BAFFLE TYPE MUFFLER WITH PLURAL TUBULAR PASSAGES Filed Jan. 26, 1948 Patented Feb. 28, 1950 UNITED STATES PATENT OFFICE BAFFLE TYPE MUFLFLER WITH PLURAL TUBULAR PASSAGES Application January 23, 1948, Serial No. 4,358
3 Claims. l
This invention relates to baille type muiller with plural tubular passages and more particularly to mufllers such as intended for internal cornbustion engines.
An object of the invention is to provide a mufer which is highly efficient in its operation, inexpensive to produce, and which may be used at the end of an exhaust pipe.
A further object of the invention is to provide such a muler which is compact and attractive in appearance.
Further objects and advantages of this invention will be more clearly understood from the following description and from the accompanying drawings, in which- Fig. l is an end View of a muiiler embodying our invention.
Fig. 2 is a side view thereof.
Fig. 3 is a side view in central vertical section.
In the embodiment shown, our invention embodies a ymuilier having a casing or outer shell 5 with an end plate 6 at one end thereof that is provided with an opening which communicates with the interior of a tubular portion 'I that receives the end of an exhaust pipe 8 and has a plurality of slits 9 permitting the said tubular portion to be secured to said exhaust pipe by means of a suitable clamp I il. At the interior of said casing there is provided a screen II at one end which extends across the opening in the plate 6 and a screen I2 at the opposite end which is supported by the ends of a plurality of tubular sections I3, I4 and I5.
The section i3 is preferably smaller than the sections I 4-I5 in order to provide a preferred formation whereby the open end of the muiiler casing is iattened, as illustrated in Fig. 1, and the said tubes are joined together and secured to the casing by spot Welding, or the like, as indicated at I6, to retain the said tubes in position wherein they are in alignment with the end of the casing 5 and support the screen I2.
The inside of the casing between the screens Il and l2 is filled with a suitable material i1, such as a Wool made of glass iibers or the like, to provide a muiiling eiiect for the exhaust gases passing through said muiiler. This wool has been found highly eicient in reducing the noises of combustion with a minimum of back pressure.
' In fact, said wool material has been found to be far more effective and with less back pressure than the conventional form of baille plates usually provided in muiers.
We claim:
1. A muiiler of the character described comprising a casing, an end plate having an opening therein and a tubular portion, a perforate sheet of material contained within said casing and positioned against said end plate across said opening, plurality of tubular members within and adjacent the opposite end of said casing and extending longitudinally thereof, a perforate sheet or" material within. said casing and against the ends of said tubular members, and a fibrous mass :filling said casing between said perforate sheets.
2. A muler of the character described comprising a casing, an end plate having a tubular member extending therefrom and communicating with an openin in said end plate, a disk of wire mesh material contained within said casing and resting against the inner wall of said end plate and extending across the opening therein, a plurality of tubular members in parallel relationship with each other and the axis of said casing contained within the end portion of said casing and secured thereto, a sheet of wire mesh within said casing abutting the inner ends of said tubular portions, and a mass of metallic wool :lilling the casing between said sheets of wire mesh to muiiie sounds from exhaust gases passing through said muffler.
3. A muffler of the character described comprising a tubular casing, an end plate closing one end of said casing and having an axial opening therein with a surrounding tubular portion extending therefrom, a plurality of tubular members extending inwardly from the opposite end of said casing parallel to the axis oi said casing, a screen member contained within the casing and abutting the said inner ends of the tubular members, and a similar screen abutting the inner wall of the end plate and extending across the opening therein, the said tubular members being secured together and to said casing to prevent displacement thereof, and a mass of fibers filling the space between the said wire mesh members to munie the sound of exhaust gases passing through said casing.
