DESCRIPTION:

On this original linen-backed lithograph from 1932 (includes original specification sheet), James Martin patented a wind direction indicator for aerodomes and like places. James Martin was born in Crossgar, County Down. He was an engineer by the time he was twenty years old, and shortly afterwards, designed a three-wheeled enclosed car. He went to London in 1924 and invented various types of machines. In 1929 he moved to Middlesex, to what is now known as the Martin Aircraft Works. The company built a plane, the MB1. James Val Baker joined the company as a partner and they began to design fighter planes for the Royal Air Force, the MB2 and the MB3. Captain Baker was killed trying to land the MB3, and this may have been a reason why Martin focussed his energy on methods of saving pilots' lives. The MB4 and the MB5 aircraft were developed. Many of Martin's inventions, such as gun mountings and barrage-balloon cable cutters were produced. Many pilots were unable to escape from their cockpits during the Battle of Britain because the canopies would not open when damaged, and Martin devised a way of blowing the canopy off the aircraft. The Ministry of Aircraft Production invited Martin, in 1944, to develop an invention which would improve the survival rate of pilots, and he invented the ejector seat. It was so successful that by 1947, MB ejector seats were being fitted in all British military jet aircraft. He was awarded two honorary doctorates and an OBE and he was knighted. He won the Wakefield Gold Medal of the Royal Aeronautical Society, the Laura Taber Barbour Air Safety Award, the Cumberbatch Air Safety Trophy (1959) and the Royal Aero Club Gold Medal in 1964.

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.
