Patent number: 8024864Abstract: 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.Type: GrantFiled: December 5, 2008Date of Patent: September 27, 2011Inventor: Mark A. Mortensen

Publication number: 20110219626Abstract: 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.Type: ApplicationFiled: August 25, 2009Publication date: September 15, 2011Applicant: WEIDMUELLER INTERFACE GMBH & CO.

Publication number: 20110185577Abstract: An improved hand-held cutting tool includes a first double-sided handle member having a front open cavity for receiving an anvil member. A second double-sided handle member having an upper open cavity for receiving a biased auxiliary handle therein and a front open cavity for receiving a blade holder therein. The first and second handle members are pivoted between a first open work piece placement position and a second open blade replacement position. The first open position allows a work piece to be placed on the anvil member to be cut and the second open position allows access to the blade holder for blade replacement without using tools. The auxiliary handle is biased out of the upper open cavity in the first open position to allow a user to grasp the auxiliary handle and the first handle member with one hand to easily achieve an initial cutting operation.Type: ApplicationFiled: February 4, 2010Publication date: August 4, 2011Inventor: John S. Ronan

Patent number: 7966681Abstract: 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.Type: GrantFiled: April 21, 2009Date of Patent: June 28, 2011Inventor: Robert Harris
