  • Publication number: 20100050590
    Abstract: A device for fastening emergency equipment to a vessel includes a hydrostatic release mechanism, a tether, and a float-free link. The tether is attached to the hydrostatic release mechanism and provides an attachment point for lashing the emergency equipment to the vessel. The tether may also be threaded through openings in the curved partially tubular body of the float-free link. A breakable bridge is integrally coupled to the body of the float-free link to form a closed loop. The breakable bridge is designed to be the break point when the emergency equipment needs to be freed from a vessel that has sunk below a predetermined depth. When the vessel sinks below the predetermined depth, the hydrostatic release mechanism severs the tether thus freeing the emergency equipment from one point of attachment to the vessel. The bridge is designed to break when the strain on the fastening line, e.g., the painter line, is between a predetermined minimum force and maximum force.

  • Patent number: 7237376
    Abstract: A system for repairing a continuous loop chain includes a plurality of pairs of chain links, each link having a pair of straight, substantially parallel side bars. Each pair of chain links has an outer link having a first width between the outer link side bars, and an inner link having a second width between the inner link side bars. The second width is less than the first width such that the side bars of the inner link are adapted to fit between the side bars of the outer link. The outer links and inner links are pivotally joined to each other. A repair link having a pair of offset side bars is adapted to connect on one end to the inner link of one of the pairs of chain links and on the other end to the outer link of another one of the pairs of chain links.

  • Patent number: 7195116
    Abstract: A link chain has multiple individual chain links arranged in a repeating sequence. A first chain link has two shank portions connected by two arc portions which define an interior space. One or more dividing elements project inwardly from an inside surface of a shank portion and divide the interior space into two movement spaces. A second chain link has two shank portions connected by two arc portions which define a movement space within its interior. The second link is linked to the first link and movable within one of its two movement spaces. When a longitudinal axis of the second chain link is moved from an intended, substantially aligned position by less than 90 degrees, an outside of an arc portions of the second chain link that engages a movement space of the first chain link contacts the dividing element, and an inside of a shank portion of the second chain link contacts an arc portion of the first chain link.

  • Patent number: 7117575
    Abstract: In manufacturing a link plate for a roller chain, a band of sheet steel is intermittently forwarded along a path past series of dies, including rough punching dies and shaving dies. The punching dies and corresponding shaving dies are located symmetrically on opposite sides of an intermediate location along the path. The intermediate location coincides with a location at which the lateral deviation of the band reverses. Consequently, the outer peripheral surfaces of the plate and the inner peripheral surfaces of the connecting pin holes, both being formed by rough punching, are brought into very close alignment with the shaving dies.

  • Patent number: 7065952
    Abstract: The present invention discloses a chain where, upon the stressing of the chain, the links automatically arrange themselves with respect to one another in terms of their position in the chain, preventing any undesired link. A link can be developed in the form, in top view, of a drop or in the form of a keyhole. The described chain is not only suitable for application in lashing loads, but also for use with the manipulation of all accessory chain parts, in which the placement of a link is required, for example shortening hooks, shortening straps or the like.

  • Patent number: 6890278
    Abstract: A chain is provided in which adjacent links are attached to one another by a coupling pin that permits the links to rotate relative to one another on a connecting axis defined by a coupling pin. The links have movable link plates and can be fixed against relative rotation or released, at least on one side of the chain, by selectively engaging or disengaging the link plates. In one embodiment a restoring force urges movable link plates outwardly on both sides of the chain, toward locking engagement with the plates of the next adjacent links. The movable link plates are depressible against the restoring force, sufficiently to permit the adjacent link plates to overlap and pivot freely. The couplings between links can be switched between fixed and free rotational states by passing them through a path with converging walls that depress the movable link plates.
