Abstract
20,608. Flottmann, H. Sept. 30. Rock drills.-In a rock drill which can be shifted longitudinally for facilitating the exchange of drills independently of the ordinary feed, without moving the machine out of alinement with the hole, the part of the machine that is movable during working is made of two longitudinally-adjustable parts. In the example shown the drill 5 and a lower part 6 are fed on a bed 1 by means of a toothed wheel 4 and a rack 2. The drill 5 is formed with flanges 9 which embrace a flange 7 on the part 6 so that the parts 5, 6 can slide on each other. The flange 7 is formed with recesses 8 and the flanges 9 are formed with a corresponding recess through which and any one of the recesses 8 a wedge 10 may be inserted to lock the two parts in their adjusted position. The wedge 10 may be so formed that it can be moved free of the recesses 8 without being completely withdrawn. The flange 7 may be on the part 5 and the flanges 9 on the part 6, and the two parts may be otherwise secured, for instance by a set-screw.
