Abstract
An apparatus for painting a surface, having an absorbent paint applicator containing paint and contacting the surface; a tube filled with paint and connected to the applicator; and a metering device for incrementally metering paint onto the applicator from the tube. The metering device has a plunger reciprocating within the tube, with the plunger having a handle. The plunger can either be incrementally advanced within the tube by rotating the handle, thereby incrementally dispensing paint onto the applicator, or the plunger can be manually retracted within the tube to fill the tube with paint and manually advanced within the tube to dispense the paint. The plunger is helically grooved along its length and a converter translates rotation of the handle into linear motion of the plunger, thereby advancing the plunger within the tube.
