  • myinvention consists partly in so arranging the various units employed in the process of laundering that generally speaking the articles to be laundered enter the process at the highest elevation and are routed downward therefrom through the various units emerging at the lowest elevation.
  • iii-Fig.1, I, II, IILIV indicate the first to fourth floors respectively in the laundry building.
  • Bundles of articles to be laundered are delivered in bulk to the feeding or classification, table 1 on the fourth floor where they are opened and their contents are placed upon the elevating feeding-conveyor 2 driven by a motor 3, which .feedingconveyor delivers them to a distributing conveyor 4 operated by a motor 5-.
  • the distributing conveyor is reversible and selectively feeds from either end into twometering bins 6, 7 each having three compartments 6*, 6", 6 and 7, 72'7", fron which the work is fed to two washing machines 8, 9 arranged to discharge into the branches of a conveying and storing chute-l0 which delivers the work into an extractor 11, from which it is carried by a chute 12 to a continuous drying tumbler 13 delivering through a chute 14 upon a table 15 on the first or finish floor, the apparatus upon which floor will belater described.

  • the various components of the several laundry bags originally delivered to the table 1 on the fourth floor are assembled and wrapped ready for delivery.
  • the'laundering process regardless of the variations therein, as for examplethe option al treatment subsequent to the extracting operation, and especially between the distributing table 15 and the wrapping table, is an approximately continuous one, and at least sniliciently so that the contents of the several original bundles will arrive at thewrapping table very nearly together so that they may here-assembled and wrapped for delivery in V a single bundle with a minimum of identifying effort.
  • bins as at 10 unequal capacities of units in successive operations of the process, may be equalized, andbatteries of similar units in parallel may be employed Where the individual capacity is below the requirement of the process as a whole.
  • smaller units may be em ployed, as upon the'first floor, then upon the second and third floors in the example illustrated.
  • the only substantial conveying power required is that necessary to raise the articles tobelaundered to the level of the feeding table and thence to the feeding hoppers; the articles progressing in steps to the finishing room by gravity; and handling of the articles in thefinishing room being easily accomplished manually in connection with the conveyors indicated since here the bulk passing through the prior steps in the process is necessarily separated into small amounts.
  • said metering means being lo cated above the floor upon which said wash ing machine is located, and operator-controlled means for effecting delivery of such a predetermined batch from said metering means to said laundry washing machine, whereby during one laundry washing operation, another predetermined batch of work may be metered out for the following laundry washing operation, with the result that the operation of said laundry washing machine is substantially continuous, interrupted only by the emptying and loading of its chamber, and with the further result that the floor on which the washing machine is located is not cluttered up by laundry work awaiting metering.
  • Laundry apparatus comprising a laundry washing machine having a plurality of equal-sized,circumferentially arranged loadreceiving chambers, each adapted to receive as aload a predetermined batch of laundry A batches, said metering means being located above the floor upon which said washing machine is located, and operator-controlled means for efl'ecting delivery of such predetermined metered batches from said metering means to said laundry washing machine, whereby during one laundry washing operation, a suflicient number of predetermined batches of laundry work may be metered out for the following laundry washing operations, with the result that the operation of said washing machine is substantially continuous interrupted only by the emptying and the loading of its chambers, and with the further result that the floor upon which the washing machine is located is not cluttered up by laundry work awaiting metering.
