Transparent typewriter bail
First Claim
1. In a typewriter bail having paper rollers mounted on a bail bar for use opposite a platen of a typewriter with a bail support structure which urges the bail in operative position onto the platen, the improvement comprisingend support elements effectively mounted near the ends of the bail bar and located to seat on the platen, said end support elements being effective to space the paper rollers with a sufficiently effective clearance relative to the platen to enable the end support elements to provide substantial support of the bail bar, with said clearance further being sufficiently small to enable the paper rollers to operatively engage a sheet of paper passed around the typewriter platen.

Abstract
A transparent typewriter bail is described having a transparent bar and end support elements which seat on a typewriter platen and preserve the integrity of the shape of the transparent bar when it is installed in a typewriter. The end support elements may be in the form of rollers or adjustable elements with which one may vary the spacing between the platen and the transparent bar for optimum performance. Bowing and permanent set distortions of plastic transparent bars are effectively prevented to provide a transparent typewriter bail through which typed text can be read.

7. A transparent typewriter bail for use opposite a platen of a typewriter with a bail support structure which urges the bail in operative position onto the platen comprising
a transparent bar having opposite transparent surfaces formed to enable printed matter to be read through the bar; -
a plurality of laterally movable paper rollers mounted on the transparent bar to rotatably engage paper passing around the typewriter platen; means for mounting the ends of the transparent typewriter bar to the bail support structure; and end support elements effectively mounted near the ends of the transparent bar and located to seat on the platen, said end support elements being effective to space said rollers with a sufficiently effective clearance relative to the platen to enable the transparent bar to be effectively suspended between the end support elements with a reduction of bending of the transparent bar from the force applied by the bail support structure, said clearance being sufficiently small to enable the paper rollers to operatively grip a sheet of paper passed around the typewriter platen. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14, 15)
