A machine for raising water, consisting of an endless rope or ropes passing over a pulley fixed at the place to which the water is to be raised, and under another pulley fixed below the surface of the water. The upper pulley being turned rapidly by a winch, motion is given to the rope, and the water rises up along with the ascending part of the rope, partly by the momentum it acquires when in motion, and partly by capillary attraction.
