A lubricating apparatus comprising a chamber to receive lubricant, an outlet for lubricant, a movable member to drive lubricant from the chamber through the outlet, and a control circuit for periodically activating the motor to dispense lubricant according to a preset schedule. A motor and drive shaft are attached to the movable member through a transmission. Activating the motor in accordance with operator-selected instructions from a pre-programmed micro-processor moves the transmission to drive the movable member towards the outlet to force lubricant therefrom. The apparatus avoids the disadvantage of the prior art which relies on the generation of gas to provide pressure to force lubricant from the apparatus.

1. A lubricating apparatus comprising:a housing defining a main lubricant chamber to receive a lubricant and having an outlet for lubricant; a central shaft disposed longitudinally within said chamber; a movable member tightly fitted within an inner surface of said main lubricant chamber, slidably mounted on said central shaft, and being movable towards said outlet to drive lubricant from the main chamber through said outlet by means of positive pressure on said lubricant by said movable member; a motor having a drive shaft; a fulcrum having opposite ends, and being attached at its proximal end to said housing; drive means comprising a system of levers attached to said fulcrum and said movable member, and being driven by said motor; electronic control means for controlling activation of said motor in accordance with a predetermined program.
