OIL-BURNER.

Specification of Letters Patent.

PatentedFeb. 1, 1921.

Application filed October 30. 1913. Serial No. 334,379.

2'0 all whom it may concern;

Be it known that 1, JOHN UHAnLnsED- MUND, a citizen of the 'United States, and a resident of Shanghai, China, have invented a new and Improved Oil-Burner, of which the following is a full, clear, and exact description.

This invention relates to an improvement in oil burners, an object of the invention being to provide means for vaporizing the oil, and an improved burner lip or tip which permits a free commingling of the vapor and steam to insure a proper burning action.

A further object is to provide a burner of the character stated, andwhich is capable of receiving burner tips having different arrangements of grooves and recesses so asto permit of an adjustment in accordance w th the fuel oil and steam employed.

With this and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

in the accompanying drawings- Figure 1 is a plan View, partly broken away;

Fig. 2 is a view in longitudinal vertical section;

Fig. 3 is a view in transverse section on the staggered line 3-3 of Fig. 2; and

Fig. 4 is a view in section on the line 4-4 of Fig. 2.

1 represents a metal casing which comprises two castings 2 and 3, having flanges 4 at their longitudinal edges, secured together by bolts 5 and nuts 6. These castings 2 and 3 provide in the upper portion of the casing a relatively long vaporizing chamber 7 and below the same a steam chamber 8. An oil supply pipe 9 communicates with one end of chamber 7 and is connected to the casting by any approved coupling 10, a strainer 11 being secured between the pipe 9 and the end of the casing 1 and projecting into the vaporizing chamber 7 An integral internally screw-threaded nipple 12 is provided on top of the casting 2 adj acent its inlet end, and receives the by-pass pipe 13 which may supply the air to the vaporizing chamber. '1 he top of the casting 3 constitutes the bottom of the vaporizing chamber 7 and is made with a plurality of projections 15, preferably having a staggered arrangement as shown clearly in Figs.

1 and 3, and these projections are heated to a high degreeand cause a thorough vaporizat lon of the oil. The lower casting 3 is made with an internally screw-threaded nipple 16, rece1v1ng a steam pipe 17 for supplying the necessary steam to chamber 8. i

"'At the outlet end of the burner a burner t p 18 is located. This tip 18 is located inslde of the casing and positioned in the castlng 3, suitably recessed to receive the same and secured by means of screws 19 so that the tip can be removed and replaced by another having a different formation of recesses for the passage of vapor and steam to give the desired results for the burner. The tip 18 is made in its lower portion with a recess 25.- for the passage of the steam, and in its fron face with a recess 21 for the passage of the vapor to commingle with the steam at the lower portion of the tip. The end wall of the casing adjacent the tip 18 is inclined, as

tion of the tip but provides a burner orifice 23 at its lower end which terminates short of the bottom of the casing. The casting 3 below the tip 18 is made with a longitudinal recess 24 which cooperates with the recess 20 to provide a steam passage under the tip.

The operation is as follows:

The oil entering through the pipe 9 and strainer 11 is vaporized by reason of the hot metal surface in vaporizing chamber 7 and commingles with the air and is discharged in the form of vapor over the tip 18, commingling with the steam from chamber 8 which passes under the tip 18, and the mixture is burned at the orifice 23.

Various slight changes may be'made in the general form and arrangement of the parts described without departing from my invention, and hence I would have it understood that I do not limit myself to the recise details set forth and consider mysel at liberty to make such changes and alterations as fairly fallwithin the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secureby Letters Patent is:

1. An oil burner comprising a casing having an upper vaporizing chamber and a lower steam chamber, an inclined tip secured in the outer endof the casing and providing an outlet from both he vaporizer and the steam chambers, and integral conical proj ections having staggered arrangement in the shown at 22, so that it covers the upper porbase Wall of the vaporizing chamber, said inclined tip extending across the outlet end projections adapted to be maintained at a of the steam chamber having a recess in its 10 uniform heat. .lovver edge for the passage of steam and a .2. An oil burner, comprising a casing havrecess in its outer face for the passage of 5 ing an upper vaporizing chamber and a vapor, and said casing at its outer end havlovver steam chamber, projections on the ing an inclined Wall located against the uplower Wall of the vaporizing chamber having per portion of the tip. staggered arrangement with each other, an JOHN CHARLES EDMUND.
