LIQUID-FUEL BURNER.

Application flied January 2,

To all whom it may concern Be it known that I, Gnonsr. EDMOND DEN- MAN, a citizen of the United States, and a resident of Fruitvale, in the county of Alameda and State of California, have invented a. new and Improved Liquid-Fuel Burner, of which the following is a full, clear, and exact description.

This invention relates to burners through which the liquid fuel is forced out into a fine, evenly subdivided spray, the particles fluid, by means of which the atomizing of the liquid fuel is obtained, and has reter ing an inner and an outer casing having independent inlets, one for fuel and the other for the compressed fluid, and a tip body secured to both of said casings and through which. the liquid fuel is forced by means of the compressed fluid.

The object of the invention is to provide an inexpensive, simple and eflicient burner which can be easily cleaned, repaired and its Wearing parts easily assembled.

' A further object of the invention is to )rovide a burner in which different tips can be used.

Reference is to be had to the accompanying drawings forming a partof this specifi cation in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal central section of an embodiment of my invention; Fig. 2 is a horizontal central section through the tip body; Fig. 3 is a modified form of the tip body; Fig. 1 is a perspective view of the cap; Fig. 5 is a perspective view of the distributing cup partly cut away to show the distributing orifices; Fig. 6 is a perspective view of the central dividing washer; and Fig. 7 is a perspective view ritlnuunpe a d lower spray-forming cut-away washers.

Referring to the drawings, 10 represents a compressed fluid inlet 12 leading to the through bore 11, and a liquid fuel inlet 13 lying opposite-the fluid inlet 12, both perpendicular'to the bore 11. The fuel inlet 13 leads to a central bore provided with a body portion 14 extending from the center of the cross member toward one end of'the same, and it is concentric with the bore 11. In the end of the bore 11 lying opposite the central body portion 14 is a threaded cap Specification of Letters Patent.

at the inner projecting end, provided with a valve head 18 normally forced against the adjacent end of the bore 15 by means of a coil spring 15) positioned on the plunger 17. By pulling on the exteriorly projecting end of the plunger 17 the I spring 19 is compressed and the valve head 18 of the plunger 17 is drawn away from the through bore 15 thereby establishing communication between the bore 1.1 and the bore 15.

Connected exteriorly to the cross member 10 by means of a union 20 is a nipple 21 axial with the bore 11 and at the end to ward which the central body portion 14 extends. A tubular member 22 13 secured centrally to the body portion 14 axially with thebore 15, and the said tubular member 22 projects out at the opposite end of the nipple 21. Secured directly to the tubular portion 22 and to the nipple 21 by means of a union 23 a plug having a central bore 24 and a plurality ofpassages 26. A cap 27 is screwed to the other end of the plug 25 and it has a. through bore substantially equal to the end bore of the plug 25. 'llhreaded into the central bore 24 of the plug 25 is a tip body 28, having a shoulder 29 abutting snugly 'against the free nonthreaded end of the cap 27. By screwing off the cap 27 from the plug 25, the abutting joint between the tip body and the cap is made tight. The tip body 28 has a semispherical end portion provided with a slit 30 connected to the central passage 31 of the tip by means of a flattened passageway 32 converging from the slit toward the bore. The'portion of the tip lying in rear of the shoulder 29 is conical, and its slope is parallel with the slope of the passage 32 A pair of apertures 33 is provided in the coneshaped portion of the tip opposite each other and converging toward the end of the passage 32 and terminating in the flattened Another pair of passages 34 is provided in said cone-shaped portion opposite each other and at right angles to the passages 33 in the beveled sides-of the passage 32. As the

passages

33 and 34 lie exteriorly on the same circle on the cone-shaped portion of the tip they terminate inwardly at difierent distances from the end of the tip due to the fact that one pair enters the flattened 'portion of the passage 32 and terminating while ithe other pair said shank communicating With said outlet passage on the shank and having distributing apertures'in the'bottom thereof, a plu-' rality ofWashers between said oupand said central eXtensiph, and a threaded cap on said shank closing said cup and maintaining same on said Washers in a predetermined position, certain of said Washers below said cup and above said central extension having.

cut-away portions in alinement with each other and under said distributing apertures of said cup.

3; A device "of the class described com: prising, an exterior tubular member and an interior tubular member; a plug at one end secured to said exterior and said interior tubular members, said plug having'a central passage communicating with said inner tubular member and a plurality of passages surrounding said central passage communicating with said exterior tubular member; a

tip body secured to said plug and having a 'central passage communicating With said sage communicating-With said surrounding passages in said plug, said passages in said tip body having, acommon outlet at the tip end, said .central passage of said tip having an outlet above said common outlet; and a' cross member secured to said exterior and interior members at the end opposite said plug and having independent inlets to said exterior and interior tubular members.

In testimony whereof-I have'signed my name to this specification'i'n the presence of two subscribing Witnesses.
