This patent deals with airplane frame design and the issue of where to house the motor.
Hans Baumeister is the applicant here, though he wasn't on the original German filing, which only named Zeppelin-Werke. We don't know to what extent he is the inventor or a corporate representative. His location is not Staaken, but Friedrichshafen, not Staaken, home of Luftschiffbau Zeppelin.
