The two assemblies that look like short stairs are "diverters" or "kites" that would use the flow of water to pull the sweeping cables down to a desired set depth and out from directly behind the sweeper so that the sweeping cable could catch and cut a wider swath of mines per pass National Archives photo 80-G-6591
