Specification of Letters Patent. Application filed July 18,

Patented April 7, 1908. 1907. Serial No. 384,353. 7

To all whom it may concern:

Be it known that I, JACOB OSBORNE MOR- GAN, a citizen of the United States, and a resif dent of Oakland, in the county of Alameda and State of California, have invented a new and Improved Burner, of which the following is a full, clear, and exact description.

The invention relates to hydrocarbon burners, and its object is to provide a new and improved burner for burnin fuel oil, and especially designed for use in Boiler furnaces and other places, and arran ed to insure complete combustion of the fuel without forming undesirable residue, and to permit using a low grade oil.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention 1s represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the improvement as arranged for use in boiler furnaces Fig. 2 is an enlarged sectional side elevation of the improvement on the lines 22 of Figs. 1

3; Fig. 3 is a sectional plan view of the same on the line 33 of Fig. 2; Fig. 4 is a sectional side elevation of a modified form of the improvement, the section being on the line 44 of Fig. 5, and Fig. 5 is a sectional plan view of the same on the line 5-5 of The atomizing chamber A of the burner is preferably made cylindrical in form and provided in its peripheral face with an exit slot B through which passes the combustible mixture to be burned, as indicated in Fig. 1. Into the atomizing chamber A opens a nozzle O directly opposite the slot B, and the said nozzle O forms part of a steam chamber O connected with one end of a steam pipe D bent to pass around the atomizing chamber A in alinement with the slot B, so that the burning mixture strikes the steam pipe D and su er-heats the steam passing through the sai ipe D previous to the steam entering the c amber C and the atomizing chamber A. The steam pipe D is connected with a boiler or other suitable source of steam su ply.

n the atomizing chamber A extend a plurality of spaced pins E having flattened portions E facing the nozzle O and also facing I the perforations in perforated pipes F, connected with the interior of an oil supply chamber G connected by a pipe H with an oil su ply. As illustrated in the drawings the o' chamber G is provided with a threaded offset G which screws into the bottom of the atomiz g chamber A, and the pins E as well as the ipes F are preferably attached to the oil chamber G at the said threaded offset G. Thus by unscrewing the oil chamber G from the atomizing chamber A, convenient access is had to the several parts of the burner for cleaning, re airing or other purposes. Now when the urner is in use, the super-heated steam passes from the steam pipe D into the chamber C, and from the latter by way of the nozzle O into the atomizing chamber A, and the oil passes from the oil chamber G either by pressure or gravity feed through the pipes F and the perforations thereof into the atomizing chamber A, to be taken up by the steam and forced by the latter against the flattened portions E of the pins E, to thoroughly atomize the oil, and to insure a perfect commingling of the atomized oil andthe steam. The resultant combustible mixture passes through the slot B to be then burned in the furnace or other device on which the burner is used.

As illustrated in Figs. 4 and 5, the oil cham ber G is dispensed with and the atomizing chamber A is provided with a slot B, and is closed at the bottom by a cap I held in place on the atomizing chamber by bolts J extending through the said chamber. The ca I carries the atomizing pins E having fl attened ortions E facing the entrance O located irectly opposite the slot B. Into the entrance O extends the nozzle K of a steam pipe K, and into the said entrance C also opens the oil supply ipe L connected with a suitable sourceof 0 supply. Now by the arrangement described the steam passin through the nozzle K draws oil through the pipe L into the entrance O to be mixed with steam and forced by the latter against the flattened surfaces E of the pins E to insure a complete atomizing of the oil and commingling of the oil and the steam. The resultant combustible mixture then passes from the atomizing chamber A by way of the slot B into the fire box of the furnace, to be burned therein.

The burner shown and described is very 7 against the flattened sides simple and durable in construction and composed of comparatively few parts, not liable easily to get out of order.

As the oil is divided in passing through the perforations of the pipes and is then forced by the steam against the flattened portions E .of the pins E, it is evident that the oil is thoroughly atomized and burns in the fire box with a pure white flame, thus insuringcomplete combustion of the fuel.

By the arrangement illustrated in Figs. 4 and 5, the oil can be drawn by the action of the steam passing through the nozzle K from a suitable reservoir without requiring pressure on the oil.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent:

1. A burner comprising an atomizing chamber having a removable bottom, spaced pins carried by said bottom and extending vertically in the said atomizing chamber when the bottom is in position, and means for forcing oil and steam into the said chamber against the said pins, to s ray the oil and cause an intimate comming ing of the oil and steam.

2. A burner comprising an atomizing chamber, a removable closure for said chamber, a series of spaced pins carried by said closureand extending across the said atomizing chamber when the closure is in position, the said :pi-ns having flattened portions facing the entrance of the said atomizing chamber, and means for passing oil and steam separately into the said atomizing chamber and directing thesame against the flattened sides of the pins.

3.. A burner comprising an atomizing chamber, an exit slot opposite the entrance of the atomizing chamber, a removable closure for the atomizing chamber, the closure being provided with spaced pins projecting from its inner face and extending across the atomizingichamber when the closure is in position, the said pins having flattened portions facing the entrance of the said atomizing chamber, the said pins having a staggered arrangement relative to the entrance and the exit slot of said chamber, :and means for passing oil and steam separately into the said atomizing chamber and directing the same of the pins.
