Abstract

477,245. Exhaust, and like silencers. KAUP, K., and LUCK, J. March 25, 1937, No. 8811. Convention date, July 29, 1936. [Class 7 (ii)] The exhaust conduit is connected to a series of tubes each formed with one or more spherical enlargements arranged one after the other without hindering the free exit of the gases. The Figure shows the exhaust pipe 1 leading to an expansion chamber 2, to which are connected a number of tubes 3 formed with enlargements 4. The tubes may lead directly to the atmosphere, and may be spread fanwise as shown; or they may be arranged in a casing so that the several streams of gas reunite in the end of the casing before escaping through a flared exit. The tubes may lead from the several exhaust valves of an engine.
