Thomas Morton (8 October 1781 – 24 December 1832) was a Scottish shipwright and inventor. His most widely known invention is the patent slip.[1]
Biography
Morton was born in Leith in October 1781 and grew up to become a shipwright like his father, Hugh. After spending some time working for his father, Morton went on to form his own shipbuilding company in the borough which later became S. & H. Morton & Co.[1]
Unable to afford the installation of a dry dock in his Leith shipyards, Morton "resorted to the process of hauling up [ships] on greased ways".[2] As this method was both dangerous and time consuming in 1818 he invented and installed the first patent slip; a slipway with cradle to haul ships out of the water. He was granted a patent for the invention the following year.[2] In 1824 Morton sued John Barclay in Edinburgh for patent infringement after he had installed a similar design in the yards of his company, Stobcross, three years before. Barclay's version was described as a poor copy by fellow shipwright William Denny, and the court found in favour of Morton.[3]
Despite the popularity of the invention Morton did not profit from it for the first six years of the patent. A total of 45 slips were built (in Scotland, England, Ireland, Russia and the United States), earning the shipwright a total profit of £5737, before he applied for an extension to the patent in 1832. The extension was denied and instead a House of Commons select committee awarded Morton the sum of £2500.[1][2]
Morton died in December 1832 and is interred in South Leith church.[1] His company, S. & H. Morton & Co. continued operating.
