Abstract: The fishing line casting assist device comprises a body releasably mountable on the handle of a fishing rod, a rotatable line retaining member rotatably journaled in said body and having a weight coupled thereto for creating a retaining force for maintaining a fishing line trained over said line retaining member until the fishing rod is cast whereupon the casting force causes the retaining member to move to a non-line retaining position where the fishing line is free to flow out of a reel mounted on the fishing rod.

Abstract: An overhead door mechanism with torsion type counterbalance springs includes a spring adjustment device comprising a housing suitable for attachment to a horizontal shaft and a gearing mechanism that allows angular adjustment of the attached end of the spring relative to the shaft. The gearing mechanism includes a toothed ring gear member adapted for connection to the spring and rotatably mounted in the housing. A threaded worm is also mounted in the housing so that it engages the teeth of the toothed member. Rotation of the threaded worm induces a corresponding rotation of the toothed member. The rotation, when conveyed to one end of a spring that is fixed at its other end causes the spring torsion to be altered without releasing the spring from retention by the adjustment mechanism.
