Detailed Description of the Invention

The present invention comprises a plumbing tool having various embodiments. One preferred embodiment is shown in FIGS. 1-5, 7, 8, and 9; and a second embodiment is illustrated in FIGS. 6 and 11. FIGS. 12-15 illustrate yet another embodiment for the plumbing tool, whereas FIGS. 17, 18 and FIGS. 19, 20 illustrate a fourth and fifth embodiment, respectively, of the plumbing tool.

In the two embodiments for the plumbing tool disclosed in FIGS. 1-5, 7, 8, and 9, and FIGS. 6 and 11, there is seen the plumbing tool comprising a ring, generally illustrated as 10. As best illustrated in FIG. 2, for one embodiment of the plumbing tool the ring 10 defines an opening 12 extending through the circular structure of the ring 10. The circular structure of the ring 10 also has a channeled slot 14 and a pair of threaded apertures 16 and 18 (see FIGS. 2 and 6) which communicate with the opening 12 and are disposed in an opposed aligned relationship with respect to each other. The threaded apertures 16 and 18 terminate in recesses 20 and 22, respectively, disposed within the circular structure of the ring 10. A bolt 24 threadably passes through the pair of threaded apertures 16 and 18 such that by turning the bolt 24 in a predetermined direction, the opening 12 may be widened or narrowed. It is readily apparent that as the bolt is rotated counterclockwise (or tightened) the opening 12 is narrowed such that if the ring structure is secured to a cap assembly, generally illustrated as 26 in FIG. 8, tightening of the bolt 24 causes the ring structure to tighten around the cap assembly 26, more specifically around a plurality of teeth 28 that circumscribe the cap assembly 26. As was previously indicated, the cap assembly 26 is part of a faucet assembly, generally illustrated as 30 that, in addition to the cap assembly 26, includes handle 32, and spigot 34.

The plumbing tool of FIGS. 1-5, 7-9, and FIGS. 6 and 11 additionally comprise threaded apertures 36 and 38 which extend through the circular structure of the ring 10. A pair of threaded handles 40 and 42 is threadably secured within the threaded apertures 36 and 38 respectively. In order to firmly affix the pair of handles 40 and 42 within the threaded apertures 36 and 38, the circular structure of the ring 10 is provided with a pair of top threaded apertures 44 and 46 respectively communicating with threaded apertures 36 and 38, and wherein a pair of threaded bolts 48 and 50 respectively rotatably lodge such that upon tightening, the bolts 48 and 50 can respectively tighten against handles 40 and 42 to provide a stationary lodging of the handles 40 and 42 within the threaded apertures 36 and 38. The circular structure of the ring 10 may be formed with a plurality of teeth 52 such as to be capable of mating and engaging with the teeth 28 of the cap assembly 26.

With respect to the plumbing tool of FIGS. 6 and 11, instead of being formed with the channeled slot 14, the circular structure of the ring is divided into two semi-circular sections, 10A and 10B. The semi-circular sections 10A and 10B are separated by opening 12 and opening 56. Opposed in an aligned relationship and being separated by opening 56 is a pair of threaded apertures 58 and 60 which are the mirror image of apertures 16 and 18 respectively. Similarly to threaded apertures 16 and 18 respectively terminating in recesses 20 and 22, threaded apertures 58 and 60 respectively terminate into recesses 62 and 64. Bolt 66 threadably passes through apertures 58 and 60, similarly to bolt 24 passing through threaded apertures 16 and 18, in order that by tightening bolt 66 the opening 56 is narrowed. It is readily apparent that by loosening bolt 66, the opening 56 would widen.

As best illustrated in FIG. 6, semi-circular section 10A comprises threaded aperture 16, recess 20, threaded aperture 36 wherethrough handle 40 rotatably passes into in order to be stationarily secured therein by threaded bolt 48 passing through threaded aperture 44, threaded aperture 58, and recess 62.

Semi-circular section 10B is a mirror image of semi-circular section 10A. More specifically, semi-circular section 10B includes threaded aperture 18, recess 22, threaded aperture 38 wherethrough handle 42 threadably passes in order to be stationarily secured therein by a threaded bolt 50 passing into threaded aperture 46, threaded aperture 60, and recess 64. Each of the semi-circular sections 10A and 10B may be formed with teeth 52.

