ABSTRACT:
A control arrangement is provided to control discharges of compressed gas into vessels containing difficult to unload material comprising one or more control valves connected in operative relation to discharge valves operative to discharge compressed gas from an accumulator into the vessel. The control valves are provided with a timer for controlling the time of discharge of compressed gas from the accumulator. This timer may comprise a pneumatic, electro-mechanism and/or electronic timer. The control arrangement may also include means for applying pressure gas to discharge valves which are in operative relation with accumulator discharge devices which are not being utilized for unloading. Various arrangements for mounting the accumulators, discharge valves, conduits, and discharge devices are illustrated in connection with a railway hopper car. Certain discharge device mounting arrangements are preferred in unloading certain types of lading.
