Abstract The present invention is a multi function apparatus that provides for the following:
a. The evacuation of air from a closed sealed container such as a wet fire hydrant barrel, dry fire hydrant system or similar structure or assembly.
b. The evacuation of liquid from a closed sealed container such as a wet fire hydrant barrel, dry fire hydrant system or similar structure or assembly.
c. The introduction of air to create pressure in an open or closed container such as a wet fire hydrant barrel, thy fire hydrant system or similar structure or assembly.
The invention may be deployed by an individual for the inspection, testing and trouble shooting of municipal or private water distribution systems. Most commonly used for the inspection, testing and evacuation of liquid from municipal and private water supplies necessary for fire suppression operations. The invention can be easily transported from place to place and deployed by a single individual.
Description Positive Pressure Gas-Liquid Evacuator While taking advantage of an energy source typical to a fire service, this invention provides a means to pressurize, prime or evacuate water from a fire hydrant or similar assembly.
Background The required testing, inspection and maintenance of water supplies for fire suppression operations is typically described in legislation. Often, this involves adding air pressure/
volume, removing air pressure/volume, priming a system or evacuating water from an assembly to prevent damage from freezing. Using a portable or fixed pressurized air supply as an energy source, the invention can be used to prime a fire hydrant, pressurize a fire hydrant or evacuate water from a fire hydrant. This is especially useful for dry fire hydrant installations where there is a risk of water freezing. Pressurizing a dry fire hydrant installation with air may also facilitate locating the intake or strainer installed into a body of water but beneath the water surface. The invention can be deployed by a single individual often saving the expense and preserving the time of a full fire engine crew.
Summary of Invention This invention pertains mostly to a device used by a fire service, private service company or individual property owner responsible for the inspection, testing and maintenance of a water supply required for fire suppression operations. This invention involves a main body apparatus and two attachments. The main body having plumbing, valves, couplings and a venturi priming device is designed to offer, at the end of a flexible tubing, the option of positive air pressure or a vacuum. This flexible non-collapsible self-coiling tubing terminates with a quick connect fitting that can couple to one of two attachments.
The first attachment is used to introduce or evacuate air from a container.
The second attachment is used to evacuate liquid from a closed container. Common plumbing adaptors will enable the invention to couple with assemblies having varying size orifices.
Air under pressure is introduced to an air nipple fitting at the top of the invention and prevented from initially pressurizing the invention by two valves. Opening one valve will energize a venturi primer (existing patent) providing for a vacuum at the end of the flexible self-coiling non-collapsible tubing (existing patent). Choosing the second valve option will provide for positive air pressure at the end of the flexible self-coiling non-collapsible tubing (existing patent). Selecting one option or the other depends on the attachment used and task at hand.
Attachment #1 is a device designed to attach onto the orifice of a fire hydrant or similar assembly. This device is designed with exterior plumbing including a compound pressure gauge, valve and quick connect air nipple fitting. This device allows for two functions.
Providing a vacuum to this device will remove air volume from the fire hydrant creating a negative pressure within the fire hydrant. This condition will prime the fire hydrant.
This vacuum is measured on the compound gauge. Closing the valve will maintain a vacuum within a sealed fire hydrant.
Providing a positive air pressure to this device will push the water out of the fire hydrant system to a point where the air can escape freely into the water source such as a static body of water. This positive pressure is measured on the compound gauge. This freely escaping air will rise within the body of water directly above the intake or strainer. This violent bubbling action at the surface of the body of water can be easily identified as the location of the intake or strainer.
Attachment #2 is a device designed to attach onto the orifice of a fire hydrant or similar closed assembly. This device is designed with plumbing including a quick connect air nipple fitting on the exterior that is open to the interior. A second plumbing fitting on the interior of the device is open to atmosphere on the exterior. Upon deployment, one end of a flexible non-collapsible tubing is attached onto the interior of the second plumbing fitting. The other end of this flexible non-collapsible tubing is guided inside the fire hydrant assembly and encouraged to fall freely to the bottom of the closed wet fire hydrant riser. The device is then secured onto the orifice of the fire hydrant. When enough volume of air is introduced through Attachment #2 into the fire hydrant, water is pushed from the fire hydrant riser to atmosphere through the flexible non-collapsible tubing. This concept is similar to the dispensing of an aerosol can.
Claims 1. A compressed air-powered Main Body Device offers the option of a positive or negative air pressure from a common terminus.
a. The evacuation of air from a closed sealed container such as a wet fire hydrant barrel, dry fire hydrant system or similar structure or assembly.

Detailed Description of Invention The invention in its entirety includes three separate items, the main body of the invention and two attachments. These three items are depicted separately in fig 1 Main Body, fig. 2 Attachment #1 and fig. 4 Attachment #2. The main body of the invention converts positive air pressure into an option of either positive air pressure or vacuum at a common terminus.
Figure 1 depicts the main body of the invention. Air under pressure enters the invention through air nipple fitting 1. This air is stopped at valve 2 and valve 3.
Opening valve 2 while valve 3 remains closed allows the air pressure to be recorded on compound gauge 5 and flow through appliances 4 to charge the flexible non-collapsible self-coiling tubing 7 with positive air pressure. The flexible non-collapsible self-coiling tubing 7 is terminated with a quick connect air fitting 8.
