Abstract

12,122. Kearns, J. R. C., Burton, T. B., and Kearns & Co., H. W. May 22. Lathes; boring - bar machines. - The slide of a rotary tool-head is forked, as shown in Fig. 3, to pass a boring-bar E or other tool working through the hollow spindle. The slide is traversed bv projections d<1> which engage a scroll F, Fig. 1, rotated through differential gearing k from a pinion h on the spindle of the tool-head and from a worm-wheel Q driven from the change - speed box of the machine. The gearing is so proportioned that, when the wheel Q is stationary, the scroll rotates at the same speed as the tool-head. The toolbox may be adjustably mounted on the slide.
