Patent number: 10978860Abstract: The present invention is a portable hand tool for cutting the metal cladding of an electrical cable. The basic structure of the tool is a spring-loaded clamp comprising two opposing jaws which are biased toward closure by a torsion spring-loaded hinge mechanism. The upper jaw contains a rotating circular saw blade driven by a battery-powered electric motor, while the lower jaw contains a channel into which the cable is inserted. Application of manual pressure to the handle extensions of the two jaws has the dual effect of separating the jaws, so that the blade is raised away from contact with the cable cladding, and cutting off power to the motor, thereby stopping the blade rotation. With the blade raised and motionless, the operator can safely replace or re-position the cable in the lower jaw.Type: GrantFiled: March 4, 2020Date of Patent: April 13, 2021Inventor: Steven Wendt

Patent number: 9222057Abstract: A precision cutting tool for removing the excess wax wall of a pillar styled candle includes a ring configured to encircle the candle and a handle extending from the ring. The handle includes an extendible and retractable cutting element. The cutting element may be extended into the circle defined by the interior circumference of the ring in a gradual manner. The tool includes a recess for the cutting element to be retained when the tool is not in use. The interior of the handle includes a cutting element mover configured to cause linear movement of the cutting element into and partially out of the recess. When the mover is actuated in a direction that results in movement of the cutting element out of the recess, the cutting element extends partially into the candle located in the interior circle established by the ring. The candle or the tool may then be rotated to cause cutting into the candle wall until the excess wax wall can be removed.Type: GrantFiled: September 15, 2015Date of Patent: December 29, 2015Inventors: Richard Wheeler Munson, Brian L.

Patent number: 9088144Abstract: A tool for clamping and cutting an armor of a cable is configured with a housing extending along a longitudinal axis and configured to receive the cable, an elongated lever having a distal end pivotally coupled to a distal end of the housing; an elongated spring having a proximal end, which is riveted to the proximal end of the housing, and a distal end which terminates at a distance from the distal ends, a clamping stud coupled to the distal end of the spring. The elongated spring and the lever are configured to have a controllably slidable contact point therebetween. A torque applied to the lever translates into a spring-bending force applied to the spring and sufficient to bring the stud in contact with the armor with a clamping force depending on the location of the point of contact and smaller than the spring-bending force.Type: GrantFiled: January 12, 2011Date of Patent: July 21, 2015Inventor: Lucien Ducret

Patent number: 8112893Abstract: A cutting tool includes a frame, a shaft, a cutter and a cam. The shaft is rotatable about an axis. The cutter is coupled to the shaft such that rotation of the shaft about its axis causes rotation of the cutter about the shaft's axis. The cam is positioned around the shaft such that the cam contacts the frame upon rotation of the shaft. The cam has a cam surface which is distanced away from the axis of the shaft a varying amount such that contact of the cam with the frame upon rotation of the shaft causes the shaft, and thus the cutter, to reciprocate in a generally transverse direction relative to the axis of the shaft.Type: GrantFiled: June 2, 2008Date of Patent: February 14, 2012Assignee: Greenlee Textron Inc.Inventor: James Robert Harger

Patent number: 7891097Abstract: A cutting tool for cutting the armor includes a cutter body having first and bottom entry walls defining a channel for receiving an armored cable. There is a slot in the first wall that affords reciprocating entry into the channel of a movable cutting blade from the outside of the wall. The direction of translation into the channel defines a blade insertion direction. The slot defines a slot segment of the first wall which in turn defines a base line. A stopper is mounted on the cutter body opposite the slot on the inside of the first wall. The stopper moves toward and away from the first wall to engage an armored cable placed in the channel and releasably press the armored cable against the slot segment of the first wall. The distance in the blade insertion direction of the bottom entry wall from the base line increases as the longitudinal distance from the slot segment increases to impart a curved configuration to the channel.Type: GrantFiled: December 18, 2007Date of Patent: February 22, 2011Assignee: IDEAL Industries, Inc.Inventor: Bruce W.

Patent number: 7565740Abstract: A method of preparing the end of a coaxial cable for insertion within a coaxial cable connector involves stripping the cable jacket from the end of the cable, and reducing the outer diameter of the cable jacket portion lying adjacent the stripped portion of the jacket to a relatively constant reduced diameter. The reduced diameter portion of the cable jacket can then be reliably sealed to the back nut of the coaxial connector by an O-ring. A related preparation tool is disclosed for simultaneously stripping the cable jacket from the end of the cable, and reducing the outer diameter of the cable jacket portion lying adjacent the stripped portion, as the tool is rotated about the end of the coaxial cable. The tool may also serve to remove a portion of the outer conductor, as well as a coring member to remove dielectric surrounding the inner conductor of the cable.Type: GrantFiled: December 1, 2004Date of Patent: July 28, 2009Assignee: Corning Gilbert Inc.Inventor: Jimmy C.
