Abstract
20,611. Erlebacher, J. Sept. 30. Boring and drilling. - Curved holes are bored in metal, wood, leather, or the like by means of a drill or boring-bit mounted on a curved guide-tube. The drill is driven by a flexible shaft, operated by hand or otherwise. Fig. 3 shows one arrangement in which the guide-tube consists of two quadrants connected at 15. The tubes are slotted to permit the passage of the shaft 14, or may be a framework merely. The front quadrant may be arranged to slide in the rear one ; it is then pushed out during the drilling of the first part of the hole.
