It is also, however, sometimesapplied, to a vertical machine similar to a vertical boring-machine with a chuck rotating in ahorizontal plane, and the vertical sliding head carrying a turret for holding a variety of a machine is the Brown & Sharpe vertical chucking-machine shown in Fig. 7. Thedilferent tools in the turret-head are easily brought into operation, and. from their perpen-dicular position, allow, the chi[)s to fall through the center of the spindle of the revolvingtable to the floor, and thus avoid danger of trouble from the clogging of reamers, etc. The.
