Abstract

856,252. Making files. BOOTH, C. H. March 27, 1957 [Jan. 25, 1956 (2)], Nos. 2403/56 and 2404/56. Class 83 (2). [Also in Group XXIII] File teeth are formed before hardening by chiselling, milling, rolling to form gullets 54, Fig. 12, between projections 51 which are then bent to the required shape and ground to the same height, or, when manufactured from strip metal, by upsetting from the surface of the strip, Fig. 14. After hardening, the teeth are shaped by an abrasive structure of complementary cross-sectional shape to the teeth on the file carried on a disc.
