  • Patent number: 8166744
    Abstract: An articulating pin for the links of a bicycle chain, of the type capable to be inserted in aligned holes of an outer link and of the corresponding inner link of the chain, to hinge the links to one another, has a central portion and a distal portion. The distal end is elastically deformable for the insertion through the holes.

  • Patent number: 7721520
    Abstract: A highly durable and compact chain disconnecting and connecting tool that may be used for a chain at a sprocket part for winding the chain and that can receive an operational load at two places is provided. A first block has an engaged pressure actuating member coupling member. A second block is coupled with the first block turnably by the coupling member and has a cutout on one side and a through hole on another side of the block. The tool is attached to the chain from an opening while positioned engagement with an edge projection of a tap bolt that is screwed with the first block and with the cutout or the through hole.

  • Patent number: 7013631
    Abstract: The linked bracelet, in particular for a watch, comprises a metal hinged chain passing through a series of ornamental tubular links (4) made of ceramic material, each ornamental link (4) having at least one longitudinal passage (20), in which a metal link and a hinge associated with it are housed and can rest against an inside surface (26) of the base (27) of the ornamental link in the region of the hinge, when the hinge is in a folded position. A front face (23) of each ornamental link (4) has at least one raised section (34) located in the same region of the width of the ornamental link as said inside surface (26) where the hinge or the metal link rests, this raised section being arranged to abut against the opposite front face (24) of the adjacent ornamental link when the hinge is in said folded position. This arrangement balances the vertical force (F) exerted by the chain on the base (27) of the ornamental link at the right place and thus prevents any risk of fracture by transverse bending.

  • Publication number: 20030192299
    Abstract: A wear resistant chain, which smoothly articulates and slides for a long period of time without generating unusual wear elongation even if used together with an extremely deteriorated lubricating oil having a high degree of oxidation, has both ends of a bushing are force-fit into bushing holes of a pair of inner plates respectively and both ends of a connecting pin which is rotatably mounted into the bushing are force-fit into pin holes of a pair of outer plates disposed on both of the outer sides of the pair of inner plates. The bushing uses the base material of one steel selected from an austenite stainless steel, a martensite stainless steel, a precipitation-hardening steel, a high-carbon chromium bearing steel and an alloy tool steel each subjected to heat curing.

  • Patent number: 5966921
    Abstract: In order to provide a timing mark at a specific place on part of a timing chain in a manner in which the quality of the timing chain is maintained, a timing chain 4, made endless by outer plates 1 and inner plates 2 being connected by means of connecting pins 3 is provided with a timing mark 1' at a specific part on one side of an outer plate 1. The timing mark 1' is placed on the outer plate 1 between the connecting pins 3 and is in the shape of a web extending from an inner edge of the outer plate 1 to an outer edge thereof. The timing mark 1' is provided by baking a coating on the outer plate 1 after the timing chain has been assembled.

  • Patent number: 4123947
    Abstract: The present invention pertains to a non-metallic transmission chain for high loads which comprises a plurality of non-metallic links of a material having a tensile strength of at least 8500 psi and a plurality of associated glass fiber reinforced pins with a tensile strength of at least 1800 psi and flexure modulus of not less than 1,000,000 psi. The superior strength and qualities of the pin provide significant reduction in the undesired side arm flexing of the links.

  • Patent number: 4080782
    Abstract: A swivel having a socket, an eye element formed in a bifurcated manner and in retention of a terminal tool such as a hook element, and the socket forged with a clearance closure in retention of the eye element whereby the eye is free to turn and limitedly pivot but is restrained from removal from the socket. The socket is formed as a part of a chain binder or the like and is useable on either of or both the clevis and bar ends of such binders.
