I06 vided with an automatic down-feed, tlie screw for which isprovided with a graduated collar reading to .001 in. The viseis of a special design in which the fixed jaw extends downto a scraped bearing on the table, thus providing an unusuallylarge footing. Ball bearings are used under the elevatingscrew for the rail, and also the length of the stroke is veryeasily changed while the machine is in motion. The 3(l-in. planer (tool No. 17) illustrated on page 103, aswell as the 54-in. planer (tool No. 15) shown on page 104, aremotor-driven planers built by the Pond Machine Tool Com-pany, the former driven by a 7% multiple-voltage, and thelatter by a constant-speed Crocke
