Abstract

940,945. Drilling and boring. MAGCO Ltd. May 21, 1962 [March 14, 1961], No. 9199/61. Headings B3B and B3C. A drilling device comprises a drill head b, incorporating a drill and electric driving motor, which are slidably mounted on a vertical post a<SP>1</SP>. Vertical adjustment of the drill head is effected by a manually rotatable screw c engaging a nut d in the drill head. The nut d is in two parts each provided with a trunnion d<SP>2</SP> which co-operate with a member d<SP>3</SP> of a lever d<SP>1</SP>. The movement of the lever engages or disengages the nut from the screw to permit rapid displacement upwards or downwards of the drill head. The base a of the vertical post a<SP>1</SP> may be magnetic to facilitate the positioning and retaining of the device in relation to the work.
