  • Patent number: 6443795
    Abstract: A transmission chain includes a plurality of unitary chain links, each of which has parallel first and second side plates, first and second connecting pins, first and second pivot pins, and first and second pivot seats. The first and second pivot pins of one of the chain links are connected pivotally, removably and respectively to the first and second pivot seats of an adjacent one of the chain links, so as to enable the transmission chain to possess the characteristics of an adjustable chain length.

  • Patent number: 6334828
    Abstract: A power transmitting silent chain apparatus comprises a silent chain and a sprocket. The silent chain is comprised of a plurality of link plates interconnected by connector pins. Each link plate has a pair of teeth. The sprocket has a plurality of involute teeth for meshing with the link plate teeth. The link plate teeth have inner and outer flanks profiled to satisfy the expression Hi=Ho+Hs, where Hi is a distance from a pitch line of the chain to a pitch line of the inner flanks, Ho is a distance from the chain pitch line to a pitch line of the outer flanks, and Hs is an amplitude of a polygonal motion of the chain.

  • Patent number: 5288278
    Abstract: A bicycle chain having link plates connected to be oscillatable relative to one another within a predetermined range of flexion. To determine the range of flexion, outer link plates include engaged members, and inner link plates include engaging members for engaging the engaged members. A maximum range of flexion of the chain is determined by contact between the engaged members and engaging members. This maximum range of flexion is determined to enable the chain to be wound around the smallest pulley of a speed changer or derailleur.

  • Patent number: 4750325
    Abstract: A chain link having a pair of curved extremities and being generally in the shape of an elongated loop. The loop defines two sides which converge towards the middle of the link where the two sides are rigidly jointed together, as by a weld, thereby forming a pair of interior spaces progressively narrowing towards the middle. Such link is adapted for use in alternation with pin links in a chain designed to remove waste material in a livestock enclosure. A method of making the link is further disclosed.

  • Patent number: 4610647
    Abstract: A connection for use with chain links includes a main body portion which has at least one and preferably two support bars extending outwardly from each side of the main body portion, a recess or groove in the support bar adjacent its distal end spaced from the main body portion a distance to allow a plurality of chain links to be mounted thereon in spaced relationship, a securing clip located within each recess or groove to retain the chain links in position on, and relative to, the support bars with faces being adjacent, and one or more raised portions on at least one face of the chain links to space the chain links apart.

  • Patent number: 4428740
    Abstract: A variable ratio transmission apparatus for converting an input torque at a first RPM to an output torque at a second RPM includes a pair of driving discs disposed on an input drive shaft and in spaced parallel relationship thereto, a pair of driven discs disposed on an output drive shaft and a continuous length of metal link chain extending around and in direct contact with each pair of discs so as to create a high frictional force at the discs and chain interface sufficient to transmit motion from the driving discs to the driven discs. The link chain is arranged as a continuously repeating pattern of link plates which are interconnected by pins and a plurality of U-shaped drive members assembled relative to the link plates and pins. The outwardly facing surfaces of each drive member are contoured so as to conform to the surface shape of the driving and driven discs such that the chain is able to move in and out according to disc spacing, thereby realizing different radii.
