Abstract: 2281. Scott, C. H. Feb. 5. Printing coated fabrics.-Relates to machines of the kind described in Specification No. 1214, A.D. 1898, [Abridgment Class Printing, Letterpress &c.] for printing floorcloth, linoleum, and the like. Fig. 3 shows a side elevation of part of a machine, and Fig. 4 a cross-section drawn to a larger scale than Fig. 3. Each printing-block a, with its carrier b, is supported by means of weighted levers 12 pivoted at 12<1> and connected to rods 14 which support the vertically-movable bearings of the carrier b. Beneath each bearing is arranged a coiled spring, the lower end of which rests upon a flange formed on a tubular holder provided with an adjusting tube or nut 19. Each block a is depressed, during printing operations, by means of bell-crank levers c pivoted to the machine framing at d and connected to a rod l, or pair of rods, which are reciprocated by means of cams m carried by the main shaft n, and arranged to act upon antifriction rollers o, on pivoted levers p connected to the rods l; or the rollers or other abutments may be mounted upon the levers c, or rods l. The return stroke of the rods l may be effected by springs q, but the shaft n may be provided with cams r, adapted to act against rollers s carried by the levers c, and thus cause the rods l to make their return stroke. Rods g are fitted upon trunnions h of each carrier b, and are provided with nuts f, against which bear the upper ends of the corresponding levers c. Any one of the blocks a can be thrown out of action by means of handlevers connected to the rods g, by arrangements of links and cranks. To enable any block a to be automatically thrown out of action, the corresponding hand-lever is connected to a sliding rod 1, which is periodically reciprocated by means of a cam 2<1>, connected by levers 2<a>, 2<d> to the rod 1. Upward movement of each block a is limited by means of stops 3, attached to the rods g, and adapted to strike against the lower sides of adjustable bent bars, or other stops, which are pivoted to the framing. Abutments or collars u are fixed to the rods g, and are raised by the bell-crank levers c, when the corresponding blocks have not, through any cause, made their return strokes. The colour boxes 10 are moved to and fro beneath the printing-blocks by rods 22 supported by rollers, and reciprocated by means of levers 23 and links 23', in the way described in Specification No. 1214, A.D. 1898, [Abridgment Class Printing, Letterpress &c.]. The levers 23 are mounted upon a rock-shaft 23<b> which also carries levers 23<a>, supporting antifriction rollers 28, and connected by rods 34 or other means to oscillating levers 31, carrying antifriction rollers 29. A cam 26, carried by a shaft 2, acts alternately upon the rollers 28, 29, and thereby causes the rods 22 to reciprocate. The colour boxes are mounted in supports bolted to slotted horizontal bars which are attached to the rods 22 by bolts or studs, encircled by coiled springs, the whole being adapted to allow the boxes to move horizontally to a slight extent, and also to be depressed.
