Abstract:
An Improved system for killing roots in sewers without stopping the existing sewer flow, a portable system to eliminate the roots in the sewers, this system makes it possible to treat the roots by treating only the zone concerned and not the overall length of the drain of sewer. The invention enters the sewer by an opening and travels to the problem and inflates in order to retain the poison dispensed by the dispenser. This system makes it possible to more easily deal with problems of roots in the sewers more quickly and, which makes it possible to reduce the cost. All the zones touched by problems of roots can be treated, treatment limits the progression of the roots and destroys them, which makes it possible to prevent the over flow of sewers and the damage of the drains of sewers. The prevention of overflows of sewers makes it possible to protect our wild, aquatic life and our water supply. Basically to help save our environment.

     BACKGROUND 
     1. Field of Invention 
     This invention relates to a method for treatment of killing of root growth in sewers and under ground pipes specifically and improved method of treatment. 
     2. Description of the Prior Art 
     While working for the C&amp;C of Honolulu for more then 10 years, I′ve realized how threatening roots are to our sewer system and the amount of sewer spills, pipe damage, legal fees and the endangerment of our environment. I realized the methods that are used lack certain objections so I came up with an idea that would be able to not only treat roots in all areas of the sewer system, but also a cost effective method that could be used on a daily bases and achieve what other prior art may lack. 
     Originally previously used methods of treating roots in sewer pipes ignore the use of using the existing flow of sewer water to transport a root chemical to the specific zone without disrupting the flow of sewer water, where roots has intruded and restrict the chemical from flowing past the specific zone. 
     Numerous methods of treating roots in sewers have been provided, but they seem to require large equipment or a means of blocking the natural flow of sewer water, and treating large sections of pipe, which don&#39;t necessarily need treatment. By using my invention a specific zone of 1 ft or more from a single entrance such as a residential cleanout passing through the lateral and to the mainline, which needs to be treated without stopping the existing flow of the sewer water with a minimal amount of chemical. By using the exiting gravity flow of the sewer water to transport an activated root killing chemical to a specific zone, which is then brought to maturity by foaming to a greater height reaching the top of the sewer pipe within that zone, this system is also designed to travel to multiple concerned area&#39;s using one application of chemical. This method may also eliminate the mechanical method used to temporally remove root concerns, when used on a preventive maintenance schedule 
     All prior art suffer from a variety of disadvantages 
     
         
         
           
             a) In Horne&#39;s theory (U.S. Pat. No. 3,741,807 filed Jun. 26, 1973) 
             FIG. 3 to 11 shows that it would be very time consuming being that a line would need to be drawn from one entrance of a sewer pipe to another then the sled would need to be pulled to the zone to which treatment is desired. If a second entrance of sewer pipe is not permissible, which in many cases it&#39;s not, then Horne&#39;s theory could not be used. Horne also claims to spay and soak the entire sewer line from one entrance to the other. 
             b) Huff, (U.S. Pat. No. 3,606,862) 
             Huff claims 1. Apparatus for applying coating material to the interior wall of a pipe comprising: 
             A generally cylindrical applicator head for applying the coating material to the pipe wall, having a diameter smaller than the internal diameter of the pipe, said applicator head being adapted to traverse the length of the pipe in one direction and to receive the coating material under pressure through a supply connected thereto; 
             With all due respect for Huff&#39;s invention, the invention is related to Horne being that a moving device travels though a pipe and sprays the inner walls. In Huff&#39;s Abstract he discloses an apparatus to line pipes, lining is used to rehabilitate a pipe, meaning to reinforce the existing pipe from future malfunction. Furthermore Huff doesn&#39;t mention applying a root chemical to treat roots in a pipe, nor does he claim a restrictor.
           While my method is to use the velocity of the existing sewer flow to transport the root chemical to a desired location once it is brought to a consistency to travel to where the chemical restrictor is positioned, without disrupting the existing sewer flow   
         
             c) Monaghan, (U.S. Pat. No. 5,735,955)
           Monaghan, in claim 22. “The apparatus according to claim 13 wherein the nozzle sprays in a substantially 360. degree circumference”.   With all due respect for Monaghan&#39;s invention, I believe the invention is related to Horne and Huff being that a moving device travels though a pipe and sprays the inner walls. While again my method is to use the velocity of the existing sewer flow to transport the root chemical to a desired location once it is brought to a consistency to travel to where the chemical restrictor is positioned.   
         
