  "title": "Apparatus for jetting liquid onto fibrous material",
  "abstract": "An apparatus for jetting high-pressure liquid streams into fibrous materials that includes a quick change cartridge device loosely fitted into a body member. The cartridge includes an orifice plate to produce the liquid streams and a filter between the source of pressurized fluid supplied to the jet and the plate. A seal between the cartridge and the jet body relies on internal operating pressure within the jet body to effect sealing action.",
  "claims": [
    "1. An apparatus for jetting liquid onto fibrous material comprising: an elongated body, there being a longitudinal chamber in said body, said chamber extending through at least one end of said body and having upper, lower and sidewalls, there being a slot through said body from said lower wall; an elongated cartridge positioned in said chamber said cartridge resting on said lower wall and having an open portion facing upward and a wall facing downward having a longitudinal row of orifices therethrough, said row being aligned with said slot, said orifices being in communication with said open portion; means for sealing around said slot between said cartridge and said lower wall; a removable closure attached to said one end for sealing said chamber; and means for supplying pressurized fluid to said chamber through said upper wall.",
    "2. The apparatus as defined in claim 1, including a first filter positioned adjacent to and above said row of orifices and a second filter positioned between said means for supplying pressurized fluid and said upper wall.",
    "3. The apparatus as defined in claim 1, there being clearance between said cartridge and the upper and side walls of the chamber.",
    "4. The apparatus as defined in claim 1, said cartridge having a bottom surface resting on said lower wall, said means for sealing being an O-ring seal attached to said bottom surface, said seal extending out from said surface.",
    "5. The apparatus as defined in claim 4, including a slide attached to said cartridge at one end, said slide extending outward from said bottom surface beyond said seal, there being a recess in said lower wall at the other end of the chamber for accommodating said slide when said cartridge is in position in said chamber.",
    "6. The apparatus as defined in claim 4, said seal being an elastomeric seal."
