Abstract: A boltless two-piece rail fastening assembly for securing a railway rail, supported on a conventional tie plate, to a wooden cross tie is comprised of a chair and a rail clip latched thereon. The chair includes a body, having a jaw with a bight configured to receive the clip, and at least one downwardly projecting leg or shank for securing the chair adjacent the base flange of the rail. The rail clip is a torsional spring clip in the general form of an "S" having a rail-bearing leg for proximate engagement with the base flange of the rail and a tie bearing leg for proximate engagement with the tie plate.

Abstract: A main railway rail and a guard rail are maintained in spaced apart relationship on a tie plate having a shoulder located between the rails by an elastically deformed clip. The clip has two end lengths extending from opposite ends of a central length. One length of the clip rides on the main rail flange and the other length of the clip rides on the guard rail flange while the central length engages the intermediate shoulder.

Abstract: A compact, low profile, boltless, two piece railway rail fastening assembly for secring a railway to a conventional tie plate having spike holes enabling the tie plate to be affixed to a wooden cross tie. The assembly includes a drive-on, generally platelike, rail engaging, resilient, metal fastening clip coacting with a shoulder having a pair of anchor legs adapted for insertion through a pair of spike holes proximate the rail base flange so as to anchor the shoulder to the tie plate. The shoulder and rail clip cooperate to provide a positive interlocking relation which retains the clip against the rail base flange and secures the rail against movement under load.

Abstract: A drive-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 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 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 rail clip driven thereon in seating engagement therewith.

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.

Abstract: A separate insulator pad generally L-shaped in section, has a longer leg which is flat and which is held firmly between the inclined flange of the rail on one side and the inclined surface of the holding clip on the other side. The pad has upstanding shoulders on opposite sides in the direction of rail travel and the clip fits between the shoulders to prevent longitudinal slippage of the pad relative to the clip. The shorter leg of the pad extends snugly between the outer edge of the rail flange and a downwardly extending leg of the clip thus preventing lateral movement of the rail and at the same time, insulating the rail from the fastener structure.

Abstract: A one-piece spring-type rail anchor of substantially uniform wall thickness, for gripping the base of a rail having laterally projecting flanges, is comprised of a bowed throat portion, a pair of generally C-shaped members extending from opposing ends of the throat and adapted for engaging respectively opposite edges of the rail base, and a pair of bearing surfaces located at the junctures of the throat and C-shaped members for engaging the bottom of the base of the rail at spaced locations thereof, said rail anchor having a generally inverted U-shaped cross-section throughout.
