Player piano

In 1881, a patent was issued for his invention of a piano player to John McTammany, Jr., of Cambridge, Mass. He had earlier filed a caveat on 7 Sep 1876. His patent descibed his "mechanical mucical instrument" as a mechanism for automatic playing of organs using narrow sheets of perforated flexible paper which governed the notes to be played. The first completely automatic piano player to be manufactured in the U.S. was the Angelus made in Feb 1897, which was patented by its inventor, Edward H. Leveaux, in England on 27 Feb 1879, and who was issued a U.S. patent on 4 Oct 1881 for an "apparatus for storing and transmitting motive power."
