Abstract

Abstract A machine mounted cutting torch is disclosed comprising a support means having a horizontal end portion positioned above the material being cut. A cutting tip support turret is selectively rotatably mounted on the end portion of the support means and has a plurality of spaced apart cutting tips secured thereto extending radially outwardly therefrom. A spring detent means is provided to yieldably maintain the turret in various positions with respect to the material being cut so that the selected cutting tip will be yieldably maintained in an operative position. A conduit means extends through the support means and the turret so that oxygen and industrial gas are supplied only to the cutting tip which is in the operative position. Means are provided to prevent the escape of gas from the turret. Control means is provided for supplying the desired oxygen and gas volumes and ratios to the cutting tip.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 98 words
A machine mounted cutting torch comprising, a first support means positioned above the material being cut, a second support means comprising a tip support turret having spaced apart heads, said turret being rotatable about a horizontal axis with respect to said first support means, said turret heads having bores extending therethrough, said heads having a tip mixer assembly having a plurality of bores extending therethrough, said mixer assembly being threadably secured to said heads, the bore of said tip mixer assembly being maintained in sealed relationship with respect to the bore of said heads to prevent gas leakage.
Claim 2
Dependent Claim 98 words
A machine mounted cutting torch comprising, a first support means positioned above the material being cut, a second support means comprising a tip support turret having spaced apart heads, said turret being rotatable about a horizontal axis with respect to said first support means, said turret heads having bores extending therethrough, said heads having a tip mixer assembly having a plurality of bores extending therethrough, said mixer assembly being threadably secured to said heads, the bore of said tip mixer assembly being maintained in sealed relationship with respect to the bore of said heads to prevent gas leakage.
Claim 3
Dependent Claim 29 words
The torch of claim 1 wherein means is provided for yieldably selectively maintaining said turret in various of its positions of rotation with respect to said first support means.
Claim 4
Dependent Claim 13 words
The torch of claim 2 wherein said means comprises a spring detent means.
Claim 5
Dependent Claim 52 words
The torch of claim 1 wherein first and second conduits extend through said first support means, said turret having a plurality of radially extending pairs of conduits which are selectively rotatable into communication with said first and second conduits, each of said cutting tips being in communication with one pair of conduits.
Claim 6
Dependent Claim 101 words
The torch of claim 1 wherein said one end has a tapered head portion thereon, said second support means comprising a central portion having a tapered cavity formed therein which rotatably receives said tapered head portion, means for maintaining said central portion on said head portion in a sealed relationship, said cutting tips being secured to said central portion and extending radially outwardly therefrom, said first support means having a conduit means extending therethrough, said central portion having a plurality of conduits formed therein in communication with said cavity, said tips being in communication with said conduits in said central portion.
