  • Patent number: 4202509
    Abstract: A portable cart for carrying boxes of coiled insulated wire and a method of pulling the coiled wire from the portable cart are disclosed. The cart includes a frame assembly having a plurality of interconnected horizontal and vertical frame members which define compartments spaced in a line along the major axis of the vehicle. Adjacent compartments are in fluid communication with each other by passages formed through common horizontal frame members. A guide assembly is mounted on the uppermost horizontal frame member which has a passage formed therethrough substantially aligned with the other passages and the holes defined by the loops of the coiled wire when the boxes of the coiled wire are disposed in their respective compartments. A collar member of the guide assembly guides the unwound portions of the wires and allows the unwound portions to be pulled therethrough individually, or simultaneously with selected ones of the unwound wire without disturbing the remaining unselected unwound wires.
