Patent ·
OSTI ID:5434975
This patent describes a locking and transfer system for use in well tools for shifting and locking co-axially arranged tubular members. It includes a tubular central actuating member adapted for coupling to a string of tubing for upward and downward movement by manipulation of the string of tubing; an outer first tubular member disposed on the central actuating member; a second tubular member disposed on the central actuating member between the central actuating member and the first tubular member; the outer first tubular member having inner and outer tubular parts defining an annular recess; the inner tubular part being disposed intermediate of the second tubular member and the central actuating member so that a portion of the second tubular member is slidably disposed in the annular recess; the inner tubular part having circumferentially arranged recesses and detent members in the recesses which are coupled to longitudinally extending spring members for radial movement relative to the inner tubular part; the central actuating member having a first annular locking recess for locking the detent members between a wall surface of the second tubular member and the first annular locking recess; and the second tubular member having an annular receiving recess longitudinally spaced from the first annular locking recess in the first longitudinal position of the central actuating member.
