Alan Day Posted April 29, 2009 Share Posted April 29, 2009 I have been reading the Wheatstone Patent 1844 and it clearly patents amongst other things the construction of a reed for use in a concertina. He patents at the same time the English System and the drawings are a remarkable likeness for those still produced today. I notice that George Jones Filed a Patent almost exactly Forty Years later for the Anglo German System. Does this mean that patents were only applicable for Forty Years? Charles Wheatstone was in fact updating his previous Patent 1829 for air blowing through a vibrating reed. This means that he also held the Patent rights for a Harmonium that uses exactly the same principle. Finally in amongst the Patent he refers to the Concertina for the first time and I quote " This musical Instrument as such has since been named the Concertina and is generally known by that designation". This would imply that The Concertina was being made long before 1844. So if Wheatstone held the Patent for the manufacturing principle of reed manufacture, how did the other manufacturers get around it ? Or was there a free for all in 1884? The patent can be read at Robert Gaskins site in full detail Al Quote Link to comment Share on other sites More sharing options...
