Abstract: This invention concerns a process and apparatus for filtering slurries and efficiently washing the filter cake. More specifically, the invention provides for mechanically raking the surface of the filter cake to loosen particles therefrom. The loosened particles are entrained by a wash liquid or other fluid applied subsequent to the raking step; the entrained particles tend to occlude cracks in the filter cake, thereby eliminating preferential fluid flow through such cracks.

Abstract: A bottom door discharge mechanism for a railway hopper car includes a bell crank arm for each of the doors located in pairs at the bottom of the hopper. The arms are tripped from track side cams on opposite sides of the car for movement to open and closed positions. A safety locking mechanism is provided which during transit positively locks the arms against rotation to an open position. The locking mechanism includes arms or cam followers which are actuated from the track side opening cam thereby disengaging said locking mechanisms just prior to engagement of a second cam follower with said track side cam whereupon the bell crank levers are actuated to move the doors to their open position.

Abstract: A railway car door arrangement is provided with a lock mechanism positioned toward the upper ends of the doors so as to be remote from the track level and thus will discourage pilferage. The mechanism includes a hasp which is pivotally mounted for swinging movement on a projecting portion of a door and which is engageable with a keeper socket supported either on an adjacent door, in the case of a two-door arrangement, or on the door frame of the box car side wall. The keeper includes a socket for receiving an end portion of a hasp and suitable locking projections are adapted to receive a cable or lock for further locking the hasp in closed position.

Abstract: A sliding door includes a roller lifting mechanism provided by horizontally spaced bell cranks to which rollers are connected and which may be pivoted downwardly to engage a door track for raising the door so that it may be laterally moved to one side of the door opening. The lifting mechanism includes a cam element which is manually rotated to exert a push force on the bell crank levers for pivoting the same into the lift position. A modified version of the lift mechanism includes a linkage arrangement which exerts a pulling action on the bell cranks for achieving the lifting function.

Abstract: A chassis-to-container locking arrangement includes a housing defined by the lateral end extensions of the chassis bolster member thereby providing coupling assemblies at the four corners thereof.
