Abstract
A mud screen for installation between any two selected ends of interconnected pipes, such as a drill pipe string, comprises a supporting collar anchored in the selected threaded connection of the drill pipe string and a screen support mounted on such collar and secured thereto by one or more releasing devices. An apertured inverted conical screen is supported by the screen support in transverse relationship to the pipe bore. A bridging element is secured across the screen support and defines a mounting for an upstanding post which functions as a manual handle and also defines a fishing neck at its upper end for downhole retrieval.
