Claims

1. A rotatable brush comprising a cylindrical core, a preassembled brush strip means helically wound on said core in one direction* and accumulator means mounted on said core adjacent to and coupled to one end of said brush strip means, said accumulator means continuously and positively taking up slack in one direction in said brush strip means that accumulates during operation of the brush and holding said brush strip means taut on said core, further said accumulator means preventing rotation of said strip means in the direction opposite to the direction of the helical winding while continuously permitting displacement of said one end of the brush strip means in the direction of the helical winder.

2. The brush of Claim 1 wherein said accumulator means comprises a one-way clutch coupled to said sweeping section end.

3. A rotary brush comprising a cylindrical core, a helical sweeper section including a helically extending base channel registering with said core and bristles carried by said channel and radially projecting therefrom, and means mounted on said core and coupled to at least one end of the sweeper section for preventing the rotation of said sweeper section on said core in one direction, while permitting rotation thereof in the opposite direction*

4. A brush as claimed in Claim 3, wherein said means comprises a one-way clutch coupled to said sweeping section end*

5. A brush as claimed in Claim 3, wherein said means comprises a spring in tension coupled to one end of said sweeper section and the other end coupled to said core.

6. A brush as claimed in Claim 4!, wherein said clutch is removably mounted on the core proximate the end of the 40586/2

7. A brush as claimed in any one of Claims 3 to 6, wherein the base channel of said bristle section has an arm extending outwardly therefrom and having generally the same curvature thereof, and said means engaging said arm.

8. A brush as claimed in any one of Claims 3 4, 6 and 7, wherein said means engages the base channel of said sweeper section*

9. A brush as claimed in Claim 4, wherein said clutch includes a pivoted piece biased in a closed position and pivoted in response to movement of said sweeper section in passing through said means in the direction of rotation of the sweeper section.

10. A brush as claimed in any one of Claims 3, 4, and 7 to 9, wherein said means includes a body having an axial passageway for receiving an end of said sweeper section, a piece spring-loaded to abut the end of said body remote from the entrance of said sweeper section into said body, and which has an edge extending into the passageway.

11. A brush as claimed in Claim 10, wherein said piece has an elongated opening through which passes a bolt received into said body, said body end having an extending surface substantially at right angles to the axis of said passageway, said piece pivoting along said extending surface.

12. A brush as claimed in Claim 7, wherein the one end of the sweeper section coupled to said means is the end towards which the sweeper section would advance if rotated, and said arm being of a length at least equal to the slack of the Sweeper element o said core.

13. brush substantially as described herein with reference to and as illustrated by the accompanying drawing. For the Applicants DR. REIKHOLD COffii AND PARTNERS
