B61G 3/04 - Couplings comprising mating parts of similar shape or form which can be coupled without the use of any additional element or elements with coupling head having a guard arm on one side and a knuckle with angularly-disposed nose and tail portions pivoted to the other side thereof, the nose of the knuckle being the coupling part, and means to lock the knuckle in coupling position, e.g. "A.A.R." or "Janney" type
A method for manufacturing a railcar coupler knuckle includes providing a first mold section having internal walls defining at least in part perimeter boundaries of a first coupler knuckle mold cavity. The method includes providing a second mold section having internal walls defining at least in part perimeter boundaries of a second coupler knuckle mold cavity. The second coupler mold cavity of the second mold section is offset from the first coupler mold cavity of the first mold section. The method includes closing the first and second mold sections and at least partially filling the first and second coupler knuckle mold cavities with a molten alloy, the molten alloy solidifying after filling to form the coupler knuckle.
