INTERNAL COMBUSTION ENGINE Filed Sept. 29, 1930 2 Sheets-Sheet l WWI/22222 ,5. W/ie/aiz INVENTOR ATTORNEYS y 1934. w. B. WHELAN 1,958,156
INTERNAL COMBUSTION ENGINE Filed Sept. 29, 1930 2 Sheets-Sheet 2 Wfi/iam B. W/ze/azz INVENTOR ATTORNEY$ Patented May 8, 1934 2 Claims.
My invention relates to improvements in internal combustion engines, and it consists in the combinations, constructions, and arrangements herein described and claimed.
An object of my invention is to provide an internal combustion engine in which novel means is provided whereby the liquid in the water jacket is caused to circulate from the top of the engine downwardly around the oil pan and to the radiator associated with the engine.
A further object is to provide a device of the type described in which the cooling liquid circulates from the warmest parts of the engine through means associated with the oil pan in such a manner that the oil within the pan maybe heated during cold weather, and in which the construction is such that a more uniform temperature may be maintained.
A further object is to provide a device of the 20 type described incorporating novel means whereby the engine will retain a maximum high temperature for a maximum length of time after the engine has been stopped.
Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.
My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is a sectional view of an internal'combustion engine embodying my invention,
Figure 2 is a sectional view taken along the line 2-2 of Figure 1,
Figure 3 is a side elevation, partly in section, of a slightly different form of my invention,
Figure 4 is a perspective view, partly in section, of another form of my invention, and
Figure 5 is a sectional view of a portion of the 40 structure shown in Figure 4.
In carrying out my invention, I make use of an internal combustion engine 1 comprising a cylinder block 2 provided with a cylinder head 3 and a crank case 4. The crank case comprises in part an oil pan 5. Broadly, such parts are old in the art. In the present instance, I'have shown the cylinder block 2 as being provided with a liquid passageway 6 which communicates with a similar passageway 7 around the oil pan. The 50 passageway '7 extends upwardly on the opposite end of the engine and communicates with a conduit 8 which is operatively connected with a radiator 9. The conduit 8 connects with the upper end of the radiator. A second conduit 10 is operatively connected with the lower end of the radiator and a pump 11. The side of the cylinder block is provided with an inlet opening 12 which communicates with a conduit 13 having communication with the pump 11. The bottom of the oil pan is provided with a sump 14 having a plug 15. One end of the engine is provided with a bafile plate 16.
In operation, the pump 11 functions whenever the engine is running. The pump may be connected with the engine by any suitable means not shown. The pump causes a circulation of the cooling fluid through the engine and the radiator, as indicated by a series of arrows 17. The crankcase may be provided with suitable bearings 18 for supporting the crankshaft 19. A detail of this bearing is shown in Figure 2. The construction is such that the cooling liquid is caused to circulate around the hearing. In the ordinary device, the heated liquid passes directly from the engine to the radiator. In the present device, the liquid in the water jacket tends to circulate downwardly upon the right-hand side of the engine, as when viewing Figure 1, around the oil sump 14, upwardly upon the opposite end of the engine, and then to the radiator. Water from the radiator 9 is passed into the water jacket of the engine through the opening 12.
An important feature in connection with my invention is the fact that the oil within the oil pan is heated by reason of the circulation of the cooling fluid. In addition to this, the engine remains at a maximum high temperature for a relatively long time after the engine has stopped running. This is a particularly important feature in extremely cold weather. The cooling liquid must of necessity pass around the entire engine before it can be passed to the radiator.
In Figure 3 I have shown a slightly different form in which the water jacket conforms to any of the standard constructions with the exception of a pair of baffle plates 20 and 21. The plates are arranged in such a manner that the liquid from the engine must pass over the bafiie plate 20 and down below the baiile 21 before it passes to the radiator. with this form.
A further modified structure is shown in Figures 4 and 5. One end-of the engine in this form is provided with a pair of compartments 22 and 23. These compartments are placed in communication through the medium of a U-shaped tube 24. The ends of the tube 24 are connected with the compartments 22 and 23. The compartment 22 is provided with an opening 25 which places the compartment in communication No pump is used in connection with the water jacket proper. The compartment 23 is provided with a conduit 26 which leads to the radiator, not shown. This conduit is connected with the upper end of the radiator while the lower end of the radiator communicates with the water jacket of the engine through the medium of a conduit 27. A suitable pump 28 may be employed in connection with the conduit 27 for circulating a cooling fluid through the engine.
The pump employed may be any one of the many types which are used in the art. The specific pump construction and the manner of connecting the pump with the motor are well known in the art and therefore require no detailed description.
I claim:
1. An internal combustion engine comprising a water chamber in the upper portion thereof, a crank case having an oil reservoir therein, a water circulating pump operated by said engine, a radiator, a conduit for conveying cooling water from the lower portion of said radiator to the lower portion of said chamber, and a conduit extending downwardly from the upper portion of said chamber into heat transfer relation with said oil reservoir and thence to the upper portion of said radiator for conveying circulating water from said engine to *said radiator during the operation of said engine and pump, said downwardly extending portion of said last mentioned conduit serving to retard the thermo-siphonic circulation of water from said engine to said radiator when said engine and pump have stopped.
2. An internal combustionengine comprising an engine block having a waterchamber, a crank case having an oil reservoir therein, a conduit communicating with the water chamber at the upper end thereof at one end of the block and extending downwardly into heat transfer relation with said reservoir, thence upwardly and communicating with the radiator at the upper portion thereof, and a water conduit leading from the lower end of the radiator to the lower portion of said water chamber.
