摘要:
This invention relates to a device for securing a rail to a railroad tie, and wherein a base plate is provided with guide ribs for abutting the rail foot. The base plate is secured to the tie and the guide ribs provide anchorage openings wherein anchors may be introduced into the anchorage openings for clamping the rail foot to the base plate. A resilient rail attachment with no threaded connections is obtained by the provision of extension arms integrally formed with the anchors and projecting beyond the rail foot. The anchors are disposed on both sides of the rail and resilient clamping elements are positioned in the longitudinal direction of the rail into channels formed between the rail foot and the extension arms. The clamping elements are subjected to deformation and supported under tension between the rail foot and the extension arms.
