SYSTEM OF ENGINE-COOLING.
Specification of Letters Patent.
Patented Nov. 24, 1914.
Original application filed May 18, 1912, Serial No. 696,976. Divided and this application filed May 18, 1913. Serial No. 768,547.
To all whom it may concern:
Be .it known that we, HENRI G. CHATAIN and TVILLIAM E. Van PLANCK, citizens of the United States, residing at Erie, county of Erie, State of Pennsylvania, have invented certain new and. useful Improvements in Systems of Engine-Cooling, of which the following is a specification.
The present application is a. division of our application, Serial No. 696,976, filed May 13, 1912, which division is made under the requirements of the United States Patent ()ffice.
The present invention relates to motor cars in which an internal combustion engine is employed for propelling purposes, and more especially for such cars Where the engine drives an electric generator and the latter supplies current to motors mounted on one 01 more of the trucks. The engine and generator are mounted in the front end of the car, the remainder being devoted to passengers, baggage, etc. In such an equipment :1 means must be provided for dissipating the heat of the circulating water that passes through the jackets of the engine cyl nders.
The object of our invention is to improve the construction and arrangement of such cooling means wherebv the engine will be effectively cooled and this without the use of a circulating pump or pumps.
For a consideration of what we believe to be novel and our invention, attention is directed to the accompanving description and claims appended thereto.
In carrying out our invention the cylinders and exhaust valves of the engine are provided with suitable iackets to permit the circulation of cooling water. These jackets are divided into right and left hand groups or sets which are connected by flexible pipes or hose of large diameter to a two-part radiator that is mounted on and conforms to the shape of the roof of the car as nearly as possible. Such an arrangement has the advantage that a very large surface area. for cooling may be provided. By locating the radiator on the roof it is practically free from danger of injurv: is out of the path of dust and dirt, and is subject to the maximum. cooling effects of the currents of air when the car is in motion.
In the accompanying drawings which illustrate one of the embodiments of our invention, Figure 1 is a diagrammatic view of the cooling system; Fig. 2 is a. view partly in section and partly in elevation of an indicator to show the level of water in the radiator; Fig. 3 is a longitudinal sectional view showing one of the headers or the radiator and the overflow tank, and Fig. 4 is a detailed view showing the arrangement of the conduits for conveying water to and from the cooling jackets of the engine cylinders.
Referring to Fig. 1, 10 indicates the floor of the cab containing the apparatus, 11 a side wall thereof, and 12 the curved roof. 13 indicates the main internal combustion engine for propelling the vehicle. It is provided with cylinders 14 and 15 arranged in sets of four each. 16 indicates a small internal combustion engine for driving a generator for lighting the car and driving an air pump, the latter supplying compressed air for starting and braking, etc. The rediator comprises two principal parts or elements, one on the right-hand side and the other on the left-hand side of the car, said radiator being located above the roof and corresponding approximately in shape to the curvature thereof. Each element is pro' vided with a horizontal header 1? located at approximately the center of the car roof. and a smaller horizontal header 18 located near the side. said headers extending longitudinally of the car. Connecting these headers are rows of outer tubes 19 and rows of inner tubes 20. Onlv two of these tubes in each part of the radiator are shown. but it is to be understood that a multiplicity of such tubes is provided. Each tube is provided with radiating fins 21 of suitable construction. Cooling water after leaving the radiator flows from the lower header 18 by a flexible pipe, such as a piece of rubber hose 22, to the jackets on the left-hand set of the engine cylinders. It is necessary to provide a flexible connection at this point on account of the fact that the engine 13 has a certain limited amount of movement independentlv of the car body. The water after circuiating through said jackets flows upwardly bv connection through the pipe 93 to the header 17. The right-hand set of ongine cvlinders is similarly connected to the right-hand section of the radiator.
In Fig. 4 one set of engine cylinders is shown in side elevation. They are provided with jackets of any suitable construction and circulating water is admitted thereto by the vertical pi ms 24 and the horizontal pipes 25 and 26. 21 indicates the pipes that connect the casings of the exhaust valves. The pipes 24 are united at the top by theconduit 28 made in the form of a Y and to which the flexible pipe 22 is connected. The circulating water is discharged from the jackets by the conduits 29 and 30 which are connected to conduit 31, Fig. 1, also made in the form of a Y. This conduit is connected by a piece of rubber hose or pipe 23 with the header 1?, F ig. 1, and through which the heated water flows upwardly by convection. Referring to this latter figure the arrows indicate the direction of the flow of the circulating water through the jackets. 32, Fig. 1, indicates a pipe that forms a downward continuation of the conduits 24 and which is connected with the filling connection 33 that is under the control of a valve 34. Faid connection 33 can be used either for filling the cylinder jackets and the radiator or for draining them by opening the valve 34. 35 indicates an equalizing pipe for the engine jackets. This contains a valve 36. \Vhen the valve is open the water levels in the parts of the radiator will be equalized through this connection and the pipes 32. lVhen it is closed one set or group of engine jackets can be cut out of service. Such an arrangement is desirable when for any reason one section of the radiator is inj ured or something happens to the operating mechanism of one-half of the engine. In other words, this permits of a partial operation of the car instead of total failure as would be the case if the cooling system entirely failed.
In order to avoid overheating incident to low water in the radiator an indicator is rovided of the character she am in Fig. 2 1n which 40 indicates a tubular chambered member containing a body of water. Supported by the water is a hollow metal float 41 that is connected to a vertically movable tube 42. Located within this tube is a second and fixed tube 43 which rises considerably above the predetermined maximum level of the water. Extending through the tube 43 and attached to the outer end of the float tube 42 is a small rod 44, to the lower end of which is attached an indicator 45 that by comparison with a flat plate 46 indicates the position of the float 41 in the float chamber, and, therefore, a level of the water therein. Preferablv the plate 46 is painted with different colors so that the attention of the operator will be more read ily attracted, particularly when the water is getting low. As shown, the tubular mem- Der 40 extends upwardly through the header 17 and also through the overflow tank 47 which is mounted on top of the header. 19 and 20 indicate the tubes extending from the upper to the lower header. The lower end of the tubular member 40 is perforated at 48 to permit water to enter the float chamber from the water chamber 49 of the header. A guard 50 is also provided which stands in front of the opening 48 and acts to prevent the movement of the water in the chamber 49 due to car movements from directly affecting the float.
Referring to Fig. 3, we have shown one of the headers 17 in longitudinal section, the tube openings being omitted for simplicity. In order to further improve the operation of the cooling system an overflow tank 47 is provided whose cubical contents are preferably a little greater than those of the water jackets of the engine so that in the event of the engine becoming overheated and generating steam an amount of water equal to the contents of the jackets may be discharged from the headers into said overflow tank. The transfer of water from one tank to another takes place through the openings 51. Thisoverflow tank is also useful when the car is climbing a steep grade because water that might otherwise run out of the radiator through one of the filling holes at the top is caught in said tank and returned to the radiator as soon as the conditions become normal.
The water jacket 52 of the auxiliary engine 16, Fig. 1, receives its supply from the pipe 32 of the right-hand set of engine jackets. After passing through the acket 52 the water flows by the pipe 53 to the upper right-hand header 17 from which it flows through the radiator tubes 19 and 20 to the right-hand lower header 18 and thence through the pipe 22 back to the jackets on the right-hand set of engine cylinders.
In accordance with the provisions of the patent statutes, we have described the principle of operation of our invention together with the apparatus which we now consider to represent the best embodiment thereof; but we desire to have it understood that the apparatus shown is only illustrative, and that the invention can be carried out by other means.
