Collection descriptions
DATE:
1920-1984
SUMMARY:
Archival materials documenting five of Mount's numerous inventions: the solar still, a jet power burner, turnbuckles and swivel connectors for boats, the "wadnut" (a self-tightening fastener), and a method of joining industrial piping. The papers include notes on concepts, and on testing and prototypes; correspondence with patent attorneys and potential industrial users of the devices; photographs; biographical information on Mount; and a general subject file on his inventions.
SCOPE AND CONTENTS:
Mount had a great range of interests in his inventing career, from children's toys to military equipment and industrial devices, such as pipe-joining processes and patented sailing-boat hardware. He was issued more than 20 U.S. patents as well as patents from Britain, Canada, France, Australia and other countries. The progress of his work on these projects is recorded in the various documents and photographs that constitute this collection. The records in this collection were selected from among some 50 cubic feet of material, as being most representative of Mount's work. Retained were records providing biographical information about Mount and his career as an inventor; his general subject files, which document the wide range of his interests; and a sample of files fully documenting five of his major inventions, three of which were commercially successful and the other two were not. Of particular interest are the numerous documents detailing Mount's efforts, often over decades, in developing inventions. Notes on the concepts, testing of models and prototypes, and voluminous correspondence with patent attorneys, potential industrial users of the devices and photographs of equipment constitute the bulk of the collection. Several projects stand out as Mount's major efforts: solar stills (which store the sun's heat), a jet power burner, turnbuckles and swivel connectors for boats, the "Wadnut" (a self-tightening fastener) and, most importantly, a method of joining industrial piping.

BIOGRAPHICAL / HISTORICAL:
Wadsworth Walton Mount (1907-1985), son of a Baptist minister and businessman, was born in Minnesota, raised in Millington, NJ, attended public schools and was graduated from Amherst College in 1928 with a major in economics and philosophy. Employed in Wall Street as a stock salesman and statistician, he traveled as a public utilities analyst. On the death of his father (1931) he took over management of the family wood-working business, which failed in 1932. After completing the liquidation, Mount was employed by a New York printer and publisher of financial publications. During World War II he was engaged in developing an anti-aircraft gun and a rocket-propelled grapnel for the armed forces. Following the war he became a full-time inventor, working independently in the basement of his Warren, NJ home. He also worked occasionally as a consultant to industrial companies.
