摘要： A sliding gate for closing the discharge opening of a hopper having inclined side walls is mounted on elongated low-friction bodies or assemblies secured between the underside of upturned inclined side margins of the gate and the top sides of inclined side walls of a discharge chute secured to the hopper and extending below the discharge opening. The elongated low-friction bodies or assemblies are mounted to create a labyrinth seal by methods which include the use of a plurality of integral stud portions extending through corresponding openings along the inclined side margins of the gate, adhesives, keyways, welding or combinations thereof. The elongated low-friction bodies or assemblies are of a polymeric material such as nylon, Teflon or a composite material like ultra-high molecular weight polyethylene impregnated with molybdenum disulfide. The polymeric low-friction material may be molded to a metal matrix which is mounted on the gate by means of welding. Tapered sealing flaps for engagement with the lower portions of the inclined side walls of the hopper may be included in the low-friction bodies or assemblies.

摘要： A door driver is provided on a railway house car for moving a railway car door between a locking position and a sliding position. The door driver includes a lever which is rotatably mounted on a structural member of the railway car. The door driver further includes a plurality of drivingly interconnected drive members, one of which is a driving member and another of which a driven member. The lever is drivingly connected to the driving member. The drive members have a plurality of gear teeth thereon and are rotatably mounted on the railway car with the gear teeth of at least one other drive member. When a force is exerted on the driving member, the driving member transmits that force to the driven member so the force capable of being exerted by the driven member is greater than the force exerted on the driving member. The door driver also includes means for connecting the railway car door to the driven member so that upon movement of the lever, the railway car door is urged between the sliding position and the locking position with a force that is greater than the force exerted on the lever.
