GAS-LIGHT BURNER. i i

Application filed February 14, 1922. Serial 1T0. 536,462.

To all whom it may concern Be it known that I, FRANCIS DnGnUcHY, a citizen of the United; States, and a resident of Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Gas-Light Burners,

of which the following is a specification.

This invention relates in. general to gase ous fuel burners for lighting purposes, and

more particularly to a gas-light burner of the flame type including a' tip for spread ing the flame for illuminating purposes. v The Ob]GCtS of the invention areto provide an illuminatingburner of the character described embodying novel features of construction whereby lightof high quality is obtained; to provide a construction for an illuminating burner of this character which produces substantially complete combustion of the gaseous fuel and thereby a white, brilliantflame *3to thus )rovidea burner includ- I I ing a pair of spaced gas outletsand improved means for d recting a current of air between said outlets into the flame; to pr0-.

vide a burner including a body portion adapted to be connected to a gas pipe and having a pair of spaced gas outlets directed upwardly and inwardly toward each other whereby the flames from said outlets merge into each other, said body portion having opposite grooves therein beneath and between said outlets whereby the heat from said flames. draws air upwardly through said grooves into said flames; and to obtain other results and advantages as may be liigure 2 is a partial. transverse vertical.

sectional view and side elevation of the burner, and

lligure 2) is a top plan view thereof. In the embodiment of the invention shown on the drawings the reference character A designates the body portion of the burner which includes a. tubular portion 1 interiorly threaded at one end thereof, (as at 2. for attachment to a gas-pipe or the like, the

other end of said tubular portion communieating through an opening 3 with a chamberA, which is formed at the end thereof with an upstanding burner tip supporting projection 5; The projection 5 is provided with a parrot spaced passages 6 communicatingwith the chamber. 4 and converging upwardly toward each other, a burner tip 7 being mounted at theouter end of each of said passages 6, and the outlet slits 8; of said tips 7 being arranged substantially parallel with each other and transversely of the projection'ii. The projection 5 is also provided in oppositesides thereof between the burner" tips? with substantially parallel grooves 9 whichopen through the-top of the projecti'on and are separated by a wall. 10 terminating short of the upper end. of the proection 5, as clearly shown in Figure 2 said grooves being disposed longitudinally-of the projection 5 and substantially in the plane bisecting theangle formed by the converg 'ance of the burner outlets.

With this construction when the burner is attached to a gas-pipe or the like, the gas turned on and ignited at the tips 7,-the

flames B frointlie tips will merge into each other, as .clearly shown-1n Figure ,1, dueto the converging of the passages 6 and tips 7.

The heat from the flames B will cause a circulation of a current of air upwardly through each of the grooves 9 into the space between the flames B, as indicated the arrows in Figure 2, and this air enteriiig the flaincswill cause a substantially complete combustion of the gas leaving the tips 7. The currents of air rising through the two grooves 9 will, when they reach the top of the wall 10, impact with each other so as to spread substantially in the plane bisecting said angle of convergence of the burner tips and upwardly into the flames. This complete combustion of the gas makes the flames B substantially white in color,

brilliant and of a quality and 'quantity favorably comparable with the light produced by. the well-known incandescent :DJZLIItlOS. I have found that by varying the depth of the grooves 9 the width of the flames B can be varied, and that different shaped tops on the wall 10 will produce different shapes of flames. Thus, an in crease in the depth of the grooves 9 will. produce a wider flame, and a square top on the wall 10 will produce substantially a square flame. I

A plurality of superposed layers of fine mesh wire fabric 11 are preferably arranged in the tubular portion 1 of the burner between the gas-pipe andthe chambers so.

as to filter the gas and provide a uniform.

possible embodiment of my invention, it will be understood that this is only for the purpose of illustrating the principles thereof, and that many modifications and changes can be made in the detailvconstructionhof the gas burner without departing from the spirit or scope of the invention. Therefore, I do not desire to be understood as limiting myself except as required by the following claims when: construed in the light of the prior art.

Having thus described the invention, what- I claim is:

1. A gas-light burner including a body by the heat from said flame draws a current of air upwardly through each of said grooves into the space between said burner outlets where said currents impact with each other and spread into said flames.

2. A gas-light burner including a body portion having a pair of spaced converg 1;: burner outlets the flames from which merge together. said body portion being provided at opposite sides thereof between said burner outlets with substantially parallel grooves disposed substantially in the plane bisecting the angle formed by the convergence of said outlets and opening through the top otsaid body portion, said grooves being separated by a wall terminating short of the top of the said body port-ion, whereby the heat from said-flames draws a current of air upwardly through each of said grooves over the top of said wall where said currents of air, impact with each other and are caused to spread substantially in said plane bisectingthe angle 01" con-vergance of the burner outlets and upwardly into said flames.
