Abstract
1,031,009. Percussive drills. ATLAS COPCO A.B. April 28, 1965 [May 4, 1964], No. 17851/65. Heading B4C. A drill steel centralizer comprises a support 10 having a slot 23 and a keep member 19 also having a slot and pivotal between a first position in which both slots are aligned in order to receive a drill steel 15 and a second position, wherein the open ends of the slots are opposed so as to retain the drill steel. The support 10 is mounted on a bracket 11 secured, by means of plates 12, to a feed shell 13 along which a percussive drill 14 is movable. The keep member 19 is provided with a handle 20 in order to facilitate rotation between the two positions.
