BACKGROUND OF THE DISCLOSURE
The disclosure relates to bit systems and more particularly pertains to a new bit system for facilitating extraction of stripped fasteners by permitting attachment of extraction bits to an air drive ratchet.
An embodiment of the disclosure meets the needs presented above by generally comprising a driving tool and a fitting coupled to and extending from the driving tool. A drill socket is coupled to a drill bit wherein the drill bit is selectively couplable to the fitting such that the driving tool provides a driving force to the drill bit. An extraction socket is coupled to an extraction bit wherein the extraction bit is also selectively couplable to the fitting such that the driving tool provides the driving force to the extraction bit.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
Each of a plurality of extraction bits 26 has a respective uniquely sized head section 28. The head sections 28 may be consistent with the variety which are conventionally known. A respective extraction socket 30 is coupled each extraction bit 26 wherein each extraction bit 26 is selectively couplable to the fitting 16 such that the driving tool 12 provides the driving force to the extraction bit 26. Each extraction bit 26 may also have a relatively short length to permit positioning of the extraction bit 26 in a tight space for engagement to and removal of the fastener 24. Each extraction bit 26 and extraction socket 30 may be formed from a single piece of material as shown in
In use, the desired drill bit 18 is coupled to the fitting 16 using the drill socket 20. The drill bit 18 is used to drill into the fastener 24 to remove material from the head 22 and prepare the fastener 24 for being extracted. The desired extraction bit 26 is then coupled to the fitting 16 in place of the drill bit 18. The driving tool 12 is then repositioned to engage the extraction bit 26 to the fastener 24. The driving tool 12 is then actuated wherein the extraction bit 26 extracts the fastener 24.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
