Application filed August 25, 1908. Serial No. 450,210.

a citizen of the United States, residing in Los Angeles, county of Los Angeles, and

Y State oi California, have invented new and usefull improvements in Hydrocarbon-Burners, of which the following is a specification.

My invention Vrelates to the class of hydrocarbon burners in which crude oil, or other liquid-fuel is burned by the aid ofV some` eXpansible-iiuid, such as steam, or compressed air, and the object thereof is to produce a burner in which the expansible-iluid can be delivered into the combustion chamber below the liquid-luel in a broad thin stream which can be readily regulated as to the thickness of the stream by the operator? l accomplish this object bythe burner described herein and illustrated in the accompanying drawing, in which,

Figure 1 is a central longitudinal section of the burner tip and showing the iront wall of the combustion chamber and a ortion oi the supply pipes. parts shown in Fig. 1, a portion of the burner tip being in section. Fig. 3 is a front elevation of the burner tip. Fig. lis a rear elevation oi the burner tip. Y

` In the drawings 5 is the iront wall of the combustion chamber andis provided with an opening 6 therethrough which is covered by a cap plate 7 ii' desired, said cap plate having holes through which the projecting exterior part of the burner and the supply pipes extend. The burner tip is composed of a body piece 8 which is preferably cylindrical in shape with the lower portion thereof of less diameter than the upper portion. In the up er portion is a transverse liquid-fuel channe 9 which` extends through the head. The rear end of this channel is enlarged and interiorly threaded `for the reception of the fuel supply pipe 10 which screws into the head. This supply pipe is rovided with a cock 11 to regulate the supp y ofiuel to the burner, and runs to a supply of liquid not shown. Extending longitudinally and cen-V trally and then transversely in the lower portion ofthe-body piece is the eXpansiblefluid channel12 best shown in Fig. 1. This channel opens in a port atV the front of the burner just below the liquid-fuel channel port and a little back of the same. Around the outlet, the body piece is cut away to form a recess 13 best shown in Fig. 3. On the lower reduced portion ofthe body piece is a sleeve Fig.. 2 is a p an ofthe 14 whichis provided with an upwardly proj ecting lip 15, which lip is adapted to lit into the recess 13 to close the same when the upper portion' of the sleeve is in contact with the enlarged portion of the body. The outlet of channel 12 is square and preferably of the same width as lip 15 so that the expansiblefluidV will issue from said channel 1n a thin broad stream when the sleeve is moved downwardly on the body.

yln the back portion of the sleeve is an elongated opening 16 in which is received a cam 17 which is mounted eccentrically on rod 18 to which it is rigidly secured by a pin 19 which passes through the cam and rod to secure the parts together. The inner end of rod 18 passes into a recess 20 in the body piece andis revoluble therein, so that as rod 18 is'rotated the sleeve is moved up or down on the body to open or close port 21 which is formed between lip 15 and the upper part of the body piece. its parts secured together by screws 23 and having an opening 24 through which stem 18 passes, holds the cam from separating from the sleeve. A plate could be fastened to the sleeve to hold the cam in place. A supply pipe 25 provided with a regulating cock 26 passes through the furnace wall and projects in front of the burner tip and then rearwardly and connects to channel 12 in the burner tip to supply eXpansible-iiuid from a source of supply not shown. If desired the body piece of the top could be of uniform diameter and the eXpansible iiuid channel open at the surface thereof and the sleeve could be placed on the outside of the lower A two part strap 22 having portion 'of the body piece and be operated by the cam to open and close the port of channel 12. That portion of the eXpansble-iiuid pipe which projects in front of the burner tip may be termed a superheater and if desired the same could be omitted, but I prefer its use because it better prepares the expansiblefluid for combustion.

`larged upper portion of the body piece and having an eXpansible-luid channel terminating in a square port in said recess and a liquid-fuel channel terminating in a port Yio above said recess; a sleeve slidably Inounted upon the lower portion of said body piece, said sleeve having` a lip projecting upwardly and adapted to nt into the recess of the 'upper portion of the body piece and lmeans to move said sleeve longitudinally upon said body piece.

2. A hydro-carbon burner comprising' a cylindrical body piece and having the lower portion of less diameter than the upper portion and provided with a liquid-fuel channel and an eXpansible-iiuel channel and a recess in the top portion, said expansible- Huid channel terminating in a square port in said recess; a sleeve provided with a lip and slidably mounted on the lower portion of said l body piece, said sleeve having an elongated openlng in the back portion thereof; a rod revolubly mounted in the lower parts ol said body piece; a cani. eccentrically mounted on said rod, said cani beingr adapted to work in the opening' in said sleeve; and means to prevent said cain from accidentally separatiner from said. sleeve.

In witness that I claini the foregoing l 12T have hereunto subsorihed in v naine this 10th day of August7 1908.
