Expansion joint on underlay for rail section - includes sliding tongue held against stock rail by clips

摘要

The tongue (34) slides along and against the head, web and foot of the stock rail (10,14,16) both of which are mounted on an underlay plate (20). On the underlay, on the opposite side of the rail to the tongue, is a rib tight against the foot (16) of the stock rail. A spring clip (46) straddles the rib and is bolted down to press on the foot of the rail. A profiled chair (38) mounted on the underlay is rebated (44) to take the foot (42) of the tongue, and recessed on its underside so as to contain the foot (16) of the stock rail. A spring clip (36) clamps down in the angle (35) formed by the foot and web (40,42) of the tongue. ADVANTAGE - Secure contact between the stock rail and the tongue, and neither can tilt. Efficient longitudinal movement of tongue on stock rail.
