GAS-BURNER.

Specification of Letters Patent.

Patented July 3, 191 '7.

Application filed March 2, 1916. Serial No. 81,577.

T 0 all whom it may concern.

Be it known that I, FRANK W. GAULT, J r., a citizen of the United States, residing at ()kolona, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention relates to gas burners of the class used in various arts to produce intense degrees of heat.

An object is to provide a burner wherewith the character of the flame may be arranged to suit varying conditions of service, which will be economical in the consumption of gas, which may be cheaply constructed and which will be durable in service.

With the foregoing and other objects in view, the invention consists of the novel construction and arrangement of parts illustrated in the accompanying drawing, which forms a part of this specification, wherein is set forth an embodiment of the invention, but it is to be understood that such changes and modifications may be resorted to as come within the scope of the appended claims.

Referring to the drawings, wherein similar reference characters designate like parts in the several views, Figure 1, is a side elevation of an embodiment, of the invention; Fig. 2, a longitudinal section of same, on

line 2-2 of Fig. 3; Fig. 3, a transverse section on line 33 of Fig. 2; Figs. 4, 5, and 6, 7 and 8, 9, perspective views and central vertical sections, respectively of modified forms of burner-plugs; Figs. 10, and 11,

.central longitudinal sections showing modifled burner-plugs in position.

Referring now more in detail to the drawing, the reference character 1-- designates the burner proper, which comprises an induction tube, or supply pipe 2, which may be connected to a suitable mixer wherein air under suitable pressure is mixed with gas in suitable proportions; secured on the forward end of the induction tube is a hood -3, which may be of such dimensions as the circumstances require, and a burner-plug l-, a preferred form of which is substantia-lly quadrangular in cross section with screw threads on the corners thereof. The burner-plug maybe positioned in the end of the induction tube as shown in Figs. 2, 3, and 10, or it may be positioned in the neck 5- 0f the hood, as shown in Fig. 11. The burner-plug is provided with suitable means,

I such as screw threads -6'adapted to be engaged with internal screw threads 7 in the tube, and with a plurality of facets 8, said facets being arranged either parallel with the axis of the plug, as shown in Figs. 2 and 3, or at'an angle thereto as shown in Figs. 4 and 10. The presence of these facets form spaces 9 between the plugand the wall of the induction tube, through which the gas passes. The resulting flame being multilateral. If the facets are parallel with the axis of the plug, the resulting flame will be thrown straight forward forming a long slender flame. By inclining the facets the flame may be spread out in measure corresponding to the degree of inclination. A ledge, or projection-10 may be placed across the forward end of the facets, which while not of sufficient extent to deflect the flame, will impart thereto a fluttering or undulatory movement which increases the speed of propagation of the flame. In every installation of gas, for heating purposes, there are local conditions which require special character of flame to secure the greatest efliciency. My improved burner, lends itself most readily to the provision of flames with varied characteristics. The plug is of material, such as cast iron, which may readily be shaped, and by means of a suitable tool, such as a file, the angle of the facets may be changed, the height of the ledge 10, reduced, or its inclination across the facets altered (see Figs. 4, and 5). It may. be extended from each of the facets or only from certain ones of them, a shoul-.

der 11 may be square as shown in Fig. 4, or sloping as shown in Fig. 5. Each such change altering the shape of the flame and imparting thereto differing characterlstics.

The plug is provided with a central perforation, or passage, 12 which produces a round flame. The plug may be provided with an extension or tip 13 (see Flgs. 6, 7, and 10) provided with lateral slits, or openings 14, which extend outward from the central perforation, and having a passage 15 slightly larger in diameter than the width of, and extending diagonally across the slits from the upper edge thereof 'to the central passage. The corrugated, or

roughened surface of the induction pipe,

produced by the screw threads 7, assist in admixing the gas and air. The burnerplug may, for some purposes be provided with a plurality of peripheral recesses 16, the

rear walls of which are arranged at an angle to the axis of the plug. A plug of this construction may be reversed to serve with gas at either high or low pressure.

Having thus described my invention so that anyone skilled in the art pertaining thereto make and use the same, I claim:

1. In a gas burner, an interiorly screw threaded induction tube, a closed hood attached thereto, and a burner plug positioned in said tube, said plug having a plurality of facets extending longitudinally thereof with screw threads interposed between said facets.

2. In a gas burner, an internal screw threaded induction tube,.a closed hood attached thereto, and a burner plug positioned in said tube, said plug having a plurality of facets extending the length thereof, with screw threads between said facets, said facets being'arranged at an angle to the longitudinal axis of theplug. v

3. In a gas burner, an interiorly screw threaded induction tube, a closed hood attached thereto, a burner plug positioned in said tube, said plug having a plurality of facets extending the length thereof with screw threads between said facets adapted to be engaged in said tube, and a ledge, integral with the plug, disposed across the forward end of a certain of said facets.

4. In a gas burner an interiorly screw threaded induction tube, a closed hood attached thereto, and a multi-lateral plug provided with screw threads on' the angles thereof adapted to be engaged with the threads in said tube.

5. In a gas burneran interiorly screw threaded induction tube, a closed hood attached thereto, a burner plug positioned in said tube, said tube having a plurality of facets extending longitudinally thereof, said facets being disposed at an angle to the longitudinal axis of the plug, and a ledge on the plug disposed across the forward end of a certain of said facets. 1 p

6. In a gas burner, an induction tube, a hood, a multilateral burner-plug positioned 1n sa1d tube, and a tip on said plug, said plug and tip having a central passage therethrough and the tip having lateral slits extending outward from said central passage.

in said tube, the sides of said plug extending longitudinally of, and disposed at an angle to the axis thereof, a ledge disposed across the forward end of certain of said sides, and a tip on said plug, said plug and tip having a central passage therethrough,

the tip having lateral slits extending outward fro-m saidcentral passage.

9. A quadrangular burner plug provided with screw threads on the corners thereof, and having a central chamber extended into the body of the plug from the rear end thereof and having a restricted passage Il)eading through the plug from said cham- 10. A burner plug provided externally with screw threads, a portion of said screw threads being removed forming a plane surface which extends longitudinally vof the plug, the plug having a chamber extending into the body thereof from the rear end thereof and having a restricted passage leading from said chamber through the plug.

11. A burner plug having a chamber extended into the body from the rear end thereof and having a plurality of passages leading from said chamber through the plug, screw threads on the periphery of the plug, portion of said periphery being removed forming plane surfaces which lie in planes parallel with theaxis of the plug.
