Late eighteenth–early nineteenth centuries
Steam engines and working lives
Powering factories also changed working hours and children’s lives.
Turning improvement into usable power
Steam engines predated Watt. Repairing a model in 1763 prompted investigation of wasteful fuel use. At Boulton’s works, Old Bess pumped water in 1777 to address inadequate water power. Steam initially also supplemented existing equipment rather than instantly replacing it.
Factory systems and workers
An engine purchase alone did not power a factory. Size, local materials, installation and supervision mattered. Boulton and Watt’s multiyear payments spread costs. Design, site work, finance and contracts brought equipment into routine production.
Changing production and regulation
Efficiency did not guarantee safer work or shorter hours. The 1833 Factory Act regulated children in covered factories but excluded mines. Restrictions on women and young children underground followed in 1842. Protecting workers required institutions specific to different jobs.
Before and after

What supports the account?
Watt and Boulton needed design, on-site assembly and financing. An idea alone could not sustain factory operation.
Steam-engine improvements, Old Bess in 1777 and constraints of water power. Child labor, the Factory Act of 1833 and its exclusion of mines.
It cannot be explained as one inventor’s work alone.
Children’s contributions to family income did not ensure safe work. Hours and accidents complicate claims of automatic improvement.

One testimony cannot establish conditions in every factory.
