OIL-BURNER.

To all whom itpmcy concern Be it known that I, EDWARD A. Hnnmno TON, a citizen of the United States, residing Another aim of the invention is to pro-- vide in a device of this class a novel form of burner head or nozzle which may be readily cleaned in the event that the same becomes clogged. i

Another aim of the invention is to provide a novel arrangement of the steam and liquid fuel. supply pipes which will permit of the fuel supply pipe being cleaned whenever desired without the necessity of separating the several parts of the structure.

In the accompanying drawings:

Figure 1 is a side elevation of the burner embodying the present invention;

Fig. 2 is a vertical sectional view therethrough.

Fig. 3 is a perspective view of the discharge end of the fuel tube of the burner nozzle.

Corresponding and like parts are referred to in the following description and indicated in all the views of the accompanying drawings by the same reference characters.

In the drawings the numeral 1 indicates a liquid fuel supply pipe which leads from any suitable source of supply and which is provided with a branch 2 provided at its end with a T indicated by the numeral 3 the said branch entering one end of the T and the T being provided at its other end with a plug closure 4- which may be removed if it is desired to clean the branch other than in a manner to be presently described. The numeral 5 indicates a steam supply pipe which is connected by a T 6 with branches 7 and 8. The branch 7 opens into the casing 9 of a cut-off valve of the ordinary type, this valve being provided with the usual 1 handle 10 permitting of its ready manual opening and closing. The pipe 1 is provided with a short branch 11 which also communicates with the valve casing 9 and Specification of Letters Patent.

Application filed August 2, 1916 Patented Aug. 21, 1917.

Serial No. 112,770.

by reference to Fig. 2 of the drawings it will be understood that when the valve proper, which is indicated by the numeral 12 is closed no steam can enter the branch 2 of the pipe 1 by way of the valve casing. However, under conditions to be presently explained the valve 12 is to be opened for the purpose of admitting steam to the said branch 2 of the pipe 1.

The burner proper includes a connection 13 into which is fitted the end of the branch 8 which leads from the supply pipe 5 and threaded through the lower end of the said connection 13 is the lower end of the fuel tube of the said burner this tube being indicated by the numeral 14:. The lower end of the said tube lt extends below the lower end of the connection 13 and is threaded into the branch of the T 3. Threaded into the upper end of the connection 13 is the lower end of the steam tube of the burner indicated by the numeral 15 and connected to this tube at the upper end thereof by a mechanical expedient, the head may be considered integral throughout for convenience in describing the same. The head is indicated in general by the numeral and the lower portion thereof is provided with a neck 21 which is exterior-1y threaded as at 22 and fitted to the said neck is a collar 23 having an inwardly projecting flange 24 which engages beneath the enlargement 18 of the member 17 the neck 21 of the burner head at its lower end being interiorly circumferentially beveled as at 25 and the said bevel seating against the convex surface 19 of the enlargement 18 thereby forming, when the collar 23 is tightened, a steam-tight fit between these parts.

By reference to Fig. 2 it will be observed that the fuel tube 14 extends upwardly through the tube 15 and at its upper end eX- tends into the neck of the burner head 20, the tube 15 being internally of a greater diameter than the exterior diameter of the tube 14 so as to permit of the flow of steamtherethrough to the burner head,

I Fitted to the upper end of the fuel tube 1 1 is a discharge tip 26 the tip being preferably removably threaded onto the said end of the tube and being provided with a closed top 27 and in its opposite sides witlrdischarge orifices 28 preferably in the nature of narrow slots. Theburner head 20 is substantially dome-shaped its larger end being of course its upper end and consequently as steam passes up through the tube 15 and past the tip 26 it is permitted to expand within the'said burner head. The flow of steam past the said tip will of course induce flow of liquid fuel through the orifices 28 of the said tip into the head and the steam will of course vaporize the fuel before it issues from the head. In the present instance the vaporized fuel is discharged from the burner head in a sheet or film and in order that this maybe accomplished the head is provided in one side with a discharge ,orifice 29 which extends a greater ,or less'distance around the said head and which,like the orifices 28 ispreferably in the nature of a relatively narrow slot, It will be apparent that prior to discharge of the fuel through the orifices 28, the fuel as it passes upwardly through the tube 14 is subjected to the heating action of the steam Within the tube 15 and therefore it is more readily. vaporized,

Ccpies pf this patent may be obtained for .out through the tip 26 any accumulations within the said branch 2 and the fuel tube.

Having thus described the invention, what isclaimed as new is:

In a liquid fuel burner, a steam tube, a

union having an upstanding branch, a lat eral branch, and a downwardly extending branch, the steam tube being fitted at its lower end into the first-mentioned branch of the union, a steamsupply pipe fitted into the lateral branch of the union, a hollow mixing head fitted to and in communication with.

the steam tube at the upper end thereof and having a{ discharge orifice, a fuel supply pipe fitted at its lower end in the downwardly extending branch of the union and extending upwardly within the union and within the steam tube and spaced from the walls of the steam tube, the upper end of the fuel tube extending within the mixing head and providedwith'a discharge orifice, and a fuel supply pipe communicating with the lower end of the's'aid fuel tube.

In testimony whereof I affix mysignature.
