ABSTRACT:
A muffler mounting (26) for a muffler (21) which is connected to an internal combustion engine (11) by a rigid exhaust pipe (16). Previous mountings for such mufflers have either been of the rigid type, which subjects the muffler to undesired stresses resulting from shock, vibration or thermal expansion, or have utilized flexible rubber belting hangers which deteriorate rapidly when subjected to high temperatures. The present invention provides a relatively thin, flexible, generally-vertical metal hanger (52) comprised of a plurality of thin, stainless steel, strips (53) overlaid on one another, to flexibly connect and support the muffler (21) to the engine (11) or frame (12). The present invention is particularly useful in vehicles wherein the engine (11) is resiliently mounted on the frame (12) and wherein the muffler mounting (26) is subject to high temperatures, corrosion, and oxidation.
