Can You Crack It? The Overlooked Dutch Invention That Forged our Modern World
One can find many contenders to claim the title of “planet’s most significant innovation.” The circular axle. The printing press. The steam engine.
As per a new book, however, that honor should go to a mechanised timber mill conceived through Dutch inventor Corneliszoon van Uitgeest in 1593.
“Before automated sawing, constructing a simple trading ship necessitated around 10 sawyers laboring for 90 days,” notes Jaime Dávila. “Using wind-driven sawmills, the same amount of cut lumber could be produced within seven days.”
Owing to their rapid automated cutter, that turned timber to planks using virtually no manual labor, Dutch builders could build ships faster than anyone else, which unleashed one hundred years of Netherlands maritime, financial and artistic dominance across Europe and the world.
The First True Industrial Device
Corneliszoon’s sawmill, contends Dávila, was “humanity’s first true industrial machine.” A windmill rotated a gear. One component transformed its circular motion to up-and-down motion to power the cutting blade. Another component transformed that same rotary movement into a lateral movement advancing the timber toward the cutter. A ratchet system shifted the wood forward a measured step per stroke.
“Each element seemed modest by itself. The Dutchman’s genius lay in how to combine them in order that they operated within a perfectly controlled sequence, cutting with each descending motion while advancing with each return stroke. This constituted a remarkably intelligent application of basic components.”
A fact that leads us up to the current puzzle. The task is you to reinvent a key the fundamental ideas behind this historic machine.
Round and Up
Construct a mechanism that turns circular movement to up-and-down action. Your available these items only: A rotating disc. Two pegs. Two bars. A “sleeve”, that is a cylinder or sleeve through which one of the bars can slide snugly. (Assume you can mount components on a base, so the components do not fall down.)
I’ll be back later today UK time featuring the answer.
Meanwhile, NO SPOILERS. Instead, feel free to propose (non obvious) candidates as the planet’s greatest invention.
