Abstract

The figure shows a locking paper restraint for tractor feed that is designed for ease of operation and assembly. The tractor drive paper guide assembly 1 has a locking guide 2. The locking guide 2 is provided with an extension 4. Located at the end 6 of the extension 4 is a contoured grip section. The extension 4 fits into an extension acceptor 10 in the drive housing 12. When the extension 4 is positioned in the acceptor 10 of the drive housing 12, the contoured gripping section 8 contacts a guide shaft 14. When the guide shaft 14 is rotated in a counterclockwise direction, the gripping section 8 of the extension 4 is forced in a downward direction.

Locking Paper Restraint

The figure shows a locking paper restraint for tractor feed that is designed for ease of operation and assembly. The tractor drive paper guide assembly 1 has a locking guide 2. The locking guide 2 is provided with an extension 4. Located at the end 6 of the extension 4 is a contoured grip section. The extension 4 fits into an extension acceptor 10 in the drive housing 12. When the extension 4 is positioned in the acceptor 10 of the drive housing 12, the contoured gripping section 8 contacts a guide shaft 14. When the guide shaft 14 is rotated in a counterclockwise direction, the gripping section 8 of the extension 4 is forced in a downward direction. In this manner the locking guide 2 is forced against the drive housing 12, and thus the form paper is held in position against the sprocket drive 16 and between the locking guide 2 and the drive housing 12. In this manner the tractor drive restraint 1 is positioned for the acceptance of the form paper. When the guide shaft 14 is rotated in a clockwise direction, the gripping section 8 of the extension 4 is forced in an upward direction. In this manner the locking guide 2 is forced away from the sprocket drive 16, and the locking guide 2 and the drive housing 12 are positioned to accept a new paper supply. The present design is readily compatible with robotic assembly and robotic operation.
