Abstract
A nut assembly for quick adjustment of axial position relative to a threaded shaft. The nut is formed in two, physically separate sections, each having a surface portion with threads for mating engagement with the shaft. Each nut section is pivotally mounted to a bushing which surrounds the threaded shaft for movement of the nut threads into and out of engagement with the shaft threads. The sections are moved about their pivotal mountings by movement of a second bushing axially with respect to the first bushing through cooperative conical surfaces on the second bushing and on each of the nut sections. In one embodiment the second bushing is physically separate from and is moved linearly with respect to the first bushing, and in a second embodiment the first and second bushings are threadedly connected to one another with relative rotation of the two producing the relative axial movement. The nut assembly is disclosed in combination with an adjustable length pole having three, telescopingly connected, hollow rods. The threaded shaft is fixedly connected to the top rod, the first bushing to the intermediate rod and the second bushing to the lower rod.
