Device for positioning the beginning of a line in a typewriter

Angular displacements of a rotary member in, for example, a typewriter are controlled by moving a guide roller to shorten and lengthen the path of an elongate flexible member attached at one end to a rotatable stationary pulley and at its other end to an attachment piece, this member being a belt having notched ends one engaging a toothing on a part of the pulley and the other an arcuate toothed segment forming the attachment piece.

Transmission mechanism, notably for typewriters

Depressing the upper case shift key lever pivots a balance beam from a first to a second position, thereby raising the lower case shift lever to an inactive position. When the upper case shift key lever is released, the balance beam is returned to its first position, causing the lower case shift lever to fall to its active position.
