In the preceding article of this series were described twoadmirable variable-speed positive-drive mechanisms which areapplied to the feeds of lathes. In this issue a mechanism ofsimilar character, which has been applied to the Cincinnatimilling machine, will be considered, ihis device belongs tothe same general classification of positive-drive mechanismswith the speed range varying through a definite number ofsteps by the use of gears. The variable-speed device, applied by the Cincinnati MillingMachine Co., Cincinnati, Ohio, to the feeds of their plain anduniversal milling machines consists of two separate and dis-tinct mechanisms, one of which transmits the power to the.
