Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
297 words
In a floor finish applicator wherein liquid finish is applied to a floor and spread out into a smooth even finish by moving over the floor surface a finish spreading means having a soft, absorbent floor contacting material on the underside thereof, an improved means for applying and spreading finish on the floor comprising: porous floor contacting mop means for simultaneously applying and spreading liquid finish on the floor, the mop means comprising a floor contacting mop material formed of a plurality of fibrous strands attached to a fabric backing and being fabricated such that liquid finish applied to the top of the fabric backing of the mop means flows through the fabric backing and soaks into the mop material and is dispensed on the floor by contact between the soaked mop material and the floor, the fabric backing of the mop means being sufficiently porous to permit enough liquid finish to flow through the mop means solely under the influence of gravity to provide an adequate but not excessive covering of liquid finish for the floor as the mop means is moved over the floor said mop means providing a smooth and even distribution of liquid finish over the floor as said mop is moved over the floor; spreader frame means for supporting the mop means on the underside thereof in floor contacting position as it is moved across the floor; and finish dispensing means for continuously dispensing liquid finish on the upper side of the fabric backing of the mop means as the mop means is moved across the floor, the finishing dispensing means applying no pressure on the liquid finish to force it through the mop means but permitting the liquid finish to flow through the mop means solely under the influence of gravity.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
65 words
A floor finish applicator as claimed in claim 1 wherein the spreader frame means includes openings therein that permit liquid finish to pass downwardly into the mop means from the top of the spreader frame means, said finish dispensing means dispensing liquid finish on the top of the spreader frame means, the liquid finish passing through the spreader frame means and into the mop means.
Claim 4
Dependent Claim
69 words
A floor finish applicator as claimed in claim 2 wherein the spreader frame means includes a receptacle for liquid finish extending over the top of the mop means with the receptacle being perforated to permit liquid finish to drip downwardly into the mop means, the finish dispensing means dispensing liquid finish to the receptacle by means of a hollow perforated outlet tube extending along the receptacle and mounted thereabove.
Claim 5
Dependent Claim
72 words
A floor finish applicator as claimed in claim 3 wherein: the perforations in the receptacle are formed adjacent the forward edge of the tray and the receptacle is sloped downwardly toward said perforations so as to urge liquid finish to flow to said perforations; and the mop means is perforated to provide sufficient porosity for application of liquid finish on the floor through the mop means solely under the influence of gravity.
Claim 6
Dependent Claim
17 words
A floor finish applicator according to claim 1 wherein the mop means is a perforated cotton mop.
Claim 7
Dependent Claim
17 words
A floor finish applicator according to claim 1 wherein the mop means is a perforated nylon mop.
Claim 8
Dependent Claim
17 words
A floor finish applicator according to claim 1 wherein the mop means is a perforated rayon mop.
