It seems that we have a date granted, on the original, and a date published, though not an application date, as such. There is not absolute consistency across the German documents we've examined. There is sometimes the articulation of three dates. 1918/03/16 is treated by Espacenet as the priority date for this patent.
This firm specialized in air-cushion shock-absorbers. “Luftfederung” translates as “air suspension”. It is more elaborately defined in German as “Federung von Kraftfahrzeugen, bei der Luft zur Dämpfung von Stößen eingesetzt wird”. This latter translates as “motor vehicle suspension that uses air to absorb shock”.
