Abstract: A fishing rod wrapping device consisting of a fixed frame adapted to support one or more spools of wrapping thread for axial rotation, a friction device resisting rotation of said spool whereby thread may be paid out therefrom under a controlled and adjustable tension, a support for a fishing rod adapted to support the rod in parallel relation to the spool, so that the thread, when attached to the rod, is wrapped on the rod when the rod is manually rotated about its axis, the rod support being configurated to maintain the rod parallel to the spool, to retain the rod thereon despite any degree of thread tension, and to permit locking of the rod against movement relative to the spool whenever interruption of the wrapping process may be desired, whereby to preserve both the rod position and the thread tension until the process is recommenced.

Abstract: A line winding device for fishing reels consisting of a holder for a spool of bulk line mountable on any rigid support, line being extendable from the spool for winding on the reel of a fishing rod, the holder being adjustable to position the spool in various positions relative to the support and to the fishing rod to provide twist-free and kink-free winding of the line on the reel, regardless of the type of reel being used.

Abstract: A fish filletting knife consisting of a blade having a pair of extension members each pivoted at one end to the base of the blade, the extension members being movable between one position in which they form a carrying case enclosing the blade in order that it may be carried safely in the pocket or tackle box, and a second position in which they form a handle from which the blade extends in a use position, and a locking device operable to secure the blade rigidly relative to the extension members in either of said positions.

Abstract: A device for determining the string tension in the netting of a racket has a base and clamping structure adapted to be intercoupled on opposite faces of the netting, and a compressible, spring-loaded plunger slidably mounted on the base for shifting movement against one face of the netting. Movement of the plunger against the face of the netting deflects the latter and also compresses the plunger such that an equilibrium position is reached wherein the compression force on the plunger spring is equal to the resistance force presented by tension in the strings of the racket netting. A tension gauge is provided for measuring the deflection of the netting at the equilibrium point and translating the deflection measurement into a tension reading corresponding substantially to the actual tension in the racket strings.
