Forsyth, Los Angeles, Calif. Application December 7, 1943, Serial No. 513,272 3 Claims. (01. 210--24) 1 2 ful improvements in water softeners, particularly chamber IS. The chamber I5 is for the reception of zeolite between upper and lower layers of ?ne for use ,in conjunction with various types of domestic water heaters, and has for its primary object to provide a device of this‘ character com prising a novel construction, combination and the lower, portion of the chamber I5 preferably The present invention relates to new and use gravel or course sand. The perforations in the plates I I are small enough to prevent the passage of such ?ne gravel or course sand. The sand in is approximately to the level of the dotted line H. The upper layer of gravel or sand may be of substantially the same thickness. Other objects of the invention are to provide A hard Water inlet I8, comprising a control a water softener of the aforementioned character 10 valve I9, connects the supply line ‘I to the cham which will be comparatively simple in construc ber I4 through the bottom 4 of the tank I.

The softened water lectively supply water to the top or bottom of leaves the compartment 35 through the outlet 59. said tank including a valve-controlled stand pipe To. regenerate the softening agent in the chamber 35 of the tank 28, the valve 52 is closed and the closure 58 is removed to permit the chamber 32 to fill with water to the desired level from the chamber 36 through the pipe 31. When the water in the chamber rises to the desired level, the valve is closed. Salt is then placed in the chamber 32 for forming a brine solution. The valve M is opened for drawing the brine from the chamber 32 into the compartment 36 through the pipe 31', said brine ?owing downwardly through the zeolite in the chamber 3! and being drained off through the pipes (it and 45. The closure 439 is then replaced. The valve $3 is then opened for the passage of Water under pressure through the pipe 39 into the chamber 32. This water flows downwardly in the chamber 32 and upwardly in the pipe 37 into the compartment 36. The water then ?ows downwardly in the chamber 3i and discharges through the pipes 44 and 46, thus thoroughly ?ushing the apparatus. extending upwardly into the tank through the -. bottom thereof to a point adjacent the top of the same, vertically spaced ?anges mounted in the tank, vertically spaced perforated plates for the reception therebetween of a water softening agent removably mounted within said tank in :, ?xed positions, said plates including separate perforated segments resting upon said ?anges, said segments being of such size as to be indi vidualy removable through said top opening, sec tional metallic rings removably resting on the '- marginal portions of the plate for retaining said plates in position on the ?anges by gravity, the sections of said rings being separate and remov able through said top opening, and a valve controlled outlet pipe connected to the top of said tank.
