| 20100181386 | COMPONENTS FOR RAIL FASTENING ASSEMBLY - A component for use in a rail fastening assembly, the assembly comprising a railway rail fastening clip having a first part for bearing on a railway rail and a railway rail clip anchoring device for retaining the railway rail clip, comprises a first portion adapted to receive a lateral load from the rail when located between a substantially upright face of the rail clip anchoring device and the side of the foot of an adjacent railway rail when the assembly is in use. The component further comprises a second portion for receiving a second bearing part of the railway rail clip. The first portion and the second portion of the component are spaced apart and interconnected by a connection portion. | 07-22-2010 |
| 20090218410 | ANCHORING DEVICES FOR RAIL FASTENING CLIPS - A shoulder for use in retaining a railway rail fastening clip, comprising two interconnected spaced-apart walls, between which a portion of the clip to be retained is held when the shoulder is in use, and clip-engaging means, supported by the walls, for engaging a portion of the clip to be retained, does not have any feature or surface which engages the surface of that clip portion which faces downwardly when the clip is in use. Alternatively, or in addition, none of the contact regions, at which the device engages the rail clip, can be seen when the anchoring device is viewed from above when in its operative orientation and all of the contact regions can be seen when the anchoring device is viewed from below when in the operative orientation. Alternatively, or in addition, all the contact regions lie substantially at the same horizontal distance from the edge of the rail foot when measured perpendicularly to the axis of the rail and in the plane of the rail foot. | 09-03-2009 |
| 20090065599 | RAILWAY RAIL FASTENING CLIP - A substantially M-shaped rail clip is disclosed in which the clip is substantially flat when in its non-operative configuration, and, when the clip is in an operative configuration, the toe of the clip lies substantially in a second plane and the legs of the clip lie substantially in a third plane, the second and third planes being non-parallel to one another. | 03-12-2009 |
| 20090045265 | SEALING PLATE FOR RAILWAY RAIL CLIP ANCHORING DEVICE AND SLEEPER MANUFACTURING METHOD - A sealing plate for use with a rail clip anchoring device having a head and a stem which extends from the head into a concrete sleeper when the anchoring device is in use, is adapted for extending over the underside of the head when the stem of the device is being set in a concrete sleeper, thereby to prevent ingress of concrete into the head of the device, and for being retained on the surface of the sleeper thereafter. A major face of the plate, which is uppermost when the sleeper is in use, is provided with at least one clip seat portion for receiving part of a rail clip. In a method of manufacturing a concrete sleeper with at least one embedded rail clip anchoring device, the floor of a mould, from which the sleeper is to be formed, is provided with an aperture through which the head of an anchoring device is inserted and before concrete is introduced into the mould the aperture is sealed off around its edges and around the underside of the head of the anchoring device by placing a sealing plate over the aperture on the floor of the mould, the plate overlapping and sealing around the edges of the aperture other than where the anchoring device is located and having a mating interface with the anchoring device such that a seal is formed therewith. | 02-19-2009 |
