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; probably there is more than one German patent related to optics for navigation. We also have a growing number of patents leading to a target Patent DE-1907-09-03 Siemens-Schuckert Werke GmbH, as does this patent. There were quite likely indeed a few separate patent filed by this firm on 1907-09-03, covering various material. They will have to be differentiated.

The frontmatter of this patent refers also to a German patent filed 23 May 1908.
