WATER CLARIFIER FOR AUTOMOBILES Filed July 29. 1937 MW 7 MW ATTORNEYS.

Patented Feb. 27, 1940 PATENT OFFICE l WATER ommms For, AuroMoB ILns Arthur Gr Busli, Davenport, Iowa Application July 2951937, Serial No; 156,364 Claims, (01. 210-165);

Myinvention relates toa new and useful improvement for water clarifiers for automobiles. The objects of my invention are to provide a small, compact, easily manufactured clarifier to be mounted in the cooling systemof a'watercooledautomobile which will not only separate 1 out a large portion of the sedimentary material heavier than water, but will also separate out the oily, foamy sludge and other lighter than water 10 materials which accumulate in the circulating system; and will provide means for drawing into the radiator the vapors arising from the water,

alcohol, etc., used in the cooling system so as to condense and save the alcohol, etc. ll I accomplish these objects by the means illustrated in the accompanying drawing, in Which- Figure l is a rear elevation of my. apparatusattached to the rear wall of the upper water chamber of a radiator, but with a part of the rear plate of the clarifler broken away to show the interior construction. a

. Figure 2 is a similarrear elevation of an alternate form of my device, withlthe rear plate broken awayto show the interior. I

2 Figure 3 is a sectional'elevation on the line 3'-3 of Figurel.

My apparatus comprises a rectangular housing l,'which comprises the top, bottom and right and left side walls of the body ofrny clarifier. The

. housing I is provided with a flange la at its front edge, which is attached by welding or other suitable means, to the rearwall 2 of the upper chamber or partof the radiator ofv the automobile, the top ofwhich appears in Figure 1 as 3;

The rear edge of the housing i is likewise pro vided with a similar flange lb, which extends all around the housing and to which the rear plate 4 is attached by bolts 5, or other suitable means,

which render it readily detachable from the 40 flange lb;

The left side plate of the housing I is formed with an annular flange Sprotruding to the left thereof as shown in Figure 1,.to which the hose 1 may be connected, the other end of the hosev l forming a part of the water line from the pump or, from the engine block, as the' case may be to the radiator; 7

The right side plate of the housing I has an elliptical opening 8 formed therein around which a waste pipe 9 is secured by welding, brazing, or

. radiator chamber as the pump draws the Wat-e1 cannot be removed by flushing. the radiator must be unsoldered and the tubes A rubber hose H may be attached to the lower end of the waste pipe 9, to conduct the sludge,

sediment and water when drained off, to any desired position below the engine and prevent soil- .ing and wetting theengine when the clarifier is 5" Upon theinner face of the rear plate 4 I attach a cylinder [3 which is provided with flanges l3 united to the wall 4 by welding, soldering or other suitable means. 1 I0 The inner end of the cylinder I3 is formed to fit snugly upon an annular'flange l5, which is pressed outwardly from the rear wall Zof the radiator. The flange l5 ispreferably formed in the shape of a short cone frustum so asto fit snugly within the opening end of the cylinder !3,

and to leave anopening I6 in the rear wall of the upper chamber of the radiator 'so that the water may pass'freely from the cylinder i3 into action of the pump in the circulating system, will normally aid in drawing such vapors into the out of the bottomof the radiator. I 3013 In the case of excess steam accumulating in the radiator, the opening I! will I also permit such steam to pass into the clarifier and out to the atmosphere through the pipe 9, thus avoiding the blowing of steam and sludge out around 35*. the radiator cap. M i v I -It is well known among automobile drivers that at times the oil from around the bearing of the pump shaft or from other sources, works into the water circulation inthe' cooling system. When 40:

' this occurs, the oil readilypicksup particles of rust from inside the engine, block; also particles of lime in the radiator, or other sediment that may be'in the water, and forms a'sort of emulsion or sludge.

' This sludge becomes thick enough to clog up the radiator tubes and smaller water passages, and greatly impairs thecooling capacity of a 1 radiator; It'is not easily soluble. Itirequently In many cases, 50.

or water passages scraped out with steel rods ;or other scraper. Until thuscleaned out, the radiator will heatlan'd often thesteam escaping from. around the radiator-cap will carryoily sludge metal apron I9 provided with a plurality of small holes or bores it, which will permit water to pass through them but are too small to permit the passage of the oily sludge.

The apron 59 may be formed with a flange l9", by which it may be united to the rear plate 4 by welding or other suitable means.

