Abstract
Apparatus for manipulating a tool which is particularly suited for use in drilling and inserting bolts into thin seams of mine workings. The apparatus (100) comprises a reaction support member (4) to support the tool, a chuck (1) for holding the tool, mounting member (12) in which the chuck (1) is mounted, and a lever linkage (13) connected between the mounting member (12) and the support member (4). The lever linkage (13) comprises parallel chuck orienting members (5, 10) connecting the mounting member to a control member (9), said control member being adapted to manipulate the chuck orienting members and to control the orientation of the chuck. The lever linkage further comprises first and second links (14, 15) each having first and second ends. The links are pivotally attached to each other at the first ends thereof. The first link is pivotally attached at the second end thereof to the mounting member and the second link is pivotally attached at the second end thereof to the support member. The apparatus also comprises a moving device arranged to supply a force to the first ends of the links to cause movement of the mounting means.
