Abstract: A chain particularly useful for draglines in various type strip mining operations is disclosed. The chain is made up of individual, separately assembled links of generally a U-shape having spaced pin lugs at one end. The lugs have aligned pin eyes for holding a pin between them, which is received generally flush with the outside surfaces of the lugs. To prevent pin rotation and to prevent oblong wear in the pin eyes, the pin and the eyes have a flat surface on the side toward the open end of the U-shaped link. With the pin installed in the eyes, a keeper is welded onto the flat surface of the pin, extending between the two lugs to retain the pin in place. The units are assembled at 90.degree. to one another, with a pin of one link passing through the next link. The body of the link may be of a more wear-resistant material than the pin so that the easily replaceable pin wears out first.

Abstract: A tire or similar chain shackle connector having an inlet for receiving links to be connected, the end of the chain at one side of the inlet being solid and at the other side having holes for receiving a connector, and a closure member having a recess for receiving the solid end of the shackle and apertures or holes at the other end of the closure member through which the connector can be inserted.

Abstract: A spring clip is capable of selective installation on and removal from a pair of adjacent pins in a roller chain. The spring clip has a body portion formed of sheet spring metal and an opening at each of its opposite ends. The intermediate section of the body portion is preformed into an arc to establish a predetermined linear distance between the openings. The openings may only be simultaneously received by and installed at recesses at the extended ends of each pin by deforming the arc of the intermediate section to alter the distance between the openings to a magnitude generally corresponding to a predetermined distance between the pins. When both openings are simultaneously installed at the recessed portions of their respective pins, the arc of the intermediate section tends to re-establish the predetermined linear distance to prevent inadvertent removal of the spring clip from the pins.

Abstract: A wear-resistant link for tire chains, including a link body having at least one link opening between a running surface and a tire engaging surface for engagement with at least one connecting link. The surfaces defining the link opening merge with an outside area of the link body for forming an insert opening on this outside area. The wear resistant link is furthermore provided with at least one lock for the insert opening which lock includes at least one bolt or the like in engagement with the link body. The insert opening is located between the running surface and the tire engaging surface of the link body, and the lock is provided with at least one engaging surface. The arrangement is such that the respective link opening or openings in closed condition is or are defined by at least one engaging surface for engagement with the pertaining connecting link when the respective tire chain equipped with the wear resistant link is in operation.

Abstract: A device for adjusting the length of a link chain comprising a shackle or yoke in which the space between the arms is relatively wide except for a narrow portion at the closed end of the shackle. A length of chain extends through the space between the arms and is capable of moving lengthwise when in the relatively wide portion of the space. The relatively narrow portion of the space is wide enough to receive a link of the chain but not wide enough to permit the chain to move in a lengthwise direction. A pivoted keeper is adapted to project into the relatively wide portion of the space to retain the chain in the narrow portion and thereby prevent it from moving lengthwise.

Abstract: A shackle component for use in a fishing trawl in the form of a pair of shackles or clevises arranged in back-to-back relationship with the free ends of the arms of each extending away from each other, each of the arms of each shackle being apertured to receive a connecting pin and at least one of the arms of each shackle having a further aperture therein to receive a locking pin to hold the connecting pin in place.

Abstract: A link component for use in trawling gear which is made of metal and has at one end a closed loop, the other end having two projecting arms which, together with part of the loop, provide a clevis or shackle, the arms of which have apertures to receive a connecting pin for connection to an end link of a chain and wherein the loop is sufficiently wide at its end remote from the shackle to receive a pair of couplers for two wire ropes or chains and wherein at least one of the wide pieces of the closed loop is provided with a recess or flat sufficiently wide to enable a hook of predetermined size to be hooked onto the loop provided the throat of the hook is correctly orientated.

Abstract: A Kelly's Eye component for a fishing trawl is disclosed, the component being formed of metal and having one end in the form of a ring defining an aperture which is sufficiently large to allow passage of a trawl rope, the other end of the component being in the form of a shackle, the two arms of which are apertured to receive a connecting pin and at least one of the arms having a further aperture therein extending at right angles to the first aperture and arranged tangential thereto to receive a locking pin so that an end link of a chain may be connected to the shackle.

Abstract: In a shackle the shackle arms are bored to receive a pin and the pin and the bore through which the pin first enters, are shaped so that a plate, initially convex toward the pin may be flattened over the end of the pin and anchor itself in recesses in the shackle to retain the pin.

Abstract: A lift chain including an end connector for connecting an end link to the load-carrying member of a fork-lift truck or similar load-handling device. Each link of the chain comprises a plurality of juxtaposed parallel link plates and the end connector includes a clevis joining the end link with a head having a screwthreaded attachment stud. The clevis is pivotally connected to the end link and the head by means of two spaced connector pins disposed crosswise to permit the end link to swing omnidirectionally relative to the head.
