INCAN DE SCENT GAS-BURNER.

SPECIFICATION formingpart of Letters Patent No. 760,930, dated May 24, 1904.

7 Application filed February 3,1904. Serial No. 191,882. (No model.)

To a whom it may concern:

Be it known that I, ALFRED J ABEZ SIMPsoN, Jr., a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented new and useful Improvements in Incandescent Gas-Burners, of which the following is a specification.

This invention relates 'to incandescent gasburners; and theprimary object of the same is to provide a burner for Welsbach andother incandescent lights with efficient and reliable means for proportionately regulating the sup-- ing the best result may be effected without requiring ail-adjustment of independent mechanism or devices.

A further object of the invention is to prevent smutching or blackening of the mantle of the burner by an irregular or improper admixture ofair and gas and also to cause the air to enter the mixing-chamber behindthe gasand prevent the burner fromlighting back at the point where the gas enters the mixingchamber.

A further object is to incorporate in a burner organization a series of coacting elements for rendering the burner more practical and including valve devices connected for simultaneous operation, so that when one is opened to admit gas to the burner the other will be closed to prevent the escape of the gas through a pilot-burner, and vice versa.

With these and other objects and ad vantages in view the invention consists in the construction and arrangement of the several parts,

which will be more fully hereinafter set forth.

In the drawings, Figure 1 is a side elevation of a burner embodying the features of the invention and showing a mantle and part of a chimney applied thereto in dotted lines. Fig. 2 is a transverse vertical section through the burner. Fig. 3 is a transverse vertical section .through a portion of the burner in a plane at right angles to that shown by Fig. 2. Fig. 4 is a horizontal section on the line 4 4:, Fig. 3. I Similar numerals of reference are employed to indicate corresponding parts in the several views.

The numeral 1 designates a gas-inlet plug or coupling bored axially for the passage of gas therethrough and having a screw-threaded terminal for securing the same to a gas-feeding. means or supply. The plug or coupling 1 communicates with a tubular T-head 2, havenlargements at opposite sides of the point of communication therewith of the plug or coupling to form valve- seats 3 and 4, the valve-seat 3 being materially larger than the seat 4, and said seats respectively having mounted thereinrotatable valves 5 and 6. The valve 5, as shown, has a passage 7 out therethrough at one side of the center and opening out through the periphery thereof, said passage being straight through the valve, and the valve 6 is formed with an arcuate passage 8, opening through its periphery.

The T-head at opposite ends is provided with upwardly-projecting coupling-nipples 9 and 10, the nipple 9 being materially larger-than the nipple 10 and having a bore therethrough of the same; dimensions as the bore of the plug or coupling 1 and the head 2. The bore of' the nipple 10 is reduced proportionately to the bore through a pilot-burner tube 11 which is attached to said nipple and extends upan operating-lever 13, the end of said lever adjacent to the stem 12'being enlarged and formed with a segmental slot 14," in which a projection 15, eccentrically held by an exterior head 16, connected to the valve 6, loosely projects, the parts being so proportioned that when the lever 13 is operated to open the valve 5 the valve 6 is closed, as shown by Fig. 2. When the lever 13 is operated in a reverse direction to close the valve 5, the valve 3 is opened, the passage 8 in the latter valve being of such length that the gas will be permitted to pass therethrough into the pilotburner tube 11 before the gas has been fully shut off from the burner proper by the valve 5 in order that the pilot-burner may become ignited and so remain until the burner proper is to be used. The end of the lever 13 opposite that having the segmental slot 14 therein is adapted to have a suitable pull-rod or other analogous device attached thereto, and, as in ordinary constructions of this kind, the pull device may depend from the burner any distance desired.

A burner 17 of any approved type to cooperate with an incandescent mantle is used in the present instance and is embraced by a clasp 18, secured to the upper part of the tube 11. This burner has a chimney-supporting rim 19 depending therefrom and an applyingtube 20, which is snugly fitted over a Bunsen tube 21, extending upwardly from the center of an enlargement or mixing-chamber 22 at the lower extremity thereof.

cumferentially reduced between its opposite ends to form an air-receiving chamber 24, the shell of the chamber 22 being secured to the lower end of the plug by screw-threads, as'clearly shown by Figs. '2 and 3. The upper end or head of the plug 23 is reduced to form a partition disk or flange 25, having a.

series of openings'26 extendingvertically therethrough in circular alinement around the center of said partition. The shell of the chamber 22, below the position of the partition 25,'is increased in thickness and has a plurality of reduced openings 27 formed therein to provide air-inlets, the air passing through the openings 27 into the chamber 24 and then upwardly through the openings 26 into the.

threaded, as at 31, and adjustably fitted in the stem and projecting through the plug is a needle-valve 32, having a right-hand screw enlargement 33, engaging the threads 31, and a lower increased left-hand screw enlargement 34, the lower end of the needle-valve being provided with a milled head 35, which is readily accessible for adjusting the valve above the T-head 2. Communicating with the stem 28 above the upper terminal of the threads 31 is a feed-pipe 36, having a screwplug 37 in its outer end for cleaning purposes and a depending coupling-nipple 38 to receive the upper end of a connecting-pipe 39,

A plug 23 is projected upwardly into the chamber 22 through the lower end of the latter and is cir-' The lower part of the bore through the stem 28 is Screwwlhich is attached at its lower end to the nipp e 9.

Projecting outwardly from the stem 38 at a point slightly below the lower end or head of the plug 23 are diametrically-opposed guidearms 40, having vertical openings 41 extending through their outer ends, in' which sliderods 42 have movement and'are secured at their lower ends to the opposite extremities of a yoke 43, which engages the left-hand screw enlargement 34 of the needle-valve. The upper ends of the slide-rods 42 are secured in sockets 44 at diametrically opposite points on a controlling-sleeve 45, slidable over the exterior of the lower extremity of the shell of the mixing-chamber 22 and adapted to regulate the open and closed condition of the air-inlet openings 27. By turning the needle-valve 32 in opposite directions it will be adjusted'to admit more or less gas into the mixing-chamber 22 when the valve 5 is open, and simultaneously with this adjustment of the needlevalve the controlling-sleeve 45 will be moved to regulate a proportionate admission of air into the air-receiving chamber 24. The advantage of this unity of adjustment and control of the admission of air and gas is that the right proportions of both air and gas will be at all times admitted to the mixing-chamber 22, it being understood that in the preliminary arrangement of the parts the sleeve 45 and needle-valve will be positionedto obtain a proper admixture of air and gas. Another advantage resident in this simultaneous and proportionate adjustment is the absolute impossibility of admitting more air than necessary and retarding complete combustion and a consequent smutching or blackening ofthe mantle. By having the gas enter the mixing-chamber ahead of the air ignition of the gas in the mixing-chamber or lighting back is prevented. Furthermore, the adjustment of the needle-valve and the admission of air may be carried on without modifying the How of gas to the stem 28. i

The improved burner will be found exceptionally advantageous in use and more economical in the use of gas and mantles.

Itwill be understood that changes in the proportions, dimensions, and minor details may be resorted to without departing from thespirit of the invention.
