HAROLD J. BELL, OF GLOUCESTER CITY, NEIV JERSEY, ASSIGNOE TO THE WELSBACH INCANDESCENT GAS LIGHT COMPANY, OF NEW JERSEY.

INCANDESCENT GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 400,169, dated March 26, 1889.

Application filed June 21, 1888. Serial No. 277,713. (No model.)

To all whom, it may concern;

Be it known that I, HAROLD J. BELL, a citizen of the United States, residing at Gloucester City, in the county of Camden and State of New Jersey, have invented new and useful Improvement-s in Incandescent Gas-Burners, of which the following is a specification.

My invention consists in an incandescent gas-burn er comprising an atmospheric gastube, a vertically-adjustable shield carrying an internally and downwardly projecting tube or sleeve to control the lateral air-inlets of the atmospheric gas-tube, and a combined burner and gallery supported on said shield.

The invention will be described in detail, and then particularly pointed out in the claims.

In the annexed drawings, Figure 1 is a vertical section of my improved incandescent gasburner. Fig. 2 is a perspective view of the adjustable shield, partly broken away. Fig. 3 is an elevation of the atmospheric gas-tube and attached base.

The numeral 1 designates a thimble or burner-base which is internally threaded for attachment to a gas-fixture and externally threaded for engaging a wire nut or spiral ring, 2, supported in the lower enlarged portion of a bell-shaped shield, 3, which is thus made vertically adjustable.

In the upper end of the thimble 1 is a thin perforated metal disk or diaphragm, 4, and above this disk is supported the atmospheric gas-tube 5, having lateral air-inlets 6, as usual.

A vertical tube or sleeve, '7, is secured by brazing, soldering, or otherwise in the upper contracted portion or neck of the shield 3 in such a manner that about one half of the tube 7 projects above the shield and around the upper end of the atmospheric gas-tube 5,while the other half of said tube projects down within the shield in position to control the internal portion of the sleeve or tube '7 to control the entrance of air through the inlets 6 of the atmospheric gas-tube.

On the shield 3, as shown in Fig. 1, is loosely supported a combined burner-tube, 9, and gallery 10, said burner-tube and gallery being independent of the shield, so as to be easily removable therefrom vertically without disturbing the position of said shield upon the burner-base and without interfering in any way with its adjustment. If desired, however, the shield, burner-tube, and gallery may be rigidly connected or formed integral with each other.

The burner-tube 9 is provided internally with a bead or shoulder, 11, for supporting a convex wire-gauze diaphragm, 12, which is arranged above the atmospheric gas tube and shield. This burner-tube 9 also supports a. burner-tip, 13, of any suitable construction.

The gallery-shell 10 is formed with a bead, shoulder, or groove, 14, to receive the flanged lower end of an annular deflector, 15, which is thus supported about midway between the 7 5 gallery and burner-tube.

The interior of the deflector 15 is intended to receive the skirt or lower portion of a man= tle or.similar incandescent device suspended from a rod that may be supported in a socket, 8o 16, by means of a set-screw, 17, as usual. The flange 18 on the lower end of the deflector will serve to support a chimney, and this flange, as well as the gallery=shield, is suitably perforated for the passage of air.

The operation of the burner will be readily understood, and it will be seen that by means of the shield 3 and its attached tube 7, sur= roundin the atmospheric gas-tube, the quan* tity of air admitted to the burner can he eats o ily and conveniently controlled.

I would have it understood that I do not herein claim the combination of an atmos= pheric gas-tube, a vertically adjustable bell= shaped shield movably supported on the base 9 5 of said tube, and a vertically adjustable burner-tube supported on the shield and movable therewith to cover and uncover the lateral air-inlets of the atmospheric gas-tube, as such are described and claimed in Letters Patent No. 396,256, granted to me January 15, 1889, while by my present invention the lateral air inlets of the atmospheric gas-tube are not controlled by a vertically-adjustable burner-tube, but by a tube or sleeve, '7, projecting downward within the adjustable shield.

hat I claim as my invention is 1. In an incandescent gas-buri'ier, the combination of an atmospheric gas-tube, a verticall y-adj u stal ile bell-shaped shield carrying a tube or sleeve that projects downward within said shield to control the lateral air-inlets of the atmospheric gas-tube, and a combined burner and gallery supported on said shield, substantially as described.

2. The combination, with the externallyscrew-threaded base 1. and atmospheric gastube 5, of the bell-shaped shield 3, having an internal spiral ring or wire nut, 2, and carrying the tube or sleeve 7, having its lower end projecting downward within said sleeve, substantially as described.

3.- ihe combination, with the atmospheric gas-tube 5 and vertically-adjustable shield 3, having a downward-projecting sleeve, 7, of the combined gallery and burner supported on said shield and comprising tube 9, galleryshell 10, burner 13, and deflector 15, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

I'IAROLD J. BELL.
