Abstract

684,406. Hand drills. NALDER, F. J. H. Nov. 15, 1950 [Nov. 15, 1949], No. 29238/49. Class 83 (iii). A hand-held drill has two sighting members 1, 2 attached to or formed integrally with its stationary body 7 equidistantly from the axis of the body on a line parallel with said axis. Apertures 3 in the members 1, 2 may be viewed through a prism or a mirror 10 mounted pivotally on the body and the drill adjusted so that the apertures are aligned with the axis of a hole 14<SP>1</SP> in a target 12 placed on the work-piece 9 at a distance from the point to be drilled. The sighting members, which may be carried by a rod or bracket pivoted on the body 7, or may be pivoted on the rod or bracket, may comprise the ends of a tube, or lenses mounted in the tube, or cross-wires in a telescopic member. The target 12 may have radial holes therein to admit light and be of conical form with sighting rings on the outer surface thereof; it may also be formed as part of a V-clamp to grip circular work. Alternatively, it may be pivoted in a yoke 27, 28, Fig. 4, to be adjusted angularly against a scale 30 and aligned with a mark on the work viewed through a slot in the base 29. The targets, which need not have a sighting hole, may have a magnetic base for gripping the work and, when drilling perpendicularly to the work, may be replaced by a mirror on the work.
