A universally mounted lever 60 secured to a lever 20 actuates two output elements 10, 11, e.g. connected to hydraulic valves, via a linkage in which each pivot joint comprises a pivot bolt in threaded engagement with both the connected members, with axial clearance between said members, so that each member is adjustable and positively located relative to the member(s) to which it is pivoted, in a direction axial of the pivot bolt. The lever 20 is pivoted by a bolt 41 to a lever 14 mounted in a fixed yoke 45 by a pivot bolt 53 normal to the bolt 41. Lever 14 is pivoted by a bolt 18 to the element 10, and lever 20 is pivoted by a bolt 26 to a block 70 which is pivoted to the element 11 by a bolt 76 normal to the bolt 26. The elements 10, 11 can be actuated independently or conjointly.</p> |
