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.
