Gripping Arrangement for Single Line Document

This document-gripping arrangement employs the biting edges of a number of springs to prevent movement of a single line document, during printing thereon in a typewriter or terminal printer.

The arrangement includes a document chute and a number of hook-shaped springs mounted to the feed roll support. The exposed part of the chute is curved and the biting edges at the free ends of the springs are positioned so that the document is archly clamped against the biting edges during insertion of the document. The mounted portion of each spring acts as a paper stop to limit insertion of the document.

During repeated impact of the document against the platen by a printing element, the biting edges grip the document sufficiently to prevent uneven line printing but still permit the document to be withdrawn without damaging it.
