In operating the power rapid HIGH EFFICIENCY IN SANO BLASTING AND PAINTSPRAY WORK. The advantages of the sand blast fur many classes of workhave been accorded general recognition for quite a long period,but the adoption of such apparatus has not proceeded heretofore with the rapidity which might be looked for, largely 011account of the excessive cost of the machinery necessary to doeconomical and efficient work. The sand blast apparatus herein illustrated, which is a productof the Mott Sand Mfg. Co., of Chicago, 111., through the. THE NEW IXDIAN.\POLIS TURRET L.\THE. traverse none of the headstock gears or feed gears are used,so that neither the pilot wheel on the turret slide nor the handwheel on the tool post carriage turn or move in either directionwhen the rapid traverse is thrown in. This power rapid tra-verse mechanism is driven from the main driving shaft of themachine, and does not require separate countershaft or motor. The tool post is of the four-sided heavy turret type. It willcarry four tools at one time, and each is independently adjust-able for height. This tool post can be clamped in any desiredposition, or locked in any of eight different positions. It is otvery rigid construction and has a double acting clamping device,both inside and outside, so that broad faced tools can be usedto advantage. Both cross and lateral power feeds are provided,and it has a rapid traverse altogether independent which willoperate either way, whether the feeds are on or off
