Abstract
Abstract An apparatus capable of applying wax to the side surfaces of a vehicle in an automatic and uniform manner irrespective of the width of the vehicle and without smearing the side windows thereof. It comprises, among others, a guide rail laid on the ground in a position adjacent to one of the side columns of the portal structure for guiding vehicles therethrough and a pair of right and left wax-gun supporting frames, one fixed to the portal structure and the other movable transversely thereof under the control of a sensor mounted on the support frame to feel the adjacent side surface of the vehicle being advanced. Wax guns mounted on the respective support frames with their orifices directed horizontally are each oscillatable about a vertical axis and held spaced a predetermined distance from the vehicle irrespective of the size thereof.

An apparatus for applying wax to the side surfaces of vehicles, comprising: a portal frame structure through which a vehicle can progress, a guide rail laid on the ground under said portal frame structure in a position adjacent to one side thereof to guide the vehicle through said portal frame structure, a wax ejecting system including a pair of wax guns arranged on the opposite side portions of said portal frame structure and having respective orifices directed substantially horizontally and inwardly of said portal frame structure, a first support frame secured to said portal frame structure on that side thereof adjacent to said guide rail, a second support frame hung on said portal frame structure on the opposite side thereof through the intermediary of a parallel link mechanism, two vertical rods journaled on said respective support frames for oscillation about their own axes and respectively supporting said wax guns at substantially the same level, biasing means for normally urging said second support frame to swing outwardly of said portal frame structure, actuator means coupled to said wax ejecting system to operate the same and including a pneumatic actuator operable to cause said second support frame to swing inwardly of said portal frame structure against the bias of said biasing means, sensor means arranged on said second support frame to sense the adjacent side surface of the vehicle progressing through said portal frame structure and operable to control said pneumatic actuator in a manner so that the wax gun associated with said second support frame is held at all times spaced a predetermined distance from the adjacent side surface of the vehicle, and drive means associated with said vertical rods to cause oscillatory rotation thereof about their own axes.
