The ideas presented here are protected by US Patents 7,819,345,  7,942,350,
      Canadian patent 2,693,158, and a soon to be numbered Canadian patent for a Spray Hose Chamber.
     The Spray Hose Chamber has been awarded a US Patent that can be seen below.
     I hope to license the inventions to US and Canadian companies.
 
     For the rest of the world, I encourage people to build and sell these systems anywhere
     except the US and  Canada.

     I will assist "rest of the world" companies with the construction of these systems for free.

       La patente canadiense 2.693.158 y una patente canadiense pendiente para la cámara de manguera de          pulverización.
      La Cámara de Mangueras de Spray ha sido galardonada con una Patente de EE.UU. cuyo número estará          disponible en breve.

      Espero licenciar los inventos a compañías estadounidenses y canadienses.
 
      Para el resto del mundo, animo a la gente a construir y vender estos sistemas en cualquier lugar excepto        los EE.UU. y Canadá.
      Asistiré a las empresas del resto del mundo, sin costo, con la construcción de estos sistemas.

The image above is the first page of the US Patent that protects the Spray Hose invention in the USA.

The above photo shows 200 ft of a spray hose that can protect a home from wildfire embers, and also confine a prescribed fire (RxFire). There is a spray nozzle every 10 ft that sprays water onto the adjacent area.

The picture above shows a house that is surrounded by the spray hose (shown in blue). A pump is pumping water
out of a swimming pool into the blue spray hose. The gray water spray is shown spraying vertically from the spray hose. 
A preferred direction would be an angle of 45 degrees from the ground away from the house, but is too difficult to show in the picture.
The 45 degrees would help stop the fire before it reaches the hose.



The two photos below show a closeup of how the spray hose surrounding the house is constructed.
At the top of the photo below is a fire hose that has a small hole for spraying water.
Below the fire hose are two rectangular sections of hose that have been glued together.
One rectangular hose section has a smaller rectangle cut from its center.
The other rectanglular hose section has TWO HOLES that are centered in the cut rectangle area.

TWO HOLES

The photo below shows the two rectangular hose sections glued to the longer fire hose section.

When water is pumped into the long fire hose, some the of the water exits the hole in the hose.
This water enters the chamber formed by the rectangular area removed from one of the rectangular 
hose sections. The water in the chamber then exits from the two hole shown in the photo.

If a hose has a single hole, the water exiting will form a narrow column. The water exiting the TWO HOLES
does not form columns, but actually forms a very wide and deep spray. The wide and broad spray pattern 
is very desirable for fighting a grassfire or low intensity wildfire. The spray is also useful for stopping embers
from reaching the house.




The two rectangular hose sections have a very low profile, and are flexible.
This makes them useful for creating a long spray hose with such nozzles.
Their low profile allows such a hose to be deployed from a reel.
Such a hose can also be folded and deployed from a storage cavity.

The image above is a Hale fire pump that drives the hose system.
It can deliver 300 gpm at 70 psi.




The image above is a swimming pool that supplied the water to the Hale pump.

A video showing two nozzles spraying can be seen HERE.
Note that the spray from the nozzles is very uniform across the deck planks.
The nozzles are 10 feet apart. They each have a flow of 6 gpm at 45 psi.
The spray is 18 ft high.
At 70 psi the flow rate is 15 gpm and the height is 20 ft.
