Publication number: 20190242067Abstract: An improved screwed fastening system for railway rails is proposed to allow rail fastening clips to be moved onto and off the rail more easily, facilitating track installation and maintenance. One improvement comprises providing in the screwed fastening system a clip guiding device, for guiding the rail fastening clip whilst it is being driven, which has an asymmetrically-located hole for receiving the screw-threaded shank of a screwbolt. Another improvement comprises providing in the screwed fastening system a rail fastening clip and screwbolt assembly which have inter-engaging driving portions. In each case, rotation of the screwbolt in one direction brings about translational movement of the rail bearing portion of the clip away from the screwbolt, and rotation of the screwbolt in the opposite direction brings about translational movement of the rail bearing portion of the clip towards the screwbolt.Type: ApplicationFiled: July 25, 2017Publication date: August 8, 2019Applicant: Pandrol LimitedInventors: Stephen John Cox, John David Spencer
