Abstract

Abstract Driveable type dies of a teleprinter are supported in intersecting rows and columns from a type carrier which is arranged for adjustment in intersecting paths at successive stations to which the carrier is moved for presenting any selected die in a position for character reproduction. Adjustment and movement of the carrier and translocation of an impeller to successive printing stations for driving successively selected dies between print and non-print modes results from magnetomotive phenomena generated by a linear electric motor. In the magnetic flux field of the motor, a pair of mechanically coupled electrical coils are adapted magnetomotively to produce (1) vertical adjustment of an output member to which the carrier is secured and in a path corresponding to type row adjustment, (2) horizontal adjustment of a trolley from which the output member is adjustably carried and in a path corresponding to type column adjustment and (3) horizontal stepping movement of said trolley to successive printing stations. A magnetomotive force, which a third electrical coil of the motor is adapted to induce, steps the impeller to successive printing stations.
