As clearly shown by Figure 4 of the draw ings, the body portion is so constructed that the greatest area is below the screen in. When the device has been positioned in a pipe 10 line, the‘ valve 25 is closed, whereupon the ?ow ' of ?uid is through the lower section of the body portion, upwardly through the screen, from Where the ?uid passes into the pipe line through 15 the pipe 24. Should it be desired to remove scale and foreign matter from the screen the valve 22 is opened slightly, and the valve 21 is opened to allow the flow of ?uid directly through the lower com tially the ‘entire ‘length ‘of the plate, scraping blades secured to the bar and disposed trans versely thereof in spaced relation with each other, the ends of the scraping blades being disposed in the guideways, said blades closely engaging the lower surface of the perforated plate, and means for moving the scraping blades longitudinally of the plate, removing material from the plate. 2.
