Fig. 7 a sectional view given to illustrate the action of the coinbinedapparatus. When the wires We are electriied and material is passing down the channel H the following act-ion takes place. The best material is not attracted, the matter second in quality is' attracted gently by the wires 72 and Hung' from them on either side through the spaces H1.' The very worst material is attracted so violently by the wires that it rises above them and is then repcllcd into :he tin trays- H2. The discharge spouts of H2 and H can not be indicated in this drawing.
vHaving now described my said invention what I claim 'as new, and desire to secure by Letters Patent is:-
1. The method of purifying flour, grain; rice and like cereals, consist-ini:r in feeding the same in comniinnted condition in a series of shallow streams slightly separated from one another, below a super osed conductor charged with high tension e eetricity whereby the impurities in said cereals are lifted from saogssxq. l 8A The methoftof puriying Hour, greci-nr 5 rice and like cereals, consisting in feedmg the same 1n commmuted condltlon m a senes l l I I v of Shallo'w streams slightly separatedfiom 15 one another, below a'superposed conductor' charged u ith hightensin electricity whereby the impurities in said cereals are' lxfted from' said stra-ams and re elled so as to fall between the streams, su )stantielly as described. 20
