ABSTRACT:
Drying apparatus for an automatic car wash having separate sensing means for detecting the proximity of a nozzle to opaque top portions of vehicles and transparent top portions of vehicles to maintain the nozzle within a preselected proximity range of the top portions of the vehicles. Another sensing means is provided to detect the tailgates of open-bed pick-up trucks to retract the nozzle before it hits a tailgate. Also, the means by which the nozzle is mounted and moved toward and away from the vehicles vary the orientation of the nozzle relative to vertical as the nozzles moves between its uppermost and lowermost positions. Similar mounting and moving means can be used with side drying apparatus. In a second and more preferred form, ultrasonic detectors detect both the opaque parts of a vehicle and the windshield.
