ABSTRACT:
Making characters on the periphery of a rotatable marking wheel are selectively rotated into marking position relative to the surface of a billet, ingot, bar, slab or the like by an indexing motor drivingly connected to the marking wheel. The marking wheel is rotatably mounted in a housing that is pivoted toward and away from the billet by an arm structure suspended from a frame. The frame is movable on a support transversely of the pivotal path of the marking wheel housing. The frame is laterally advanced incrementally by an indexing ratchet to move the marking wheel from one marking position to the next marking position to permit the marking wheels to stamp the billet with a series of characters. After the billet is marked with a selected character, the stepping motor rotates the marking wheel until the next desired character is in a position for marking. The frame is then laterally advanced to position the desired character opposite the billet. A lift cylinder pivots the arm structure to move the marking wheel between a raised position remote from the billet and a lowered position opposite the billet. A stamping cylinder coaxially aligned with and connected to the lift cylinder is operable to move the marking wheel housing so that the marking wheel strikes the billet and impresses the character thereon. After the marking step, the stamping cylinder retracts the marking wheel, the indexing ratchet laterally moves the frame, and the indexing motor selectively rotates the marking wheel to the desired character. Once the desired series of characters are impressed on a billet, a return cylinder is actuated to rapidly, laterally move the frame to return the marking wheel to the initial marking position for marking the next billet.
