Abstract
663,343. File-cutting machines. WALTERS, B. Aug. 4, 1950 [Oct, 19, 1949], No. 26804/49. Class 83 (iv). In a file-cutting machine wherein a hammer 8 is carried in inclined guides in a vertically-sliding frame 5, 5A, the weight of which is applied through a metal foot 11 to hold the blank during cutting, a lever 14, 14A is pivoted to the machine base 4 at 15, and to the sliding frame at 18 and carries an adjustable load 19 for adjusting the pressure exerted by the foot. Holes 20 in the lever provide for increasing the pressure on the foot and holes 20A for reducing the pressure.
