    Abstract: A drag trowel device having a plurality of leaves which contact the interior surfaces of a pipe coated with a lining substance to effect the trowelling of same. The leaves are mounted on one end of a longitudinal lever arm and a counterweight is mounted at its other end. The lever arm is pivotally connected at an intermediate location thereon to a pulling means. The counterweight serves to cancel the net weight of the trowel itself so that the trowelling pressure exerted by the leaves will be the same along the top and bottom of the pipe.

    Abstract: A drill rig having a universally mounted mast which is rigidly supported but moveable both transversely and rotationally in fore and aft and lateral directions. Novel mast support arrangements are disclosed including a free floating upper brace to accomodate relative vertical displacements of mast connection points which occur during rotational or tilting movements of the mast, and further including upper and lower crossbeams with connector elements separately moveable therealong and pivotally connected to the mast.
