The disclosure relates to welding devices and more particularly pertains to a new welding device for welding in confined areas.
The prior art relates to welding devices and blow torches. Existing devices have standard cylindrical gas tanks or connect with a hose to a gas tank. Such devices lack a tank incorporated into a handle. Existing devices also do not include a rotating adjustable welding tip.
An embodiment of the disclosure meets the needs presented above by generally comprising a gas tank having a handle portion and an extension portion. Each of the handle portion and the extension portion is cylindrical. A valve assembly is coupled to the gas tank and comprises a tank receiver, a tube stem, a valve housing, and a control valve. The tank receiver selectively receives a distal end of the extension portion. The tube stem is coupled to the tank receiver. The tube stem is in fluid communication with the gas tank when the tank receiver is engaged with the extension portion. The valve housing is coupled to, and in fluid communication with, the tube stem. The control valve is coupled within, and in fluid communication with, the valve housing. A tube neck is coupled to, and in fluid communication with, the control valve. A welding tip is coupled to the tube neck.
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 valve assembly 22 is coupled to the gas tank 12. The valve assembly 22 comprises a tank receiver 24, a tube stem 26, a valve housing 28, a control valve 30, and a stop ring 32. The tank receiver 24 is coupled to the gas tank 12 with the tank receiver 24 threadably receiving the outer collar 18 of the distal end. The tube stem 26 is coupled to the tank receiver 24. The tube stem 26 selectively engages the inner nipple portion 20 of the distal end to be in fluid communication with the gas tank 12 when the tank receiver 24 is engaged with the extension portion 16.
The valve housing 28 is coupled to the tube stem 26. The valve housing 28 has a bypass channel 34 in fluid communication with the tube stem 26 and a valve aperture 36 extending from an outer face 38 through to the bypass channel 34. The control valve 30 is coupled within the valve housing 28 and is in fluid communication with the valve housing 28. The control valve 30 has a valve stem 40 threadably engaged within the valve aperture 36 and a valve knob 42 coupled to the valve stem 40. The valve knob 42 may have a knurled grip face 44. The valve stem 40 may have a threaded portion 46 and a smooth blockage portion 48. The smooth blockage portion 48 may have a pointed tip 50 to engage a pointed receiver end 52 of the valve aperture 36 for full closure of the bypass channel 34. The stop ring 32 is threadably engaged with the threaded portion 46 of the valve stem to lock the control valve 30 in a desired position.
A tube neck 54 is coupled to the control valve 30. The tube neck 54 is in fluid communication with bypass channel 34 of the control valve 30. The tube neck 54 may form a rounded angle between 135° and 180°. A welding tip 56 is coupled to the tube neck 54. The welding tip 56 may have a fixed portion 58 and a rotatable portion 60 rotatably coupled to the fixed portion 58. The fixed portion 58 has a faceted section 62 and a tapered section 64. The rotatable portion 60 is coupled to the tapered section 64.
In use, the user secures the gas tank 12 and adjusts the control valve 30 to the desired output and lights a flame coming from the welding tip 56. The user then adjusts the rotatable portion 60 of the welding tip to achieve the desired flame before using the apparatus 10 to create welds in difficult to reach places.
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.
