Abstract A device for cleaning the bristles of a brush and for pointing the bristles includes a reservoir for a cleaning liquid for the bristles. A top for the reservoir includes a guide aperture through which the brush can be inserted to enable the bristles to be inserted into the liquid in the reservoir. A point forming aperture for the bristles communicates with the guide aperture. The point forming aperture includes a pair of resilient, normally contacting lips that are formed as a slit in a sponge. The lips are urged apart as the brush is withdrawn from the reservoir and surround and contact the bristles to control the shape of the bristles. The sponge includes a foot that is inserted into the liquid to draw the liquid by capillary action to the lips so that they are maintained moist. To form a fine tip on the brush, the brush is rotated about its longitudinal axis while the bristles are drawn through the lips. To provide a chisel tip, the brush is drawn through the lips without turning it about its longitudinal axis.

Total Claims: 7
Claim 1
Independent Claim
153 words
A device for cleaning bristles of a brush and for pointing the bristles comprising means forming a reservoir for a liquid adapted to clean the bristles, a top for said reservoir, said top including: (a) a guide aperture through which the brush bristles can be inserted to enable the bristles to be inserted into the liquid, and (b) a point forming aperture communicating with the guide aperture to receive the brush from the guide aperture, said point forming aperture having a pair of resilient normally contacting lips that are urged apart in a region in contact with the brush but which surround and contact the moist bristles to control the shape of the bristles as the bristles are drawn through the forming aperture from the reservoir, further including drawing means for moistening the lips with liquid from the reservoir, wherein the drawing means includes capillary means extending from the reservoir to the lips.
Claim 2
Independent Claim
153 words
A device for cleaning bristles of a brush and for pointing the bristles comprising means forming a reservoir for a liquid adapted to clean the bristles, a top for said reservoir, said top including: (a) a guide aperture through which the brush bristles can be inserted to enable the bristles to be inserted into the liquid, and (b) a point forming aperture communicating with the guide aperture to receive the brush from the guide aperture, said point forming aperture having a pair of resilient normally contacting lips that are urged apart in a region in contact with the brush but which surround and contact the moist bristles to control the shape of the bristles as the bristles are drawn through the forming aperture from the reservoir, further including drawing means for moistening the lips with liquid from the reservoir, wherein the drawing means includes capillary means extending from the reservoir to the lips.
Claim 3
Dependent Claim
43 words
The device of claim 1 wherein the lips are formed by a sponge like material extending into said liquid reservoir, said capillary means including a foot of said sponge like material adapted to draw liquid from said reservoir to maintain the lips moist.
Claim 4
Dependent Claim
30 words
The device of claim 2 wherein the sponge like material includes a slit forming the lips and a pair of edges tapering outwardly from the slit to the guide aperture.
Claim 5
Dependent Claim
16 words
The device of claim 3 wherein the top forms a removable cover for said reservoir means.
Claim 6
Dependent Claim
49 words
The device of claim 4 wherein the cover includes a further aperture for receiving a mass of the sponge like material, said mass having an area in excess of said further aperture and a slot for receiving the cover so that the mass is captured in said further aperture.
Claim 7
Dependent Claim
15 words
The device of claim 1 wherein the lips are formed by a sponge like material.