             b) Tremblay (U.S. Pat. No. 4,811,869) 
             Tremblay claims “A powder dispensing device comprising a powder container, he does mention a window for the view of a scale of measurement, but doesn&#39;t mention a restrictor to restrict a root chemical. 
             d) Copeland (U.S. Pat. No. 4,690,305) 
             Copeland claims “A means for dispensing a concentrated aqueous chemical solution from a solid block of a wash chemical to a utilization point, which comprise” but doesn&#39;t mention a restrictor to restrict a root chemical. 
             e) Horne (U.S. Pat. No. 4,025,360) injects the root chemical and also needs to enter through a sewer manhole. 
             f) Other methods of removing roots require a mechanical method which uses uses cutters as a plumber would use a snake to clear a blockage, but this method is a temporary solution being that roots grow faster and thicker once they are mechanically removed. 
             g) Another method is used to treat roots, requires activating a chemical outside of the sewer pipe then dumping the matured chemical directly into the entrance of a sewer pipe which makes it difficult to travel long distances, and requires the entire length of pipe to be treated from one entrance to another to determine if the chemical has reached from one point to the other. This is very costly if there is only one root problem in a 300 ft sewer pipe. Although various methods have been described above through experience and research prior patents are not used today for treating roots in sewer pipes. 
           
         
       
    
     With all due respect to the inventors and their patents mentioned above, they all seem to lack the uses of the existing gravity flow to transport the root chemical under the roots and containing it in a specific zone. 
     SUMMARY OF THE INVENTION 
     The invention relates to a portable non-disruption of sewer flow system to eliminate the roots in the sewers, this system making it possible to treat the zones touched by problems of roots by treating only the zone concerned and not the overall length of the drain of sewer. The system according to the invention penetrates in the sewer by an opening for cleaning, travels to the zone, which poses problems and inflates in order to retain the poison applied by the applicator. This system makes it possible to more easily deal with the problems of roots in the sewers more quickly which makes it possible to reduce the costs. All the zones touched by problems of roots can be treated, the treatment limits the progression of the roots and destroys them, which makes it possible to prevent the overflows of sewers and the damage of the drains of sewers. The prevention of the overflows of sewers makes it possible to protect the environment, in particular the wildlife, the aquatic life, the supply water, and to avoid the closing of beaches, lakes, etc. In a general way, this system contributes to preserve the environment. 
     OBJECTS AND ADVANTAGE 
     Besides the objects and advantages of the Root Treatment System, as described in the above patent, several objects and advantages of the present invention are:
         (a) To provide a one step method root treatment system that will target a specific zone of sewer pipe using the minimal amount of root chemical, equipment, time and cost without disrupting the normal flow of sewer water. Previous methods are unsuccessful and possibly eliminated the mechanical step of removing these roots.   (b) To provide a root treatment system that will allow an activated root chemical to travel under intruding roots, to a distance in a sewer pipe using the gravity flow of sewer water to a specific zone then, have the chemical mature and work its way in the opposite direction of sewer flow and coat the entire root or roots where previous methods are unsuccessful.   (c) To provide a root treatment system that will confine the matured chemical in that confined space allowing the chemical to reach the top of larger pipes using my restrictor would contain the chemical in a zone causing a head and have the restrictor travel through the sewer pipe should the whole length of pipe need treatment where previous methods are unsuccessful.   (d) Further objects and advantages are to provide a root treatment system that will minimize the cost of treating roots in the sewer system, which cause sewer spill&#39;s that endangers our environment and water supply, the damage of sewer pipes which is costly to municipalities as well as homeowners and possibly replace the dangerous method previously used. Furthermore, preventing sewer spills, this invention may also prevent the closing of lakes, rivers and beaches and endangering plants, wildlife and aquatic life and protecting our environment and water supply.

