To all 'Ju/7,0711, 'llt 11m/y con/007%;

Be it known that l, ALLAN C. RUSH, a citi- Zen of the United States, residing in the city of Los Angeles, in the county of Los J-lngeles and titane of `California, have invented certain new and useful improvements in Injector- Burncrs, of which the following is a specification.

This invention relates to positive and elli cient means for ntilizingliquid hydrocarbon as fuel, and particularly to means for thor-- ougllly and completely atomizing said fuel.

rlfhe primary object of the invention is to provide an injector-burner which while extremely useful shall be very positive and eilicient in operation and in which all liability of clogging' or choking the burner by carbonization will be avoided and which shall be simple and cheap in construction and which shall be peculiarly adapted for use with heavy crude hydrocarbon oilsmsuch as, for instance, the heavy crude asphaltuni oils of California.

lo this end the invention consists in the constructions and combinations of parts hereinafter described in detail, but particularly pointed out in the claims.

The invention will be more readily understood by reference to the accompanying' drawings, forininga part of this specification, and in which Figure 1 is a plan view of a burner embodying my invention, the cap of the burner having been removed. lllig. 2 isa longitudinal sectional view el the line ffl X2 of Fig. 1. ldig. 3 is an inverted plan view of the cap of the burner of the style shown in Fig. 2. Fig. a is a side elevation of a burner embodying' iny invention, showing another means of retaining the cap or cover in position. Fig. 5 is an inverted plan view of a modified form of the cap or cover.

ris shown in the drawings, the casing 2 is provided with a chamber 3, and through the center of this chamber extends a pipe or cylindrical casing ll, which may be integral with the casing 2, as shown in the drawings, or may be removablyr secured therein. The rear end of the casing 2 is open to receive the oil pipe 5, and the steam pipe (5 extends through the pipe 5 into connection with the casing or pipe et, the

pipes

6 and 11 forming the stcamway. rlhe casing 2 at its upper or outer end is closed by a suitable top 7, and this top or floor 7 is provided at its center with an opening 8, registering with the way ll of the easing or pipe rlhe openilig Fi is preferably flared outwardly toward its top, as shown, to provide for the expansion of the steam. An annular channel 9 is provided on the top plate Y, as shown, and at the front of the casing 2 this channel extends clear through the top plate i' and into communication with the oil chamber o1' way 3, and forms the oiloutlet l0.

ll represents a spacer-plate adapted to be secured on the top plate Y and provided with a cutaway portion, so that the plate 11 forms, in efect, a segmental ring. 'lhe segmental ring 11 is so positioned on the top plate that this cutaway portion is toward the open oilduct l0,

The easing 2 is provided at its upper end with an annular flange 12, which is flat on its upper face and extends out beyond the annular channel 9. Vllhis flange 12 terminates be low the level of the upper surface of the top plate "i', so that the upper face of the llange 'IQ is slightly lower than the upper face of the plate 7.

i3 represents a member adapted to lit upon the upper end or top of the casing 2. 'lhis member 13 is provided with an annular llange la, corresponding to the llange 12 of the casing?. and adapted 'te rest thereon. The llanges 1Q and 14 are provided with suitable holes through which bolts 15 are adapted to be insorted to hold the member 13 rigidly in place with respect to casing The member 13 is provided with a bead 16, adapted to rest in the annular channel 9.

lily reference to Fig. 3 it is seen that both flange 111 and bead .i6 of the member 13 are cut away at the front of the burner and over the annular oil-outlct 10, and that the niember 13 thus forms, in effect, a segmental ring, the eut-alvay segment of which controls the width of the llame from the burner, and that said cut-away portions substantially corre-- spend to the cutaway portions of the burnerplate 1l.

17 represents the cap or cover proper and is threaded, as shown at 18, to engage the correspondingly-threaded portions 19 of the member 13. This cap liis provided with an annular flange 20 above the threaded portion il, which ijirevents the cap being turned down into the member 13 more than a certain distance. The head of this cap is either squared or termed with sia sides for the application of a wrench, by which the cap may be screwed into place. '.lhe under surface of this cap is concave, shown at 21, so that when the cap 17 is in place over the steamway L1 an eXpansion-chamber is formed thereby. The use oi the spacer-plate 11 permits the cap 17 to be screwed down tight onto said spacer-plate and the cut-away portion of the spacer-plate insures the formation oi' the steam-discharge slot 22 of the requisite vertical width. It is Obvious, however, that if it is desired to increase the width or this steam-discharge slot the same may be readily accomplished by a partial turn oi the cap 17.

23 represents the partition in the center oi' the oil-discharge slot 10. This partition may be extended down into the oil way or chamber 3 or may be terminated slightly below the surface of the discharge-slot 10.

In Fig. et I have shown a slightly-modilied form of my invention. In this modiiication I have shown the cap 17 held in place on the top oit' the casing 2 by means independent of the cap. This means consists in providing a vcap-holding arm 23, provided at its forward end with a head 24, the under surface of which is adapted to rest on the top of the cap. This arm 23 is provided toward its rear end with side lugs 25, and the pipe 'is provided with lugs 26, which extend up above the arm 23 and are provided with undercut recesses 27, in which the lugs 25 are adapted to rest. The arm 23 is provided at its rear end with a threaded hole, and in this hole a bolt 28 is adapted to work. By adjusting thc bolt 28 the arm 23 may be caused to hold the cap 17 forcibly in place on top of the casing 2 or to release same, as may be required.

. The cap 17 of Figs. 4i. and 5 is substantially the union of the member 13 and the cap 17 and is provided with a lange 14, corresponding to flange 14C, and with a bead 16@ corresponding to the bead 16, and with a cutaway portion correspondingl to the cut-away portion of Figs. 2 and 3. In Fig. 5, however, I have shown the spacer-plate 11 as attached to the under side of the cap 17 and the center oil the under side of said cap concave at 21', so as to form an expansion-chamber for the steam. It will be noted, Figs. 3 and 5, that the bead 16 of the member 13 extends beyond the edges of the cut-away portion. By thus extending the ends of the seg'- mental ring the upward and outward iiow of oil through the oil duct or outlet 10 is so regulated that oil is only permitted to flow out from the oil-duct at a point away from the edges of the cut-away portion, and as the steam-discharge slot 22 is of the same width as the cut-away portion it is obvious that any possibility of the oil iiowing up over the edges of the cut-away portion is avoided and any possibility of carbonization on the cut-away is absolutely eliminated.

The operation of the burner is as follows: The pipe G is connected with a suitable steamsupply, and pipe 5 connected with a suitable 0il-supply,the oil being under slight pressure.

The steam passing through the steam-duct 4 and into the expansion-chamber formed above the opening 8 is evenly supplied to the steamoutlet 22 and lows over the face of the top plate and out over the oil-outlet 10 and draws the oil from the outlet 10 up into the steam, as the face of the iiange 12 is somewhatlower than the face of the top plate 7. rIhe Object of-tlie partition 23 is to prevent the oil all running to one side of the slot 10 when the burner is tipped from ahorizontal positionas, for instance, when a locomotive is roundingl a curve or when the burner is used on a ship and the ship is pitching with the sea.

Having now particularly described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, isw
