Abstract

526,285. Exhaust-silencers. MOSS, E. W. (Ingersoll-Rand Co.) March 11, 1939, No. 7941. [Class 7 (ii)] In means for muffling the exhaust gases of percussive drills, a casing 20 surrounds the working cylinder 22 and is divided into compartmentt by partitions 39, 40. Exhaust gas from a port 28 escapes into a compartment 35 and by channels or passages 46 into a compartment 43, and from thence by passages 47 in a compartment 44 to the outlet ports 45. A flexible sheet 48, which may be of rubber, confronts the exhaust port and is agitated there by to prevent the formation of ice.
