Abstract: A dual-element typewriter mounts the print elements a fixed distance apart with a carrier support system and operates each element from a single keyboard and selection system. A control is positionable to select the desired element. Each element is connected to opposite ends of a flexible strand and pulley system for rotating and tilting the elements to position the selected character at the print point. The control operates to prevent the rotation and tilting of one element so that the strand and pulley system moves only the element carrying the selected character to bring that character to the print point.

Abstract: A single-elment printer having a complex drive cam for control of print impact velocity, employs power taken from the print shaft within the type element carrier to perform backspace operations as selected by the velocity control mechanism.
