Title: Improvements in or relating to rotary washing and like machines
IPC: D06F39/08

Abstract: <PICT:0765358/IV(b)/1> <PICT:0765358/IV(b)/2> A rotary garment dyeing or like machine having a work container 5 enclosed in a stationary casing 6 with a liquid inlet at its lower part and provision for outlet of such liquid at a higher level from one end of the work container to the exterior of the casing, is characterized in that a settling tank 22 is disposed between the levels of the outlet and supply points to allow normal gravitational return flow from one to the other and is provided with a vertically adjustable overflow pipe 27 whose setting controls the "dip" within the casing.  The invention may be applied to an end loading machine as described in Specification 688,076 having a hollow trunnion 10, bearings 11 and a driving pulley 12.  The container 5 has perforated ribs associated with liquid scoops 15, and intervening perforated ribs 16 communicating with "V" pockets defined by radial webs 17 connecting the end wall 9 of the container 5 to a diaphragm 18 within the container.  As the container rotates these pockets empty themselves through passages 19 in the trunnion 10 into a stationary collecting box 20 connected by a pipe 21 to the tank 22.  A return pipe 23 connects the tank 22 to the casing 6.  A partition 24 divides the tank 22 into two intercommunicating compartments 25, 26, the smaller compartment (26) having an outlet pipe 28 leading to a drain and controlled by a valve 29. This compartment 26 may have a hinged top 30 for the addition of detergent material to the washing liquid.  The top 31 of the compartment 25 may also be hinged.  The overflow pipe 27 slides in a gland 32 in the tank bottom and is connected to a pipe 33 leading to the drain.  The height of the overflow pipe 27 may be manually adjusted by means of a lever 35 and link 34.  Overflow and consequent discharge of scum occurs whenever the total volume of liquid in circulation is increased by condensation of steam admitted to the casing 6 through a pipe 39 for heating purposes. Continuous discharge may be secured by means of an auxiliary supply of water bled at 40 from the main pipe 41.  The pipe 40 is connected through a rigid pipe 43 fixed in the tank wall and a rubber hose 44 to a float controlled inlet valve 45 on a bracket 27a fixed to the overflow pipe 27.  The pipe 40 may include a shut-off valve 42 connected by a link 46 to the outlet valve 29 so that neither of these valves can be opened without closing the other.ALSO:A rotary dry-cleaning machine having a work container 5 enclosed in a stationary casing 6 with a liquid inlet at its lower part and provision for outlet of such liquid at a higher level from one end of the work container to the exterior of the casing, is characterized in that a settling tank 22 is disposed between the levels of the outlet and supply points to allow normal gravitational return flow from one to the other and is provided with a vertically adjustable overflow pipe 27 whose settling controls the "dip" within the casing.
