Description
Upon a displacement of plate 1 downward cross-piece 2 begins to descend. At this, flange 9', joined by pins b to flange 9 which is mounted freely on cross-piece 2, reaches stop 6 and clamps the ends of levers 3 by over coming the resistance of spring 4. The lower ends of levers 3 are brought together so that they enter and grip workpiece 5. As plate 1 moves upward, cross-piece 2, together with levers 3 and workpiece 5, begins to rise, freeing feeding disk 7. When flange 9 reaches upper stop 8, flange 9 begins to descend with respect to cross-piece 2, while plate 1 of the press continues to rise, completing its stroke. At this, cone a of the flange spreads the upper ends of levers 3, thereby bringing their lower ends together to release the workpiece. Then plate 1 descends again with cross-piece 2, levers 3 grip the next workpiece and the cycle is repeated. $808$LW,SF$
