ABSTRACT:
A chain drive overhead conveyer extends through an oven to move carriages between exit and entrance ends of respective rotary drive shafts that are outside the oven. Driven wheels of the carriages are canted with respect to the rotary drive shafts so that when a drive shaft is rotated, a helical loci of engagement between the drive shaft and engaged driven wheels provides sufficient traction to propel the carriages along the conveying path outside the oven. Weight of loaded carriages is carried through carriage support wheels to a load support structure adjacent to and independently of the rotary drive shafts and the chain conveyer through the conveying path. Heat sensitive portions of the carriages, e.g. the driven wheels, are chilled at the exit of the oven.
