    hnpTO'De'^uents in the 3fctnufaGtuTe of Lint and Lint Landages, Tlie warp yarns or threads of which the lint or lint bandages are to he made are wound on a number of bobbins or on a beam and passed through a reed or comb, and between a pair of fluted or plain rollers, or rollers covered with cloth or other slightly yielding material, from which rollers the yarns or threads pass to the healds or harness of the 5 loom to he woven with weft into cloth in the same manner as linen and calico. After the cloth is woven instead of passing it over a breast beam and taking it up on a cloth beam, as in the ordinary linen or calico loom, I cause the cloth at from three to six inches from the last pick of weft to he received by a pair of plain fluted 10 or covered rollers, or by a single roller having spikes or covered with, wire card. In one arrangement the cloth passes from the rollers or roller behind a metal bar fixed to the front of the loom, and before a cranked rod, to which revolving motion is given by gearing in connection with the 15 crank or tappet shafts of the loom, and from the cranked rod the cloth passes between a horizontal linting knife having the ordinary to-and-fro motion and pause, and an uncovered or covered metal roller or plate acting as a cushion. The knife is pulled to or pressed against the cloth in contact with the cushion by india-rubber or other springs, and pushed 20 from the cloth and cushion by slotted or forked rods moved to and fro by eccentrics on a shaft driven by toothed wheels, the eccentrics being so adjusted that as the cranked rod revolves it shall raise the cloth at the time the knife is pressing the cloth against the cushion, and thus perform the operation of linting. The cloth and yarns are drawn through 25 the machine by the front fluted, covered, or plain rollers, or by the spiked roller, revolving motion being given to one of the rollers by means of toothed gearing turned by a ratchet wheel worked by a catch or ratchet on a rod moved up and down by a lever on the ordinary rocking shaft, or to and fro by the slay or batten ; and in order to draw the yarns and 30 deliver the cloth in even quantities elastic pads between the hearings of the rollers and regulating pressure screws are employed. % In another arrangement or modification I employ a vertical knife having a cushion below it and move the cloth to be tinted by a straight rod working vertically, the knife being moved one way by springs and 35 the other way by eccentrics and rods and instead of passing the warp yarns or threads between fluted or covered rollers at the back of the
