Abstract
A circuit breaker with an anti-bounce mechanism characterized by separable contact means operable between open and closed positions and including a cross bar, an operating mechanism releasable to effect movement of the contacts and comprising a link connected to the cross bar, means for preventing bouncing of the cross bar when the contacts are open and comprising a stop member engageable with the length.
Claims5
A circuit breaker comprising:
- (a) stationary contact means;
- (b) movable contact means operable between open and closed positions of the stationary contact means;
- (c) contact arm means for supporting the movable contact means and pivotally mounted for movement of the contact between said position;
- (d) a cross bar operatively connected to the contact arm means and movable between first and second positions corresponding to the open and closed positions;
- (e) a circuit breaker operating mechanism releasable to effect movement of the contact arm means and comprising a link connected to the cross bar;
- (f) means for preventing bouncing of the cross bar from the first to the second position after moving to said first position and comprising a stop member;
- (g) the link having slot means through which the cross bar extends;
- (h) the link being movable to a more retracted position than the cross bar in the first position;
- (i) the link having a portion extending into the path of travel of the cross bar;
- and
- (j) and the link having a strike surface engageable with the stop member as the cross bar moves from the first to the second position when the link is in the fully retracted position so as to prevent the cross bar from bouncing back to the second position.
