Can You Crack It? That Overlooked Netherlands Invention That Shaped our Modern World
There are many contenders to claim the title of “world’s most significant invention.” The circular axle. The printing press. The steam engine.
As per a recent publication, though, that title should go to a mechanised sawmill invented through Dutchman Corneliszoon van Uitgeest in 1593.
“Before mechanised cutting, building a modest merchant vessel required approximately 10 lumberjacks working over 90 days,” writes Jaime Dávila. “With wind-powered lumber mills, an identical quantity of processed timber could be manufactured in less than a week.”
Thanks to their speedy mechanical cutter, that converted logs to boards using virtually no human effort, Dutch builders were able to build vessels more quickly than anyone else, which unleashed one hundred years of Dutch maritime, economic and cultural supremacy in the continent and the world.
The First Genuine Industrial Machine
Corneliszoon’s sawmill, contends Dávila, was “humanity’s first authentic industrial machine.” A windmill rotated a wheel. A single part converted the rotary movement to vertical action for the cutting blade. A separate mechanism transformed that same rotary movement into a lateral motion feeding the timber to the blade. A geared mechanism moved the log ahead one precise increment each cycle.
“Every component was simple by itself. Corneliszoon’s brilliance lay in how to integrate them so the machine acted within a perfectly controlled order, cutting on every descending motion while advancing on every return stroke. This constituted an astonishingly clever use of basic parts.”
A fact that leads us up to the current challenge. I’d like you to reinvent a key the fundamental concepts behind this historic invention.
Circular to Vertical
Construct a machine which converts circular motion into up-and-down action. Your available these items exclusively: A spinning wheel. Two pegs. Two bars. A “guide”, that is a cylinder or sleeve into which a single the rods can slide snugly. (Assume you can mount components on a base, so the parts don’t collapse.)
I’ll be back later today UK time with the answer.
Meanwhile, NO SPOILERS. Instead, feel free to suggest (less celebrated) contenders for the planet’s greatest invention.
