• an operating lever swingably mounted adjacent said disc, and having one end swingable towards and away therefrom;
• connecting means connecting between said one end of said operating lever and a point on said disc spaced from its centre of rotation, whereby swinging of said lever in one direction will be transmitted to said disc as a rotary movement thereof in one direction, and swinging movement of said lever in the other direction will cause rotation of said disc in the other direction;
