Control Device Movable Machine Part Carl Zeiss Original Patent Lithograph 1933
On this original linen-backed lithograph from 1933 (includes original specification sheet), Carl Zeiss, a body corporate, incorporated under the laws of Germany, patented improvements in devices for controlling a movable machine part. Carl Zeiss (11 September 1816 – 3 December 1888) was a German scientific instrument maker, optician and businessman who founded the workshop of Carl Zeiss in 1846 which is still in business today as Carl Zeiss AG. Zeiss gathered a group of gifted practical and theoretical opticians and glass makers to reshape most aspects of optical instrument production. His collaboration with Ernst Abbe revolutionized optical theory and practical design of microscopes. Their quest to extend these advances brought Otto Schott into the enterprises to revolutionize optical glass manufacture. The firm of Carl Zeiss grew to one of the largest and most respected optical firms in the world.
All patent lithographs sold by Maymont Group are 100% ORIGINAL.
These documents are NOT reproductions or posters (patent art).
These are the original lithographs found in books obtained from the Patent and Trademark Office directly.
In the 1800's and early 1900's, inventors would submit a detailed drawing of the invention and/or improvements to the patent and trademark office. Once received and if approved, the Patent office would then send a letter of confirmation to the inventor and begin to take that drawing and etch it into stone in order to create and print this linen-backed lithograph. These documents are the original hard copies that were created by the patent office's artists, and act as patent examiner reference material. With that being said, these are 100% original and are the only physical copies in existence.
