GASEOUS FUEL.

No Drawing.

To all whom it may concern:

Be it known that we, (1) JAMES R. ROSE, (2) Jon HARRIs, citizens of the United States, residing at (1) Edgeworth, (2) Lakewood, in the county of (1) Allegheny, (2.) Cuyahoga, and State of (l) Pennsylvania, (2) Ohio, have invented a certain new and usefullmprovement 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 the purpose of imparting visibility to the cone within the flame produced by the burning of the hydro gen and for certain kinds of cutting and welding. As pointed out hereinbefore, it is the purpose of this invention to produce a gas which will enable the cutting operation v to be performed with greater rapidity than can be realized by the aforesaid mixtures. For this purpose we form a mixture of methane and propane with hydrogen in the proportions o from 2}% to 12?;% by volume each of such methane and propane 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 ofhydrogen alone with oxygen, and also produces in the flame a visible or luminous cone which enables the proportions of the gases to be conveniently adjusted and the flame to be applied efficiently 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 Specification of Letters Patent. Patented J n 24 1922 Application filed December 26, 1919. Serial No. 347,450.

iron and steel, and corroded, dirty and slaggy ron and steel-in which operations a large flame volume and high units are essential. However, our gaseous mixture is capable of cutting with much greater rapid- 1ty than can gases having such higher carbon content.

According to Richards on Metallurgical Calculations, published in 1908,- the flame temperature produced by the combustion of the aforesaid gases will be at least 3200 C., and the variations in the percentages of the said gases will cause the following variations in the net B. T. U. per cubic foot of mixture and 1n the cubic feet of oxygen required for the combustion of a cubic foot of such mixture:

No. 1 mixture, 95% H. with 21}% each of propane and methane; net B. T. U.s 365; cu. ft. of oxygen .650.

No. 2 mixture, 75% H. with 121}% each of propane and methane; net B. T. U.s 651: cu. ft. of oxygen 1.250. I

Having thus described our invention, what we claim is 1. A gas for cutting, welding and heating purposes consisting of a mixture of methane and propane with hydrogen in the proportions offrom 21}% to 12%70 by volume each of the'methane and propane to hydrogen.

2. A gas for cuttin welding and heating purposes consisting o a mixture of methane and propane with hydrogen in proportions- JAMES R. ROSE. JOHN HARRIS.
