Abstract
Rotary handle device includes a coupling mechanism between the handle and a driven member. The handle is rotated about an axis and can also be axially moved between first and second positions. When the handle is in the first axial position it is operatively engaged with the driven member, and when the handle is in its second axial position it is operatively disengaged from the driven member. The handle drives the driven member via a coupling mechanism in the form of a keyed coupling between the handle and the driven member. The handle can be locked or receive a lock out device against rotation when it is in its second axial position. The keyed coupling and/or the pin and track arrangement can be used to permit axial movement of the handle only when the handle is in a predetermined orientation. The handle mechanism is shown in combination with a rotary operated valve having a valve stem as the driven member.
