EXHAUST AAND WATER DISCHARGE FOR ENGINES.
- pplication @led March 28, 1921. Serial No. 45G,428.
To all whom it mag/concern:
Be it known that I, EARL V. GARA, a citi-v zen of the United States, residing at lBalboa, in the county of Orange, State of California, have invented new and useful Improvements in Exhaust and Water Discharge for Engines, of which the following is a specification.
My invention relates to exhaust and water w discharge construction for internal combustion engines, and is particularly adapted to be used in connection with marine engines.
In engines of the type above described it has been customary to discharge the exhaust l5 products through a pipe leading rearwardlyA fromthe engine along the bottomof the boat and having its exit at the stern thereof a short distance above the water line. It hasy also been customary" to lead the water from the cooling jacket into this pipe to Abe discharged yinto the sea along with the exhaust products. ln this construction an upwardly projecting arch in the shape of an inverted U is formed in the exhaust pipe adjacent the engine, in order that when the boat pitches the water would not run forwardly through said exhaust pipe into the ,cylinders and thereby foul the engine, the pipe from the cooling jacket entering the exhaust pipe at the rear of said arch.
The foregoing described construction has proven objectionable, inasmuch as not only a vast amount of `heat is thrown out into the boat by the arched pipe, to the discomsubjecting the boat to the danger of lires, as the arch at times become red hot, but While the engine is notein operation moisture finds it way thrugh the exhaust pipe into the engine cylinders to the'detriment of the eiiicient functioning of the engine.
It is the object of my present invention to provide a construction which will overcome the above recited objections, by discharging the exhaust roducts as wellas the water Vfrom the coollng jacket at a point high above the level of the sea and at the same time utilizin the water from the cooling jacket for coo ing the exhaust pipe, and so arrangingkthe various discharge pipes that all danger of water backing into the engine cylinder is eliminated. l
A further object of my invention is to provide means whereby the, pump forv supplying 'the engine cooling jacket with water,
' fort of the occupants of the boat, as well as may be readily and conveniently primed should the water in said cooling jacket become exhausted when the engine is out of use, due to a leaky foot valve in the pump.
Other objects of my invention will be dis-A closed in the following description, and pointed out in the claims, and are embodied in the accompanying drawings, in which:
Fig. 1 is a side view of a boat, parts being broken away to show the 4engine and the 65 elements of my invention applied thereto.
Fig. 2 is an enlarged detail sectional View, illustrating more clearly the construction and operation of my invention.
In carrying out my invention, 5 repre- 70 sents a boat, having the bow 6 and the stern 7. rlhe propeller 8 is mounted on the shaft 9 which is driven in the usual manner by the engine 10. The engine 10 is provided with rthe usual exhaust manifold 11, the pump 12 75 which sucks waterfrom the sea to supply the cooling j acket13, and the fuel inlet manifold 14.
My improved discharge construction comprises a tubing 15 of suitable length and 80 diameter which is adapted to be supported in an upright manner and is provided at the top with a water tight cap 16 and at its lower end with a water tight fitting 16. The fitting 16 is provided with a down-85 wardly projecting elbow 17 intothe lower end of which is threaded the end 18 of the exhaust manifold 11. The opposite end of elbow 17 projects upwardly into tubing 15 and threaded into vthe same is a pipe 19 90 of smaller diameter than tubing 15 which forms a continuous passage for the exhaust products. v
The pipe 19 extends upwardly into tubing 15, its upper end being open, and terminating adjacent the lower surface of cap 16, and may be provided with a plurality of perforations 2O as clearly shown in 'F 1g. 2 ofthe drawings.
The cooling jacket 13 of the engine, is ,100 connected to the chamber 21 formed between the outer wall of pipe 19 and the inner wall of tubing 15 adjacent the lower end f of said tubing, by means of a pipe'.y 22 which is provided'with a valve 23; and the upper X05 end of chamber 21 is provided with an outy let opening 24 tapped into the wall of said tubing, into which may be secured the discharge pipe 25 adapted to lead to the outside of the boat at a suitable distance above M0 which in turn starts the pump 12, water is thereby pumped through the cooling jacket 13, thence through pipe 22 into chamber 21. rlhe exhaust products from the e-ngine pass through pipe 18 into pipe 19 and thence through the top of said pipe and the.per forations 20. As the water from the cooling jacket reaches approximately the level of the discharge opening 24 the exhaust products force the Water out through the pipe 25, said products discharging at the same time through said pipe.
By the above described mode of operation it will be seen that the water from the cooling jacket tends to keep the exhaust pipe cool and by the mixing of the exhaust products with the Water and discharging them simultaneously the water `forms a cushion for the exhaust products and thereby deadenS the sound and forms an efficient muiiier. It will also be noted that the force of the discharge products effectively prevents any oi the water from entering the exhaust pipe 19 to foul the engine.
Should the foot valve (not shown) of the pump 12 be defective or leaky, it will be obvious that when the engine is idle the cooling jacket of the engine will become drained and when the engine is again started the pump will have to be primed in order that it may properly function; to Ithis end the valve 23 is provided in ypipe 22 and it' closed immediately after the engine is stopped sufficient wat-er will become trapped in chamber 21 to be utilized for priming the pump when it is again desired to start the engine.
What l claim is:
1. rlhe combination with an internal combustion engine having .a cooling jacket provided with Water inlet and outlet openings and a pump for circulating water through said cooling jacket, of a stand pipe connected at its lower end with said water outlet opening and provided adjacent its closed upper end with a discharge opening, and a second stand ipe of smaller diameter arranged in said first mentioned Stand pipe adapted to exhaust manifold, said second mentioned stand pipe being open at its upper end and extending above said discharge opening.
2. The combination with an internal combustion engine having a cooling jacket provided With Water inlet and outlet openings and a pump for circulating Water through said cooling jacket, of a stand pipe connected at its lower end with said water outlet opening and provided adjacent its closed upper end with a discharge opening, a second stand pipe of smaller diameter are` ranged in said first mentioned stand pipe adapted to be connected with said engine exhaust manifold, said second mentioned stand pipe being open at its upper end and extending above said ydischarge opening, and a valve for closing connection between said stand pipe and water outlet opening.
be connected with said engine 3. rlhe combination with an internal comi bustion engine, of an exhaust pipe connected with the exhaust port of the engine cylinder, the free end of said exhaust pipe opening to atmosphere, a cylindrical water xjacket surrounding the outer portion of said exhaust pipe, said jacket having closed ends, and a valve controlled water passage connected to the lower end of said cylindrical water jacket and to the water jackets of the engine cylinder, said cylindrical water jacket having a discharge passage at the upper' end thereof, the Water from the engine jackets and the products of combustible discharging through said discharge passage.
ln Witness that l claim the foregoin l have hereunto subscribed my name this gth day of March, 1921.
