摘要:
An anchoring device for use in retaining a railway rail fastening clip having first and second leg portions and a rail-bearing portion therebetween. The anchoring device includes a base member, an opening in the base member configured to receive a fastening component for fastening the anchoring device to an underlying foundation, and first and second clip-retaining sides extending from said base member with the first clip-retaining side being spaced apart from the second clip-retaining side so as to define a space therebetween for receiving the rail-bearing portion of the clip. Each clip-retaining side comprising upper and lower clip contact walls defining a passageway for receiving one of the leg portions, wherein the leg portions contact the clip contact walls of the respective clip-retaining sides as the clip moves from a wedged position towards an engaged position where the rail-bearing portion of the clip bears on the rail.
