"This invention relates to improvements in typewriters and more particularly to a typewriter of such character that speed and volume of work are of secondary importance, but with which cost and educational value are of prime importance. . . . One of the objects of the invention is to provide a typewriter which may be manufactured at relatively small cost due to the fact that many moving parts of conventional typewriters are eliminated."--Joseph Lee Sweeney. Filed with the United States Patent and Trademark Office May 13, 1938.
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.
