ABSTRACT:
A linkage for coupling to at least one rotatable shaft of a high voltage circuit breaker has an elongated body having a central body portion and opposed end portions. At least one of the end portions comprises a pair of parallel side walls and a bottom wall extending longitudinally from the central body portion along the end portion. Each of the parallel side walls comprises an outer side wall portion and an inner side wall portion. Each outer side wall portion extends longitudinally beyond an outer end of a lower part of the inner side wall portion and an outer end of the bottom wall. The parallel side walls and bottom wall form a slot having an open end adapted to receive a square or rectangular end of a rotatable shaft in the slot. The slot has an upper longitudinal opening between the adjacent upper edges of the side walls and a lower longitudinal opening between adjacent lower edges of the outer side wall portions that extend beyond the bottom wall. A plurality of connectors is provided for clamping the parallel side walls against the end of the rotatable shaft to secure the rotatable shaft in the slot.
