Abstract: 17,873. Hallensleben, O. Oct. 8. Printing yarns.-Relates to apparatus for printing, steaming, and washing yarns used in the manufacture of carpets, plush or pile fabrics, and the like. Fig. 6 shows a plan of the machine, Fig. 7 a transverse section, and Fig. 2 an elevation of the printing-carriage. In the framing 1 are two shafts 2, each carrying a set of parallel rods 3, spaced apart according to the points of the design. The yarn is stretched upon the rods 3 and is printed at the points required by printing-carriages C, which move along rails 4 to bring them into the various printing-positions. The printing-arrangements are in duplicate as shown, so that one side of the machine can be supplied with a batch of yarn while that on the other side is being printed. Each printing carriage, Fig. 2, has wheels running upon the rails 4 along which it is moved by a driving-band running over a pulley 7 on the carriage and over pulleys on the framing. At the end of the machine are two jacquard machines 12, one for each printing-carriage, and each provided with cards representing the various colours to be printed. Each card operates to set some of a series of stopping-levers 10 which operate to stop the carriage C in each position for that colour. The levers 10 operate through suitable mechanism to disengage a clutch 25 through which the carriagedriving gear 9 is driven from the shaft of the pulley 7. The gear 9 engages a rack 8 on the framing. When the clutch 25 is disengaged, a second clutch 26 is engaged to set the printing-mechanism in motion, to lay the colour on the yarn in a strip between two of the rods 3. The clutch 26 puts in motion a train of wheels, including mitre-wheels 27, by which a cam 28 having a nose 29 is rotated. The nose 29 normally engages a roller 31 on a lever 30, and when the gearing 27 &c. is started, the lever 30 is permitted to drop, thereby bringing the printing-rollers 57, and the supporting-rollers 60 into contact with the opposite sides of the yarn, and at the same time moving them along to print. The rollers 57 and 60 are mounted in arms 51, 59 pivoted on a slide 41 moving in guides in the carriage. The arm 51 is rocked by gear teeth 35, engaging teeth 34 on a lever 33 engaging a slot in the lever 30. The lower arm 59 is rocked by a rod 32. The slide 41 is moved by a lever 40 connected bv a rod 39 to the lever 30. At the end of the printing operation the clutch 26 is disengaged, and the clutch 25 engaged, and the nose 29 of the cam 28 raises and supports the lever 30 until the carriage is again stopped. A measured quantity of colour is supplied to the printing-rollers at each printing operation from a reservoir 46 on an upright 45 of the carriage. A cock 49 is opened at each printing operation to fill a smaller reservoir or receptacle 47, and at the end of each printing operation a cam 52 on the arm 51 operates a lever 53 to close the cock 49 and open a cock 50, so that the colour in the smaller receptacle 47 can flow into a receptacle 56. When the arm 51 is again lowered, the colour flows from the receptacle 56 over a perforated plate 58 above the rollers 57. Springs 61. press the rollers 59 upwards. The driving-mechanism for the carriage is so arranged that, when the carriage reaches the end of its forward movement, its motion is automatically reversed, and the carriage returned to its starting position, where it remains at rest until started by the operator. After the yarn has received all its colours the rods 3 are tilted, by cranks and gearing, so that the printed yarn falls on to a truck 83, by which it is run into a steaming-chamber 85 for fixing the colours. After steaming the carriage 83 is run back on to the rails 84, which are carried by supports 109 hung upon cords. The rails 84 and carriage 83 are then lowered into the washing-tank 96. The yarn is caught by a series of forks 102, and lifted from the carriage 83, so that the yarn and carriage are separately washed. The washing-forks 102 have a vibrating movement while the yarn is thereon.
