Abstract
662,175. Making lock-nuts. EVERY, C. E. (Illinois Tool Works). March 17, 1949, No. 7369/49. Class 83 (ii). [Also in Group XXV] In the production of nuts, with attached lock-washers, from bar stock, the end of the bar is first deeply centred, then drilled to a depth slightly greater than the thickness of the nut, the remains of the centring providing a countersink, the end of the bar is faced, leaving a thin neck 28, Fig. 11, an external groove is turned, forming the chamfer on the nut, and the end of the bore is chambered at 60, the bore thus countersunk at both ends permitting tapping without the formation of burrs, a toothed lockwasher is applied and loosely secured in place by spinning over the end of the neck by the bevelled end of a tool 62, Fig. 16, parting off at the external groove completing the manufacture.
