DESCRIPTION. Our cradle bars for holding the plates are of steel for ground wood and all ordinary paper. For sulphate pulp — pure white or the more del- icate tints, they are of cast bronze or brass, grooved at both edges, thus giving two lives to the bars. One bolt at each corner holds plates and cradle in place. Applied to any screen, giving increased efficiency. -',;' - Our late improvcnients, which bear even date with the openinuc of the Pan-American, pat the " screwless " beyond the sugi^estions of any de- sired change by the best men of the art.
