Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
95 words
A car body drying apparatus comprising a frame, a nozzle assembly vertically movably mounted on the frame and adapted to spray drying air, means for constantly biasing said nozzle assembly in the upward direction, means for lowering said nozzle assembly against the action of said biasing means, feeler means connected to said nozzle assembly valve means controlled by said feeler means to control said lowering means and adapted to cause said biasing means to overcome said lowering means when said feeler means is moved beyond a predetermined limit by its contact with the car body.
Claim 2
Dependent Claim
95 words
A car body drying apparatus comprising a frame, a nozzle assembly vertically movably mounted on the frame and adapted to spray drying air, means for constantly biasing said nozzle assembly in the upward direction, means for lowering said nozzle assembly against the action of said biasing means, feeler means connected to said nozzle assembly valve means controlled by said feeler means to control said lowering means and adapted to cause said biasing means to overcome said lowering means when said feeler means is moved beyond a predetermined limit by its contact with the car body.
Claim 3
Dependent Claim
