<p>A hatch cover arrangement for a railroad car or the like and method of making the same as well as a railroad car utilizing such hatch cover arrangement are provided herein. The hatch cover arrangement comprises the combination of a hatch cover and a holddown bar for the hatch cover. The holddown bar has opposed ends, one of which is adapted to be pivotally mounted to the car and the other of which is adapted to be releasably latched to the car, while a medial portion thereof intermediate the opposed ends thereof extends transversely across the hatch cover. The holddown bar and the hatch cover are made of a one-piece homogeneous member formed of polymeric material. Thus, the hatch cover for a railroad car could be made integral with one or more of the holddown bars for that hatch cover and the holddown bar would be a one-piece homogeneous member formed of polymeric material and would thereby not require separate operating parts of the hatch cover and the holddown bars therefor.</p> |
