Abstract: 23,902. Sulzbach, J. Oct. 29. Printing yarns.- Colours or dyes are evenly distributed upon yarns of silk, &c. and the surplus evenly removed in a machine which is also adapted for multi-colour. variegated, or shaded dyeing. Different colours, or tints of the same colour, are contained in a number of vessels, each provided with a distributor, and are applied serially and changed automatically, or any two can be alternated by means of a reversing-mechanism. The machine consists of three parts, namely, the dye application and surplus dye removal mechanism on a frame 20, Figs. 1 and 2, at one end, the bobbin winding-machine on a frame 200, Fig. 4, at the other end, and a steam chest 75 mounted on beams 220 which connect the two frames. Power is supplied through a belt 33 and fast and loose pulleys 31 on a driving-shaft 34 splined to take a friction wheel 35 reciprocated against the face of a friction disk 38 by means of a lever 36. A shaft 50 is driven through piniongearing &c. 40, 41, 43, 45. 47, 48, 49 from the shaft 39 of the disk 38, and it in turn turns a tappetwheel 30 through bevel-gearing &c. 52, 53, 54, 55, and a drying-drum 80 through a belt 84. The dye &c. is contained in a series of bottles 10 kept in position in a rotary carrier 11 by latches 14 pivoted to the bottles. Each bottle has a neck closed by a stopper 13 and a longitudinal mouth 15, Fig. 10, containing some permeable colour distributing or applying material 16, for example, felt or sponge, through which the flow of dye &c. may be regulated by a clamp 105 having its ends 106, 107 bearing respectively against the mouth 15 and the material 16, and controlled by a screw. The carrier 11 is splined upon its shaft 21 so that it may be reciprocated when the position of the threads 17 is changed upon the drying-drum 80. The shaft 21 is driven through a ratchet-wheel 23 fast thereon by a pawl 24 carried by an arm 25 pivoted on the shaft 21 and actuated through a link 27 by the tappets 29 of the tappet-wheel 30 engaging with a rock arm 28. The pawl is moved idly over the ratchet-wheel by the action of tappets, the acting stroke being effected, with return to the first position, by a spring 280. A wiper carriage 68 is supported upon a bracket 110, adjustable by means of a slot and bolt so that the height of the wipers 65 may be varied. There is a series of rollers or wipers 65 corresponding in number to the series of colour distributors. The carriage 68 is rotated by equal gear 70, 71 from the shaft 21 of the carrier 11. Thus, when a different distributor 16 is brought into position against the threads 17 the wipers 65 are correspondingly changed. The threads 17 to be treated pass around a suitable tension-device, such as a set of rollers 18 mounted on an adjustable frame 19, then under and bearing against one of the colour distributors 16 and thence under the corresponding wiper 65 which removes surplus dye &c., through the steam chest 75 under rollers 78 therein. The steam may be supplied through a pipe 81 and a valve 82, preferably not under pressure. The consequent moisture is stated to set the colours. The steam may carry some fixing-substance to mordant the dye. A cock is provided for the escape of steam and condensed steam. From the steam chest 75, the threads pass over the drum 80 to a series of bobbins 85 through guides 86 attached to a reciprocating sliding bar 87. The bobbins 85 rotate and draw the threads through the machine by means of their friction heads 94 bearing upon friction disks 95. The drawing action can be augmented by the drum 80. Blending effects are produced by setting the carrier 11 so that the threads bear against two distributors 16 and also the two corresponding wipers 65. To produce alternation of colours or shades two oppositely acting ratchet-wheels with the corresponding pawls are provided.
