The lubricator system comprises a pump, a lubricant reservoir, and distribution pipework which includes branch pipes (18) extending along each sleeper (3), with nozzles (21) located at the ends of the branch pipes (18) adjacent the slide surfaces (10) of the chairs (11) which are mounted on the sleeper (3) for supporting the fixed (2) and movable (6) switch rails. Each nozzle (21) is positioned at or below the level of the slide surface (10) and is adapted to project lubricant in an initially upward trajectory and so as to land on the chair slide surface (10); in such positions the nozzles (21) are located very close to the slide surfaces (10) to be lubricated yet out of the way of the movable rail (6) and other railway equipment such as switch heaters. Each nozzle (21) may be of a type which produces a flat spay pattern. The distribution pipework may include a longitudinal feed pipe of rigid telecopic pipe sections which adjustably bridge the spacings between the sleepers. |
