Abstract
445,089. Percussive drills. AKTIEBOLAGET ATLAS DIESEL, Sickla, near Stockholm. Sept. 21,1935, No. 26226. Convention date, Oct. 26, 1934. [Class 124] The space 11 surrounding the anvil block 9 is constantly subjected to the pressure of the actuating fluid through the passage 13, to maintain the anvil block in contact with the steel. A non-return valve 17 prevents the entry of washing water into the valve space 5. A passage 15 connects the space 11 to the central conduit in the steel. Specification 390,637 is referred to.
