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.
