T-handle wrench kit

A wrench kit comprising a wrench adapted to apply rotational force to a square or hexagonal fastener having parallel surfaces, said kit comprised of:

• 1) a wrench member comprised of:
• a) a shaft elongated upon a longitudinal axis between proximal and distal extremities and having a bore penetrating said shaft adjacent said proximal extremity in orthogonal relationship to said longitudinal axis,
• b) an operational block having a rear extremity associated with the distal extremity of said shaft, a forward extremity defined by a panel orthogonally disposed to said axis and bounded in part by a rearward surface and a flat forward surface bifurcated by a receiving groove containing a central aperture, and a cylindrical channel coaxially aligned with said longitudinal axis and communicating with said forward surface,
• c) retaining means adapted to reciprocate within said channel and urged by a coil spring toward said forward surface, said retaining means having a forward end configured to penetrate said aperture,
• d) a flat plate affixed to said forward surface and thereby covering said groove in a manner to create a passage of rectangular configuration, and
• e) a straight handle held by said bore, and
• 2) a plurality of heads, each having a working extremity equipped with fixed parallel jaws adapted to engage the parallel surfaces of said fastener in close conformity therewith, an elongated mounting extremity adapted to slidably engage said passage and having a locking recess adapted to be engaged by the forward end of said retaining means, and a shoulder adapted to abut said block.
