Abstract
6044. Lambie, J. M., Wrigley, C. R., and Lambie, J. March 10. Punching; punches. - The manufacture of nut-locking washers, of the type wherein spring tongues formed by circular sectors of a blank stand out on opposite sides of the plane of the blank, is performed in two operations by means of dies. A flat circular blank A is placed on a ring B<2> of a lower die B', Fig. 2, and an upper die with a central portion C and raised shaping-pieces D descends to punch out the centre and force down the circular sectors F, E, G, Fig. 6, without distorting the flat portion of the blank. The blank is then taken to another set of dies, Figs. 8, 9, and 10, where the circular sectors are cut radially at their middles between the edges M<1>, O<1> of the dies and then bent out to opposite sides of the plane of the blank by the ribs M, O, the arc-like division produced in the first operation being meanwhile extended, Fig. 13. The latter part of the manufacture may be done by a separate operation directly succeeding the first. The ring is ejected by the spring-pressed central plunger K supported in the lower die H.
