Application filed December 7, 1920. Serial No. 428.885.
To all whom it may concern:
Be it known that I, SAMUEL W. RUSH- MORE, a citizen of the United States. and resident of Plainfield, in the county of Union and State of New Jersey, have-invented certain new and useful Improvements in Cooling Systems, of which the following is a specification.
My present invention relates to cooling systems adapted for use with internal combustion engines and particularly to those adapted to operate by the boiling and condensing cycle, with the radiator functioning as an upflow condenser. The generic features of construction, the operation, and the advantages of such functioning are set forth in my Patent No. 1,378,724, granted May 17, 1921.
In its preferred embodiment the invention includes a force-feed circulation serially through a heat absorption circuit of radiatmg l capacity barely sufficient, or even insu cient, to continuously cool the motor by Water cooling methods, in combination'with a supplemental induced or thermal circulation through a radiating circuit, arranged,
so to speak, in shunt on the force-feed circulation and adapted to automatically come into play proportionally as the heat evolution in the engine increases and thereby raises the temperature of the discharged. waterf This induced or thermal circulation attains maximum activity when the temperature is high enough to cause free evolution of steam. These circuits may be provided by connecting an ordinary force pump circuit through the space in the bottom of the radiator, preferably with the inlet and outlet so located and relatively arranged that a. very low resistance path is aflorded from the jacket water inlet, across to the outlet which leads to the pump in the Water jacket.
Thus arrangedthe radiator proper is not in series with the water circulation, but is in position to afford a shunt path to which hot Water and steam may escape. arrangement, starting the engine will cause the pump to circulate a small amount of water in substantially closed circuit through pump, water-jacket, piping and .the intermediate low resistance path between inlet and outlet at the bottom of the radiator. This small body of water used over and over again will be heated preferably to boiling point.
As it is desired that the low resistance With this cooling path of the water across the bottom of the. radiator be of relatively small capacity it is evident that when only this part of the radiator is filled, the surplus available for pump leakage and other ordinary losses will become rather small, hence I prefer to when'water in the honeycomb is forced out by steam in the manner described above. The above and other features of my invention may be more fully understood from the following description and the accompanying drawings in which Figure 1 is a side elevation conventionally indicating an internal combustion engine, an air cooled radiator as commonly employed on automobiles, etc, but having one orm of my invention apphed thereto;
Figure 2 is a vertical section of the radiator.
Fig. 1 shows the usual crank case 1 and cylinder block 2 of a four cylinder motor of the automobile t pe, the upper parts of which are enclosed y Water jacket 3. The
The return pipe 19 is connected to the bottomof the radiator, as by flexible joint 23 and downward pipe 24 which, if desired, may be recurved as at 25 so as to enter the radiator through the bottom.
The radiator is specially designed so that the amount of water circulating at the bottom of the radiator may be relatively small, and so that the honeycomb may act almostentirely as a steam condenser, yet with provision for a reasonable reserve supply of Water to compensate for leakage and other losses. As shown in Fig. 2 the honeycomb cooling area is considerably reduced, this being made possible by the above referred to increase of efiiciency due to working at higher initial temperatures. The space so saved at the top of the radiator is utilized as a reservoir 30 communicating with the honeycomb compartment through standpipe 31. This reservoir 30 communicates with the intake of the pump through pipe 32 which may be provided with a cock 33 through which water may be drawn ofl'. Flow of water from this source downward from the pump, through conduits 8, 6, 5 into the bot-- tom of the radiator, is preferably prevented by means of the check valve at 7. When the ordinary centrifugal pump is employed, this check valve also operates to prevent blowing back of water from the jacket'into the bottom of the radiator, if the engine is stopped while hot enough to generate considerable quantities of steam.
As shown in these Figs. 1 and 2, the discharge inlet is in the form of anelbow casting 26 directly confrontin a similar casting 5, which ,is the intake Tor pipe 5 which leads to the pump. This affords a s ecially engine at sufficient speed, and until a further de ite amount has collected in the bottom of the radiator. Thereafter water drawn from reservoir through pipe32 and thus getting into circulation, may accumulate in the bottom of the radiator to a certain extent, but whenever the accumulation becomes too great the steam coming in through 26 and rising through the vertical passages will tend to projectthe excess water up through pipe 32.
I claim- 1. In a cooling system for internal combustion engines, a force feed water circulating system of small heat radiating capacity serially including a water jacket, a water outlet conduit from said jacket, a water container to which said outlet is connected, and a return conduit including a pump between said container and jacket, in combination with an air cooled element of large radiating capacity above said water container, interposed between it and an outlet for escape of air, steam and hot water; and a reservoir interposed between the air cooled element and the air outlet, arranged to trap water driven through the air cooled element in the operation of the device, and means for returningthe trapped water to the cooling water circuit.
