My invention relates to gas burners and more particularly to the type of burners employed in making carbon black.

The principal object of my invention is to produce a burner from whichthe maximum yield of carbon per unit of natural gas is obtained.

(lther and further objects of the invention will be in part described and in part specification is proceeded with:

Tn the accompanying drawings:

Figure l is a side View of the burner,-

ig. 2 is a longitudinal sectional View through the burner;

Fig. 3 is a section on the line 3-3 Fig. i;

Fig. 4. is .1 section on the line H Fig. 1;

lg. 5 is a section on the line 55 Fig. i;

Fig. 6 is a section on the line 66 Fig. i;

Fig. 7 is a view similar to Fig. l, but showing the shell or burner in dotted lines.

Referring more particularly to the drawings 1 denotes the burner comprising a shell 2 of brass or like-suitable metal. The inlet end of the shell is open and preferably screw threaded externally as at 3 to facilitate attachment to a gas supply pipe (not shown). The opposite end or tip of the shell or burner is formed with a small opening or perforation a communicating with a large counter bore 5 of concave shape, the purpose of which will presently be described. An iron wire or stamping 6 is coiled around the burner and has its free end 7 overlying the tip of the burner and in line with the opening at therein, for a purpose also to be explained hereinafter.

A small disk shaped screen 8 preferably of copper, is inserted in the shell 2, in position to cover the opening 4:. The shell is then partially tilled with refractory material 9, such as pebbles, -taclrs, scraps of metal, ore or the like, and a second screen- 10 similar to the screen 8 is inserted in the open end of the shell to hold the refractory material in place. This screen 10 is in turn held in place by a metal collar ll adapted tlpecitication of Letters Patent.

to fit snugly within the screw threaded portron oil the shell.

Tn operation the threaded portion the gas inlet end of the burner is connected to any suitable source of natural gas'supply. The gas passing through the screens 8 and i0 and refractory material. 9 is broken Alter the burner has been lighted for a short time, the heat from its own tlame heats the burner and likewise the refractory material contained therein. This has a tendency to pro-heat the gas before it is ready for combustion. it also. has a tendency to purity. The counter bore at tip of the burner spreads the flame at its source, giving the flame a steadier column.

The flame then strikes the iron wire at its source. This either exerts a catal tic action or a mechanical action, but in either event it produces the following results. The combustionproce'eds in such a manner as to destroy or radiate away the blue envelop of the flame, allowing only the red or carbon bearing flame to come in contact with the metal plate (not shown) under which it is being burned thus increasing the yield of carbon per unit of natural gas. T have found that the iron wire 6 will not function properly unless the tip oil the burner is counter bored as shown.

Having thus described my invention, what I T claim is:

L A gas burner comprising ashell open at one end for connection with a source of gas supply, the other end of said shell beingv prorided with a counter bore and an aperture communicating with said counter bore, a wire screen closing said "aperture, refractory material in said shell, a second wire screen closing said open end and holding said refractory material in place and a wire coiled around'said shell at one end and having its other end overlying the tip of said burner in line with said aperture.

2 A gas burner comprising a shell open at one end for connection with a source of gas supply, the other end of said shell hava restricted outlet opening, means in said shell. for atomjzing the gas pa therethrough, and a member secured to said burner havmga portion thereof in line with said restricted outlet opening.
