Abstract:
1. A screw-less vise assembly of the type for clamping a workpiece between opposing jaws, said assembly comprising: a housing; a pair of jaws; at least one of said jaws being moveable relative to the other said jaw; an elongated clamp shaft defining a long axis; said clamp shaft slideably disposed relative to said housing; a locking element retained by said housing; said locking element having a central hole through which said clamp shaft slideably extends; a wedge supported relative to said housing; and a bridge operatively disposed between said wedge and said locking element for reciprocating linear movement in response to rotation of said clamp shaft; said bridge configured to angularly displace said locking element into canted frictional engagement with said clamp shaft and then, with continued rotation of said clamp shaft, to axially displace said clamp shaft relative to said housing thereby forcibly drawing said moveable jaw toward the other said jaw or spreading said moveable jaw away from the other said jaw.
