JAMES R. ROSE, OF EDGEWORTH, PENNSYLVANIA, AND JOHN HARRIS, OF LAKEWOOD,
OHIO, ASSIG-NOIRS TO OARBO-OXYGEN COMPANY, OF PITTSBURGH, PENNSYLVANIA,
A CORPORATION OF DELAWARE.
GASEOUS FUEL.
N 0 Drawing.
T 0 all whom 2'25 may concern:
Be it known that we, 1) JAMES R. ROSE. (2) JOHN HARRIS, citizens of the United States, residing at (1) Edgeworth, (2) Lakewood, in the county of (l) Allegheny (2) Cuyahoga, and State of (1) Pennsylvania, (2) Ohio, have invented a certain new and useful Improvement in Gaseous Fuel, of which the following is a full, clear. and exact description.
This invention relates to gaseous fuel, and more particularly to a fuel which is particularly useful for the purpose of cutting metals with great-rapidity, where extreme cleanness of cutting is not essential. A use for which our gas is particularly well suited is for cutting scrap iron.
It has been proposed heretofore to mix with hydrogen, gases such as illuminating gas and carbon monoxide, for thepurpose of imparting visibility to the cone within the flame produced by the burning of the hydrogen and for certain kinds of cutting and welding. "As pointed out hereinbefore,
1t is the purpose of this invention to produce a gas which will enable the cutting operation to be performed with greater rapidity than can be realized by the aforesaid mixtures. For this purpose we-form a mixture of ethylene with hydrogen in the proportions 'of from 5% to 25% by volume of such ethylene to the hydrogen constituents. This gas has a relatively high carbon content, which materially. increases the flame volume and heat: units over those obtainable by the combustion in a blow-pipe of hydrogen alone with oxygen, and also produces'in the flame a visible or luminous one which enables the proportions of the Specification of Letters Patent.

Application filed December 26, 1919. Serial No. 347,458.
gasesto be conveniently adjusted and the flame to be applied eflicientlv to'the work.
The carbon content of our gaseous mixture is lower than that required for operating on heavy masses of metal and for cutting cast iron and steel, and corroded, dirty and slaggy iron and. steel-in which opera-- tions a large flame volume and high units are essential. However, our gaseous mix ture is capable of cuttingwith much greater rapidity than can gases having such higher carbon content. 4
According to Richards on Metallurgical Calculations, published in 1908, the flame temperature produced by the combustion of the aforesaid mixture will be as high as 3400 (I, using the maximum percentage of ethylene, and the variations in the percentages of the said gas will cause the following variations in the net B. T. U. per cubic foot of mixture and in the cubic feet of oxygen required for the combustion of a cubic foot of such mixture:
No. 1 mixture, 95% hydrogen with 5% ethylene; net B. T. U.s 360; cu. ft. of oxygen .625.
No. 2 mixture, 75% hydrogen with 25% ethylene; net B. T. U.s 627; cu. ft. of oxygen 1.125.
Having thus described our invention, what we claim is: v
A gas for the purpose specified consisting of a mixture of hydrogen with from 5% to 25% by volume of ethylene.
In testimony whereof, we hereunto aflix our signatures.
JAMES R; ROSE. JOHN-HARRIS.
