MOTOR DRIVEN LUBRICATOR

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.
