ABSTRACT:
A workpiece supporting and clamping assembly includes a generally rigid base frame including a spaced apart parallel pair of elongated frame members having a pair of elongated top members mounted on the spaced apart frame members and extending generally transversely thereto. The top members have upper work supporting surfaces lying in a common plane and longitudinally extending opposed side portions defining clamping surfaces. Extensible and retractable clamping means are interconnected between the base frame and one of the top members for moving the latter along the frame members toward or away from the other top member to provide for clamping of the workpiece between the top members. The other top member is indexable along the elongated frame members to any one of a plurality of selected positions thereby to accommodate varying sizes of workpieces. This indexing arrangement enables said other top member to be quickly positioned relative to the first top member approximately in accordance with the relevant dimensions of a workpiece to be clamped or secured between the top members. The apparatus may be supported on a conventional work table or work bench or, alternatively, may be supported on a lightweight, collapsible support stand.
