Abstract
Abstract The invention contemplates a brush in which a bundle of natural brush bristles is secured to a tubular retaining ferrule having a bore open at both ends. The root ends of the bristles are assembled within the bore, with the tip ends projecting outwardly as the applicator end of the brush. A guided pin is inserted on the central axis of the bundle to radially outwardly further compact the bristles in the bore, and to serve a molding function as a thermosetting resin is cured to hardness; the root ends are thereby bonded to each other and to the ferrule, and a smooth central passage is defined for pomade supply.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
127 words
As an article of manufacture, a brush comprising an elongated tubular ferrule with a radially compressed packed bundle of bristles in part contained by said ferrule and in part projecting beyond one end of said ferrule, all said bristles being continuously elongated in substantial overlap with each other at least within the ferrule, the portion of said bristles within said ferrule including the base ends of said bristles, and a hardened bonding material radially permeating said bundle near the base ends and bonding said bristles to each other and into an effectively solid end secured to said ferrule, the bonding material and adjacent central continuous bristles defining a smooth continuously walled central passage for liquid, said passage extending at least for the length of the bonded region.
Claim 2
Dependent Claim
127 words
As an article of manufacture, a brush comprising an elongated tubular ferrule with a radially compressed packed bundle of bristles in part contained by said ferrule and in part projecting beyond one end of said ferrule, all said bristles being continuously elongated in substantial overlap with each other at least within the ferrule, the portion of said bristles within said ferrule including the base ends of said bristles, and a hardened bonding material radially permeating said bundle near the base ends and bonding said bristles to each other and into an effectively solid end secured to said ferrule, the bonding material and adjacent central continuous bristles defining a smooth continuously walled central passage for liquid, said passage extending at least for the length of the bonded region.
Claim 3
Dependent Claim
157 words
As an article of manufacture, a brush comprising an elongated tubular ferrule having a bore open at an inlet liquid-receiving end of larger cross-sectional area than the opposite outlet end, there being a tapered portion of the bore connecting said larger and smaller areas, a radially compressed packed bundle of natural bristles in part contained by said ferrule and in part projecting beyond said opposite end of the bore, all said bristles being continuously elongated in substantial overlap with each other with the root ends at substantially the tapered region of the bore, and a hardened bonding material radially permeating said bundle from the root ends to said smaller area and bonding said bristles to said ferrule and to each other in an effectively solid annular root end, the bonding material and adjacent central bristles of said annulus defining a central liquid-supply passage extending at least for the bonded length of those bristles which surround the passage.
Claim 4
Dependent Claim
157 words
As an article of manufacture, a brush comprising an elongated tubular ferrule having a bore open at an inlet liquid-receiving end of larger cross-sectional area than the opposite outlet end, there being a tapered portion of the bore connecting said larger and smaller areas, a radially compressed packed bundle of natural bristles in part contained by said ferrule and in part projecting beyond said opposite end of the bore, all said bristles being continuously elongated in substantial overlap with each other with the root ends at substantially the tapered region of the bore, and a hardened bonding material radially permeating said bundle from the root ends to said smaller area and bonding said bristles to said ferrule and to each other in an effectively solid annular root end, the bonding material and adjacent central bristles of said annulus defining a central liquid-supply passage extending at least for the bonded length of those bristles which surround the passage.
Claim 5
Dependent Claim
164 words
As an article of manufacture, a brush comprising an elongated tubular ferrule having a bore open at both ends, a radially compressed packed bundle of natural bristles in part contained by said ferrule and in part projecting beyond one end of said ferrule, all said bristles being continuously elongated in substantial overlap with each other at least within said ferrule, the portion of said bristles within said ferrule including the root ends of said bristles, a hardened bonding material radially permeating said bundle near the root ends and bonding said bristles to each other in a radially outwardly packed annulus terminated by and bonded to the bore of said ferrule, the bonded length of said bristles being essentially fully contained within said ferrule, the bonding material and adjacent continuous central bristles of said annulus defining a continuous passage through the bonded region of said bristles for central liquid supply from the other end of said ferrule to the unbonded projecting ends of said bristles.
Claim 6
Dependent Claim
164 words
As an article of manufacture, a brush comprising an elongated tubular ferrule having a bore open at both ends, a radially compressed packed bundle of natural bristles in part contained by said ferrule and in part projecting beyond one end of said ferrule, all said bristles being continuously elongated in substantial overlap with each other at least within said ferrule, the portion of said bristles within said ferrule including the root ends of said bristles, a hardened bonding material radially permeating said bundle near the root ends and bonding said bristles to each other in a radially outwardly packed annulus terminated by and bonded to the bore of said ferrule, the bonded length of said bristles being essentially fully contained within said ferrule, the bonding material and adjacent continuous central bristles of said annulus defining a continuous passage through the bonded region of said bristles for central liquid supply from the other end of said ferrule to the unbonded projecting ends of said bristles.
Claim 7
Dependent Claim
30 words
The article of claim 3, in which the bore of said annulus at the bonded region thereof is smooth and continuously cylindrical, being defined by bristles and by bonding material.
Claim 8
Dependent Claim
25 words
The article of claim 4, in which said ferrule is generally cylindrical about a central axis with which the bore of said annulus is coaxial.
