Abstract: Described herein is an adjustable clamp quickly and easily installed. The clamp comprises a mounting bar upon which is mounted two clamping jaws. One jaw is fixedly mounted and the other slidably mounted on the bar. The slidable jaw has a clamping pad affixed to a rod capable of reciprocating motion. From a retracted position, the rod can be advanced to bring the clamp pad in close contact with a workpiece being clamped by means of a toggle mechanism which locks the rod in its advanced position.

Abstract: A ski clamping apparatus for holding one or a pair of snow skis while sharpening and waxing the skis. A pair of identical clamps are mounted on a support, such as on a top of a desk or a cabinet, with the clamps spaced apart for supporting the ski or skis at longitudinally spaced areas. Each clamp has a pair of clamping sections, with each section adapted to hold a ski at the longitudinal edges thereof and with the bottom of the ski facing upwardly to permit filing and waxing of the bottom of the ski or adapted to hold a ski while resting on its lower edge, the upper edge of the ski facing upwardly. With such an arrangement the edges of both skis can be sharpened simultaneously by an implement mounted at a predetermined angle to the exposed upper edges.

Abstract: A work hold-down including a sleeve engaged about a column for free slidability and tiltability relative to the column, the sleeve being contractible for urgence from a tilted position toward a longitudinal position on the column, and an arm extending from the sleeve for movement therewith, the arm being downwardly engageable with a resting workpiece with the arm swung at least partially upwardly to releasably clamp the workpiece in position.
