[edit] Removed Cite Request from Moncky claim
I removed the "fact" tag/cite request from the opening, regarding the origin of the term "Monkey Wrench" as being derived from a patent by Charles Moncky. The wiki-linked article on Monkey Wrench in the same sentence contains a cite that should be sufficient.
[edit] Use of adjustable spanners
I think the spanner should be used with the fixed jaw leading. The force applied to each jaw is the same (equal and opposite forces). However if the fixed jaw leads, then the load on the movable jaw will then be at its' base, which would minimise the bending stress on it. John I
[edit] Who makes it?
This wrench, according to the article, is manufactured by both Cooper Hand Tools and the Crescent Tool Company. So which is it? ---Ransom (--71.4.51.150 23:34, 22 January 2007 (UTC))
Cooper Tools makes crescent wrenchs. They must have bought Crescent Tool, although I can't find any reference to this on the internet. Many other companies make adjustable wrenchs, and in the USA "crescent wrench" is now used to refer to any adjustable wrench. John D. 199.64.0.252 20:08, 21 March 2007 (UTC)
[edit] Who invented the adjustable spanner
For the person who advised it is not sure who invented the adjustable spanner - I can definitely help you with the answer. My Grandfather "Robert Percy Stewart" of Sydney Australia invented the adjustable head of the shifting spanner. He was a brilliant man however uneducated and in 1917 (under advise from a Patent Attorney in Sydney) he caught steerage class on a steamship from Sydney to San Francisco and met with a Layer there who advised him the spanner had very limited use however "being the really nice guy he was" he would take the Patent off his hands for 20 pounds. With no money and little legal knoweldge my grandfather sold the Patent for the spanner to this unscrupulous solicitor and returned steerage class to Australia with about 5 pounds left to his name. We have the original patent for the spanner with all details including specifications and drawings and the original patent number thereon. I wish I had one dolar from each of the spanners my grandfather invented - I would indeed be a wealthy woman. If you would like any further info on this pelase email me at [address removed]- I would be only to happy to relate further info regarding my grandfathers inventions including the 'pipe cutter' which afater patenting this item he gave the patent away to a 'friend'
Have fun and happy inventing!
