso being shown. Fig. 2 is a central vertical longitudinal sectional view through the burner proper. Fig. 3 is a detail sectional view upon the line 3 3 of Fig. 2. Fig. i is a perspective view of the adjustable nozzle member of the burner. Fig. 5 is a detail view showing the burner in top plan view, and showing that the direction of the flame may be altered.

The details and features of the invention will now be more particularly described, reference being had'to the drawing, in which 5 lindicates an oil pipe and 6 a steam pipe connected with a burner 7. The pipes 5 and 6 are properly connected in any desired manner with oil and steam supply pipes S and 9 respectively, and a by-pass 10 is usually interposed in the piping and controlled by a valve 11 so that steam may be passed through the oil pipe 5 when desired for cleaning the oil delivering portion of the burner.

Y The burner 7 is formed with an oil passage 12 and a steam passage 13 which assages are adapted to be connected to the oil and steam pipes 5 and 6 respectively. The delivery end of the burner is formed with enlarged head portions 14 and 15, having outlet openings 16 and 17 for delivering the materials to a movable nozzle 1S. The nozzle 18 is formed with a hollow body portion having a central partition 19 which divides the oil receiving chamber of the nozzle from the steam receiving chamber. An oil delivering slot 2O is formedv in the walls of the burner 1S just above the partition 19, and a steam delivering slot 21 is provided in said burner immediately below the said partition 19. The latter slot 2l may be made very narrow so as to spread the steam into a thin broad sheet. The slot 20 is preferably made wider than the 'slot 21 so as to permit of a free delivery of the oil under the action of gravity as it flows upon the sheet of steam. The slots 20 and 21 preferably extend about half way around the nozzle 18 as clearly indicated in Fig. 3 of the drawing. An important feature of the nozzle structure is the beveling of the delivery edge of said partition 19 as shown at 22. The use of this beveled edge 22 is found to cause the oil to flow at once into the at sheet of steam, and to be immediately taken up by said steam, which would not be the case if the partition were not beveled as shown.` The partition 19 is also provided with oppositely extending bosses 23 and 24 which are centrally bored to receive the inner ends of pivot bolts and 26. The said pivotrbolts usually cap screws extend through the central portions of theenlarged heads 14 and 15. The outlets 16 and 17 are of larger diameter than the said pivot bolts so that the oil and steam may iiow around the same to the nozzle without obstruction. It is important for keeping the nozzle clean that the bosses have inclined walls as shown in Fig. 2, and that the spaces between them and the outer walls of the nozzle at their bases be of less size than the spaces at their outer ends. The nozzle 18 is provided with one or more arms 27 and 28 by which it may be moved upon the pivot bolts. The flame may thus be directed to one pointer another in the fire box of a furnace as indicated in dotted lines in Fig. 5.

In use the burner is allowed to extend well into the fire box of a furnace, the pipes 5 and 6 being of sufficient length to reach the desired distance into the combustion chamber. rlhe steam is fed through the pipes 6 and 9 at the desired pressure. Oil is then permitted to flow through the pipe 5 and fall upon the broad sheet of dry steam es caping from the nozzle 18. The converg- Ying Vshape of the spaces around the bosses 23 and 21 is found in use to prevent the collection of foreign substances, dirt or oil,

and cause the burner to be lept absolutely clean. The.solid partition 19 prevents any escape of steam into the oil side of the burner as 'would happen if 'a pivot boltV passed through it, which is also an important feature of the structure. The beveled edge o f the partition 19 leads the oil into thefan shaped sheet of steam so as to be evenly Vand thoroughly atomized thereby and to produce perfect combustion in the furnace.

The nozzle 18 may be turned by tappingV either one of the projections 27 or 2S with a poker or other instrument after the burner yhas been lighted, so as to either center the liame perfectly within the` combustion chamber or to direct it to one side or other of the fire box as required.l

The use of cap bolts for pivotally holding the nozzle, obviates the difliculties arisingV from the use of a pivot bolt that would have to pass through the partition or floor 19, since such a pivot bolt will become loose -with usage and allow steam to pass around it 'into the oil side of the burner. This interferes with a proper flow of the oil and the presence of moisture causes an accumulation of dirt in the oil side of said burner.

What is claimed is: Y 1. A furnace burner having a fuel and spraying agent supply means, comprising a nozzle mechanism adapted to be supported by saidmeans in a combustion chamber, and a delivery member pivotally mounted in said nozzle Vmechanism and having outlet ports for fuel and a spraying agent, an inclined surface being arranged between said ports to properly spread fuel on the spraying A the oil and steam, the walls of said channels being provided with outlet slots extending partially around the nozzle,'and'a beveled partition between said outlets. I 3. Anoil burne'rhaving a body portion provided with oil'and steam ducts therein, said Vbody portion being` adapted' to be YVmounted within a combustionrchamber, aY

Vnozzle pivotally mounted between the outlets of the ducts in said bodyportion and hav-V ing dischargeopenings for spraying ma-V terials, and radially projecting arms on said nozzle adapted to bestruckV or engaged by a poker whereby the nozzle may be turned or adjusted to throw theflame in the right direction without putting out the fire.

Ll. 'An oil burner comprising a body; portion having oil and steam Lducts therein, a

nozzle pivoted between the outlets of said 7() ducts, pivot pins centrally engaging said nozzle, saidnozzle having channels extending around said pivots and formed with dis` charge openings, anda partition havinga curved beveled edge arranged between said discharge openings for, properly commingling the said steam and oil ina radiating flame. f

5. An oil burner having passages for deliveringv steam` and oil to aV ame, a hollow nozzle mounted between the outlet openings of said passages, said nozzle having a' central partition, bosses projecting from said partition, and having apertured recesses,

and pivot pins carried by the burner and engaging said apertured bosses for pivotally holding the nozzle in place.

' G. An oil burner comprising a casinghaving oil and steam passages therein, a nozzle pivotally mounted between the delivery `9@ outlets of said burner, saidlnozzle having oppositely extending-bosses and a partition forming steam and oilchamberswithin the nozzle, tli'ewalls of said bosses bemgtapered outwardly toward the bases and the burner being provided with outlet slots opposite the bases of` said bosses, whereby materials passing through the chambers in the nozzle will be kept cleaned of all deposits. Y

In testimony whereof, I have here-unto set my hand, in presence of two witnesses. Y Y JOHN sonnes.
