Abstract
A burner for use in a flame scarfing apparatus including a plurality of flame scarfing sections, a transverse bore extending through the burner, a screw-threaded bolt disposed within the bore, chamber sleeves disposed about the bolt and spaced to correspond to approximately the length of the flame scarfing sections and O-rings mounted in annular grooves formed intermediate the sleeves so that tightening nuts on the bolt compresses the O-rings into sealing engagement against the surface forming the transverse bore.
Claims8
A gas supply device comprising a housing having a first bore therethrough and a plurality of spaced inlet and exit bores intersecting said first bore, an elongated member axially slidably disposed in said first bore, said elongated member further comprising at least two sleeves and an elongated rod member disposed axially through a portion of at least two sleeves, a plurality of compressible seal members disposed around said rod member and between said sleeves, said seal members loosely engaging the surface forming said first bore and being positioned to separate at least one of said inlet bores from other inlet bores and to separate at least one of said exit bores from other exit bores, and means accessible from the exterior of said housing for threadably engaging said rod member whereby rotation of said meand draws said sleeves axially toward each other to thereby selectively compress said seal members radially outwardly into fluid-tight engagement with the surface defining said first bore.
A gas supply device comprising a housing having a first bore therethrough and a plurality of spaced inlet and exit bores intersecting said first bore, an elongated member disposed in said first bore and having a plurality of compressible seal members disposed thereon loosely engaging the surface forming said first bore, said seal members being positioned to separate at least one of said inlet bores from other inlet bores and to separate at least one of said exit bores from other exit bores, and means accessible from the exterior of said housing to selectively compress said seal members into fluid-tight engagement with the surface defining said first bore wherein said last mentioned means comprises a plurality of sleeves disposed on said elongated member between said seal members and means disposed exteriorly of said housing for drawing said sleeves together on said elongated member to thereby compress said seal members and wherein said elongated member is provided with external threads on both ends thereof and said means for drawing said sleeves together comprises nut members each movable along said threads respectively into engagement with one of said sleeves.
