Are You Able to Crack It? That Forgotten Dutch Creation That Forged our Modern World
One can find many contenders for the designation as “planet’s most significant invention.” The wheel. The movable type. The combustion motor.
As per a new book, however, that title belongs to the mechanised timber mill invented through Dutchman Corneliszoon van Uitgeest in 1593.
“Prior to mechanised sawing, constructing a modest merchant vessel necessitated approximately ten sawyers laboring over 90 days,” notes Jaime Dávila. “Using wind-powered lumber mills, the same amount of cut lumber could be produced within a week.”
Thanks to their rapid automated cutter, that converted timber into boards using virtually no human effort, Dutch builders were able to construct ships more quickly compared to anyone else, an advantage that sparked one hundred years of Netherlands naval, economic and artistic dominance in Europe and the globe.
The First True Manufacturing Device
Corneliszoon’s lumber mill, argues the writer, represented “humanity’s initial authentic factory apparatus.” A windmill rotated a gear. A single part transformed its rotary movement to up-and-down motion for the cutting blade. A separate mechanism transformed the spinning movement into a sideway’s motion advancing the timber to the blade. A ratchet system shifted the wood ahead one precise increment per cycle.
“Each element was simple by itself. Corneliszoon’s genius lay in how to integrate them so the machine acted in a precisely synchronized order, cutting on every descending motion and advancing on every upward motion. It was a remarkably intelligent application of fundamental parts.”
A fact that brings us up to the current challenge. The task is for you to reinvent a key the basic concepts underpinning this historic machine.
Round and Up
Construct a mechanism which converts rotary movement to vertical action. You have these items exclusively: A rotating disc. Two pins. Two bars. A “sleeve”, that is a cylinder or sleeve into which a single the bars can slide perfectly. (Consider that you can mount components on a stand, so the components don’t collapse.)
I’ll be back at 5pm UK time with the solution.
In the interim, PLEASE NO HINTS. Instead, feel free to suggest (non obvious) candidates for the world’s greatest creation.
