<p>Releasably removable and adjustable polarizing means (30) for mateable assemblies (10,20) and comprising a keyway (72) disposed in one assembly and a polarizing pin (40) mounted in a slotted bore disposed in the other assembly, the pin having a roud base (42) and a polarizing key (52) extending axially from the base, the base being provided with a plurality of longitudinally disposed projections (50) extending radially therefrom. A transverse cross-section of the slotted bore is somewhat smaller than the transverse cross-section of the base so as to provide a tight interference fitment therebetween. Another embodiment includes the one assembly having a like slotted bore and provides a multisided insert (60) having the keyway disposed therein, the insert and base being interchangeably fitable within the slotted bore of either assembly (10,20).</p> |
