"My invention relates to toys primarily intended for amusement of children, but also for family use as parlor games and the like, and for advertising purposes. . . . A purpose of my invention is to provide a helical spring toy which will transfer its turns from one end to the other in an entertaining manner when it is bent into general semi-circular form and the ends are moved up and down."--Richard T. James. Filed with the United States Patent and Trademark Office August 21, 1946.
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.
