Abstract
Abstract On demand car wash conveyor apparatus for installation in a tire path of a car to be washed and having a retraction trench extending therealong. The conveyor apparatus includes an endless chain extending along the tire path adjacent such trench and has a plurality of longitudinal mounting pin means spaced longitudinally therealong. A plurality of sets of first and second shafts are pivotally mounted on their respective one extremities from the respective pin means and are pivotable between an operative position projecting transversely over the tire path and a retracted position extending vertically into the retraction trench. A plurality of sets of pusher and support rollers are mounted from the respective first and second shafts and the pusher rollers are disposed above the level of the support rollers when the shafts are in their operative positions. Further, a plurality of strut means are pivotally connected on their respective one extremities with the respective pin means and project forwardly and outwardly therefrom to have their respective opposite extremities connected with the free ends of the respective first shafts to thereby provide support against the bending moment applied to such respective shafts when they are engaged behind the wheel of a car to be pushed through a car wash apparatus.

Total Claims: 9
Claim 1
Independent Claim
291 words
On demand car wash conveyor apparatus for installation on a wheel path of a car to be washed and having a retraction trench extending therealong, said apparatus comprising: endless conveyor chain means for extending over said car path and including a drive run extending adjacent said trench; a plurality of mounting brackets spaced along said drive conveyor chain and each extending longitudinally along said run; longitudinally elongated pivot pins mounted from said mounting brackets; a plurality of sets of first and second shafts mounted on their respective one extremities to the lead ends of said respective pivot pins and pivotable between an operative Position projecting horizontally over said wheel path and a retracted position having the free extremities thereof extending into said trench; a plurality of sets of pusher and support rollers mounted on said respective first and second shafts with said pusher rollers being disposed above said support rollers when said shafts are in said operative positions; and a plurality of strut means disposed behind said respective sets of shafts, connected on their respective one extremities with the respective rear trailing extremities of said respective pivot pins and projecting forwardly to connect on their respective opposite extremities with the free ends of said respective first shafts whereby said chain means may be rotated and said sets of rollers individually directed to said operative or retracted positions depending on the demand therefor and the sets of rollers in said operative position will be carried on said respective support rollers to engage said respective pusher rollers with car wheels disposed in said wheel path and said respective strut means will brace said free extremities of said respective first shafts as said respective car wheels are pushed forwardly by said respective pusher rollers.
