ABSTRACT:
A well valve handling apparatus or kickover tool for placing a valve in or removing a valve from an offset sidepocket in a mandrel in a well tubing and having a support body, a shifting tool pivotally supported from the support body with spring means yieldably urging the shifting tool towards the sidepocket by acting against a spring base initially positioned to engage one end of the spring. After use, the base is moved out of engagement with the spring for allowing the shifting tool to pivot towards alignment with the support body. A movable body having first and second parts is carried by the support body and a shear pin initially holds the two parts together and the support body includes an opening of a smaller size than the shear pin on one side aligned with the shear pin for aiding the removal of the pin when sheared, and the support body includes an opening for inserting the shear pin on the other side aligned with the shear pin whereby the shear pin may be installed and removed without disassembling the apparatus. The valve handling support is pivotally connected to the shifting tool, and the shifting tool includes a spring-loaded detent between the shifting tool and each of the pivot connections to the support body and valve handling support for allowing greater lateral shifting movement of the valve handling support.
