ABSTRACT:
A car wash apparatus having inner and outer, counterrotating curtain assemblies of circular configuration. Each curtain comprises strip elements which at rest are suspended in close proximity to those strip elements of the other curtain. The strips are displaced during travel over the car body resulting in the strips from one curtain intermingling with strips of the other curtain to enhance the strips cleaning action. A drive mechanism powers the curtains through concentric drive shafts with a water supply shown provided through same. Curtain confining means are supported adjacent the curtain paths guiding the curtain strips for rotational travel into desired impingement against the vehicle body. The strip elements may include highly flexible fibrous segments to clean irregular surface areas of the vehicle. Rotary brushes within the inner curtain assembly clean the vehicle sides. Said brushes are powered via a continuous cable carried by said curtain assembly reeved through power take-off pulleys.
