1940- A. M. MIDDLETON REVERSIBLE SELF-CLEANING RADIATOR Filed Dec. 6, 1938 w INVENTOR r1 v I I I ATTORNEYS UNITED STATES PATENT OFFICE REVERSIBLE SELF-CLEANING RADIATOR Albert M. Middleton, East Lansdowne, Pa.

Application December 6, 1938, Serial No. 244,266

3 Claims.

The present invention relates to new and improved radiators and more particularly to such devices constructed in a manner to be reversed on a vehicle to change the flower water there'- through.

As is well known, foreign substance in a radiator caused by rust, scale and particles of oil fromthe motor, usually settles on top of the radiator core and very seldom penetrates into the cellular structure and, due to the continual circulation of water in one direction, such foreign substances will become permanently embedded in the core. Over a period of time this condition usually results in overheating of the radiator caused by faulty circulation of the water and oftentimes the radiator will leak as a result thereof. The herein described radiator being reversible and readily removable for reversing will greatly improve the above conditions. Reversing the position of the radiator places the clogged top of the core to the bottom and changes the flow of water which, through assistance of the water pump, forces out any obstruction that has a tendency to accumulate and settle in the core.- Also, a periodic reversing of the core will, toe. large extent, minimize the accumulation of foreign substance therein. j

It is, therefore, the primary object of the invention to provide a radiator for use with an oil or gasoline water cooled motor that is readily reversible whereby the direction of flow of water therethrough can be changed to prevent partial obstruction of the core of the radiator.

A still further object of the invention is to provide a reversible radiator including 'baffled tanks with extra hose and filler connections -which when not in use, are capped by novel means forming part of the invention.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawing which forms a part of the application.

In the draWing- Fi e 1 is a front elevational view with parts in tion of a radiator constructed in accordance with the present inventien.

Figure 2 is-a side elevational view of the radia tor with the lower part in section, and

Figure 3 is a top plan view of the radiator disclosed in Figure '1.

Referring to the drawing for a more detailed description thereof, wherein there is illustrated the preferred embodiment of the invention, the new and improved reversible type radiator is indicated generally by the reference numeral 5 and includes top and bottom sections 6 and 1 respectively of identical forms. 'I'hesections 6 and I include header tanks 8 and 9 respectively, each tank being formed with a baflie plate It) 5 more clearly illustrated in Figure 2 of the drawing, said tanks communicating with the cellular structure of the radiator core H in the conventional and well known manner.

The top section 6 further includes a filler 10 connection l2 extendingtherefrom and closed by a suitable cap 13, said cap being attached to the section by means-0f a chain or the like H. The bottom section 1 is likewise formed with a filler connection l5 and cap l6 attached to the section 15 by means of the chain or the like ll.

Each filler connection l2 and 15, respectively, has attached thereto by any desired means, overflow pipes l8 and I9, respectively, each pipe carryinga pet cock valve 20 and 2| respectively, one 20 of which is adapted to'be shut off when not in operation. In other words, when the radiator is in the position illustrated in Figure l of the drawing, the overflow pipe I!) is not in operation and consequently the pet cock 2| remains closed, 25 with the pet cook 20 and its associated pipe in operation and therefore open.

Inlet and outlet connections are formed on each of the sectionst and 1 one of which is adapted to be closed by an expansible plug when 30 not in use. In Figure 1 of the drawing, the top section 6 is illustrated with an inlet connection 22 supporting thereon a rubber hose 23, and an outlet connection 24 closed by the expansible plug 25. The position-of the inlet and outlet 35 connections on the bottom. section I is substantially reversed to that used in the top section 6. 0n the bottom section I the outlet connection 26 supports the rubber hose 28 and the inlet connection 21 is closed by the expansible plug 28. 40 Referring to Figure 2 of the drawing, there is more clearly illustrated the type of expansible plug used for closing the connections not in use, said plug comprising an expansible cylindrical shaped member 29 formed of rubber or similar 45 material and having extending therethrough a threaded bolt 30. A metallic washer II is carried by the bolt and is held in associated relation with the member 29 by means of the wing nut 22.

38 on the other end of the radiator. The brackets are formed with openings for receiving "the connecting members 31 for bolting the radiator to the frame 38 of the vehicle.

When desiring to reverse the position of the radiator from that illustrated in the drawing the bolts 31 and

hose connections

23 and 28 are removed. The reverse end of the radiator is then attached by means of the bolts and

brackets

33 and 34 and hose connections substituted for the expansible plugs 25 and 28'. The expansible plugs are then positioned in the

connections

22 and 26. Thus connection 21 will become the inlet and connection 24 the outlet for the radiator in its reversed position so that the flow of water through the radiator will be reversed. Naturally, when reversing the radiator the rust and scale that was formerly on the top of the core will be on the bottom thereof so that the reversing oi the flow of waterthrough the radiator will force the rust and scale from the core and it being of a metallic substance that is heavier than water will sink to the bottom of the tank and lodge in the filler neck I 5. In other words, a trap will be formed in the bottom-most portion of the radiator below the outlet connection and the dislodged rust and scale can be periodically removed from the filler neck. I t

It is to be noted that the filler caps are formed with a washer 39 best shown in Figures 1 and 2 of the drawing whereby a leakproof connection is provided to prevent loss of water through the bottom section.

Also it will be understood, of course, by those skilled in the art that variations in the hereinabove described device involving the substitution of the invention nor exceed the scope thereof as expressed in the appended claims.

What is claimed as new is: 1. An automobile radiator comprising, a casing having top and bottom header tanks, a core sup- DOrted between said tanks and in communication therewith, means for removably attaching said radiator to an automobile for reversing the position thereof, and a plurality of connections associated with said tanks adapted to permit circulation of water through said core.

2. An automobile radiator comprising, a casing having spaced top and bottom header tanks, 9. core supported between said tanks and in communication therewith, a filler connection extending from substantially the central portion of each tank, a plurality of connections extending from the rear walls of said tanks adapted to permit circulation of water from a motor through said core, and means for removably' attaching said radiator to said automobile for reversing the position thereof.

3. An automobile radiator comprising, a casing having top and bottom sections, each section formed with a header tank therein, a core supported between said sections and in communication with said tanks, filler connections extending substantially centrally of said sections, outlet members extending from the rear walls of said sections adapted to receive a hose forconnection with a motor to permit circulation of water from said motor through said core, and means for removably attaching said radiator to the automobile for reversing the position thereof.
