Mechanical Movements

     I have no idea what you can do with this site except amuse yourself. 507 Movements is an online edition of the classic technical reference Five Hundred and Seven Mechanical Movements by Henry T. Brown. This site contains the original illustrations and text from the 21st edition of the book, published in 1908. It also includes animated versions of the illustrations, and occasional notes by the webmaster.
