China Had First Complex Machines, BBC News
 









Excerpts: 
 

Consisted of two or more machines working together
 Contained a stylus suspended over a rotating turntable
 Created evenly spaced grooves on a jade ring
 
 


Craftsmen in ancient China were using complex machines to work jewellery long
before such devices are traditionally thought to have been invented.(...)
The machine that carved the grooves would have linked rotational and linear
motion, perhaps using a stylus suspended over a rotating turntable, says Dr Lu.

"The complex machine that created these spiral grooves may also be among the
ancestors of the crank in China... sculptures to have mechanised a variety of
agricultural processes such as milling and winnowing," (...).
