Endless Apron And Scrubber Patents (Class 68/39)
  • Patent number: 4095443
    Abstract: Method and apparatus for washing rugs and the like which includes conveying a rug upwardly along an inclined path, with the nap of the rug facing upwardly, then compressing the rug, preferably by a roller, at a location extending transversely to the inclined path of the rug. A jet of water and detergent is then directed toward the rug as it is conveyed past the compressing roller to thereby form a pool of water and detergent that is dammed by the roller, such pool of water and detergent being continuously agitated by the directed jet to clean the rug. A cleaning brush may also be added ascensionally to the directed jet, and compartmentalized collection means may be provided for collecting the water and detergent mixture separately from the cleaner rinse water, with the rinse water being recirculated through the washing system to reduce the water requirements of the washing operation.