Opening valve 3 while valve 2 remains closed allows the air to flow along rigid pipe 12 & 14 and appliance 13 to enter a venturi Pump Primer 6. The Venturi Pump Primer converts positive air pressure to a vacuum. This vacuum is transferred along rigid piping 10, appliances 11 & 4 to the flexible non-collapsible self-coiling tubing 7.
This vacuum is recorded on compound gauge 5. The flexible non-collapsible self-coiling tubing 7 is terminated with a quick connect air fitting 8.
Figure 2 depicts Attachment #1 of the invention. This attachment is a device that would attach onto an orifice of an open or closed container such as a fire hydrant or similar assembly. This attachment once installed air-tight offers the option of introducing positive air pressure or vacuum to the container. The quick connect terminus 8 from the main body of the invention (fig.1) attaches to the air nipple fitting 1. This positive air pressure or vacuum is stopped by valve 2. When valve 2 is opened, positive air pressure or vacuum is recorded on compound gauge 7 and introduced to the container through appliance 3, rigid piping 4 & 5. This positive air pressure or vacuum can be trapped in the container by closing valve 2. Compound gauge 7 will continue to record any gain, loss or sustained positive air pressure or vacuum within the container. Figure 3 depicts the interior side of Attachment #1. Fitting 5 orifice is open to atmosphere.
Figure 4 depicts attachment #2 of the invention. This attachment is a device that would attach onto an orifice of a closed liquid filled container such as a fire hydrant or similar assembly. This attachment once installed air-tight allows for positive air pressure to be introduced to the container while forcing any liquid out to atmosphere in an aerosol dispensing type manner. The quick connect terminus 8 from the main body of the invention (fig.1) attaches to the air nipple fitting 1. The flexible non-collapsible tubing is attached to the interior side of fitting 3 (fig. 5). The distal end of the flexible non-collapsible tubing is then introduced into the orifice of the container, and encouraged to fall to the lowest point of said container. The device is then securely attached to the orifice of the container. By manipulating the valve 2 on the main body of the invention (fig. 1), the volume of air introduced into the container can be controlled manually until all the liquid has been evacuated. Figure 5 depicts the interior side of Attachment #2.
Fitting 3 orifice is open to atmosphere.
Detailed Description of Invention The invention in its entirety includes three separate items, the main body of the invention and two attachments. These three items are depicted separately in fig 1 Main Body, fig. 2 Attachment #1 and fig. 4 Attachment #2. The main body of the invention converts positive air pressure into an option of either positive air pressure or vacuum at a common terminus.
Figure 1 depicts the main body of the invention. Air under pressure enters the invention through air nipple fitting 1. This air is stopped at valve 2 and valve 3.
Opening valve 2 while valve 3 remains closed allows the air pressure to be recorded on compound gauge 5 and flow through appliances 4 to charge the flexible non-collapsible self-coiling tubing 7 with positive air pressure. The flexible non-collapsible self-coiling tubing 7 is terminated with a quick connect air fitting 8.
Opening valve 3 while valve 2 remains closed allows the air to flow along rigid pipe 12 & 14 and appliance 13 to enter a venturi Pump Primer 6. The Venturi Pump Primer converts positive air pressure to a vacuum. This vacuum is transferred along rigid piping 10, appliances 11 & 4 to the flexible non-collapsible self-coiling tubing 7.
This vacuum is recorded on compound gauge 5. The flexible non-collapsible self-coiling tubing 7 is terminated with a quick connect air fitting 8.
Figure 2 depicts Attachment #1 of the invention. This attachment is a device that would attach onto an orifice of an open or closed container such as a fire hydrant or similar assembly. This attachment once installed air-tight offers the option of introducing positive air pressure or vacuum to the container. The quick connect terminus 8 from the main body of the invention (fig.1) attaches to the air nipple fitting 1. This positive air pressure or vacuum is stopped by valve 2. When valve 2 is opened, positive air pressure or vacuum is recorded on compound gauge 7 and introduced to the container through appliance 3, rigid piping 4 & 5. This positive air pressure or vacuum can be trapped in the container by closing valve 2. Compound gauge 7 will continue to record any gain, loss or sustained positive air pressure or vacuum within the container. Figure 3 depicts the interior side of Attachment #1. Fitting 5 orifice is open to atmosphere.
Figure 4 depicts attachment #2 of the invention. This attachment is a device that would attach onto an orifice of a closed liquid filled container such as a fire hydrant or similar assembly. This attachment once installed air-tight allows for positive air pressure to be introduced to the container while forcing any liquid out to atmosphere in an aerosol dispensing type manner. The quick connect terminus 8 from the main body of the invention (fig.1) attaches to the air nipple fitting 1. The flexible non-collapsible tubing is attached to the interior side of fitting 3 (fig. 5). The distal end of the flexible non-collapsible tubing is then introduced into the orifice of the container, and encouraged to fall to the lowest point of said container. The device is then securely attached to the orifice of the container. By manipulating the valve 2 on the main body of the invention (fig. 1), the volume of air introduced into the container can be controlled manually until all the liquid has been evacuated. Figure 5 depicts the interior side of Attachment #2.
Fitting 3 orifice is open to atmosphere.
