When piston 1 is moved to the left by the action of fluid delivered to the right end of the cylinder, motion is transmitted through roller 2, mounted in the piston rod, and link 3, connected by turning pair A to lever 4. Lever 4 turns about fixed axis B and exerts pressure with its profiled lug b on plunger 5, moving it to the left in guide a so that it clamps several workpieces 6. Each workpiece is also pressed downward by a bevelled swivelling member 7. The workpieces are released in the return stroke of piston 1 when fluid is delivered to the left end of the cylinder.
