Abstract

11,322. Adams, H. May 15. D r i l l i n g - m a - chines; drills and cutters.-A device for cutting holes and rings, or for enlarging holes, consists of a spindle formed in two parts 1, 2, each part having a conical point to serve as a pivot, the parts being connected together at 14 so as to rotate together but so as to be easily detached from each other to allow of driving- means other than ratchet to be placed on the part 1. The part 1 carries a tool-holder 5 at its end supported by a spring 6<1>, a nut 4 engaging a screw portion 3 of this part to cause feeding of the tool-holder. The upper part 2 has a nut 10 whereby the tool is fixed to do work, this nut screwing on a socket 13 for adjustment. Fig. 3 shows a tool-holder with concentric sets of holes 16, 17 adapted to hold tools for cutting-out rings.
