' AND CHARLES I. SEABUBY & CO.,CONSOLIDATED, OF NEW YORK, N. Y., A COR- PORATIOIQ' 01" NEW YORK.

To'all whom it may concern:

Be itknown that 1, JAMES Minnoum a citizen of the United States, and a resident of the city of New York, borough of Bronx, in the county of Bronx and State of New York, have invented a new and Improved Hydrocai'bowBui'ner, of which the following is a full, clear, and exact de- .of reference indicate corresponding parts in all the views, and Figure 1' is a side elevation of an embodiment of my invention; Fig. 2 is a cross section thereof on line 2-2, Fig. 1; Fig. 3 is a horizontal section on line 3-3, Fig. 2-; Fig. 4 is a cross section on line 44, Fig. 1;. Fig. 5 is a longitudinal section through the needle valve controlling the feed of the fuel to the mixing chamber; Fig. 6 is a cross section through the wick; Rig. 7 is a cross section through a modified structure of the wick; and Fig. 8 is an elevation thereof.

Referring to the drawings, A is a retort wick formed of a metallic gauze fabric 9 of very thin mesh wound on a central rod 10. The rod 10 projects at both ends of the said roll of gauze. wound about it; and at one end the roll is clamped by the end of the rod to the rod. The gauze roll can be secured to the other end of the rod in any suitable way; as shown, it is tied to the rod 10 by a wire 11. The end of the rod adjacent the wire 11 is in the shape of a hook, so that the same can be easily engaged for manipulation. The diameter of the roll of gauze 9 is substantially equal to the diameter of the vaporizing chamber 12, the rear end of which is connected to the alcohol-supply pipe 13. At the front end the vaporizmg chamber is provided with a plug 14 which Specification of Letters Patent.

valve .16 which controls the outlet of the gasified fuel coming from the vaporizing chamber to the tubular portion 15. The gaseous fuel is directed by the needle valve 16 into a mixing conduit 17 spaced from the conduit 15 by an air gap. The said mixing conduit 17. leads to a mixing chamber 18,

preferably of cylindrical form and connected to the vaporizing chamber by suitable brackets 19. The said mixing chamber 18 is apertured, as best seen in Fig. 3, and forms the burner proper. It will be noted that the wick A extends substantially through .the entire length of the vaporizing chamber and over the passage leading to the tubular portion 15. The chamber 18 has additional perforations 21 on the side thereof below the vaporizing chamber, whereby heat is positively supplied to the vaporizing chamber. The heat of the fuel burning at the perforations of the mixing chamber will easily gasify the fuel sub-divided into minute particles by the gauze forming the wick. It is self-evident that by forming the wick from gauze the. fuel is split up into mi- .nute particles exposed on an exceedingly large surface; and under the action of heat the same will readily gasify and thus a uniform feed of gaseous fuel will flow through the outlet in the tubular portion 15 controlled by the needle valve 16. Thus, a greater economy of fuel is obtained and a more efficient burner results.

Secured to the mixing chamber and positioned below the same is a heating pan 21 which extends with one end thereof beyond the gap between the tubular portion 15 and the mixing conduit 17. The heating pan has an overflow 22 directed to a closed receptacle and normally preventing the alcohol from flowing over the edges of the pan around the burner and causing fire, due to the inattention of the operator. The alco- Patented Nov. 7, 19156. Application filed December 31, 1914. Serial No. 879,809.

hol is normally supplied to the pan by the needle valve, as before the vaporizing chemher is heated the alcohol flows through the needle valve in liquid form and not in the form of gas.

In burners of large diameters, in lieu of using a roll of gauze wound on a rod, as shown in Fig. 6, a gauze container 20 may be formed supported by a rod 10, and which container may be filled with mineral Wool, or other similar substance. to cause the fuel passing therethrough to be sub-divided into minute particles disposed on a large area.

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

In a hydrocarbon burner, a tubular vaporizing chamber, a branched-out conduit from said vaporizing chamber, a needle valve controlling the outlet from said conduit, a mixing conduit adapted to receive the fuel controlled by the needle valve and separated from said branching out conduit by an air gap, a tubular mixing chamber associated with the mixing conduit, said mixing chamber having perforations on the lateral surface thereof, means connecting said vaporizing chamber to said mixing chamber adjacent the perforations, a metallic gauze fabric roll in said vaporizing chamber between the fuel supply and the branching-out conduit, and a heating pan below the chamber and extending beyond the air gap to receive fuel from the branching-out conduit, said pan having an overflow leading to a closed receptacle substantially. as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
