Abstract:
1. A tool comprising: a tubular body having a bore formed therein and an axis; a guided sleeve disposed within the bore, the guided sleeve adapted to rotate about the axis and having an outer surface; a reciprocating sleeve disposed within the bore, the reciprocating sleeve adapted to translate axially from a first position to a second position and constrained to rotate in a first direction when translated from the first position to the second position, and having an inner surface; a seat connected to the reciprocating sleeve, the seat configured to restrict an obstruction element passing through the tool, wherein a restriction of the obstruction element causes a pressure differential across the seat causing the seat to translate axially; a gearwheel located on the outer surface of the guided sleeve, the gearwheel comprising a plurality of alternating gear teeth and gear troughs and the gear teeth are configured to move the pawl teeth radially; and at least one pawl located on the inner surface of the reciprocating sleeve, the at least one pawl adapted to push the gearwheel in response to the reciprocating sleeve rotating in the first direction causing the gearwheel to rotate the guided sleeve to a new position and the at least one pawl adapted to move radially in response to the reciprocating sleeve rotating opposite the first direction.
