FFICEG FRANCIS JARVIS PATTEN, OF NEW YORK, N. Y.

ACETYLENE-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 623,559, dated April 25, 1899.

Application filed April 16, 1898.

To (all whom, it may concern:

Be it known that I, FRANCIS JARVIS PAT- TEN, of the city of New York, in the State of New York, have invented a new and useful Improvement in Acetylene-Gas Burners, of which the followingis a full, clear, and exact description, reference being had to the accompanying drawings, in which Figure 1 represents a side elevation of the burner as it appears in use; and Fig. 2 represents a similar elevation, partly in section, the sectional part indicating the features of novelty I have introduced.

The chief difficulty with burners for acetylene gas appears to be to provide a sufficient, supplyof air to the flame to prevent smoking, especially when the flame is turned low, and, second, to insure a sufficiently complete combustion of the issuinggas at the point where it emerges from the Vent to prevent a deposit of soot or carbon at the opening of the vent, which clogs it up. The lines upon which it is generallyattempted to overcome these difficulties are to either supply an air-blast to the flame or to mix air with the gas just before it issues from the vent, thereby furnishing the necessary oxygen required for complete combustion, The plan I have adopted to produce the required flame is upon the first of these lines.

I am well aware that there is nothing essentially new about the general form of burner shown having two impinging jets or flames directed from the burner at an angle of about forty-five degrees to the horizon at each other and forming a single flat vertically-directed flame, this broad feature being common to many old types of burners. It is the arrangement of gas and air vents by which I obtain the desired result that constitutes the chief novelty of my invention, and this will be clearly understood by reference to the figures, in which like letters designate the same parts.

In both figures, S is the stem of the burner.

B and B are forked ducts leading to the fine gas-vents G G, which are preferably so inclined to each other in the same vertical plane that the issuing jets will proceed on lines at right angles to each other to a point in the central vertical axis of the burner,

Serial No. 677,777. (No model.)

where they unite to form a single vertical flat flame in a plane at right angles to the plane of the two jets.

The gas tips or vents G G, Fig. 2, are surrounded by a cylindrical jacket formed by a continuation of the tubes B and B as far as the ends of the gas-vents G G, and at three or more points in the circumference of the jacket its walls are perforated or bored through, so that the holes comejust at the base of the gasvents G G. These little orifices are indicated in both figures as A A, and there may be any number of them, depending on the quantity of air required for the flame.

The effect and operation are as follows: On lighting the gas the two jets are atlame clear down to the tips of the vents G G. This heats the tips clear down to their bases inside their inclosing jackets. The heated air thus formed in the jacket rises and in doing so draws after it more cold air from the outside through the air-passages A A. The escaping air from the jacket goes in the direction of the issuing jet into the flame, thus supplying it with a sort of continuous air-blast, providing the necessary oxygen to secure complete combustion, and so prevent smoking or sooty deposits even when'the flame is turned low.

I am aware that devices closely resembling mine have been used. In some the air is led into the gas tent or tip near the point of emergence and there mixed with the gas before it comes out, and there are devices in which a blast is sent against the flame from the outside; but this is done in a manner entirely different from that by which I insure a like resultnan1ely, the bell-shaped cup or jacket surrounding the gas-vent and forming an air-heating chamber.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is the following:

1. A burner for acetylene gas consisting of a gas-vent upon which the gas is ignited, and a jacket surrounding said vent, said jacket having inlets for the passage of air at or near its lower end, and an opening at the top for the delivery of the air to the ignited gas, substantially as described.

2. A burner for acetylene gas consisting of two gas-vents inclined toward each other and upon which the gas is ignited, and jackets surrounding said vents, said jackets each having inlets for the passage of air at or near its lower end, and being open at the top for the delivery of air to the'ignited gas, substantially as described.

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