The Philipps Revolver Mechanik Patent
and some of the associated drawings

The patent application under the name of the Frankfurter Musik-Werke was apparently submitted on March 7, 1905, with the patent granted on April 18, 1906. Notice that Leopold King, the actual inventor, is not mentioned anywhere in the patents. The accompanying drawings, while not complete, do represent the idea sufficiently well to insure the patent.
