  • Patent number: 4151672
    Abstract: An elongated hollow tapered shaft, preferably of fiberglass construction, receives an elongated wire insert fabricated from steel wire for example. The insert includes a head formed at its base end to engage and bind with the interior wall of the base end of the shaft, to limit movement of the insert into the shaft; and this head provides a hook for attaching one end of an elastic line. The insert is somewhat shorter than the shaft and has an attachment loop formed adjacent to the tip end. A fishing line is attached to the attachment loop, extends toward the base end and passes through a ring attached to the free end of the elastic line, with the fishing line then extending toward and beyond the tip end of the shaft. The elastic line withdraws a storage loop of fishing line between the attachment loop and the attachment hook of the insert, which storage loop allows for a variable length of fishing line extending beyond the tip of the fishing rod.

  • Patent number: 4121369
    Abstract: A fishing rod assembly includes an elongated hollow fiberglass rod having an end plug secured to its butt or handle end, the end plug having an eyelet extending into the rod to which fishing line is attached. The fishing line includes a length of elastic line attached to the end plug and retained within the rod bore, and a length of nonelastic line coupled to the elastic line by means of a coupler and extending from the tip end of the hollow rod. The coupler coacts with a limit structure within the rod adjacent the tip end to prevent the elastic line from passing out of the tip end; and the limit structure may be a transverse pin or other internal protuberance such as a sleeve. A stop attached to the nonelastic fishing line coacts with the tip into the rod to limit withdrawal of the line into the rod and fix the limit of maximum contraction of the elastic line. An external finger projects from the rod tip end to coact with a locking loop in the line and fix the length of line which extends from the tip end.
