Abstract
Abstract For use with a setting tool or a retrieval tool in installing or removing gas lift valves in side pockets of a gas lift well, a kick-over tool which incorporates a knuckle capable of rotating the tool and a sleeve which slides over the knuckle to lock the knuckle in a straight position. The sleeve locks a set of bow springs against deflection. Means are included to enable the tool to function on upward movement whereby the sleeve is moved downwardly. When it is moved downwardly, the knuckle is freed to rotate and four bow springs expand. The bow springs contact the inner wall and find the side pocket causing the lower portions of the kick-over tool to extend into the side pocket, thereby positioning the attached apparatus for installation or retrieval of the gas lift valve.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
152 words
A kick-over tool for installing or removing apparatus in side pockets in gas lift wells, comprising: an elongate body; swivel means at the top of said elongate body, lock means immobilizing said swivel means, said lock means incorporating a telescoping sleeve about said body which has one position locking said swivel means; centering springs on said body at multiple locations about the circumference thereof; said sleeve means having openings through which said springs extend, said openings altering said springs between withdrawn and extended positions, said openings and said sleeve means being arranged to releasably maintain said springs in the withdrawn or extended positions; means at the lower end of said elongate body adapted to be connected to an installation or retrieval tool; and, means for controlling operation of said lock means and said sleeve to extend said springs to the extended position and enabling said body to move at said swivel means.
Claim 2
Dependent Claim
152 words
A kick-over tool for installing or removing apparatus in side pockets in gas lift wells, comprising: an elongate body; swivel means at the top of said elongate body, lock means immobilizing said swivel means, said lock means incorporating a telescoping sleeve about said body which has one position locking said swivel means; centering springs on said body at multiple locations about the circumference thereof; said sleeve means having openings through which said springs extend, said openings altering said springs between withdrawn and extended positions, said openings and said sleeve means being arranged to releasably maintain said springs in the withdrawn or extended positions; means at the lower end of said elongate body adapted to be connected to an installation or retrieval tool; and, means for controlling operation of said lock means and said sleeve to extend said springs to the extended position and enabling said body to move at said swivel means.
Claim 3
Dependent Claim
25 words
The apparatus of claim 1 wherein said swivel means includes a captured sphere having an extending connected shaft which is connected to said elongate body.
Claim 4
Dependent Claim
73 words
The apparatus of claim 1 wherein said springs connect to a circular anchor which is slidably mounted with respect to said elongate body at the upper end and which are anchored at their respective lower ends, said sleeve incorporating a ring which moves between two positions with said sleeve, one position clamping said springs close to said elongate body and the other position permitting said springs to move away from said elongate body.
Claim 5
Dependent Claim
35 words
The apparatus of claim 1 wherein said swivel means includes a captured sphere within a cap having an axial passage, said passage having a taper opening along its length to define a range of deflection.
Claim 6
Dependent Claim
79 words
The apparatus of claim 1 wherein said controlling means includes a means extending outwardly to drag on the surrounding tubing string on upward movement; means imparting a relative downward movement to said sleeve on upward movement of said tool in the tubing string; and, means carried by said body and connected to said springs and operated by said drag means to move relative to said springs in a direction causing said springs to shorten in length and bow outwardly.
Claim 7
Dependent Claim
24 words
The apparatus of claim 5 wherein said drag means includes a set of dogs mounted on collet fingers urged outwardly toward the tubing string.
Claim 8
Dependent Claim
29 words
The apparatus of claim 6 including openings in said sleeve where said dogs extend outwardly to engage the tubing string and said dogs pull said sleeve at said openings.
Claim 9
Dependent Claim
36 words
The apparatus of claim 5 wherein said springs are leaf springs fixed to said body at their lower ends and movably fixed at their upper ends and which bow outwardly through said openings in said sleeve.
Claim 10
Dependent Claim
25 words
The apparatus of claim 8 wherein said openings terminate at a ring at the lower end of said sleeve, and said springs are constrained thereby.
