Patent number: 11753774Abstract: An anchoring device for use in retaining a railway rail fastening clip having first and second leg portions and a rail-bearing portion therebetween. The anchoring device includes a base member, an opening in the base member configured to receive a fastening component for fastening the anchoring device to an underlying foundation, and first and second clip-retaining sides extending from said base member with the first clip-retaining side being spaced apart from the second clip-retaining side so as to define a space therebetween for receiving the rail-bearing portion of the clip. Each clip-retaining side comprising upper and lower clip contact walls defining a passageway for receiving one of the leg portions, wherein the leg portions contact the clip contact walls of the respective clip-retaining sides as the clip moves from a wedged position towards an engaged position where the rail-bearing portion of the clip bears on the rail.Type: GrantFiled: February 28, 2019Date of Patent: September 12, 2023Assignee: Pandrol LimitedInventors: John Phillip Porrill, John David Spencer, Stephen John Cox, Brenton Keast, Steven Harkness, Chris Lea

Patent number: 7954727Abstract: 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.Type: GrantFiled: February 21, 2007Date of Patent: June 7, 2011Assignee: Pandrol LimitedInventors: Stephen John Cox, John Phillip Porrill, Robert John Hamilton, Jozef Nevidal, Martin Somerset, Paul Hewlett, Christopher Gardner

Patent number: 7874527Abstract: A rail fastening apparatus fastens an inner stock rail in a railway slide chair assembly. The apparatus includes a base plate. The base plate has on one face a rail seat region on which the inner stock rail sits when the slide chair assembly is in use. A resilient rail fastening clip restrains the inner stock rail. A locating means locates the rail fastening clip in a first position. A loading means vertically deflects the clip so as to produce a load in a toe portion of the clip.Type: GrantFiled: June 10, 2005Date of Patent: January 25, 2011Assignees: Pandrol Limited, VAE Eisenbahnsysteme GmbH, VAE GmbH, BWG GmbH & Co.
