Abstract

22,611. Lake, H. H., [Parish & Bingham Co.]. Oct. 27. Forging; stamping.-Steel sprocketwheels for bicycles are made from blanks A which are pressed cold between dies B, C adapted to compress the web to a greater extent than the rim ; the teeth having been formed by punching, the wheel is again pressed cold between dies D, E of the form shown, which round off the corners of the teeth. The cold - pressing causes surface - hardening and increased density of the parts, which is greater in the web than in the rim, and greater at the sides of the teeth than at their peripheral faces.
