Abstract

In this paper inserting device for a typewriter, the actuation of an operating lever causes the platen to perform several revolutions. To prevent the paper sheets to be inserted from being damaged by knocking against the upper clamping rolls, a leverage is provided. By this the upper clamping rolls are raised off the platen during the actuation of the operating lever.

Paper Inserting Device

In this paper inserting device for a typewriter, the actuation of an operating lever causes the platen to perform several revolutions. To prevent the paper sheets to be inserted from being damaged by knocking against the upper clamping rolls, a leverage is provided. By this the upper clamping rolls are raised off the platen during the actuation of the operating lever.

Platen 1 is supported in guide 2 of stationary plate 3. In addition, it is guided in an open-top jaw of plate 4. This is displaceable in direction perpendicular to the platen. Arranged in parallel to plate 4 is an outer, displaceable plate 5 supporting the high speed paper inserting mechanism. On stub shaft 6 of platen shaft 7, pinion 8 is mounted to be freely rotatable. It is connected through clutch spring 9 to shaft 7. Pinion 8 is in mesh with toothed segment 10 of operating lever 11. From lever 11, a leverage 12 to 16 leads to support bail 17 of upper clamping roll 18.

When lever 11 is rocked forwardly, the release of clutch spring 9 is effected and causes shaft 7 to be engaged with pinion 8. In accordance with the selected transmission ratio, platen 1 performs several revolutions. At the same time, as long as the paper feeding movement continues, rolls 18 are raised off platen 1.
