Abstract
A lubricator for the wheel flanges of railway vehicle wheels comprises an arm carrying a lubricating pad and a mounting element formed integrally with the arm. The mounting element fits into the entrance of the key slot in the brake beam head beside the brake retainer key. The key head fits in a groove in the top of the mounting element to retain the lubricator in place. When the lubricant is exhausted, the key is partially withdrawn to allow removal of the mounting element and the lubricator is replaced. When partially withdrawn, the key still retains the show on the brake beam head.
