SPECIFICATION forming part of Letters Patent No. 784,833, dated March 14, 1905.
Application filed December 6, 1904. Serial No. 235,708.
loal/ 10/1/0171.- H 'n'my concern:
Be it known that I, ALANSON P. BRUSH, a citizen of the United States, residing at De troit, county of Wayne, State of Michigan,
have invented a certain new and useful Iminafter described and claimed, and illustrated in the accompanyingdrawings, in which Figure 1 is a view in section, showing parts in plan or elevation, as the case may be. Fig. 2 is a View of parts in, section, showing a modification. Fig. 3 is a view in cross-section on the line 8 3, Fig. 2.
In the drawings, (0 represents an exhaust pipe or channel to carry the products of combustion from the combustion-chamber of the cylinder of an internal-combustion engine. The extremity of the exhaust-pipe is led into a coincident pipe or channel, (indicated at 6.) Both the pipes a and Z) communicate with a muffler drum or chamber (indicated at c) of any suitable proportions. Leading from the pipe or channel 1) toward its base is a conductor (Z. This conductor (II have shown comn'mnicating with the interior of a pipe or channel from which' leads a coincident pipe f. Both the pipes r and f comn'iunicate with a second or additional muflier-drum a. To the opposite end of the discharge -pipe f is connected a discharge-mp0 71 (shown in the drawings submitted herewith,) communicating with theatmosphere at its outer end. The chambers 0 may be of any suitable construction. As shown, they are each formed with heads 17 at opposite extremities and a suitable cylinder Z', secured to said heads, the heads being shown connecting by connecting-rods but I do not limit myself to any specific construction of said chambers.
I. have shown herewith two chambers, the
one communicating in to the other through the conductor (7, and l have shown means whereby the second drum or chamber, as the drum g, discharges to the atmosphere. I do not, however, limit myself to the employment of two mufflerchambers, inasmuch as for some purposes a single chamber with its connected parts may be found sufiicient, and in other cases it will readilybe seen that the discharge pipe 71 might lead into an additional mufiierdrum constructed and arranged with parts corresponding to the drum 2. My invention therefore contemplates as coming within its scope the employment of either a single muffler drum or chamber with its connecting parts or any desired multiple of drums connected up in a manner similar to that illustrated in the accompanying drawings. For many purposes, however, the en'iployment of two muflier-drums, the one discharging into the other, will be found sufficient. The case of each of the drums with the corresponding heads are made tight, and it will be perceived that there are no small orifices employed to be stopped up .with soot. it will also be perceived when the products of combustion are discharged from the exhaust-pipe a. into the drum 0 there is no appreciable back pressure. The gases discharged into the mu filer-drum, it will readily be perceived, do not pass through the muflier-d rum at all, but simply enter one end thereof, the gases being turned back to find their exit through the coincident opening within the channel (shown in Fig. 1,) located about theinnereml of the exhaust-pipe. The gases passing into the muffler-drum retard in some degree the discharge. of the gases from the muffler, the elasticity of the gases in the drum taking the shock of the entering discharge, the gas in the drum being slightly compressed by the momentum of the incoming gases. it is obvious that the gas will leave the first drum in a long impulse instead of in short and sharp impulses, like the impulses of. the incoming charge or exhaust. The gases will flow out thus from the first drum at a slow rate of speed and in prolonged impulses. It
will be understood that the exhaust passes through the pipe 1/ in a series of short and sudden impulses, and because of the retarding effect already described the outward flow from the drum will be, as above stated, in longer impulses. The exhaust-gases passing through the connecting-pipe (Z enter the next drum, where practically the same process is repeated as already described as taking place in the first drum, the impulses after leaving the first drum being longer and slower than the entering impulses of the exhaust. The gases will not liow into the second drum so but that they can readily be handled through pipes of smaller area. Consequently the coincident openings into and from the second drum may be reduced. The process may thus be carried on until the flow from the drums will become a steady and continuous flow withoutany trace of impulses whatever. The last discharge would need to be one of sui'licient area to handle the quantity of gas to flow therefrom in a steady continuous flow or a 'tlowthat was perfectly uniform. in practice it is found that two chambers of sufficient capacity will give a close approximation to a continuous flow of the exhaust to the atmosphere. if it was desired, .the openings into and from the chambers might be reduced, so as to increase the velocity of the gas, and thereby increase the compression in the correspondingchamber. While this would begin to cause a back pressure, still wemight use but a single chamber with very fair results. Because the inlets and outlets are practically coincident the gases do not materially change in the drumv'. 0., in use the drums will each become gradually filled with the exhaustgases and if a motor fail to explode or the electric current should be cut off the motor would force a few charges of explosive mixture into the muffling system; but the charges would not pass through the drums and would not take the place of thenon-explosive gases in the drums, but the charge would go out of the one drum and into and out of the other to the atmosphere in a manner already set forth.
