Patent US-1909-1250262

This patent document reflects a "renewal", and one might say a mere renewal, and therefore this page has been moved in accordance with its initial filing , though we may expect that an earlier document, would have also reflected an earlier date granted than the one shown on this retrospective document. Also, I'm leery of treating "full specification filed", on an American patent, as analogous to British Complete Specification, because the reasoning behind these internationally variable phraseologies isn't as neatly analogous as we might wish. -AvionHerbert
