Abstract

528,159. Lock-washers. JORDAN, E. April 28, 1939, No. 12814. [Class 89 (i)] [Also in Group XXII] A method of manufacturing lock-washers with radially arranged overlapping tongues is characterized in making them from a metal sheet swaging pressure being applied laterally to the tongue to bend or twist them. In manufacture holes 1 are punched in a sheet of metal and radial cuts 3 then made to form the tongues which are bent and swaged as shown in Fig. 4 by pressure applied downwardly at 5 and upwardly at 6 to provide overlapping sections. The washer is then cut out of the sheet except for two small connecting portions 7 which are broken by forcing the washer out of the sheet. Washers with the tongues arranged on the outside may be similarly made.
