With reference now to the drawings, and in particular to FIGS. 1 to 11 thereof, a new and improved adjustable socket apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
More specifically, the adjustable socket apparatus 10 of the instant invention essentially comprises a hexagonal parallelepiped main body 11, to include an upper body 12 coaxially aligned with the upper body 12 formed of a cylindrical configuration. It should be further noted, however, that the main body 11 may also be formed of a cylindrical configuration coextensive with that of the upper body 12 as the parallelepiped main body 11 is arranged to provide for wrench flats in accommodating a wrench structure for securement thereto. A square section bore 13 is concentric with and coextensive with the upper body 12 to receive a square drive member (not shown) of conventional construction.
A respective first, second, and third hexagonal tubular sleeve 14, 15, and 16 are mounted within the main body 11 and are each formed of a predetermined height less than a main body height defined by the main body. Each sleeve is arranged in concentric alignment relative to one another in a first position and are maintained in a coaxially aligned relationship in a displaced second position, such as illustrated in FIG. 6, when displaced from the first position, such as illustrated in FIG. 5. The main body and upper body, as well as the sleeves, are defined about a central axis 11a.
The main body 11 includes a main body cavity 17 coaxially aligned with the central axis 11a and formed with a main body lower terminal end 19. A main body shoulder 18 extends into the cavity 17 from the lower terminal end 19 a predetermined first spacing. A first sleeve outer projection 20 is formed exteriorly of the first sleeve 14 and is formed a first spacing from a lower terminal end of the first sleeve to be received on the main body shoulder 18 to prevent projection of the first sleeve beyond the lower terminal end 19. A first inner projection 21 is spaced from the lower terminal end 19 a second spacing and cooperates with a second sleeve outer projection 22 spaced from the lower terminal end 19 a second spacing. A second sleeve inner projection 23 is formed to an inner surface of the second sleeve and spaced from the lower terminal end 19 a third spacing cooperating with the third sleeve outer projection 34 spaced from the lower terminal end the third spacing to maintain the sleeves in a concentric alignment in the first position, as illustrated in FIG. 6. The cavity 17 is defined by the main body lower terminal end and by a main body cavity roof 25 at an upper terminal end within the main body 11, wherein the roof 25 is orthogonally oriented relative to the axis 11a. The roof includes a plurality of concentric grooves coaxially aligned about the central axis 11a defined by a first groove positioned in alignment above the first sleeve 14, a second groove aligned and above the second sleeve 15, and a third groove aligned and positioned above the third sleeve 16.
