Are You Able to Solve This? That Overlooked Netherlands Invention Which Forged the Modern Globe

There are numerous candidates for the designation as “planet’s greatest invention.” The circular axle. The movable type. The combustion motor.

According to a recent publication, though, that honor belongs to a automated timber mill invented through Dutch inventor Cornelis Corneliszoon in 1593.

“Before automated cutting, constructing a simple merchant vessel necessitated approximately ten sawyers laboring over 90 days,” writes Jaime Dávila. “With wind-driven sawmills, an identical amount of cut lumber might be manufactured within seven days.”

Owing to this speedy mechanical saw, that turned logs into boards using virtually no human effort, Dutch builders were able to build ships faster than anyone else, an advantage that unleashed one hundred years of Dutch maritime, economic and cultural dominance across the continent and the globe.

The First True Industrial Machine

The inventor's lumber mill, contends Dávila, was “mankind’s first authentic factory machine.” A windmill rotated a wheel. A single part transformed its rotary movement to vertical action for the cutting blade. Another component changed the spinning movement into a sideway’s motion feeding the log toward the cutter. A geared mechanism shifted the log forward one precise increment per cycle.

“Each element seemed simple on its own. Corneliszoon’s brilliance lay in how to combine them in order that the machine acted within a precisely synchronized order, cutting with each downward motion while advancing on every return motion. This constituted an astonishingly intelligent application of fundamental components.”

Which brings us to the current puzzle. I’d like for you to reinvent a key the basic concepts behind Corneliszoon’s machine.

Circular to Vertical

Construct a mechanism which converts rotary motion to up-and-down action. You have these components exclusively: A rotating disc. Two pins. Two bars. A “sleeve”, that is a cylinder or housing through which one of the rods can slide perfectly. (Assume it is possible to put things on a base, so that the components don’t fall down.)

The solution returns at 5pm UK time with the solution.

In the interim, NO SPOILERS. Instead, feel free to propose (non obvious) contenders for the world’s most impactful invention.
