Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
252 words
A surface coating applicator comprising: a tubular ferrule having a cluster of bristles inserted partway into one end, substantially to seal one end of said ferrule; a hardened mass of cured, resinous cement disposed atop said cluster of bristles in firm adhesive connection with portions of said cluster of bristles in said ferrule, and an integral handle including a gripping portion extending outwardly from the other end of said ferrule; said handle being of ridged material and having a series of vertically aligned openings that extend through said handle such that a rod may be inserted completely through a selected opening; said openings are located at specific distances from the one end of the ferrule into which the bristle cluster is inserted, such that said rod can be used to support one or more applicators of the same or differing length and/or size in a container of solvent, such that the level of solvent only covers the clusters of bristles of each applicator up to the said end of said ferrule for proper soaking and cleaning of all clusters of bristles; said cluster of bristles being made of two bristle sub groups being distinctly different in bristle length and bristle color; said first bristle subgroup being longer and used for applying the surface coatings; said second bristle subgroup being significantly shorter and of a contrasting color to the first bristle subgroup, so as to reduce the possibility of a painter dipping the surface coatings applicator too deeply into the coatings supply container.
