In an article gripping device, the combination of a frame including a pair of opposed, spaced side plates, each side plate having a lower upwardly and outwardly inclined cam surface and an upper inwardly and upwardly inclined cam surface connecting to the upper end of said lower surface, a gripper jaw carrier member slidably positioned on said frame between said side plates for movement on a vertical axis relative to said frame, a pair of gripper jaws pivotally carried by said jaw carrier member at a lower end thereof and positioned in opposed relation between and protruding downwardly from said side plates, cam follower surfaces being formed on upper portions of said gripper jaws and engaging said cam surfaces, said cam follower surfaces comprising a pair of vertically spaced surfaces on each gripper jaw with the two cam follower surfaces of each gripper jaw normally concurrently engaging each of said two cam surfaces to control, positively, the positions of said gripper jaws as changed by the relative vertical position of said jaw carrier member on said frame, and a spring urging the jaw carrier member to gripper jaw article engaging position, said cam follower surfaces engaging said cam surfaces at all times to control the position of said gripper jaws.
