This patent purports to have resulted from a patent filed 23 Aug 1918, using serial number 251184, having been "renewed". This would not be odd, in and of itself, though Patent US-1918-1371204 likewise refers to 23 Aug 1918, via serial number 251184, and results from the earlier patent having been "divided". The usages are rather particular, and do not usually contradict each other, as we are fleshing out on page serial number. This patent uses filing date January 24, 1921 and serial number 439710.
