Abstract: 14,125. Dargue, W., Dargue, F. L., and Barker, H. June 25. Dyeing ; washing.-In a dyeing, mordanting, or washing machine in which hanks are traversed vertically through the dye &c. liquor on carriers slung from rollers on a lifter-frame above the vat, means are provided for interlocking the controlling-levers of the gears which rotate the rollers and lift their frame, for locking the lever of the lifting-gear until the rollers are free to move into or out of their driving-sockets, and for automatically stopping the lifting-gear and the gear which traverses the frame and rollers away from the vat. Reference is made to Specification No. 7060, A.D. 1903. The hank carriers each consist of upper and lower rollers 47, 52, Fig. 12, connected by loose brackets 48, 51 and jointed arms 49, 50. The joints of the arms 49, 50 are knuckled to cause the arms to fold inwards when the roller 52 is raised towards the roller 47 to receive the hanks, The hanks are stretched by the weight of sand &c. contained in the hollow roller 52, and are prevented from lapping round the rollers by V-shaped guards 53, 54 of thin metal &c. attached to the brackets 48, 51. When in position above the vat, the rollers 47 at one end 14', Fig. 6, engage in sockets 13 on spindles 12, Figs. 1, 3, and 6, which are driven from worms 11. These worms are driven from a main shaft 1 through gearing controlled by a lever 8 and a clutch-rod within the shaft 1. Drums 5, 7 carrying the lifting and traversing ropes of the lifter-frame are similarly driven from shafts 3, 6 fitted with internal clutch-rods controlled by levers 9, 10. In the arrangements for interlocking the levers 8, 9 and for locking the lifting-gear lever 9, a box or guide 23 on the frame 16 is formed with guide-ways for vertical and horizontal bolts 26, 20 connected to the levers 8, 9. These ways overlap, and the bolts are cut away in rectangular notches, so that both are free to move when both levers 8, 9 are in their vertical or " off" positions ; movement of either lever 8 or 9 locks the other. The bolt 20 also carries two teeth 21, 22, which prevent it from being moved until a notched disc 15', driven synchronously with the wheels 2 and sockets 13 by a wheel 15 and one of the worms 11. presents its notches 18, 19 to the teeth 21, 22. This occurs when the sockets 13 are in position to receive or free the roller-heads 14<1>. The stopping-mechanism of the lifting-gear consists of a worm 27, Fig. 10, turning with the shaft 3 and driving a shaft 29 which carries a worm.wheel 28, a single-toothed wheel 31, and a locking-plate 35. The wheel 31 drives a loose wheel 32 on a stud 33, and the plate 35 co-operates with a stopplate 36 to lock the wheel 32 except while the tooth 31<1> is acting. When the gear has performed a predetermined number of revolutions, the wheels 31, 32 are stopped by a piece 34 on the wheel 32, and the wheel 31 then acts as a rack to slide the worm 27 along the shaft 3, carrying the clutch rod 3<1> with it until the clutch is in the "off" position. Two or more stops 34 may be provided on the wheel 32, and two or more teeth 31<1> on the wheel 31, according to the arrangements of the driving- gear. A similar arrangement is provided for stopping the rotation of the shaft 6 which drives the traversing-mechanism.
