ABSTRACT:
A combination work table and vise. The work table is vertically adjustable and has a tiltable work platform which is tiltable about a longitudinal axis so as to provide a sloped working surface. The tiltable work platform also reduces the dimensions of the work table for transportation and storage. The work platform includes at least two leaves, at least one of which can be moved laterally relative to the other to provide a vise action between the leaves. Lateral leaf movement is accomplished by means of a hand crank and screw combination. The hand crank is rotatably mounted to a first leaf while the screw is threadedly engaged in a swivel block mounted to a second leaf. Rotation of the hand crank moves at least one leaf relative to the other and thereby accommodates clamping a workpiece between the two leaves in an action similar to the jaws of a vise. The swivel accommodates asymetrical, lateral movement of the second leaf thereby accommodating clamping of a nonsymetrical object between the two leaves. The hand crank may also be interconnected to a second swivel to provide both leaves with asymetrical lateral movement.
