There is now being made at the shops of Dietz, Gang & Co., Cincinnati, O., an engine lathe of 22 inches swing, 12 feet bed, embracing a new driving device, the invention of Mr. Frank H. Crafts, senior member of the Buffalo Woodworking Machine Co., Buffalo, N. Y. The old methods employed in driving engine lathes are completely reversed by the substitutions of Mr. Crafts invention, as the countershaft is placed on the floor directly under the spindle. Each step of the cones has its own belt. III other words, a lathe having a four-step cone would have four belts. The belts are made endless, each belt having its own tightener. These tighteners are controlled by a series of levers, and the tension of the belts can be regulated to suit the character of the work being done, and by simply throwing one tightener, and putting on another, any change of speed can be secured. There is no doubt as to the correctness of this principle for driving engine lathes, as the belts are now pulling down on the spindles, and as the tool is lifting up, the strain on the machine should be in a measure equalized. Experts who have examined the lathe, have no hesitation in predicting that this invention will entirely revolutionize the old system of driving engine lathes.
