OF BELOIT, WISCONSIN.
1 Specification of Letters Patent.
Patented July 19, 1910.
Application filed December 3, 1909. Serial No. 531,133.
1'0 all whom it may concern:
Be it known that I, THORMOD Oman, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Cooling Systems for Internal-Combustion Engines, of which the following is a specification.
In internal combustion engines the end of the cylinder in which compression and 6X-' plosion occur is subjected to more heat than the opposite end; consequently the explosion end of the cylinder expands to a greater extent and the piston fits more loosely in said end of the cylinder than in its opposite end, which results in a loss of compression and power.
The object of this invention is to provide an improved cooling system for internal combustion engines, which is arranged to have a greater cooling effect upon the explosion end of the cylinder than upon its opposite end, so that the cylinder shall be kept uniform in size throughout its length at all times.
The invention also relates to the various other improvements and advantages hereinafter set forth.
In the accompanying drawings, Figure 1 is a sectional view showing a cooling .ap paratus embodying my invention applied to the cylinder of an internal combustion engine, the base of the engine being broken away and the greater part of its mechanism being omitted. Figs. 2, 3 and 4 are sections on lines 2 2, 3 3 and 4 4, respectively, of Fig. 1.
The embodiment which I have chosen for the purpose of illustrating the invention herein comprises a jacket 1 surrounding the engine cylinder 2., said jacket in this instance being integral with the base 3 of the engine. The cylinder 2 may be removable from the jacket, if desired, in order to permit of replacing said cylinder-in case it should accidentally become damaged. Within the jacket 1 is a partition 4 which separates said jacket into two compartments 1 and 1 which may be termed a forward compartment and a rear compartment, respectively.
The means for holding the cylinder in place in the jacket 1 comprises an outstanding annular flange 5 upon one end of the cylinder arranged to engage an inwardlyextending annular flange 6 formed in the adj acent end of the jacket 1. A head 7 closes the said ends of the jacket and cylinder, said head being held in place by means such as screw studs 8 engaging said head and the jacket 1. The head 7 may have suitable inlet and exhaust passages 9 and 10 therein, and said passages may be controlled by any suitable valve mechanism. Within the head 7 is a chamber 11 which is in communication at all times with the compartment 1 in the interior of the jacket 1 through a plurality of passages12 in the flange 6.
Positioned abovethe jacket 1 and secured thereto is a reservoir or convection chamber 13 which is open at its bottom and communicates with both of the compartments 1 and 1 A tank 14 preferably located in or upon the base 3 of the engine below the compartment 1 communicates at its upper end with the compartment 1 of the jacket 1. The lower endof said tank 14 is connected with the chamber 11 in the head 7 by pipes 15. 16 is a cock for draining the system of the cooling medium. The end of the jacket 1 opposite the head 7 fits closely about the cylinder 2, suitable packing 17 being inserted between the cylinder and the jacket in order to form a fluid-tight joint between said parts.
Then the engine is running the explosion and 2 of the cylinder 2 tends to become hotter than the other end. The cooling medium in the compartment 1 of the jacket 1 is thereby heated and rises into the reservoir 13. This action causes a movement of the cooling medium in the tank 14 through the piping 15 into the chamber 11, directly against that portion of the head 7 which closes the end of the cylinder, and thence along the combustion end 2 of the cylinder into the compartment 1 of the jacket. From the reservoir 13 the cooling medium flows downwardly through the compartment 1 of the jacket and into the tank 14, thus completing the circuit.
It will be seen that the cooling medium is first drawn into the chamber 11 in the head 7 where it cools not only the head of the cylinder but also the fuel inlet and exhaust valve mechanism. By cooling the combustion end 2 of the cylinder more than the other end, said end 2 is prevented from expanding more than the other end, and the piston therefore fits the cylinder fluidtightly at all points. When the combustion end of the cylinder is heated to a higher temperature than the other end, the piston also expands unduly and hence fits the cooler end of the cylinder so tightly that the lubricant is driven before the piston to a point where it is of no use, the result of which is that the piston is insufliciently lubricated, moves with excessive friction, heats the parts, wears rapidly, and unnecessarily consumes power. By using the cooling system herein disclosed these disadvantages are entirely eliminated.
I would have it understood that I do not limit myself to the construction herein disclosed, for various modifications will occur to those skilled in the art.
I claim as my invention:
