     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     While the various features of this invention are hereinafter illustrated and described as providing a hose assembly wherein the internally threaded member initially has an external peripheral surface of a particular configuration, it is to be understood that the various features of this invention can be utilized singly or in various combinations thereof to provide a new hose assembly that can be utilized with internally threaded members other than the particular internally threaded member illustrated in the drawings. 
     Therefore, this invention is not to be limited to only the embodiments illustrated in the drawings, because the drawings are merely utilized to illustrate one of the wide variety of uses of this invention. 
     Referring now to FIGS. 1 and 2, a typical prior known hose assembly is generally indicated by the reference numeral 20 and comprises a flexible hose 21 having opposite ends. Only the opposite end 22 is illustrated in FIGS. 1 and 2 with the understanding that the other opposite end of the flexible hose 21 is coupled to an externally threaded member for coupling to an internally threaded member that is swivelly mounted on an end of another hose in order to provide an extension therewith in a manner well known in the art. 
     An internally threaded member 23 formed of any suitable material, such as metallic material, plastic material, etc., has an internally threaded opening 24 interrupting an end 25 of the internally threaded member 23 and terminating adjacent an inwardly directed annular flange 26 that forms part of the other side 27 of the internally threaded member 24 and is received in an annular groove 28 of a flared end 29&#39; of an internal metallic coupling member 29 that is adapted to be inserted into the end 22 of the flexible hose 21 and be crimped thereto together with an external metallic ferrule member 30 all in a manner well known in the art. 
     In this manner, the internally threaded member 23 swivels on the end 22 of the flexible hose 21 and readily permits the same to be finger coupled to an externally threaded part of a liquid dispensing spigot or the like by the user engaging his fingers against the external peripheral surface 31 of the internally threaded member 23 and rotating the internally threaded member 23 in the proper direction to couple onto an externally threaded part of a dispensing spigot that is received in the internally threaded opening 24 of the internally threaded member 23 in a manner well known in the art. 
     Usually the external peripheral surface 31 of the internally threaded member 23 is provided with a plurality of serrations 32 and/or projections 33 to facilitate the finger coupling or uncoupling operation as the case may be. 
     Nevertheless, it has been found that the finger coupling operation should be enhanced by providing an annular member over the external peripheral surface 31 of the internally threaded member 23 so that the external peripheral surface of that annular member will be more finger friendly in the coupling and uncoupling operation of the hose assembly. 
     For example, see the aforementioned U.S. patent to Magarian, U.S. Pat. No. 4,058,031 and the aforementioned U.S. patent to Swisher, U.S. Pat. No. 4,805,933 whereby these two U.S. patents are being incorporated into this disclosure by this reference thereto. 
     It is believed according to the teachings of this invention that the annular member being disposed on the external peripheral surface of the internally threaded member can be further enhanced if the same is formed of a SANTOPRENE material as such material is a soft surface material that is non-slippery when wet or dry. 
     It is further believed according to the teachings of this invention that such annular member of SANTOPRENE material can be either snap-fitted onto the internally threaded member to be carried thereby or can be molded directly thereon so that the annular member will rotate in unison with the internally threaded member when a person is finger coupling or uncoupling the hose assembly to or from an externally threaded part of a liquid dispensing spigot or the like. 
     &#34;SANTOPRENE&#34; is a registered trademark of the Monsanto Corporation of St. Louis, Mo. and it is well known that there are numerous SANTOPRENE materials sold by the Monsanto Rubber Chemicals Division, Monsanto Industrial Chemicals Co., 260 Springside Drive, Akron, Ohio., SANTOPRENE being a thermoplastic elastomer which exhibits rubber-like properties. 
     Thus, it is believed according to the teachings of this invention that at least one of such SANTOPRENE materials will uniquely function to form the annular member of this invention for the internally threaded member of the hose assembly of this invention. 
     Referring now to FIGS. 3, 5 and 6, the new hose assembly of this invention is generally indicated by the reference numeral 20A in FIG. 6 and parts thereof similar to the parts of the hose assembly 20 previously described are indicated by like reference numerals followed by the reference letter A. 
