Composite ferrules for extension poles
A ferrule connection interface may have a first composite ferrule having an outwardly threaded portion opposite a pole receiving portion. The interface may have a first pole bonded via an engineered adhesive to the first composite ferrule at the pole receiving portion of the first composite ferrule. The interface may also have a second composite ferrule having an inwardly threaded portion opposite a pole receiving portion, the inwardly threaded portion tightly meshing with the outwardly threaded portion of the first composite ferrule to form a tight connection. The interface may also have a second pole bonded via the engineered adhesive to the second composite ferrule at the pole receiving portion of the second composite ferrule. Both first and second composite ferrules are characterized by a lack of any metallic and/or electrically conductive materials.
1. A method for connecting sections of an extension pole comprising:
(a) providing a first composite ferrule having an outwardly threaded portion opposite a pole receiving portion and providing a second composite ferrule having a recessed inwardly threaded portion defining an overlapping sleeve opposite a pole receiving portion wherein both first and second composite ferrules are characterized by a lack of any metallic and/or electrically conductive materials;
(b) connecting the pole receiving portion of the first composite ferrule to a first pole by inserting an end of the first pole into the pole receiving portion of the first composite ferrule;
(c) connecting the pole receiving portion of the second composite ferrule to a second pole by inserting an end of the second pole into the pole receiving portion of the second composite ferrule;
(d) tightening the outwardly threaded portion of the first composite ferrule to the inwardly threaded portion of the second composite ferrule to form a connection with the overlapping sleeve of the second composite ferrule overlapping at least a portion of the pole receiving portion of the first composite ferrule, wherein a first diametric step is defined by a diameter of an exterior of the pole receiving portion of the first composite ferrule being greater than a diameter of an exterior of the first pole, and a second diametric step is defined by a diameter of an exterior of the overlapping sleeve of the second composite ferrule being greater than the diameter of the exterior of the pole receiving portion of the first composite ferrule;
(e) connecting a third composite ferrule having an outwardly or inwardly threaded portion opposite a pole receiving portion to the second pole on an end opposite the second composite ferrule;
(f) connecting a tool to the outwardly or inwardly threaded portion of the third composite ferrule, wherein the tool is one or more of: a pruner and a rope, a double pulley pruner and a rope, a saw head, a saw blade, a hook saw blade and belting scabbard, and/or a limb and wire raiser.
2. The method of claim 1 , wherein: the pole receiving portion of the first composite ferrule is internally and externally unthreaded; and the pole receiving portion of the second composite ferrule is internally and externally unthreaded.
3. The method of claim 2 , wherein when the connection is formed, the overlapping sleeve of the second composite ferrule overlaps a portion of the pole receiving portion of the first composite ferrule and a portion of the first pole.
4. The method of claim 3 , wherein when the connection is formed, a portion of the pole receiving portion of the first composite ferrule extends longitudinally along a portion of the first pole beyond a terminal end of the overlapping sleeve of the second composite ferrule.
