ABSTRACT:
A compact, self-contained electrical lubricating device for lubricating a movable conveyor or other system while the conveyor or system is in operation. A tank for containing a reservoir of lubricating fluid includes a coverplate to which is mounted an electric pump having inlet ports immersed in the reservoir. Electrical circuitry including a triggered constant pulse width pulse generator is housed in a control module enclosure also mounted to the coverplate. A proximity switch mounted adjacent the conveyor or other system is actuated by the travel of the conveyor past the switch to trigger the pulse generator which enables the pump causing the pump to deliver a metered shot of lubricating fluid to the conveyor through feedlines extending from the pump through the coverplate. In another embodiment, the control module enclosure is mounted on a supporting base within a compartment separate from the lubricating fluid reservoir tank. A pump is mounted on a support platform within the reservoir tank.
