  • Universal utility knife
    Patent number: 5012581
    Abstract: A utility knife especially suitable for use by either right-handed or left-handed persons includes a generally symmetrical casing, as viewed from the side, having a generally pointed leading edge and two surfaces sloping back at equal angles from the point. When a standard razor-like blade is positioned in the knife, the midpoint of the blade between its sharpened cutting edge and non-sharpened opposite edge, lies on an imaginary line extending from the point at the forward end of the casing and generally through the center of the knife. The blade may be positioned with its cutting edge being on one side or the other side of the imaginary centerline. In either position, the cutting edge of the blade will project similarly from the casing when a thumb piece is pushed toward the forward end.

  • Cable stripper
    Patent number: 5009005
    Abstract: A cable stripping tool has a pair of jaws which can be closed together, one of which is formed with cruciform slots 14, 16, so that a cable can be supported in one or other of the slots. The other jaw carries a cutting tool aligned with the center of the slots, so that when the cable is so inserted and the jaws are closed, the tool will cut into the cable and then by pulling the cable along the length of its supporting slot 14, an axially extending cut can be produced into the cable sheath; or by rotating the complete tool about the cable when it is supported in the slot 16, an encircling cut can be produced. The position of the cutter relative to the center point of the cruciform slots can be adjusted angularly so as to keep the blade in the best position irrespective of the diameter of the cable involved.

  • Utility knives
    Patent number: 5005290
    Abstract: A utility knife comprises a lower elongate part shell 1 and an upper such part shell 3 forwardly fitted with interengaging wedging surfaces whereby they clamp together on relative longitudinal movement. This movement is achieved by turning nut 2 on shank 8 to bear on wall 30. The loosening of the nut 2 to unclamp the part shells and thus permit blade 43 to be pushed forward with slider 42 by pushbutton 41 does not separate the part shells 1 and 3 since the end spur 9 of the shank 8 still rides on arresting web 37. Maximum unscrewing of the nut, however, permits separation e.g. for access to stack of spare blades 60 resiliently held at 59 in the rearward part of shell 1 (now unencumbered by the conventional screw-shank), but does not lead to loss of nut 2 because of a complementary detent configuration 25 at the end of the shank and in the end wall 2a of the nut prevents complete nut/shank separation.

  • Spring operated impact tool
    Patent number: 4999914
    Abstract: A spring operated pinching device, which includes a housing defining therein a plurality of scoop channels for receiving an adjusting knob, an actuating member, a guide board member and a tool holder member, with a compression spring set between the adjusting knob and the actuating member, with a guide rod member and an eccentric spring set between the guide board member and the tool holder member, and with a board tool member fastened in the tool holder member. The downward pressing force of the housing against the board tool member forces the tool holder member to squeeze the eccentric spring permitting the guide rod member to insert through the guide board member into the actuating member so that the instantaneous expansion force from the compression spring forces the actuating member to drive the board tool member to connect a telephone wire to a wiring board by means of squeeezing process.
