Dewrance & Co. Ltd was a manufacturer of engine and boiler accessories, such as pumps and gauges.

History

It was established in London in 1835 as a partnership by Joseph Woods, with John Dewrance. It was involved in the building of the locomotive Lion in 1838 for the Liverpool and Manchester Railway.[1] In 1844 after Wood's death the firm became a company specialising in manufacturing engine and boiler accessories. It produced a brass pressure gauge for Lloyd's Register of shipping to pressure-test ships' boilers before insuring them.[2] Such gauges have become collectable.[3] A pair are on display at the Internal Fire – Museum of Power.[4]

Dewrance died in 1861 and left the business to his son.[5] The firm's introduction of the groove-packed plug cock in 1875 was a major innovation because it made steam safety valves easier to operate.[6] Sir John Dewrance,[7] who was married to the granddaughter of Richard Trevithick took over the business in 1879.[8] In 1937 after Dewrance's death it became a wholly owned subsidiary of Babcock & Wilcox Ltd.[8]

In 1961 it had 2,000 employees.[5]

The firm was sold by Dresser Industries in 1998 to Tyco International. It was then operating from Skelmersdale.[9]

John Dewrance

John Dewrance conducted experiments on the distribution of heat in steam boilers.[10] There are claims he was responsible for the construction of George Stephenson’s locomotive the Rocket and for supporting it at the Rainhill trials.[9][lower-alpha 1] He was appointed Locomotive Superintendent of the Liverpool and Manchester Railway from 1840 to 1844 during which time his 2-2-2 designs at the Edge Hil workshops were noted for their neatness.[11]

In October 1845 he entered the employ of the Great Southern and Western Railway of Ireland and was selected from three candidates as Locomotive Superintendent in March 1847 at a salary of £300 pera anuum with housing assistance.[lower-alpha 2] He was immediately seconded to locomotive manufacturer William Fairbairn & Sons, Millwall, London to gain experience. Following a review in October 1947 his services were dispensed with due to claim his remuneration was inappropriately high for his abilities.[13] He was then appointed Locomotive Superintendent by the rival Midland Great Western Railway (MGWR) of Ireland, again for £300 per annum with a house in Cabra Road, Dublin.[14] Following the decision of the MGWR director's to let the operation of the line Dewrance was released with three months salary.[14]

Dewrance died in 1861 and left the business to his son.[15][5]

Sir John Dewrance

Sir John Dewrance, who was educated at Charterhouse and then at King's College London before marrying the granddaughter of Richard Trevithick, took over the business in 1879.[7][16][8] He took out 114 patents relating to steam fittings and boiler mountings.[17] He was involved with the Primrose League. In 1899 he became chairman of Babcock & Wilcox Ltd.[18] From 1920 to 1926 he was the President of the Engineering Employers’ Federation.[19]

Dewrance died in 1937 with the firm becoming a wholly owned subsidiary of Babcock & Wilcox Ltd.[8][20]

The Sir John Dewrance prize is awarded to the two best mechanical engineering students each year at City University.[21]

Recognition

One of the GWR Hawthorn Class locomotives built by Slaughter, Grüning and Company was named after the company in 1865.[22] British Empire Medals were awarded to Arthur Edgar Caswallon Evans, a Brass Turner in the 1946 New Year Honours,[23][24] to Jasper Sidney Jeal, a Centre Lathe Turner in the 1953 Coronation Honours[25] and to Maud Unwin, a Fettler, in the 1956 New Year Honours.[26] James McWaters Storey, the Managing Director, was appointed Commander of the Order of the British Empire in the 1959 New Year Honours.[27]

The firm's archives are held in the British National Archives.[28]

Notes

  1. ↑ The single current source with the Rocket claim may not be independent,[9] and some may claim this was unlikely. If Dewrance could be linked with George Stephenson's firm then association with the Rocket might be entirely possible and his positioned at the L&MR to aid servicing of Stephenson's locomotives would then be very reasonable but there is no current sourcing to support this.
  2. ↑ The 1974 work Murray and MacNeill claim Dewrance was Locomotive Superintendent or equivalent since 1844.[12]
