No matter how complex a machine can be, it can be break down into many individual components. Some of the components may be repeated --like the nuts, the bolts, the pulleys, the gears, the rollers. But some machines are unique by their design and structural function.
Each machine component is a manifestation of the human cleverness. I say human cleverness because ingenuity and smartness is not an attribute of any ethnic group or civilization. Most of the machine components we have today are just refinements of previous inventions from different regions of the world.
507 Mechanical Movements is a book about many of those machine components and parts. Of course, the accelerated advancement of technology has replaced many machine elements of the modern machinery by electronic and electromechanical devices. But no matter that, many of its 507 illustrations still describe many successful patents of the time. You lose nothing by taking a look at the engravings before applying for a patent at the Patent Office.
But Five Hundred And Seven Mechanical Movements is a also motivational book. For its many engravings, it is good introductory book for kids and youngsters.
