The Hey-Back rail fastening has two components. One is a rolled-steel base plate with parallel ribs on each side of the rail seat to hold the rails to gauge. The outer side of each rib is curved over in such a manner as to form a keyway, into which there is driven a spring steel clip. The lower side of each clip is tapered from both ends at a leading angle to facilitate its entry into the keyway; as the clip is driven in, the taper forces the clip forward, with its double bend acting as a fulcrum in the keyway, until the opposite side is exerting considerable pressure on the rail-foot. To ensure perfect contact between key and keyway, each keyway is machined to a fine tolerance. The baseplate is held down to the sleeper by coachscrews, chair-bolts, or other fastenings of a normal type. Additional information is given relating to advantages and use with timber and concrete sleepers.
