Abstract
608,716. Drilling-machines. ALEXANDER, J. W. Feb. 28, 1946, No. 6227. [Class 83 (iii)] [Also in Group XXXV] Observing tools and work.-A drilling-machine comprises a pivoted arm, a support on which the arm is mounted, optical means on the arm for viewing location marks on the work-piece, a drill carried on the arm, and means for securing the arm to its support at either of two positions corresponding to the angular distance between the axes of the viewing means and the drill. The drill s and microscope r are carried on the arm f at equal radial distances from the pivot f<SP>1</SP> by which the arm is mounted on the vertically adjustable support e, and are indexed by a plunger 3 working in holes 5 similarly positioned on the arm. The drill spindle is belt-driven by an electric motor w (see Group XXXV) and is fed to the work by the hand lever 6 which operates a cam acting against a spring.
