Definitions

  • the dishes may be positioned upon it directly, and conveyed through the machine while being held properly and with such yielding support as to prevent likelihood of damage or breakage.
  • the position of the dishes during their travel through the machine is essentially upright, or somewhat inclined, thus assuring complete drainage of the wash fluids before the dishes leave the machine.
  • the construction of the conveyor is essentially open throughout its entire extent so that the dishes maybe placed as desired directly upon the conveyor, and so that the wash sprays have full and complete access thereto, regardless of the particular location of the dishes thereon.
  • the wash arms are located above and below the conveyor and arranged to discharge their wash sprays directly upwardly and downwardly upon the dishes, through the conveyor in the case of the lower wash arms, the open construction making possible this free passage of the sprays through the conveyor without substantially reducing the eiiectiveness thereof.
  • the conveyor is thus rapid and easy to load and unload, fully protects the dishes during their travel through theme-chine, and provides for a highly effective washing action from wash arms located conveniently above and below the conveyor with respect to both fiat ware and hollow ware as well as silver.
  • a continuous conveyor adapted to be driven through the washing and rinsing comessary for the operator or attendant to load the dishes into a rack, since they may be placed directly on the web and without requiring any special orientation thereon.
  • the separating members on the conveyor are of sufficiently resilient construction and are so arranged with respect to the structural members of the conveyor that they provide resilient support for the dishes and maintain them out of contact with the body of the conveyor. This further facilitates rapid loading and unloading of the dishes and provides protection against.
  • the separating fingers of these supporting members are so arranged that if desired a rack of the usual type may be placed thereon, as may be desirable for handling silverware or otherwise, and the rack will be safely supported during travel with the conveyor through the washing and rinsing cycle.
  • An additional object is to provide such a conveyor wherein the dish supporting and separating members are arranged to provide dish re DC recesses which extend both laterally and longitudinally of the direction of travel of the partments of the dishwashing machine, and this conveyor is equipped with dish supporting and separating members which include upwardly projecting finger portions arranged in spaced and aligned relation both laterally and longitudinally of the conveyor to define dish receiving recesses.
  • dish receiving spaces or recesses defined by their finger portions provide adequate support for each dish, tray or like article during passage through the dishwashing machine in any position in which the article is mounted on the conveyor, 1. e., either laterally or longitudinally of its direction of movement, and it is accordingly not necconveyor for quick and easy loading and unloading.
  • Another object is to provide a continuous conveyor for a dishwasher which includes resiliently yieldable portions forming sup-ports for the dishes and other articles to be washed to maintain the dishes out of contact with the structural parts of the conveyor for protection against shock during loading and transporting of the dishes.
  • each of the dish supporting and separating members is formed of a single length of resilient wire formed to provide the desired dish separating and dish supporting portions.
  • FIG. 1 is a diagrammatic side view, partly broken away, showing a dishwashing machine embodying a continuous conveyor unit in accordance with the present invention

  • Spacers 80 are provided between adjacent flight wires 10 laterally of the conveyor, and each of these spacers is shown as similarly formed from a single length of wire. It will be seen that each spacer includes a forward pair of loops 8
  • the fingers on the flight wires are aligned in spaced relation both longitudinally and laterally. of the conveyor in such manner as to define a plurality of longitudinally extending recesses 81 and laterally extending recesses 88 for'receiving the articles to be washed.
  • the recesses 88 can be loaded with" dishes 90 of different sizes and shapes as well as with larger articles such as the trays 9
  • the longitudinally extending recesses 81 can be similarly employed for receiving articles to be, washed, particularly for large articles such as trays and the like which may be too long to be mounted crosswise of the conveyor.
  • the flight wires and spacers 80 constructed and arranged as shown, positive protection is provided against contact between any of the dishes-and the relatively stiff or rigid cross rods 65.
  • the loops IT on the flight wires interfit as shown in Fig. 7 in such manner that eachloop extends above one of the cross rods, and with the flight wires formed of resilient wire, the loops thus form resilient supports which act to cushion the dishes during loading and unloading of the conveyor, even if the dishes should be accidentally dropped into place.
  • the loops 1! thus cushion all of the lateral recesses 88- as well as alternate longitudinal recesses 87, and in the longitudinal recesses which donot contain the loops, the portions 85 of the spacers 80 similarly act as resilient supports for the dishes.
  • the fingers 15 may be provided as shown in Figs. 6 to. 8 with guard caps 95 of flat, thimble-like shape, 'formed of a suitable material such as nylon or other plastic, each of these guards being held on the finger by a rivet 96 and providing a cushion on the upper end of the finger.
