With Tool Tensioning Means Patents (Class 83/581.1)
  • Patent number: 10369641
    Abstract: A blade clamp with first and second gripping members configured to hold a cutting blade, a lever connected to the clamp by a connection member, and a head that receives the connection member that extends through an aperture of the head. The connection member can move along a first axis through the aperture of the head and move the clamp along the first axis based on a position of the lever. The first and the second gripping members of the clamp can clamp the cutting blade along a second axis orthogonal to the first axis based on a position of the clamp along the first axis. The lever can include an eccentric cam surface that engages a cam follower. The eccentric cam surface can cause the clamp to provide a clamping force and tension to the cutting blade.

  • Publication number: 20130205958
    Abstract: The invention relates to a cutting device for cutting strips from a band of cord-reinforced unvulcanized rubber. The device comprises a frame, a first and a second cutting member having a substantially straight first and second cutting edge, respectively, of a hard metal, wherein the first cutting member is fixedly attached to the frame, and the second cutting member is substantially rectilinearly movable by means of a guide rail that is attached to the frame. The second cutting edge is movable along the first cutting edge for cutting the strips. The guide rail on the one hand is hinged to the frame parallel to the first cutting edge, and on the other hand is attached to the frame by means of a tensioning member. The tensioning member is adapted for providing a constant transverse force with which the guide rail is pushed to the first cutting edge. The frame further comprises a stop member for bounding the movement of the guide rail to the first cutting edge.

  • Patent number: 6725757
    Abstract: A scroll saw includes upper and lower driving arms, a saw blade, a blade retaining unit, push rod, a biasing unit, and an actuating unit. The blade retaining unit includes a pivot seat mounted pivotally on a distal end of the upper driving arm, and an upper blade holder mounted on the pivot seat. The pivot seat is pivotable relative to the upper driving arm from a first position, where the upper blade holder engages an upper blade end of the saw blade, to a second position, where the upper blade holder disengages from the upper blade end. The biasing unit provides a biasing force that pivots the pivot seat to the first position. The actuating unit provides a pressing force on the push rod to push the pivot seat to pivot to the second position so as to permit release of the saw blade.

  • Patent number: 6435068
    Abstract: A mechanism for cutting an elongated material, such as insulated wire or fiber optic cabling. The cutting mechanism includes a stationary blade housing that includes a recessed blade receptacle. The blade receptacle receives an insert blade that is biased outward by a bias element. A cutting blade having a pair of guide legs is movable relative to the stationary blade housing and insert blade such that a cutting edge of the cutting blade interacts with a cutting edge of the insert blade to sever the elongated material. The cutting blade is received within a blade guideway formed between the blade housing and an attached guide block. The blade guideway guides the movement of the cutting blade between its retracted position and its extended position. As the cutting blade moves to the extended position, the guide legs of the cutting blade contact an outer face surface of the insert blade such that the insert blade and the cutting blade retain the desired orientation.
