Description

J. J. CROWE FLAME REGULATING cocx NGV. 3, 41931.
l y Filed Dec. 2o, 1929 Patented Nov. 3, 193i UNITED STATES PATEN'I` OFFICE i JOHN J. cnowE, or wEsTrIELD, Naw JERSEY, AssIGNon To AIR nEDUc'rroN coMPANY,
INGORPORIATED, 0F NEWr YORK, N.
Y., A CORPORATION OFV' NEW YORK FLAME REGULATING COCK Application led December 20, 1929. Serial No. 415,429.
The inventionrelates to oxyacetylene and like'torches for welding and cutting, and the object is to secure a simple and eii'ectlve means ffor .fia-me adjustment.
In the usual practice separate needle valves are placed in the oxy en and fuel gas passages of the torch, so that y independent manipulation of these valves the flame can be adjusted to a neutral composition, or to a somewhat oxidizing or somewhat carbonizing condition ifreither'should bedesired. Twohole cocks/have also been employed'for turning on and olf both gases simultaneously without disturbing needle valve adjustment.
The subject of the present invention is a torch provided with a single cock for controlling both gases, this cock being capable' of adjusting the flame in respect to neutrality by a slight turning movement of the cock in one direction or the other, and being further capable of changing the liame from a large to a small flame or vice-Versa by a. greater turning movement.
In the accompanying drawings forming a part hereof Fig. 1 is a sectional view of a double flame adjustment cock in accordancewith the invention;l f
Fig. 2 is a similar View showing the plug turned through 180.o to secure a small flame; an l Fig. 3 is a schematic plan view.
The combination constituting the invention enables the flame to be -changed from a large flame to a small flame, and vice-versa, by turning the plug 10 by its wheel 11 from one position to another .through a considerable angular distance, in this instance a halfrevolutlon, whilst also enablin the flame to be adjusted for neutrality, or or an oxidizing or carburizing composition, by slight turning movement at either of these posivolves forming the oxygen and acetylene passages 3 andl 4 in the body 9 in such manner that these passages are closer together at one side of the cock and farther apart at theopposite side, that is to'say the passages approaching the cock are offset from the passages leaving the cock. lith this arrangement, when the cock is in the position of Fig. 1 the largest areas are opened and the flame is accordingly of a larger size, whilst when the plug is in the position ot' Fig. 2 the areas of both the oxygen and the acetylene passes are out down approximately half, resultin in a smaller flame. At either of these posltions slight turning of the plug varies the areas of opening of the oxygen and acetylene passages in relation to each other, in order to adjust the percentage composition of the flame.
What I claim as new is:
In an oxyacetylene torch, a flame adjustment device consisting of a duplex plug cock having ports for oxygen and acetylene,respec tively, said ports being angularly displaced with reference to each other about the axis of the plug and also at reverse inclinations lengthwise of the plug, the approach and departure passa esin the stationary part of the cock being o set with relation to each other, so that by turning the plug from one position to another the area-s of opening are changed from large to small or vice-versa whilst by slight turning of the plug at either position the ratiov is variable.
' JOHN J, CROWE.
