This Da Vinci - esque illustration was discovered amongst the tossed around debris at the abandoned Atlas Tack factory in September 1987. After the facility abruptly closed, vandals had a free-for-all inside the building and ransacked the entire premises for years. This drawing dated 6/14/1939 and signed by Carl B. White appears to be a proposed machine to mass produce bottle caps, complete with a conveyor belt and automatic counter using sensor lights. This clever design boasted 3,000 caps per minute and could pour out 50 gross per container at the end of the conveyors tray. There is no evidence that the company ever got into bottle cap manufacturing, especially with WW II right around the corner. MLBaron Archives.
