Abstract

The invention relates to an extraction device used for extracting pneumatically actuated impact tools and the like from boreholes. The device includes a carrier member (1), a reciprocable hammer (2), and a sleeve (13). The carrier 1 is adapted to be connected to a drill rod section. Reciprocation of the hammer relative to the carrier is used to effect extraction. Fluid passages (6), (16) are provided for conveying fluid under pressure through the device in order to cause the hammer to reciprocate and in so doing to strike a striking surface (8). <IMAGE>
