Can You Crack This? That Overlooked Dutch Invention That Shaped the Contemporary World
One can find numerous contenders for the title of “planet’s greatest invention.” The circular axle. The movable type. The steam engine.
According to a recent publication, though, that title belongs to a automated timber mill conceived through Dutch inventor Corneliszoon van Uitgeest during 1593.
“Before mechanised sawing, constructing a modest trading ship necessitated approximately 10 sawyers laboring over three months,” notes Jaime Dávila. “Using wind-driven sawmills, the same quantity of processed timber could be manufactured in less than seven days.”
Owing to their rapid mechanical cutter, which converted timber to boards using almost no manual labor, the Dutch could build vessels faster compared to anyone else, an advantage that unleashed one hundred years of Netherlands naval, financial as well as cultural dominance across the continent and the world.
The First True Industrial Machine
The inventor's sawmill, contends the writer, was “humanity’s first authentic factory machine.” A windmill rotated a gear. One component converted its circular motion into vertical motion to power the cutting blade. A separate mechanism changed that same rotary movement into a lateral movement feeding the timber to the cutter. A geared mechanism shifted the log ahead a measured step each stroke.
“Every component was simple on its own. Corneliszoon’s genius was to integrate these parts in order that they acted within a perfectly controlled sequence, cutting with each descending stroke and advancing on every upward motion. It was a remarkably clever use of basic components.”
A fact that leads us to the current challenge. I’d like you to reinvent a key the basic concepts behind Corneliszoon’s machine.
Circular to Vertical
Design a mechanism that turns rotary motion to up-and-down motion. You have these components exclusively: A rotating disc. Two pegs. Two bars. A “sleeve”, which is a cylinder or sleeve into which a single the bars can slide perfectly. (Consider that it is possible to mount components on a base, so that the components don’t fall down.)
I’ll be back at 5pm UK with the solution.
Meanwhile, PLEASE NO HINTS. Instead, please propose (non obvious) candidates for the world’s most impactful invention.
