To a/ZZ whom, it may con/cern,.-

Be it known that 1, HERMANN MERKEL, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented a new and useful Improvement in Hydrocarbon-Burners, of which the following is a specification.

Figure I is a side elevation of a hydrocar-v Referring to the drawings in detail, the

cylinder 1 constitutes the principal feature of my invention, and in form it remains unchanged in all of the views. The cylinder l is a casting and is cored to form the mixingchamber 2, which is largest at its center. The internal shoulder 3 is formed at the upper end of the cylinder 1 and supports the amescreen. As seen from the inside or looking downwardly, there is a band around the mixing-chamber, and the shoulder 3 is the upper end of this band. The slits 4 are cut vertically from the upper end of the cylinder 1 and form gas-openings leading from the mixing-chamber through the band. Recesses 5 are formed in the outer surface of the cylinder below the plane of the shoulder 3, and the slits 4 communicate with said recesses. The Vertical ribs 6 separate the recesses. The bead 7 forms a shoulder to support the chimney frame or gallery, and the vertical portion 8, extending from the bead 7 to the recesses 5, fits within the band of the gallery. Below the bead 7 the portion 9 of the cylinder is contracted in size.

In Fig. I the nipple 10 is formed integral with the lower end of the cylinder 1 and is internally screw-threaded to be attached to the supply-pipe. The arm 11 extends downwardly from the nipple 10 to a position below the cylinder 1, said arm being inclined substantially at an angle of forty-fivedegrees, and a Valve-casing l2 is formed upon the lower end of the arm 11. The arm 11 is drilledto form the passage 13, which leads tally.

from the supply-pipe to the Valve 12. The eye 14 is formed integral with the arm l1 and is designed to receive the hook on the end of the alcohol-torch. The valve 12 discharges into the mixing --chamber 2, and the' gas formed within the mixing-chamber leads upwardly, and a portion of the gas passes outwardly through the slits 4 and burns within the recesses 5. The mantle is lowered to a position around the recesses 5, and the subflames in the recesses 5 are within the mantle, thus serving the double purpose af assisting in heating the mantle and heating the metal of the cylinder l very hot, said metal serving as a conductor to lead the heat downwardly to the gasolene within the nipple 10 and the arm 11. The subtlames within the' recesses 5 are below the flame-screen, which rests upon the shoulder 3, and within the mantle I prefer to form the gas-openings leading to the recesses 5 by using slits 4, as shown in Figs. I, II, III, and V; but these gas-openings may be formed by boring holes 15, as shown in Fig. VI, said holes being formed through the metal between the ribs 6. Any means by which gas is led to the recesses 5 will serve the purpose.

In Fig. II the pipe 16 is screwed iutothe nipple 10. The horizontal arm 17 leads from the lower end of the pipe 16 to a position below the mixing-chamber, and the valve-casing 12 is formed integral with the arm 17. This construction is equivalent to the construction shown in Fig. I, the only difference being the screw-threaded connection.

In Fig. III the lower end of the cylinder 1 is attached to the valve-casing 12 and has airopenings 18 formed through its wall horizon- The nipples 19 and 2O extend in opposite directions from the valve-casings 12 and are designed to receive the supply-pipes. The eye 14 is formed integral with the valvecasing and one of the nipples. The drop-cup 21 is formed integral with the stuffing-box 22 of the valve-casing 12.

The principal feature of my invention is the cylinder 1, cored to form the mixingchamber 2 and having the recesses 5 in its outer surface below the plane of its Hamescreen and having gas-openings leading from the mixing-chamber through the wall of the cylinder 1 to the recesses 5, so that the gas IOO . the recesses directly against the metal of i the cylinder 1 by the flame above the amescreen; but a very little gas burning within the cylinder l and within the lower portion of the mantle will heat the cylinder l to a very high temperature, and thus the subflames being Within the mantle do not produce a waste of The ribs 6 serve as guides for the band of the gallery, the Outer face of said ribs being in alinement Wilh the Outer face of the portion 8, which rests within the band of the gallery, so that said band may be moved upwardly without danger of its being tipped and breaking the mantle Or tipping the chimney Off.

1. In a hydrocarbon-burner, a hollow cylinder forming a mixing-chamber, said chamber being enlarged at its center, and said cylinder having recesses in its outer surface, and Openings leading from the recesses tO the mixing-chamber, and there being vertical ribs between said recesses to guide the chimneyframe, substantially as specified.

2. In a hydrocarbon-burner, ahollow cylinder forming a mixing-chamber, said cylinder having recesses in its outer surface and gas-Openings leading through its Wall from the mixing-chamber to the recesses; there being vertical ribs between the recesses to guide the chimney-frame, and there being an enlargement below the recesses to su pport the chimney-frame, substantially as specified.

3. In a hydrocarbon-burner the hollow cylinder cored tO form a mixing-chamber, and having the recesses in its outer surface, and having the band on its inner surface opposite the said recesses, and having openings leading through its wall from the recesses to the mixing-chamber, and having the bead below the recesses, substantially as specified.

4. In a hydrocarbon-burner a hollow cylinder forming a mixing-chamber, and having recesses in its Outer surface, and having a band on its inner surface Opposite the said recesses and having gas-openings leading through its wall from the recesses to the mixing-cham ber, and having an enlargement below the recesses to support the chimneyframe, substantially as specified.

5. In a hydrocarbon-burner a hollow cylinder forming a mixing-chamber, and having recesses on its outer surface, and having a band on its inner surface Opposite the said recesses, and having gas-Openings leading through its wall from the recesses tO the mixing-chamber, substantially as speciiied.

6. In a hydrocarbon-burner a hollow cylinder forminga mixing-chamber, and having recesses in its outer surface, and having a band on its inner surface Opposite the said recesses, and having vertical gas-Openings leading through its Wall and the said band, from the recesses to the mixing-chamber, substantially as specified.
