A lead device for a drawing machine in which bars of lead are inserted in longitudinal recesses or bores in a turret drum. Each lead bar is driven by a wire at its upper end so as to project its lower end for writing. The turret is also pushed downward to project the lower end of the lead through a bore provided in a bottom plate on the machine by a press device associated with the lead bar pushing device through a friction force.
