This gear mechanism is a positive drivflin either direction and is capable of feeding up to the limitof the belt power. Through the four-speed box at the endof the bed operating in conjunction with the cone of elevengears mounted on the inside of the bed, a range of 44 changesfor feeding and screw cutting is easily available, while themachine is in operation and without the removal of a sin-gle gear. The bed is of a patent drop V pattern, which gives 2 swing without raising the head and allows placinga great deal of extra metal in the bridge of the lead screw is placed on the inside of the bed, bringingthe pull directly under the cutting tool, thus centralizing thestrain and obviating all that tendency to twist, so commonin lathes with the screw on the outside. An elaborate series of tests was recently performed on thismachine, which we are enabled to present. T
