Tire brush

Claim 1

Improvements in a rotary tire brush for a vehicle washing appartus, said tire brush having an axially elongated central support shaft, and a plurality of bristles which are anchored relative to and project radially outwardly from said central shaft, said bristles being arranged in a cylindrical array which concentrically surrounds and extends axially along the central shaft, comprising the improvement wherein: said plurality of bristles including a first plurality of abrasive bristles which are anchored to said central shaft and project radially outwardly therefrom both circumferentially and axially thereof for defining a first cylindrical array which concentrically surrounds the central shaft and extends axially therealong, said first cylindrical array having a first outer diameter as defined by the radially outer tip ends of said abrasive bristles; said plurality of bristles including a second plurality of stiff nonabrasive bristles which are anchored to said central shaft and project radially outwardly therefrom both circumferentially and axially for defining a second cylindrical array in concentric and axially extending relationship relative to said central shaft, said second cylindrical array having a second outer diameter as defined by the radially outer tip ends of said nonabasive bristles, said second outer diameter being significantly larger than said first diameter; the abrasive bristles of said first cylindrical array being interspersed in a uniform pattern both axially and circumferentially within the nonabrasive bristles defining said second cylindrical array so that said first and second cylindrical arrays extend axially between substantially the same axial limits; and the tip ends of only the non-abasive bristles being flagged to define a plurality of filament-like elements which project inwardly along the nonabasive bristle through a short radial extent so as to define on the tip ends of the nonabrasive bristles an outer fluffy layer.
