MUFFLER.
To all whom it may concern:
Be it known that I, SAMUEL FORNEY,
acitizen of the United States, residing .at Pulaski, in the county of Pulaski and State .Of Virginia, have inventedcertain' new'and useful Improvements in Mufflers, of which the following is a specification.
My invention relates to improvements n automobile muffiers, and has for its leading object the provision of an improved'muffler which will reduce to a minimum the back pressure and the noxious smell and smoke of the gases and consequently will but slightly retard or impede the operation of the engine but whichwill thoroughly and satisfactorily break up the compact gases discharged from the cylinders to cause said gases to empty into the outer air with practically no sound, smell or smoke.
The further object of my invention is the provision of an-improved muffler for automobiles which will-serve to deaden the noise of the explosion and eliminate smell. and
.smoke by mixing with the exhaust gases and which will regulate the quantity of air according to the speed at which ,the automobile is traveling and will consequently be of equal efficiency and have but slight back pressure at all times irrespective of the speed of the explosions.
Other ob'ects and advantages of my improved muffler will be readily apparent by reference to' the following description taken in connection with the accompanying drawings, and it will be understood that I may make any modifications in the specific structure shown and described within the scope of my claims without departing from or exceeding the spirit of my invention.
Figure 1 represents'a view of "my complete muflier. Fig. 2 represents a view thereof with the inclosing casing shown in section. Fig. .3 represents a' longitudinal sectional view of the entire mufller. Fig. 4 represents a cross sectional View thereof on the line 44 of Fig. 1, and Fig. 5 represents a sectional view on the line 55 of said figure.
In the drawings, the numeral 1 designates the main casing of my improved mufller, said casing having the flaring frontbell port-ion 2 and having at itsother end the tapering neck 3 terminating in the exhaust pipe 4.
Leading toward and projecting within the casing 1 is the exhaust pipe 5 which has Specification of Letters Patent.
Application filed August 29, 1911. Serial No. 646,576.
- Patented May28,1912.
mounted thereon a collar 6 bearing the radiating arms 7 which are secured to and serve to support the rear end of the pipe 8. Said pipe flares rearwardly and terminates in the bell portion 9 which extends outward and is secured to the interior of the casing 1. Said bell portion vandthe tapering end of the casing together 'inolose the mixing chamber 10 having extending thereacross the,
brace .11 bearing the conoid deflector 12 for aiding in breaking up the exhaust gases, a screen 13 being secured at the termination of the main portion of the casing and serving to further break up the exhaust gases,
and to, cause a thorough mixing of said gases with the air in the chamber 10'.
Radiating from the pipe 8 are the small forwardly inclined air receiving branch pipes 14, while'inclosing the pipe 8 and branches 14 is a branch or supplemental casing 15 having ports through which the pipes 14 communicate with the space inclosed by I the casingl. M
In the use of my muflier as the automobileequippedtherewith moves forward air will-be caught by the bell 2 of the casing 1 and continued movement of the machinewill cause said air to pass through the pipes 1 4 into'the flaring exhaust pipe'8. To fur- 8 I connect the ends of the pipes 8 and 15 by the partition or wall 16 which is so flared as to guide air into the pipe 8. The flaring of the pipe 8 allows the air and exhaust gases .to. mix without causing a back pressure in the'exhaust pipes while therush of air in at the rear end of-the pipe 8 and also in through the various pipes 14 eliminates all danger of back pressure, this gas increasing with the speed of the machine and consequently driving out the exhaust gases at approximately the sameproportional speed relative to the speed of operation of ther supplement'passage of air into the pipe.
mufiier which while but slightly retarding the outward flow of the exhaust gases and thus but little hampering the eflicieney of the engine will satisfactorily break up the body of said gases and mix the same with airbefore they are allowed to pass from the muffler and will thus satisfactorily muflie the engine, andeliminate the smell and smoke delivered from the exhaust.
I claim:
1. An automobile muflier comprising an outer casing having a flanged end, a pipe mounted in said casing and inclosed in a second casing, said casing and pipe being provided with perforations, branch pipes having their inner ends secured in theperforations of the pipe and their outer ends se-' cured in the perforations of the casing, said pipes being extended forwardly and in the direction of the usual travel of the automobile, and an exhaust pipe leading to and extended into the casing.
2. In combination with an exhaust pipe, of a casing having a flanged end. through which is extended a second'casing mounted in said casing, a pipe mounted in the second casing, branch pipes connecting the pipe and second casing, said pipes being inclined toward the flanged end of the casing, a mixing chamber into which the exhaust empties, a conoid deflector mounted in advance of the mixing chamber, whereby the exhaust gases are broken up before entering the mixing chamber.
In testimony whereof I affix my signature, in the presence of two witnesses.
