In 1939, the Henri Selmer Company, a French, family-owned manufacturer of instruments, revolutionized and patented the mechanics for new "Balanced Action" models of trumpets and saxophones.
The patent act of 1790 established the rules for submitting a patent application. Each application had to be submitted with specifications, a patent drawing, and if possible a model of the invention. Eventually, models were no longer required.
The National Archives holds nearly three million patent case files from 1836-1956.
