Abstract

718,756. Percussive drills. TAMPEREEN PELLAVA-JA RAUTA-TEOLLISUUS OSAKE-YHTIO. Oct. 21, 1952, No. 26411/52. Class 124. [Also in Group XXII] A compressed air feed cylinder for feeding a rock drill is secured by anchorage to the material to be drilled. As shown, a feed cylinder 2 attached to a rock drill 1 has a fork 6 into which is placed a link of a chain, the other end of which is fixed to an angle-anchor 5 disposed in a drill hole in the face 3 being drilled. The chain may be replaced by any flexible, adjustable means, or by telescoping rods. The anchor may have a transverse spring to prevent its falling out of an overhead hole. When drilling an horizontal hole the anchor should be placed above the drill so that the latter may be in part supported thereby.
