INTERNAL COMBUSTION ENGINE Filed Dec. 28, 1929 Y nzxmf'or HIYar/ZZZ www j MN,
Patented Feb. 24, 1931 UNITED STATES PATENT OFFICE- LEWIS H. MORRILL, F FORT WAYNE, INDIANA, ASSIGNOR T0 INTERNATIONAL HAR- VESTER COMPANY, A CORPORATION OF NEW JERSEY IN TERNAL-COMBUSTION ENGINE Application led December 28, 1929. Serial No. 417,052.
This invention relates to an internal combustion engine, and particularly to a liquid cooled head construction therefor.
The object of the invention is to provide an improved head construction having water jacket spaces to enable circulation at high velocity over the cylinder head walls, around the intake and exhaust pipes and around the valve guides, in a manner best adapted to transfer the heat from these parts and prevent the formation of steam pockets or bubbles.
Briefly, this object may be achieved in the provision of an integrally cast head having appropriate passages, water jacket spaces,
and deilecting walls for achieving the desired results. It is to be understood that the circulation in the head is impelled by a pump from the engine and that such circulation in the head is entirely independent of and separate from the water cooling system for the engine block. As a result, it is possible to keep the water in the block at a uniform temperature, and the separate circulating system in the head is effective quickly totransfer the heat from the head, which is highly desirable in maintaining the volumetric eiliciency of the engine.
In the drawings showing an illustrative embodiment of the invention by way of example,-
Figure 1 is a sectional view along horizontal planes, as viewed looking down along the section line 1-1 in Figure 3;
Figure 2 is a fragmentary view showing only one end of the head, the same being a section taken along vertical lines, as seen along the line 2 2 of Figure 3; and,
Figure 3 is a general transverse cross sectional view. j
The block of the engine is shown at 10, having the usual water jacket 11 surrounding the cylinder Wall 12. An inlet water manifold pipe 13 extends longitudinally along one side of the engine and is secured in any appro-v priate manner to the block 10, the said manifold being in communication with a number of passages 14 that lead upwardly, as best shown in Figure 3.
The improved integrally cast cover or head for the block is generally indicated at 15, the same including cylinder head walls 16 and inlet and exhaust pipes 17, said pipes in a conventional manner communicating with the cylinders through the head 16. The conduits 14 communicate with openings 18 in the bottom of the cover 15, and surrounding each of these openings 18 is a vertical wall having two angularly related extensions 19, there being a cover plate 20 fitting over the wall extensions and arranged in parallelism with the top side of the wall 16 over the cylinders or compression chamber. As best shown in Figure 1, a supplementary, vertical wall 21 is provided having angularly related extensions 22. Thus, it will be seen` that the walls 22 and walls 19 form in effect flared nozzles for directing the cooling liquid around the inlet and exhaust pipes 17 and over the cylinder head walls 16 at increased velocity, thereby serving best to wash these surfaces, quickly to transfer the heat therefrom and to revent the formation of steam pockets. It 1s to be noted that the nozzle effect is augmented, as best shown in Figure 3, by the close arrangement of the cover wall 20 with respect to the cover wall 16. This is also very well shown in Figure 2.
alve guides are shown at 23, and, due to the inclined upper wall 24 and because the heat laden water naturally rises anyway, it passes around these valve guides 23 to kee the same cool. The wall 24 over the pipes 1 then runs in a horizontal direction and forms a bottom Wall or floor 25 for an outlet manifold 26, there being, at suitably spaced intervals in said floor 25, a plurality of holes 27 which receive the water from the jacket spaces already disclosed. This water then passes out through an exhaust outlet 28 and 90 then is led in any appropriate manner back to a radiator or some other similar heat dissipating arrangement.
From this description it will be seen that a separate, pump impelled circulating system is provided for an engine head, which is independent of and separate from the Water jackets of the engine block. The holes 27 are so arranged that they uniformly distribute the water'from the head into the outlet manifold 26. The feature of casting this manifold integrall with the head insures the maintenance o a large volume of water over the exhaust ports and carries the hot water and steam away rapidly, thereby dissipating the heat from the combustion and valve port surfaces.
From this description it can now be seen that a simple and effective structure has been provided which achieves all of the desirable objects of the invention.
It is the intention to cover all such changes and modifications as do not materially depart from the spirit and scope thereof, as is indicated in the following claims.
What is claimed is:
1. A liquid cooled head for an internal combustion engine, said head comprising cylinder head walls, intake and exhaust pi es in communication therewith, valve gui es, there being jacket spaces for the cooling liquid around said members, an inlet manifold for the liquid, and angularly related deiecting walls for causing the liquid to wash over the cylinder head walls and around thg intake and exhaust pipes.
