Abstract

607,571. Drilling. QUICKTHO (1928), Ltd., and QUICK, W. Feb. 8, 1946, Nos. 4030 and 19396. [Class 83 (iii)] Jigs.-A pillar drilling - machine attachment for locating the bit is provided with a spring-pressed sleeve 6, Fig. 2, surrounding the bit 4, in which is fitted a detachable bush 8 adapted to locate the tool over a jig-bushing or work-piece or in an aperture. The main casing 1 is attached to a fixed part of the machine and carries the sleeve 6 in an extension 5 so that on contacting the work the spring 10 is compressed and the drill enters the work. The sleeve may slide on the outside of the main casing. Figs. 6 and 7 show modified forms of bushing, 36, 40. Removing cuttings.-Holes 15 are provided for the escape of swarf and for observation.
