A conveyor system for transporting items between specified work locations within a building is disclosed. The conveyor system includes a continuous guide track including a continuously moving drive chain and individual floor supported carts that move along the guide track. The individual carts have a retractable drive pin assembly that cooperates with disengaging rails mounted adjacent the guide track to allow the carts to stop at certain locations along the guide track. The individual carts have a retractable guide pin assembly that cooperates with selectively retaining means mounted thereon and cams mounted adjacent the guide track to retract the guide pin to allow the carts to be rotated at work stations or oriented in a sideways configuration to save space along the guide track. The carts also have a platform for supporting the items that is adjustable in height.

A spraying system for applying a coating to articles includes a spray booth having a back, a reciprocating spray gun, and an exhaust fan to pull atmosphere from within the spray booth through said back to collect undeposited spray coating material and to exhaust solvent vapors released within the spray booth. The back is movable and has a vent opening having an area substantially smaller than the area of the back, the remainder of the back being impervious to booth atmosphere. The spraying system also includes means for reciprocating the movable back in synchronism with the reciprocating spray gun so that said vent opening is maintained directly before the spray gun during operation.
