Definitions

  • a device for discharging a fireextinguishing agent includes a cylinder and a cassette tank [30] Forelgn Apphcamm Pnomy Data containing a specified fire-extinguishing agent housed Sept. 25, 1972 Japan 47-96484 i the cylinder
  • the tank is aimightly Sealed within the cylinder but is capable of being taken out of and put [52] US. Cl 169/77, l69/88, 239/309 back into the housing when desired
  • a high pressure Cl. gas cartridge is ecured to the housing and a breaking [58] Fleld Search 169/9, 31 31 P; lever is used to break a seal on the cartridge.
  • Portable fire extinguishers are commonly used for quickly extinguishing small fires and for aiding in the control of larger fires, particularly when large fire extinguishing equipment is unavailable.
  • These devices typically include a cylindrical tank which houses a fire extinguishing agent under pressure and a hose attached to the tank. To operate the device, the user turns a valve (or inverts the device) to allow the pressurized extinguishing agent to be expelled from the tank towards the fire.
  • Such devices obviously can contain only a small amount of pressurized extinguishing agent and, therefore can be used for only a short period of time before they must be refilled. Furthermore, when refilling is necessary, this must be done professionally, usually by returning the device to the manufacturer or to a qualified service technician.
  • the seal on the gas cartridge is broken and highly pressurized gas is directed toward the cassette tank via connecting pipes.
  • This gas stirs the fire extinguishing agent in the tank, breaks a seal located between the tank and a passage leading to the fire extinguisher nozzle and as a result, forces the agent out through the nozzle.
  • the fire extinguishing agent or the gas cartridge is exhausted, one merely needs to replace the same with another.
  • FIG. 1 is a side view, shown partly in cross-section, of one embodiment of the invention
  • FIG. 2 is a top view of FIG. 1;

  • FIG. 10 is a sectional view taken along line 8-8 of FIG. 8.
  • a cassette tank 2 containing a specified powder or liquid fire-extinguishing chemical is housed in a cylinder 1.
  • the threaded lid 4 the protrudent edge of the connecting piece 3 and the elastic member 5 fixed to the spiral lid 4 fixed to the spiral lid 4
  • the eassette is capable of being removed from and put back into the cylinder in an air-tight arrangement as desired.
  • the main cylinder 1, the lid body 8 and the connection member 9 are fixed with the clamping mean 28.
  • the connection member 9 and the handle 17 are connected together by clamping means 18 and by the residual pressure release valve 32 (see FIG. 4).
  • the lever 19 pivotally mounted at 20 to the handle 17 causes the breaking lever 14 to slide up and down air-tightly in the connection member 9 through the O-ring packing l6. Ordinarily, however, the lever 19 is prevented from moving by the safety plug 21 and the stop member 22.
  • the lower edge 15 of the breaking lever 14 is placed opposite the seal 12 of a pressure cartridge 11 which is mounted through the packing 13.
  • a first passage 24, for high pressure gas, is provided in the connection member 9 and a second passage 25 is provided in the connecting piece 3.
  • the upper part of this connecting piece 3 is fitted into the connection member 9 through the O-ring packings 10 so that the first and second pas- Sages 24 and 25 communicate with each other.
  • First passage 24 is also made to communicate with the cartridge 11 when the seal 12 is broken, and passage 25 is designed to communicate with the interior of cassette tank 2 when high pressure gas from the cartridge forces open the elastic member 5.
  • the upper end of a fireextinguishing agent supply pipe 7 is mounted air-tightly to the connecting piece 3 and is closed by the sealing element 6.
  • an opening 38 in the fire-extinguishing agent supply pipe 7 can be made to communicate with the hose 29 through the fire-extinguish-agent supply passages 39 and 40.
  • the stop member 22 is broken and the lever 19 is pivoted about point 20. This lowers the breaking lever 14 causing the lower edge 15 thereof to break the seal 12 of the gas cartridge 111.
  • the highly pressurized gas inside the cartridge passes through the first and second passages 24 and 25, forces open the elastic member 5, enters the cassette tank 2, stirs the fire-extinguishing agent contained therein, forces the fire-extinguishing agent through opening 38 of the supply pipe 7 and breaks the seal 6.
  • the fire-extinguishing agent then passes through the passages 39 and 40 and is discharged through the nozzle 30 of the hose 29 in the desired direction.
  • a cassette tank 2 containing a specified fire-extinguishing agent is housed in a main cylindrical l.
  • the two are secured together through the protrudent cylindrical top of the cassette tank 2, the threaded lid 4, the protrudent edge of the connecting piece 3, the bent edge of the outer pipe 33 and the packing 36.
  • the cassette tank 2 can be taken out and put back in and kept air-tight as desired.
  • the upper end section of the inner pipe 7 is fixed to the connecting piece 3, and as can be seen in FIG. 4, the main cylinder 1 and the lid body are screwed to gether, the lid body 8 and the connection member 9 are bolted to each other, and the connection member 9 and the handle 17 are clamped by the clamping means 18 and the residual pressure release valve 32.
  • the lever 19 which is pivotally mounted to the handle 17 causes the breaking lever 14 to slide up and down air-tightly through the O-ring packing 16. Ordinarily, the lever 19 is prevented from turning by the safety plug 21 and the stop means 22.
  • the lower edge of the breaking lever 14 is placed opposite to the seal 12 of the gas cartridge 11 which is mounted to the connection member 9 through the packing 13.
  • a first passage 24 for high-pressure gas is provided in the connection member 9 and the upper part of the connecting piece 3 is air-tightly fitted in the connection member 9 through the O-ring packings 10.
  • the second passage 25 for high-pressure gas is provided in the connecting piece 3 so that the first and second passages 24 and 25 communicate with each other.
  • the first passage 24 is made to communicate with the gas cartridge 11 when the seal 12 is broken.
  • the second passage 25 in this embodiment is made to communicate with the outer pipe 33 of the coaxial pipes 7 and 33.
  • a plurality of recessed parts 34 are provided at various positions in the outer pipe 33. These recessed parts 34 are made to contact the inner pipe 7 to thereby embrace and support the inner pipe 7.
