Abstract
Abstract The disclosure is to a device which can be employed in combination with a welding torch fixed therein in a predetermined position and direction, the device being adapted to be moved, carrying the torth therewith, in straight line direction, or to be swung in cutting with a predetermined radius. The device, as used in straight line parting or beveling, may be fixed to a structural member that is to be beveled or parted, or otherwise cut in any predetermined manner. To cut a circle or arc, the device is adapted to be magnetically or otherwise mounted on the plate or shape thus to be cut.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
188 words
A parting and beveling device comprising a holder mount for a holder assembly including a gooseneck supported by said mount for rotation about a vertical axis and having a yoke disposed above said mount and horizontally outermost, a linkage bar with inner end pivotally mounted on a transverse axis through said gooseneck yoke, a succession of yoke members pivotally connected by yokes innermost and providing transverse pivot axes including a transverse pivot axis provided by the innermost of said yoke members on which the outer end of said linkage bar is pivotally mounted, the outermost of said yoke members providing a pivot rod, and a clamp ring swingably mounted to rotate about said pivot rod to hold the nozzle of a burning torch directed angularly in three dimensions when said preceding holder assembly members are clamped rigidly by holder assembly included clamp means, holder mount support means including a plurality of parallel extending slide ways, with ways slidably mounting said holder mount thereon, said holder mount support means including means to affix to work structures or in fixed adjacency with work structures to be burned by said torch.
Claim 2
Dependent Claim
188 words
A parting and beveling device comprising a holder mount for a holder assembly including a gooseneck supported by said mount for rotation about a vertical axis and having a yoke disposed above said mount and horizontally outermost, a linkage bar with inner end pivotally mounted on a transverse axis through said gooseneck yoke, a succession of yoke members pivotally connected by yokes innermost and providing transverse pivot axes including a transverse pivot axis provided by the innermost of said yoke members on which the outer end of said linkage bar is pivotally mounted, the outermost of said yoke members providing a pivot rod, and a clamp ring swingably mounted to rotate about said pivot rod to hold the nozzle of a burning torch directed angularly in three dimensions when said preceding holder assembly members are clamped rigidly by holder assembly included clamp means, holder mount support means including a plurality of parallel extending slide ways, with ways slidably mounting said holder mount thereon, said holder mount support means including means to affix to work structures or in fixed adjacency with work structures to be burned by said torch.
Claim 3
Dependent Claim
37 words
A parting and beveling device as claimed in claim 1, in which said holder mount is adapted to release said gooseneck to be swung about a vertical axis in operation whereby to cut oUt a round plate.
Claim 4
Dependent Claim
39 words
A parting and beveling device as claimed in claim 2, in which said holder mount support means includes magnetized means to hold said holder support means rigid with relation to work while it is being burned by said torch.
Claim 5
Dependent Claim
20 words
A parting and beveling device as claimed in claim 1, in which said linkage bar is selectively of various lengths.
Claim 6
Dependent Claim
76 words
A parting and beveling device as claimed in claim 1, in which said holder mount support means includes three parallel ways header mounted at each end, with said holder mount slidably mounted on two of said ways to carry said holder assembly including torch held thereby in straight line burning, and clamp means slidable on said third way into position to be fixed to, or in rigid adjacency with the work to be burned, as aforesaid.
Claim 7
Dependent Claim
69 words
A parting and beveling device as claimed in claim 1, in which said holder mount support means includes three parallel ways header mounted at each end, two ways carrying said holder mount slidably therealong, and a third way carrying clamps immobilized for work clamping but carrying magnetized means on the bottoms of said clamps to affix said holder mount support means with relation to the work to be burned.
Claim 8
Dependent Claim
32 words
A parting and beveling device as claimed in claim 1, in which said gooseneck carries a wheel on the bottom thereof and mounted on anti-friction means for rotation within said holder mount.
Claim 9
Dependent Claim
35 words
A parting and beveling device as claimed in claim 7, in which a bottom closure plate flush with the bottom of said holder mount retains said anti-friction means to bear in operation against said wheel.
Claim 10
Dependent Claim
51 words
A parting and beveling device as claimed in claim 2, in which said holder mount includes a collar centrally on top thereof through which said gooseneck extends vertically upwardly, and set screw means passed sidewardly through said collar and withdrawable from gooseneck contact as said means adapted to release said gooseneck.
Claim 11
Dependent Claim
36 words
A parting and beveling machine as claimed in claim 1, in which said holder assembly included clamp means inlcudes a set screw passed through said clamp ring to clamp said pivot rod to said clamp ring.
