Abstract
12,231. Barnett, R. E. June 13. No Patent granted (sealingfee not paid). Tools; tool-holders.-Tools for enlarging holes by internal turning consist of grooved bars combined with holders. The groove extends a short distance from the end to allow for regrinding without seriously affecting the rigidity, and may be parallel or spiral according to the cutting-angle for the material to be removed. In the form shown in Figs. 1 and 3, the groove is of such a section as to give a straight cutting-edge a b, and the end of the tool is helical. The tool-end may be ground off along the line k-l, when turning in blind holes. Fig. 4 illustrates the method of mounting the tool with regard to the axis of the work, and shows a tool having cutting-edges of different diameters. Figs. 8 and 9 show end views of two forms of suitable holders for the combination. In addition, the tool and holder may be screw-threaded. With tools of small diameter, the bar may cone out to a larger diameter at a short distance from. the cutting - end. Specification No. 12,793, A.D. 1892, is referred to.
