Over five
hundred simple mechanical movements from America's first one hundred
years of the Industrial Revolution. For those who share an interest
in mechanical things, this book is addictive. Through the use
of simplified, concise drawings, here are 507 of the small components
which make up complex machinery in areas as diverse as C.R. Otis's
safety stop for the elevator, Pickering's governor for a steam
engine, Arnold's escapement for watches, compound parallel
rules, piston rod guides, the grasshopper beam engine and a self-recording
level for surveyors. The list goes on and on in fascinating variety,
with each movement explained and illustrated.
