  • Patent number: 5288016
    Abstract: A rail-tie fastening assembly for connecting a rail to a tie including a rail seat assembly and a rail anchor. The rail seat assembly is connectable to the tie and the rail seat assembly includes a seat hook assembly which extends over a portion of the rail flange. A portion of the rail seat assembly is formed on a first radius to provide a rail seat curved bearing surface. The rail anchor has an anchor hook assembly which extends over a portion of the rail flange. The rail anchor has a portion formed on a second radius to provide a rail anchor curved bearing surface. In the assembled position of the rail seat assembly and the rail anchor, the rail seat curved bearing surface engages the rail anchor curved bearing surface to form a rocking bearing seat.

  • Patent number: 5165599
    Abstract: A rail-tie fastening assembly for connecting a rail having a rail flange to a tie comprising a rail seat assembly and a rail anchor. The rail seat assembly is connectable to the tie and includes an anchor slot and a seat hook assembly. The seat hook assembly is adapted to extend a distance over an upper surface of the rail flange. The rail anchor includes an anchor hook assembly adapted to extend over on the upper surface of the rail flange in an assembled position of the rail anchor to the rail seat assembly. The rail anchor is insertable through the anchor slot in the rail seat assembly to the assembled position. The seat hook assembly is spaced a distance from the upper surface of the rail in the assembled position of the rail anchor to the rail seat assembly. The anchor hook assembly engages one side of the rail flange and the seat hook assembly engages the opposite side of the rail flange to restrain lateral movement.
