摘要： 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.

摘要： 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.
摘要翻译： 具有扭力型平衡弹簧的顶部门机构包括弹簧调节装置，该弹簧调节装置包括适于附接到水平轴的壳体和允许相对于轴的弹簧附接端部进行角度调节的传动机构。 齿轮机构包括适于连接到弹簧并可旋转地安装在壳体中的齿圈齿轮部件。 螺纹蜗杆也安装在壳体中，使其与齿形构件的齿啮合。 螺纹蜗杆的旋转引起齿形构件的相应旋转。 当传送到固定在其另一端的弹簧的一端时的旋转导致弹簧扭转改变，而不会使弹簧不被调节机构保持。
