Including Rotary Cutter Patents (Class 30/90.3)
  • Patent number: 11433465
    Abstract: Ring cutting jigs are disclosed that include a base; and a sliding brace. The base may include a platform and a pair of arms. A saw guide slot may be positioned within the base. Channels may be included within the base such that the sliding brace may move parallel to the channels with the assistance of pins that ride in those channels. The cooperation of the base and the sliding brace may act to secure a coil between the base and the sliding brace such that the coil may be cut into jump rings.

  • Patent number: 10978860
    Abstract: 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.

  • Patent number: 9222057
    Abstract: 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.

  • Patent number: 9088144
    Abstract: 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.

  • Patent number: 8676018
    Abstract: An optical fiber stripper that may cooperate with an optical fiber handler for stripping one or more coating from an optical fiber is disclosed. The stripper is used as a part of a termination system for preparing the optical fiber for an optical connection, thereby providing the craft with a simple, reliable, and easy termination of the optical fiber. By way of example, the stripper cooperates with an optical fiber handler having an optical fiber secured therein for preparing the end of the optical fiber for a mechanical splice in a fiber optic connector.

  • Patent number: 8296956
    Abstract: The present invention relates to pliers for removing an insulating layer of an electrical cable, in particular a coaxial cable. The inventive pliers comprise a cutting element. The distance of the cutting element from a seat for the cable is adjustable. Furthermore, the cutting element has a degree of freedom in a circumferential direction of the coaxial cable relative to the seat.

  • Patent number: 8181350
    Abstract: A precision cutting system for efficiently cutting through an external member (i.e. conduit, etc.) without damaging internal components (i.e. wires, cables, etc.). The precision cutting system generally includes a first support structure including a first inner end and a first outer end, a second support structure including a second inner end, a second outer end and an opening extending between thereof, wherein the second support structure attaches to the first support structure and a guide structure extending from the second support structure opposite the first support structure. The first support structure attaches to a cutting tool, wherein the blade of the cutting tool extends between the first inner end and the first outer end of the first support structure, through the opening of the second support structure and adjacent the guide structure.

  • Patent number: 8112893
    Abstract: 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.

  • Patent number: 7891097
    Abstract: 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.

  • Patent number: 7565740
    Abstract: 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.

  • Patent number: 6779273
    Abstract: A cutting tool that can be used to form a stepped cable end prior to the attachment of an electrical connector to a coaxial cable. The cutting tool has a blade assembly supported inside a housing on a pair of cams. A coaxial cable is inserted into the cutting tool and the housing is rotated about the cable to push the blade assembly along spiral tracks in the cams. According to one embodiment of the invention, the blade assembly has three blades, each blade sized and positioned to make a cut of the corresponding appropriate depth in the coaxial cable thereby forming the desired stepped cable end. Cutting tools of the invention may be adapted for preparation of large-diameter (e.g., over 1 inch) coaxial cables.
