ABSTRACT:
A doughnut or puck-shaped spacer has a centrally positioned square hole. A pie-shaped cutaway portion of the spacer allows the spacer to be elastically deformed mounting on a square rod. The rod and spacers join together the bars of a bar screen rack. Bars making up a screen bed are approximately one-quarter inch thick and cantilevered sections of the screening bars benefit from being joined together to control the spacing of the bars and to add rigidity to each rack of bars which makes up the bar screen rack. For ease of assembly, canted slots receive a square rod. The spacers are readily positioned between legs on the square rod. The individual bars are then joined by tightening a nut at the threaded end of the rod, clamping the bars in spaced parallel relation.
