  • Patent number: 4469278
    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. A generally U-shaped locking pin clamps the rail clip to the shoulder and biases the clip tip toward the rail assembly to create the desired hold down pressure. This configuration is particularly adapted for use in holding down railway rail assemblies in the vicinity of joints where hold down clearance is minimal. 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.

  • Patent number: 4448349
    Abstract: There is disclosed a rail sleeper which when secured to rails affords rapid disengagement when necessary and is comprised of a metal bar of a U-shaped channel section. At two locations along the length of the bar portions of flanges of the sleeper are removed to provide slots disposed at right angles to the longitudinal axis of the bar. Each slot is wider than the base of the rail fitting thereinto with the space between slots dependent upon the gage between parallel rails and with the depth of such slots being varied to suit rail height. One rail flange is secured in place by an overhanging portion of the sleeper flanges. The other rail flange is secured by a generally T-shaped steel plate which is bolted to the bottom of the U-shaped channel section such that the horizontal bar of the T-shaped plate rests across the upright flanges of the sleeper. One edge of the horizontal bar engages the web of the rail and the other edge engages the edge of the slot, thus wedging the rail into secure engagement.

  • Patent number: 4424935
    Abstract: A resilient rail fastener having a clip having a lower leg with a toe at one end and a heel at the other, an upstanding back portion between the heel and an upper leg, and a rectangular locating aperture in at least one of its legs which engages over a rectangular retaining block. The retaining block has pressure imparting means projecting from each side and bearing downwardly on the upper leg of the clip and thereby applies a downward pressure at each end of the lower leg. One end of the lower leg bears downwardly on the rail support and the other end on the rail to impart a toe pressure. The reduced cross-sectional area of the clip where it passes over the retaining block causes high stresses in the legs of the clip as well as at the locality of the clip heel, and the upstanding back portion has less stress than a hairpin clip, and this results in a lower spring rate for the toe clip so that toe pressure is retained upon rail settlement, and stress corrosion is reduced.
