Abstract
Abstract Article conveying apparatus having a suitably wide conveying surface for receiving articles from a plurality of delivery conveyors, and wherein the articles are directed on the conveying surface by laterally movable pushers carried by the conveying surface to a single discharge conveyor, the pushers being guided along paths which are initially spaced apart adjacent the plurality of delivery conveyors so as to be at the outside of the articles delivered from any of the delivery conveyors and which move laterally on the conveying surface to engage the articles and progressively direct them into alignment with the single discharge conveyor, and guide means cooperating with the pushers for moving the pushers between the initially spaced apart relation and the positions aligned with the discharge conveyor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
296 words
Article combiner conveyor apparatus including: an array of article conveying members movable in an endless closed path in which said members are load bearing and form an upper surface for the support of the articles to be conveyed and follow a lower return path of travel, said members moving through said upper surface between an article receiving end and an article discharge end; article pushing means operatively mounted on said load bearing members and arranged in laterally spaced paired relation on said members so as to be initially spaced at the article receiving end of said upper surface; first guide means in said apparatus for cooperation with said pushing means, said first guide means being disposed in relation to said upper surface to progressively move said pushing means laterally on said members from the widely spaced relation at said article receiving end toward each other into a closer spaced relation sufficient at least to allow passage of articles in single file therebetween while moving with said load bearing members toward the article discharge end; second guide means cooperating with the lower return of said members for engaging said pushing means and progressively returning them to said initial widely spaced relation at the article receiving end of said upper surface; a plurality of article supply means adjacent said receiving end for delivering articles onto said upper surface from laterally spaced positions, said pusher means engaging the articles from the side thereof which is closest to the position of a pusher means as the articles and the pusher means travel with the array of conveying members for directing said articles laterally in paths along said upper surface which orient the articles for single file passage from said upper surface at substantially the same location adjacent the discharge end.
