ABSTRACT:
An apparatus is provided for continuously cleaning rust and other corrosion from elevator guide rails and for filling pits, joints and other irregular areas in the rails. A plurality of guide brackets are mounted on the car for contact with the rail. Each guide bracket includes a bushing insert for contact with surfaces of the guide rail. In one embodiment, the insert is made from an elastomeric material with particles of bronze or brass embedded therein. In a second embodiment, the insert has lead embedded therein. Where the insert has bronze or brass embedded therein, the sliding of the insert relative to the walls of the guide rails acts as an abrasive cleaner to remove rust, corrosion and dirt particles from the surface of the rails. Where the insert has lead embedded therein, contact between the insert and the rail results in the transfer of lead to the rails to fill pits, joint areas and irregularities in the rails. The inserts are formed with a plurality of ribs in which some are inclined upwardly while others are inclined downwardly from the longitudinal axis of the rail. Corrosion and rust scoured from the rail are channeled by the ribs and intermediate troughs away from the operating surface of the rails. Brush units are attached to the elevator car on opposite sides of each rail for contact with the rails. A cleaning solution is supplied to the brush units to provide further cleaning of the rails during operation of the elevator.
