Abstract
543,213. Hand drills. CHESSHIRE, C. G. S. Jan. 16, 1941, No. 611. [Class 83 (iii)] An archimedian hand drill for countersinking, removing burrs, or drilling small holes in aluminium or other soft metal has the cutter carried by a spindle 6 slidable in a sleeve 3 but driven therefrom by slots 7 and pins 8. The sleeve is secured to the screw 4. Feed is limited by a spring 10 confined between the end of the sleeve 3 and a collar 9 on the spindle 6. Compression of the spring is limited by contact of the end 13a, of the sleeve, with the work. The parts are enclosed by a sleeve 13 revolubly secured relatively to the sleeve 3 by key bits 12 engaging an annular groove in the sleeve 3 and retained in place by a ferrule 14. The other end of the screw is secured to a piston 22 sliding in a handle sleeve 16 as opposed by a strong spring 23. A ferrule 17 is secured to the sleeve at 18 and has bolted to it the nut 19.
