With financial help from his business associate Englishman Matthew Boulton, he had succeeded by 1778 in perfecting his steam engine, which incorporated a sequence of radical enhancements, notably the closing off of the higher a part of the cylinder thereby making the low-stress steam drive the highest of the piston as a substitute of the atmosphere; use of a steam jacket; and the celebrated separate steam condenser chamber. The blowing cylinder for blast furnaces was introduced in 1760 and the primary blowing cylinder manufactured from cast iron is believed to be the one used at Carrington in 1768 that was designed by John Smeaton.
The decarburized iron, having the next melting level than solid iron, was raked into globs by the puddler. As cast iron became cheaper and broadly obtainable, it began being a structural material for bridges and buildings. 834 Cartwright's loom design had several flaws, probably the most serious being thread breakage.
