Abstract: The invention describes a clamp for rails that is produced from resilient steel bar with multiple bends. The first section (11) of the rail clamp (9, 10) is essentially horizontally arranged, while the last section (14) rests on the rail flange (5). The second section (12) curves upwards in the vertical plane that passes through the first section (11). The remaining sections of the clamp lie all on the side of the first section that faces the rail. The fastening arrangement comprises an anchoring part (20) where the supporting surface (23) for a supporting section of the clamp (9, 10) is located essentially vertically above the locating hole (24) of the clamp (9, 10). That produces a relatively short clamp requiring a minimum of material.

Abstract: A novel hold down apparatus for holding railway rail assemblies to concrete ties fitted with Pandrol-type shoulders is disclosed. The apparatus generally comprises a rail clip seated on the upper surface of the Pandrol-like shoulder. The tip of this clip engages a portion of the rail assembly.

The disclosed apparatus also facilitates the use of novel, high resiliency rail pads. The disclosed fastening system is intended to extend the useful life of concrete ties which are now subject to severe cracking due to existing high impact couplings between the rail and concrete ties.

Abstract: A railroad rail is secured to a support normally constituted by a rail-fastening plate by means of a bolt engaged in this plate and a clip pressed by the bolt downwardly on one side against the plate and on the other side against the flange of the rail. To this end the clip is unitarily formed from a single piece of steel wire with a support leg that rests on the support and has one end connected via a bight extending over a ridge on the support to a bearing leg that bears on the flange of the rail. The other end of the support leg is extended to form an eye through which the bolt passes and the wire forming this clip has a bent-down end at the eye that limits the tightening of the bolt by abutment with the top of the ridge. Thus the support leg is twisted about its straight axis when the fastener is tightened for torsional loading.
