Abstract: Catalytic converter emptying and filling device attachable to the housing of a catalytic converter containing means therein defining a bed for storing catalytic pellets and further having a port therein for emptying the pellets from the bed and housing. The device includes a rigid conduit connectable to the port for passing the pellets to a receptacle or cannister rigidly attached to the conduit for receiving the pellets from the converter and further including a vibrating instrumentality rigidly attached to the device for imparting vibrational turbulence not only to the rigid assembly making up the device but also to the converter housing and the pellets therein to cause the pellets to pass rapidly from the converter through the conduit to the receptacle or in the opposite direction.
