The vertical spindle is driven by a lircmze wormwheel and hardened steel worm litted with roller thriKst bearingsrunning in oil. Spindle .speeds ranging from I6J-2 to 99 r. p. obtained by means of a gear box giving nine changes; thecross feed on the rail has twelve changes and a reversing fastpower traverse. The spindle is 3^ in. in diameter in the drivingsleeve and has a Xo. 6 Morse taper with a broad face key in theend for driving cutters. The spindle sleeve is adjustable liy meansof a hand controlled rack and pinion. Auxdiary bushings which rotate witli the shaft are earrie<l bythe spline shaft bushing.^ tn ])revent the escape of oil and pre- Tlu friction clutch shown in the engraving has been developedliy Ueandry & Company, Inc., 141 Milk street, Boston, Mass., incoimection with the aiJplication of individual motor drive to its. Single Pulley Driven Vertical Slabbing Machine serve the fixed bushings from undue wear through contact withspline or keyseats. The table has twelve feeds ranging from in. to 13 in. which are independent of the spindle speeds. In addition arapid traverse of 30 ft. per min. is provided in both speeds and feeds are obtained through gear boxes, the gearsbeing entirely encased in oil tight boxes. This machine is builtby the Newton Machine Tool \\orks. Inc., Twenty-third and \, Philadelpliia. Pa., and may be had with two, three or fourspindles if desired. Water Power in —In Switzerland water poweris conserved and utilized to such an extent that in some townsnot an ounce of coal is used. Power, light and heat are fur-nished by water power.—Pozccr.
