ABSTRACT:
A typewriter of the kind having an array of typebars each movable by means of a flexible tension element or string connecting the typebar to the shank of a corresponding key, is provided with improved means connecting each string to the associated key. The string has a spherical bead at one end which is trapped between the shank of the key and a part of the body of the typewriter against which the shank slides in such a manner that the bead is pushed down on depression of the key. When the key is fitted to the typewriter during assembly the bead is drawn between the shank and the said body part by the movement of the key into place in the typewriter body.
