James Simpson and Company

Simpson and Thompson was created in 1825 as a partnership between James Simpson, engineer of the Chelsea Waterworks, and George Thompson, engine maker.
The partnership was dissolved in 1836.
James Simpson founded James Simpson & Co., a manufacturer of steam engines and pumps, and made several improvements to the design of these machines.

In 1857 James Simpson, Junior, joined the company, which made pumping equipment, particularly

The British pump suppliers did not have the capacity to deliver the pumps fast enough. James Simpson & Co. learned of the Worthington company because of this order, and on 13 December 1885 signed an agreement with the Worthington Pumping Engine Company under which they gained exclusive manufacturing rights for Worthington pumps in Britain.
The pumps would be sold in the English and Colonial markets.
The company delivered a Worthington pumping engine for Bournemouth Waterworks in 1889, and a Direct-Acting Pump for the Hammersmith Station of London's Metropolitan Water Board in 1890.

said Worthington pumping engines were almost entirely replacing beam engines and other types of fly-wheel engine. The engines were more powerful and consumed less coal for the same amount of work.
James Simpson and Co were the sole licensees for this type of engine.
On 11 July 1892 James Simpson and Co became incorporated as a public company. In 1895 James Simpson and Co were described as crane, pump, iron girder and iron tank manufacturers, hot water apparatus makers, ironfounders, with headquarters at 101 Grosvenor Rd, London SW.

In 1910 the company's registered office was 153 Queen Victoria St, London, while the works were at Newark.
In 1917 the company name was changed to Worthington Simpson.
American associates had gained control of the company.
Alfred Telford Simpson, who had been chairman of James Simpson & Co., continued as chairman of Worthington-Simpson until his death in 1928.
Worthington-Simpson was one of the leaders in manufacture of engines and pumps for the remainder of the 20th century.

Worthington-Simpson built a horizontal engine with gear drive for Eastbury Station of the Watford Waterworks in 1920.
The company designed and built two triple expansion steam engines for the
Kempton Park Water Works.
