I found these almost by accident in my travels through the tubes that make up the interweb. As I was trying to learn more about clocks and clockmaking I found a few books digitzed by google that are now in the public domain, so I thought I would share. The gear book was the most helpful to me. I hope these can help someone else as well.
The biggest help with drawing gears was this one:
American machinist gear book By Charles Hays Logue, Reginald TrautscholdThe next one has a chapter (ch. 10) on gear trains:
Elements of mechanism By Peter Schwamb, Allyne Litchfield MerrillAnd the last one I found is self explanitory:
Watch and clock making By David Glasgow
