Abstract: A well drilling assembly including a platform adapted to support a person while drilling a well therebeneath through an opening in the platform includes a clamp assembly carried by the platform and mounted for rotation with respect thereto. The clamp assembly includes a pair of open jaws disposed in confronting relatively movable relation and with respect to each other for engaging and for readily releasing a drilling stem so as to be able to support a column of drilling sections as new sections are added and also to permit the clamp to rotate while the drilling sections are rotated at a position supported by the clamp to hold the sections in spaced relation from the bottom of the hole being drilled. The method of drilling includes manipulations involved in supporting the sections of pipe spaced from the bottom of the drilled hole while flooding water through the pipe to flush out the opening and also to permit the pipe to be rotatably driven while so held without exerting manual lifting force on the pipe. The clamp assembly is readily released from the pipe so as to lower the sections into engagement with the bottom of the hole being drilled and the like.
