  • Patent number: 5201495
    Abstract: A fish tape reel which includes first and second hollow annular reel segments mated together to define a fish tape reel having an enclosed annular fish tape compartment for receiving a lenth of coiled fish tape. The reel defines first and second spaced-apart and opposing side walls and inner and outer spaced-apart and opposing peripheral walls. The inner peripheral wall defines a through void in the reel. A port is provided in the inner peripheral wall of the reel for extending and retracting therethrough a length of fish tape contained in the compartment.

  • Patent number: 4766919
    Abstract: An umbrella and a temporary shelter comprised of a plurality of the connected together umbrellas includes a protective sheet having at least three straight sides. An elongate pole is attached to the center of the protective sheet for spacing the sheet in a predetermined spaced-apart relation above a surface. Ribs are attached to the sheet and means are provided for opening and closing the umbrella. Connecting means cooperate with the protective sheet for connecting together a plurality of like umbrellas along adjacent sheet edges to form a relatively large temporary protective shelter.

  • Patent number: 4329078
    Abstract: The invention relates to a lock for a splice joint used to releasably join two poles together end to end. The lock prevents the inadvertent withdrawal of the leaf spring finger from the superimposed holes of the splice joint. The lock comprises a ring rotatably positioned on one of the poles astride the leaf spring and having an inner surface comprised of a first, relatively large diameter segment which, when rotated into radial alignment with the leaf spring, permits withdrawal and a second, relatively smaller diameter segment which, when rotated into radial alignment with the leaf spring, frictionally engages and clamps the leaf spring to the pole and prevents withdrawal of the leaf spring finger.
