Abstract
A method and apparatus for applying a lubricant to an object is disclosed. The lubrication apparatus includes a rotatable and cylindrically shaped brush for applying the lubricant to the object, a housing for holding the brush, and a pump for applying the lubricant to the brush located in a chamber positioned below the brush. A vertical slide cylinder moves the brush in a generally vertical direction along the central axis in and out of the chamber, and a horizontal slide cylinder moves the brush in a generally horizontal direction transverse to the central axis to contact the object. The chamber has a sloped chamber cap connected to the top portion of the chamber for collecting lubricant that drips from the brush. The brush is preferably rotated by a motor. The method of applying the lubricant to the object includes the steps of applying the lubricant to the brush in the chamber, moving the brush to a vertical position equal that of the object, moving the brush horizontally to contact the object, and lubricating the object by rotating the object and the brush.
