Can You Crack It? The Forgotten Dutch Invention That Shaped the Modern Globe
There are numerous contenders for the designation as “world’s most significant innovation.” The wheel. The movable type. The steam engine.
According to a new book, though, that title should go to a mechanised sawmill invented through Dutch inventor Corneliszoon van Uitgeest during 1593.
“Prior to automated cutting, constructing a simple merchant vessel necessitated around ten sawyers working over 90 days,” writes Jaime Dávila. “Using wind-powered lumber mills, an identical amount of processed timber might be manufactured in less than seven days.”
Owing to their rapid mechanical cutter, which turned logs to boards using virtually no manual labor, the Dutch could construct ships faster than anyone else, an advantage that unleashed one hundred years of Dutch naval, economic and cultural supremacy across Europe and the world.
The Original True Industrial Device
Corneliszoon’s sawmill, contends Dávila, represented “mankind’s initial true industrial machine.” A wind turbine turned a gear. One component transformed the circular motion into vertical motion to power the saw. A separate mechanism transformed the rotary movement into a lateral motion feeding the timber toward the cutter. A ratchet system shifted the log forward one precise increment each stroke.
“Every component seemed modest on its own. Corneliszoon’s genius lay in how to combine them in order that they acted in a perfectly controlled sequence, cutting on every downward stroke while advancing on every return stroke. It was a remarkably clever use of basic components.”
A fact that leads us to today’s puzzle. I’d like you to reimagine a key the fundamental concepts behind this historic invention.
Circular to Vertical
Design a machine which converts rotary movement to up-and-down motion. You have these components exclusively: A rotating disc. Two pins. Two bars. A “sleeve”, which is a tube or housing through which one of the rods can slide snugly. (Assume it is possible to mount components on a stand, so that the parts don’t fall down.)
I’ll be back at 5pm UK time with the solution.
In the interim, PLEASE NO HINTS. Rather, feel free to propose (less celebrated) contenders for the planet’s most impactful invention.
