BEST MODE FOR CARRYING OUT THE INVENTION

(10) The best mode for carrying out the invention is presented in terms that disclose a preferred embodiment of a fire hydrant, combination ratcheting wrench and hook spanner. This preferred embodiment, is shown in FIGS. 1 through 9, and is comprised of a combination fire hydrant ratcheting wrench and hook spanner 10, for use on a fire hydrant 12, and is comprised of a wrench body 20 having a top 22, a bottom 24, a left side 26, a right side 28 and a lower portion 30. The top 22 has a cover recess 32 and an outwardly extending handle 34 on the body lower portion 30.

(11) The wrench body 20 is made of plated steel and includes a number of cover tapped holes 36 in the cover recess 32, as illustrated in FIGS. 3 and 4. The wrench body outwardly extending handle 34 has a rectangular configuration and includes at least two handle lock notches 38, as shown best in FIG. 4.

(12) The wrench body 20 incorporates a first flanged circular hollow cavity 40, a second flanged circular hollow cavity 44, a third flanged circular hollow cavity 48, and a fourth recessed flanged circular hollow cavity 52. The above cavities contain a mating first pawl depressed indention with a threaded hole 42, a second pawl depressed indention with a threaded hole 46, a third pawl depressed indention with a threaded hole 50, and a fourth pawl depressed indention with a threaded hole 54, as depicted in FIG. 4. The flanged element of each cavity is defined as an inwardly facing protrusion at the underside portion of the wrench bottom. The protrusion is wide enough to interface with the edge of a ratchet socket for retention purposes on the body's bottom 24.

(13) In order to loosen or tighten a cap or a fitting 56 that incorporates outwardly extending tabs 58, the wrench body 20 contains three integrally shaped hooks consisting of a first hook spanner 60 on a portion of the body's left side 26, a second hook spanner 62 on a portion of said body's top 22, and a third hook spanner 64 which is on a portion of said body's right side 28, as illustrated in FIGS. 1-4. The first hook spanner 60 is preferably sized to interface with a tab 58 of a four inch cap or fitting 66. The second hook spanner 62 is preferably sized to interface with a tab 58 of a one and one half inch cap or fitting 68, and the third hook spanner 64 is preferably sized to interface with a tab 58 of a two and one half inch cap or fitting 70, as depicted in FIG. 6.

(14) An alternate ability to tighten a cap or a fitting 56 incorporates two additional spanner configurations, a first spanner indentation 72 located on the body's left side 26, and a second spanner indentation 74 located on the body's right side 28, as shown in FIG. 7. The first spanner indentation 72 is preferably sized to interface with a tab 58 of a two and one half inch cap or fitting. The second spanner indentation 74 is preferably sized to interface with a tab 58 of a four inch cap or fitting 66.

(15) A ratchet pawl 76 is positioned within in each pawl depressed indention 42, 46, 50 and 54. A ratchet spring 78 pre-loads the ratchet pawl 76 and a pawl screw 80 rotatably positions the pawl 76 within each depressed indention 42, 46, 50 and 54, as depicted in FIG. 4.

(16) A first interchangeable ratchet socket 82 with peripheral teeth is located within the body's first recessed flanged circular hollow cavity 40 and preferably has a pentagonal shaped one and one quarter inch hollow aperture 84 therethrough,

(17) A second interchangeable ratchet socket 86 with peripheral teeth is located within the body's second recessed flanged circular hollow cavity 44 and preferably has a pentagonal shaped seven eighth inch hollow aperture 88 therethrough,

(18) A third interchangeable ratchet socket 90 with peripheral teeth is located within the body's third recessed flanged circular hollow cavity 48 and preferably has pentagonal shaped five eighth inch hollow aperture 92 therethrough,

(19) A fourth interchangeable ratchet socket 94 with peripheral teeth is located within the body's fourth recessed flanged circular hollow cavity 52, and preferably has a pentagonal shaped one half inch hollow aperture 96 therethrough,

(20) The above ratchet sockets are interchangeable, in order from upper to lower of the hollow apertures or may be replaced with other configurations according to the needs of the fire district or area.

(21) A cover 98, located within the cover recess 32, has a plurality of cover attaching holes 100. The cover 98 is fastened to the body 20 with wrench cover screws 102 that are inserted through attaching holes 100 into the cover tapped holes 36, as illustrated in FIGS. 1-4, 6 and 7.

(22) A handle grip 104 slideably encompasses the outwardly extending handle 34 and includes a handle grip latch assembly adjustment means. The grip 104 has a latch opening 106 on an upper portion thereof, a spring-loaded latch assembly 108, which includes a latch spring 110 within the latch opening 106, and a latch pin 112 that retains the latch assembly 108 in the latch opening 106.

(23) The handle grip 104 is locked in place when it simultaneously contacts the wrench body 20 and interfaces with the top handle lock notch 38. For a fully open position, the handle grip 104 embraces the lower handle lock notch 38 and is controlled by the latch assembly 108 which is spring-loaded to lock into the notch 38 and unlock when manually depressed. It is anticipated that a plurality of notches 38 could also be utilized to permit intermediate locked positions.

(24) During operation the combined ratcheting wrench 10 may loosen or tighten pentagonal shaped implements, such as hydrant caps or valves, by utilizing the ratchets. To remove or replace fittings such as reducers and increasers, the combined ratcheting wrench 10 employs the spanner hooks or spanner indentations formed with the body. The position of the wrench may loosen when connected on a wrench top surface 114 and tighten when connected on wrench bottom surface 116.

(25) While the invention has been described in complete detail and pictorially shown in the accompanying drawings, it is not to be limited to such details, since many changes and modifications may be made to the invention without departing from the spirit and scope thereof. Hence, it is described to cover any and all modifications and forms which may come within the language and scope of the appended claims.
