Multiple clamp and indexable anvil therefor

Claim 2

A clamping device comprising: an L-shaped base including a pair of arms each having a generally flat upper surface for engaging a workpiece, said arms being disposed at a right angle to one another in a generally horizontal plane; a fixed jaw upstanding from said base at the intersection of said arms, said jaw having a generally flat vertical clamping surface facing in the direction of each of said arms; a screw supporting post upstanding from the distal end of each of said arms, each of said posts having a threaded aperture therethrough parallel to said arm and directed toward said fixed jaw; a threaded screw received in each of said apertures and arranged to cooperate therewith for holding a workpiece against said fixed jaw; and a supporting tab extending from each of said arms generally adjacent said screw supporting post and in a direction parallel to the other of said arms, each of said screw supporting posts having a side surface that is coplanar with the clamping surface of said fixed jaw facing in the direction of the other of said arms, and each of said supporting tabs having an upper surface that is coplanar with the upper surface of the other of said arms, whereby said screw supporting post and said tab of one arm provide support and alignment for the workpiece held in the other of said arms.

Claim 3

A clamping device as set forth in claim 1, wherein said L-shaped base includes a generally flat-lower surface and generally flat outer side surfaces for resting said clamping device in a horizontal or a vertical orientation on a generally flat work surface.

Claim 4

A clamping device as set forth in claim 2, wherein said fixed jaw defines a solid square post.

Claim 5

A clamping device for simultaneously holding a plurality of work pieces, said device comprising: a first clamping means including an upstanding fixed jaw, a base arm extending longitudinally from the bottom of said fixed jaw, and means on said arm for moving a movable jaw toward and away from said fixed jaw to hold and release a workpiece disposed between said jaws; a second clamping means including a second upstanding fixed jaw adjacent said first fixed jaw, a second base arm extending longitudinally from said second fixed jaw and forming a right angle with said first base arm, and second means on said second arm for moving a second movable jaw toward and away from said second fixed jaw to hold and release a second workpiece disposed between said jaws; said first and second fixed jaws being formed integrally with one another and comprising a solid square post upstanding from said arms at the intersection thereof; and an indexable anvil comprising a plurality of interally facing external clamping faces having generally non-planar surfaces for cooperating with said movable jaws to hold irregularly shaped workpieces and a square shaped vertical passage through said anvil sized to be slidably disposed over said integral fixed jaws, whereby said anvil can be selectively disposed over said fixed jaws in a plurality of positions for holding said workpieces.

Claim 6

A clamping device for simultaneously holding a plurality of work pieces, said device comprising: a first clamping means including an upstanding fixed jaw, a base arm extending longitudinally from the bottom of said fixed jaw, and means on said arm for moving a movable jaw toward and away from said fixed jaw to hold and release a workpiece disposed between said jaws; a second clamping means including a second upstanding fixed jaw adjacent said first fixed jaw, a second base arm extending longitudinally from said second fixed jaw and forming a right angle with said first base arm, and second means on said second arm for moving a second movable jaw toward and away from said second fixed jaw to hold and release a second workpiece disposed between said jaws; said first and second fixed jaws being formed integrally with one another and comprising a solid square post upstanding from said arms at the intersection thereof; and an indexable anvil comprising a plurality of interally facing external clamping faces having generally non-planar surfaces for cooperating with said movable jaws to hold irregularly shaped workpieces and a square shaped vertical passage through said anvil sized to be slidably disposed over said integral fixed jaws, whereby said anvil can be selectively disposed over said fixed jaws in a plurality of positions for holding said workpieces.

Claim 7

A clamping device as set forth in claim 4 wherein at least one of said external faces of said anvil includes an elongated V-shaped recess for cooperating with a workpiece having a generally cylindrical external shape.

Claim 8

A clamping device as set forth in claim 4 wherein at least one of said external faces of said anvil is generally convex for engaging at workpiece having a generally concave external surface.

Claim 9

A clamping device as set forth in claim 4 wherein at least one of said external faces of said anvil includes a generally conical recess for engaging a workpiece having a generally convex external surface.
