Abstract:

A caulking gun or adhesive dispensing tool is driven by an expandable drive mechanism. The drive mechanism comprises a threaded shaft interfitting with the threaded inner surface of a receiving sleeve. The sleeve carries a pusher plate into a caulk receptacle for engaging a tube of adhesive material. The shaft is attachable to the chuck of a common drill. Rotation of the shaft linearly translates the sleeve and hence the pusher plate into the caulk receptacle. A drive housing interposed between a drill and the caulk receptacle generally houses the drive mechanism and extends the length of the adhesive dispensing tool to provide for easier manipulation thereof. The adhesive dispensing tool may include a handle and a pair of wheels for easier manipulation of the tool.

Abstract:

An ambulatory cutting device is provided. The ambulatory cutting device provides a blade mounted, by way of a blade holding assembly, to a wheeled frame. The wheeled frame has handles for a user to push the wheeled frame along a surface supporting a roofing membrane or other cuttable membrane, wherein the blade holding assembly maintains the mounted blade at an elevation just below the supporting surface so that the membrane is cut as a user pushes the wheeled frame.
