    Abstract: A cable end preparation tool is for a coaxial cable and has a C-shaped body with an opening therein to receive the coaxial cable and a side defining a saw guide to receive a saw blade thereagainst. The C-shaped body includes a gripping rib to fit in a valley of a corrugated outer conductor when the coaxial cable is in the opening. At least one stabilizing rib is adjacent the gripping rib to receive a crest of the corrugated outer conductor thereagainst when the coaxial cable is in the opening. The C-shaped body also includes a rotation guide feature receives the inner conductor. A cutting blade extends outwardly from the C-shaped body for removing a portion of a dielectric between the inner conductor and the corrugated outer conductor as the C-shaped body is rotated about the rotation guide feature.

  • Patent number: 8024864
    Abstract: A ratcheting cutting tool for plastic pipes having first and second, elongated rigid members pivotally mounted to each other. Each rigid member has a handle and the first rigid member additionally has an anvil at an end opposite from its handle. A spring-biased, knife blade member with a cutting edge and with a plurality of ratchet teeth is pivotally mounted to the first member. The tool further includes drive and catch pawls pivotally mounted to the respective rigid members. In operation, the handles of the rigid members can be repeatedly squeezed together to progressively move the cutting edge of the knife blade member in a step-by-step manner toward the anvil to cut through a plastic pipe positioned therebetween.

  • Publication number: 20110219626
    Abstract: A drill cutting attachment for severing an electrical conductor includes a housing, a stationary cutting blade connected with the housing, a movable cutting blade pivotally connected with the stationary cutting blade for displacement about a given cutting pivot axis between open and closed positions relative to the stationary cutting blade, and a pawl and ratchet arrangement for displacing the movable cutting blade from the open position toward the closed position, thereby to sever an electrical conductor positioned between the blades. The pawl and ratchet arrangement includes a transport pawl member that is longitudinally reciprocated by a rotary drive shaft via either an eccentric and crank arm drive arrangement, or a cam and follower drive arrangement. The drive shaft has a free end with a hexagonal cross-sectional configuration for connection with the chuck of an electric drill, and an attachment sleeve connects the housing with the electric drill body.

  • Patent number: 7966681
    Abstract: A multi-function pipe cutting and fitting tool includes a spring biased connecting rod, a pair of plier teeth and a pair of friction teeth. The spring biased connecting rod improves the pipe cutting function of the tool by improving the operation of a movable jaw toward engagement of a fixed jaw. The pair of plier teeth positioned on one side of the tool allows a user to firmly grip a pipe or other object to be held in place. The pair of friction teeth positioned on an opposite side of the tool allows a user to more reliably engage an object such as a cap on a can of glue. The inclusion of all of these features in the same tool allows a user to perform multiple functions easily and more rapidly.
