Description

BACKGROUND OF THE INVENTION

This invention relates generally to a fastener driving tool, and more particularly to a socket for use by utility workers.

Utility workers (e.g., “linemen”) frequently carry out installation, maintenance, or repair on electrical transmission or distribution equipment in the field. This work involves removing and installing numerous shapes and sizes of fasteners and connections such as nuts, bolts, and threaded hooks and eyes.

There is a need for utility workers to have the appropriate tools available at hand while minimizing the number of separate tools to be transported and the likelihood of losing tools.

DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings wherein identical reference numerals denote the same elements throughout the various views, FIGS. 1-9 illustrate an exemplary socket tool 10.

The socket tool 10 is a unitary element with a body 12 extending between first and second ends 14, 16. For reference, a centerline 18 extends through the longitudinal axis of the socket tool 10. The socket tool 10 could be made by forging, casting, machining from solid stock or the like. It may be made from any material having suitable strength such as a metal alloy. Alternatively, plastics or composites could be employed depending on the specific end use.

In the illustrated example the body 12 is hollow with a central through-bore 20 (FIG. 7). Alternatively, it could be of solid construction. In this example the exterior surface is cylindrical. Other shapes such as polygons could be used.

A socket 22 is formed at the first end 14. The socket 22 is bounded by a peripheral wall 24 that terminates at an end face 26 oriented normal to the centerline 18. The interior of the socket 22 includes numerous surfaces which define structural elements for driving different kinds of fasteners. These structures may be referred to as “driving elements”.

One driving element is a pair of outer cross slots 28 that extend axially inward from the end face 26 and pass through the peripheral wall 24, bisecting the peripheral wall 24 into two sections. Each of the outer cross slots 28 is bounded by opposed, parallel side faces 30 which blend into a concave, arcuate bottom face 32. The bottom faces 32 are “angled”. More specifically, the bottom faces 32 are oriented at an acute angle to the centerline 18, such that the outboard edge 34 of each cross slot 28 is closer to the end face 26 than the inboard edge 36 of the cross slot 28. It is noted that the bottom faces 32 are bisected by inner cross slots, described below.

The outer cross slots 28 are useful for driving fasteners or objects extending in a transverse direction, such as T-handles. The angled orientation is also helpful in engaging rounded fasteners such as eye bolts and hooks.

Another driving element is an outer square drive recess 29 that is positioned adjacent the end face 26. This is defined by two opposed triangular slots 31 formed in the peripheral wall 24. Each triangular slot 31 terminates at a bottom face 33 that is oriented normal to the centerline 18.

The outer square drive recess 29 is useful for driving fasteners such as nuts and bolts. In one example, the outer square drive recess 29 can be sized for engaging and driving square nuts having outside dimensions of approximately 19 mm (¾ in.). It can also be used to drive fasteners such as hooks and eyes.

Another driving element is a pair of inner cross slots 37 that extend axially inward from the bottom faces 32 of the outer cross slots 28. Each of the inner cross slots 37 is bounded by opposed, parallel side faces 38 which blend into a concave, arcuate bottom face 40. The bottom faces 40 are “angled”. More specifically, the bottom faces 40 are oriented at an acute angle to the centerline 18, such that the outboard edge 42 of each inner cross slot 37 is closer to the end face 26 than the inboard edge 44 of the inner cross slot 37.

The inner cross slots 37 are useful for driving fasteners or objects extending in a transverse direction, such as T-handles. As illustrated, they may have a different width, e.g. narrower, than the outer cross slots 28. The angled orientation is also helpful in engaging rounded fasteners such as eye bolts and hooks.

Referring to FIG. 2, the second end 16 incorporates a square drive recess 46 positioned adjacent an end face 48. This is defined by four flat faces 50 arranged in two pairs of parallel faces. The square drive recess 16 adjoins the through-bore 20. One or more lock ball holes 52 may be formed in the faces 50. The square drive recess 46 is sized to accept the nose of a conventional driving tool such as a ratchet, drill-driver, or impact driver (not shown).

The socket tool 10 as described herein as the advantage of providing a portable, compact driving tool for multiple sizes of fasteners all in one tool. This is more convenient than carrying multiple tools and greatly reduces the chances of one or more tools being lost.

The foregoing has described a socket tool. All of the features disclosed in this specification (including any accompanying claims, abstract and drawings), and/or all of the steps of any method or process so disclosed, may be combined in any combination, except combinations where at least some of such features and/or steps are mutually exclusive.
