  • Patent number: 5173998
    Abstract: A hook for gripping chain is asymmetrical so that the effective chain length can be adjusted to a part link tightness. The attachment end of the hook is offset from the plane of the hook end, which includes the slot for receiving a link of a chain. If the chain enters from one side of the hook, the chain and hook have a different angle than when the chain enters from the other side of the hook. The resulting change in angle and hence the way the hook interferes with the chain changes the length of chain required for the chain to reach the slot.

  • Patent number: 4617703
    Abstract: A device for tightening chains, cables or ropes is disclosed. Previously, turnbuckles or load binders, the latter operating on the principle of the lever, have been used to tighten two ends of a chain or cable around an object, or the ends of two chains which have been secured at their other ends. Such devices are hand-operated and accordingly can only apply limited tension to the chain or cable. The present invention provides a device whereby an air-gun or pneumatic wrench or other power tool can be used to tighten the chain or cable to much greater tension. The device utilizes a threaded bolt which is secured to one end of the chain and which, by the rotation of a threaded socket, is drawn through a sleeve to which the other end of the chain is secured, thereby tightening the chain.

  • Patent number: 4507829
    Abstract: A buckle intended for use primarily with wide, flat strapping material used in the air cargo transportation industry. The buckle has a body member and an "over-center" handle member journaled on a journal pin attached thereto such that the handle member acts like a lever and the journal pin as a fulcrum in tensioning the strap. With the buckle in the open position, the strap is fed into the buckle and looped around the journal pin. Rotating the handle member to the closed position causes a load pin attached to the handle member to impact the strap and deflect its path in the buckle, thereby pulling the strap taut under considerable torque load. In the prior art buckles, two load pins were required to apportion that torque load between them to keep the strap from slipping as the load pins could rotate at high torque loads. The need for two load pins is eliminated in the present invention by using only one load pin which is attached in such a way that the pin cannot rotate, even under such high torque loads.

The binder employs a handle for tensioning and releasing the binder. The handle and lever element are constructed so that the handle positively engages the lever element to pivot the lever element on the tensioning stroke. However, the handle is employed merely to trigger the release stroke by rotating the lever element through dead center while the handle is out of the path of travel of the lever element. Because of this feature, the user is not endangered by a "flyback" of the handle when the binder is released.

Each winch is rotatably mounted between the top and bottom walls of its base and tension of the tie-down chain is maintained by a pawl and ratchet. The winch block has a chain pocket to lock a horizontal link of the chain to the chain pocket and a recessed portion engaging a next adjacent vertical link of the chain. The ratchet has a cooperating pocket engageable with a next adjacent vertical link of the chain and completing the chain pocket in the winch block. The chain may be trained through one end or the other of the base for the winch.

  • Patent number: 4211389
    Abstract: Apparatus for binding a load of articles including an elongate cable extending about the load, and a spring-loaded device operatively interconnecting opposite ends of the cable. A cable take-up drum is provided to adjust the effective length of the cable extending about the load and to deflect the spring to provide selected tightening of the cable about the load. Should the load change configuration the spring maintains the cable taut about the load.

  • Patent number: 4143600
    Abstract: A chain attachment structure interconnects the end of a chain to the takeup drum of a winch or hoist so that the chain load is applied directly to an integral part of the drum even if the chain is fully unwound. A recess extends inward from the periphery of the drum and includes a pair of spaced walls. A lug integral with one wall extends toward the opposite wall. The space between the lug and the opposite wall defines a path for inserting a chain link into the recess and over the lug. A keeper inserted into the path prevents removal of the link from the lug.

  • Patent number: 4129285
    Abstract: A chain for binding logs on a transport platform may be fabricated from a plurality of sequentially connected generally planar links, each link having laterally directed, log-penetrating extensions mounted to its external sides and having an elongated member with two log-penetrating ends rigidly mounted between the sides of the link normal to the plane of the link. A combination of the chain with an over-center binder attached to said chain and having a chain-engageable first end is also disclosed.

  • Patent number: 3974544
    Abstract: The load binder, of any conventional type, has a length of security chain permanently attached to the same and carrying a shackle, ring or the like at its free end. A separate length of binder chain is provided having links that pass freely through the security chain and shackle; at one end a grab hook is connected to the binder chain and is of larger size than the noted shackle to preclude removal of the security chain at this end of the binder chain, while the other end of the binder chain is welded or permanently fastened at a point on the cargo transporter with which the binder is used. Accordingly, when thus installed on a flatbed or the like, the binder is normally permanently attached to the bed although adjustably positionable to the limits allowed by movement of the security chain along the length of the binder chain.
