Watt moves to Birmingham to develop his steam engine with Matthew Boulton.

Watt and Matthew Boulton begin commercial production of improved steam engines.

Receives an extended steam-engine patent, allowing Boulton and Watt to commercialise improved engines.

A fundamental change in working principles In close collaboration with Englishman Matthew Boulton, succeeded in perfecting his steam engine, which incorporated a series of radical improvements, notably the closing off of the upper part of the cylinder thereby making the low pressure steam drive the top of the piston instead of the atmosphere, use of a steam jacket and the celebrated separate steam condenser chamber

James watt patents a double-acting rotary steam engine

The Watt steam engine had been fully developed into a double-acting rotative type, which meant that it could be used to directly drive the rotary machinery of a factory or mill

1st Boulton & Watt steam engines are used for spinning at a factory in Nottinghamshire

Supports the Soho Foundry as Birmingham becomes a centre of steam-engine production.

James Watt dies at Heathfield in Handsworth after a celebrated engineering career.
