Abstract
An automatic lubricant dispenser has a vessel adapted to hold a supply of a fluent lubricant and having one side formed with an outlet adapted to be connected to a machine to be lubricated and an opposite side, a piston in the vessel movable forward toward the one side to force the lubricant from the outlet, and an electric drive connected to the piston and electrically energizable to advance the piston forward. An electric power source is connected via an electrical circuit to the drive for periodically energizing the drive and thereby advancing the piston an increment and pumping a dose of the lubricant from the outlet.
