Abstract

292,323. Electro-Mechanical Brake Co., Ltd., and Smith, S. May 14, 1927. Exhaust-silencers.-A casing a, tapered at its ends and connected to the engine exhaust pipe at b, encloses a number of coaxial tubes d, e, f The tubes are of different lengths, the central tube being the shortest, and the annular spaces be tween the tubes as well as the space between the outer tube and the casing are occupied by helical metal strips g forming helical passages of different lengths. The helical strips may be of different pitch in the different spaces. Specification 208,270 is referred to.
