ABSTRACT:
A power driven cylindrical rotary brush includes a drive shaft having affixed adjacent to one end a first splined inwardly directed frusto-conical plug having a peripheral flange at its base and having affixed adjacent its opposite end a circular plate having circumferentially spaced tapped bores. A cylindrical brush core provided with helically wound bristles has one end engaging the first plug. A second plug similar to the first plug engages the opposite end of the brush core and is bolted to the circular plate and is urged toward the first plug to wedge and deform the opposite end borders of the core. The first plug may be secured to the shaft in the manner of the first plug.
