摘要： An improved screwed fastening system for railway rails is proposed to allow rail fastening clips 2, 2000 to be moved onto and off the rail 4 more easily, facilitating track installation and maintenance. One improvement comprises providing in the screwed fastening system a clip guiding device 1000, for guiding the rail fastening clip 2 whilst it is being driven, which has an asymmetrically-located hole 1016 for receiving the screw-threaded shank of a screwbolt 3. Another improvement comprises providing in the screwed fastening system a rail fastening clip 2000 and screwbolt assembly 3000 which have inter-engaging driving portions 2201, 3305. In each case, rotation of the screwbolt 3, 3050 in one direction brings about translational movement of the rail bearing portion 23, 2300 of the clip 2, 2000 away from the screwbolt 3, 3050, and rotation of the screwbolt 3, 3050 in the opposite direction brings about translational movement of the rail bearing portion 23, 2300 of the clip 2, 2000 towards the screwbolt 3, 3050.

摘要： A rail fastening apparatus for fastening an inner stock rail (2) in a railway slide chair assembly comprises a baseplate (100) having on one face thereof a rail seat region (110) on which the inner stock rail (2) sits when the slide chair assembly is in use, a resilient rail fastening clip (7) for restraining such an inner stock rail (2), the clip (7) comprising an elongate member having at one end a toe portion (71) for bearing on the rail (2) and at its other end a heel portion (72), first locating means (101) for locating the rail fastening clip (7) in the apparatus in a first position, which means (101) comprise a first abutment surface (101a), positioned on the baseplate (100) in a second region (120) spaced from the rail seat region (110), against which surface the heel portion (72) of the clip (7) abuts when the apparatus is in use to inhibit withdrawal of the clip (7) from the rail (2), and loading means (9) for vertically deflecting the clip (7) so as to produce a load in the toe portion (71). The loading means (9) comprise a ramp (9) provided adjacent to the rail seat region (110), whereby the clip (7) can be installed in the apparatus by hammer-driving the heel portion (72) of 25 the clip (7) towards the rail seat region (110) until the toe portion (71) slides up the ramp (9) onto the rail (2) and the heel portion (72) comes into contact with the first abutment surface (101a). Second locating means (102) are provided for locating the rail fastening clip (7) in the apparatus in a second position, different from the first, into which the clip can be driven such that the toe portion of the clip sits on the ramp (9) in a pre-load condition in which the clip does not bear on the rail.
