Abstract

385,213. Files. PEISELER, A., Haddenbach, Remscheid, Germany. June 9, 1932, No. 16324. [Class 61 (ii).] The teeth of a file, divided into groups I, II, III, IV increasing in length lengthwise of the file, are separated by parallel or staggered breaking grooves f which decrease in width and depth towards group IV. The teeth are formed by arcuate transverse grooves d, Fig. 3, which provide for a cutting angle not greater than 50‹. At the commencement of each group the grooves f are deeper than the transverse grooves d. The end teeth of each group have no grooves f.
