DESCRIPTION FIGS. 1-6

[0066] An overall description of the present invention is illustrated in FIG. 1. The two major pieces of the invention are the ground rod driver unit built in the housings 30,31 and the auger tipl5.The auger tip has tapered internal threads 32 FIG.2 which bite into the ground rod 10 FIG. 1. The driver unit is driven by a standard drill motor through the drive pin 16 to the chain drive sprocket 83 FIG. 6. Driving the other drive sprocket 79 FIG. 6 through the chain 74 FIG. 6. This rotates the cam chuck 14 FIG. 1.The cam chuck when rotated has internal roller pins 43,44,45 FIG. 3 that are jamed into the ground rod by the cam chuck body 41 FIG.3 which has flat portions 46,47,48 that decrease the diameter of the drive pins jamming them into the ground rod 10 and theirby rotating the ground rod 10.

[0067] FIG. 4. showes the ground rod 51 installed in the ground by the rotation of the auger tip 53. The drawing showes a gap around the rod because the tip is a bigger that the rod diameter. This gap then is filled with conducting medium61 FIG. 5 such as copper sulfate and sea salt to achieve better contact with the ground. FIG.5. showes in an expanded view the fill gap around the ground rod 60.

[0068] FIG. 6 showes a cutaway view of the internal chain drive mechinism utilized to Couple the rotational energy from the motor driver to the cam chuck.

[0069] Operation FIGS. 1,2,3,4,5,6

[0070] FIG. 1 The ground rod driving system is powered by a standard electricans dill motor connected to the main housing by the rubber pad 23 and the motor strap 22 and buckel 21.The motor chuck is attached to pin 16 and tighened. The next procedure is to hand tighten the auger tip 15 to the ground rod 10. The next procedure is to slide the ground rod 10 into the cam chuck clearence hole about four feet from the auger tip 15. The next procedure is to plug the drill motor into an approprate power source (115 v.a.c.) and stand the ground rod vertical to the ground and starting the drill motor screwing the ground rod 10 into the ground. The drill motor will lower by the amount the ground rod 10 is driven into the earth and the operator can stop the drill motor at a comfortable level .The cam chuck 14 will release when the motor stops and allow the operator to lift the drill motor up about two feet and start the procedure again until the ground rod is driven to ground level where the drill motor is stopped and the driver unit is then lifted off of the ground rod compleating the driving procedure. The operator then fills the gap around the ground rod with the conductive slurry in a squeez bottle which finishes the installation.

[0071] FIG. 2 FIG. 2 shows the auger tip body 30 with the cast auger spiral 31 and the internal tapered threads 32 that bite into the ground rod when the motor driver is rotated pulling the ground rod into the ground.

[0072] FIG. 3 FIG. 3 showes a cutaway of the cam chuck body 41 which is uniquely machined to press the roller pins 43,44,45 onto the ground rod 40 by centrifical force and cam action thereby rotating the ground rod and augering it into the ground. The roller pin holder 47 keeps pins at the proper place in the chuck body 41.

[0073] FIG. 4 FIG. 4 shows an installed ground rod 51 in the earth 50 driven in by the motor driver and pulled there by the rotated auger tip 53. The gap around the ground rod caused by the larger diameter auger tip is then filled by a conductive slurry.

[0074] FIG. 5 FIG. 5 is an exploded view of FIG. 4 to better see the gap around the ground rod and showing the conductive slurry 61 that is placed in the gap giving more surface area of the conductive material to the ground.

[0075] FIG. 6 FIG. 6 showes a cutaway of the motor driver unit to show the chain 74 and the chain links 80 that couple the drive from the drive pin 86 through the sprockets 79,83 and the sprocket collars 78,82 to the cam chuck 76 that rotates the ground rod.

[0076] Conclusions,Ramifications,and Scope

[0077] The ground rod installation system takes the heavy work out of a nasty job that no electricians like to do. It is also much safer as the installer is standing on the ground and not swinging heavy hammers or using ladders. The system is also quite a lot quicker to install the ground rods and one person can install many more per day without fatigue. the system also improves the grounding properties of the rod since the hole produced by the auger tip has more surface area to the ground and the conducting slurry can also leach into the surronding earth making it more conductive and safer with lightining and trancients.
