Abstract

1,025,744. Silencers for gaseous flow. CONSOLIDATED MINING & SMELTING CO. OF CANADA Ltd. Sept. 23, 1963 [Sept. 28, 1962], No. 37296/63. Heading FIB. A sound suppressing device for a compressed air percussive tool comprises an elastic sleeve 22 surrounding the body 11 of the tool in the vicinity of the exhaust ports 14 and engaging at its ends on collars 20, 21, formed or mounted on the body, the air escaping between at least one of the collars and the end of the sleeve. The handle 13 of the tool is mounted on a boss 18 extending through a slot in the sleeve 22, which sleeve may be formed to engage the collar 21 at the chuck end of the tool more tightly than the other collar 20 so as to force all the air to escape past the collar 20. Slots 30, 30a, Fig. 4 (not shown) may be provided in collar 20 to reduce the extension of the sleeve at the collar by the escaping air, alternatively a small extension tube 31, Fig. 5 (not shown), may be provided to allow a portion of the air to by-pass the collar.
