  • Patent number: 7562518
    Abstract: A fluid activated connecting pin removal tool, includes a body defining a first cavity adapted to receive a portion of a work piece and a second cavity positioned substantially perpendicular to and intersecting the first cavity. When a fluid activated cylinder is mounted to the body in a first orientation relative to the second cavity, expansion of the fluid activated cylinder results in a piston extending from the cylinder into the first cavity in which the work piece is positioned to exert a force upon a connecting pin connecting portions of the work piece. When the fluid activated cylinder is mounted to the body in a second orientation relative to the second cavity, the secondary cavity serves as a storage compartment for the fluid activated cylinder.

  • Publication number: 20090107805
    Abstract: In one aspect, a modular link conveyor chain including slats is capable of assuming a compressed and an expanded condition so as to permit side-flexing while moving along a forward run and a return run in an endless path. The chain is formed of links arranged in rows spaced apart in the conveying direction, the links of a first row including aligned apertures and the links of a second row including oversized apertures, such as slots, for aligning with the aligned apertures of the links in the first row. A first connector is associated with the corresponding apertures to interconnect the first and second rows of links. At least one elongated slat is mounted to the connector. The slat maybe mounted for pivoting movement between a first position forming at least part of a conveying surface along the forward run, and a second position along the return run.

  • Patent number: 7441396
    Abstract: A method of manufacturing of power transmission chain 1 by interconnecting plural link plates 2 with pins 3. Individual pin pairs 3 are arranged and temporarily fixed to places. The link plates 2 are sequentially stacked in layers by press-fitting respective through-holes 4 of the link plates 2 about the respective pin pairs 3, whereby the link plates 2 are interconnected to form a circular chain (an endless loop). Subsequently, the individual pin pairs 3 are released from the temporarily fixed state. Thus, the manufacture of the power transmission chain 1 is decreased in the number of operation steps, so that the chain may be assembled easily.

  • Patent number: 7343728
    Abstract: A tool for aiding master link removal from a chain. The master link includes two pins and a clip with two ends extending from one pin to the other. The chain includes plates, pins, and rollers. The chain has a longitudinal direction along the length of the chain. The tool includes a support member, a plurality of coupler legs, and two pry posts. The coupler legs extend from the support member and are sized to fit between adjacent chain rollers. The legs, combined with the support member, bridge across the master link to hold it secure relative to the pry posts. The pry posts extend from the support member laterally offset from the coupler legs. The pry posts are generally laterally adjacent the ends of the clip when the coupler legs are secured to the chain.
