Abstract
A rotary brush construction comprised of a drumlike frame having a plurality of replaceable, semi-cylindrical, bristle-carrying sections removably attached thereto. The brush sections are mounted in opposed pairs on the frame. The means attaching the brush sections to the frame can be easily removed and replaced.
Claims5
In a rotary brush construction having rotatable hub means, a plurality of arcuate bristle-carrying brush sections mountable on said hub means, and connecting means for removably mounting the individual brush sections on said hub means, comprising the improvement wherein:
- said hub means includes a pair of axially spaced collars adapted to be mounted nonrotatably upon a shaft, and a pair of circumferentially spaced, axially elongated and substantially parallel connecting elements extending axially between and fixedly connected to said pair of collars, said connecting elements being disposed adjacent the peripheries of said collars;
- said connecting means coacting between the respective brush sections and one of said connecting elements for individually fixedly connecting the brush sections to said hub means;
- and
- said hub means also including a pair of circumferentially spaced and substantially parallel connecting members extending axially between said pair of collars, said connecting members projecting outwardly beyond the peripheries of said collars and including laterally projecting flange means spaced outwardly from the peripheries of said collars and disposed for overlapping the adjacent free edges of the brush sections.
In a rotary brush construction having rotatable hub means, a plurality of arcuate bristle-carrying brush sections mounted on said hub means, and connecting means for removably mounting the individual brush sections on said hub means, comprising the the improvement wherein each said brush section includes an arcuate substantially semi-cylindrical shell having a plurality of bristles mounted thereon and projecting radially outwardly thereof, a pair of said shells being mounted substantially diametrically opposite one another when mounted on said hub means, said connecting means comprising threaded fastener means extending between and fixedly interconnecting each said shell to said hub means, and edge restraining means for preventing the axially extending edges of said shells from deflecting radially outwardly away from said hub means during rotation of said brush contruction, said edge restraining means including a pair of circumferentially spaced and substantially parallel restraining members extending axially of said hub means and fixedly connected thereto, said restraining member being disposed between the adjacent axially extending edges of a pair of said shells and projecting outwardly beyond the periphery of said hub means, said restraining member including laterally projecting flange means spaced outwardly from the periphery of said hub means and disposed for snugly overlapping the adjacent free axially extending edges of the shells.
