MOTOR-DRIVEN MACHINE TOOLS. Applications to Special Machinery. Under this heading in our May issue a number of special ap-plications of motors to machine tools were presented, and theaccompanying five engravings show others of equal interest. Fig. 1 illustrates a motor-drive applied to a more highlyspecialized class of tool, this being the recently re-designed 50by 10-in. automatic gear-cutting machine, with automaticworm hobbing attachment, built by Gould & Eberhardt,Newark, N. J. The motor, which is a Lundell direct-current motor, is most conveniently mounted upon an extension of thebase at the rear out of the way, and drives direct throughgearing. The switch and starting box for operating it are con-veniently mounted upon a stand at the rear, so that the tool,while self-contained, is very compact. J a«lEJ 9 «Hl3™M*3&.
