Metcalfe family

James Metcalfe invented the exhaust steam injector and developed it with the financial support of David Davies and Edward Hamer. A major source of information is Richard Metcalfe's Davies & Metcalfe Ltd, but this book suffers from a lack of organization as a biography, and it is difficult to trace the history of James Metcalfe which becomes lost in a welter of detail about other Metcalfes some of whom shared the same Christian name. James Metcalfe, the key figure, was born at Morda (near Oswestry) in 1847 and died at the family home at Sychtyn near Oswestry on 12 April 1920. He was apprenticed at Sharp Stewart, then worked for the company until 1867 when he joined the Manchester & Milford Railway at Aberystwyth as locomotive foreman. Metcalfe had been involved with the design and manufacture of injectors whilst at Sharp Stewart who were the sole British manufacturers of the Giffard injector. At Aberystwyth he developed, and patented, the exhaust steam injector, with assistance from his father (Richard Metcalfe, b. 1824), and with the financial assistance of Edward Hamer, General Manager of the Manchester & Milford Railway, and David Davies, railway and colliery magnate, and his son, Edward Davies.

The Patent Exhaust Steam Injector Company was established in Aberystwyth in April 1878 and manufacture originally took place at the Rheidol Foundry.
