Abstract: A rolling parallel printer in which a pressure element is driven through a swiveling motion each printing cycle and a pressure segment thereof rolls off a line of type. The pressure element is connected to a mechanical linkage which minimizes the sweep of travel of the pressure element, while maintaining the pressure element sufficiently far from the type in a rest position to facilitate reading of the printed matter.

Abstract: A printer includes a paper transport cylinder which is intermittently driven by a motor to automatically advance the paper by one line each time a line has been printed. In order to advance the paper before printing begins a manually actuable key is provided which, when depressed, couples the transport cylinder to the motor and actuates the motor. The transport cylinder is rotated while the key is depressed to rapidly advance the paper.

Abstract: A printer, suitable for operation by an electric computer, includes a traveling carriage. The carriage carries a type-head that is vertically and rotatably shiftable to properly orient a type element for printing. Movement of the carriage, as well as vertical and rotary movement of the type-head is produced by the use of cables actuated by electromagnets. The type-head is selectively shiftable to three vertically spaced positions and selectively rotatable to eight angular positions by vertically movable levers having cables controlling their ends. Stops are provided on the carriage for precisely locating the type-head in its vertical and angular positions.A movable stop mechanism prevents the carriage from overrunning its incremental positions of step-by-step movement. Release of the carriage drive to retract the carriage to a new starting position is accomplished by activation of the platen advancing mechanism.
