THREE-SPINDLE DRILLING MACHINE. ON page 134 we illustrate a three-spindle drilling machine with traverse table made by the Niles Tool Works, of Hamilton, Ohio. The drill spindles are placed on a fixed rail, and are adjustable lengthwise. They may be brought to within 7$ inches from centre to centre. The spindles have 12 inches travel, and each has hand and power feed. A four-step cone of large diameter, and strongly baok-geared, transmits power to the spindles, and gives ample power for drilling three U- inch holes at the same time. A bed and table similar to the bed and table of a planer are used for supporting the work. The table is moved along the bed under the drills, adapting it to drilling a series of holes in heavy work, such as vault doors, &c. The drill was specially designed for use in safe works, building heavy vault work, and for such work it is a desirable tool, as it saves both labour and time.
