Abstract:
1. A clamp for clamping sheets and like material, said clamp comprising: opposed elongate clamping jaws mounted for pivotal movement between a clamping condition and a relatively open, released, condition; two latch devices for effecting movement of the jaws spaced along the length of the jaws, said latch devices comprising a latch lever pivotable between a stable latched position and a released position, said latch lever being linked to the jaws such that relatively small pivot movement of the latch lever is amplified into larger movement of the jaws, said latch devices being adjustable to accommodate variation in the thickness of material to be clamped and to permit variation of clamping pressure; and a member of channel section common to both latch devices and carrying each latch device extending along substantially the entire length of the clamp, an upper part of the jaws being mounted within the member of channel section whereby opposite sides of the member cooperate with the jaws to control movement of the jaws upon operation of the latch devices and wherein the member of channel section also provides a slidable mounting for components associated with the clamp to enable ready adjustment of the mounting positions of such components along the clamp.
