Abstract

382,954. Drilling-machines. MASON, W. H., 59, Kenwood Road, Stretford, Manchester. June 8, 1931, No. 16620. [Class 83 (iii).] Drills.-A drill for boring non-circular holes has a bit incorporating a cutter oscillating in a groove therein, the shape of hole cut being determined bv a cam removably carried in the frame of the drill. In one form, Fig. 1, the bit carries a pivoted cutter 5 the head of which has a recess in which engages the raised contour of a cam 7 removably mounted in the non-rotating extension 8 of the drill frame. A variable cam comprises a number of pointed slats 13, Fig. 2, pivoted on a circular frame 16 mounted on the drill frame. The slats are formed to the desired contour by a gauge and locked by a pad 14 and ring 15. In a modification the cutter slides in a recess in the bit and a spring keeps the head of the cutter in contact with the cam, which imparts an up-and-down oscillation to the cutter. As the cutter is thrust downward the cutting end is thrust outward by the bevelled lower end of the groove.
