Old-Timey Patent: Apparatus for Recording and Reproducing Speech, 1904

Shown here a patent for a magnetic wire recorder by Elias E. Ries. There are quite a few patents for devices like this, but I just dig the way this one looks. I love the drawings in old-timey patents, and they way they can convey motion and depth with nothing but linework. The other reason I love these things: they represent our heritage of invention and innovation in America.
