Abstract: An improved connector for coupling a chain to a wire rope or cable such that the resulting connection can be passed over a sheave, pulley, wheel or windlass without applying a bending stress to the wire rope. The connector comprises a hemispherical housing having an opening therethrough that is axially symmetric about the radius that is perpendicular to the planar portion of the hemispherical housing. The opening is adapted to accept and retain a wire rope having a terminal fitting by holding the terminal fitting within the hemispherical housing. A semi-circular member of common radius to the hemispherical housing and adapted to accept and retain a chain is attached to the planar portion of the hemispherical housing. A pair of retaining pins pass through the co-axial openings in the hemispherical housing and the end of the semi-circular member terminating on flat surfaces on opposite sides of the terminal fitting of the wire rope.

Abstract: A load binder having a shortened handle with means to receive and interlock with a separate extension member, which is also adaptable to release the load binder.

Abstract: A fitting for flexible fabric type web slings.

Abstract: A mechanically connected socket for `on-the-job` connection with structural strand includes a sleeve and an internal wedge shaped member through which the center core of the strand is received and retained while one or more outer layers extend longitudinally about the wedge and a bulbous head which, when assembled, encapsulates the strand.

Abstract: An improved connector for coupling a chain to a wire rope or cable such that the resulting connection can be passed over a sheave, pulley, wheel or windlass without excessive stress applied to the wire rope. A housing is provided having an axially symmetric opening through the housing with an exterior surface adapted to rest upon the outer peripherial portion of the windlass (or the like) as the connection traverses the windlass and wherein a retaining pin perpendicular to the axis of the opening at essentially the center of the housing holds a pair of rotatable U-shaped members within the housing for connecting the chain to the wire rope. Such a connection is particularly useful in coupling an anchor chain to a wire rope in anchoring systems.

Abstract: A hook assembly usable with conventional load lifting equipment has a frame and a generally arcuate hook member pivotally assembled to the frame. The hook member is rotatable relative to the frame between an open position for engagement of a load loop, such as a link or sling, a closed position to secure the load for handling, and a discharge position for dropping the load loop from the hook assembly. The frame has a contoured portion fashioned to cooperate with a hook member tip and body portion to define a closed, load retaining eye when the hook member is in the closed position, and an open, unobstructed throat when the hook member is in the open position. A releasable lock mechanism is assembled with respect to the frame and is operable to hold the hook member in an open position, to lock it in the closed position and to release to allow the hook member to move to the discharge position. The releasable lock mechanism includes a locking member fixed for guided movement relative to the frame.

Abstract: A coupling link having two half links, each half link comprising a U-shaped member, each of the ends of each of the arms of the U-shaped members having at least one ear. The plurality of ears each have an opening therethrough, the axes of the openings being substantially perpendicular to the arms of the U-shaped members. The plurality of ears are adapted to interact with each other so that the openings through the ears will be coaxial and will be adapted to receive a hardened steel pin which will lock the two halves of the link together. The pin is locked into position within the openings of the ears by means of a spacer which is adapted to fit between the ears and is in the form of a cylindrical spacer split along a diameter. The internal diameter of the spacer is substantially the same as that of the pin.

Abstract: A load indicator is connected between a load line and a load handling member such as a hook. The indicator includes a hollow cylindrical housing, a plunger assembly including a transverse head slidably mounted in the housing, a pilot rod integral with the head and extending to a location outside the housing, means connecting a first end of the housing opposite the plunger rod and means connecting the plunger rod to the load line and to the load handling member, and a compression spring in the housing urging the plunger head toward the first end of the housing. The wall of the housing has several sight openings therethrough. A sight band of contrasting color is fixed to move with the plunger assembly inside the housing and to be visible through the sight openings.

Abstract: A cylindrical metal pin used to connect and permit the relative rotation of two mechanical parts, is held and prevented from relative longitudinal motion by means of a flanged, slotted, locking collar and bushing.

Abstract: A device for connecting wire rope to a chain and comprising a wedge means adapted to be inserted into the center of one end of the wire rope for receiving the strands of the wire rope along the outer periphery thereof, said wedge means and rope strands receiving a socket member therearound whereby the rope strands are securely clamped between the wedge and the socket member, and a connector means threadedly engageable with the socket member and having pin means engageable with one link of the chain. The threading of the connector applies force against the wedge to increase the clamping pressure against the wire rope strands. The threaded end of the wedge provides a release means for easily removing the wire rope from the wedged connection.

Abstract: A hoisting hook carries an end loop of a load bearing line and has an eye, a curved hook with a hook tip spaced from the eye to form a throat therebetween, and a throat closure device in the form of a safety gate pivotally mounted for rotation about the eye of the hook. The gate has a bridging arm portion which, in closed relation, extends from the eye of the hook to the .[.top.]. .Iadd.tip .Iaddend.of the hook across the hook throat and a connecting arm portion which extends upwardly from the eye of the hook to provide a gate eye to receive a hoisting line. When the end loop of the load bearing line is on the hook and the hook and gate combination is loaded, the load on the hook will tend to cause the bridging arm portion of the gate to close on the tip of the hook and to remain in a closed position. A self-locking latch is pivotally mounted entirely within the gate for movement between locking and release positions.