In Fig. l the pipes a 7) and f are shown concentric, and the pipes may be so arranged that is, 'n'actically concentric, it be ing unnecessary that they should be thus arranged with exactness.
in Figs. 2 and 3 the pipes are coincident at their extremities within the adjacent end of the corresponding drum; but, indicated more particularly in Fig. 3, the said pipes or channels may be elongated at their inner ends. in Fig. 1 the pipes 7) w are arranged about the pipes u f, respectively.
In Figs. 2 and 3 the openings of the pipes are arranged side by side; but in either way the openings of said pipes are coincident. It
will also be obvious that the pipes be, through which the muiiier-chambers discharge, are longer than the corresponding pipes of, the pipes 7) thus each forming practically, on account of their extension beyond the extremities of the pipes f, a single inlet and outlet opening. It will be evident that a muffler so constructed is ofsuperior elliciency and utility, inasmuch as each of the mul'llers is without back pressure and the mechanism is without small apertures or complications of construction of any kind, and inasmuch, also, as with this construction there cannot occur explosions of unburned charges within the nndller-chambers, with the attendant unpleasantness and danger of destruction.
It will be obvious that owing to the arrangement of the coincident openings of the inllow and outflow discharges a siphoning el'l'ect results, whereby the outllow of gas is retarded.
\Vhat I claim as my invention is 1. Amulllercomprisingmultiple chambers, an exl'laust-pipe leadinginto one end of one o l the chambers, an exlnmst-pipc leading from the same end of said chamber into one end of a second chamber, and an exhaust-pipe leading from the same end of the second chamber as set forth.
2. A mul'i'ler comprising multiple chambers each provided at one end thereof with an outflow-channel communicating therewith, a pipe connectingsaid channels, an exhaust-pi pe leading into oneof said channels, and an exhaustpipe leading from the other of said channels.
A mui'ller comprising a mulller-chamber having inlet and outlet passages coincident the one with the other, the outlet-passage projecting within the chamber beyond the inlet-passage.
t. A mui'ller comprising a mufller-chamber having inlet and outlet passages coincident the one with the other, the outlet-passage leading into the chamber beyond the opening of the inlet-passage whereby the outilow of the gases will be retarded by the inllow.
5. A muflier comprising a llllllllOF-Clltll'll)Ol' having inlet and outlet passages coincident'the one with the other, said passages arranged to form a single opening at the extremity of the outletpassage within said chamber.
('3. A mulller comprisi ng plural communicating mu filer-chain])ers coimected in series substantially as set forth, an exhaust-cliannel leading into one end of one of said chambers, and an exhaust-charmel leading from the corresponding end of the other of said chambers.
'7. Amulllercomprisingpluralcmnmunicating muflier-chambers, each of said chambers provided with coincident inletand outlet openings, said openings arranged so that the inflow ofgas through the inlet-channel will retard the outflow of gas through the outlet-channel.
In testimony whereof I have signed this specification in the presence of two subcribing witnesses.
