ABSTRACT:
A rotary scraper device for treating a work surface, comprises a generally cylindrical hollow hub casing having a peripheral wall. The hub casing has a closed end wall and open opposite end with a cover plate removably mounted on the open end of the hub casing, and a shaft extending axially outward of the cover plate for rotating the hub casing axially in one direction. Spaced walls inside the hub define chordal channels opening at the peripheral wall. The channels terminate at axially disposed sleeves inside the hub casing. Springy U-shaped clips have cylindrical bights fitted in the sleeves and springy side walls abutting spaced walls of the channels. Springy ends of the clips extend outwardly beyond the peripheral wall of the hub casing. Straight springy shanks of the fingers fit turnably in coplanar array inside the clips axially of the hub casing. Knuckles at ends of the fingers fit in the cylindrical bights axially of the hub casing. The springy shanks of the fingers extend outwardly beyond the springy side walls of the clips. The outer ends of the clip walls support the springy shanks when they are flexed. The hub can be axially shorter than one half inch so that the springy fingers can scrape narrow surfaces and can enter narrow corners and crevices.
