  • Patent number: 4358143
    Abstract: The disclosure is directed to apparatus (11) for lifting, maneuvering and transferring a roll of material to an independently supported shaft (93). The apparatus is adapted for suspension from an overhead crane and comprises an elongated frame (12) the lower end of which is pivotally connected to a torque assembly (14) that includes a center probe (15). The center probe includes a plurality of radially expanding teeth (49) that engage the inner surface of the roll core and retain it on the center probe (15). An actuator (13) of the extensible-retractable type is pivotally connected between the upper end of the elongated frame (12) and one end of the torque arm assembly (14). Extension and retraction of the actuator (13) causes the torque arm assembly (14) and center probe (15) to move between substantially vertical and horizontal positions. The extreme end of the center probe includes a coupler (61) that releasably interlocks with a coupler (94) secured to the end of the machine shaft (93).
