Caird & Company

Caird & Company was a Scottish shipbuilding and engineering firm based in Greenock. The company was established in 1828 by John Caird when he received an order to re-engine Clyde paddle-tugs.^[1]

John's relative James Tennant Caird joined the company in 1831, and after leaving to work for Randolph, Elder & Co in Glasgow, rejoined the family business for good in 1838.

A year after the death of Robert Caird, the company was sold to Harland & Wolff Ltd in 1916 for £432,493. The firm continued trading as a separate enterprise, with Arthur and Patrick Caird on the board, until 1922. The Arthur Street engine works was sold to John G. Kincaid & Company in 1919.

Ships fitted with engines by Caird & Co

In the early years Caird & Co were responsible for fitting (or re-fitting) steam engines in ships. An example of this is the Glasgow fitted with a side-lever engine by Caird & Co in 1828 for G & J Burns.^[2] This being an engine running on only 5psi steam pressure, as was common at the time (the steam condenser created a vacuum so the effective pressure acting on the piston was the difference between the boiler pressure and the condenser vacuum). Also in 1828 Caird & Co re-engined the paddle steamer Industry (built in 1814 by William Fyfe of Fairlie), replacing the original single cylinder engine rated at 10 hp with a Caird single cylinder engine rated at 14 hp.

In 1845 details and drawings of Caird engines fitted in four West India Mail-Packets were published,^[3] these being the "Clyde", "Tay", "Tweed" and "Teviot". These were also side-lever engines, with two cylinders of diameter of 74.5in and stroke of 90in, driving 30 ft paddle-wheels, running at 15rpm. These mail packets were operated by the Royal Mail Steam Packet Company. Collated records of ships built on the Clyde^[4] suggest that Caird contracted out the building of the wooden hulls for these mail packets.

The Clyde was built by Robert Duncan of Greenock and launched in Feb 1841, registered Dec 1841.
The Tay was built by Charles Wood of Dumbarton, launched in July 1841, registered Dec 1841.
The Tweed was built by Thomson & Speirs of Greenock, launched in Apr 1841, registered in Dec 1841.
The Teviot was built by Robert Duncan of Greenock, launched in Oct 1841, registered in Feb 1842.

Other ships fitted with engines by Caird include :

The steam tugs Hercules and Gulliver built by Robert Steele & Co of Greenock in 1820s
The paddle-steamer Liverpool built by Robert Steele & Co of Greenock 1830
The steam tug Samson built by William Denny of Dumbarton in 1819. Caird engine fitted 1831
The paddle-steamer Gazelle built by Murries & Clark of Greenock 1832
The paddle-steamer Dolphin built by James Lang of Dumbarton 1834
The paddle-steamer Eagle built by Robert Steele & Co of Greenock 1835
The paddle-steamer Unicorn built by Robert Steele & Co of Greenock 1836
The paddle-steamer Juno built by Robert Duncan of Greenock 1837
The paddle-steamer Achilles built by Robert Steels & Co, launched May 1839
The tug Conqueror built by Robert Duncan of Greenock 1840
The paddle-steamer Flambeau built by Robert Duncan of Greenock 1840

Following this Caird fitted engines to a significant number of screw-steamers built by other companies (i.e. propeller driven) particularly those built by Denny of Dumbarton up until 1851, and other ship builders until 1863.^[4]
