Definitions
- my invention consists in a new and improved manufacture of malleable cast-iron axle-boxcs for wagons, and other ⁇ purposes and vehicles, by making the external and internal. surfaces of the box of a iine, steel-like hardness, and yet leave the body of the metal to retain its toughness, or malleability, to resist fracturing by sudden concussions, as would be the case .with ordinary chilled cast-iron boxes.
- Figure -l is a perspective view of the axle-box.
- Figure 2 is a perspective view of an axle-box fractured by hammering, to exhibit the toughness of the body of the metal, notwithstanding its hardened surfaces, and as distinguishing it from chilled castdron axle-boxes.
- Letter a represents the external, and b. the internal surfaces of the axle-box.
- These boxes are cast of any size and pattern desired. They are then annealed, or converted into what is technieally called malleable-iron boxes, by any of the common and well-known processes for that purpose. In this state they are put in the lathe, and turned, or iinished up to the exact dimensions required for use.
- the body of the metal is tough, or malleable, and therefore differs from chilled cast-iron axle-boxes, inasmuch as the lattei-.is always crude cast-iron, and easily fractured, while the former has been converted into a metal of a compound quality, that is, having the toughness of malleable iron, yet with surfaces of
