Vibratory cleaning and coating system

Apparatus for treating a plurality of articles adapted to be moved upwardly along the track in a bowl toward an article outlet from the bowl, the improvement comprising, in combination:

• said track extending inwardly from the wall of said bowl, said track being helically shaped and being substantially cantilevered supported from the wall of said bowl, said helical track comprising a series of spaced apart segments extending in sequence toward said article outlet, each of said segments having a planar top surface, the spaced apart portions of preceding segments of said series overlapping the spaced apart portions of succeeding segments of said series, the overlapping portions of the preceding segments being spaced from the wall of said bowl to form drain openings which progressively increase in size in the direction of article flow, said segments being sloped downwardly toward said wall.

Apparatus for treating a plurality of articles adapted to be moved upwardly along a track in a bowl toward an article outlet from the bowl, the improvement comprising, in combination:

• said bowl having a conical bottom wall on which said articles are introduced for subsequent movement toward the lower edge of the wall and toward said track, said track extending inwardly from the sidewall of said bowl, said track being helically shaped and being substantially cantilevered supported from said sidewall, said helical track comprising a series of spaced apart segments extending in sequence toward said article outlet, with the spaced apart portions of preceding segments of said series overlapping the second apart portions of succeeding segments of said series.
