  • Patent number: 4741356
    Abstract: A variable riser conduit for the adjustable vertical positioning of a fire hydrant both in conjunction with, and subsequent to, completing the hydrant installation. The riser conduit is formed of a housing which may be tubular, having a passageway therethrough and also having annular collars disposed around and adjacent each end margin of the passage. These collars cooperate with mating flanges on the shoe of the hydrant at one end and the water main or auxiliary valve at the other end to provide a water tight mechanically restrained joint when a split restraint collar is secured and tightened in place behind each annular collar. The ends of the passage are parallel and laterally offset or disposed one to another such that, when the restraint collar is loose or loosened, the riser conduit may be rotated with respect to both hydrant and water main.

  • Patent number: 4721174
    Abstract: A light-duty fish weight scale which is connectable to generally horizontal elongated supports such as fishing rods and the safety rail of a boat. The fish scale includes a shank formed of slender, flexible resilient material such as wire or a strip of flat sheet material and is connectable at one end to the elongated support whereby the shank is then spaced generally parallel to the support. The shank is adapted to supportively receive the downwardly hanging weight of a fish and be deflected in cantilever fashion in proportion to the weight of the fish. The other end of the shank is adapted, in conjunction with weight indicia connectable to the support, to provide viewable indicia of the actual weight of the hanging fish. In one embodiment, the means for hanging the fish from the shank also provides a pointer to the proper weight indicia, facilitates the stored position for the invention, and provides means for securing the fish hook attached at the end of the fishing line when the fishing rod is not in use.
