When James Watt first heard about the new tubular
boiler he publicly claimed that Trevithick should be hanged for creating
something so lethal. And it was lethal – mainly because the quality of
metal available at the time, and the rivets used to bolt the plates together, were simply not strong enough to withstand
the enormous pressures. Trevithick
also invented a safety valve for the boiler – after he left one of his
engines on a cart outside an inn where he remained drinking for several
hours, and it blew up.
High pressure steam cut coal consumption by four
fifths, which was a huge financial saving. So after the new Cornish high-pressure steam boiler proved to be successful, Boulton & Watt registered
patents which, for over 40 years, made further development by any other engineers impossible. Any attempts to work round these provoked immediate threats of litigation.
Richard Trevithick’s fertile mind meant he
invariably worked on several inventions at the same time. This made him
hard to pin down to a particular project. He had a quick temper, fell out with his patrons, was
invariably short of money, and hopeless at business.
He married Jane Harvey whose father had established
an iron foundry and engineering works in Hayle. All too aware of
Richard Trevithick’s poor money management, and anxious that his sister
did not suffer, Jane’s brother installed her as manager of his hotel, The White Hart,
which she ran while raising six children. This income sustained the
family during the sixteen years that Trevithick was in South America. He
walked a thousand miles from one side of the continent to the other,
maintaining engines and boilers built in Cornwall and sent out to
the mines in Chile, Peru and Mexico.
Despite his many remarkable inventions Richard died a pauper. But at the ‘Trevithick Day’ celebrations in Camborne, a replica of
his ‘Puffing Devil,’ the world’s first successful self-propelled vehicle, reminded the crowds of the achievements of this remarkable
Cornishman.

Poor Trevithick is still struggling for recognition - Locomotion: Dan Snow's History of Railways started by looking at the birth of steam pumps and steam engines but my recollection is that he didn't even mention Trevithick, let alone give him the credit he deserves. I kept yelling his name at the TV but to no avail...
I feel sorry for poor Jane Trevithick, left to bring up six children on her own and run an inn, to boot!
Helena, it's so frustrating when someone like Dan Snow, whose audience will assume what he says to be factual and accurate, gets it wrong.
To be honest, Elizabeth, Richard was such a disruptive and erratic influence on everyone when he was at home, her life was perhaps a lot less fraught during his absence even with the responsibility of six children and the inn!
