Abstract
A railcar coupler may include a coupler head comprising a shank and a head portion, the head portion defining a cavity for receiving a knuckle, a thrower, and a lock. The cavity can include a top pulling lug, a bottom pulling lug, and a thrower retaining lug. The top pulling lug can be configured to engage an upper knuckle pulling lug, and the bottom pulling lug being can be configured to engage a lower knuckle pulling lug. During operation of the railcar coupler, the ratio of the stress between the top pulling lug and the bottom pulling lug can be configured to be better balanced to help extend the life of the railcar coupler assembly.
