Abstract
1308485 Percussion tools GARDNERDENVER CO 20 Nov 1970 [18 May 1970] 55402/70 Heading B4C A percussion tool comprises a reciprocable hammer element 16, and force transmitting means, including a bit portion operable to transmit percussive blows from the element 16 to a load. The force transmitting means includes an elastic, e.g. alloy steel or titanium alloy, member 36 operable to deliver force pulses from the hammer element to the bit portion, and comprising a shank portion 50 having a stiffness selected in accordance with the effective stiffness of the load. The tool includes receiving means for receiving one end of the shank portion 50, which is removably insertable in the receiving means. The tool also includes retaining means for removably retaining the shank portion in the receiving means, and the shank portion includes means engageable with the retaining means. In one embodiment, the hammer element 16 is reciprocated by compressed air fed via a valve 22 to chambers 18, 20 alternately in a tool casing 12 and engages a surface 46 of the member 36. A motor means 24 drives a shaft 28 and a pinion 20 which engages gear means 32 on a chuck 26 rotatably mounted in the forward part 42 of the tool casing, The member 36 is mounted in the chuck to be movable axially but not rotatively relative thereto, and is is releasably retained in the tool casing by a retainer 44 which engages a shoulder 54 thereon. The member 36 has a passage 56 for cleaning fluid. At its lower end the member 36 may be threaded to engage the upper member 72 of a drill string carrying a bit at its lower end. Alternatively the member 36 is welded to a drill rod having a releasable bit at its lower end. The drill casing 12 may be slidably mounted on a support carried by an adjustable arm mounted on a tracked vehicle.
