Abstract:
Apparatus for securing interface strips to the sides of the rails at a road-rail crossing, wherein:the apparatus is suitable for use in conjunction with a rail and a pair of the interface strips, being a field-side strip and a gauge-side strip, one of which is located to the right side, and the other to the left side, of the rail; the strips have respective side-surfaces which, when the strips are fitted to the rail, face away from the rail; the apparatus includes a spring-clip, which is made of metal; the spring-clip is of a U-configuration, having a central beam and having left and right arms; the apparatus includes left and right tappets, which are arranged for contact with left and right tappet-receiving points on the side-surfaces of the strips; the apparatus includes a means for connecting the right tappet to a right tappet-receiving location on the spring-clip, and a means for mounting the left tappet at a left tappet-receiving location on the spring-clip; the means for connecting the right tappet to the right tappet-receiving location is of such a structure that the distance between the right tappet and the right tappet-receiving location can be adjusted in a directional sense towards and away from the left tappet; the apparatus includes an operable adjustable lock for adjusting the distance between the right tappet and the right tappet-receiving location; and the structure and springiness of the arms and the beam of the spring-clip are such that the arms are capable of being deflected apart a deflection-distance DDef without taking a permanent set, the deflection distance DDef being at least 12 cm measured along a line joining the left and right tappet-receiving locations on the arms.
