Abstract
Abstract A kickover tool in which the body and actuator are formed of two elongate members having flat sides held in sliding confronting relationship with a tool, carrying arm connected thereto and moved between retracted and extended position in response to relative movement between the body and actuator. A locator key is provided which has spring means urging the key to extended position which is rendered ineffective by relative movement between the body and actuator and then either the same spring or another spring is effective to urge the key towards retracted position.
