Abstract: A tool for cutting and removing a nut from a threaded shank member extending beyond the nut, a particular application being to remove from the depending end portion of the shank of a faucet the nut securing the faucet to a sink. A body is formed with a pair of substantially parallel bores, one of which is threaded along its entire length for attachment to the shank. One portion of the other bore is threaded to receive a bolt, the remaining portion of the other bore is smooth walled to receive a plunger which has a chisel edge at its end nearest the nut. The bolt engages the chisel edge to drive it between an inoperative position and an operative position engaged with the nut at which point continued advancement of the bolt results in breaking and removal of the nut.

Abstract: A notching tool for forming notches in ridge- or hip-capping for roofs, the notches being formed to match the profile of the roofing sheets.The tool has a base with a pair of spaced feet which engage the ribs on the roofing sheets to align the tool. A notching head on the base has a replaceable die and punch pair, one of which is fixed to support the capping while the other is manually or power-operated to provide a shearing-type cutting action between the die and punch to cut the notches. Adjustable guides on the notching head support the capping for angular alignment between the capping and the notching head and for adjustment of the depth of the notch. The notching head may be pivotally and/or rotatably mounted on the base and the die and punch may be reversible.

Abstract: The invention relates to a telescopable retractable landing net for fish. The net is attached to the retractable hoop by resilient hooks. The hooks are spaced around the inner periphery of the hoop and do not extend above the upper surface of the hoop nor below the bottom surface of the hoop, the outer periphery of the hoop is substantially smooth, therefore, the hoop is free of rough surfaces that would restrict the ability of the hoop to be retracted into its hollow handle.

Abstract: A self-setting fish hook assembly includes an arm biasing spring to spread to hooks placed on first and second extending arms. A latch spring is mounted on one of the extending arms to hold the two extending arms together until a fish bites on both of the hooks and causes the extending arms to move momentarily closer together. This frees the latch spring to spring clear of the second extending arm and allows the arm biasing spring to unload, thereby spreading the two hooked arms. An embodiment which uses a coil arm biasing spring separate from the first and second extending arms allows the extending arms to be moved close together without loading the arm biasing spring.
