Abstract
Abstract A tool for applying a liquid stain to a flat surface to impart a timber grain effect comprising a paint brush, a bristle retaining slidable plate on one side of the brush and a slidable comb plate on the other side of the brush. Both the plates have an elongated slot which engages a bolt which passes through the paint brush. The comb adjustably separates the brush bristles into discrete bunches to permit the application of stain to impart a wood grain pattern.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
A graining tool comprising, in combination, a paint brush, a bristle-retaining slidable plate having an elongated slot therein and a finger rest and pull-back lever thereon, a slidable comb plate terminating in a comb and having a second elongated slot therein together with a finger grip, said comb plate being adapted to slide within said bristle-retaining plate via fittingly co-acting respective margins of said plates, the latter being adapted to encompass the bristles of said brush in registering juxtaposition therewith, and lockably removable fastening means being adapted to engage said slots via a preformed hole in the bristle-supporting base of said brush, whereby said comb adjustably separates said brush bristles into discrete bunches to an extent determined by the relative endwise adjustment of said plates responsive to relative displacement of said finger grip with respect to said finger rest and pull-back lever, thereby permitting the application of said brush to a pre-stained surface to cause said bunches to impart a wood grain simulating pattern to said surface as said brush is manipulated across said surface with a pattern-describing motion.
Claim 2
Dependent Claim
179 words
A graining tool comprising, in combination, a paint brush, a bristle-retaining slidable plate having an elongated slot therein and a finger rest and pull-back lever thereon, a slidable comb plate terminating in a comb and having a second elongated slot therein together with a finger grip, said comb plate being adapted to slide within said bristle-retaining plate via fittingly co-acting respective margins of said plates, the latter being adapted to encompass the bristles of said brush in registering juxtaposition therewith, and lockably removable fastening means being adapted to engage said slots via a preformed hole in the bristle-supporting base of said brush, whereby said comb adjustably separates said brush bristles into discrete bunches to an extent determined by the relative endwise adjustment of said plates responsive to relative displacement of said finger grip with respect to said finger rest and pull-back lever, thereby permitting the application of said brush to a pre-stained surface to cause said bunches to impart a wood grain simulating pattern to said surface as said brush is manipulated across said surface with a pattern-describing motion.
Claim 3
Dependent Claim
73 words
A graining tool as claimed in claim 1, wherein said fastening means comprises a threaded bolt and a wing-nut applicable thereto, the head of said bolt being co-extensive with a detent adapted to engage the slot in said slidable plate to prevent the rotation of said head with respect to said slot when said wing-nut is tightened with respect to said bolt to thereby clamp said plates about the bristles of said brush.
Claim 4
Dependent Claim
41 words
A graining tool as claimed in claim 2, wherein said bolt is slidable along said slots longitudinally upon slackening said wing-nut, to thereby permit relative displacement of said plates to vary the degree of bunching of said bristles by said comb.
Claim 5
Dependent Claim
27 words
A graining tool as claimed in claim 2 or claim 3, wherein said fastening means is removable entirely from said slots to permit dismantling of said tool.
Claim 6
Dependent Claim
37 words
A graining tool as claimed in any one of claims 1-3, wherein said slidable comb plate is one of a series of such plates each possessing a terminating comb thereon having a different number of comb teeth.
Claim 7
Dependent Claim
18 words
A graining tool as claimed in any one of claims 1-3, wherein said brush is a bat brush.
Claim 8
Dependent Claim
19 words
A graining tool as claimed in any one of claims 1-3, wherein said plates are fabricated from sheet metal.
