Lime BoU.—In this operation, which Is also known as bowkine(Lter. beuchen), the pieces are first run through milk of limecontained in an ordinary washing machine and of such a strength Besides being used for cotton goods, plate singeing is also em-ployed for certain classes of worsted goods (alpacas, bunting, &c.),and tor most union goods (cotton warp and worsted weft). A machine working on this principle has been constructed by!<. Binder, and the makers of the machine (Messrs Mather & Piatt,) claim that it does better service than the machines constructedon the older Fig. 3.—Gas Singeing Apparatus. 52 BLEACHING that they take up about 4 % of theu- weight of lime (CaO). Theyare then run over winches and guided through smooth porcelainrings ( pot-eyes ) into the kier, where they are evenly packed byboys who enter the vessel through the manhole at the top. It isof the greatest importance that the goods should be evenly packed,for, if channels or loosely-packed places are left, the liquor circulatingthrough the kier, when boiling is subsequently in progress, willfollow the line of least resistance, and the result is an uneven treat-ment. Of the numerous forms of kier in use, the injector kier isthe one most generally adopted. This consists of an egg-endedcylindrical vessel constructed of stout boiler plate and shown insectional elevation in fig. 4. The kier is from 10 to 12 ft. in heightand from 6 to 7 ft. in diameter, and stands on three iron legs rivetedto the
