WITNESSES ATTORNEYS Patented Dec. 3t), 1924.
SIDNEY LEE CARE, 01* BAY CITY, TEXAS.
lvlUl FLER FOR INTERNAL-GOIKBUSTIGN ENGINES.
Application filed January 7, 1922.
To all whom it may concern:
Be it known that I, SIDNEY LEE CARR, a citizen of the United States, and a. resident of Bay City, in the county of Matagordzu in the State of Texas, have invented certain new and useful Improvements in Mutllers for Internal-Combustion Engines, of which ill) the following is a specification.
This invention relates to a mufiier for internal combustion engines.
Among the objects of the invention is to provide a muliler which freely permits the escape of gases to the ati'i'iosphere from the exhaust or an internal combustion engine; which will silence the report of the exhaust of an internal combustion engine to a high degree; and which will not cause back pressure of the gases escaping therethrough.
It is also an important objectof the invention that the mulller be extremely simple in construction and inexpensive to manufacture.
The invention is illustrated by way of ex ample in the accompanying drawings, in which Figure 1 is a side elevation of a mnfiler constructed in accordance with the present invention,
Figure 2 is a bottom plan view of the same,
Figure 8 is a detailed perspective view of a section ol the perforated portion of the muffler, and
Figure l: is a transverse sectional view oi. the same.
Referring to the drawings more particularly, the inutl'ler consists in a pipe I which is of relative large diameter and comprising the straight portion 10 and the upwardly bent portion 11. The rear end portion 12 of the st sight portion .10 is perforated upon its under side, said perforations being indicated by the reference character 13 and, as best shown in Figure 2. gradually increase in number toward the rear end of the pipe portion 12. Also the rear end of the straight portion 10 is formed with a closure as indicated at 14.
Serial No. 527,652.
It may be here mentioned that the for ward end portion 11 of the mulller may be connected in any suitable manner to the ex:- haust manifold of an engine and the nuillficr serve for all the ditl'erent cylinders ot the engine. Also any suitable means may be used for supporting the rear end ot the mulller.
In the operation or the present device the gases pass through the forward portion 11. of the pipe 1 and then into the straight section 10. The gases begin to escape through the small holes or perforations 13 soon at ter entering the straight portion 10 and are permitted to escape to the atmosphere botore reaching the rear end of the pipe l". The gases es :ape freely and do not cause any back pressure upon the engine exhaust. Also by experience it has been found by this particular arrangement and construction o'li mulller that the report of exhaust from the engine is entirely silenced.
It should be here pointed out that it is quite important that the rear end of the pipe 10 be provided with a large number of perforations 13 for the reason that these perforations break up the discharge gases into small parts belore omitting the same to the atn'iosphere and thus reduce the noise of the explosions in the associated internal coinhnstion engine.
lVhat I c inn is:
A iuutller for internal combustion engine consisting in a pipe. one end being adapted to be connected to the exhaust manifold of an internal combustion engine and its other end closed and said pipe having a perforated portion extending longitudinally thereof from its rear end to a point considerably forward thereto. and said perforations being distributed over the lower half of the pipe and graudally increasing in nu1nher, the perforated area of the pipe being progressively increased in width from the Forward end toward the rear end of the pi e.
