Application August 31, 1939, Serial No. 292,939 4 Claims. (Cl.210-131l This invention relates to a cleaner adapted for installation in the water cooling line of an internal combustion engine, preferably between the water pump and radiator outlet thereto, being of such construction as to remove all undesired matter in the water such as excess water pump grease, rust" and other sediment.

It is particularly aimed to provide a structure which may be inexpensively made of non-corrosive parts, one having a removable cartridge, one having means whereby it may be attached in a novel and adjustable manner with minimum parts, and one which is generally improved and simplified as will appear hereinafter and become apparent from a consideration of the following description and accompanying drawing.

In said drawing- Figure 1 is a view showing the cleaner in side elevation, as applied in an automobile cooling system, the latter being shown fragmentarily;

Figure ,2 is a plan View of the parts primarily constituting the invention;

Figure 3 is a vertical sectional view taken on the line 3--3 of Figure 2, and

Figure 4 is a horizontal section taken on the line 4-4 of Figure 3.

Referring specifically to the drawing wherein like reference characters designate like or similar parts, the invention comprises a preferably cylindrical container or tank l0 having a bottom wall ll secured in watertight relation thereto. At the top, tank l0 preferably has a short inwardly extending flange i2.

Within the tank ill, located above the bottom wall II and parallel thereto is a shelf or support 13 for a removable cartridge generally designated l4. Said support or shelf I3 is soldered or otherwise secured in place at its margin as at l5 to the tank l0 and it has a central opening l6 so that water may pass through the cartridge.

Said support or shelf l3 divides the interior of the tankinto a lower or water receiving chamber l1 and an upper filtering or water outlet chamber I 8. The device is adapted to be connected in the water cooling system of an internal combustion engine as best shown in Figure 1. In that figure, l9 designates the engine, 20 the radiator, I

2| the outlet conduit from the radiator, 22 an inlet conduit to the water jacket of the engine and 23 a return conduit from such water jacket to the radiator. As a result, the device is installed between the water pump and radiator outlet to the pump. .It will be understood that the arrangement of the conduits and of the water system parts generally, in different cars or automobile will vary, and in some instances will be built special, and that the arrangement of the conduits, position of the cleaner and the like will vary accordingly. Removable connections are preferably provided between the tank or container Ill and the conduits 2| and 22. 1

Reverting to the cartridge I4, it consists of a. central perforated tubular drum 24 and an outer perforated tubular drum 25 providing a space filled with any conventional filtering material, for instance, asbestos, steel wool, mineral wool or slag, glass wool, with or without the inclusion of granular material like diatomaceous earth, limestone or the like. Such cartridge also has an upper end wall 26 having an annular downwardly extending flange 2'! provided with screws or the like 28 enabling removal of the top for removal and replacement of the filtering material. A spacer 29 is preferably soldered or otherwise fastened centrally to the top wall 26, aiding in centering the central drum 24. At the lower end, a bottom wall 30 is provided, having a marginal flange 3i soldered to the outer drum 25 and having a central flange or collar 32 soldered to the central drum 24 and extending snugly but removably into the opening 16. A gasket 33 surrounds the flange or collar 32 and engages wall 30 and shelf 1 3, to insure passage of the water through the cartridge from chamber i! into chamber I8 and outlet through the conduit 22.

Said tank or container I0 is removably. engaged by a generally U-shaped clamping frame or bracket 34, having a bridge 35, disposed above and across the top of the container l0, depending legs 36 at the sides of the container and inwardly extending feet or lugs 31 at the lower ends of the legs on which the container rests.

A cover plate 38 extends over the top of the container to close the same liquid tight and maintain the cartridge in place and a gasket 39 is interposed as shown. Such cover plate 38 is maintained in place with the requisite pressure, by the action of a screw 40 passing through bridge 35 at a fixed nut 4| thereon, the screw having a handle or extension 42 to facilitate its manipulation.

It will be noted that throughout the major portion of the length of the legs 36, they are offset at 43 from the container, to provide spaces 44, through which "an attaching band or clamp 45 passes. Like the frame or clamp 34, the band 45, is preferably made from a single strip of metal. Band 45 has terminal portions 46, through which a bolt 41 passes and is operable to bind the band around the container, at any desired angle and elevation. One of the terminals 46 is extended to form an attaching lug as at 48. The latter may be engaged with any convenient part, and for instance a. cylinder head'bolt of the engine i9, which may be passed through an opening 49 in the lug.

It will be clear that in operation, the circulating water within the cooling system of the engine cock in the bottom of the automobile radiator 20 serves as a drain for the cleaner and the complete system. Also, it will be noted that a gasket is not required at the'top of the cartridge between the cover plate.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

1. A cleaner for a water cooling comprising a container, filtering means therein, a support within the container for the filtering means providing a receiving chamber and an outlet chamber, a mounting frame containing the container, a cover over the container and filtering means. clamp means adjustably mounted on th frame and engageable with said cover plate, said frame including legs at the sides of the container, said legs having offset portions providing spaces between the same and container, an attaching bracket surrounding the container and passing through said spaces.

2. A cleaner for the water cooling system of an engine comprising a container closed at the bottom and open at the top, a shelf within the container spaced above said bottom to provide a receiving chamber beneath the same and an outlet chamber above the same, said shelf having an opening therethrough, a cartridge within the outlet chamber containing filtering material, said cartridge having an inlet member extending into said opening, a cover plate over the open. end of the container and engaging the cartridge, means securing the cover plate in position, comprising a screw, a generally U-shaped frame having a bridge through which said screw passes, legs depending from the bridge at the sides of the cont ainer having feet disposed under the container.

3. A cleaner for the water cooling system of an engine comprising a container closed at the bottom and open at the top, a shelf within the container spaced above said bottom to provide a receiving chamber beneath the same and an outlet chamber above the same, said shelf having an opening therethrough, a. cartridge within the outlet chamber containing filtering material, said cartridge having an inlet member extending 7 into said opening, a cover plate over the open end of the container and engaging the cartridge, means securing the cover plate in position, comprising a screw, a generally U-shaped frame having a bridge through which said screw passes,
