Abstract
A drive chain comprises a plurality of inner links (1) interconnected by intermediate outer links and elongate pins (7) that are received in apertures in the inner and outer links. There is substantial clearance between the outer link and the corresponding inner links so as to permit flexion of the adjacent elongate pins in a direction substantially parallel to the length of the chain. The outer link may be in the form of a separate plate (6) or may be an integral part of the pins. In one embodiment the outer link is a crimped plate that offers resilience in the direction of the chain. The drive chains provide for shock absorption.

7437870 - Chain link plate with high strength - Owned by KMC Chain Industrial Co., Ltd. (Tainan Hsien,TW)

A chain link plate includes an elliptical plate body having opposite first and second surfaces, and two mounting holes spaced apart from each other in a longitudinal direction of the plate body and extending from the first surface to the second surface. The plate body has a central longitudinal line that passes through centers of the mounting holes, and two transverse lines that pass respectively through the centers of the mounting holes and that are perpendicular to the central longitudinal line. The plate body has an intermediate juncture portion defined between the transverse lines, and opposite end portions integrally and respectively connected to opposite ends of the intermediate juncture portion. The intermediate juncture portion has a largest width greater than that of each of the end portions.

7316169 - Load bearing device including overload indicator - Owned by Peerless Chain Company (Winona, MN)

Load-bearing devices, each including an overload indicator of the present invention interconnecting load bearing connectors, preferably elongated load bearing connectors are provided. In preferred embodiments, the load bearing connectors are chains, ropes, wire ropes, cables, straps and the like, preferably chain. The wire form overload indicator preferably includes a modified wire form link, preferably either a modified welded link or a modified quick link, generally having a first thickness and first and second elongated sides. The modified link preferably includes two elongated sides, one of which preferably has a portion having a diminished thickness narrower than the first thickness. The diminished thickness preferably has a generally predetermined load bearing capacity or capability and is calibrated to reduce the load bearing capacity or capability of the overload indicator. Methods of making an overload indicator and a load bearing device including an overload indicators of the present invention are also disclosed.

7032466 - Load bearing device including overboard indicator - Owned by Peerless Chain (Winona, MN)

A load-bearing device including an overload indicator and a wire form overload indicator are provided for interconnection of load bearing connectors, preferably elongated load bearing connectors, for bearing a load. In preferred embodiments, the load bearing connectors are chains, ropes, wire ropes, cables, straps and the like, preferably chain. The wire form overload indicator preferably includes a wire form quick-link having a first thickness, and first and second elongated sides. The first elongated side preferably includes an interconnectable gap through which connection loops of the load bearing connectors can pass when the interconnectable gap is unconnected. The interconnectable gap includes a connection end and a connectable end, the connecting end having a connector capable of connecting the connecting end to the connectable end to close the gap. The second elongated side preferably has a portion having a diminished thickness as compared to the first thickness. The diminished thickness preferably has a predetermined load bearing capability and is calibrated to reduce the load bearing capability of the methods of making an overload indicator and a load bearing device including an overload indicator are also provided.

7571595 - Chain link overlay and method of improving chain link aesthetics

A chain link overlay and method of improving chain link aesthetics. The chain link overlay is designed to be permanently attached to a chain link. The overlay has an overlay front side with adornment, coloration, art work, or embossment, and also an overlay rear side which is intended to be attached to a chain link. The overlay rear side includes a pin head bore corresponding to each pin head extending from the chain link. When the overlay is attached to the chain link, each pin head extending from the chain link is disposed within a pin head bore. The overlay may be attached to the chain link with adhesive, solder, welding, or any other appropriate means of attachment. The overlay front side may feature artwork, coloration, decoration, and/or embossments, to increase the aesthetic appeal of a chain link to which the chain link overlay has been attached.
