ABSTRACT OF THE DISCLOSURE A control arrangement is provided for controlling dis- charges of compressed gas to vessels containing difficult to unload material comprising one or more control valves connected in opera- tive relation to discharge valves operative to discharge compressed gas from an accumulator. The control valves are provided with a timer for controlling the time of discharge of compressed gas from the accumulator(s). 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 dis- charge devices are illustrated in connection with a railway hopper car. Certain discharge device-mounting arrangements are preferred in unloading certain types of lading.
