  • Patent number: 4453291
    Abstract: A grip for cable, especially fragile cable such as fiber optic cable having a fragile connector at one end thereof. The grip comprises an elongated, hollow protective sheath with an open rearward end for receiving the connector therein, a pulling device coupled at the forward end of the sheath by means of a forwardly tapered nose piece and an open mesh sleeve coupled at the rearward end of the sheath for engaging the cable upon a longitudinal stretching thereof which radially reduces the sleeve around the cable. The pulling device comprises a shaft journalled for free rotation on the nose piece by ball bearings mounted in the nose piece to allow the sheath to rotate about its longitudinal axis as it is being pulled.

  • Patent number: 4368910
    Abstract: A grip for pulling cable, especially fragile cable such as fiber optic cable. The grip can pull such fragile cable with or without a fragile connector at the end thereof. The grip comprises a rigid, hollow protective sheath with an open tail end for receiving the cable end therein, a pulling device coupled at the lead end of the sheath, and a braided open wire mesh sleeve coupled at the tail end of the sheath for engaging the cable upon a longitudinal stretching thereof which radially reduces the sleeve around the cable. The pulling device can be a flexible wire loop rotatably coupled to the protective sheath. The open wire mesh sleeve can be closed along its length, split along its length or both closed and split in the two sections along its length.

  • Patent number: 4293157
    Abstract: A cable grip adapted to enclose a cable and comprising a split sleeve of open meshed structure with two series of loops along the two free longitudinal edges and a flexible locking member having a central loop and two legs extending from that loop for interconnecting the interfingered series of loops. The central loop is received in two adjacent loops at one end of the two longitudinal edges, and the legs extend through each of the remaining interfingered loops and are coupled together at the other end of these edges. To form the closure for the split sleeve, the sleeve is first wrapped around the cable so that the two series of loops are interfingered except for two adjacent loops at the top end, a rigid pin is maneuvered through all but the two top loops, the flexible locking member is maneuvered through these top loops and secured to the pin, and the pin is withdrawn, pulling the locking member with it through the remaining loops. Then, the locking member is released from the pin and is fastened in place.
