The Espacenet results column gives this American patent the priority date 1913-02-18. Otherwise we have reason to associate this patent with a family descending from Patent FR-1912-458772. Its diagrams and other content do in fact match those of the earlier French patent. Here we have a case again in which the priority date data given on Espacenet for a particular patent is actually merely the filing date for the later patent itself.
