  • Patent number: 10710143
    Abstract: A method for creating a termination by attaching some kind of fitting to the end of a tensile member such as a cable. The end fitting is provided with one or more internal cavities. Each cavity has a proximal portion that is adjacent to the area where the tensile member exits the fitting and a distal portion on its opposite end. A length of the tensile member's filaments is placed within this expanding cavity and infused with liquid potting compound. The method exploits the characteristic of a liquid potting compound as it transitions to a solid. During the solidification process tension is applied. The resulting linear displacement tends to pull the filaments residing in the potting compound into better alignment and improve load sharing.

  • Patent number: 7325360
    Abstract: A cable tensioner includes two members, such as a pipe and a tube, that define a cable path. The members are helically mobile relative to each other. A retractable detent permits the relative movement of the members in one direction and prevents the relative movement of the members in another direction. The cable tensioner is thus irreversible, regardless of the operating conditions. The cable tensioner is, for example, applicable to a cable used in a vehicle window regulator. The window regulator cable extends in a protective sheath. One end of the protective sheath abuts against the second member, and the second member acts on the end of the protective sheath to increase the cable path and cable tension.

  • Patent number: 4567627
    Abstract: A load binder or lashing tightener is provided made up of a first inner elongate sleeve member closed at one end, an anchor fitting on said closed end, a thread nut in the other end of said first sleeve, a second outer sleeve having one end adapted to telescope over the first inner sleeve, an anchor member on said second sleeve adjacent the other end, an elongate screw extending through the second sleeve, one end threadingly engaging the nut in said first sleeve, the other end rotatably fixed in the said other end of said second sleeve, a drive on said other end for rotating said screw whereby said second sleeve is caused to telescope over the first sleeve and the anchors on said sleeves are brought together and an anchor member at the said one end of said second sleeve adapted to receive the lashing to be tightened after the sleeves have been telescoped. The drive may be a hand knob protected by a spacer ring on the second sleeve.

  • Patent number: 4560147
    Abstract: A U-strap mounts a nut between the legs of the strap for rotation perpendicular to the longitudinal axis of the strap. The nut is provided with a threaded bore which threadably receives an adjustment sleeve. The adjustment sleeve is also threaded internally reversely to its external threads and threadably receives a stud connected to or constituting a first member to be placed under tension with respect to a second member coupled to or constituting the strap. The turnbuckle is particularly useful in mounting standard wire or rod rigging on a sailboat or sailing yacht.

  • Patent number: 4367862
    Abstract: A roller chain-connecting tool comprises a narrow elongated body containing a lengthwise-extending threaded rod journaled in and extending through both ends of the body to hexagonal bolt heads for rotating the rod. A chain hook is mounted on the threaded rod by means of an internally threaded block which moves lengthwise along the tool's body when the rod is turned. In one embodiment, a second chain hook is mounted on one end of the body and the rod is threaded in only one direction. In another embodiment, the second chain hook is mounted on another internally-threaded block and the threaded rod has approximately one half threaded in each direction from its center. The chain hooks or jaws are gently curved toward one another and are tapered so as to fit both small and large gauge roller chains, the large chains being at least twice the size of the small chains.

  • Patent number: 4345740
    Abstract: A system for tensioning stranded or wire cables in prestressed concrete comprises an anchoring head having holes in which are anchored the strands or wires. The anchoring head has a ring in screw-threaded engagement with an exterior surface of the head for providing a reactive support for the anchoring head. An intermediate member is releasably fixed to the anchoring head by rods which extend through holes in the intermediate member and are in screw-threaded engagement with the anchoring head. The intermediate member also has a screw-threaded exterior for engagement with the ring to allow the ring to provide a reactive support for the intermediate member at intermediate stages in a tensioning operation.The intermediate member is releasably connectable to a tensioning jack thus allowing the jack and the intermediate member to be removed from the anchoring head once tensioning is complete.

  • Patent number: 4247009
    Abstract: A fastener for securing pipes to a rack includes a tensioning mechanism, a bracket for mounting the tensioning mechanism to the rack, and a flexible cord. The tensioning mechanism has a tubular housing, a threaded shaft mounted in the housing to rotate about its longitudinal axis while being fixed axially, and a movable bracket threaded on the threaded shaft and mounted in the housing so that it will move up and down along the length of the housing in response to rotation of the threaded shaft. The flexible cord has one end fixed to the mounting bracket and knots spaced along a portion of the length of the cord adjacent its free end. The cord is wrapped around the articles to be held on the rack and one of the knots in the cord is selectively and releasably positioned in a notch in the movable bracket. Rotation of the threaded shaft in one direction will cause the cord to tighten about the articles and rack to fixedly secure the articles to the rack.
