The 1868 book is out of copyright. It has been reprinted many times so it is easy to find a hardcopy through a used book store, iin case you want one for your bookshelf.
Paper model automata that use some of the mechanisms in the book can be downloaded from this site:

Mr. Civitarese has added several models to his web site since my last visit, including a ship model, 3D realizations of Leonardo da Vinci designs, and a moon map. There is a huge amount of interesting material on this site, look for the small light "Older posts" at the extreme bottom left of the first web page.
