Abstract

558,413. Drilling-jigs. FAHMY, L. H. Dec. 15, 1942, No. 17789. [Class 83 (iii)] A drilling-jig comprises a base S having parallel grooves G along which are slidable blocks F carrying rods fitted with corner pieces E for locating the work piece J, the base being also provided with pillars P supporting a primary guide A fitted with one or more secondary guides B at right angles to the guide A. The guides may accommodate carriers C in which the drill bushes are mounted. Alternative positions X, Y, are provided for the supporting pillars. By rotating a cam shaft L, Fig. 2, the pillars may be raised against the pressure of springs T for the insertion of the work. The bushes for guiding the drill are interchangeable and are formed with knurled exterior surfaces and with cut-away parts E<SP>1</SP>, D', Fig. 5, so that they may be withdrawn upwardly by first turning the parts E<SP>1</SP> into register with the holding-down screws B<SP>1</SP>.
