Description
MUFFLER Filed June 8, 1926 2 Sheets-Sheet 2 IN VEN TOR BY HMMMM 4 TTORNEY Patentetl Dec. 7 10, 1929 UNITED STATES PATENT OFFICE HERBERT B. POWELL, OF UTIGA, NEW YORK Application'flled lane 8 1926. Serial No. 114,524.
7 My invention relates to a muffler andI declare the following to be a full, clear, conclse and exact description thereof sufiicient enable anyone skilled in the art to which 1t appertains to make and use the same, referenee being had to the accompanying drawings in ,which like reference characters refer to like parts throughout the specification. The object of the invention is to provide a mufiler of' simple construction and adapted to effectively silence the noise incident to the discharge of the exhaust gases of an internal combustion engine. v
The muffler is built in sections, of the dumbbell type, which sections are connected by tubes that diminish in size progressively as the gases of explosion progress towards theatmosphere. Each of the sections is made up of cups that can be replaced easily in the event of the destruction of one or more of the same. Furthermore, the muflier-is equipped with pipes leading to a heater located within the automobile, whereby to heat said interior. There is a valve also for shutting off the admission of the exhaust to the heater and means for controlling the actuation of said valve.
The object will be understood by referring to the drawings in which:
Fig. 1 is the elevational view of the mufiler showlng parts broken away.
Fig. 2 is a transverse section taken on the line 2-2 of Fig. 1.
Fig. 3 is a detail enlarged view of used.
Fig. 4 is a central vertical section of the mufiler showing parts broken away other parts in full lines and made on a reduced scale.
F ig. 5 is a. fragmentary view showing a central vertical section of the remaining .part omitted from Fig. 4 and made on the same scale.
Fig. 6 is'a detail perspective view of one of the cups employed, showing the same in inverted po sition and drawn to the same'scale as Figs. 4 and 5.
Fig. 7 is a detail perspective view of another cup employed, showing the'same in in- Figs. 4 and 5.
a pivot verted position and drawn to the same scale as Referring more particularly to the drawings, the mufller ismade up of two or more sections, as 1, 2 and 3, which are connected by the tubes 4 and 5 arranged to diminish in size, as the gases progress towards the atmosphere' The connecting tubes 4 and 5 give the mufiler more orless the appearance of a dumb-belhand diminishing in size allow for the greatest expansion as the gases enter the mufller. and a gradual contraction thereof as they progress towards the atmosphere. Each of the sections is built up of detachable cupslO that are made to interfit by flaring out the upper peripheral edge at 11, whereby to form a shoulder against which the bottom of thepreceding cup 10 fits or nests. Moreover, the several cups 10 of each section, as 1, 2 and 3 are provided with end closing members 15 and 16 relative to section 1; 17 and 18 relative to section 2; and 19 and 20 relative to section 3. Inlet pipe 21 is connectedto closing member 15 by splnningor otherwise secured-the end, as at .22, thereto. Likewise, the last cup 10 of section 1 isformed with the circular wall 23 fixed in an air-might manner to closure member 16, which has an aperturethrough which projects the end-26 of tube 4, said end 26 being spun thereto. The opposite end of tube 4 is riveted in like manner to the closure member 17- fixed in an air tight manner to the circular wall 30, which forms the first cup of second section 2.
sure to atmosphere.
J In order to further break up the gases in their assage through the muflier apertures of di erent forms have been made in each f the cups 10 ofeach section we In section 1 an expansion chamber is formed by making largecentral apertures 40 in the bottoms 41 of each of the first three cups 10. The fourth cup 10 is equipped with small apertures 42 made by punching or stamping the same through the bottom 41., thereby forming flanges 43 surrounding said apertures 42 to disseminate the heat and, thence aid in cooling the muffler.
The apertures 42 will tend to break up and segregate the on-rushing gases which will be contracted then by passlng through the connecting tube 4 which is smaller in diameter than the cups 10. From tube 4 the gases will pass to the second section 2 which is made up alsoof five cups 10, the first oil which has a large central aperture for the unimpeded progress of the gases, whereas, the next three cups 10 are equipped with apertures .42 formed with flanges 43 for disseminating the gases.
The gases will pass from section 2 to section 3' by way of tube 5 which is spun at end 44 to closing member 18 of section 2 and at its opposite end 45 to closing member 19 of section 3. Cups 10 in section 3 are similar to the cups 10 in section 2 and arranged in the same order with the first one having a large central aperture 40 in its bottom 41 and the next three with small flanged apertures 42. The gases will pass from section 3 to atmosphere through tube 35. 1
Tube 35 is spun at one end, as at 36, to the end closure member 20 of the third section 3.
- It is still smaller in diameter than connecting tube 5, and, as above stated, tube 5 is smaller in diameter than tube 4, whereby there is efi'ected a progressive diminishing,
ratio relative to the sizes of the diameters of said tubes4, 5 and 35. I
The several cups and sections of the mufiler are held together by stay rods 55,55 that are projected through apertures made in said cups and end members and terminate at each section. The ends of said stay rods are threaded for the mounting of nuts 56, 56 that are tightened thereon to bind the parts together. I p
The means for diverting the gases from a direct passage through the muflier embodies the pipe or tube 60 which has one end spun at 61 to the edge of the aperture formed in closing member 16 of section 1 and its opposite end spun at 62 to the edge of the aperture formed in closing member 17 of second section 2. Pipe 60 is doubled on itself. in parallel planes to form a heater 63; which part will be disposed within the interior of the automobile, not here shown. The means for controlling the passage of the gases of explosion to the heater 63 embodies a rock valve 65 that is fulcrumed and mounted on the square end 66 of a pivot 67 with which said valve 65 turns.
In operation the exhaust gases enter the muliler through inlet pipe 2-1 and are allowed to expand in a chamber 60 formed by the first three cups 10. They are contracted, however, as they pass through the apertures 42 of the fourth cup and still further contractedon passing through connecting tube 4. On entering the second section 2 the gases are allowed to again expand through a smaller expansion chamber 61 formed by the first two cups 10 andthen contracted on passing through the next three cups 10 and still further on passing through connecting tube 5. On entering the third section, the gases are allowed to expand only While passing through the first two cups 10 and.
-ment that aids materially in breaking upand disseminating the gases Without unduly impeding their progress with the resultant back pressure on the engine.
A cord 80 will beattached to the'lever 70 and runs to the interior of the automobile. In the event that it is desired to have the exhaust gases enter heater 63, the operator I will actuate the same to move valve 65 from full to dotte i posit on or n t event that he wishes to divert the gases from Patent is as follows 1. In a muifler for exhaust gases, a plurality of sections, tubes connecting said sections and said tubes being disposed in prolongation of each other and reduced progressively in size, whereby to aid in breaking up the exhaust gases.
2. In a mullier for exhaust gases, a'plura l ity of sections, each of said sections comprising a series of cups, apertures formed in said cups for causing the exhaust gases to take a tortuous course, tubes disposed in prolongation of each other and gradually diminishing in size for connecting said sections, whereby to aid injbreaking up the exhaust gases.
3. In a muflier for exhaust gases, a plurality of groups of cups, certain of said cups having apertures with conical shaped flanges, whereby: to aid in disseminating the heat of the exhaust gases, and tubes disposedin prolongation of each other and progressively diminishing in size connecting said groups of cups, whereby to aid in causing said gases totake a tortuous course.
