Abstract
A method and apparatus for controlling a force applied to a pantograph. A bidirectional snubber and a velocity controller are used to dampen the applied force. Linkages between a shaft and the bidirectional snubber and between the bidirectional snubber and the velocity controller are used to rotationally translate the applied force.
Claims20
A method of controlling a mechanism operated contact assembly comprising the steps of:
- rotating a main shaft operable between an open and a closed position;
- coupling a bidirectional snubber member (BDS) to the main shaft for controlling a force applied to a pantograph, the BDS having a opening spring and a closing spring;
- storing energy by compressing one of the springs;
- discharging energy from the compressed spring;
- and
- applying a force to the pantograph so as open a switch.

An apparatus for controlling a mechanism operated contact assembly comprising;
- a rotatable main shaft operable between an open and a closed position;
- a bidirectional snubber member (BDS) coupled to the main shaft for controlling a force applied to a pantograph, the BDS having an opening spring and a closing spring;
- and
- a first means for linking the rotatable main shaft with the BDS.
