Chemical feeder

Abstract

Abstract THIS INVENTION RELATES TO A CHEMICAL FEEDER SUITABLE FOR USE WITH BODIES OF WATER SUCH AS SWIMMING POOLS. ITS PURPOSE IS TO HOLD AND ADJUSTABLY REGULATE THE QUANTITY OF A SLOWLY SOLUBLE MATERIAL WHICH IS DISSOLVED INTO A BODY OF WATER PER UNIT OF TIME. THE FEEDER INCLUDES A FLOAT MEMBER WHICH FLOATS ATOP THE WATER AND WHICH HAS ENGAGED TO IT A CONTAINER MEMBER HAVING A CAVITY THEREIN WHICH CONTAINS THE SAID MATERIAL. THE SAID MATERIAL WILL FREQUENTLY BE A CHLORINE-RELEASE MATERIAL IN THE FORM OF RELATIVELY SMALL PELLETS. THE CONTAINER MEMBER HAS A BOTTOM WALL AND A SIDE WALL, AND ITS ELEVATION RELATIVE TO THE FLOAT, AND THEREBY RELATIVE TO THE SURFACE OF THE WATER,IS VERTICALLY ADJUSTABLE. A PORT ENTERS THE CAVITY THROUGH ONE OF THE WALLS AT A LEVEL BELOW THE SURFACE OF THE WATER SO THAT THE WATER WILL RISE IN THE CAVITY TO THE SAME LEVEL AS THAT OF THE SURFACE. THE AMOUNT OF SURFACE AREA OF THE MATERIAL WHICH IS EXPOSED TO SOLUTION BY THE WATER IS ADJUSTABLE AT LEAST IN PART BY RAISING AND LOWERING THE CONTAINER MEMBER, BECAUSE THE WATER LEVEL WILL THEREBY BE HIGHER OR LOWER IN THE STACK OF MATERIAL IN THE CONTAINER MEMBER. THE SIZE OF THE CONTAINER MEMBER PERMITS A SUBSTANTIAL RESERVE SUPPLY OF THE MATERIAL ABOVE THE WATER LEVEL SO THAT AS THE MATERIAL IS DISSOLVED BELOW THE WATER LEVEL, ADDITIONAL MATERIAL FALLS BY GRAVITY TO A LEVEL BELO THE WATER SURFACE SO AS TO MAINTAIN SENSIBLY CONSTANT THE AVAILABLE SURFACE AREA OF MATERIAL AVAILABLE TO BE DISSOLVED.
