Abstract: 17,169. Jensen, P., [Maemecke, J.]. Aug. 2. Printing yarns.-Relates to machines for printing yarn for carpets, plush or pile goods for upholstery, &c., and consists of improvements in the machine described in Specification No. 17,873, A.D 1900, whereby the printing of the different colours is effected during one passage of the printing-carriage through the machine. Fig. 1 shows a diagrammatic side view of the machine, and Fig. 3 the printing- carriage. The stretched yarn 2 lies on rods 3, the distance a part of which is equal to double the length of the pile of the fabric, and is printed by colouring-rollers &c. in a printing-carriage 1 controlled by a jacquard machine 12. The carriage is moved intermittently along the machine by an endless band 6 driven by gearing and passing over pulleys 5, and round a pulley 7 in the carriage. The pulley 7 is geared to a pin-wheel 117 cooperating with a notched disc 119 after the manner of the stop mechanism in watches, and the intermittent movements of the notched disc are communicated to the carriage by a wheel 9 in gear with a rack 8 on the framing. There are a series of printing-devices 126, 127 one for each colour, placed side by side in the carriage, and each is controlled by a row of tumblers or stops 10, the stops of each row being actuated by a row of holes in the jacquard cards. In Fig. 3, six rows of tumblers a, b, c, d, e,f are shown, corresponding with the six colour-printing devices shown in Fig. 1. When a tumbler 10 is actuated, it depresses a lever 14 in the carriage 1. Each printing-device consists of a perforated roller 126 moved to and fro over the yarn 129 and over a bar 128 which, during the movement of the roller, is lifted out of its colour box 127. The roller 126 is carried by an arm 143 pivoted to an arm 144 pivoted at 141. On the arms 144 are pins 142, over which the ends 140 of bars 139 normally reciprocate. The bars 139 are pivoted to arms 138 on a shaft 136 rocked by an arm 137 having a roller 135 engaging a cam 133 on a shaft 132 geared by bevelwheels 130, 131 to the shaft 115 of the pin-wheel 117. On the bars 139 are pivoted hooks 145 connected by cords to the levers 14, and, when a lever 14 is depressed, the corresponding hook 145 falls into engagement with the stud 142, and the printing-roller 126 of that printing-device is reciprocated. The bars 128 are carried by arms 156 operated by arms 155 connected to rods 153 having hooks for engaging pins 152 on arms 151 of a shaft 150 rocked by an arm 149, rod 148, and arm 147 having a roller engaging a cam 146 on the shaft 132. The rods 153 are connected by cords to the levers 14. The downward movement of the roller 126, when the bar 128 moves down, is limited by a bar 168 engaging the roller 169. The depressed lever 14 is held during each printing operation, and is then released by a cam-operated bar and returned to normal position by a spring. The return movement of the carriage 1 is effected by operating a lever 123, which disengages the gearing from the shaft 115 and engages gearing which drives the wheel 9 continuously in the opposite direction. A clutch 124 may be operated to disengage the notched disc 119 during the return movement of the carriage.
