Image Number 3 for United States Patent #4588068.
A parison transferring device for use in transferring glass parisons from a parison forming mold to a blow mold. The device comprises gripping members operable to grip or release a parison. The gripping members are movable about a horizontal axis between a gripping position and a releasing position. A cylinder is mounted on a horizontal shaft and has the gripping members mounted thereon. A piston is movable in the cylinder and is screw-threadedly connected to the shaft so that movement along the cylinder causes the piston to rotate about the horizonal axis. A driving connection between the piston and cylinder causes the cylinder to rotate when the piston does so.
