MACHINE TOOL MOTOR APPLICATIONS It is frequently desirable to apply an electric motor to a ma-chine tool which is designed for, and has been operated, by a beltdrive. For example: it is sometimes found necessary to operatethe for a whole group of machines a large proportion ofthe time in order to drive a single tool in the group, in whichcase it might be advisable to provide the tool with an individualdrive. Again, the constant improvements being made in the vari-. Motor Applied to a Belt Driven Lathe. ous shops often make it necessary or advisable to so locate amachine as to make it inconvenient, or impossible, to drive itfrom shafting. For use in such cases, the Burke Electric Company, Erie, Pa.^ JlXE. I51J AMERICAN ENGINEER. 323 is fiirnisliing a framework and motor support wliicli permits thedirect application of a motor to the tools, allowing them to beoperated in the same manner as if they were belted directly tothe coimtershaft. If a variable speed motor can be applied, thisarrangement also permits a decided increase in the range of speedchanges on the tool. In the accompanying illustrations arc shown applications madeby this company to a large lathe and to a shaper. It will be seenthat the cone pulleys are retained. The motors are so locatedas to take up very little, if any. extra room and drive throughbelts to the pulleys on the countershaft, which gives the necessary aprons for 24 in. high duty lathes recpiired 12
