HANS O. HANSON, OF ALBERT LEA, MINNESOTA.

IN VERTED GAS-B URNER.

Specification of Letters Patent.

Patented July 30, 1907,

. Application filed May 10,1906. fierial No. 316,178.

To all whom it may concern:

Be it known that I, HANs C. HANSON, a citizen of the United States, residing at Albert Lea, in thecounty ol' Freeborn and State of Minnesota, have invented certain new and useful Improvements in Inverted Gas-Burners; and I do declare the following to be a lull, clear, and exact description 01' the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in inverted gas burners, of that class in which a mixture of air and gas is burned in an inverted mantle.

The object of the invention is to improve and simplify the construction and operation of burners of this character, and thereby render the same more eflicient and at the same time less expensive.

With the above and other objects in view, the inventionconsists in certain novel features of construction, combination and arrangement of devices as hereinal'ter described and claimed.

In the accompanying drawings,Figure 1 is a side elevation of my improved inverted gas burner, the globe being shown in section; Fig. 2 is a vertical sectional view through the same; Fig. 3 is a horizontal sectional view, taken on the plane indicated by the line 3-3 in Fig. 1, and looking upwardly in the direction of the arrow; Figs. 4 and 5 are detail views of the devices for supporting the gas mantle; and Fig. 6 .is a detail view through the valve.

Referring to the drawings, 1 denotes my improved inverted gas burner, which is screwed or removably secured upon a depending supply pipe 2, through which a mixture of air and gas is supplied to the burner. This pipe 2 has in its threaded lower end a thin wire gauze screen or partition 3, Fig. 2, which is concave in form and provided for the purpose of preventing the flame from flashing up into the pipe. The burner comprises a valve casing section 4 and a burner tube section 5, which parts have a screwthreaded connection, the upper end of the valve easing 4 being secured upon the lower end of the pipe 2. The valve casing has a'bored seat 6, which is disposed transversely and of substantially cylindrical form to receive a similar shaped plug valve 7. The latter is formed with a transverse opening which is adapted to be turned into and out of alinement with the passage through the valve casing for the purpose of turning on and oil the supply of Said valve has upon its projecting outer end an enlargement through which is passed and in which is secured a cross-bar or lever 8. Chains or similar flexible connections 9 are hung from the outer ends of this crossbar or lever, so that I by drawing upon one of them the valve may be retated to its open position, and by drawing upon the other, it may be turned to its closed position, as may I be readily understood. Upon the lower end of the burner tube 5 is secured a tubular or cylindrical enlargement or head 1]., in the lower end of which is secured by means of a cross-pin 12 a central headed core 13 and an annular filling 14 consisting of a straight metal strip and a corrugated metal strip wound upon the core between the head or lower end and the crosspin 12, as clearly shown in Figs. 2 and 3 of the drawings. This open-work fillingl l serves to prevent the flame from passing up into the burner tube 5, to spread and distribute the gas discharged through it, and also to superheat the same since it becomes intensely hot from the heat 15. This mantle is attached to a cylindrical holder 16, which is detachably engaged with a hanger or support 17, secured upon the burner tube immediately above the enlargement or head 11. This hanger 17 comprises a spider, from which depends an annular flange termed at diametrically opposite points with bayonet slots 18 to receive outwardly bent tongues or projections 19 formed on the mantle holder 16. This construction permits the latter to be readily applied to and removed from the burner. A globe 19 of any suitable form and construction is supported from the burner tube by means of a hanger, which comprises a spider 20 adjustable upon the tube 5 by a setscrew 21, and having secured upon the depending outer ends of its arms by means of set-screws 22, an annular band or ring 23. The rim of the globe 19 is secured within the band or ring 23 by the set-screw shown in Figv 3.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing .irom the principle or sacrificing any of the advantages of the invention, as defined by the appended claims.

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

In an inverted gas burner, a supply pipe, a valve casing secured thereto, provided with a valve, a burner tube depending from said casing, a cylindrical head on the lower end of the tube, a headed core and a cross pin for securing it in the lower end of said head, an open annular filling in the lower end of said tube between the head of the core and the cross pin, a cylindrical hang-er mounted upon the tube above said head, and a cylindrical mantle holder detachably secured to the hanger in position to hold an inverted mantle below the lower end of said tube.

In testimony whereof I have hereunto set my hand in presence of two subscribingwitnesses.
