Description: |
| James A. Paulaskas' 1977 book, "Additional Improvement Patents, 1837-1861", provides completely different information on AI3 then what is shown here, which is taken straight from the USPTO database. It gives the AI patent issue date as 1838-02-22, and is an additional improvement on patent X8,389 to William Woolley, "bedstead for the sick". |
