Abstract: The present invention provides an isolator particularly adapted for use with a rail anchor utilized in an application where railroad rail is installed on concrete ties. The isolator protects the concrete tie from contact with the rail anchor caused by longitudinal movement of the rail due to train acceleration of deceleration or expansion and contraction due to temperature changes. In one embodiment, the isolator is comprised of a structural plastic material and includes a front face section and a rear face section. The front face section and rear face section each comprise a generally rectangular structure, having a top edge, bottom edge, and side edges. Top and bottom sections join the front face section and rear face section and form part of the isolator. The rail anchor also comprises a support section that extends from an intersection of the rear face section with the bottom section. The rail isolator is designed to be embedded in a concrete railroad tie.

Abstract: A rail fastening clip is used with a rail clip support having a rail clip slot of the kind used in K plates. The rail clip is formed from a U shaped member made of metal plate having a base and two arms tapered from the base to their tips, with the arms being bent inwardly beyond the base in a large arc and the tips are bent back toward the base and oriented for contact with the foot of the rail. The base is adapted to fit in the K plate slot of the rail clip support. The base of the clip has a leading edge remote from the arms that contacts the upper interior surface of the support slot to form at least a line of contact with the upper interior surface of the slot. The line of contact is about 6 mm. The design overcomes the problem of rotation of the clip within the support slot and is a more cost effective clip than that currently used with K plates.

Abstract: This invention relates to rail anchorages that are used with all rails, but is particularly concerned with adjustable rail anchorages, which allow rail alignment to be adjusted, and which are installed on rails used by cranes. To reduce this rail movement and to help limit vertical uplift of the rail, pressure is applied to the rail flange by resilient material attached to the part of the rail anchorage that overhangs the rail flange. The object of this invention is to provide support to the resilient material in a way that its length can be increased from the bonded surface or outside of the pocket in which it is installed. The invention allows for a greater variation in rail size and rail elevation that can be accommodated with one rail anchorage type and differing lengths of the resilient material. Please refer to FIG. 12 in the accompanying drawings.
