Title: Open-topped pan collecting lubricant from railway points - has oil-retaining fibrous insert and water discharge siphon
Inventor: SITTINGER RUDOLF
IPC: E01B7/26
Filed: 1989-10-25
Abstract: Lubricant applied to the points in railway track systems is detached as the points are operated, or by impinging rain or melting snow or ice. To orevent this oil sintering into the grout, it is collected in a flat pan, e.g., made of galvanised steel, inserted below the points and in contact with the rail and the points slide chair. Oil is taken up into an insert, pref. of U-shape, surrounding the points and consisting of inert non-woven polypropylene fibres, combining hydrophobic and oleophilic properties. When set with oil, the insert can be removed during maintenance. A small syphon tube projecting from the pan end discharges the water content from the pan interior. ADVANTAGE - Reduces discharge of oil into ballast and then submerged waters, with beneficial long-term environmental effect.
