To all whom itmey concern.'

Be it known that JAMES Af. Wines, .lr.,.a citizen of the United Statesfresiding at Beaumont, in the county of Jefferson and StateA of Texashas invented certain new and useful Improvements in Injector-Burners;

and he does hereby declare the following to be a full,

vention; Fig. 2 represents a cross-section through the.

same on the line 2 2 of Fig. l; Fig. 3 represents a vdetail perspective view of the oil nozzle.

A designates the body of the burner having on opposite sides two inletopenings A A2, the walls oi. which i are screw-threaded for coupling them respectively to means for supplying oil and means for supplying steam. The oil flows normally from inlet A and a space a next to the saine, through a port 2 of an annular tapering valve-seat A3, integralvwith body A and centrally arv ranged with respect thereto, and a corresponding port l of a hollow valve B, into the interior ofthe latter, then down an oil discharge tube F which screws at the upper end into the center of the bottom oi the valve.

Thistube is concentric with the steam discharge tube G surrounding it, which is similarly screwed into the body B. 'The lower or outer end of said steam tube is tapered to iorm a nozzle G, at the mouth of which steam and oil are discharged together, mixing without injuriously obstructing eachother, the steam passing from space a next to steam inlet A? into the upper end of steam-tube G and down through., the space between ythe lat-ter and the oil-tube F, discharging at the nozzle G into the outer air. The oil tube/F is shorter than the steam tube GV and receives in its outer end telescopically the tubular stem h of an oil nozzle' H, having longitudinal, parallel, external ribs H and a taperingend h This end comes quite down to the end 'ofthe nozzle G, so that the oil and steam are discharged in the same transverse plane'simultaneously into the open airjtheoil in a central jet, the steam in a surrounding annular jet. Their close proximity and the force of the steam will completely vaporize the oil and mix the two vapors; but the steam has no access to the oil beqre the 'ly tr'jetsout andtherefore cannot obsttuctit. In noz- "zlesfmadewith the `lend of the` oil-nozzle or its equivalent arranged lto discharge leven slightlyr within the' nozzle Gf, the rush of the vsteam will often interrupt the ow of oil and driveit back, making the mixture very irregular and-uncertain and the injector burner incompletely operative.

The oil-nozzle H will sometimes be clogged by oil residuum,A To clean this away easily and instantly, Without displacing any part 0f the burner, I turn the valve B on its axis in either direction until .the port 2 of the valve seat is covered by the body oi said valve, and another port 4, in theopposite side of said valve-seat, communicates through one of two ports 3 and 5in said valvewith the interior of the latter. Steam then blows from inlet A through space a, port 4 and port 3 (or 5) l vand rushes down through the oil pipe and oil noazle,

quickly scouring the latter.

The oil ports 1 and 2 are very much wider than the steam ports 3, 4 and 5, to allow for the somewhat viscid character ofthe fluid passing through them. The ribs H ofthe oil nozzle hold it in proper position centrally within the discharge end of the main steam tube G and its terminal nozzleGf, leaving always an unchangeable fine annular space at the end ofthe latter forthe out- Y spouting of the steam.

Thevalve B is tumed,by means of an armor handle l on the outer end oi its stein B2, which passes up through a helical spring C bearing on said valve, a cap D screw-threaded into 'said body to hold said caplin place, a packing box d formed in the outer face of said cap, and a gland E screwed on and into said packing box. The said arm is detachably held in place vby a nutf screwed on the outer end of stem B. Theofce of said stem is to hold said valve snugly in its seat; but in practice it is found that the steam pressure on Ithe bottom of the valve, `which is exposed because the annular valve seat has no bottom, will sometimes overcome the spring and make the valve jumper rise in its seat; especially as such pressure is reinforced by the back steam pressure on the exterior of the tapering lower part of the oil-nozzle. To remedy this, I make a port 6 from the upper part of steam space a to the space C surrounding spring C, in order that .the steam may flow freely through the same and bear on the lbroader upper face of said valve,'counterbalancing the steam pressure on the underside above described and insuring the-suiiiciency of spring G and gravity to hold the valve in place.

Having thus describedsmy invention, what I claim as new and desire to secure by Letters Patent is:

1f In an injector burner, a three way valve, in combination-with a steam discharge tube, an oil discharge tube, separate inlets for said uids and s. spring bearing on said valve, the lutter being open on both sides-to the steam,

making s. balanced steam pressure and the said vulve being adapted to admit either ot said fluids at will to the oil vdischarge tubesubstantially as set forth.

2. In'an injector-burner for oli md steam, n. tma way vulve, n body having a seat for said valve, a spring holding said valve in its seat and an oil discharge tube and gleam discharge tube arranged cgncentrieal-ly, the smid -body having a port formed therein admitting steam from the steam inlet to the space about said spring fr balancing backward stem pressure and said seats'and vulve being provided witii ports for permitting at will the ow o oil or of stem through said oil tube, there. being alan s.,

f r eem pnalement pim 'e fer through mail] ste-1m inee substantially as sei forth.

v in teatimony whereof, 1f 'have signed my name to this speeiiicatien in the im;
