The Industrial Revolution expanded Arbroath's economy and population. New housing appeared to house the influx of workers. Arbroath became known for jute and sailcloth production, with 34 mills with 1,400 looms producing over a million yards of osnaburg cloth and 450,000 yards of sailcloth in 1875. Arbroath is believed to have supplied the sails for "Cutty Sark". In 1867, the mills employed 4,620 people. Arbroath was also prominent in the making of shoes and lawnmowers; the local firm Alexander Shanks was founded in 1840 and based at Dens Iron Works, supplied mowers to the Old Course at St Andrews and the All England Lawn Tennis and Croquet Club. Shanks was taken over in the 1960s by another local firm, Giddings & Lewis-Fraser Ltd., which had evolved from the business of Douglas Fraser, established in 1832 and mainly concerned with manufacturing flax and canvas. In later 19th century the firm, by then Douglas Fraser & Sons, moved its focus onto machine manufacture, after the success of a braiding machine designed by Norman Fraser. The firm had interests in South America and India. In 1959 its firms were taken over by the US company Giddings & Lewis and renamed Giddings & Lewis-Fraser. Its headquarters were Wellgate Works, Arbroath.
