ABSTRACT:
An articulated handle comprises a firm arm pivotally mounted on a stationary support and a second arm pivotally mounted on the first arm to pivot perpendicular relative to pivotal movements of the first arm. A lever is also pivotally mounted on the support and a connecting rod is pivotally interconnected between the lever and the second arm. The valve stems of adjacent control valves are operatively connected to the first arm and to the lever, respectively, whereby movement of the handle in one direction will actuate one valve and movement of the handle in a second, perpendicular direction will reciprocate the other valve.
