Patent ID: 8713743

Claim:
A rotary brushing tool comprising: a hub portion having a pair of hub elements, each hub clement including a central opening bounded by a tubular portion extending axially along the central opening, an annular retaining plate portion extending radially outward from the, and a hub channel formed by placing the tubular portions of the hub elements in opposition, the hub channel opening radially outwardly; and a wheel portion including: bristles arranged in the hub channel to extend substantially radially outward from the central opening so as to have a portion of the bristles within the hub channel and a portion of the bristles extending radially outward from the hub channel, a castable material retaining the bristles within the hub channel, the castable material being located substantially entirely within the hub channel and having an unbounded radially outward surface that is fully exposed to the portion of the bristles extending radially outward from the hub channel wherein the bristles are substantially free of the castable material radially outward from the huh channel so that the portions of the bristles radially outward from the hub channel are flexible relative to the portions of the bristles located within the castable material in the hub channel; and wherein the castable material is poured into the hub channel and, when cured, is retained in the hub channel solely by the hub elements and the portion of the bristles within the hub channel, the castable material forming a hub in the hub channel that retains the bristles.
