1. Drill string orienting apparatus comprising a nonrotating drill string with a down hole motor, a rotating bit sub below the motor and a bit on the rotating bit sub wherein the improvement comprises: an orienting device on said drill string adjacent said motor in nonrotating relation to the string, said orienting device having orienting means thereon projecting laterally from a side thereof to bear against the hole formation and bias the drill bit in a lateral direction opposite to that of the projecting orienting means, said orienting means being located below said down hole motor, and additional orienting means having means for locating it on the drill string above the down hole motor, said additional orienting means including means extending radially outwardly in a direction opposite to that of said first mentioned orienting means, and said additional orienting means being longitudinally movable within limits relative to the drill string to permit the drill string and drill to move vertically relative thereto.

3. Drill string orienting apparatus comprising a nonrotating drill string with a down hole motor, a rotating bit sub below the motor and a bit on the rotating bit wherein the improvement comprises: an orienting device on said drill string adjacent said motor in nonrotating relation to the string, said orienting device having orienting means thereon projecting laterally from a side thereof to bear against the hole formation and bias the drill bit in a lateral direction opposite to that of the projecting orienting means, said orienting means being located below said down hole motor, and additional orienting means having means for locating it on the drill string above the down hole motor, said additional orienting means including means extending radially outwardly in a direction opposite to that of said first mentioned orienting means, and said drill string having vertical external splines about a portion thereof adjacent said down hole motor, and said additional orienting means including a sleeve having internal splines complementary to those of the drill string and being movable vertically on said drill string into and out of engagement with said vertical external splines to permit rotational indexing of the additional orienting means relative to the first mentioned orienting means.

4. Drill string orienting apparatus for use on a nonrotating drill string with a down hole motor, wherein the improvement comprises: an orienting sleeve on a portion of the drill string adjacent the lower end thereof, said portion of said drill string having vertical external splines thereon, said orienting means including a sleeve having internal spLines, and said sleeve being vertically movable on said drill string to bring its splines into and out of engagement with the splines on said drill string portion, whereby said orienting means can be rotationally indexed relative to the drill string.

5. Drill string orienting apparatus comprising a nonrotating drill string having a down hole motor on the lower portion thereof, said down hole motor having a nonrotating lower bearing housing, a bit sub secured to and extending downwardly from said lower bearing housing, a drill bit connected to said motor through said bit sub for rotation with the motor, wherein the improvement comprises: a sleeve slidable upwardly on and connected to the bottom portion of said lower bearing housing and having orienting means projecting laterally from a side portion thereof to bear against the hole formation and bias the drill bit in a lateral direction opposite to that of the projecting orienting means.
