ABSTRACT:
An air line lubricator with safety device for automatically actuating an air actuatable member located outside of the lubricator. The air actuatable member may be a valve which controls a tool, or a signal which indicates that the oil level in the lubricator bowl has fallen below a predetermined level. The lubricator bowl contains oil and pressurized air and an air tube which receives pressurized air from the bowl when the oil level is below a predetermined level. The air tube has a relatively small intake end opening and a relatively wider internal diameter. An oil level controlled member may be a float or a float controlled piston which is movable relatively to said tube opening and is supported by the oil when the oil level is above a predetermined level. The face of the oil level controlled member has mounted thereon a tiltable member for engagement by the air tube open end. A vibration coating is applied to said tiltable member to maintain its sealing engagement with the air tube open end when the oil is above said predetermined level.
