Abstract
A catchment mechanism for an electrical switching apparatus operating mechanism is provided. The catchment mechanism includes a catchment wheel with a radially extending surface, a catchment prop, and a catchment prop reset pin. The catchment wheel rotates with the cam in the closing assembly as the closing springs are being charged. During the charging of the springs, the catchment prop stop edge travels over, but preferably does not engage, the wheel outer surface. When the closing springs are released, the catchment prop stop edge engages the catchment wheel radially extending surface thus causing the catchment wheel to stop rotating. As the catchment wheel is fixed to the cam shaft, the rotation of the cam shaft, and therefore the cam, is also stopped. The catchment wheel radially extending surface is positioned so that the cam is stopped in an appropriate position to begin recharging the closing spring.
