  • Patent number: 4222142
    Abstract: A tip for a cleaning rod is disclosed. The tip has a threaded end to be received in the threaded end of a cleaning rod, and a rag receiving loop on the end opposite the threaded end. Bristles are supported on the body of the tip between the threaded end and the slotted end, and a sleeve slides over the bristles from a position adjacent the slotted end holding the ends of the bristles to the tip. The sleeve can be slid to the end remote from the tip over the roots of the bristles allowing the bristles to diverge outwardly to thereby give the user the choice of cleaning the gun with or without the wire bristles.
