ABSTRACT:
A character-carrying disc comprises, arranged on its front face, a circular arc-shaped wire spring ended by two branches, which are rectilinear and bent inwardly constituting a small fork adapted to grip the shaft of a printing machine in which the disc is used and to engage an annular groove of this shaft. This disc carries a slidable pin on a shoulder of which the central portion of the arc-shaped part of the spring bears so as to maintain the pin in an axial position in which it co-operates with a member of the machine to provide a drive connection for rotation of the disc. Thus, the spring performs a double function, ensuring on the one hand the return of the pin to its working position and on the other hand the securing of the disc on the shaft of the machine.
