Abstract: A reflective warning device for warning oncoming traffic of a stalled vehicle in a road, having a supporting member attachable to a stalled vehicle to extend outwardly there from when the device is attached to the vehicle, and a cylindrical display element mounted on the supporting member and having a reflective surface facing oncoming traffic to indicate the presence of a stalled vehicle to oncoming traffic. The device is storable conveniently in a vehicle for use when needed should an emergency arise.

Abstract: A hold down bar for securing adjacent hatch covers of a hopper car and for further sealing the gap that exists between those covers includes a latch arm formed from spring steel in the configuration of an inverted U so as to have a generally straight midportion and legs which are directed downwardly and outwardly from the midportion. In addition, the bar has a resilient shoe which fits against and is attached to the midportion of the latch arm, but is shorter than the space between the two legs so that it can be adjusted back and forth in that space and thus positioned with considerable precision with regard to underlying hatch covers. The shoe in turn carries a gasket that seats against the adjacent hatch covers along a gap between them to effect a water tight seal with those latch covers. Being formed from spring steel, the latch arm will deflect in the presence of heavy impacts, such as derived from the latch covers being dropped on them, but will not take on a permanent deformation.