     DESCRIPTION OF THE OPERATION 
     The advantage of using my invention, is to activate a root chemical within the sewer system by applying water, and use the existing gravity flow of sewer water to transport the activated root chemical, to the specific zone. Once the activated chemical has traveled to the specific zone with the exiting sewer flow, a restrictor restricts the root chemical from flowing further downstream from with that specific zone without any disruption of the actual sewer flow. My invention is fully assembled as shown in  FIGS. 1 ,  2 . 
     The root treatment system is first prepared by filling the air tank  33 , using air tank fill valve  37 , as shown in  FIG. 3 , with compressed air and filling the water tank  53 , using water tank fill cap  55 , as shown in  FIG. 4 . The system is transported using the wheeled carriage  7 , to the entrance of the sewer system. On the first treatment the root problem area may need to be inspected by using a sewer camera were a restrictor may be attached to the camera. If previous determination of the distance the roots are known the restrictor can be placed at the specific zone with no inspection needed. Once the distance is determined, the restrictor  1 , is sent through the sewer entrance as shown in FIGS.  22 , 24 ,  25 ,  26 ,  27 . Using the distance meter  15 , or the distant markers  29 , the expandable  1 , is inserted to the desired distance downstream from the root problem. 
     The expandable restrictor  1 , is then inflated by the operation of air fill valve  43 , the regulator  41 , will regulate the air pressure from air tank  17 , which will prevent the expandable restrictor  1 , of over inflation. The air flow meter  45 , measures the volume of compressed air flow to the expandable restrictor  1 , which gives the user a general idea when the expandable restrictor  1 , will start expanding, the pressure gauge  47 , allows the user to reassure that a full expansion has been reach and to regulate a full expansion should a deflation occur. 
     The protective braking bag  89 , protects the expandable bladder  79 , from foreign matter often found in the sewer system, and prevents the expandable bladder  79 , from over inflating. The adjustable strap  93 , allows the user to adjust the expandable bladder  79 , if a full expansion is not desired and bag tie  95 , secures the both ends of the protective braking bag  89 , to the two plugs  83 , and  85 , zipper  97 , allow the user to connect protective braking bag  89 , to other sewer equipment to perform as a restrictor. 
     The sealed plug  83 , and opened plug  85 , closes both end of expandable bladder  79 , as shown in  FIG. 11 . The opened plug  85 , allow the passage of compressed air to the expandable bladder  79 , while the sealed plug  83 , restricts any passage of air causing the expandable bladder  79 , to deflate. A non-expandable bladder sleeve  81 , and zip ties  87 , restricts the expanded section of the expandable bladder  79 , both ends, which prevents disconnection and deflation of the expandable bladder  79 . 
     The safety cable  21 , and flanged sleeve  23 , stiffens and secures the sealed plug  83 , expandable bladder  79 , opened plug  85 , and grace air line  31 , from separating. This also prevents any part of the root treatment system from disconnection while treatment is being performed, and allows a disconnection for maintenance. The grace airline  31 , allows the user to change the expandable restrictor  1 , without disassembling it, and to add an additional length to the actual distance desired, to reassure that the expandable restrictor  1 , has past down stream from the roots being treated. The dummy restrictor  51 , duplicates the size and inflation of expandable restrictor  1 , outside of the sewer system. 
     Once the expandable restrictor  1 , is in place and inflated, the chemical dispenser bottom cap  113 , is placed on the bottom of chemical dispenser  3 , to contain the root chemical  123 , scale window  107 , can be used to measure the volume of root chemical  123 , if a desired length of treatment is desired. The chemical dispenser  3 , is also used as a mixer to mix a two or more part chemical, by attaching lid  109 , to the top of chemical dispenser  3 , and turning in a top to bottom motion. Shield  105 , shields the spray from nozzle  106 , and contributes to the mixing. Once mixing is done the chemical dispenser bottom cap  113 , is removed and chemical dispenser  3 , is placed in the sewer entrance, screen  103 , will hold root treatment chemical  123 , and allow just the passage of water to activate the root chemical. 
     To start the treatment water tank air fill valve  63 , is turned on to build pressure in water tank  53 , the air pressure in water tank  53 , will cause water  137 , to flow to splitter  73 , which will divide the water  137 , into two separate water lines as shown in  FIG. 18 . One water supply line to dispenser  74  is connected to water on/off valve  77 , is turned to the on position, which supplies water  137 , to chemical dispenser  3 , that exits nozzle  106 , to activate root treatment chemical  123 , as shown in FIGS.  16 , 17 . 
