THEODORE GLOUGH, OF DOBBS FERRY, NE\V YORK.

GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 314,653, dated March 31, 1865.

Application filed July 23, 1884.

(No model.)

To all whom it may concern:

Be it known that I, THEODORE OLoUGH, of Dobbs Ferry, in the county of W'estchester and State of New York, have invented certain Improvements in Gas-Burners, of which the following is a specification.

The flame of the ordinary bat-wing burner is objectionable from its liability to form sharp corners or projecting points at its upper lateral portions. This has been in a measure modified by the well-known excavated lava tip, but with this the flame is of greater thickness than is desirable, and such tips are not of uniform character because the internal excavation of each must be made with a hooked tool and under conditions which prevent the excavations of any number of the tips from being exact duplicates of each other, this producing a corresponding variation in the flames and a more orless imperfect result as relates to obviating the sharp corners or points aforesaid.

The object of this invention is to provide a tip for gas'burners which will insure a thin flame of the modified bat-wing type aforesaid, entirely devoid of the objectionable acute corners, and which, while affording superior advantages in this respect will be capable of more economical manufacture, and of more uniform excellence than the most approved burners heretofore in use, and of which any number may be made exact duplicates of each other, owing to simplicity of structure and convenience of manufacture.

My said invention is more particularly designed for air-gas, so termed-that is to say, for gas formed of atmospheric air charged with hydrocarbon vapors; but it may also be employed with excellent results with common illuminating-gas.

My invention may be embodied either in a separable tip or it may be embodied in a tip integral with the body or main portions of the burner.

My invention comprises a tip or burner of novel construction, whereby the advantages hereinbefore indicated are effectually secured.

The drawings are on a scale of about four times the dimensions of the burner as I ordinarily apply the same to use; but the burner may, of course, be made of any size desired.

Figure 1 is a central vertical longitudinal sectional view showing my invention as applied in a separable tip, and Fig. 2 is a side View of such burner. Fig. 3 is a central longitudinal sectional view showing my said invention as formed integrally with the body as a non-separable tip of a burner; and Fig. 4 is a side view of the inner portion of such burner, the external part being shown as broken away,the better to show the tip integral with the body.

A is the tip, and whether made separable,as in Figs. 1 and 2, or integral with the body of the burner, as in Figs. 3 and 4, is formed as follows: The chamber or bore a is of cylindrical or substantially cylindrical form, and with vertically straight sides from the bottom a to the base of a shoulder, b. The domed upper part, c, of the interior of the tip A springs from the inner upper edge of this shoulder, as shown more fully in Figs. 1 and 3. The shoulder itself, with reference tothe straight vertical sides of the tip, has an angle of about forty-five degrees. Thevariance from this angle, if any, should be but slight, as any material departure from this angle will in some measure detract from the efiiciency of my said invention. I do not, however, limit myself strictly to said angle. The slit f of the tip is extended downward at the opposite sides of the tip to a point belowv the base of the shoulder. This collocation of the chamber or bore a, the shoulder b sloping with reference to or at an angle to the sides of said chamber, the domed top of the interior of the tip, and the slit extended below the said shoulder insure a retardation of the outer portions of the column of gas ascending through the burner, so proportioned and distributed that, as I have fully determined by actual and practical trial,the flame of the gas issuing from the burner, assumes a "symmetrical form devoid of the acute corners, which, as hereinbefore explained, occur with the flame of an ordinary burner of the bat-wing type, the flame being also thinner than that of the excavated tip. By my invention therefore I am enabled to secure all'the advantages of the excavated tip with none of its disadvantages, and with the added excellence of a thinner flame.

It is of course to be undertsood that the body B of the burner may be of any suitable character or construction. As shown in the drawings, the central tube, A, may communicate with a concentric open-top chamber,'B, by 5 means of an orifice, g,which on occasion may be closed or may be regulated as to available area by a screw-valve, C; but my invention may be applied with advantage in connection with a body devoid of such concentric cham- 10 her or of any other suitable construction.

What I claim as my invention is A gas-burner tip constructed with the angular orsloping shoulder 12 between the bore or chamber a and the domed portion c,and with the slitf extended below said shoulder, all 15 substantially as and for the purpose herein set forth.

THEODORE GLOUGH.
