Abstract: A machine for dyeing, bleaching, &c., comprises a plurality of separate dye kiers each of which is provided with a pump for circulating liquid and a valve for controlling the liquid flow. Each kier has a separate upper opentopped liquid compartment in direct communication with the corresponding compartments of the adjacent kier or kiers and with the remainder of the kier.  Valve means in the communications between the liquid compartments enable any one of the compartments to be placed out of or into direct communication with the adjacent compartment or compartments whereby some or all of the kiers may be connected together and used simultaneously for the same treatment or may be shut off from each other for simultaneous use in different treatments.  The valve means may comprise a series of slide valves 67, Fig. 10, arranged in a channel 65 through which liquid may flow between the upper compartments of the kiers.  The <PICT:0589147/IV/1> <PICT:0589147/IV/2> channel 65 receives liquid discharged from each kier through tubes 80 and upper and lower conduits 64, 70, respectively.  To facilitate mixing of the liquids when the kiers are connected together, alternate tubes 80 may discharge into the conduits 69 whilst the other tubes 80 are connected with conduits 70.  A kier 1, Fig. 1, comprises an upper compartment 4 and a lower compartment 3, separated by a removable lid 2.  A pump 10 passes liquid from the compartment 4 through a filter 6 and a valve 24 through materials such as loose fibres, hanks, or fabric, contained in an annular perforated holder 15.  The materials may be compressed by a pressure plate 17 operable by a nut 18 and a screw 19.  The rotary valve 24 comprises two passages 25, 26.  In the position shown liquid is drawn through the filter 6, tube 7, pump 10, passage 25, and valve ports 22, to pass outwardly through materials and to return to the compartment 4 through ports 23, passage 26, ports 31, and a discharge pipe 33.  When the rotary valve 24 is turned through 90 degrees the ports 22 communicate with the passage 26, and the ports 23 with the passage 25, so that the direction of flow of liquid through the materials is reversed. The liquid may be given a to and fro movement through the materials by closing the filter passage by a plate 48, opening a valve 51 in a byepass conduit 50, and closing the pipe 33 by a ball valve 52.  In an alternative construction for the treatment of materials in the form of cheeses or wound on cops or bobbins, the holder 15 is replaced by a holder 53, Fig. 5, which carries perforated tubes 54 on which the materials are mounted.  The holder 53 forms a seal around the valve 24 between the ports 22, 23, and has a central sleeve 55 which passes over the tube 56, Fig. 1.  The lid 2 is replaced by a lid, having no central aperture, which is secured to the wall of the chamber 3 by spring-pressed bolts.  In further modifications the rotary valve 24 may be replaced by a slide valve, and the holder 15 may be attached to the lid 2.
