Abstract
An apparatus for mounting an attachment structure (such as an EOT) to a railroad coupler includes a base, a locking member (J-hook), a bolt and one or more spring elements. The base includes a mounting portion for the attachment structure and a sleeve insertable through the attachment structure. The base, the J-hook and the bolt cooperate such that the J-hook is rotated from an unlocked position to a locked position by torque applied via the bolt head. Consequently, the J-hook shaft is pulled inside the sleeve and the J-hook aligns with a clamp face of the base to clamp a portion of the coupler therebetween. Responsive to the applied torque, the one or more spring elements are compressed to allow mechanical engagement between a first surface and a second surface, producing a mechanical torque opposing the applied torque, which reduces axial forces on the J-hook.
