ABSTRACT:
A rotary vise structure comprises a worktable journally mounted for rotation in a base member which includes a releasable latching rod adapted to engage selected openings in the worktable to hold the worktable in selected angular positions. The latching rod may be released to allow the worktable to be indexed to alternative angular positions, and the latching rod may also be held by a retainer in the released position to allow free rotation of the worktable. The worktable includes adjustable jaws for clamping articles thereon, the jaws being received in slideways of inverted-T profile. The worktable is made up of a plurality of plates secured face to face, the plates being appropriately slotted to define the inverted-T shaped slideways.
