摘要

A bi-directionally openable hatch cover hinge and lock device for hatch covers which close the hatches on top of railroad cars and which are openable from either side of the car, utilizing a minimum number of component parts and including a passive captive device for the hatch cover to prevent loss of the cover if the latches on one side are left open and the hatch is opened from the other side, and also including an integrated one piece yoke top and handle with a pivoted cam lock attached to the handle, the pivoted cam lock being weight biased toward its locked position and being prevented from rotating beyond its weight biased locking condition by a stop pin.
