(1) Note. Since most sheet piles are of general utility (e.g., retaining walls, foundation, cofferdams, caissons, etc.) all patents with claims not specifically limiting in regard to utility have been classified as original in this and indented subclasses. Those patents claiming method or apparatus restricted to an area other than earth retaining have been placed in the appropriate subclasses above and cross-referenced here.

231+, for piles employed as foundations and methods and apparatus for installing the same.
