    摘要： A mechanism which provides bi-directional movement of the carrier of an electric typewriter incorporating proportional spacing. A ratchet arrangement is operable in both directions to provide the desired proportional spacing increments, with rotation of a ratchet wheel in the clockwise direction being controlled by engagement of an associated pawl with one of a plurality of stop engaging surfaces of a control member which sets the number of proportional spacing increments desired. For rotation of the ratchet wheel in the counterclockwise direction, a solenoid is coupled to the control member to momentarily rotate it clockwise until a stop engaging surface thereof abuts a selected stop surface corresponding to the number of proportional spacing increments desired, and causing the pawl associated with the ratchet wheel to move clockwise by a corresponding number of ratchet teeth--after which the solenoid is released, permitting a cocked spring to return the control member to its initial position and cause the pawl to rotate the ratchet wheel counterclockwise by a corresponding number of proportional spacing increments.

    摘要： A backspace device in a typewriter comprising: an interposer operable by the operation of a key lever; a cycle bail operable by the interposer; a cycle clutch for intermittently transmitting a driving force from a driving source to a main shaft so that the main shaft can be rotated by a predetermined number of times in association with the cycle bail; an actuating bail for performing a cycle of a motion along a moving path of a predetermined mode by a full turn of the main shaft, while rendering to the interposer a motion in a direction of the interposer leaving the cycle bail during the motion; a backspace link for moving in association with the interposer during the leaving motion of the interposer; a backspace rack extending laterally of the typewriter, supported rotatably about an axis laterally disposed and turned to a working position by the backspace link; and a backspace pawl fastened onto a carriage so that it can be reciprocated a predetermined distance in the lateral direction by a cam rotatable integrally with the main shaft and having a toothed portion to be meshed with the backspace rack rotated to the working position; wherein the carriage is retracted by a predetermined value of pitch along the main shaft by a reaction force generated at a portion of the engagement of the backspace pawl with the backspace rack by a motion of the backspace pawl.

    摘要： A mechanism which will function to allow the escapement of the carriage of a typewriter in one of two predetermined escapement pitches and be capable of backspace operation from a single backspace input for both pitches regardless of which escapement pitch is selected. Escapement ratchets for the two selected pitches are combined, together with a backspace ratchet. Each of the escapement ratchets are engageable by an escapement pawl and the engagement of a pawl with a particular ratchet will determine the pitch within which the escapement system will function. A backspace ratchet is combined with the escapement ratchets and fixedly attached thereto to provide the backspace drive. The backspace ratchet is selectably engageable by the backspace pawl for causing rotation in the opposite direction of that normally utilized for escapement. All motion of the escapement ratchets or backspace ratchet is transmitted through a pinion mounted to the ratchet assembly and, in turn, is transmitted to the paper carriage rack.

    摘要： A half-space carriage return mechanism for typewriters, having a rack secured to the carriage and normally engaged by an escapement dog adapted to be disengaged momentarily from the rack to letter space the carriage, comprises a pawl movable in a first direction to engage the rack and to return the carriage half a space, and means actuatable for momentarily disengaging the pawl from the rack simultaneously with disengagement of the escapement dog when and only when the pawl is in the position in which it has backspaced the carriage through half a space, to cause said carriage to be advanced offset half a space with respect to normal letter spaced positions.
