Abstract

1432504 Impelling tools INST GORNOGO DELA SIBIRSKOG OTDELENIA AKAD NAUK SSSR 6 May 1974 [30 Oct 1973] 19901/74 Heading B4C A portable pneumatic tool comprises a casing 1 having a housing 5 mounted for movement therein and a main piston 6 which is movable within the housing, chambers within the housing on either side of the piston which can be supplied with compressed air alternately to reciprocate the housing and piston relative to each other and to the easing, an additional piston 14 reciprocable relative to the casing and drive means for reciprocating the additional piston relative to the casing and in the opposite phase to the movement of the housing the volume of the space defined within the casing being maintained substantially constant. The hammer piston 6 is of composite construction and comprises a rod 7 and shank 36 locked together by a pin 37. The hammer piston is also provided with an air distribution valve for connection to a compressed air source.
