The disclosure relates to spout fitting devices and more particularly pertains to a new spout fitting device for preventing a loss of plastic pellets from a feed tube to a suction tube when the plastic pellets are being removed from a hopper and more particularly from a railcar being used as a transportation hopper for the plastic pellets.
The prior art relates to adapter devices and includes a variety of adapter devices coupling an end of a first piping to an end of a second piping having unequal diameters. Known prior art does not include an adapter device enclosing the ends of the first piping and the second piping within an enclosed space.
An embodiment of the disclosure meets the needs presented above by generally comprising a sleeve being elongated from a first end to a second end. The first end and the second end are open. A chamber space is defined within the sleeve. The second end is configured to removably receive the feed tube of the railway car hopper into the chamber space of the sleeve. An end wall is attached to the sleeve and covers the first end. The end wall has an aperture extending therethrough configured to receive the suction tube. A securing member is mounted on the sleeve and is configured to releasably secure the sleeve to the feed tube wherein an outlet of the feed tube is positioned within the chamber space. A seal is attached to the end wall and covers the aperture to restrict the pellets from exiting the sleeve through the aperture.
Another embodiment of the disclosure comprises a method including the steps of mounting a sleeve on a feed tube in fluid communication with the railway car hopper such that a first end of the sleeve is positioned distal to the railway car hopper. The sleeve secures to the feed tube such that a free end of the feed tube is positioned within the sleeve. A suction tube extends through a seal closing the first end such that the seal forms a barrier around the suction tube to restrict pellets from flowing outwardly of the second end of the sleeve.
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 securing member 34 is mounted on the sleeve 12 and is configured to releasably secure the sleeve 12 to the feed tube 24 wherein an outlet 36 of the feed tube 24 is positioned within the chamber space 22. The securing member 34 normally comprises one or more threaded fasteners being threadably coupled to and extending through the sleeve 12, wherein the one or more fasteners is each abuttable against the feed tube 24 to frictionally restrict movement of the sleeve 12 relative to the feed tube 24. The one or more threaded fasteners typically includes at least a first threaded fastener 38 and a second threaded fastener 40. Each of the first 38 and second 40 threaded fasteners is correspondingly axially aligned with a first radius 42 and a second radius 44 of the sleeve 12. The first 42 and second 44 radii lie in a same plane with respect to each other.
A seal 46 is attached to the end wall 28 and covers the aperture 30 to restrict the pellets 26 from exiting the sleeve 12 through the aperture 30. The seal 46 has an opening 48 therein configured to receive the suction tube 32, wherein the seal 46 is configured to removably receive the suction tube 32 into the chamber space 22. The seal 46 includes a plurality of resiliently bendable flaps 50 for conforming to the shape of the suction tube 32. The resiliently bendable flaps 50 may comprise a silicone rubber material or any other conventionally bendable material. The seal 46 and the end wall 28 may also be a unitary structure, wherein the seal 46 forms the end wall 28 and has a central opening therein which is covered by the resiliently bendable flaps 50.
In use, the sleeve 12 is mounted on the feed tube 24 and in fluid communication with the railway car hopper such that the first end 14 of the sleeve 12 is positioned distal to the railway car hopper. The sleeve 12 secures to the feed tube 24 such that a free end of the feed tube 24 is positioned within the sleeve 12. The suction tube 32 extends through the seal 46 closing the first end 14 such that the seal 46 forms a barrier around the suction tube 32 to restrict pellets 26 from flowing outwardly of the second end 16 of the sleeve 12. The railway car hopper is actuated to dispense the pellets 26 from the feed tube 24 and the suction tube 32 collects the pellets 26 by suctioning the pellets 26 from the feed tube 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.
