ABSTRACT:
The pick-up nozzle has a large flat inlet face with a gradually tapering housing extending upwardly therefrom to an angularly disposed inclined suction hose attachment. A filter screen is disposed across the inlet face with its periphery seated against a shoulder in the housing. Peripherally spaced feet extend downwardly from the housing periphery to support the screen above any surface upon which the nozzle may rest. A closure disc is spaced beneath the screen with its periphery engaging shoulders in the feet to protect the screen and restrict entrance of liquid thereto to the spaces between the several feet. A single vertical bolt suspends the screen and closure disc from the top of the housing with spacer sleeves thereon to secure the screen and disc in proper spaced position. The closure disc is dished upwardly to leave a space for the head of the bolt above the plane of the bottom of the feet. A float is pivotally attached to the top of the nozzle to maintain the latter at a preferred level in the water.
