Apparatus for buffering transport of document using conical screw conveyers
First Claim
1. An improved apparatus for buffering transport of a document of the type in which an upper deck is orthogonal to a plurality of opposite, parallel, threaded screw conveyers, the document is transported down the screw conveyers, and a lower deck is positioned beneath the plurality of screw conveyers for receiving the document, wherein the improvement comprises:
- (a) gear means for rotating the plurality of screw conveyers, and(b) means for moving the document horizontally from the apparatus along the lower deck, the moving means including a pusher block, a pin mounted onto a gear, and a pivotable lever having an opening with contoured surfaces operatively connected to the pusher block.

Abstract
An apparatus is provided for buffering transport of freshly inked documents. The apparatus has a plurality of opposite, parallel, threaded conical screw conveyers. Each pitch of the screw conveyer creates a drying station for an inked document. As inked documents travel upon the threads of the screw conveyers, the conical shape of the conveyers maintain the document in a substantially central position. A lower deck is provided for receiving inked documents. The buffer apparatus has a pusher mechanism to control document movement from the buffer to a downstream document handler, such as an envelope flapper.
