Abstract
Abstract A tool for scarifying the ends of pipe or the like includes a generally rigid body member adapted to be held in a person's hand for manipulation. The body member has opposite ends and includes a longitudinal axis extending across such ends. Wire brushes are secured to the body member against axial and rotational movement relative thereto in outwardly extending relationship to the opposite ends, and with the longitudinal axes of the brushes extending generally parallel to the longitudinal axis of the body member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
135 words
A tool for scarifying at least the ends of generally cylindrical areas comprising; a generally rigid body member having a longitudinal axis extending across opposite ends and being adapted to be held in a person's hand for manipulation, wire brushes manufactured separate from said body member and being secured to said body member against axial and rotational movement relative thereto in outwardly extending relationship to said opposite ends, said brushes having longitudinal brush axes extending generally parallel to said longitudinal axes of said body member and having generally circular cross-sectional configurations perpendicular to said brush axes, and at least one hole in said body member intermediate said ends extending transversely of said body member and being lined with abrasive material for receiving the ends of generally cylindrical members to abrade the exterior surfaces of same.
Claim 2
Dependent Claim
135 words
A tool for scarifying at least the ends of generally cylindrical areas comprising; a generally rigid body member having a longitudinal axis extending across opposite ends and being adapted to be held in a person's hand for manipulation, wire brushes manufactured separate from said body member and being secured to said body member against axial and rotational movement relative thereto in outwardly extending relationship to said opposite ends, said brushes having longitudinal brush axes extending generally parallel to said longitudinal axes of said body member and having generally circular cross-sectional configurations perpendicular to said brush axes, and at least one hole in said body member intermediate said ends extending transversely of said body member and being lined with abrasive material for receiving the ends of generally cylindrical members to abrade the exterior surfaces of same.
Claim 3
Dependent Claim
45 words
The tool as defined in claim 1 wherein said body member has opposite outer surfaces across which said hole extends, flanges extending inwardly of said hole adjacent said outer surfaces, and said abrasive material being on a carrier positioned in said hole between said flanges.
Claim 4
Dependent Claim
65 words
the tool as defined in claim 1 wherein said body member is formed in a pair of parts joined together on joining surfaces extending generally parallel to said longitudinal axis of said body member, said brushes having mounting means positioned between said parts along said joining surfaces and said mounting means being positionable between said parts and removable therefrom only when said parts are separated.
Claim 5
Dependent Claim
16 words
The tool as defined in claim 3 wherein said pair of parts are substantially identical halves.
Claim 6
Dependent Claim
141 words
A half part cooperable with a like part to form a body member for a hand held scarifying tool, each said part having opposite joining and outer surfaces and opposite ends, a hole through said part intermediate said ends across said joining and outer surfaces, a flange extending inwardly of said hole adjacent said outer surface, and receiving means in said joining surface extending inwardly from at least one of said ends for receiving a mounting means on a scarifying device, said half part being cooperable with said like part by joining the parts together with their joining surfaces in engagement after a mounting means on a scarifying device is positioned therebetweeen for reception in said receiving means, the parts having the holes therein aligned for receiving an abrasive material carrier between the flanges adjacent the outer surfaces of the parts.
Claim 7
Dependent Claim
141 words
A half part cooperable with a like part to form a body member for a hand held scarifying tool, each said part having opposite joining and outer surfaces and opposite ends, a hole through said part intermediate said ends across said joining and outer surfaces, a flange extending inwardly of said hole adjacent said outer surface, and receiving means in said joining surface extending inwardly from at least one of said ends for receiving a mounting means on a scarifying device, said half part being cooperable with said like part by joining the parts together with their joining surfaces in engagement after a mounting means on a scarifying device is positioned therebetweeen for reception in said receiving means, the parts having the holes therein aligned for receiving an abrasive material carrier between the flanges adjacent the outer surfaces of the parts.
Claim 8
Dependent Claim
22 words
The part as defined in claim 5 including a narrow rib extending along said hole between said flange and said joining surface.
Claim 9
Dependent Claim
97 words
A hand held scarifying tool comprising; a substantially rigid body member having a longitudinal axis, opposite outer surfaces and opposite ends, scarifying devices manufactured separate from said body member and secured thereto against rotational and axial movement in outwardly extending relationship to said opposite ends, a hole through said body member across said outer surfaces intermediate said ends, abrasive material lining said hole, said body member being formed from two parts joined together along joining surfaces extending across said ends substantially parallel to said outer surfaces, said scarifying devices having mounting means trapped between said joining surfaces.
Claim 10
Dependent Claim
97 words
A hand held scarifying tool comprising; a substantially rigid body member having a longitudinal axis, opposite outer surfaces and opposite ends, scarifying devices manufactured separate from said body member and secured thereto against rotational and axial movement in outwardly extending relationship to said opposite ends, a hole through said body member across said outer surfaces intermediate said ends, abrasive material lining said hole, said body member being formed from two parts joined together along joining surfaces extending across said ends substantially parallel to said outer surfaces, said scarifying devices having mounting means trapped between said joining surfaces.
Claim 11
Dependent Claim
33 words
The tool as defined in claim 7 including flanges extending inwardly of said hole adjacent said outer surfaces, and said abrasive material being on a carrier received in said hole between said flanges.
Claim 12
Dependent Claim
30 words
The tool as defined in claim 8 including a narrow rib extending along said hole between said flanges, said carrier having carrier ends located on opposite sides of said rib.
