United States Patent 3,232,283 COOLER FOR CRANKCASE OIL PAN OIL Laurell J. Toland, Ed. Taylor, Sisseton, S. Dak. Filed May 15, 1964, Ser. No. 367,668 3 Claims. (Cl. 123-4133) This invention relates to a novel cooler for the oil in the crankcase oil pans of liquid-cooled internal combustion engines, utilizing the coolants of such engines.
The primary object of the invention is the provision of a more effective and efiicient, and more adaptable device of the kind indicated, which circulates engine coolant through a cooling coil in an oil pan, from the cooler lower part of the engine cooling radiator, to the existent water pump of the engine.
Another object of the invention is the provision of a simple, relatively inexpensive device of the character indicated above, which is designed to be installed without major or difficult changes in the structure of the oil pan, the radiator, or the water pump.
Other important objects and advantageous features of the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration only, a specific form of the invention is set forth in detail.
In the drawings:
FIGURE 1 is a left-hand side elevation of an automotive internal combustion engine incorporating a device of the present invention;
FIGURE 2 is a horizontal section taken on the line 2-2 of FIGURE 1;
FIGURE 3 is a vertical transverse section taken on the line 3-3 of FIGURE 1;
FIGURE 4 is an enlarged fragmentary horizontal section taken on the line 4-4 of FIGURE 3; and,
FIGURE 5 is a further enlarged fragmentary section taken on the line 5-5 of FIGURE 4.
Referring in detail to the drawings, the numeral generally designates an internal combustion engine, having a block 12 containing a cooling jacket and having a rotary water pump 14 on its forward end, located behind an upstanding radiator 16. An oil pan 18 is located beneath the block 12, and has side walls 20 and intermediate its ends, a bottom wall portion 22, which is depressed below the remainder of the oil pan 18.
The illustrated cooling device comprises a circular cooling coil 24 which is disposed horizontally within the oil pan 18, ciose to the bottom wall portion 22. The cooling coil 24 is of a diameter to reach close to the oil pan side walls 20, and consists of at least one convolution. More than one convolution would be called for by circumstances and by the size of the oil pan and engine.
The cooling coil 24 comprises at least one convolution 26, which terminates in aligned horizontal first and second or right-hand and left- hand arms 28 and 30, respectively, which extend through the related side walls 20 of the oil pan, at locations preferably behind the coil. The arms 28 and 30 serve to increase the cooling capacity of the coil.
The arms 28 and 30, as shown in FIGURES 4 and 5, extend out through tubular gaskets 32, compressed in externally threaded tubes 34 which extend through holes 36 in the coil pan side walls 20. Inside and outside packing nuts 38 and 40 are threaded on the tubes 34, against ice inside and outside annular compressible seals 42 and 44,
which are compressed against the inside and outside surfaces, respectively, of the side walls 20, and seal the holes 36.
A hose 46 is connected to the left-hand cooling coil arm 28 and leads forwardly and is connected to one side of a regulator valve 48, having a rotary control handle 50, for regulating fiow of engine coolant to the cooling coil. The other side of the valve 48 is connected by a horizontal pipe 52 to the bottom tank 54 of the engine radiator 16.
The left-hand cooling coil arm 30 is connected by a hose 56 to a neck 58 formed on the intake pipe 60 of the water pump 14, as shown in FIGURE 3.
In operation, with the engine 10 running, the water pump 14 draws water or other liquid coolant from the relatively cool bottom tank 54 of the radiator, through the cooling coil 24, which is immersed in the oil (not shown) in the oil pan 18, so that the temperature of the oil is reduced, and recirculates this coolant through the cooling system of the engine, in a continuous cycle.
Although there has been shown and described a preferred form of the invention, it is to be understood that the invention is not necessarily confined thereto, and that any change or changes in the structure of and in the relative arrangements of components thereof are contemplated as being within the scope of the invention as defined by the claims appended hereto.
What is claimed is:
1. In an internal combustion engine comprising a cooling jacket, a radiator having a top tank and a bottom tank, the top tank being directly connected to said jacket, a water pump having an intake and an outlet, said outlet being connected to said jacket at a point remote from the connection of the top tank with the jacket, means connecting the intake of the pump to the bottom tank of the radiator, and a crankcase: The improvement of a tubular cooling member supported within the crankcase, said cooling member having a first arm connected to the radiator bottom tank at a point remote from the connection of the pump intake with the bottom tank, said cooling member having a second arm connected to the pump intake.

3. In an internal combustion engine comprising a cooling jacket, a radiator having a top tank and a bottom tank, the top tank being directly connected to said jacket, a water pump having an intake and an outlet, said outlet being connected .to said. jacket at a point remote from the connection of the top tank with the jacket, means connecting the intake of the pump to the bottom tank of the radiator, and a crankcase: The improvement of a tubular cooling member supported with the crankcase, said cooling member having a first arm connected to the radiator bottom tank at a point remote from the connection of the pump intake with the bottom tank, said cooling member having a second arm connected to the pump intake, said pump intake consisting of an intake pipe directly connected to the bottom tank of the radiator, said intake pump having a sidewall, said second arm of the cooling member being connected to and opening through said sidewall, said second arm being substantially smaller in diameter than the pump intake pipe.
