Application January 19, 1951, Serial No. 205,373
(El. Mil-52) 1 Claim. 1
This invention relates to internal combustion engine exhaust mufiiers and more particularly to those types, that are combined with the cooling water used in conjunction with the water jacket of the engine for maintaining the temperature thereof at a safe and predetermined level.
The conventional muffler used in connection with-an internal combustion engine exhaust of the marine type has the objection of being noisy and erratic. duced into the exhaust pipe in connection with its operation is subject to sudden spurts that are a source of danger while at the same time reducing the eifectiveness of the device. In this invention a unique type of mufiler is employed. It is adapted to hold an ample quantity of water within it to cushion the exhaust and eliminate noisy reactions, while at the same time cool the exhaust gases, extinguish sparks and flames thereof and reduce the vibrations that are liable to be incurred in the operation of the engine. It consists primarily of a housing with baffles arranged therein, and with flanges or connections for coupling it to the incoming exhaust line of the engine at one wall and to the outgoing line leading from another wall.
It is therefore an object of this invention to provide a new and improved exhaust mufller that will avoid one or more of the disadvantages and limitations of the prior art.
Another object of the invention is to provide a new and improved exhaust mufiler for marine type internal combustion engines that will provide a cushion and water seal for the gases exhausted therethrough and a uniform fiow of the cooling water to the outside.
Another object is to provide a new and improved exhaust mufiier for an internal combustion engine having a water cooling system exhausting into the gaseous exhaust line to intermingle with the exhaust gases and a gas bleeder from the muffler to the outside, that will be effective in action, simple in design and economical to manufacture.
Other objects will become apparent as the invention is more fully described.
For a better understanding of the invention and its objects, reference is made to the accompanying drawings, which in conjunction with the following description outline a particular form of the invention by way of example, while the claims emphasize the scope thereof.
In the drawings:
Figure l is a plan view of an exhaust muffler embodying this invention;
Further the cooling water introl Figure 2 is a View of the inlet side of the muffler;
Figure 3 is a'view of the exhaust *side of the mufller; and
Figure 4 is a sectional view on line 44 of Figure 2; and
Figure 5 is a'sectional view on line 55 of Figure 4.
Similar reference characters relate to similar parts throughout the drawings.
In the drawings, l0 is a housing in one piece and of hollow form having a cylindrical contour. its interior chamber l l is also of cylindrical form with an elbow I2 extending therein and downwardly turned, with its lower inlet port l3 positioned above the bottom wall sufficiently to permit a suitable flow of water and gases from the chamber H to pass through its exhausting and upper port M. The port [4 is surrounded by a flange integrally connected with the housing and drilled and tapped at l6 for bolts l8 to hold the flange of a pipe I! leading to the outside in which the exhaust line terminates. The outlet port i4 is located about centrally, in the housing, and is below the level of the inlet opening or orilice port 28 to which the exhaust pipe [9 from the engine is attached. The port is surrounded by a flange 2i and provided with tapped holes 22 to receive the bolts 23 used for attaching the exhaust line I9 from the engine. A drain hole 25 closed normally by a plug 26 is provided in the lower wall of the housing and enables access to the interior chamber I l. A vent passage 21 leads from the upper area of the chamber ll then down through a tube 28 and out of its orifice 30 into the port I l. The orifice 30 is provided with a baffle lip iii to prevent the water flowing through the port [4 from blocking and closing the end of the tube 28 which creates a syphoning ei fect to pull the gases through from the upper portion of the chamber II and out through the port M to the outside. The upper end of the tube 28 is closed with a pipe plug 63 for cleaning and inspection purposes. When the engine is not running the vent passage 21 also serves as a bleeder for vapors and other gases that may collect in the cylinder or internal portion of the engine, muiiier, or its other accessories. These gases are highly inflammable and are trapped in the system when the conventional muffler for use in marine work and the like is used, and the gases are often the cause of fires. The lower inlet port I3 is approximately one-fifth larger than port 14.
The operation of the device is simple. The
exhaust gases and cooling water when the engine is running pass through the line I9 from the engine, through the inlet port 20 and into the chamber H. They twirl about and allow the water and gases in excess of the volume of the chamber to spill out of the chamber il through the lower inlet port l3 and up through the elbow l2 and then through outlet port [4 to the outside. When the engine is running the water level in the chamber H is at the high water line 29 and when the engine is not running the water line falls to line 62. When the water falls to the line 62 it retains sufficient water in the chamber H to cushion any discharges of hot gases from the mufiler and cools them and prevents their passing directly out to the atmosphere without first passing through the water which also deadens the sound. When the water is at line 92 any accumulation of inflammable gases passes out through the vent 21 as described. The device has no moving parts to require repairing and is simple in construction.
While but one general form of the invention is shown in the drawings and described in the specifications, it is not desired to limit this application for patent to this particular form, as it is appreciated that other forms of construction could be made that would use the same principles and come within the scope of the appended claim.
Having thus described the invention, what is claimed is:
A mufiler for exhaust gases comprising a housing having a hollow chamber therein, said housing also having an inlet port and an outlet port, the inlet port having its axis on a higher level than the axis of the outlet port, an elbow in the housing having one end connected to the outlet port and its other open end being turned down and spaced from the bottom of the housing, and the lower edge of the outlet port being on a higher level than the lower open end of the elbow, whereby Water admitted in the housing with the exhaust gases through the inlet port reaches its lower level along a plane including the lower edge of the outlet port which plane is above the lower open end of the elbow, whereby the exhausts gases admitted through the inlet port and passing out through the outlet port are always cushioned and cooled through a body of Water, a passage for venting the housing, said passage having a port opening in the upper end of the housing and a port opening adjacent the outlet port, and a bafile in the vicinity of the last mentioned port opening to allow the flow of water upwardly in said passage.
