In 1845 John Hick took his brother-in-law John Hargreaves Jr (1800–1874) into partnership followed by the younger brother William Hargreaves (1821–1889) in 1847. John Hargreaves Jr left the firm in April 1850 before buying Silwood Park in Berkshire. The following year B. Hick and Son exhibited engineering models and machinery at The Great Exhibition in Class VI. Manufacturing Machines and Tools, including a 6 horse power crank overhead engine and mill-gear driving Hibbert, Platt and Sons' cotton machinery and a 2 hp high-pressure oscillating engine driving a Ryder forging machine. Both engines were modelled in the Egyptian Style. The company received a Council Medal award for its mill gearing, radial drill mandrils and portable forges. The B. Hick & Son London office was at 1 New Broad Street in the City. One of the Great Exhibition models, a 1:10 scale 1840 double beam engine built in the Egyptian style for John Marshall's Temple Works in Leeds, is displayed at the Science Museum and considered to be the ultimate development of a Watt engine. A second model, apparently built by John Hick and probably shown at the Great Exhibition, is the open ended 3-cylinder A 2-2-2 locomotive on display at Bolton Museum. Bolton Museum holds the best collection of Egyptian cotton products outside the British Museum as a result of the company's strong exports, particularly to Egypt. Leeds Industrial Museum houses a Benjamin Hick and Son beam engine in the Egyptian style c.1845, used for hoisting machinery at the London Road warehouse of the Manchester, Sheffield and Lincolnshire Railway. Locomotive building continued until 1855, and in all some ninety to a hundred locomotives were produced; but they were a sideline for the company, which concentrated on marine and stationary engines, of which they made a large number. B. Hick and Son supplied engines for the paddle frigates Dom Afonso by Thomas Royden & Sons and Amazonas by the leading shipbuilder in Liverpool, Thomas Wilson & Co. also builders of the Royal William; the screw propelled Mediterranean steamers, Nile and Orontes and the SS Don Manuel built by Alexander Denny and Brothers of Dumbarton. The Brazilian Navy's Afonso rescued passengers from the Ocean Monarch in 1848 and took part in the Battle of The Tonelero Pass in 1851; the Amazonas participated in the Battle of Riachuelo in 1865. The company made blowing engines for furnaces and smelters, boilers, weighing machines, water wheels
