JOHN FRED DEE AND JOHN '1". WHITLOCK, OF CHICAGO, ILLINOIS.

CRUDE-0H4 BURNER.

Application flied March 17, 1923. Serial fie. 625,712.

To all whom it may concern:

Be it known that we, JOHN FRED .DEE and JOHN T. WHrrLooK, both citizens of the United States, and residents of the city of Chicago, in the county .of Cook and State of Illinois, have invented certain new and useful Improvements in a Crude Oil Burner; and we do hereby declare that the following is. a full, clear, and exact de scription of the same, reference being had to the accompanying drawings and to the numerals of reference marked thereon, which form a part of this specification.

This invention relates more particularly to an improved crude oil burner adaptable for external use in connection with no-coal furnaces and the like and provided with means so constructed that oil entering spiral grooves in a nozzle plug member is thoroughly broken up by air jets entering the spiral grooves so that the air is carbureted with the oil to form a fuel which is discharged through an adjustable restricted nozzle. and lighted to direct flames into the furnace or other device to heat the same.

It is an object of this invention to provide an improved simplified crude oil burner adapted to be mounted on the exterior of furnace wall having an opening 2 therein a furnace to direct oil flames into the firebox of the furnace.

It is also an object of the invention 'to provide a crude oil burner wherein a spirally grooved passaged plug is mounted in the nozzle of the device to cause air passing through the plug to be thoroughly carbureted with crude oil passing through the spiral grooves of theplug. 7

It is a further object of the invention to provide a crude oil 'burner wherein a nozzle plug is provided having spiral oil grooves having air passages communicating therewith to facilitate thorough mixing of the oil and air passing through the nozzle of the burner.

It is furthermore an object of this invention to provide a crude oil burner wherein the nozzle is provided with an adjustable tip.

It is an important object of the invention to provide a crude oil burner of simple and effective construction wherein crude oil passing through the burner is conducted through spiral grooves of a nozzle plug member and is thoroughl disintegrated by means of currents 0 comthe :inner end of the pressed air which are directed into said spiral grooves to mix with the oil and provide a properly carburetedfuel which when burning will not act to corrode the burner parts.

Other and further important objects of this invention will be apparent from the disclosures in the specification and the accompanying drawings.

The invention (in a preferred form) is illustrated in the drawings and heroin- Figure 2 is an enlarged longitudinal sec tion of the burner with parts in elevation.

Figure 3 is an enlarged transverse sec tion taken on line 3--3 of Figure 2..

Figure 4 is an enlarged longitudinal sec tional view of the burner nozzle plug, tak en on a line centrally through the spiral grooves therein. 7

As shown on the drawings: The reference numeral 1 indicates a closed by a centrally apertured closure plate 3. I

The crude oil burner comprises ametal cylindrical housing 4 having an enlarged head 5 integrally formed ,on one end thereof. Integrally formed on the end of the head-5 is an externally threaded ring h flange 6 spaced between the inner and outer peripheries of said head. An apertured disk 7 is seated within the head flange 6 and has threaded therein one end of :2. pi e or tube 8 which projects longitudina y through the head 5 and housing 4. The other end of the tube 8 has threaded thereon a spider or plu 9 which fits in the end of a housing 4. e plug 9 is provided with; a conical valve seat 10 and has a plurality of lugs 11 integrally formed on the end thereof and flush with the end of the housing.- The plug 9 is provided with a longitudinal air passage 12 connecting the interior of the housing 4 with the space between the outer end of the plug 9 and plug 30. An air intake opening is provi ed in the bottom of the head 5 and has threaded therein one end of an air supply pipe 13, the other end of which is connected with any suitable source of compressed air.

Engaged against the end of the head flange G and against the disk 7 and tube 8' is a packing disk 14 held in place by means of a closure cap or head 15, one end of which is recessed and internally threaded to permit the cap 15 to be threaded onto the flange 6 and against the packing disk 14. The cap 15 is provided with an L-shaped oil intake passage 16, the inner arm of which communicates with the oil tube 8. The other arm of the oil intake passage 16 opens through the bottom of the cap 15 and is internally threaded to receive the threaded end of a crude oil supply or feed pipe 17. The oil supply pipe 17 is connected with an oil supply tank (not shown).

A recessed nipple or boss 18 is formed on the cap 15 and is externally threaded to receive a stufling box or nut cap 19 which holds a packing 20 within said nip le around a valve stem or rod 21. The valve stem 21 projects through the cap 15 and through the tube 8. A threaded portion 22 of the valve stem 21 has threaded engagement with the cap 15 and permits the valve stem to be adjusted by means of a knurled handle or knob 23 fixed on the outer end of the valve stem. Rotatably engaged on the inner end of the valve stem 21 is a frustumshaped valve 24 adapted to coact with the valve seat 10, to control the flow of crude oil from the tube 8. Attention is called to the fact that the end of the valve 24 ends short of the valve seat 10 leaving a small space at the outer end of said valve seat to permit a pocket of oil to accumulate there to form an oil seal which prevents back firing into the oil tube 8.

Threaded onto the end of the housing 4 is a collar 25 of a tapered or conical nozzle 26 having a restricted discharge passage 27. The end of the nozzle 26 is externally threaded and has adjustably engaged thereon a flaring discharge tip or mouth piece 28 having a flaring opening. 29 therein which regis ers with the restricted passage 27.

Placed within the nozzle 26 is a carbureter plug 30 of conical shape and having two oppositely positioned spiral, grooves 31 extending the length of said plug. The enlarged end of the plug 30 is provided with a curved or concave recess 32. The spiral grooves 31 divide the plug into two sections. Each half or section of the plug is provided with a plurality of air passages 33 which open into the recess 32 and also communicate through one wall of one of the grooves 31 as illustrated in Figure 4.

The operation is as follows:

The crude oil burner is mounted on the exterior of the furnace 1 with the nozzle only projecting through the opening in the furnace closure plate 3, as illustrated in Figure 1. The pipe 13 is connected with a source of compressed air, while the pipe 17 is connected with a crude oil supply tank or pump.

\Vhen the burner is assembled the plug 9 is set so that the lugs 11 rest against the enlarged end of the carbureter plug 30 in the position illustrated in Figure 3.

The valve 24 is rotatably mounted on the valve stem to permit the valve to seat properly in the valve seat. The valve is opened by turning the handle 23, thereby permitting crude oil to be pumped through the pipe 17 and the passage 16 through the tube 8 and the valve seat opening in the p ug 9. The crude oil is thus forced against the enlarged end of the plug 30 and into the spiral oil grooves 31. As the oil is directed into the spiral grooves 31 it is directed against the convex walls thereof.

The compressed air from the pipe 13 enters the housing 4 and flows through the plug passage 12 into the plug recess 32 and through the air passages 33, thereby directing the flow of air into the grooves 31 and against the convex walls of said grooves.

The air thus acts on the oil tending to disintegrate the same so that the air will become thoroughly carbureted with the oil to produce a fuel which will flow from the ends of the spiral grooves 31 into and through the restricted nozzle outlet passage 27 to be discharged through the burner tip 28 into the furnace. The projected fuel is of course lighted to provide the flames which act to heat the furnace. The tip 28 may be adjusted on the nozzle to regulate the size and form of the flames directed into the furnace. The valve seat 10 in the plug 9 is longer than the valve 24 and affords a pocket to the outside of the end of the valve. Oil from the tube 8 passing around the valve fills the pocket and-acts to eliminate all possibility of back fire which is one of'the main objections to other types of crude oil burners.

We are aware that numerous details of construction may be varied through a wide range without departing from the principles of this invention, and we therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.
