Abstract: A serial printer is provided with a multi-position flexible membrane printing element with columns and rows of print characters disposed coplanarly in spaced apart relationship therein, the flexible printing element being differentially positionable along an X and a Y axis to bring selected print characters into printing alignment with an actuatable hammer, the differential positioning of the printing element being effectuated by a rotatable crank and quadrilateral linkage means in association with a pair of position sectors and a pair of spur gears coupled to the quadrilateral linkage, the pair of position sectors being variably positionable by a first and second plurality of actuatable sector limit stops.

Abstract: An electromechanical setting mechanism is disclosed, which uses a plurality of solenoid banks to set each print wheel of a postage printing drum. Each bank features two pairs of solenoids which are mounted upon a movable frame. One pair of the two pairs of solenoids cause the frame to move with respect to the meter housing. The moving frame in turn, positions a setting linkage which sets a postage value for a print wheel. The other pair of solenoids acts directly upon this setting linkage so as to also set a postage value for the print wheel. Each solenoid is actuated by coded electrical signals, and is offset from the center of a setting link a differing amount, to provide differing resultant settings. The actuation of any or some of the solenoids, will provide any given print wheel position from zero through nine.

Abstract: Remotely controlled electric printer, to which each character to be printed is applied as m groups of n bits, comprising a set of n rulers or print bars, the total thickness of which is equal to the height of said character or a line thereof, each character having a width of m bits. Electromagnetic means are provided capable of shifting the print bars transversely with respect to one another, and there is a cross bridge or anvil that can be moved along said bars. Paper or some other printing carrier is provided between the cross bridge anvil and the bars. The electromagnetic means are so arranged that they can shift the rulers or bars transversely with respect to one another in accordance with the n-bit groups so that the rulers thereby strike the paper against the cross bridge anvil.This anvil is stepped along the line in m equal steps for each character by a pawl and rack mechanism which also is operated electromagnetically by a separate electromagnetic means.
