  • Patent number: 4795091
    Abstract: An adjustable railway fastening for securing a bridge girder or cover plate of the girder to a cross-tie on a bridge which includes a resilient clip having a planar body portion with an elongated slotted opening therein for a bolt which is offset with respect to the resilient end engaging bridge girder. The resilient end in the form of a compression arch engages a girder flange to limit vertical movement and a tie-engaging end includes downwardly and outwardly extending ears for laterally restraining the cross-tie. A shoulder on the resilient end also engages a side of the girder flange to further limit lateral movement. In order to provide greater resilience, the arch includes two separate finger portions joined at the base with the body portion to form a U, each of the finger portions having a lip adapted to overlie the girder flange. A plate has an aperture for receiving a bolt and a projecting lug adjacent to the aperture to facilitate securing a bolt tensioning member, i.e., a nut.

  • Patent number: 4687134
    Abstract: A railway fastening, especially adapted for securing a bridge girder or cover plate of the girder to a cross-tie on a bridge, or like supporting structure, is in the form of a resilient clip having a substantially planar body portion with an opening for a bolt which is offset with respect to the resilient end engaging bridge girder. The resilient end in the form of a compression arch engages a girder flange to limit vertical movement and a tie-engaging end includes downwardly and outwardly extending ears for laterally restraining the cross-tie. A shoulder on the resilient end also engages a side of the girder flange to further limit lateral movement. In order to provide greater resilience, the arch can be in the form of two separate finger portions joined at the base with the body portion to form a U, each of the finger portions having a lip adapted to overlie the girder flange. A projecting lug adjacent to the opening for the bolt is provided to facilitate securing a bolt tensioning member, i.e., a nut.
