Floor finish applicator
First Claim
1. A floor finish applicator comprising:
- frame means adapted for movement along a floor in any selected direction;
liquid finish storage tank means mounted on the frame means, said storage tank means having an inlet and an outlet and being adapted to hold liquid finish therein;
finish spreading means adapted to spread the finish out into a smooth, even finish after it has been applied to the floor, said finish spreading means being mounted in he applicator for transverse movement with respect to the frame as the frame moves in its selected direction in applying finish to the floor, said transverse movement being sufficient to permit the finish spreading means to follow a path along the floor that deviates from the path followed by the frame so as to permit the application of finish around obstacles and corners in a room as the frame is moved past such obstacles and corners; and
finish applying means for receiving liquid finish from the outlet of the storage tank and applying liquid finish to the floor in the path of the finish spreading means as the applicator is moved along the floor.

Abstract
A floor finish applicator comprises a frame mounted on wheels for movement in any selected direction, a liquid finish storage tank mounted on the frame, a finish applying mechanism adapted to deliver finish from the outlet of the storage tank to the floor, and a finish spreader adapted to spread the finish out into a smooth even finish after it has been applied to the floor. The finish spreader is mounted behind the frame and is movable in a transverse direction with respect to the direction of movement of the frame. The finish spreader is resiliently biased to remain in a predetermined position but is mechanically movable in either transverse direction. A roller is provided at one or both ends of the spreader in order to provide a rolling contact between the finish spreader and the wall of a room being finished. The applicator may be used to apply any type of liquid to a floor, including waxes, varnishes, cleaners or the like.

17. A floor finish applicator comprising:
-
frame means mounted on wheels and adapted to be rolled in any selected direction along a floor, said frame means having handle means for pulling the frame means manually; liquid finish storage tank means mounted on the frame means, said storage tank means comprising a closed pressurizable vessel having an inlet and outlet for liquid finish and an air pressure inlet, said storage tank means being adapted to hold liquid finish under pressure; air pressure tank means mounted on the tank and adapted to hold pressurized air; conduit means adapated to convey pressurized air from the air pressure tank means to the air pressure inlet of the storage tank means, said conduit means including valve means for regulating the air pressure in the storage tank means; an elongated spreader frame positioned adjacent the floor behind the frame means, said spreader frame extending transversely with respect to the frame means; a mop mounted on the underside of the spreader frame so as to be in contact with the floor; spray nozzle means mounted on the spreader frame and adapted to spray liquid finish on the floor in front of the spreader frame in a predetermined manner, said nozzle means including check valve means adapted to prevent finish from dripping from the nozzle means after the applicator has been shut off; conduit means adapted to convey liquid finish from the outlet of the storage tank means to the spray nozzle means, said conduit means including shut off valve means for controlling the spraying of liquid finish on the floor; control means mounted on the frame means for selectively actuating the shut-off valve means so as to spray liquid finish on the floor; mechanical linkage means pivotally connecting the spreader frame to the frame means for pivotal movement of the spreader frame about a vertical axis, said mechanical linkage means including linkage means adapted to hold the spreader frame in transverse alignment with the frame means as the spreader frame is moved pivotally with respect to the frame means; manually operable lever arm means connected to the mechanical linkage for manually pivoting the spreader frame in either a clockwise or counterclockwise direction; resilient biasing means adapted to urge the spreader frame in a one pivoted direction so that one end of the spreader frame is urged in a transverse direction away from the frame means; and a roller mounted on said one end of the spreader frame for rotation about a vertical axis, the roller being mounted such that the longitudinal position of the roller with respect to the end of the spreader frame is adjustable.
