Speed ami Alex. Whitton, of WestSprinjifield, Mass., have invented a devicefor watermarking paper which, it is claim-ed, though making use of cylinders doesaway with the dandy roll. A pair of cy-linders in provided which have their loca-tion forward of the first one of the dryerdrums employed as part of or in conjunc-tion with paper machines so that the web which are \ertically movable to whichpressure in a downward direction is im-parted, and in conjunction with whichboxes are means whereby the downwardmovements of the lower boxes are limitedso that the co-operation cylinders them-selves are never brought to circumferen-tial contact, although in every revolutionof the upper cylinder its impression carry-. being drawn out from the wet end of themachine and becoming partially dry is sub-jected, while yet damp, to the paper mark-ing impression of one of a pair of cylind-ers which has one or more arc faced pro-jections extending from the circumferen-tial surface thereof provided on such arcface with impression forming surfaces,such cylinder being journaled in boxes ing projection or projections are broughtto pressure bearings against the peripheryof the lower cylinder or against the webof paper running thereover.
