ABSTRACT:
An improved anchor positioner for use with anchors incorporated in a liner or casing of a well bore. The anchor positioner comprises upward-facing spring arms having downward facing shoulders on the exterior thereof, the spring arms, when extended radially outward, engaging a shoulder on an anchor to locate a tool string in a well bore. An indexing head, rotatable in response to axial reciprocation of the tool string, retracts the spring arms from the anchor. A subsequent reciprocation of the tool string will cause the spring arms to extend radially outward and to be locked in the extended position by contact with the indexing head, thus locking them into the anchor against downward movement. Retraction of the spring arms is effected by force from contact with inwardly-inclined faces on the indexing head, and extension of the spring arms is effected by outward force exerted by contact of the inside of the spring arms with axial grooves on the outside of the indexing head. Rotation of the indexing head and therefore change of radial alignment is effected through a pin and slot mechanism.
