In keeping with our observations on patent dates, we are treating the "Patentirt im Deutschen Reiche vom" 1918-10-06 shown on this original as exactly one day after the filing date.
This is „Zusatz zum Patent 310170.“ Additional reference is made: „Das Hauptpatent hat angefangen am 4., September 1917.“ This is the „Patentirt im Deutschen Reiche vom“ shown on the original of Patent DE-1917-310170.
Deepl translates „Das Hauptpatent hat angefangen am 4., September 1917.“ as “The main patent started on September 4, 1917.” ; that is, „Patentirt im Deutschen Reiche vom“, one day after filing date, has to do with the patent's being “started”, perhaps legalistically, within Germany, though the actual filing date is still internationally binding.
