  • Patent number: 4226567
    Abstract: Apparatus is provided for handling bobbins and particularly for transferring bobbins from one location to another. The apparatus includes a cart having parallel linkages pivotally mounted thereon and connected to a fluid-operated ram. A bobbin-engaging unit is carried at the ends of the linkages and engages the bobbin internally. After engagement, the linkages are manipulated to transfer the bobbin to another location with the weight of the bobbin and mechanism being offset by the fluid-operated cylinder. The cart is designed to be attached to a portable bobbin buggy so that both can then be pushed as a unit to move the buggy to a desired location from which the bobbins are transferred to a creel or rack, for example.
