Motion is commu-nicated t<:• the disc by a belt upon the pulley P. The pump and pipesfirst being tilled with water, rapid motion is uiven to the disc K. whenthe centrifugal force imparted to the water between the wings causes itt:» flow through the passages § and E. to the outlet e: a vacuum beingthereby created between the wings, which causes the water to risethrough the pipe B. to keep up the CENTRIFUGAL PUMPS TURBINE ELEVATOR. 189 By means of the spiral passages around the boss L, the water fromthe suction-pipe is turned gradually from a direct forward course, anddelivered to the propelling wings in the line of their action$ thence,through the spiral passages g and E it is again, by an easy, gradualcurve, brought back to a straight course, upon reaching outlet e. Thewings on the disc K, passing beyond its outer edge, create and main-tain a vacuum between it and case D, and prevent sand, dirt, &c, fromcoming into contact with the shaft. The bearing UST is in like mannerprotected from dirt, enabling the pump constantly to discharge a largeproportion of sand, gravel, &c, without injury to any of its parts. Therebeing no valves in action, (the foot valve remaining open while the pumpis in motion, and used only to retain the charge when at rest,) and nowearing parts except the shaft in its bearings,
