Abstract: A token engraving apparatus comprising a turret movable through a path of travel between a blank token receiving station, an engraving station and an ejection station. Gravity causes blank tokens to fall from a plurality of tubular blank token holders into apertures, formed in the turret, at the blank token receiving station. The turret moves the blank tokens to the engraving station. A type head comprising a plurality of radially extending type bars moves independently of the movement of the turret so as to sequentially position the type of desired type bars above the token located at the engraving station. Located at the engraving station, above the tokens and the type ends of the type bars, is an electromechanical press. When energized the press moves the particular type bar located above the token downwardly against the upper peripheral edge of the token causing a character to be engraved therein. A type head locking mechanism locks the type head in position during engraving.

Abstract: In one exemplar embodiment, an apparatus for impressing identifying characters into the end face of metal bar stock is disclosed. A stamping apparatus operates in conjunction with conventional bar stock drawing and cutting machines. The stamping apparatus has a die positioning member adapted for pivotal movement carrying a character imprinting die that is extended and locked in the path of the moving bar stock. The force of the bar stock moving against the die imprints the identifying characters in the end face of the bar stock. Just prior to cutting of the bolt blank from the bar stock the cutting machine signals the bolt stamping apparatus and the die positioning member begins to pivot and retract into the apparatus housing thereby relieving the pressure between the end face of the bar stock and the die. The die positioning member continues to pivot into the housing as the cutting machine cuts the bolt blank from the bar stock and allows the bolt blank to fall free for collection.
