Abstract: The brake beams of a single axle railway car wheel truck are swingingly suspended from a body portion of the car and engage with the axle housings of the wheel and axle assembly to enable the brake beams to move laterally and longitudinally with the wheel and axle assembly when this assembly is forced to move with respect to the body portion of the car. Movement of the brake beams with the wheel and axle assembly enables the brake heads on the brake beams to be properly aligned with braking surfaces on the wheels under substantially all operating conditions of the wheel truck even though substantially all of the weight of the brake beam and actuator assemblies is borne by the body portion of the railway car.

Abstract: A brake cylinder lever on a railway car is supported in a substantially vertical orientation by a roller mounted on an inclined ramp to bias the brake system toward a "brake off" or nondrag condition.

Abstract: A sloped heat exchange element is sealingly mounted above the bottom of the tank of a railway tank car adjacent each end of the tank. Each heating element is thermally isolated from the tank cradles and bolsters, which detrimentally act as heat sinks in conventional heated tank cars. The sloped heat exchangers can be manufactured into the car or retrofit into tank cars not previously having heat coils or they can be retrofit into tank cars having either internal or external heating coils.

Abstract: The open end of a substantially cylindrical injection molded resilient plastic container, such as a paint pail, has a rim system integrally molded to the container wall to rigidify the open end of the container to facilitate filling the container using standard automatic filling equipment. An outer continuous rim and an inner discontinuous rim concentric with the outer rim are joined by a bridge member to form a substantially rigid rim system at the open end of the container.The rim system coacts with a closure lid to form a removable and resealable end closure on the container. Drainage or expulsion of fluid from between the inner and outer rims is provided for by drain openings or slots which make the inner rim discontinuous.

Abstract: In a railway hopper car with several bottom dump doors, the doors are operated by a main door operating member in the form of a thrust bar running the length of the car. The bar, when moved, rotates levers which rotate actuator shafts which move door operating linkage arrangements, opening and closing the dump doors. An adjustable positioning structure is provided on each lever to cause adjustment of the individual dump door positions. The adjustment is accomplished by tightening or loosening bolts in the adjustor, which is fixed on an actuator shaft running to the linkage arrangement. The adjustor and actuator shaft rotate on a bearing with respect to the lever, but are held in locked adjusted position by the adjustor bolts abutting on flanges welded to the lever.

Abstract: A water-cooled lance is supported above the mouth of a steel-making vessel for vertical reciprocating movement and includes a slurry pipe which is rotatably positioned to spray repair material against the inner lining of the vessel, or to place a new lining on the interior of the vessel.

Abstract: A lance for use in a basic oxygen vessel is provided with a fluid cooling arrangement which is mounted directly on the lance structure and which is vertically adjustable therewith to provide a fluid spray which effectively enables and ensures cooling and suppression of the exiting gas before it contacts the hood and moves into the ducts of the hood structure.

Abstract: A partition sheet structure for covered hopper railway cars providing for even fill of commodity between compartments. The structure facilitates the filling operation, and prevents buckling caused by the uneven fills of the cars, while allowing the partition sheet structures to act in its capacity as a structural member of the car.

Abstract: A trailer hitch for supporting wheeled trailers includes a pedestal which is rigidly secured to a platform and has mounted thereon for pivotal movement vertical support members which support a fifth wheel plate. The support members are interconnected by a horizontal plate which includes a horizontal pivot shaft and cushioning members which are placed in shear during transport of the wheeled trailers from one area to another.

Abstract: A modular center filler for railway vehicles comprising an inverted U-shaped core member fitted between front and rear cover plates and securely attached to a bottom cover plate to which a center plate is attached. Downwardly extending legs of the core are aligned with corresponding inner, beveled edges of the center plate which receive high forces during transit as a car rocks back and forth. The core member is positioned to receive these forces and transmit them into the center filler structure, car bolster and car body framing for even distribution throughout the vehicle.

Abstract: The subject invention relates to the corner construction of a railway car, wherein the end wall, vertical reinforcing plate, side wall corner post and side plate are arranged with associated parts in a manner permitting an assembly without rotation of the car during manufacture. The structure provided includes a rigid connector plate which is attached to the end wall and forms a sandwich type transition member for attaching a flanged end of the side wall sheet.

Abstract: The subject invention relates to the corner construction of a railway car, wherein the end wall, vertical reinforcing plate, side wall corner post and side plate are arranged with associated parts in a manner permitting an assembly without rotation of the car during manufacture.

Abstract: A product sampling apparatus for taking sponge iron sample pellets as they are moved by a conveyor from a direct ore reduction process includes upper and lower chambers, one of which is in communication with a sampling station, and the other which returns a portion of the sample to the conveyor. The apparatus includes a collector end desponed within the conveyer and includes a surface having deflectors baffles and openings which direct a typical representative portion of the product mix being sampled to the two chambers, one returning the portion to the conveyor and the other to the sampling station.

Abstract: A door locking mechanism for a hopper door includes a latch arrangement which is incorporated into a door closure mechanism activated by a side-of-track camming mechanism. The arrangement includes an actuating device responsive to car wheel engagement and a safety locking combination cooperating with the actuating mechanism.

Abstract: A welded structural frame for a railway car wall is disclosed as including a pair of aligned U-section vertical members welded to opposite sides of a U-section longitudinal member and a reinforcing insert welded between the sides of the longitudinal member in alignment with the vertical members to provide a frame substantially free of welding distortion. A method of making such a frame is also disclosed as including securing longitudinal and vertical members in a fixture, welding the vertical members to opposite sides of the longitudinal member and then welding a reinforcing insert between the sides of the longitudinal member in alignment with the vertical members.

Abstract: A trackside door closing arrangement for closing the swinging doors of a railway hopper car. This arrangement is self centering and shifts to counteract the cars lateral sway as it passes through the mechanism or shifts to accommodate cars that have parallelogramed during service.

Abstract: A covered railway hopper car includes a partition sheet assembly, including a plurality of partition sheets compartmentalizing the hopper car. The partion sheets include a construction at their upper end which relieves stress, reduces fatigue and improves partition sheet resistance to fatigue.

Abstract: A locking mechanism disposed on one of the panels of foldable doors utilized in railway cars for transporting vehicles for automatically connecting the panels together when in a collapsed position.

Abstract: The interior wall construction of a passenger railway car is provided with carpeted decorative panels which are fabricated before assembly with the interior wall construction. The attachment of the panels to the wall is provided by extrusions of rigid and resilient shape which permit the panels to be installed by snap-fit interengagement.

Abstract: A door locking mechanism for a railway hopper car includes a rotatable latch or rotor member engaging a keeper on the door for releasably locking the same. The latch member includes abutment faces which are engaged in locking position by a spring loaded lever. The lever includes a flat surface engaging a rounded cam surface on the rotor for positioning the same in a release position.
