Abstract: A method and apparatus for tensioning multi-strand endless chain conveyors ensuring equal displacement and constant alignment of each strand of endless chain. Included are a hydraulically actuated cylinder assembly, a equalizing yoke assembly, and a guide frame assembly. Hydraulic lines supplying fluid to the cylinder assembly have both check valves to prevent retraction and pressure sight indicators to signal when proper hydraulic pressure is achieved during adjustment. A common yoke and guide track is included to maintain equal displacement of chain strands while applying tensioning force. Also included is a guidance apparatus that prevents seizing of components due to foreign debris and also allows for easy removal of system for maintenance or replacement.

Abstract: An animal feed mixer includes an auger of unique design. Inserts having cutting edges are positioned at spaced locations in notches provided therefor in the peripheral edge of the auger flight. The inserts co-act with the sides of the mixer to cut and chop fibrous material so that is can be better intermixed with other feed components.
