ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of hand tools, and more particularly to tools for cleaning threaded fittings.
2. Description of Related Art
As can be seen by reference to the following U.S. Pat. Nos. 4,014,063; 4,575,892; 4,889,460; 4,899,409; 5,566,416; and 5,600,862, the prior art is replete with myriad and diverse tools for cleaning threaded fittings.
While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical electrical fitting tap.
As a consequence of the foregoing situation, there has existed a longstanding need for a new and improved type of electrical fitting tap, and the provision of such a construction is a stated objective of the present invention.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, the present invention provides an electrical fitting tap for retapping the hollow interior edge of a junction box or the like comprising a unit having two milled taps that are opposed and concentrically aligned at a joint provided with four opposing holes within which a cheater bar can be inserted. The center of each of the taps is open so that wires within the electrical fitting box can be threaded through the tool and positioned out of the way when the retapping is accomplished.
