Abstract

The bail device comprises a pair of handles 10 which are pivoted behind a forms feed roll 12 by pivots 14 and slots 15 and carrying an idler roll 16, as shown in the figure, such that the pivot 14, feed roll 12, and idler roll 16 are on the same center line. The pivot 14 also acts as an anchor for a tension spring 18 secured to an anchor stud 20 on the handle 10, which rides on the edge of an anchor plate 22 on which the pivot 14 is mounted. The anchor plate 22 has detent notches 24 and 26 in which the anchor stud 20 may be seated.

Constant Force Paper Bail Device

The bail device comprises a pair of handles 10 which are pivoted behind a forms feed roll 12 by pivots 14 and slots 15 and carrying an idler roll 16, as shown in the figure, such that the pivot 14, feed roll 12, and idler roll 16 are on the same center line. The pivot 14 also acts as an anchor for a tension spring 18 secured to an anchor stud 20 on the handle 10, which rides on the edge of an anchor plate 22 on which the pivot 14 is mounted. The anchor plate 22 has detent notches 24 and 26 in which the anchor stud 20 may be seated.

To operate the paper bail the handle 16 is pulled out to release the locking stud 20, whereupon the handles may be moved counterclockwise to the open position in which the lock stud 20 enters the upper notch 26. The idler roll 16 is moved up and away from the feed roll 12, permitting room to load the paper between the rolls.

To return the bail to the feed position the handles 10 are again pulled outwardly and rotated clockwise, until the stud 20 drops into the detent notch 24. The idler roll 16 is now pulled against the feed roll 12 by the spring 18.
