Abstract
Hydraulic displacement mechanisms, and methods of using hydraulic displacement mechanisms to remove cables jammed or stuck in a conduit or other passageways, are disclosed.
Claims20
A method of utilizing a hydraulic displacement mechanism to dislodge a stuck cable, the method comprising:
- inserting the stuck cable through the hydraulic displacement mechanism;
- attaching a clamping mechanism to the stuck cable, wherein the clamping mechanism is located proximate to the hydraulic displacement mechanism;
- and
- actuating the hydraulic displacement mechanism by injecting hydraulic fluid into the hydraulic displacement mechanism to apply force to a piston and cause the piston to move a rod along an axis such that the hydraulic displacement mechanism engages the clamping mechanism to free the stuck cable.

A method of utilizing a hydraulic displacement mechanism to dislodge a stuck cable, the method comprising:
- inserting a stuck cable through a cylindrical passage in a hydraulic cylinder with the hydraulic cylinder in a retracted position;
- attaching a clamping mechanism to the stuck cable at a position proximate to a front end of a tubular body and a second end of a rod;
- injecting hydraulic fluid through a fluid port into a cylindrical chamber of the tubular body thereby forcing a piston to slidably move in a linear direction along an axis towards the front end of the tubular body, causing the rod to move in a direction such that the rod extends from the front end of the tubular body and engages the clamping mechanism;
- and
- applying a pulling pressure to dislodge the stuck cable.

A method of utilizing a hydraulic displacement mechanism to dislodge a stuck cable, the method comprising:
- extending a stuck cable through a base opening, a cap opening, and a housing channel while a hydraulic displacement mechanism is in a retracted position;
- receiving the stuck cable by a clamping mechanism in a bore of a collet wherein the collet is positioned within a housing;
- and
- actuating a hydraulic displacement mechanism by injecting hydraulic fluid through a fluid port into a cylindrical chamber of a tubular body, forcing each piston of a piston assembly to slidably move in a linear direction along an axis towards a front end of a tubular body, causing a rod to move in a direction such that the rod extends from the front end of the tubular body so as to dislodge the stuck cable in the direction.
