Abstract

753,501. Graters. SCHATZSCHOCK, A., and WEITZL, A. Aug. 28, 1953 [Aug. 29, 1952; May 7,1953], No. 23881/53. Class 28(2). [Also in Groups XI, XXII and XXIII] A file, in strip, disc or drum form, for use in working metal by hand or machine, or in machines for comminuting and grinding food, comprises cutting edges 4 provided on both top and bottom edges of numerous small curved or straight portions 6 bent out of the surface of a flat or curved metal plate, the portions being joined only at their edges to the plate and the cutting edges having a clearance angle y equal to the angle that the portions form with the surface of the plate. The angles α, #, y are respectively 5, 60 and 25 degrees. The cutters 2 may be joined by flat portions 2<SP>1</SP>, Fig. 7. The gaps between the cutters may be enlarged. Drum files are made by stamping the cutters directly onto a cylindrical blank or by bending a formed strip into cylindrical or conical form and welding the ends together.
