Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
126 words
A perforate basket of the type used with a spin-galvanizing apparatus for galvanizing articles by a process of moving said articles along a workpath and immersing said articles in liquidcontaining tanks and selectively spinning said articles, said perforate basket comprising: a perforate side wall; a plurality of separating grates extending outwardly from a center axis to said perforate side wall to form compartments within said basket for holding articles to be coated; and, a space adapter for location in one of said compartments, said space adapter being adapted to be selectively attached to one of said grates for adapting the width of one of said compartments to accommodate articles that are thinner than those corresponding to the width of said one compartment without said space adapter.
