Liquid applying apparatus

A liquid applying apparatus comprising:

• a main body;
• a carrier supporting said main body for movement;
• liquid applying means mounted on said main body and comprising a surface rubbing means including a liquid-absorptive, resilient contacting member and a supporting member supporting said contacting member, and a spray nozzle means for selectively applying a variety of liquids to a surface of a structure;
• liquid feeding means comprising conduit means and valve means for supplying said variety of liquids in predetermined amounts to said liquid applying means;
• and
• liquid removing means mounted in said main body for removing liquids from said liquid applying means to clean the same, said liquid removing means comprises a liquid receiving pan adapted to be brought into pressing engagement with said contacting member for squeezing liquids from said contacting member;
• said liquid applying means receiving a supply of liquids through said liquid feeding means for cleaning the surface of the structure and applying desired liquids thereto by rubbing the surface by said contacting member as said carrier is actuated, and said liquid removing means being effective to remove liquids from said liquid applying means by performing a liquid removing operation selectively wih a surface cleaning operation and a liquid applying operation performed by said liquid applying means, whereby application of the liquids can be effected automatically with a high degree of efficiency and without any loss of the liquids.

• a carrier supporting said main body for movement;
• a liquid applying means mounted on said main body and comprising a surface rubbing means including a liquid-absorptive, resilient contacting member and a supporting member supporting said contacting member, and a spray nozzle means for selectively applying a variety of liquids to a surface of a structure, said liquid-absorptive, resilient contacting member is cylindrical in form and said liquid applying means further comprises a hollow, cylindrical shaft connected for rotation to said carrier and detachably supporting said cylindrical contacting member at its forward end through said supporting member which is in the form of an attachment formed with a multitude of apertures in its wall;
• liquid feeding means comprising conduit means and valve means for supplying said variety of liquids in predetermined amounts to said liquid applying means;
• said conduit means of said liquid feeding means includes a fixed conduit extending through said hollow cylindrical shaft to selectively supply liquids to said cylindrical contacting member through said apertures in said attachment;
• liquid removing means mounted in said main body for removing liquids from said liquid applying means to clean the same, said liquid removing means comprises a movable cover movable to a position in which said cylindrical shaft is rotated at high speed to remove liquids from said cylindrical contacting member by centrifugal forces so as to avoid scattering of the removed liquid;
• said liquid applying means receiving a supply of liquids through said liquid feeding means for cleaning the surface of the structure and applying desired liquids thereto by rubbing the surface by said contacting member as said carrier is actuated, and said liquid removing means being effective to remove liquids from said liquid applying means by performing a liquid removing operation selectively with a surface cleaning operation and a liquid applying operation performed by said liquid applying means, whereby application of the liquids can be effected automatically with a high degree of efficiency and without any loss of the liquids.

A liquid applying apparatus comprising:

• a main body;
• a carrier supporting said main body for movement, said carrier is movable in such a manner that said main body is capable of movement in a three dimensional space determined by the movement of various elements of said carrier in directions of an X-axis, Y-axis, and Z-axis;
• liquid applying means mounted in said main body and comprising a surface rubbing means including a liquid-absorptive, resilient contacting member and a supporting member supporting said contacting member and a spray nozzle means for selectively applying a variety of liquids to the surface of a structure;
• liquid feeding means comprising conduit means and valve means for supplying said variety of liquids in predetermined amounts to said liquid applying means;
