WATER LIFTED BY COIL SPRING IN DEFIANCE O NATURE
> t opular Mechanics Defying the L"vs of Nature by liftitig water hiehei* than had been considered possible, a punip conslsting of *n eii(ileBs-ste?! noil spring mounteo on two pulleys has been produted, Tlae: Iree-turning wheel is at the bottom 01 the weil or other souree of water, "wliile the dri -e pulley, txu-nfcl by a small electric inotor, is at th> reservolr to wlileh ihe liquld is dellvered. As the sprlng paĀĀPK over the lower pulley, the curve causes th<* coil,s to spread sllghtly, jsCooping up water, whleh is lifted wlthin the hollow eoie of i the sprlng and thrown out at the top as the leoil ls spread by curvlng over the' uppei- pullcy. [ The inventor claLmf the pump will supply a lsteady stream to a receptacle 100 feet above tlie ! point at whieh the eoil picks up the liquid. [ In a test tower, a eoll spring one and oneihalf ineh.es in diameter delivered 37 gailons [of water per minute to an elevation of 27 feet.
