ABSTRACT:
An elastic rail clamp (10), for fastening a rail to an underlying rail plate or rail tie (1). The clamp is of the type comprising a pair of substantially parallel members (19) folded into a D configuration so as to have a front toe portion (16) adapted to seat on a flange of the rail, which toe portion is formed by respective free end regions (18) of the substantially parallel members, and to also have a base portion (11) adapted to seat in a slot (4) in the rail plate or a shoulder secured to the rail tie. The clamp is shaped such that the parts (14) of the substantially parallel members between the base portion (11) and the toe portion (16) are tapered in external dimensions towards the toe portion of the clamp, and the free end regions (18) of the substantially parallel members are turned back toward a rear portion (13) of the clamp and project outwardly so as to abut a portion of the rail plate or of the shoulder secured to the rail tie when the clamp is in use, thereby to prevent the clamp from sliding off the rail flange. Alternatively or in addition, the pair of substantially parallel members (19) are joined together by a web (13) between the toe portion (16) and the base portion (11).
