Abstract

A formed sheet metal member 12 may be mounted by a screw 14 onto the tilt ring 10 of a typewriter to provide a lift shield. The tilt ring 10 will carry the shield 12 with it into all its tilted positions. The member is formed with an attaching surface 16 and a depending portion 18 by bending. Extending generally outward from the tilt ring 10 is extension portion 20 which terminates in a relatively sharp bend 22, blending into an arcuate extension 24. The radius of the arcuate extension approximates that of the external radius of the typehead.

Set N Go Erase Shield

A formed sheet metal member 12 may be mounted by a screw 14 onto the tilt ring 10 of a typewriter to provide a lift shield. The tilt ring 10 will carry the shield 12 with it into all its tilted positions. The member is formed with an attaching surface 16 and a depending portion 18 by bending. Extending generally outward from the tilt ring 10 is extension portion 20 which terminates in a relatively sharp bend 22, blending into an arcuate extension 24. The radius of the arcuate extension approximates that of the external radius of the typehead. As the tilt ring is tilted to its raised or uppermost position, the arcuate portion of the shield continues the arcuate portion of the typehead and thereby prevents the teeth on the bottom of the typehead from catching the erase tape when the typehead is then rotated back to its lowered position.

The shield may be mounted either on the top or the bottom of the tilt ring, as desired.
