Patent ID: 8230951

Claim:
An expandable apparatus for use in a subterranean borehole, comprising: a tubular body having at least one opening extending between a longitudinal bore of the tubular body and an outer surface of the tubular body; at least one member positioned within the at least one opening of the tubular body, the at least one member configured to move between a retracted position and an extended position; a push sleeve disposed within the longitudinal bore of the tubular body and coupled to the at least one member, the push sleeve configured to move the at least one member from the retracted position to the extended position responsive to a flow rate of drilling fluid passing through the longitudinal bore; a traveling sleeve positioned within the longitudinal bore of the tubular body and partially within the push sleeve, the traveling sleeve configured to secure the push sleeve from axial movement within the tubular body in an initial position; an uplock sleeve coupled to the tubular body, the uplock sleeve configured to secure the traveling sleeve from axial movement within the tubular body in the initial position, wherein a proximal end of the uplock sleeve is positioned adjacent to a proximal end of the traveling sleeve in the initial position; and a lower sub coupled to the tubular body, the lower sub having a longitudinal bore sized and configured to enable the traveling sleeve to translate through the longitudinal bore of the tubular body and into the longitudinal bore of the lower sub and wherein a portion of the traveling sleeve is configured to travel into the lower sub.
