<p>"WELL DRILL PIPE SUPPORT" An adjustable vise support is engaged over the upper end of the well casing with the drill pipe string extending freely therethrough and into the well bore. When it is desired to support the drill pipe string for attaching or detaching additional lengths of drill pipe, the movable jaw is adjusted and swung closed whereupon the coupling between adjacent lengths of drill pipe, engages the upper sides of the jaws by the lower end thereof thereby supporting the drill string so that the uppermost pipe length can be attached or detached. The movable jaw is readily swung clear when the uppermost length of the pipe has been attached or detached from the drill string and drilling and/or withdrawing of the drill string can continue.</p>
