A machine for finishing parts, having part-isolating means such as vertical partitions or dividers, defining one or more compartments, disposed at least partially within the finishing chamber, each compartment designed to accept a part or parts to be finished and to maintain parts isolated from other parts. The finishing chamber and the part-isolating means are movable with respect to each other. As a result, as the part moves along the finishing chamber during the course of the finishing process, the compartment defined by the part-isolating means, e.g., partitions, moves longitudinally with the part and isolates it from other parts. In one embodiment of the invention, the part-isolating means, such as partitions for defining compartments for the parts, moves vertically with respect to the finishing chamber. Vertical movement is controlled by devices such as solenoids or air-operated cylinders in turn controlled by timers, permitting precise control of the finishing period. The vertical movement is so controlled that at the proper times the parts are released to advance to the space beyond the partition. Thus, in effect, the compartment surrounding the part and isolating it from other parts, moves with the part. In another embodiment the partitions are arranged to move longitudinally with the parts, and means are provided for retarding, stopping, or driving the parts longitudinally. In still another embodiment, means is provided for separating finishing material from the parts and discharging finished parts. The finishing machines may be curvilinear or annular gyratory motion-type machines, linear tub-type machines, or any of various types of tumbling machines. Method of finishing whereby any and all of the foregoing objectives are accomplished. The present application claims such improved finishing apparatus wherein the part-isolating means is supported in the upper-edge region of the finishing chamber or container.