     The hose assembly 20A of this invention has the flexible hose 21A provided with an internally threaded member 23A swivelly mounted on an end thereof in the same manner as the internally threaded member 23 of the hose assembly 20. However, an annular member 34 of SANTOPRENE material is disposed over and against the external peripheral surface 33A of the internal threaded member 23A and has an external peripheral surface 35 that somewhat conforms to the external peripheral surface 33A of the internally threaded member 23A and is adapted to be finger engaged for swiveling the internally threaded member 23A in unison therewith for coupling or uncoupling the hose assembly 20A to an externally threaded part of a dispensing spigot or the like. 
     As previously stated, the external peripheral surface 35 of the annular member 34 when formed of SANTOPRENE material is a soft surface and is non-slippery when dry or wet so as to enhance the finger coupling and uncoupling operation for the reasons previously set forth. 
     Since the internally threaded member 23A now has the annular member 34 disposed thereon, the parts 23A and 34 now define a new internally threaded assembly that is generally indicated by the reference numeral 36 in FIGS. 3, 5 and 6. 
     It is believed that the member 34 of the internally threaded assembly 36 of this invention can initially comprise a tubular part 37 as illustrated in FIG. 4 having an internally smooth peripheral surface 38 that is approximately the same diameter as an annular shoulder 39 on the internally threaded member 23A and is stepped below the external peripheral surface 33A thereof as illustrated in FIG. 4. However, by stretching the member 37 onto the internally threaded member 23A so that the internal peripheral surface 38 of the tubular member 37 goes over the external peripheral surface 33A of the internally threaded member 23A, a trailing portion 40 of the tubular member 37 will snap fit into the recess 41 defined by the annular shoulder 39 in the manner illustrated in FIG. 5 so as to secure the annular member 34 of this invention in its final position to form the internally threaded member 23A for the hose assembly 20A and for the purposes previously set forth. 
     However, it is believed that the annular member of SANTOPRENE material or even of any other desired plastic material could be injection molded onto the internally threaded member 23A to secure the same together for the same purpose as snap-fitting the member 34 in place. 
     For example, reference is now made to FIGS. 7, 8 and 9 wherein another internally threaded assembly of this invention is generally indicated by the reference numeral 36B and parts thereof similar to the parts of the internally threaded assembly 36 of FIGS. 3-6, are indicated by like reference numerals followed by the reference letter &#34;B&#34;. 
     As illustrated in FIGS. 7, the internally threaded member 23B together with or without the coupling member 29B is disposed in a chamber or cavity 42 of a molding apparatus 43, the chamber 42 of the molding apparatus 43 defining an annular chamber that corresponds in configuration to the annular member 34 of FIGS. 3, 5 and 6. 
     As illustrated in FIG. 8, suitable polymeric material 44 is injection molded into the cavity 42 to be molded against the external peripheral surface 33B of the internally threaded member 23A so as to subsequently harden or vulcanize and form the internally threaded assembly 36B illustrated in FIG. 9 whereby the external peripheral surface 35B is adapted to be finger engaged for coupling and uncoupling to an externally threaded part of a liquid dispensing spigot or the like for the reasons previously set forth and should the plastic material 44 comprise a SANTOPRENE material, the material 44 will have the characteristics of being a soft surface and non-slippery when wet or dry for the reasons previously set forth. 
     Therefore, it can be seen that this invention not only provides a new hose assembly and a new internally threaded member for such a hose assembly, but also this invention provides a new method of making such a hose assembly and a new method of making an internally threaded member. 
     While the forms and methods of this invention now preferred have been illustrated and described as required by the Patent Statute, it is to be understood that other forms and method steps can be utilized and still fall within the scope of the appended claims wherein each claim sets forth what is believed to be known in each claim prior to this invention in the portion of each claim that is disposed before the terms &#34;the improvement&#34; and sets forth what is believed to be new in each claim according to this invention in the portion of each claim that is disposed after the terms &#34;the improvement&#34; whereby it is believed that each claim sets forth a novel, useful and unobvious invention within the purview of the Patent Statute.
