Abstract:
A core assembly for casting a railcar coupler knuckle includes a first core and a second core. The first core includes a lug. A slot is defined in the second core. First and second positive stop surfaces are provided. The invention reduces core shifting during casting and therefore improves the strength and fatigue life of a coupler knuckle.
