Buffing pad washer for use with multiple types of power drivers

An apparatus for cleaning a rotary, dual action or random orbital power driven buffing pad having a buffing face, while the pad is mounted on an operating buffing machine, the apparatus comprising:

• a reservoir for a liquid cleaning solution including an outer wall having a peripheral upper edge defining an open upper end;
• a base plate supported on the upper edge of the reservoir and having an outer wall, the wall including an annular shoulder defining a radially outer upper support surface and a central recess defining a lower support surface;
• a foraminous wash plate supported over the base plate, the wash plate having a circular outer edge portion spaced vertically above the upper support surface in a rest position;
• the wash plate connected to the base plate with a biasing arrangement positioned between the underside of the wash plate and the lower support surface, the biasing arrangement operative to hold the wash plate in the rest position and to permit vertical downward movement of the wash plate to a stop position in contact with the upper support surface in response to manual downward operator movement of the pad face against the wash plate;
• and,
• a pump having an inlet for cleaning solution in the reservoir and an outlet in liquid a closed path providing pressurized communication with a chamber on the underside of the wash plate, the pump having a spring-biased pumping plunger operable in response to biased vertical reciprocal movement of the wash plate to deliver pressurized cleaning solution to the chamber, through the foraminous wash plate and against the face of the pad.

An apparatus for cleaning a rotary, dual action or random orbital power driven buffing pad while the pad is mounted on an operating huffing machine, the apparatus supported on the rim of and extending downwardly into an open-ended reservoir containing a liquid cleaning solution, the apparatus comprising:

• a base plate supported on the rim of the reservoir, the base plate having a cylindrical outer wall and a lower enclosing support surface;
• a foraminous wash plate supported over the base plate support surface with a biasing arrangement positioned between an underside of the wash plate and the support surface, the biasing arrangement operative to hold the wash plate in a rest position and to permit vertical downward movement of the wash plate relative to the base plate to a stop position in response to manual downward operator movement of the pad face against the wash plate;
• and,
• a pump having an inlet for cleaning solution in the reservoir and an outlet in liquid communication with the underside of the wash plate, the pump having a spring-biased pumping plunger operable in response to biased vertical reciprocal movement of the wash plate to deliver pressurized cleaning solution to a chamber in the underside of the wash plate, through the foraminous wash plate and against the face of the pad.
