Abstract: A rail fastening assembly for securing a railway rail to a support therefor, comprising a retaining chair secured to the rail suport, such as a tie. The retaining chair includes a head having an inner side and an outer side with a recess formed in the head. An S-shaped torsional spring rail clip having a central leg is received in seating engagement in the recessed head of the retaining chair, with the terminal legs of the clip coacting with respectively a ramp on the retaining chair and a base flange of the railway rail, for establishing a torsional spring force on the central leg of the clip, and securing the railway rail to the support. The recess in the head is disposed on the outer side of the head facing away from the rail. In one embodiment an insulator is disposed intermediate the base flange of the rail and the terminal leg portion of the clip that holds the rail in place, for electrically and mechanically insulating the retaining chair and the rail clip from the rail.

Abstract: A rotatable or twist-on rail fastening assembly for securing a railway rail to an anchoring support therefor is comprised of a generally S-shaped torsional spring rail clip and a post-type mounting or chair adapted to cooperate therewith. The rail clip includes a central leg, a tie anchor portion and a rail bearing portion comprising a pair of loops spaced on opposite sides and extending from opposite ends thereof, each of the loops including an arcuate and a terminal leg. The chair is adapted to have the one loop of the S-shaped clip rotated around the post.

Abstract: A device for deterring the overturning of railroad rails comprised of a generally C-shaped boltless clip for restraining the upward movement of a rail base flange. The clip is disposed within an existing spike hole in a conventional railroad tie plate with its upper arm positioned in partially overlapping, spaced relation to the rail base flange and its lower arm, which is formed into a catch, in anchored engagement beneath the tie plate and wedged into the tie supporting the rail. In the presence of rail overturn forces, the clip couples the rail base flange to the tie plate.
