Abstract
In a mixer having an elongated rotatable drum surrounded by coaxial front and rear tires, the invention facilitates adjustment of the positions of the two trunnion units that supportingly and drivingly engage each tire. Each trunnion unit comprises a base member horizontally shiftably slidable on the mixer frame and a tire engaging roller confined to rotation relative to the base member. Opening to front and rear ends of each trunnion unit are holes that are coaxial with its roller axis. Fixed to one side of the mixer frame are two locating fixtures, each having holes opening to front and rear end surfaces thereon, all of those holes having coinciding axes. Three U-shaped gages are provided, each having tangs which are closely receivable in said holes and which project laterally from opposite ends of an elongated lengthwise adjustable body portion. Two of the gages are used with the locating fixtures to position their adjacent trunnion units. The third gage, substantially longer, is used to position the other two trunnion units.
