Outdoor Screws

What it really came down to was a few basic designs that used a huge beam that was pulled down to squish the fruit now to you this idea may seem impossibly out of fashion by a few thousand years but if you're like me you probably have one of these fruit presses in your kitchen too this is just a mini version of an idea thousands of years old and one of the first and most important simple machines ever made eventually someone made a huge leap by using a screw vertically through the end of the beam and anchoring it with a giant rock now you could use pole to turn the screws which tried to pick up the rock but really had the practical effect of bringing the lever down but then there was another leap in a new different press which would Metal Corner Brackets eventually have an incredibly profound impact far far beyond fruit pressing this new press got rid of almost everything and put the screw right on top of the fruit pressing on boards this press had the advantage of being small easier and cheaper to build and still highly effective.

Now a single person can easily pull a lever and exert a tremendous amount of force downwards on the simple cheap machine that's also very productive or alternately you could make a larger version and employ a few people or animals to press a lot of fruit really profitably and they were used until relatively modern times but the importance of this style of the press doesn't end with olive oil and wine oh no it's way more important than that in the next episode in this series you'll see how this simple style of press and the pattern of this machine is something of a ticking time bomb when combined with a few other inventions roughly fifteen hundred years later it would help kick off a chain reaction that would impact millions of people or some of the best but also some of the most horrible things Outdoor Screws that will happen in western civilization really start to unfold and which we're still dealing with today.

But we're gonna save that for next time remember archimedes the guy who was the first to describe the water screw earlier he's probably the inventor of a completely different way to use a screw and something we generally now call a worm drive this simple but clever device combines a screw acting as a special gear and the worm wheel which is a gear of only slightly different from the brilliance of this cannot be understated as it allows for a great conversion of rotational distance to torque in a very compact and elegant way while also turning the direction of travel 90 degrees it takes one full turn of the endless screw to advance one tooth of the worm wheel this has a great advantage of a massive reduction by however many teeth you have in your gear to one with this idea and a few other tricks like the compound pulleys.
