CA 2196382

A mechanical set anchor wherein a plunger extending from a base end of an anchor body activates a pin type trigger which releases a spring utilized to set multiple slips extending from the body of the anchor. Continued downward compressive forces fully sets the slips into the borehole pipe casing. The slips are maintained in their fully set position by a locking nut. Means are additionally provided to further set the slips into the pipe casing after slips are released from the anchor body. The anchor is mechanically released by an upward pull under tension of sufficient strength to shear release pins that release the compressed spring fully retracting the slips within the anchor body so that the anchor may be tripped from the borehole without interference from the previously engaged slips.
