ABSTRACT:
An improved barrel-type treating apparatus comprising a framework, a foraminous treating barrel having an elongated opening supported at its ends on the framework, and a drive mechanism including a shaft on the framework having a driven gear at one end drivingly coupled to the barrel, a drive gear at the opposite end coupled to the shaft through a slip clutch and a stop arm on the shaft for engaging an abutment at a treating station to limit oscillating movement of the barrel between an angularity of preferably at least about 180.degree. up to an angularity below that at which workpieces are inadvertently discharged from the barrel opening. The gear on the barrel is preferably provided with coacting means to prevent loss of synchronization between the barrel and drive assembly. A secondary drive assembly is also preferably provided for oscillating the barrel through a controlled angularity while in an elevated position above a treating station to facilitate drainage of treating solution from the workpieces.
