For those interested in these kind of mechanical things, Dover has republished some 19th and early 20th century public domain books that collected together mechanical movements. Some examples:

"507 Mechanical Movements: Mechanisms and Devices" by Henry T. Brown, from 1868: http://www.amazon.com/507-Mechanical-Movements-Mechanisms-De...

"1800 Mechanical Movements, Devices and Appliances" by Gardner D. Hiscox, first published in 1899. This is the 16th edition from 1921: http://www.amazon.com/Mechanical-Movements-Devices-Appliance...

There is also a website that has all the illustrations and text from the Brown book, and has added animated versions of many of them: http://507movements.com/about.html

For those who like printed books, Dover has an inexpensive edition of the underlying book [1].

There are many similar books, such as "A Victorian Handbook of Mechanical Movements" [2], and "1800 Mechanical Movements, Devices and Appliances" [3].
