Abstract: 7060. Dargue, W., Dargue, F. L., and Dargue, A. W. March 27. Dyeing; washing.-Relates to a dyeing, mordanting, or washing machine of the type in which hanks or skeins on endless carriers supported by rollers on the upper edges of the vat are traversed vertically through the dyeing &c. liquid by the rotation of the rollers. The driving-gear comprises, in addition to that of the rollers, means for lifting the whole series of rollers, carrying them away from the vat, and depositing them on a receiver used for supporting the rollers while hanks are being charged or discharged on to or from the carriers. The carrier-rollers 23, Fig. 2, run in open bearings 34<1>, Figs. 1 and 2, in lifter rails 34, which normally rest in end pockets on the vat 1 and are provided near each end with cross-connected pedestals 35 carrying pulleys 37 round which lifting-ropes pass. Motion is transmitted from the main gearing to the rollers 23 through a shaft 19, worms 20, wheels 21, spindles 22, and driving-sockets engaging the ends of the rollers 23, all these parts being carried by the side frame 2<a>. The worm 17 for driving the shaft 19 is driven from the main shaft 3 through direct and reversing wheel trains put into gear by means of a lever 27 operating a double clutch-piece 9 on the shaft 3. The piece 9 is keyed to a rod within the hollow shaft 3, and moves along the shaft with a sleeve, which is constrained by inclined slots and fixed pins so as to move axially when its crank 29 is oscillated from the lever 27. Similar arrangements of levers 67, 68, clutches 60, 62, and direct aud reversing trains are used in the driving-gear connecting 5, 6 to the main shaft 3 ; the levers 67, 68 and duplicates thereof at the other end of the frame 2<a> are connected by links 67', 68'. Worms on the shaft 5, 6 gear with wheels 71, 72, 92 on the shafts of winding-drums 76, 77, 94 carrying ropes for raising the rollers 23 &c. towards an overhead carriage and for traversing the carriage along its supporting girders away from the vat. One pair of ropes 78, attached one each to the drums 76, 77, passes over fixed overhead pulleys, round guide-pulleys on the carriage, under pulleys 37 on the beam 36 connecting the first pair of pedestals 35, up round other guide-pulleys, and is finally attached to fixed adjustable hooks at the end of the girders further from the drums 76, 77. A second pair of ropes on the same drums is similarly arranged with regard to the other pedestals 35, and a third pair on the drum 94 is arranged on overhead pulleys for traversing the carriage in either direction. The receiver on to which the rollers 23 &c. are carried from the vat 1 consists of a series of cranked holders 41, Figs. 8 and 9, pivoted to a rail 42 which is supported by end casings 44 running on rails 46. The holders 41 rest against each other, but may be tipped over as shown in Fig. 8, to give free access to any one. The receiver is moved along the rails 46 by means of a hand-wheel shaft 50 geared to the wheel axles by a chain 47 and sprocket-wheels 49, 45<1>. When the rollers 23 are in the holders 41, the rails 34, Figs. 1 and 2, are forced apart by means of screwed shafts 38 engaging with nuts on the pivoted pedestals 35, so that they can be lifted away while the hank-carriers are being discharged and recharged. These carriers consist of laths 102, Figs. 15 and 16, connected at the middle and ends by links 103, 104, and formed with ridges 102<1> at intervals to separate the hanks. To avoid riveting, parts of the laths are stamped or cut and then clinched over the underlying parts of the links 104. Driving-teeth 23<1> on the rollers 23 engage with the links 104. To prevent contact of the dye &c. with the bolts of the vat, these bolts are arranged within the wood of the sides, ends, and bottom. The corners are bound with angle-plates formed with eyes on the top to facilitate the lifting of the vat. Steam is supplied to the vat through branches connected to a main pipe and arranged each with a stop-cock and with a series of perforations which are nearer together at the end farthest from the main pipe. According to the Provisional Specification, hanks of wool, silk, &c. are treated, the vat may be of porcelain, and the steam is supplied through the spaces between double metal cones in order to promote the circulation of the dye &c. liquor.
