Can You Crack It? The Forgotten Dutch Creation That Shaped our Contemporary World
There are numerous contenders for the title of “planet’s most significant innovation.” The wheel. The movable type. The steam engine.
According to a new book, however, that title belongs to the automated sawmill invented by Dutchman Cornelis Corneliszoon in 1593.
“Prior to mechanised cutting, constructing a simple trading ship necessitated approximately 10 sawyers laboring over three months,” writes the author. “Using wind-driven lumber mills, the same amount of cut lumber might be manufactured within a week.”
Thanks to their speedy mechanical saw, which converted timber into boards with virtually no manual labor, the Dutch were able to construct vessels more quickly compared to anyone else, an advantage that sparked one hundred years of Dutch naval, economic and cultural dominance across Europe and the globe.
The First True Industrial Device
The inventor's sawmill, argues Dávila, was “humanity’s first true industrial apparatus.” A wind turbine rotated a wheel. One component transformed the rotary motion to up-and-down action for the saw. A separate mechanism changed the rotary movement into a sideway’s motion feeding the log to the blade. A ratchet system moved the log ahead a measured step per cycle.
“Each element seemed simple on its own. Corneliszoon’s brilliance was to integrate these parts in order that the machine operated within a precisely synchronized sequence, sawing on every descending stroke while moving with each return stroke. It was a remarkably clever use of basic parts.”
A fact that leads us to the current puzzle. I’d like you to reinvent a key the basic concepts behind this historic invention.
Circular to Vertical
Design a machine which converts circular motion to vertical motion. Your available these components exclusively: A spinning wheel. Two pegs. Two rods. A “sleeve”, that is a tube or sleeve into which a single the rods will fit perfectly. (Consider that it is possible to mount components on a stand, so that the parts don’t fall down.)
I’ll be back at 5pm UK with the solution.
Meanwhile, NO SPOILERS. Instead, please suggest (less celebrated) candidates as the world’s most impactful invention.
