  • Patent number: 4856688
    Abstract: The disclosed device consists of a unitary structural piece formed as two loops, meeting edge-to-edge like a figure eight, except the loops are rotated to be normal to one another; and aligned diametrically. The loops may be circular in shape, and may be between approximately one and four inches in internal diameter. One embodiment has the loops molded of a high strength plastic, such as polyethylene; while another has the loops cast of a lightweight metal, such as an aluminum alloy, coated then with a non-marring overwrap, such as a plastic or rubber. The loops are formed of circular cross-sections, between possibly 0.2-0.5 of an inch in diameter. Hangers can be hooked onto either loop; and the other loop can be fitted over a structural hook, such as in an automobile, or can be fitted over someone's finger(s), in carrying the device.

  • Patent number: 4797111
    Abstract: The disclosed battery terminal bolt is of a unitary assembly, having an elongated threaded stem terminating at an englarged body or head, and a plurality of arms rigidly projected radially from the body or head at a location axially spaced from the threaded stem. The arms may be angled slightly out of perpendicular relative to the threaded stem, in a direction axially away from the threaded stem; or may be perpendicular relative to the threaded stem. The arms provide convenient places to allow for the temporary and separable connection of alligator clamps of a jump cable. The bolt may be formed of separate components secured together, including one component having the head and threaded stem, and one component having the arms. The unitary bolt assembly may be copper plated for improved conductivity.
