Abstract: 881,496. Gripping devices for handling articles. ATLAS-WERKE A.G. Feb. 17, 1958, No. 5150/58. Class 78 (4). A gripper unit, comprising gripper arms which are mounted so as to be movable towards each other into gripping engagement with the articles, is provided with locking means to hold the arms open after release of the articles, said locking means being released automatically when the arms are positioned to grip further articles. As shown, gripper arms 1-4 are pivotally mounted on a frame 25, the arms 2, 4 being connected by pivoted links 21, 22 to sleeves 17 which are slidable on rods 23, secured to the frame 25, and which are secured to a frame 10. Before lowering the gripper unit to engage articles 44, the arms are locked in their open position by means of levers 37 which are pivoted to the sleeves 17 and which are provided with pawls 36, the pawls engaging in slots 39, 40 in the sleeves 17 and rods 23 respectively, thereby preventing relative movement between the frames 10, 25. As the unit is lowered by lowering a tube 34, secured to the frame 10 and slidable in a sleeve 35 in an upper structure 33, the levers 37 engage weighted pivoted levers 42 which, when the gripper arms contact the article support 8 thereby removing the weight of the frame 25 from the pawls 36, raise the levers 37 to withdraw the pawls from the slots. During initial raising of the frame 10, the frame 25 remains stationary, wedges 6 mounted on a U-shaped frame secured to the frame 10 move up between the arms 1, 3 to force them apart, and sleeves 17 move up on the rods 23 to pivot the arms 2, 4 into engagement with the articles. Downward movement of the gripper arms may be interrupted at any predetermined level by means of a braking device 117 to which racks 28, 29 connected to the rods 23, are connected by means of a free-wheeling device 118 and gear-wheels 119, as described in Specification 881,497. Operation of a motor to raise and lower the gripper unit may be controlled by switch gear actuated by tappet rods and vertically displaceable feelers, Fig. 3 (not shown).
