US 11,536,528 B2 · Extraction pole assembly for extracting projectiles from a bore

Abstract

An extraction system for removing an object from a bore, the extraction system comprising an extraction pole assembly comprising a plurality of extraction poles, each extraction pole having a proximal end and a distal end; and a plurality of centering couplers, each centering coupler of the plurality of centering couplers comprising a partial spherical outer surface sized to complement a diameter of the bore, a proximal end configured to couple to a distal end of an extraction pole, and a distal end configured to couple to a proximal end of the extraction pole. The extraction pole assembly can be operable with a press assembly comprising a clamp configured to secure to the structure having the bore, and an extendable member configured to provide an input force to an extraction pole of the extraction pole assembly.
