ABSTRACT:
A device for positioning a rotary member at a desired angle relative to a fixed member includes a first shaft sleeve mounted in the rotary member, and a second shaft sleeve mounted in the fixed member adjacent to and axially aligned with the first shaft sleeve. The first and second shaft sleeves have a plurality of inward and axially extending clutch teeth notches. A shaft member has a first section slidably mounted in and extending through the first shaft sleeve, a second section slidably disposed in the second shaft sleeve, and a central section connecting the first and second sections and having a plurality of axially extending and outwardly projecting clutch teeth protrusions. The shaft member is slidable between the first and second shaft sleeves to interengage or disengage the first and second shaft sleeves. The central section is moved towards the first shaft sleeve to disengage the central section from the second shaft sleeve, and towards the second shaft sleeve to engage the central section and the second shaft sleeve.
