Abstract

A rotary railroad car coupler assembly is described as having a unique carrier which is designed for limited angling or tilting in the vertically elongated chamber of the striker, as the coupler rotates. The projecting lugs of the carrier which interlockingly engage the stops in the chamber of the striker, have sloping sides which diverge from the sidewalls of the chamber in a direction away from the coupler, rather than being parallel to the sidewalls as are the sides of the lugs of AAR Standard carriers. This improvement eliminates chattering that is normally occasioned when AAR Standard carriers are used in connection with a rotary railroad car coupler assembly and helps to prevent undue stress of the striker caused when the carrier becomes momentarily frozen or bound up in the striker as the coupler rotates.
