Abstract

1280435 Clamps L F BLATT 12 Jan 1971 [19 Jan 1970] 1549/71 Heading E2B A clamp comprises a body consisting of a pair of identical abutting body members 14, 16 each of which has a pair of pivot holes 30 for selectively pivotally mounting a clamping arm 44 between the body members the pair of pivot holes being spaced and also aligned with the other pair of pivot noles, the body members defining a longitudinal bore 38, there being formed upon the interior of the body members a pair of substantially enclosed guide tracks communicating with the bore 38, bores 26, 28 for mounting the body members on a support structure, a clevis 54 movable reciprocally in the bore 38 and having spaced legs and hydraulic or pneumatic cylinder and piston or solenoid connected to the clevis for reciprocation thereof, an axle 52 transversely connecting the legs and provided with a guide block 58 on each outer end thereof slidable along the tracks, and the clamping arm 44 having a pivot bore 45 and a follower slot 50 offset and inclined from the axis of the bore 38 and being mounted for pivotal movement between the opposed body members, the axle 52 being confined within the slot or the pivot bore. Each body member comprises a plate 18 each plate having upstanding end ribs 20, 22 and a transverse connecting rib 24. Each plate has bores 26 and each rib 24 has bores 28 for mounting the clamp. The ribs 24 extend along the length of the plates and the end portion of each plate is offset inwardly and is inwardly grooved to provide guide tracks for the clevis 54 connected to the piston of a hydraulic cylinder 40. The clamping arm 44, either has a pivot bolt 46 in one pair of holes 30 and the clevis axle 52 engages in the inclined slot 50, or the clevis axle engages the pair of holes 30 and a cam roller 60, Fig. 6, on the pivot bolt 46 engages in the slot, in the latter case the clamping arm moves both longitudinally and rotationally. The clamping arm moves clockwise or anticlockwise according to whether the arm pivots about the lower or upper holes 30 towards a clamping surface.