In operation for the plumbing tool of FIGS. 1-5, 7-10, and FIGS. 6 and 11, the handle 32 (see FIG. 1) is passed through the circular opening which the circular structure of the ring 10 defines until the latter has lodged around the teeth 28 of the cap assembly 26, as illustrated in FIGS. 1 and 8. When the circular structure of the ring has been disposed as such, bolt 24 (and bolt 66 in the event that the plumbing tool of FIGS. 6 and 11 is being employed) is tightened such that the circular structure of the plumbing tool has firmly engaged the teeth 28 of the cap assembly 26. The handles 40 and 42 may be easily employed now to turn cap assembly 26 in a predetermined direction in order to loosen the same for removal.

Turning now to FIGS. 17-20 for two other embodiments of the plumbing tool, there is seen in FIGS. 17 and 18 a hollow generally cylindrical body, generally illustrated as 60, comprised of a lower hollow cylindrical body 62 and an upper hollow cylindrical body 64 integrally bound to the top of the lower cylindrical body 62. The upper body 64 has a smaller diameter than the lower body 62 such that a tapering surface 66 is employed to interconnect the lower part of the upper body 64 with the upper part of the lower body 62. The lower body has a circular structure whose inside face is formed with a plurality of teeth 68, as illustrated in FIG. 18. The upper body includes a pair of opposed apertures that are diametrically situated with respect to each other. Slidably passing through the apertures 70 and 72 is a handle 74.

In FIGS. 19 and 20 the plumbing tool comprises a hollow dome-shaped body 76 whose lower portion thereof is internally formed with a plurality of teeth 78, as illustrated in FIG. 20. Integrally bound to the dome-shaped body, and generally axially aligned therewith, is an upper hollow cylindrical body 80. Similarly to hollow body 64, upper cylindrical body 80 is formed with diametrically opposed apertures 82 and 84 wherethrough a handle 86 may slidably pass.

In operation of the preferred embodiments of the plumbing tool of FIGS. 17-20, the cap assembly (with the handle 32 removed) is merely encircled with the lower part of the hollow cylindrical body 62 or the dome-shaped body 76 such that either the plurality of teeth 68 or 78 mate with and firmly lock between teeth 68 on the cap assembly 26. In such a position, the plumbing tool of FIGS. 17 and 18 and the plumbing tool of Figs. 19 and 20 may be easily turn the cap assembly 26 with the handles 74 and 86 respectively.

The final embodiment for the plumbing tool of this invention is that embodiment illustrated in FIGS. 12-16 and 21. In this embodiment of the invention, the plumbing tool comprises a first handle 90 and a second handle 92 pivotally secured to the first handle 90. The first handle 90 is formed with a semi-circular jaw 94 and with an arcuate protrusion 95 extending above the surface thereof. Similarly, handle 92 is formed with a semicircular jaw 96, and with an elongated slot 98. The elongated slot 98 has along its boundaries a plurality of arcuate channels 100 that are formed by and separated by partitions 102. Arcuate protrusion 95 removably lodges within a particular concrete channel 100 to fix the opening of the jaws 94 and 96 at a particular diameter. A bolt 104 slidably passes through the handle 90, through the elongated slot 98, and terminates in a washer or flange means 106 to firmly pivotally secure together the handle 90 with the handle 92. The semi-circular jaw 96 may be formed with teeth 108, and the semi-circular jaw 94 may be formed with teeth 110. Teeth 108 and 110 are adaptable to engage teeth 28 of the cap assembly, as illustrated in FIG. 12. Handle 92 is adaptable to move the arcuate protrusion 95 into and out of engagement with the arcuate channels 100, more specifically the partitions 102, in order to adjust an opening 112 between the end of the semi-circular jaw 94 and the end of the semi-circular jaw 96. Such adjustment can be accomplished by moving pivotally the handles 90 and 92 away from each other about to extreme points, thus moving arcuate protrusion 95 out of any arcuate channel 100 and enabling the bolt 104 to slide readily within slot 98 to either enlarge or lessen opening 112, depending on the direction of movement.

While the present invention has been described herein with reference to particular embodiments thereof, a latitude of modification, various changes and substitutions are intended in the foregoing disclosure, and it will be appreciated that in some instances some features of the invention will be employed without a corresponding use of other features without departing from the scope of the invention as set forth.