The remainder of the cylinder Ell is made of fine screen wire, fibre, cloth. or other suitable material having a line enough. mesh to prevent the passage 01 sediment, particles of lime, rust, etc., but open enough and having sumcient size and capacity to permit the flow of the water go ing from the pump to the upper radiator cham ber.

The radiator may be provided with the usual cap, 26, for filling it. The filling cap may be mounted upon the body of the clarifier if desired, or in any other desired part of the water circulating system instead of upon the radiator and will perform the same function.

An overflow pipe 22 may be mounted in the throat or neck of the radiator under the filling cap, if desired, but with my apparatus, this is not necessary as the pipe 9 will act as ail-over flow pipe.

Figure 2 shows an alternate form of my device in which the apron liia is mounted above the cylinder id, as by the flange it", it extends downwardly to the left of the cylinder 53 to about the middle lineof the cylinder. When a separate apron i911 is used, the entire cylinder is may be formed of wire, gauze or. other suitable screening, as the apron so formed will keep the sludge away from the cylinder and prevent the screen being clogged up by it.

In the operation of my apparatus, the water is forced by the pump from the engine block into the pipe i, from which it passes into thehousing I, theinner part of which might conveniently be considered as forming an upper or sludge chamber l4 and a lower or sediment chamber 22. As the Water passes through the .pipe I the oily sludge, being lighter than the As the water passes into the clarifler, the" sludge will accordingly pass upwardlyinto the sludge chamber Hi, sliding along the apron until it reaches the aperture flin'theright side walland passes down into the drain pipe 9, being separated from the water by the apron I 9 and the small openings l9which permit the water to pass through the apron, but prevent the passage of the sludge.

The sediment bearing portion of the water will pass downwardly into thesediment chamber [2, as most of the water will pass in that direction. From the sediment chamber I2 the water will pass through the screen 20, which will screen out the sediment, and into the cylinder l3, and.

The entire circuit is closed except for the aperture 8 opening into the sludge pipe 9 and the overflow pipe 22, if an overflow pipe is used.

It will thus be seen that my apparatus carries out four functions simultaneously. It strains out the sediment and collects it in a chamber from which it can be removed by opening the cook l. It carries the sludge away from and out of the circulating system so that it cannot get into the radiator and it provides means for drawing off the vaporized alcohol, water, etc., so as to prevent waste thereof. It also provides an outlet .in case the radiator is overflowed.

have shown the rear plate 4 secured to the rear flange lb of ,the housing I by small bolts 5, with a rubber gasket 5 inserted between the 'plate. 4 and the flange II), but I do not limit my claims to this particular form of fastening, for it is obvious that any suitable form of fastening may be used which will be secure against leakage, and fastenings may be utilized which will permit a much speedier removal of the plate 6 than the bolts.

The form of my apparatus, with the rear plate A removable, makes it possible to easily and readily take out the cylinder l3 and apron l9 for cleaning, as well as for the purpose of cleaning out any sediment which may accumulate in the sediment chamber I2. However, with this form of apparatus, it will seldom be necessary to remove the plate 1,, because the pipe I0 is preferably made large enough to freely drain off the sediment from the sediment chamber l2, and the aperture 8 is made large enough to readily carry ofl'the sludge which may accumu late in the sludge chamber M.

The opening or aperture I1 is preferably placed above the level of the bottom of the aperture 8.

sothat the water system; may be flushed out and the sludgecarried out through the drain pipe 9 without passing into the radiator chamber through the opening I1.

It is common practice in connection with the cooling system for internal combustion engines, to provide radiators which comprise upper and lower chambers united by a large number of small tubes or conduits of various shapes and designs. m

In the manufacture of my invention, I prefer to mount my housing approximately at the level of the upper radiator chamber so that the water passing through the screen and the vapors passing through the vapor opening, will enter directly into the upper chamber of the radiator and it is obvious that my clarifying chamber'may bemade integral with the upper radiator chamber without departing from the spirit of my invention.

It is likewise obvious that my clarifier may be inserted in the conduit which passes from the lower chamber of the radiator to the pump or to the engine block if desired, and in such cases a bend may be formed in the sludge pipe the top of. which will be at the normal upper water level of the system, but I prefer to mount it in the conduit leading from the engine block to the radiator, because in that position, it will tend to separate light particles of rust, lime, oily sludge, etc., coming from the radiator block, before it passes into the radiator and thus pre vent it from getting into the tubes or small conduits connecting the upper and lower chambers of the radiator.
