The disclosure and prior art relate to splicing devices and more particularly pertains to a new splicing device for repairing tubing.
An embodiment of the disclosure meets the needs presented above by generally comprising a pair of housings. Each housing comprises a barrel, which is open-ended. A pipe, which is externally threaded, is positioned in and rotationally coupled to the barrel. The pipe is configured to be threadedly inserted into a respective segment of a tubular substrate so that the tubular substrate is drawn into a first end of the housing to sealably couple the pipe to the tubular substrate. A first coupler is coupled to a second end of one of the housings. A second coupler is coupled to a second end of other of the housings. The second coupler, being complementary to the first coupler, is positioned to couple to the first coupler to couple the one of the housings to the other of the housings. Concurrently, the pipes are sealably coupled to sealably couple two segments of the tubular substrate.
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
A pipe 18 positioned in and rotationally coupled to the barrel 14. The pipe 18 is externally threaded, as shown in
A first nut 22 is fixedly coupled to the pipe 18 adjacent to a second end 24 of the housing 12. The pipe 18 protrudes through the first nut 22, as shown in
A first barrel nut 30 is coupled to the barrel 14 proximate to a midpoint 32 of the housing 12, as shown in
A second barrel nut 36 is fixedly coupled to the pipe 18 proximate to the flare fitting 34. A plurality of protrusions 64 is coupled to and extend from the second barrel nut 36. A sleeve 38 is positioned over the second barrel nut 36 and extends to the first barrel nut 30. The sleeve 38 is malleable so that the sleeve 38 is configured to be crimped. A plurality of grooves 40 is positioned in the sleeve 38. Each protrusion 64 is positioned in a respective groove 40 to couple the sleeve 38 to the second barrel nut 36.
A third barrel nut 42 is threadedly coupled to the pipe 18 adjacent to the second barrel nut 36. The third barrel nut 42 is positioned to be rotated relative to the pipe 18 and the sleeve 38 so that the sleeve 38 is crimped between the third barrel nut 42 and the first barrel nut 30 to frictionally couple the housing 12 to the tubular substrate.
A washer 44 is positioned between the second barrel nut 36 and the third barrel nut 42, as shown in
Each of a plurality of ribs 46 is coupled to and extends perpendicularly from the first barrel nut 30 into the barrel 14 to define a gap 48 between the ribs 46 and the pipe 18, as shown in
A plurality of tabs 50 is coupled to and extends from the second barrel nut 36, as shown in
A first coupler 52 is coupled to a second end 54 of the one of the housings 26. A second coupler 56 is coupled to a second end 58 of the other of the housings 28. The first coupler 52 comprises a female hose coupler 60 and the second coupler 56 comprises a male hose coupler 62. The second coupler 56, being complementary to the first coupler 52, is positioned to couple to the first coupler 52 to couple the one of the housings 26 to the other of the housings 28. The pipes 18 are sealably coupled to sealably couple two segments of the tubular substrate.
In use, the pipe 18 is partially inserted into the tubular substrate. A first wrench is positioned on the first nut 22 and a second wrench is positioned on the first barrel nut 30. Rotation of the first nut 22 relative to the first barrel nut 30 drives the pipe 18 into the tubular substrate, drawing the tubular substrate into the barrel 14 and sealably coupling the pipe 18 to the tubular substrate. The first wrench then is moved to the third barrel nut 42. Rotating the third barrel nut 42 relative to the first barrel nut 30 crimps the sleeve 38 onto the tubular substrate. With the one of the housings 26 coupled to a first segment of the tubular substrate and the other of the housings 28 coupled to a second segment of the tubular substrate, a user is positioned to couple the male hose coupler 62 to the female hose coupler 60 to splice the two segments of the tubular substrate.
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 elements is present, unless the context clearly requires that there be only one of the elements.
