Abstract

1410140 Percussive tools MACO-MEUDON 5 Dec 1973 [5 Dec 1972] 56368/73 Heading B4C A percussive or rotary percussive tool comprises a two part body, the internal part 4 for containing the means for operating the tool being surrounded by an external part carrying a handle 6 and maintained in spaced-apart relationship therewith by elastic suspension means 16. The tool may be prevented from falling to the ground by a displaceable member 7. Soundproofing materials may be provided in the interior of the external part. Sound-proofing of the tool bit 3 may be provided by a skirt (8) which depends from the external part 5 in the form of a bellows, a series of strips or a helical spring, Figs. 2, 3 and 4 (not shown). Exhaust gases from the internal part 4 may follow a winding path (10a, 10b or 10c) Figs. 5, 6 and 7 (not shown). Fluid supply to the internal part may be through a flexible pipe (13) and a telescopic tube 15a, a hollow piston and cylinder (15b) or a bellows (15c) Figs. 9, 10 and 11 (not shown).
