BURNER FOR BURNING RICH GASES, ESPECIALLY ACETYLENE GAS.

SPECIFICATION forming part of Letters Patent No. 596,144, dated December 28, 1897.

Application filed April 29, 189 '7.

To ail whom it may concern;

Be it known that I, EDWARD J. DOLAN, of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Burners for Burning Rich Gases, especially Acetylene Gas, of which the following is a full, true, and exact description, reference being had to the accompanying drawings.

This invention relates to an improved burner for burning gases rich in hydrocarbon, and especially for burning acetylene gas, its object being to produce practically a smokeless flame and a burner which in practice will not become choked or clogged by deposited carbon. In accomplishing this result I mingle or surround the gas to be consumed with a suitable amount of air before such gas is brought to the kindling temperature or point of combustion.

In the class of burners in which two jets of gas are caused to impinge against each other a limitation in the size of the flame arises by reason of the fact that, as ordinarily con structed, an excess of escaping gas produces an irregular or smoky flame, especially when acetylene gas is burned. If the angle of the jets to each other is acute, this limitation is met earlier than when the angle of the jets approaches parallelism, but in the latter case there is a downward body or fold of the flame produced which prevents the proper formation of the flame and produces irregularity and smoke.

By my present invention I have added to the two previously-known jets, inclined toward each other at an angle, a third jet which meets these two at or about their point of intersection and forces the flame upward and thereby prevents the formation of the fold to which I have above referred.

My invention will be readily understood from the accompanying drawings, in which similar letters of reference refer to similar parts, and in which Figure 1 represents a vertical elevation of my improved burner in part broken away; Fig. 2, a vertical section at right angles to Fig. l, and Fig. 3 a plan of my improved burner.

Serial No. 634,376. (No model.)

A represents the ordinary pillar, and B the burner-block. This block may be made of any of the materials ordinarily employed for making gas-burners. It is provided with two small gas jets or channels 0, inclined at such angle to each other as that these jets meet in the cup shaped chamber D. An annular channel E encircles the burner-block and is pierced by the burner-orifices O. The burnerorifices are bored out to larger diameter, as at F, beyond the annular channel E, and air surrounds the gas passing through the channels F, but the flame is not formed until the gas and air escape into the cup D. A

V vertical channel G is cut through the burnerblock and enters at the bottom of a horizontal channel H,which intersects the cup-shaped opening D, as plainly shown in Figs. 2 and 3. This channel furnishes an air-supply to the gas passing upward through the channel G before it meets the intersecting gas-jets escaping from the tubular openings F F. The effect of this third jet is to force upward the intersecting gas-jets. This therefore enables me to burn in this burner a much larger amount of acetylene'gas than would be the case if the third vertical jet was not employed.

The operation of this burner is to cause to meet at the same point three jets of gas and each of, those jets is itself surrounded and partly mingled with air before reaching the point of combustion. For some purposes this air-mixing device is not essential.

In practical operation this burner produces a regularly-shaped flame, without smoke and without clogging, and it can burn a muchlarger volume of acetylene gas under these conditions than the burners at present in use.

It is obvious that my invention may be in part utilized without the third jet.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination in a gas-burner of two jets inclined toward each other and meeting at the point of combustion, and a third jet located in the same plane as the first two jets, in the bottom of a slot at right angles to the plane of said two jets, said third jet intersecting them at their point of junction, each of said jets being provided with an independent air-mixer bringing air in contact with the gas before reaching the point of combustion, substantially as described.

2. The combination in a burner of two jets inclined toward each other and located in the same burner-block with an air-mixing device connecting with each of said jets, substantially as described.

3. The combination of the two jets 0 0,10- cated in the burner-block B, and the air-mixing openings E E, cut in said block, substantially as described.

4. The combination of the two jets O C, located in the burner-block B, with the converging channels F F, carrying the mingled gas and air toward the point of combustion, substantially as described.

5. The combination in the same burnerblock of two inclined gas-channels C O, the
