  • references herein to washing include other similar operations such as hot or cold rinsing operations, hot treatment operations, such as are commonly referred to as boiling operations, and preliminary washing operations.
  • a laundry washing machine comprises an inner cage rotatable with in an outer cage in contact with a washing medium, the articles being caused to travel through the inner cage in the opposite direction to the flow of washing medium in the outer casing.
  • a washing medium may be admitted at one end and steam and/ or detergent may be admitted at different points of the outer cage so that different regimes of operation are maintained in different sections of the inner cage through which the articles being washed are caused to pass in succession in transit from one end of the inner cage to the other.
  • washing medium is admitted to predetermined points of the outer cage intermediatethe ends thereof to maintain predetermined liquid levels at various points of the outer cage, by-pass ducts being provided as required to assist in maintaining the required levels.
  • the inner cage is perforated and provided with a series of inwardly directed heaters to ensure that articles being washed are continuously agitated and maintained in circulation within the inner cage, such articles being lifted to a high level and then allowed to fall towards the lower part While the cage is in rotation.
  • the inner cage is provided with a series of scoops around its periphery, such scoops being arranged in a series of parallel peripheral rows so that liquid is caused to flow from the space within the outer cage into the inner cage to maintain an eflicient washing action upon the articles.
  • the outer cage may be provided with a series of inwardly directed fin-like portions extending towards and nearly into contact with the inner cage so as to assist in providing separate zones where different operating regimes are maintained and to prevent the through flow of washing medium lengthwise of the outer cage and cansing said washing medium to flow in successive paths into and out of the inner cage to maintain an efiicient washing action on articles being treated.
  • the inner cage and the outer cage are preferably arranged at a small inclination to the horizontal so that the articles being treated tend to shift progressively along the inner cage from one end to the other.
  • the equipment may include a drying section for articles leaving the final washing stage, said drying section being provided either by an integral part of the inner cage,
  • Articles leaving the inner cage may fall into a section of the outer cage from which said articles are lifted out of the washing medium by means of an elevator conveyor, and said conveyor may be associated with a presser roller to eliminate surplus liquid.

  • a laundry washing machine comprising a closed liquid-holding outer cage 11 housing a relatively long perforated inner cage 12 rotatable within the cage 11 and in which various regimes of operation are maintained.
  • a common feature in all the embodiments described is that articles to be washed are received at or near one end of the inner cage 12 and are moved progressively or step-bystep through this cage towards the other end, and at least the major part of the washing medium is admitted to the plant adjacent said other end of the inner cage while the spent washing medium is taken away adjacent the point where incoming articles .are admitted to the inner cage.
  • the progressive movement of the articles being washed can be effected in various ways.
  • this displacement of the-articles is obtained by the. fact that the outer cage 11 and the inner cage 12 are both slightly inclined to the horizontal.
  • the inner cage 12 is maintained in rotation and it may, if desired, bereversed in direction from time to time.
  • the latter contains articles at different positions of its length, which are being subjected to various regimes of operation, that is to say they are being subjected to various, andprogressive, Washing operations, and are moved progressively through the inner cage.
  • FIGS. 1 and 2 a progressive and continuous movement of articles within the inner cage is obtained by the fact that the inner cage 12 and the oute: cage 11 .are slightly and adjustablyinclined'to the horizontal. This embodiment will now be described it greater detail.
  • an outer cage '11 of-substantiall; circular shape is supported on a frame member 15 whicl in turnis pivotally mounted at 16 on a ground suppor' not separately shown but represented by the ground l-inr 1'7, and a screw adjustment device 18 is provided to permit the inclination of the frame '15 to the horizontal t( be adjusted.
