Abstract
Apparatus for use in conjunction with a drilling rig for catching and saving mud or the like from inside of a drilling rig pipe or drill string, comprised of one to three sections of pipe or stands connected together at connection junctures, of the type having a drill bit at the bottom thereof for use when the drill string is in the process of being pulled up out of a hole drilled in the ground. When each topmost stand of pipe is disconnected from the adjacent lower stand of pipe at a connection juncture, one stand of pipe is disconnected from the adjacent lower stand of pipe at the topmost connection juncture. A pair of doors are provided on one side on the container for opening the container on one side. A closing mechanism is attached to the container for automatically closing the container when the container is positioned at one side thereof against the pipe whereby the force of the closing mechanism against the pipe will cause the container to close. A latch is attached to the other side of the container for locking the container in a closed position in sealing engagement with the pipe around the topmost connection juncture. A drain is disposed in the lower part of the container for emptying mud from the container after the topmost stand of pipe has been disconnected.