     The free water supply line  75 , is also turned on to produce a flow of water  137 , in the sewer pipe  131 , if no sewer water  139 , is flowing at the time of treatment. A flow of water is need to transport the root chemical  123 , to the specific zone, in most cases the main sewer line has an existing flow, so getting the chemical to the main sewer line should be sufficient, as shown in  FIG. 22 . The agitator  99 , will produce an inflow turbulence which will enhance the maturity of the activated chemical  125 , while the expandable restrictor  1 , restrict matured chemical  127 , from flowing past the specific zone and cause this build up to reach the top of larger pipes. The average gravity flow of a sewer is 2 feet per second, the chemical holds it&#39;s maturity for approximately 5-6 minutes, once the calculation of the time it would take the activated chemical  125 , to travel to this distance the expandable restrictor  1 , can be pulled back while the matured chemical  127 , is still in it&#39;s mature stage covering a longer length of pipe if needed. 
     Once all root chemical  123 , is displaced from chemical dispenser  3 , water supply line to dispenser  74 , is turned off, the free water supply line  75 , is used to rinse the equipment while still in the sewer. Once this is completed, the air is released from expandable restrictor  1 , by the pressure release valve  49 , to deflate the expandable restrictor  1 , and air supply line  17 , is wound back in to revolving reel  11 . 
     While I have shown and described in considerable detail what I consider to be the preferred form of my invention, it will be understood by those skilled in the art that various changes may be made in the shape and arrangement of the several parts of the device, and that such details are not intended to limit the scope of my claims. 
     CONCLUSION, RAMIFICATIONS, AND SCOPE OF INVENTION 
     Thus the reader will see that the root treatment system of the invention provides a highly reliable, lightweight, and economical way to treat roots that has entered under ground pipe&#39;s that can be used by persons in the field of sewers. 
     While my above description contains much specificity these should not construed as limitations on the scope of the invention, but rather as an exemplification of one preferred embodiment thereof. Many other variations are possible. For example: 
     The restrictor can be made of various materials, shapes, and size, other materials can be as simple as a bread bag or made of in a shape as shown if  FIG. 2  And connected to other sewer equipment as shown in  FIGS. 1 ,  24 ,  26 ,  27 . The air supply line can be eliminated and cable can be used to transport the restrictor if expansion is not required.  FIG. 2  is a perfect example of the simplicity of the root treatment system. The restrictor and dispenser doesn&#39;t necessarily have to be at the same entrance of the sewer they can be detached at two separate entrances to treat a whole length of pipe where multiple root concerns accrue, the main purpose of the dispenser is to liquefy the chemical to travel under the roots and work its way back up stream being that roots tend to grow in the direction of the sewer flow which makes it impossible to cover both sides of the root using the dumping method. The parachute could be eliminated, but the parachute can help pull the restrictor for long distance and parachute could actually be a restrictor being that just a slight restriction will cause the chemical to foam. and the chemical it self becomes it own restrictor and hold back the rest of the chemical from flowing down stream. 
     There are many ways that the system can be rearranged, for example: the chemical dispenser extension  111  can be connected to the chemical dispenser in many different ways to have many different advantages, such as being used as a shoot to fill the chemical dispenser from ground level not shown in  FIG. 25 , in  FIG. 2  the expandable restrictor  1 , be connected to a handle when placing the expandable restrictor  1 , in a manhole. 
     The portable non-disruption of sewer flow root treatment system for the elimination of roots in the sewer system, uses the existing flow of the sewer system to transport an efficient amount of a foaming root chemical needed to treat a desired zone of pipe, the efficient amount of root chemical is brought to a consistency to travel via route of the existing sewer flow, to a location to be treated for the elimination of roots in the sewer system, without plugging the pipe and stopping the sewer flow. 
     Many modifications and other embodiments of the invention will come to mind to one skilled in the art to which this invention pertains having the benefit of the teaching presented in the foregoing description and the associated drawings. Therefore, it is to be understood that the invention is not to be limited to the specific embodiments disclosed and that modification and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for the purposes of limitation.
