Dish Washing Machine Hobart Manufacturing Company Original Patent Lithograph 1932
On this original linen-backed lithograph from 1932 (includes original specification sheet), The Hobart Manufacturing Company patented improvements in or relating to machines, for washing dishes and other articles. Hobart was founded in 1897 as the Hobart Electric Manufacturing Company in Troy, Ohio, by Clarence Charles Hobart (1855-1932). To increase motor sales, the company attached motors to coffee mills and meat grinders, creating a powered food production machine.
The company reorganized in 1913 as The Hobart Manufacturing Company and became Hobart Corporation in 1974. The former Kitchen Aid division was formed in 1919. In 1934 Hobart bought the Dayton Scale Company (an IBM division) from IBM. Dart & Kraft acquired Hobart in 1981. Kitchen Aid was sold to Whirlpool Corp. in 1986 after getting an offer, for $150 million in January 1985. Dart & Kraft split in 1986, with Hobart becoming part of Premark. Premark was acquired by Illinois Tool Works in 1999. In 2001, Hobart became a part of Illinois Tool Works Food Equipment Group.
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.
