  • Automatic anchor applicator
    Patent number: 5142987
    Abstract: An automatic anchor applicator is provided having a frame which mounts a head assembly for vertical movement between a raised travel position and a lowered operative position. The head assembly has an inclined anchor conveyor and a pair of articulated applicator arms for transporting a pair of anchors from a loading station to a position adjacent a rail. Adjuster members are positioned immediately adjacent the pair of anchors at an adjustment station to shift the anchors along the rail into abutting relation with opposite vertical faces of the tie. Relative rotation of the articulated arms resiliently places the positioned anchors into positive engagement with the rail.
