Knight's American mechanical dictionary : a description of tools, instruments, machines, processes and engineering, history of inventions, general technological vocabulary ; and digest of mechanical appliances in science and the arts . Horizontal that a monitor turret can be turned in it work-table, instead of traveling in .slides, iscircular, and revolves like a face-plate on a verticalaxis. The tools are held in heads on a cross-slide,which is fitted to two uprights resting on cheek-jiieces bolted to the main casting or foundation-piece. On the under side of the revolving table is a bevel-gear driven by a pinion, which may be backed outof gear by means of a hand-wheel on a thread on thehorizontal shaft. Thehubof thispinion, beingsliglitlylarger in diameter than the pinion itself, as ajournal, by means of which the pinion is caused to re-volve with great steadiness, and when out of gear thepinion is within the pillow-block. This is requiredwhen a quick motion is given to the table by means ofa pair of miter-gears, one of which is attached to thelower end of the table-bearing. One of the heads onthe cross-slide is fitted for drilling, the spindle being4i inches diameter, with a travel of 18 inches, inde-j)en
