KICKOVER TOOL Abstract of the Disclosure 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. This invention relates to kickover tools. In the past, many different kickover tools have been devised for landing and retrieving valves from side pocket mandrels. While the tools have taken many different forms, they have generally been characterized by having a telescoping relationship between the body of the tool and the actuator of the tool and by a key on the actuator which engaged a shoulder in the well and which was rendered ineffective after the tool had been kicked over by shearing of a pin. When pulling a valve, a substantial force may be required and various provisions have been made to keep the kickover arm in the kickover position while pulling a valve from the valve pocket of the mandrel. Many of these tools have been successful and are in operation today. However, they are all complex and usually fragile at one or more points.
