Abstract
456,868. Files. NICHOLSON FILE CO., 23, Acorn Street, Providence, Rhode Island, U.S.A. Feb. 26, 1936, No. 5776. Convention date, Nov. 27, 1935. [Class 61 (ii)] In a double-cut file additional scorings 27 are provided as shown in Fig. 7, and these are made substantially in a longitudinal direction. The scorings may be made after the overcut 12, and before the up cut 19, or before any teeth are cut. In order to obtain uniformity of the scorings the file blank may be placed on the bed of a machine similar to that used in draw filing the blanks and securing a tool 30, Fig. 13, on a reciprocating carrier. Other methods may be employed such as by the use of straight or circular knurling tools, abrasive tools, or other cutting tools.
