  Telautograph \Tel*au"to*graph\, n. [Gr. th^le far + autograph.]
     A facsimile telegraph for reproducing writing, pictures,
     maps, etc. In the transmitter the motions of the pencil are
     communicated by levers to two rotary shafts, by which
     variations in current are produced in two separate circuits.
     In the receiver these variations are utilized by
     electromagnetic devices and levers to move a pen as the
     pencil moves. -- Tel`au*tog"ra*phist, n.
