The Greatest Mechanical invention

[NJHParticipant @njh]

Sorry Guys – you misunderstand me. I was only refering to an increasingly acrimonious exchange between a couple of members which has nothing to do with advancing this interesting thread. I feel it better that exchange be continued, if necessary, in private.

Meanwhile back at the thread…..

Given fire is out of the running .

I have to stick with the wedge or inclined plane..as most basic mechanism

.thus knives, axes, screw threads, gears, sextants( octants) , clocks…………

Although the pulley ( block and tackle) is pretty basic too..

And the antikethera mech.

( and other "copies" extant in Roman Rome) might have been made using dividing machines although these were never found ( cut one screw thread and one wheel and thus make another ( more accurate and "finer&quot)….. and the "joy" of bronze was its value so when the mech. was no longer recongised ,as of value the metal would have been recycled.. so only "LOST" examples would remain.

While fire is ineligable I am somewhat appreciative of the enclosed fire or 'stove' today. Also VPN which allows me to work from home in front of the stove.

Heres one last go at it, its the, 'Cantilever stick' that is put over a fire to hang stuff to cook or roast !

The Chinese Windlass is even simpler and can lift huge weights using a lever, one drum and one pulley. Add a simple ratchet and you have a non reversible system.

Where will this topic go next I wonder?

Since it started it has covered many different areas and been round the houses twice! even Graham now has drifted off his original question which I recall was him wondering what the 'The most valuable mechanical invention' was.

I am pleased that Graham has a nice ornate pair (of dividers) but surely they are not in the running to be the definitive answer to the original question?

For what it's worth (0.5p?) I think the variety of our opinions reflects the evolutionary way in which things mechanical have progressed over the centuries/millennia, making it difficult to point to any single invention or advance as being The Great Leap Forward. For almost every development which is postulated, it seems possible to say thet it would not have happened without some previous invention or discovery, until you get back to things like smelting bronze and iron. But even then, the first bronzefounders may have used flint tools to get their firewood.

How about a hole in the ground…

Useful for many things, getting under the car, standing Stonehenge stones upright, disposing of bodies, hiding treasure…

Dividers, used by Navigators to, 'Step' across a chart, or profiling the shape in a casting box. Useful for finding the center of something. Possibly scribing parallel lines down a piece of metal from one edge.

Charts are not linear and the scale down the side is used to set the dividers to step the distance at that latitude.

The invention of a sewage system was a gradual development over thousonds of years demanded by a growing problem facilitated by a growing population. The same could be said of the decreasing water use of the flushing toilet.

I still front the bow and arrow as an example that needs real inginuety and a real grasp of mechanical principles. The atlatl and spear throwing devices is all decreasing the accuracy of the spear, which is not spectacular anyway. If you have spent a few hour sneaking up on a pray, you would want to hit it with the first shot. If it is hurt, it can be folowed to the end, no matter how far.

In my opinion the bow and arrow is the greatest LEAP in mechanical development in human history.

If you look at the spear and atlatl that came after it it (did they?). they are just extencions to what was already known, but the bow and arrow needed a genuine understanding of mechanical priciples which is unsurpassed even in modern history. Considering that they had almost nothing to build upon, this, IMO is the greatest mechanical LEAP of invention in human history.

I couldn't find a PDF copy of the 'Scientific American' article refererenced herein;

but, more than thirty years on, I remember it vividly.

The infamous "Protect and Survive" propaganda was ludicrous by comparison.

Sadly, though they are the greatest spur to development. Aircraft and lorries during the first world war, jet engines and atomic weapons in the 2nd (from nothing to bang in 3 years). Seems to be human nature, a lot more effort has gone into swords than ploughshares.

So today it was announced that two cold war missile silos have been given British heritage status, and are now listed builings in the sense that they are important to our history !

So, lets propose the Rocket as it has lifted the human race into space and out of this world !

Hi Graham

I believe It was Eli Whitney not Colt who was the first to standardise parts in the manufacture of firearms (Muskets). also he is credited with the invention of the cotton gin.

He was certainly an early adopter of the milling machine, (possibly the inventor).

Cheers

Whilst I abhor weapons the developement of the firearm has been interesting purely from an engineering point of view, Samuel Colt did give us interchangeability of parts.

Hi Gray,

I hate to differ but it was Maudslay and Brunel who gave us interchangeability with their block making machinery for the Royal Navy at Portsmouth in 1803, The production line was set up and the machines so accurate that any pulley would fit any block from the same range.. Maudslay also saw the advantages of interchangeable nuts and bolts later taken up by one of his co-workers, Mr Whitworth.

Best regards

The reductio ad absurdunm argument advance below supports my suggestion of the flint blade. More correctly flint or obsidian tools which required a degree of skill to make and use, but would have transformed the lives of those who had them.

As a myopic, I doubly appreciate these wee things as the invention of simple tools suddenly made short-sighted folk valuable to the community.

I still vote for what was probably the first tool which had to be devised rather than found, The Hammer. Read the history of the inventor, New-Fist-Hammer-Maker here

Hi, I also dislike any type of firearms, or any other types weapons that are the subject of conflict. It is however, ironic that they are in fact a most important invention to a lot of peoples lives as well as being fatal to many others. As an example, apart from all the battles and wars that have happened in the distant past, my own life and that of my siblings would in all probability not have happened if not for both of the two world wars. Firstly because if the first world war did not happen, it is unlikely that my mother would have been born, and secondly, if the second world war did not happen my parents would probably not have meet when they did or even maybe not at all. This kind of scenario is likely to be the same for many post war births.

I still would not put any weapons, no matter how sophisticated they are as the greatest invention. The first clock of good accuracy and repeatability must be a contender, as it was likely to be one of the things that have made the logistics of our lives so efficient as it has become.

Regards Nick.

Hi All

Brunel Born 1806 only started work within a year of Eli Whitney' death (January 1825) so I guess that gives the discovery (Or at least rediscovery and improvement of previous work) to Whitney.

Maudlsley overlaps a bit so there is room for conjecture there.

I have been to the Whitney museum and have seen first hand some of the jigs and fixtures he made. By modern standards pretty rough however well advanced for his time.

Cheers

Not too far off-topic, I hope …

The new series on BBC4 "Order and Disorder" by Jim Al-Khalili, is superb.

If you missed the first part; catch it on iPlayer.

A number of years back there where articals in ME on the development of machinetools, including the milling machine, and lathe. Also articals on block making machinery, and stock making machinery,the latter imported from the USA in the 19th cent, and used up untill the 1950s (I think), used by Enfield, but theres others who know more about these.
