UNITED STATES JOHN H. REEVE, OF PORTLAND, OREGON.

LIQUID-FUEL BURNER.

Application filed January 4, 1928.

My invention relates to liquid fuel burners and its principal object is to provide a'burner of this type wherein a maximum supply of air is had and the consequent reduction of liquid inafter specifically referred to, claimed and illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of liquid fuel burner constructed in accordance with my invention;

Figure 2 is an enlarged longitudinal sectional View of the same; and

Figure 3 is a vertical section taken on line 83 of Figure 2.

Referring to the invention in detaila cylinder or shell 5, divided intermediate its ends by a transverse partition 10 to afford chambers 11 and 12, is provided. The chamber 11 constitutes a steam and oil mixingchamber,'while the walls of the chamber 12 are provided with air inlet openings 13 to supply oxygen to this latter chamber.

Caps 14 and 15 are threaded upon the opposite ends of the cylinder or shell having central threaded openings 1 and 2, the former threadedly receiving an oil supply pipe 16 which passes intothe chamber 11, and the latter receiving an outlet pipe 17 having one end disposed within the chamber 12 and flared as at 18.

The pipes 16 and 17 are disposed in longitudinal alinement, and arranged within the cylinder or shell in longitudinal alinement with these pipes is a mixing tube 19, the latter passing through the wall 10 in threaded engagement therewith, as at 19. As illustrated in Figure 2, the forward end of the mixing tube is flared as at 20 and disposed in close proximity to the inner end of the pipe 16 to receive oil discharged therefrom, while the opposite end of this tube is disposed'in close proximity to the flared end 18 ofthe tube 17 to discharge the combustible mixture therein. A hollow boss 23 formed on the cylinder or Serial No. 244,450.

shell 5 communicates with the chamber 11 and receives the threaded end 24 of a steam supply pipe 25.

Projecting forwardly from the cap 15 and receiving the outlet tube 17 is a cylindrical burner tube 26 formed with a frusto-conical burner or head 27. To secure this burner tube in place, a bushing 28 having threaded engagement with the tube 17 is engaged with thfi interiorly threaded inner end 29 of the tu e.

It will be observed that the steam and oil or other liquid fuel will mix as it passes through the mixing tube and thence discharge into the outer tube 17. As the mixture passes from the .mixing. tube and into the outlet tube a vacuum is produced within the latter, drawing air through the openings 13 to supply the necessary oxygen to the mixture be fore it passes to the burner 27.

What is claimed is:

1. In combination a shell perforated for I part of its length, a. partition extending transversely within the shell and disposed to one side of the perforations and having a. central opening, a. tube passing through the opening and having one end flared, a liquid fuel supply pipe passing through oneend of the shell and having its inner end disposed in close proximity to the flared end of the tube, an outlet pipe passing through the opposite end of the shell and having its inner end flared and disposed in close proximity to the adjacent end of the tube, and means for discharging steam in the shell in the vicinity of the liquid fuel supply pipe.

2. In combination a shell having perforations therein for part of its length, a partition extending transversely within the shell and disposed to one side of the perforations and having a central opening, a tube passing through the opening, a liquid fuel supply pipe passing through one end of the shell and having its inner end disposed in close proximity to one end of the tube, and an outlet pipe passing through the opposite end of the shell and having its inner end disposed in clqjse proximity to the opposite end of the tu e.

Signed at Portland, in the county of Multnomah and State of Oregon, this 19 day of November A. D. 1927.
