Abstract
An applicator for mounting a block of solid lubricant to deposit a thin film of lubricant on the flange of a transit rail car wheel. The applicator (10) includes a bracket (12) adapted to mount the applicator to an unsprung portion of a transit rail car. A pivot arm (26) is pivotally connected at one end of bracket (12) and a block of solid lubricant (42) attached to a mounting plate (34) is bolted to the other end of the pivot arm. The block of solid lubricant is biased against the flange (40) of a transit car wheel by a torsion spring (28). A stop (32) prevents the pivot arm from contacting the wheel as the lubricant block wears by deposition of a thin film of lubricant on the rail car wheel flange as the wheel rolls.
