Ferrules for pole and tool extension

Abstract

A ferrule system includes: a first ferrule comprising a proximal end for engaging a first implement and a threaded portion opposite the proximal end; and a second ferrule comprising a distal portion for engaging a second implement, a proximal portion opposite the distal portion and comprising teeth, a threaded portion intermediate the distal portion and proximal portion and configured to engage the threaded portion of the first ferrule. Teeth are mounted on the first ferrule and are biased to automatically engage the teeth of the proximal portion of the second ferrule as the threaded portion of the first ferrule engages the threaded portion of the second ferrule such that only tightening rotation of the second ferrule relative to the first ferrule is permitted when the teeth mounted on the first ferrule are automatically engaged with the teeth of the proximal portion of the second ferrule.
