A curved metal typing ruler for a variety of purposes including:
* curved erasing shield (especially useful for carbon copy packs to prevent carbon transfer)
* elite spacing letter counter
* line counter
* 8 inch ruler
Amidst all the typewriter paraphernalia I come across, the curved typing shield doesn’t get enough of its due. While it has some useful measurement functions, its primary functionality is as an eraser shield for erasing errors in carbon copy packs. You would move the carriage to the far right or left (to keep eraser crumbs out of your segment and machine), place the shield behind the first page and then behind each subsequent page to erase the errors from each one at a time. The smooth, curved aluminum would allow you to erase without causing the carbon papers to transfer smudges to the pages behind the shield.
The curved ruler comes with a convenient tab (here labeled “Elite”) for grabbing with one’s thumb and forefinger for placement into as well as removal from a carbon pack. They obviously came in both Pica and Elite versions to cover various typewriter typefaces.
Our friend Joe Van Cleave cleverly uses one to cleanly tear off paper from his Kerouac-like rolls of typing paper.
