"My invention has for its object a tracing device adapted to trace on a transparent surface all the lines, symbols, drawings, letter-press which may be desired and to wipe them out instantaneously. . . .This arrangement, which is capable of many applications for advertising purposes, for moving pictures, toys, testing means for instance, is constituted chiefly by a fluid tight case provided in its upper part with a translucent surface of glass or the like material. . . and may be immediately wiped out through a mere turning of the case upside down associated with a shaking of the latter."--Arthur Grandjean. Filed with the United States Patent and Trademark Office July 23, 1959.
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.
