Abstract
1463068 Hopper wagons S WHITE 23 Sept 1974 [24 Sept 1973] 44726/73 Heading B7L [Also in Division B8S] A railway hopper wagon or storage silo has a bottom opening closed by two doors 32, 34 pivotally mounted on stub axles 40, the doors being opened and closed by a common operating mechanism arranged so that if one door reaches its closed position before the other door, said mechanism may still be operated to close said other door. The operating mechanism comprises a lever 46 pivotally attached to the door 34 and to a drag link 70, the latter being connected to a trunnion 68 movable along a screw 50. A link 52 is pivotally connected to the door 32 and to the lever 46. Hand wheel 72 or 78 may be turned to rotate screw 50 and operate the doors. As shown in dotted outline, the lever 46 may be attached to door 34 through an intermediate link 48. A double latch 92 engages pins 96 on plates 42 supporting the doors. The latch may be released by manual means (104), Fig. 4 (not shown). Door 32 carries a rigid member 80, Fig. 7, co-operating with a sealing strip 86 resiliently mounted on the lower end of lever 46. The wagon may be divided by a transverse partition and two doors mounted beneath each compartment, the operating mechanisms being mounted in the transverse partition.
