This is an instrument for making precise visual measurements related to the motion of an aircraft. An arrangement using suspension and a gyroscope can be used to give added stability during movement.
The description relates to Patent DE-1907-204239, filed 1907-09-04, but the illustration is quite different; it probably derives from another patent—cited in the frontmatter, but yet to be identified in this database—dated 23 May 1908.
This French original refers to a purportedly 1907-09-03 German filing, as well as to that of 1908-05-23. The German innovations are possibly being consolidated into this one French patent.
