Warner Hydraulic Ram 1889

  • Warner hydraulic ram (plus other rams and hydrostat).
  • Robert Warner & Co.
  • Hydraulic rams require no external source of power such as an engine or motor.
  • They operate due to the inertia of the water flowing towards them.
  • With a reasonably good head, a hydraulic ram can achieve an efficiency of some 12%.
  • They are used extensively in the developing world and can still be found operating in rural Britain.
  • The precursor of the ram was the pulsation engine of 1772 developed by John Whitehurst of Cheshire, but the first self-acting ram was invented by the Frenchman Joseph Mongolfier (of hot-air balloon fame) in 1796, with his friend Matthew Boulton taking out the British patent the same year on his behalf.
  • The designs and patents were bought out by Josiah Easton of Somerset in 1820.
  • In this summary lie the names of two of the key people who developed British engineering in the 19th century.
  • The example on display was installed at Tedstone Court in Herefordshire to provide water for house and farm.
