Abstract

The mechanism includes backstop 10 which is effective on rotatable pawl 11 and which is actuated by frontstop 12 for such pawl so that backstop 10 is out of the path of movement of pawl 11 under pawl-disengaging conditions to reduce wear on backstop 10. Pawl 11 is rotatable with shaft 13. Both backstop 10 and frontstop 12 are movable into the path 11 and which is actuated by frontstop 12 for such pawl so that backstop 10 is out of the path of movement of pawl 11 under pawl-disengaging conditions to reduce wear on backstop 10. Pawl 11 is rotatable with shaft 13. Both backstop 10 and frontstop 12 are movable into the path of movement of pawl 11 so that, when pawl 11 is positioned between stops 10 and 12, it is held against movement in either direction. Return spring 14 holds frontstop 12 out of pawl-engaging position.

Actuated Clutch Pawl Backstop Mechanism

The mechanism includes backstop 10 which is effective on rotatable pawl 11 and which is actuated by frontstop 12 for such pawl so that backstop 10 is out of the path of movement of pawl 11 under pawl-disengaging conditions to reduce wear on backstop 10. Pawl 11 is rotatable with shaft 13. Both backstop 10 and frontstop 12 are movable into the path 11 and which is actuated by frontstop 12 for such pawl so that backstop 10 is out of the path of movement of pawl 11 under pawl-disengaging conditions to reduce wear on backstop 10. Pawl 11 is rotatable with shaft 13. Both backstop 10 and frontstop 12 are movable into the path of movement of pawl 11 so that, when pawl 11 is positioned between stops 10 and 12, it is held against movement in either direction. Return spring 14 holds frontstop 12 out of pawl-engaging position. Magnet 15 is effective on frontstop 12 to counteract spring 14. Backstop 10 is rotatably mounted on shaft 16 and is normally held out of the path of movement of pawl 11 by torsional washer 17. Leaf spring 18 is fixed on frontstop 12 and overlies backstop 10. When magnet 15 is energized, frontstop 12 is moved into the path of movement of pawl 11. Leaf spring 18 tends to move backstop 10 into the path of movement. Pawl 11 moves stop 10 against spring 18 so as to move into abutting relationship with frontstop 12 and then backstop 10 moves back of pawl 11.
