Abstract

The embodiments of the invention as described herein relate to a tool or device for sealing exterior duct joints. The device is designed and configured to drive a semi-solid mastic or cement-like material through a hose and a custom designed applicator wand. The various embodiments of the invention include cordless, lightweight and portable versions. This tool is designed to assist in the sealing of ductwork. An extension on the end of the wand enables a user to reach several areas that are either difficult to access, or awkward to seal using traditional techniques. Various embodiments of the spreader head have been designed to perform better for different parts of the duct system. The user only needs a ladder to seal the top of the supply trunk duct, the remainder of the ductwork can be sealed standing on the floor.

Dependent claims

A device for sealing joints on ducting, said device comprising:

a cylindrical dispensing system having a first end for dispensing sealant;
a flexible applicator tube operatively attached at one end to said first end of said cylindrical dispensing system;
a rigid applicator pipe attached at a controller end to an other end of said applicator tube;
a spreader head attached to a dispensing end of said rigid applicator pipe;
an actuator operatively connected to a second end of said dispensing system;
a plunger having a circular cross section, attached to said actuator, said plunger sized and configured to fit within said cylindrical dispensing system;
a control handle and trigger assembly connected to said controller end of said rigid applicator pipe;
and
a circuit comprising a battery operatively associated with a motor, configured to drive said actuator along said cylindrical dispensing system,
wherein, when said trigger is activated, said battery drives said actuator to travel along said cylindrical dispensing system, propelling said sealant out through said first end of said cylindrical dispensing system, along the flexible applicator tube, and said rigid applicator pipe and out through said spreader head.
