He was the inventor of an early steamlocomotive, the Sans Pareil. His design in 1827 used a steam blast-pipe in the chimney to draw the fire, and he is usually acknowledged as the inventor of this concept. However, Sir Goldsworthy Gurney claimed prior art, having used a similar steam blast as early as 1822. The steam blast was copied by Stephenson for his locomotive, the Rocket. According to another source (Brown, 1871), Stephenson used the steam blast already before 1815. Hackworth's locomotive was heavy and the steam engine failed during the Rainhill Trials in October 1829. The engine was however subsequently used on the Liverpool and Manchester Railway and can still be seen in action at the Timothy Hackworth Museum.
He also built, at Shildon in 1836, the first locomotive to run in Russia for the St Petersburg railway and in 1837 the Samson for the Albion Mines Railway in Nova Scotia, one of the first engines to run in Canada.

Hackworth was born in Wylam, Northumberland, on 22nd December 1786 and died in Shildon, Co Durham, on 7th July 1850.
Reluctantly Hackworth agreed, and thus supervised the construction of the first locomotives at this works: it was Hackworth who suggested coupling the wheels of S and D locomotives No 1 Locomotion and its three successors with outside rods and return cranks instead of chains.
Hackworth's next locomotive was the Wilberforce class 0-6-0 of which six were built in 1831-2.
He was the inventor of many early steam locomotives, including the Sans Pareil, which took part in the Rainhill Trials in 1829 Although Hackworth's locomotive was heavy, it was allowed to take part, but failed when a cylinder cracked.
His design in 1827 for the Royal George used a steam blastpipe in the chimney to draw the fire, and he is usually acknowledged as the inventor of this concept.
