Abstract

Abstract A brush for application of paint or the like is formed of a handle and an applicator envelope. The applicator envelope is an integral piece without bristles formed of soft spongy material. It is connected to a holding extension which is capable of sliding into the handle by a clamping arrangement, such as inwardly bent lateral extensions of a clamping device secured to the holding member which engage the applicator envelope and are clamped against it by the insertion of the holding member into a pocket in the handle.

Claim 1
Independent Claim 204 words
Brush for laying on of paints, varnish, lacquer or the like, which comprises a hollow handle part of substantially greater width than thickness having a downward opening therein and an applicator part including a yieldable porous sponge-like material which receives the coating material on the working surface in the form of a thin film, the applicator part further including a member insertable in the opening with a cross-piece and a downwardly projecting extension thereon extending across the greater part of the width and rigid in the directioN of its width, said extension being enclosed within the yieldable material, clamping means for releasably holding the applicator part in the handle part, said clamping means comprising clamping jaws extending widthwise of and hinged along the longer sides of the cross-piece for movement between outwardly projecting and downwardly bent positions, said clamping jaws in released condition being spread apart and by insertion of the clamping means in the handle being positioned and clamped between the yieldable material and the inner wall of the handle part, whereby the yieldable material is held in the handle part and against the extension, the clamping jaws being hinged to the cross-piece intermediate their width, thereby extending above and below the cross-piece.
