Application September 24, 1951,
Serial No. 247,964
1 Claim. (01. 18170) struction, strong, durable, highly efficient and reliable in use, compact and which may be manufeatured at low cost.
All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the tion, taken in connection with the accompanying drawing, wherein like characters of reference designate corresponding parts throughout the several views, and wherein:
Figure 1 is a view in longitudinal section through a portion of a muffler constructed in accordance with the present invention;
Figure 2 is a view in transverse section through the device; and
Figure 3 is a plan view of the blank from which the baffles are formed.
Referring now to the drawing in detail, it will be seen that the embodiment of the invention Which has been illustrated comprises a tube 5 of suitable metal. The tube 5 may be of any desired length and said tube is preferably of a diameter corresponding to the usual exhaust and tail pipes which are to be connected to its ends.
Fixed in the tube 5 at longitudinally and circumferentially spaced points is a plurality of metallic bafiies 6. The baifles 6, which are formed from a single sheet of metal, are substantially in the form of segmental cones comprising reversely bent longitudinal marginal portions constituting attaching flanges which are firmly secured to the tube 5 in any suitable manner.
As illustrated to advantage in Figure 2 of the drawing, the baflles 6 have formed therein a multiplicity of openings or perforations 8. The arcuate rear ends of the bafiles 6 define moisture passages 9.
It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefly, the exhaust gases from the usual exhaust pipe of the engine enter the following specificatube 5 and are mufiled by the baffles 6 around and through which said gases pass.
of the exhaust gases may flow straight through the mufller. Any moisture or fluid Which may enter the muffler will be carried therethrough by the exhaust gases, this elimination being facilitated by the passages 9, thereby preventing the formation of rust and materially prolonging the life of the muffler.
It is believed that the many advantages of a invention as claimed. liaving described the invention, what is claimed as new is:
A rnufiler comprising a tube having an inlet at RICHARD W. COOPER.
