Abstract

222,699. Duffill, J. Nov. 15, 1923. Exhaust-silencers.-A silencer comprises an expansion chamber c provided internally with a baffle element made of wires disposed radially around an axial stem b, preferably in the form of a helical brush-like fin or web a. The baffle may be made by laying a number of wires across a strip of metal, securing them temporarily by cement, and twisting the strip. The rod and baffle are secured to bridges d<1>, e<1> in the end members d, e.
