Cylindrical brush construction

Claim 1

A DISPOSABLE CYLINDRICAL FINISHING BRUSH ASSEMBLY ADAPTED TO BE MOUNTED ON A ROTATABLE SHAFT HAVING A CONTINUOUS EXTERNAL CYLINDRICAL MOUNTING SURFACE AT LEAST AT EACH END OF SAID BRUSH ASSEMBLY, SAID BRUSH ASSEMBLY COMPRISING: (1) A PRE-TWISTED COMPLEMENTARY PAIR OF ELONGATED SEMI-CYLINDRICAL BRUSH STRIP HOLDING MEMBERS PROVIDED WITH (A) A PLURALITY OF PAIRS OF INTEGRAL EXTERNAL RADIALLY PROJECTING LONGITUDINAL EXTENDING RIBS OF UNIFORM CROSS SECTION THROUGHOUT THEIR ENTIRE LENGTHS, (B) SAID RIBS NEAR THE END OF SAID HOLDING MEMBERS BEING REMOVED TO PROVIDE AN OUTER CYLINDRICAL CONTINUOUS SUBSTANTIALLY SEMI-CYLINDRICAL SURFACE, (C) SAID PAIR OF SEMI-CYLINDRICAL MEMBERS EACH HAVING A CONTINUOUS SEMI-CYLINDRICAL INNER SURFACE OF LESS THAN 180*, (D) SAID INNER SEMI-CYLINDRICAL SURFACE HAVING A DIAMETER SUBSTANTIALLY EQUAL TO THE DIAMETER OF SAID CONTINUOUS EXTERNAL CYLINDRICAL SURFACE OF SAID ROTATABLE SHAFT ON WHICH SAID HOLDING MEMBERS ARE TO BE MOUNTED, (E) A PLURALITY OF ELONGATED BRUSHING ELEMENT STRIPS LOCATED BETWEEN ADJACENT PAIRS OF SAID RIBS TO PROVIDE A PLURALITY OF ROWS OF RADIALLY EXTENDING BRUSHING ELEMENTS TO PROVIDE AN UNINTERRUPTED COMPLETELY CYLINDRICAL BRUSHING SURFACE, (F) DEFORMABLE MEANS ALONG SAID RIBS FOR ANCHORING SAID STRIPS BETWEEN SAID ADJACENT PAIRS OF SAID RIBS, (G) SAID SEMI-CYLINDRICAL MEMBERS BEING TWISTED NOT MORE THAN 180* BETWEEN THEIR ENDS, WHEREBY THEIR RIBS EXTEND SLIGHTLY HELICALLY AND SAID BRUSH STRIPS THEREIN FORM A HELICAL PATTERN; AND (2) CIRCUMFERENTIAL REMOVABLE STRAP MEANS SURROUNDING SAID OUTER CONTINUOUS SEMI-CYLINDRICAL SURFACES AT SAID ENDS OF SAID HOLDING MEMBERS FOR FRICTIONALLY CLAMPING SAID PAIR OF HOLDING MEMBERS TO SAID CONTINUOUS EXTERNAL CYLINDRICAL SURFACE OF SAID SHAFT, WHEREBY SAID STRAP MEANS DRAW THE ADJACENT EDGES OF SAID HOLDING MEMBERS, WHICH ARE SPACED BECAUSE THEY ARE LESS THAN 180* IN EXTENT, TOGETHER TO PREVENT SLIPPING BETWEEN SAID MEMBERS AND SAID SHAFT.
