摘要： A double hinge locking system mounts and secures a series of two-way opening covers or similar members. Each hinge/lock component of the system provides a combination hinge pivot and associated lock that operate on a common axis, and includes a locking device in which fixed and rotary locking parts are presented by fixed and movable saddles coaxial with the hinge axis and relatively rotatable about such axis between locked and unlocked conditions. An interlock mechanism interconnects locking devices on opposite sides of the hinged member to prevent double unlocking. Additionally, a passive safety lock is provided by the cooperating saddles to prevent separation of the member from its mounts in the event that double unlocking inadvertently occurs.

摘要： A hopper car gate for discharging cargo from a hopper car having a length greater than its width. The gate has opposed generally upright side walls and opposed generally upright end walls coupled with the side walls. The coupled walls present a top opening and a bottom opening. A first rail extends between and is coupled with the side walls adjacent the bottom opening. A first door is supported on the first rail and is moveable in a direction that is perpendicular to the length of the hopper car that the gate is joined with between a closed position which blocks the bottom opening and an open position which allows cargo to exit through the bottom opening.

摘要： A hopper car having an increased volume. The car has side walls, end walls, a bottom, and first and second sloping surfaces. The bottom lies at least partially in a horizontal plane and includes a plurality of spaced apart openings. The side walls, end walls, and horizontal plane define a volume X. The first and second sloping surfaces are located between adjacent openings and joined to the bottom adjacent the openings. The sloping surfaces extend upwardly from the bottom to present an inverted V enclosing a volume Y. The volume Y is no more than approximately 1 to 5% of the volume X.

摘要： A railroad hopper car discharge gate is assembled from unitary stacked frames that provide unimpeded flow of lading during discharge. A low-wear glide system minimizes friction between the gate panels and other components of the apparatus, and an improved sealing system protects lading from contaminants such as rain, dust and insect infestation and provides enhanced vacuum sealing for greater efficiency during vacuum discharge.

摘要： A drive system for a railway hopper car discharge gate includes a door panel operated by a rack and pinion drive. The pinion teeth present a substantially cylindrical profile in a plane orthogonal to the axis of pinion rotation. The cylindrical tooth profile substantially prevents the pinion teeth from skipping or walking against the rack teeth when the spacing between the pinion and the door panel and associated rack fluctuates during operation of the discharge gate. Pinion torque is converted into a vertical force at the ends of travel of the door panel to prevent damage to the drive components. A bearing arrangement supports a drive shaft that is operated to rotate the pinions, and minimizes deflection of the shaft when under rotational load. An inertia brake is provided to engage the door panel and prevent it from opening upon a rapid stop of the hopper car as may occur upon impact with an adjacent railway car.

摘要： A panel system includes a first skin, a second skin, a web core constructed from sheet material for securing the skins together in a spaced, sandwich relationship, and a connecting means for affixing the web core within the skins. The web core includes a plurality of spaced apart longitudinal members having longitudinally spaced projections extending therefrom and further having transversely aligned, longitudinally spaced slots therein. The web core further includes a plurality of spaced-apart, transverse cross members each having spaced slots therein receiving the longitudinal members at corresponding transversely aligned slots thereof to provide an interlocked grid work between the first and second skins. The grid is connected to the skins utilizing the projections, which extend through slits in the skins in one embodiment to facilitate welding or otherwise bonding the components. In a second embodiment the projections present mounting ears that receive fasteners that extend through the skins.

摘要： A paneling system includes a first upper or outer plate having a plurality of outwardly extending tabs unitarily and integrally formed therewith and a second, lower plate spaced apart from the upper plate to present a void therebetween. The tabs span the void and join with the second plate to fixedly secure the plates together to form the panel construction. The free ends of the tabs may be welded within slots formed in the second plate to secure the plates together. Alternatively, the tabs may be L-shaped to present a flange in parallel relation to the plates. The flanges are welded to the second plate to secure the plates together. The tabs may present anchor holes in the first plate for securing a load in place. The first plate may include a raised portion at the periphery of the anchor holes to help prevent skidding. A third plate may be included spaced apart from the first plate to form a void therebetween with the first plate having tabs secured to the second and third plates to form the panel construction.

摘要： A hatch cover assembly for railcars. The assembly includes a series of hatch covers aligned end to end to cover an opening in a railcar. Each of the hatch covers has an overlapping end section which seats upon an adjacent cover to provide a seal. The end of each hatch cover having this overlap is common such that the covers may be opened sequentially from one end of the railcar to the other without requiring the operator to backtrack. The overlapping section may be formed as a separate element mounted upon the cover. The overlapping element can be mounted for movement between a closed position in which it overlaps the adjacent cover, and an open position in which it is spaced from the adjacent cover. The covers may additionally or alternatively be connected together such that the opening of a cover assists in the opening of an adjacent cover. The covers may be connected by a mechanism, such as a cable or a shaft, such that as the first cover falls completely open from a vertical, partially opened condition, it is fixed to the adjacent cover. This will result in the weight of the first cover assisting in the lifting of the adjacent cover to the vertical, partially opened condition.

摘要： Apparatus for enclosing open end portions of railway hopper cars in order to reduce the aerodynamic drag. Each corner area of each end is provided with a shroud which includes a side plate and an end plate. The side plate covers the open side area at the end of the car and also covers the first vertical rib on the car side. The end plate covers the part of the end of the car adjacent the corner. Each shroud is shaped in an aerodynamically efficient configuration to minimize air resistance.
