Rankin and Blackmore
Eagle Foundry, Baker Street, Greenock, were makers of steam engines for marine use.
1862 The Eagle Foundry of Johnstone and Leitch was bought by Daniel Rankin and Edward Blackmore, who quickly diversified from the manufacture of sugar making machinery into marine engines and boilers.
1887 New engines for Steam Yacht Myrtle illustrated and described at some length. 'The new engines are of the four-cylinder "disconnected" quadruple-expansion type working tandem on two cranks, patented by Messrs. John F. and Matthew Rankin, and the cylinders are 12 in., 17 in., 24 in., and 34 in. in diameter, all having a piston stroke of 24 in. Indeed these dimensions are almost identical with those of the engines of the Rionnag-na-Mara (which were illustrated in Engineering, April 9. 18S6, and of the success of which this orderwas an outcome), but with four cylinders instead of the six-cylinder three-crank arrangement,....'[1]
1889 See 1889 Shipbuilding Statistics for detail of the marine engines produced.
1890 Description and engraving of a 'disconnective' quadruple-expansion engine erected by Rankin and Blackmore, of Greenock, at the City Roller Mills, Limerick, belonging to James Bannatyne and Sons. The cylinders were 12 in., 16 in., 22 in., and 28 in. in diameter respectively, all having a piston stroke of 36 in. The valve gear was of the usual slide-valve pattern, for all the cylinders except the high-pressure one, which was fitted with Proell’s automatic expansion gear and governor, constructed by Thomas McCulloch and Sons, of Kilmarnock. 350 IHP at 75 rpm[2]
1914 Incorporated as a private company, Rankin and Blackmore Limited.
