MUFFLING- SYSTEM FOR EXPLOSION-ENGINES.

To all whom it may concern` Be it known that I, ALEXANDER WINTON, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Mutlling Systems for Explosion-Engines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in mnftling systems for explosion engines, the object of which is to make an effective and cool mailling system especially intended for motor boats using explosion engines.

In the accompanying drawings Figure 1 is a side elevation of a portion of an explosion engine showing the improved system applied thereto. Fig. 2 is an end elevation showing theexhaust pot in section. Fig. 3 is a vertical section of the exhaust pot, the section taken at right angles to that shown in Fig. 2. Fig. 4 is a cross sectional view on the line 1-4 of Fig. 3, looking in the direction indicated by arrow.

Referring now to the drawings7 1 indicates the cylinders of an explosion engine, 2 the water inlet pipe which is connected with the cylinders in any suitable manner for circulating cool water around the explosive ends of the cylinders, and as here shown connection is made by a plurality of lateral pipes or connections 3. A pipe 4t is the outlet pipe for the water after it has circulated around the cylinders and this pipe is connected with the cylinders by lateral passages, connections or pipes 5. A suitable manifold 6 is connected with a carbureter (not shown) and with the explosion ends of the cylinders in the usual way to furnish the explosive mixture. Thus far `only the ordinary construction of explosion engines has been described and the present improvement will now e set forth.

Extending across the sides of the cylinders 1, is an exhaust pocket 7, which receives the exhaust from the cylinders 1. This exhaust pocket is connected with a vertically arranged exhaust pot 8 through the medium of a pipe or connection 9. This pipe or connection 9 extends upward within the exhaust pot 8, as shownat 10 and has its upper end doubled and extends downward, as

shown at 11, thus constituting an inverted U-shaped upper end. Located within this pot and below the outlet end 12 of the pipe Specification of Letters Patent.

l() is a diaphragm or baille partition 13, which partially closes the pot 8. This partition 13 is inclined, as shown in Fig. 3, and the exhaust gases from the .motor are projected from the end 12 against this baille pla-te or partition, which diffuses the gases within the pot and prevents them from being projected straight downward therein. The lower end of the pot 8 is provided with the out-let pipe 11i, which has its inner end 15 extending downward within the pot and its outer end extended outward. This outer end will extend to the outside of the hull of the `vessel (not shown) in any suitable manner and in any suitable relation to the sea level. An adjustable gate valve 16 is located within this pipe 111-, for the purpose of varying the sizes of the outlet as desired. The upper' end of the pot 8 has an outlet 17, and this outlet is provided with a gate valve (not shown) of the saine form as t-he gate valve 16, and is adjustable through the medium of a suitable wheel 18. This gate valve controls the passage of the exhaust gases from the pot S, through the pipe 19, which pipe will extend into the ventilator stack (not shown) of the vessel.

The lower end of the pot 8 will be so l0- cated in the boat that the inner end 15 of the pipe 1st will be below the sea level, although this may be higher or lower, though, preferably, as shown. The water outlet pipe 4, from the water circulating system of the engine passes into the upper portion of the pot S, through the pipe 20, and this connection is preferably located above the exit end 1Q, through which the exhaust gases enter into the pot. From this it will be understood that the circulating water from the engine passes into this pot and finds its outlet through the pipe 14. The circulating water passing into the pot serves to cool the exhaust gases and the pot and this is increased by reason ot the exhaust outlet 12 being below the water inlet 20. By means of the two gate valves 16 and 17,`they can be adjusted so that the exhaust may fully or partially pass through the Ventilating stack. With the gate valve 17 closed and the valve 16 at sea level open, all the exhaust finds its exit close to or below the water line as desired. In practice, preferably the top valve 17, is left partially open and the major portion of the exhaust escapes under water. Upon stopping the engine there is no back siphon action as the top valve is open and there is no tendency to vacuum by reason of condensation or cool ing of the exhaust pot. The effect of the combination is a cool noiseless exhaust.

Having thus deseribedthe invention, what is claimed and desired to secure by Letters Patent isl. The combination with an explosion engine, having a common manifold, of an exhaust pot in Communication with said manifold, the said exhaust pot having an outlet in its upper and also in its lower end, a water circulating cooling system for the engine having communication with the exhaust pot at a point between the two said outlets, valves for operating said outlets, whereby the exhaust gases may be passed out of the upper opening and the water out of the lower opening or both the exhaust gas and water together out of the lower of said openings, the water circulation through the said pot not being disturbed in either event.

2. The combination with an explosion engine, having a Common exhaust manifold, of an exhaust pot having communication with said manifold, said communication comprising a virtually inverted U-shaped tube having its lower end in communication with the exhaust manifold and its upper end open and within the exhaust pot, a baffle plate arranged below the exhaust inlet into the said pot, said'pot having outlets in its upper and lower ends and valves for opening and closing said outlets for the purpose 'described.
