A type of scores of water-raising devicesby perpetual motion in the seventeenth andeighteenth centuries. The Archimedean screw seems to havehad a strong hold on the minds of perpetual-motion inventors. 949. PERPETUAL MOTION. Self-moving water power. An Archi-medean screw mounted with three waterwheels, by its revolution pumps waterwhich falls consecutively upon thewheels, and gives the power required toturn the screw. Seventeenth century. 950. PERPETUAL MOTION. Chain pump as known in water wheel which is expected through a system of gearing to operate a chain pump, which pump shouldraise the water necessary to propelthe wheel, and so on forever. It isprobably unnecessary to inform ourreaders that this fallacious principlehas been tried in various ways, andthat there are occasionally yet to befound those so unskilled in mechanicalscience, and incapable of seeing theradical error of the device, as to wastetheir substance in a repetition of thistime-honored
