ABSTRACT:
An oil reservoir gland stuffing box employed to extend the service life of the packing by providing an oil reservoir to maintain essential lubrication is provided with an attached container which will receive the overflow of the oil reservoir should the packing begin to leak excessively threatening thereby to create a pollution problem. A predetermined overflow actuates a weight sensitive micro-switch wired to shut off the pumping unit and/or send a warning signal to a remote control station. The control switch incorporates a manual re-set provision to prevent the pumping unit from restarting until the well has been serviced.
