Description

Patented Nov. 7, 1950 UNITED STATES PATENT OFFICE WATER PURIFYIN G AND CONDITIONING APPARATUS 4 Claims.
1 This invention relates to water purifying and conditioning apparatus particularly adapted for engines which employ a water circulating system purify, i. e.filter the water and remove therefrom dirt, scales, and other solid or semi-solid impurities which remain trapped in the apparatus to be removed therefrom periodically, and which also containsconditioning means to soften the water to become after such treatment a rust preventing agent producing a rust free, scale free, dirt and grease free cooling system.
A further object is to provide an apparatus which is so constructed that, its cartridge can readily be replaced, and in which the cartridge is designed to efficiently purify and soften the water. l i
A still further object to provide an apparatus which is most economical to manufacture and which because of its efiiciency, results in savings in radiator repairs and servicing expense.
Still further objects will become apparent in the following specification and in the accompanying drawing in which a longitudinal sectional view, partly in elevation, is illustrated of an apparatus embodying a preferred form of the invention.
In this drawing, 10 is a substantially cylindrical shaped housing having an inlet II at one side, and a closed bottom [2 forming a sump l3. M is a cup shaped top, adapted to contact the top edge l5 of housing HI. [6 is an annula washer, between edge l5 and top l4.
ll are identical bushings inserted in the center of the top I l and the bottom of housing 10, respectively. Each of these bushings has a pretenably polygonal flange [8, a cylindrical portion l8 adjacent the flange, and a threaded terminal 2%. Each bushing is threaded interiorly at 2| and bored out at 22 to communicate with cross ducts 23 through the walls of the bushing.
24 is a central tubular element, its ends engaging the terminals 20 of bushings I1. 25 is a washer interposed, between the flange l8 and the top I 4. The bottom bushing is, preferably, welded to the bottom [2 of housing I0. It is obvious that by screwing the terminals 20 of each bushing into element 24 by a wrenchengaging the polygonal 2 flange I8 of each bushing I1, the top l4 and the housing H) are drawn together and against washer l6, making tight joints between them;-
26 is a cartridge which comprises, preferably, a cylindrical metal shell 2! and a cover plate 28 at its top and bottom, respectively. Cover plates 28 are each turned over the shell 2! at29 and centrally at 33 to clear the tubular element 24. Each plate 28 is provided with perforations 3|.
32 is a closely woven disc of cloth or the like, placed between the to of shell 2'! and. the top cover plate 28. 33 is a discof wire screen having a central hole disposed between the plate 28 and the cloth disc 32. In pressing the plate 28 upon the top of the shell 21, the outer edges of the cloth disc 32 are confined between the plate and the shell as clearl shown in the'drawing.
34 is a center tube made of metal or other suitable material which surrounds the tubular element 24 and forms the inner wall of the cartridge 26. V l J i At the bottom, the cartridge has a disc 35 of wire screen similar to disc 33. Above the disc 35 is'another closely woven disc 36 of cloth or the like; also similar to disc 32 at the top, but held in place by a snap ring 31 at its outer edge. The inner edges of both cloth discs 32 and 36 are clamped between turned over portions 330i plates 28 and center tube 34 while thecartridge is assembled.
Within the cartridge, in its lower portion, is a quantity of absorption and filtering material such as sawdust, coke, cellulose pulp, charcoal or other porous material, designated as 38 in the drawing. On top of this material is placed an annular disc 39 of closely woven cloth or the like- Over this disc 39 is placed a quantity of ion exchangematerial for softening water, such as zeolite, porous stone, sand, or other porous minerals, sufilcient to fill the cartridge. This material is designated in the drawing as 40. i i
4| is a washer placed over a shoulder adjacent the terminal 20 of bottom bushing. ll; 42 is a helical spring between washer H and another washer 43 at the bottom of bottom plate 28. This spring serves to keep the top of the cartridge tightly against the washer I6.
44 is a drain plug screwed into the bottom of bushing I! at the bottom of the housing.
In applying the device to an engine of the automotive type, it is connected directly into the water pipe of the circulating water system for full flow filtration, or in a by-pass position, as desired. The water enters at the inlet II, is forced to the bottom, and then upwardly through the perforations in bottom plate 28, wire screen 35, cloth disc 33, first through the absorption material 38, thence by way of disc 39 through the water softening material 40, cloth disc 32, wire screen 33, and the perforations 3! of the top plate 28 into the space above the cartridge 26, thence by way of ducts 23 into the outlet of the device to be passed into the system.
Any solid or semi-solid impurities will be ill-- tered out-of the water at the lower portion of the cartridge and accumulate in its sump. Removing the drain plug 44 periodically permits these impurities to be flushed out without removing the cartridge. Filtered water only passes the material 40 so that it can be full effective for conditioning purposes.
The device can be readily taken apart and the cartridge removed b merely unscrewing one of of the bushings H. The bushings ll, being identical in shape enable the device most economically to be manufacturedandserviced.
The combination water filtering and conditioning means results in a simple and effective device which removes rust, scales, dirt, grease, etc. from the inner passages of the cooling system including the radiator, cylinder head and block, hot
water heater, etc,
It is obvious that many changes of form, proportions and minor details of construction may be resorted to without departing from the principles or sacrificing any of the advantages of the invention as defined in the appended claims.
What I claim as new, is;
1. In an apparatus for purifying and conditioning water in cooling systems for engines of the automotive type comprising a housing having a water inlet and a water utlet, a removable cartridge interposed between the inlet and outlet and containing a filtering agent for purifying the Water and a conditioning agent for the water, the housing having an upper part and a lower part containing a sump, the water inlet being adjacent the top of the lower part above the sump, a bushing in the upper part and a bushing in the lower part, a connecting element between the bushings, means in the bushings engaging the element to draw the upper part and the lower part together, the cartridge being of annular shape having imperforate side walls and having screened inlet openings at its bottom and screened outlet openings at its top, its outer diameter in spaced relation to the wall of the lower part of the housing, and its inner diameter surrounding the element, the cartridge being disposed within thelower part of the'housi ng and the space between its outer side wall and the wall of the housing forming an annular passage for the water from the inlet to the sump, and means in the sump to force the cartridge toward a shoulder in' the upper part of the housing, the bushings being identical, the one in the upper part containing the water outlet, and the one in the lower part containing a plug for periodical removal for cleaning the sump.

3. In an apparatus as defined in claim 2, the bushings in the upper and lower parts of the housing being identical, each comprising an interiorly threaded portion, cross ducts in communication with the threaded portions, and threaded terminals adapted to engage the connecting element.
4. In an apparatus as defined in claim 2, the means to force the cartridge toward the upper part of the housing comprising a helical spring, and washers at both ends of the spring contacting, respectively, the bottom of the cartridge and the bushing in the lower part of the housing, so that water will be admitted into the cartridge at its bottom only and travel lengthwisely through the cartridge to be discharged at its top.
