Screen-Plate Patents 487 dichromated colloid, printed under a matrix and then only one side was again coated, exposed and dyed up. Cut Screen-Plates.— Under this section are included those methods in which sections or slices of superimposed sheets of colored celluloid are made. O. N. Witt66 appears to have been the first to patent this method, and he pointed out the difficulties of avoiding black lines through the marginal superposition of ruled elements. This he proposed to overcome by superposing sheets of thin celluloid, colored suitably, with a cementing Fig. 126. Brasseur's U.S.P. 1,081,484 (Page 488). Fig. 127. Fifield's U.S.P. 990,247 (Page 488). solution of celluloid to make them adhere. A block was thus made of the requisite height to give the breadth of the desired screen. Or instead of this, sheets of greater thickness might be made and rolled out to the requisite thickness as in the manufacture of ivory celluloid. The use of gelatin sheets in the same way was suggested. This patent was never completed, but Witt had proved by actual experiment that the idea was feasible, and the patent was abandoned on May 8, 1899, in consequence of non-payment of fees.
