Liquid applying apparatus

Abstract

Apparatus for applying liquids including a main body and a carrier supporting the main body for movement, the main body having mounted therein conduits and charge-over valves for supplying liquids, and spray nozzles for spraying the liquids in predetermined amounts onto a liquid-absorptive, resilient contacting member to enable the latter to apply the liquids to a surface by sliding rubbing contact therewith as the carrier is actuated or for spraying the liquids directly onto the surface. The liquids absorbed by the contacting member are squeezed therefrom when a surface cleaning operation or a liquid applying operation is completed or any time the contacting member is soiled, by bringing the contacting member into pressing engagement with a liquid receiving pan. The contacting member may be in the form of a cylinder and mounted at a forward end of a hollow shaft rotatably connected to the carrier, so that the contacting member can be brought into rubbing sliding contact with the surface to apply the liquids thereto or can be covered with a movable cover to remove absorbed liquids by centrifugal forces. The conduits for supplying the liquids are connected to tanks containing the liquids and divided into a cleaning liquid feeding system and an applied liquid feeding system, and the change-over valves are capable of switching the apparatus between the two systems. The main body is capable of movement in a three dimensional space determined by the movement of various elements of the carrier in the directions of the X, Y and Z axes.
