Help with mechanism

  1. Aug 14, 2015 #1
    Hi all,

    I was wondering if anyone had any ideas on something I'm struggling with at the moment. In the attached picture I have a sliding plate that needs to travel as shown. I have a motor mounted in the position on the picture and due to limited space its the only position available. I had intended to use a bell crank mechanism but was wondering if there was anything better? I also would like to include some loss motion somewhere in the mechanism. Any ideas?

    The motor will need the arm to remain relatively parallel to avoid jamming. The connecting rods can all change in length if necessary and the boss position could change but id rather it didn't.

    Thankshttp://[URL=http://s226.photobucket.com/user/RichRoberts44/media/9_00596_24_zpsjjn45ocm.jpg.html][ATTACH=full]199843[/ATTACH] [ATTACH=full]199844[/ATTACH]

    How about how a piston works?

    Possibly a cross plate that is driven across the slide plate by the motor.
