Abstract:

A screen frame assembly is provided for use with a screening machine. The screen frame assembly includes first and second generally planar screen frames and a coupling between the first and second screen frames that includes a tab in the first screen frame and a receiving slot in the second screen frame. The receiving slot is configured to receive the tab and includes a centering feature for laterally aligning the first and second screen frames relative to one another. The centering feature may include a pair of opposed inwardly angled edges of the receiving slot. The coupling may include an overlap region between the first and second screen frames that is engageable to thereby permit lifting of the second screen frame by a lifting force exerted upon the first screen frame.
