  • Patent number: 4285096
    Abstract: An indestructible handle for a mop or broom or the like comprises a tubular steel handle member with a solid steel plug mounted in the end thereof and protruding out of the end. The exterior of the steel plug is provided with a modified Acme thread that fits a standard thread on a push broom. The outer end of the steel plug includes a threaded opening such that it can fit on a threaded handle attachment stud on a mop frame. A plastic sleeve encases the handle member. The steel plug is mounted in the end of the handle member by crimping the handle member over the portion of the plug extending into the handle member at three equally spaced points around the handle. The threads on the plug extend into the handle, and crimping tools having a plurality of pointed projections thereon at each of the three crimping positions crimp the tubular member so that the tube is crimped inwardly between the threads of the plug, thus holding the plug in the end of the tubular member.
