Beaver barrier

Abstract

The Beaver Barrier is a unique use of rubber and steel to form a barrier that will restrict where beavers build dams without harm to animals. The material is recycled tire parts woven together which forms a tube composed of connected rings which allow water to freely pass through but restricts animals from plugging or moving the natural course of the water. This unit prevents the animals from being able to dam the flow of water. The unit is so designed to allow for easy cleaning. The approximate life expectancy of a unit is over ten years. All materials used are non-toxic eliminating damage to water quality, or soil in any way. Natural black color can free unit from ice at first thaw. The unit has a built in harness allowing easy cleaning even if unit is completely submerged in soils, trash or water. Installation is simple, merely placing it upstream the aperture to be protected. The upstream end is anchored with a post. The downstream end of the structure can have a built in flare to adapt to structure size eliminating any possibility of beaver getting between the unit and the protected structure.

I claim:  
     
         1 . Steel encased rubber form ring prevents rusting and resists chemical damage and is material from recycled tires.  
     
     
         2 . Steel inside rubber repells beaver biting to penetrate unit.  
     
     
         3 . Flexability of unit discourages removal by animals.  
     
     
         4 . Design has too many openings to be plugged with floatsum, debris.  
     
     
         5 . Sealed ends eliminates plugging with foreign matter.  
     
     
         6 . Innerty rubber eliminates polution.  
     
     
         7 . No harm can come to animals.  
     
     
         8 . Flexability to withstand animal intrusion frustrates animals.  
     
     
         9 . Steel inside rubber repells beaver atttempts to crush unit.  
     
     
         10 . Suspension yoke enhances cleaning of unit.  
     
     
         11 . Removable of expansion spacers allows for easier shipping by collapsing the unit until at the instalation site where they are replaced in the unit to tighten the cables.
