Abstract

A rotary railroad car F coupler assembly which employs a rotary connector between the yoke and car coupler, is described as having a yoke with a larger diameter opening in which a bigger rotary connector is mounted. The rotary connector, in turn, is designed to receive an AAR standard F coupler head with a heavier shank that has sidewalls, bordering the pinhole in the shank, which are thicker and have greater cross-sectional areas than similar sidewalls of shanks of AAR standard non-rotary type F car couplers. A pair of twin, parallel wearplates are provided between the top of the yoke and the adjacent housing. The top ridged portion of the yoke extends between these wearplates. In this way, the diameter of the yoke opening and the consequent cross-sectional area of the opening are increased. This enables a larger, sturdier coupler shank to be received in the aperture of the yoke while the overall coupler assembly may still be mounted in an AAR standard carsill.
