Talk:Combination lock
From Wikipedia, the free encyclopedia
[edit] Hmm. What about Al-Jazari?
The article Al-Jazari states the following:
- "Al-Jazari described fifty mechanical devices in six different categories, including water clocks (one of his famous clocks was reconstructed successfully at the London Science Museum in 1976), combination locks, hand washing device, machines for raising water, double acting pumps with suction pipes and the use of a crank shaft in a machine, accurate calibration of orifices, lamination of timber to reduce warping, static balancing of wheels, use of paper models to establish a design, casting of metals in closed mould boxes with green sand, and more." - emphasis added by me.
I have no idea about the veracity of the above, but if it is accurate the current article on combination lock should reflect that. I make it Al-Jazari predates Cardano by a few centuries. -- Cimon Avaro; on a pogostick. 21:22, 4 April 2007 (UTC)
[edit] Joseph Loch
A Google search indicates that Joseph Loch filed a patent for a "permutation-lock" in 1878, not 1862 as cited in the text. In addition, there is no evidence I could find of a patent infringement dispute. Shalom (Hello • Peace) 20:07, 14 February 2008 (UTC)
