Kickover tool

Claim 2

A kickover tool comprising, stem means adapted to be run in a tubing, tool carrier means pivotally mounted on the stem means and releasably latched in a first position for running and pivotal to a second position for setting or pulling a tool, dog mandrel means having dog means thereon and slidably mounted on the stem for movement between three positions to control operation of the kickover tool, means maintaining the dog means extended in the first and second positions and permitting retraction of said dog means in said third position, means releasing said latch to permit pivoting of said tool carrier means upon movement of said dog mandrel means from said first to said second positions and relatching said tool carrier means in said second position when the tool carrier means reaches said second position, said releasing means releasing said latch upon movement of said dog mandrel means from said second to said third position, and means yieldably resisting movement of said dog mandrel means from said first to said second position and from said second to said third positions.

Claim 3

The kickover tool of claim 1 wherein the yieldable means is provided by a pair of spaced stop rings carried on the stem means by shear pins.

Claim 4

A kickover tool comprising, stem means adapted to be run in a tubing, tool carrier means pivotally mounted on the stem means and releasably latched in a first position for running and pivotal to a second position for setting or pulling of a tool, dog mandrel means having dog means thereon and slidably mounted on the stem for movement between four positions to control operation of the kickover tool, means maintaining said dog means extended in said first and second positions and permitting retracting of said dog means in said third and fourth positions, means releasing said latch to permit pivoting of said tool carrier means upon movement to said dog mandrel means from said first to said second position and relatching said tool carrier means in said seecond position when the tool carrier means reaches said second position; said releasing means releasing said latch upon movement of said dog mandrel means from said second to said third position, means yieldably resisting movement of said dog mandrel means from said first to said second position and from said second to said third position, and resilient means biasing said dog mandrel means toward movement from said first to said second positions and from said second to said third positions, said dog mandrel means movable from said first to said fourth positions against said resilient means to permit retracting of said dog means.

Claim 5

A kickover tool comprising, stem means adapted to be run in a tubing, tool carrier means pivotally mounted on the stem means and releasably latched in a first position for running and pivotal to a second position for setting or pulling of a tool, dog mandrel means having dog means thereon and slidably mounted on the stem for movement between four positions to control operation of the kickover tool, means maintaining said dog means extended in said first and second positions and permitting retracting of said dog means in said third and fourth positions, means releasing said latch to permit pivoting of said tool carrier means upon movement to said dog mandrel means from said first to said second position and relatching said tool carrier means in said seecond position when the tool carrier means reaches said second position; said releasing means releasing said latch upon movement of said dog mandrel means from said second to said third position, means yieldably resisting movement of said dog mandrel means from said first to said second position and from said second to said third position, and resilient means biasing said dog mandrel means toward movement from said first to said second positions and from said second to said third positions, said dog mandrel means movable from said first to said fourth positions against said resilient means to permit retracting of said dog means.

Claim 6

A kickover tool comprising; stem means adapted to be run in a tubing; actuator mandrel means arranged in telescopie relationship with said stem means; tool carrier means pivotally mounted on one of and connected to the other of said stem means and actuator means to pivot said tool carrier means upon relative movement of said stem means and actuator mandrel means; resilient means urging said tool carrier toward kick-over position; lAtch means selectively latching said stem means and actuator mandrel means together in first and second selective positions in which the tool carrier means is held respectively in running position and in kick-over position; dog mandrel means having dog means thereon and telescopically arranged with said stem means and actuator mandrel means for movement between three positions for controlling the kickover tool; means maintaining the dog means extended in the first and second positions and permitting the dogs to retract in the third position; means for latching the stem means and actuator mandrel means in said first position when said dog mandrel is in said first position, rendering the latch means ineffective when the dog mandrel means is moving between first and second positions, latching the stem means and actuator mandrel means in said second position when the dog mandrel means is in said second position, and rendering the latch means ineffective when the dog mandrel means is in said third position; and means yieldably resisting movement of said dog mandrel means from said first to said second positions and from said second to said third position.

Claim 7

A kickover tool comprising; stem means adapted to be run in a tubing; actuator mandrel means arranged in telescopie relationship with said stem means; tool carrier means pivotally mounted on one of and connected to the other of said stem means and actuator means to pivot said tool carrier means upon relative movement of said stem means and actuator mandrel means; resilient means urging said tool carrier toward kick-over position; lAtch means selectively latching said stem means and actuator mandrel means together in first and second selective positions in which the tool carrier means is held respectively in running position and in kick-over position; dog mandrel means having dog means thereon and telescopically arranged with said stem means and actuator mandrel means for movement between three positions for controlling the kickover tool; means maintaining the dog means extended in the first and second positions and permitting the dogs to retract in the third position; means for latching the stem means and actuator mandrel means in said first position when said dog mandrel is in said first position, rendering the latch means ineffective when the dog mandrel means is moving between first and second positions, latching the stem means and actuator mandrel means in said second position when the dog mandrel means is in said second position, and rendering the latch means ineffective when the dog mandrel means is in said third position; and means yieldably resisting movement of said dog mandrel means from said first to said second positions and from said second to said third position.

Claim 8

The kickover tool of claim 4 wherein resilient means biases the dog mandrel means from said first toward said second and third positions, and said dog mandrel means is movable against said resilient means from said first position to a fourth position where said dog means is free to retract.
