Method and apparatus for aligning and affixing portions of circuit breaker apparatus

摘要

A washer is disposed axially on a bolt between two portions which are to be secured by the bolt. The portions have holes or openings therein, which are larger than the diameter of the bolt for providing a range alignment between the portions and the bolt. The washer has a sharp circumferential lip edge on each side thereof which is generally parallel to the axis of the bolt. The edges protrude into the respective portions once the bolt has been axially tightened to thereby secure the portions in a predetermined disposition relative to each other. Lateral movement of the portions relative to each other is thus prevented or reduced.
