ABSTRACT:
A material collector for a fluid container having a bottom drain outlet, such as a swimming pool. The collector includes an open top receptacle provided with a perforate side wall or bottom wall. An imperforate skirt extends outwardly and downwardly from the upper margin of the side wall and has an outer periphery spaced from the side wall for engaging the bottom of the fluid container when the receptacle is spaced above the drain outlet. A dome-shaped cover above the receptacle forms a duct with the skirt to permit material, such as debris, to be swept by the flow of the fluid of the container into the open top of the receptacle where the receptacle collects the material as the fluid continues to flow through the perforate wall of the receptacle and into the drain outlet of the container therebelow. A post or line releasably coupled to the receptacle permits the receptacle and the cover to be lifted together out of the fluid in the container and emptied. The post or line is shiftably mounted in a hole in the cover so that the receptacle and the skirt move into engagement with the cover to close the receptacle as the receptacle is lifted a short distance by the post or line. Then the post or line, with the receptacle covered, is lifted until the receptacle and cover are out of the fluid in the container, whereupon the post or line can be releasably separated from the receptacle to facilitate emptying of the receptacle. During use, a differential pressure exists across the perforate wall of the receptacle because of fluid flow through the porous wall to cause the outer periphery of the skirt to be in sealing engagement with the bottom of the container.
