US Patent:

42600464, Apr 7, 1981

Filed:

Oct 27, 1979

Appl. No.:

6/084513

Inventors:

Robert F. Seitz - Mentor OH

Assignee:

The Youngstown Steel Door Company - Cleveland OH

International Classification:

F16D 6702

US Classification:

192 8R

Abstract:

A rail car having an interior cavity and an end opening for loading and unloading lading is provided with a pair of door assemblies, each of which includes a plurality of panels, each pivotally movable with respect to the other for closing at least a portion of the end opening. Pivot means comprising a shaft for mounting each of the door assemblies are provided to move the door assemblies between their respective open position and closed position. The pivot means are mounted for movement toward and away from the interior of the rail car on a track to permit storage of the door assemblies within the rail car when their panels are folded back upon one another. The shaft is manually driven by means of a housing. A rack and a source of rotational power including a cooperating pinion mounted on the shaft act to guide, move and lock the door. The housing has a cavity into which one or more enlarged lever ends are inserted and secured before assembly of the housing to the shaft.

Appl. No.:

6/180864

Inventors:

Robert F. Seitz - Mentor OH

Assignee:

The Youngstown Steel Door Company - Cleveland OH

International Classification:

E05D 1510

US Classification:

49220

Abstract:

A railway house car has plug doors, each with a pair of rotationally driven top operating cranks and an auxiliary crank in engagement with a c-shaped top retainer. The auxiliary crank is mounted between the operating cranks on a lower vertical crank end for rotation relative to the door. An upper vertical crank end of the auxiliary cranks has mounted thereon a front sled moveably engaging the inner surface of the downwardly extending front flange of the top retainer and a bottom sled moveably engaging the upper surface of the laterally outwardly extending lower flange of the top retainer. The bottom sled and lower flange extend outwardly beyond the front sled and front flange to resist the auxiliary crank's outward pivotal movement and separation from the retainer and any door displacement as a result. The sleds provide large load bearing surface areas to resist distortion and are spaced and mounted on the common vertical axis of the upper vertical crank end for rotation independent of each other.
