Watt's improved Newcomen engine
Watt's improved Newcomen engine. Computer artwork of James Watt's improved version of Thomas Newcomen's steam engine. The Newcomen atmospheric engine (patented 1705) was the first true steam engine. It had a 'walking beam' pivoted arm (upper left) to transfer power between the piston (at right end of arm) and the 'rod' (chain at left end of arm),and utilised a boiler (bottom right) to provide the steam. Watt's version (in May 1765) caused the steam to condense in a separate chamber (condenser) apart from the piston. This helped to maintain the temperature of the cylinder at the same temperature as the injected steam (by surrounding it with a steam jacket ),and meant that very little heat was absorbed into the cylinder itself on each cycle.
