Abstract
Abstract A compact, self-contained lubricating device for lubricating a movable conveyor or other system while the conveyor or system is in operation. In a first embodiment, a tank enclosure for containing a reservoir of lubricating fluid includes a coverplate to which is mounted a pneumatically operable pump having an inlet immersed in the reservoir, a manifold with several air and lubricating fluid passageways, an air pressure regulator and a quick air exhaust valve. An air valve trip device is mounted for actuation by the conveyor system and pneumatically coupled to the pump through the manifold to deliver clean shots of lubricating fluid to the conveyor or system. In a second embodiment, a lubricating fluid reservoir is mounted above a control module enclosure. The control module enclosure contains a pump, fluid manifold and fluid interconnecting lines to seal these components from any possible destructive environment. A flexible tube communicates the reservoir outlet to the pump inlet, and a pair of side inspection plates on the control module enclosure permit inspection and access to the module interior.
