Atlas Works, Great Bridgewater Street, Manchester,
and later at Glasgow.
Atlas Works was among the largest and most productive mechanical engineering factories in the kingdom.
1842 Thomas Sharp died.
1853 Description of the works.
1868. Approximately 1600 men employed. 
1888 Production transferred to Glasgow when Sharp, Stewart and Co moved there. 'The Engineer' reported on the sale of unwanted equipment. This included rope-driven travelling cranes made by Sampson Moore - one rated at 30 tons with 21 ft 1-in span, one 35-ton, 41 ft 2" span, and one 30-ton 21 ft 6" span yard crane. Most of the named machine tools in the sale were made by Sharp, Stewart (the best ones presumably having gone to Glasgow). The only other named machine tool makers were W Collier (planer), Robinson of Preston (bending rolls), and a pillar drill by James Little & Co of Manchester.
No trace of the Atlas Works in Manchester remains. The eastern end of the site is now occupied by a large terracotta-faced building, constructed in 1896-98 for Tootal Broadhurst Lee Co. By coincidence - or perhaps not - Atlas-like figures are incorporated (see photo).
