Patent Examiner Notebooks
Vintage "Slinky" patent drawing from 1946. Invented by Richard T. James the "Slinky" is a child's toy composed of a compressed helical spring. This simple contraption can perform a number of amazing tricks, including travelling down a flight of steps end-over-end as it stretches and re-forms itself with the aid of magic and its own infinite powers.
