Abstract

A power chain saw utility tool provides an apparatus for effecting mechanical repairs and/or adjustments to a power chain saw having a chain bar. In one presently preferred embodiment, the power chain saw utility tool comprises a first elongated cylindrical case member that defines an elongated interior compartment having a transverse cross section with a non-circular shape into which a slide member is received. The slide member in this embodiment includes a plurality of interleaved members pivotally attached at one end thereof and comprising tools adaptable for making minor repairs and/or adjustments to the power chain saw. The slide member is selectively pivotable about the open end of the elongated cylindrical case member. When fully retracted, however, the slide member is received entirely within the elongated cylindrical case member. The elongated cylindrical case member, furthermore, has a closed end opposite to the open end, said closed end comprising a socket configured with a shape to receive, for example, a nut that secures the housing assembly of the chain bar of the power chain saw.

10. An apparatus as in claim 9, further comprising:

a plurality of storage tunnels open at one end and defined at least partially along the length of said elongated case member;

a plurality of detachable tools, each said detachable tool being configured to be slidably received within one of said storage tunnels, one of said detachable tools comprising a flat head screw driver having a blade of a size to fit a screw head on the power chain saw, another of said detachable tools comprising a pair of tweezers; and

wherein each of said plurality of interleaved members is pivotally attached at said one end of said slide member, one of said interleaved members comprises a flat head screwdriver having a blade of a size appropriate to adjust the adjustment mechanism for regulating the tension applied by the chain bar to the chain of the power chain saw, another of said interleaved members comprises a torques driver, yet another of said interleaved members comprises a knife blade, still another of said interleaved members comprises a wire tool for cleaning oil from the oil hole of the power chain saw and having a blunt edge wherein at least a portion of the transverse width of said blunt edge is of a size approximately equal to the spark plug gap of the spark plug employed in the power chain saw, a file for cleaning the spark plug point of the spark plug employed in the power chain saw, and an elongated cleaning tool having a scooped end configured for cleaning the chain bar groove of the power chain saw.

19. An apparatus as in claim 10, further comprising:

three walls cooperating to define a first slot in said end face of said second end of said case member, said first slot defining an end opening to said interior compartment, said first slot being configured to permit passage of said slide member, two of said three walls being disposed in opposition and defining the width of said first slot, the third of said three walls defining a back wall disposed transversely to said two walls defining said width, said back wall being configured to be flush with and to restrain said slide member so that said slide member, when maximally extracted from said case member, may pivot only in a forward direction; and
