摘要： In a railway rail fastening clip (10), for use on a railway rail baseplate (40) of the K-plate type, comprising an elongate member bent such that first and second end regions (11, 12) of the member form respective lower and upper limb portions, the lower limb portion (11) forming a base portion (19) of the clip (10) for engaging a slot (31) in the baseplate (40) and the upper limb portion (12) extending further than the lower limb portion to form at its free end a toe portion (15) of the clip (10) for bearing on a rail foot (65). The toe portion (15) is not bifurcated and the width of the toe portion (15) of the clip (10) is narrower than the width of the upper part (31a) of the slot (31) in the baseplate (40) whereas the width of the lower limb portion (11) of the clip (10) is broader than the width of the upper part (31a) of the slot (31) in the baseplate (40). The clip (10) is retained in the slot (31) by means of a device (20) comprising a plate portion (21) for location on the rail foot (65), the plate portion (21) being provided with an abutment surface (23') for abutting the toe portion (15) of the clip (10).

摘要： In a resilient railway rail fastening clip (9) comprising firstly a substantially straight first portion (1), then a bent second portion (2), then a substantially straight third portion (3) the axis of which makes an angle substantially more than 45° with the axis of the first portion (1), the two axes lying in the same plane as one another, then a fourth portion (4) which is a reverse bend, then a fifth portion (5), then a sixth portion (6) which is another reverse bend and finally a seventh portion (7), the first portion (1) is formed so as to comprise a region (1B) having a generally cylindrical surface extending along its entire length and a longitudinally-extending part (1A) having a surface which is less convex than the generally cylindrical surface region (1B) of the first portion (1). At least part of the second portion (2) and at least part of the third portion (3) are preferably manufactured with substantially flat surfaces (2A, 3A) on respective lateral regions thereof which contact the rail when the clip (9) is in use.

摘要： In a method of manufacturing a rail clamp (13), for fastening a rail to an underlying rail plate or rail tie, the rail clamp is made from a blank formed of round bar stock which is pressed such that the blank has rounded edges. The method is applicable to the manufacture of a rail clamp of the type comprising a pair of substantially parallel members (14) folded into a D configuration so as to have a front portion adapted to seat on a flange of the rail, which front portion is formed by respective free ends of the substantially parallel members, and a base portion (12) adapted to seat in a slot in the rail plate or rail tie or in an anchoring device secured to the rail plate or rail tie.

摘要： A railway rail support assembly (3), for resiliently suspending a railway rail (1) above a track foundation (2) at discrete locations along the rail (1), has rail supporting means through which a predetermined clamping load is exerted on the said rail (1) such that the assembly (3) has a desired resistance to longitudinal creep therethrough of the rail (1). The rail supporting means are preferably attached, when the assembly (3) is in use, to an approximately horizontal upper surface of the said track foundation (2). Such an assembly (3) may be provided by first and second brackets (31, 32) and first and second elastic members (33, 34). Each of the said first and second brackets (31, 32) has a bearing part (312, 322) and a base part (311, 321), the bearing part (312, 322) being located adjacent to either sides of the rail (1) when the assembly (3) is in use and the base part (311, 321) being located on an upper surface of the said track foundation (2). The first elastic member (33) is located between the first bracket (31) and the rail (1) and the second elastic member (34) is located between the rail (1) and the second bracket (32), when the assembly (3) is in use. The assembly (3) further comprises means for maintaining the said predetermined clamping load.

摘要： A railway rail fastening clip (1) suitable for holding down a railway rail (2) is formed from a rod of resilient material bent so as to be approximately M-shaped in plan, the clip (1) being such that, when it is bearing on the flange of a rail (2), the longitudinal axis of a part (14) thereof, which interconnects inner legs (13, 15) of the M, lies in a reference plane which is substantially parallel, but not identical, to a plane containing the longitudinal axes of outer legs (11, 17) of the M. Such clips (1) are used with an anchoring device (5), which, as the clip (1) is installed therein, deflects the outer legs (11, 17) downwardly with respect to the inner legs (13, 15), so as to place the clip under stress.
