Abstract

A sleeve (10) comprises a cylindrical member (12) provided at one end (14) with a pair of opposing tapered peaks (16) and (18).
Peak (16) is higher (longer) than peak (18). Sleeve (10) is retained within a drive sub (26) of a ground drill and is constrained to move linearly along the drive sub (26). The peaks (16) and (18) cooperate with latch dogs (20) and (22) which are evenly spaced about and extend radially from a running tool (24). When the running tool (24) travels down the drive sub (26) and enters the sleeve (10), one of the latch dogs (20, 22) will strike one of the peaks (16) and (18) causing the tool (24) to rotate toward a predetermined rotational position.
Because the peaks (16) and (18) are at different heights, latch dogs (20) and (22) cannot simultaneously contact the very top of each peak (16) and (18). If latch dog (20) strikes the top of peak (16), it will then slide down one of the sides of that peak causing the tool (24) to rotate. The other latch dog (22) will then contact an opposite or most distant side of the peak (18). This ensures that latch dogs (20) and (22) cannot slide down adjacent sides of the peaks which would cause the tool (24) to jam.
