Are You Able to Crack This? That Overlooked Dutch Invention That Shaped the Modern Globe
There are numerous contenders to claim the title of “world’s most significant innovation.” The wheel. The movable type. The steam engine.
According to a recent publication, though, that title should go to a automated timber mill invented through Dutch inventor Corneliszoon van Uitgeest during 1593.
“Before mechanised sawing, building a simple trading ship necessitated around 10 sawyers laboring over three months,” writes the author. “Using wind-powered sawmills, the same amount of processed timber might be manufactured in less than a week.”
Owing to their rapid automated saw, that turned timber to boards with almost no human effort, the Dutch could construct ships more quickly than any other nation, which sparked a century of Dutch maritime, financial and cultural supremacy in the continent and the globe.
The First True Industrial Machine
Corneliszoon’s lumber mill, contends Dávila, represented “humanity’s initial true factory apparatus.” A windmill rotated a gear. A single part converted its rotary movement to vertical motion to power the cutting blade. Another component transformed that same spinning motion into a lateral motion feeding the log to the cutter. A geared mechanism moved the wood ahead one precise increment per stroke.
“Each element seemed simple on its own. The Dutchman’s genius lay in how to integrate these parts in order that they acted in a precisely synchronized order, sawing with each downward motion and advancing on every upward motion. This constituted a remarkably intelligent application of fundamental parts.”
Which brings us up to today’s puzzle. I’d like for you to reimagine one of the fundamental concepts underpinning Corneliszoon’s invention.
Circular to Vertical
Construct a machine that turns rotary motion into up-and-down action. You have these components only: A spinning wheel. Two pins. Two bars. A “sleeve”, which is a cylinder or sleeve into which one of the bars will fit perfectly. (Assume it is possible to put things on a base, so that the parts don’t collapse.)
I’ll be back at 5pm UK with the solution.
Meanwhile, NO SPOILERS. Rather, feel free to propose (non obvious) candidates for the world’s greatest creation.
