We need more work on Joseph Hofmann before we determine the manner in which this patent relates to his others.

We are fleshing out “compression”, here, somewhat in opposition to rarefaction. On earlier theory, on the use of this word in this specific manner, we have Armour, 1876, Air compression under wing-planes.

  • “Publication/disclosure” will be treated as “date granted”, for now. The “Megjelent (year). évi (month) hó (day)-én (or án)”, that is “Released (month) (day), (year)”, given on the original, is seemingly always later, and we do not know which legally constitutes the patent’s being “granted”. Fortunately, filing date data is clean and simple and consistent between the data page and the original.

The original Hungarian reads “F. Gaebert Berlini Czég Mint Hofmann József Császári Kormánytanácsos Jogutódja Berlinben”, with an overall translation as “F. Gaebert Berlin Company As the Successor(likely legal successor) to the Imperial Government Counselor József Hofmann in Berlin”. Breaking this into particles leads to some ambiguity.
