SELF-HAMMERING, COPPER-BONDED STEEL GROUND ROD TOOL FOR LOCATING UNDERGROUND UTILITIES

Abstract

A unitary tool that combines a ground rod to a self-hammering mechanism in a trapped configuration. The ground rod has a length ranging between forty-two and fifty-two inches for facilitating the self-hammering functionality. The ground rod is made from copper-bonded steel for more effectively grounding an electrical connection than the prior art.

5. The unitary tool of claim 1, further comprising a clamp electrically connected to said copper portion outside of the hammering sleeve.

6. The unitary tool of claim 1, further comprising threading along the proximal portion; and wherein the one or more stops are screwed to the threading.

7. The unitary tool of claim 6, wherein the ground rod and the one or more stops slides relative to the hole diameter of the annular plug, whereby the proximal portion is in the trapped configuration.

8. A unitary tool operatively associating a self-hammering mechanism to a ground rod in a trapped configuration, comprising: the ground rod extending between a proximal portion to a pointed tip for a longitudinal length between forty-two and fifty-two inches; the ground rod comprising copper-bonded steel; the proximal portion having threading; the self-hammering mechanism comprising: a hammering sleeve slidably associated with the proximal portion; an annular plug connected to a distal end of the hammering sleeve, wherein the ground rod is slidable through and relative to an opening in the annular plug; and one or more stops screwed to the threading of the proximal portion, the one or more stops has a stop diameter exceeding a diameter of the opening of the annular plug, trapping the proximal portion is in the trapped configuration by preventing the proximal portion from slidably disassociating with the hammering sleeve; and a clamp electrically connected to said copper-bonded steel outside of the hammering sleeve.

DETAILED DESCRIPTION OF THE INVENTION

[0020] The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.

[0021] Broadly, an embodiment of the present invention provides a unitary tool that combines a ground rod to a self-hammering mechanism in a trapped configuration. The ground rod has a length ranging between forty-two and fifty-two inches for facilitating the self-hammering functionality. The ground rod is made from copper-bonded steel for more effectively grounding an electrical connection than the prior art.

[0022] Referring now to FIGS. 1 through 6, the present invention may include a unitary tool 100 combining a self-hammering mechanism 50 and a ground rod 10. The ground rod 10 extends from a pointed tip 12 to a proximal end 14. The proximal end 14 couples to one or more stops 22, which effectively create a radial flange or provide an effective increase in the circumference of the ground rod 10 at or near the very end of the proximal end 14. In certain embodiments, proximal end 14 may provide threading for operatively associating with the stops 22 that may be threaded fasteners, such as nuts or the like. The ground rod 10 may be generally cylindrical and have a longitudinal length ranging between forty-two and fifty-two inches. The ground rod 10 may be made of copper-bonded steel.

[0023] A hammer sleeve 16 may be dimensioned and adapted to slidably receive the coupling end 14. In certain embodiments, a distal end of the hammer sleeve 16 provides an annular plug 18 dimensioned to receive the proximal end 14 of the ground rod 10, while the proximal end 14 of the hammer sleeve 16 provides a solid pug 20 for engaging the proximal end 14 during the hammering process.

[0024] The hammer sleeve 16 is adapted to slide along a proximal portion the length of the ground rod 10 in a controlled manner due to the hole of the annular plug 18. The annular plug 18 and the opposing solid pug 20 and the stops 22 effectively trap the proximal end 14 in the lumen of the hammer sleeve 16 in a trapped configuration.

[0025] A rod clamp 24 may electrically connect the ground rod 10 to a wire clamp 28. The rod clamp 24 may be selectively secured along the length of the ground rod 10 by way of a set screw 26 or equivalent. A ground wire 30 electrically couples the wire clamp 28 to a transmitter 34 which can be electrically coupled to a target line 40 by way of a signal clamp 38 and transmitter wire 36, as illustrated in FIG. 6.

[0026] A method of using the present invention may include the following. The unitary tool 100 disclosed above may be provided. Referring to FIGS. 5A through 5C, a user 44 may contact the ground 32 with the pointed tip 12, typically near a suspected underground cable or pipe. Then the user 44 slides the hammer sleeve 16 upward, as illustrated in FIG. 5A, before sliding the hammer sleeve 16 down, as illustrated in FIG. 5B, so that the solid plug 20 drives the ground rod 10 in the ground 32. The user 44 repeatedly slides the hammer sleeve 16 up and down to insert the ground rod 10 into the ground 32 to a desired depth.

[0027] Then the user 44 electrically connects the transmitter 34 to the ground rod 10 by way of the clamps 28 and 24. This will electrically ground the transmitter 34, enabling the detection of underground utilities through, in certain embodiments, a receiver 46 and a propagated signal 42.

[0028] It should be understood, of course, that the foregoing relates to exemplary embodiments of the invention and that modifications may be made without departing from the spirit and scope of the invention as set forth in the following claims.
