ABSTRACT:
A valve stem cleaner and positioner for threaded valve stems. The cleaner and positioner is designed for use with threaded valve stems in which the portion of the valve stem to be cleaned is inaccessible from the ends of the stem as for example, in an open yoke of a valve and also for use in valve stems where an end is accessible as above the valve hand wheel. For the inaccessible portion of the valve stem the cleaner and positioner is made in hinged half portions with semi-circular members which are adapted to be fitted around the valve stem and hinged together. The cleaner and positioner has inwardly extending wire bristles which engage the threads of the valve stem and a nut portion so that when the cleaner and positioner is opened and fitted around the valve stem by means of closure means the cleaner and positioner can be closed about the valve stem. A wrench fitted on the nut can move the device about the threaded valve stem to any position as desired. In a modification where the threaded end of the valve stem is accessible, the cleaner and positioner may be made integral and simply threaded on top of the threaded valve stem and by means of the wrench fitting on the nut portion moved to a desired position on top of the hand wheel.
