When did it get its patent and what was the original diagram?
The Electric Chair was being used for over 25 years without a patent. It was first used in 1890 and many other people adopted the killing chair but it wasn’t a registered invention until 1915. The exact date was Dec. 14, 1915 which once again shows that for over 20 years the electric chair was being used with no official government recognition. Well then it wasn’t against the law to use that kind of device now and days that chair would have needed government approval before being used.
5. How has the electric chair changed over the years?
The electric chair hasn’t really changed much over the years. Well the way the chair has been changed from round to square is one of the only changes. The chair has had no real needs for changes, so why change it? Well minor changes have been made to the voltage settings among other things such as chair size, strap width, etc., the chair has stayed its relative self for over 120
