Sprocket and rollers for log chain conveyor mechanism of an automatic carwash system

A reversible roller assembly for a carwash conveyor system, comprising:

• a lug formed of unitary one-piece construction, the lug including a main body portion having a hole formed therein, a coupling portion for linking together leading and trailing segments of a conveyor chain of the carwash conveyor system, a first nose extending forwardly of the main body portion and beyond a leading end of the coupling portion, and a second nose extending rearwardly of the main body portion and beyond a trailing end of the coupling portion, wherein each of the first and second noses includes a top surface that is ramped upwardly to the main body portion;
• an axle pin extending through the hole in the main body portion of the lug;
• and
• multiple roller wheels rotatably mounted to the axle pin, at least one of the roller wheels positioned on each side of the lug,
• wherein the roller assembly can be detached from the conveyor chain, then reversed and reattached to the leading and trailing segments of the conveyor chain so that the first nose extends rearwardly of the body portion and the second nose extends forwardly of the body portion.
